The lower portion of the filter (35) is provided with a flow guiding cavity. A rinse water collection trough (52) is provided at one side of the lower end surface of the material flow guiding cavity, and a material drop opening (49) is provided at the other side. The material flow guiding apparatus is provided inside the flow guiding cavity. The rinse water collection trough (52) is separated from the flow guiding cavity by a liquid filter (39). Employing the described structure, the present automatic sorting apparatus features a novel structure, stable operation, convenient replacement, high working efficiency, and a long service life.
A: Disclosed is an automatic sorting machine for sorting crabs. The automatic sorting machine comprises a feeding mechanism and a sorting mechanism, wherein the feeding mechanism is arranged in front of the sorting mechanism; a weighing mechanism and a sorting device are arranged in the sorting mechanism; the feeding mechanism is connected to the sorting device by means of a conveyor belt; the weighing mechanism is arranged below the conveyor belt; a control mechanism is arranged on one side of the conveyor belt; and the weighing mechanism and the sorting device are both connected to the control mechanism. The automatic sorting machine for sorting crabs in the present invention has a simple structure, is rationally designed and easily produced, and has a high degree of automation; crabs are weighed by means of providing the weighing mechanism, and are then sorted by means of the sorting device according to the weighing result, so that the amount of human labor is reduced, and the sorting efficiency is improved; in addition, the problem of harm to sorting personnel during the sorting process is effectively solved, so that the automatic sorting machine better meets the requirements of enterprises.
B: Disclosed is a combined wet-dry classification system for municipal household waste, comprising a dry-type fragmentation and pneumatic classification apparatus and a wet-type water separation apparatus, wherein the dry-type fragmentation and pneumatic classification apparatus comprises a feed inlet (1), a fragmentation compartment (2), a sieve (6), a pneumatic classification chamber (7), and a self-adaptive conveyor belt (9); a slow rotating cutter (3) and a fast rotating cutter (4) rotating in the same direction are provided adjacent in the fragmentation compartment, the slow rotating cutter being mounted directly below the feed inlet; a blower (8) is mounted at the left-hand side of the pneumatic classification chamber; the wet-type water separation apparatus comprises a pool (10), a feed inlet (11) provided at the front of the right-hand side of the pool, a support (12) provided above the pool, a baffle plate (13) fixedly provided on the support, a fragmenting blade (14) and a checking and selection apparatus (15), a water inlet pipe (16) provided at the left end of the pool, an overflow port (17) provided in the middle part of the pool wall at the right-hand rear end of the pool, a circulating water pump (19), a filter mesh (18), a material outlet (21), a deflector (22) and a sediment outlet helix (23); and the circulating water pump is in communication with the pool via a circulating water pipe (20). The system can be used for problems such as waste easily intertwining and jamming when fragmenting, can run continually, can completely separate corrosive organic matter, light-weight combustible matter, and inorganic matter, and the moisture content of the light-weight combustible matter is reduced.
C: Disclosed in the present invention are a kitchen waste processing method and a processing apparatus, comprising an automatic lifting material intake apparatus, a salt and grease removal apparatus, an oil-water separation apparatus, an automatic sorting apparatus, a drying apparatus, a waste heat recovery apparatus, and a control system, characterized in that a water outlet of the salt and grease removal apparatus is connected to the oil-water separation apparatus, a material outlet is connected to a material inlet of the automatic sorting apparatus, a material outlet of the automatic sorting apparatus is connected to a material inlet of a drying tank of the drying apparatus by means of an electric ball valve, an air outlet of the drying tank is connected to a vacuum pump by means of the waste heat recovery apparatus, and negative vacuum pressure is formed inside the drying tank by means of the operation of a vacuum pump. Employing the described structure, the present invention features a novel structure, a high degree of automation, a marked solid-liquid separation effect, short drying times, low power consumption, and high operational stability, and also conserves energy, is environmentally friendly, and does not emit odors, among other advantages.
D: A special vacuum excrement collection and sewage discharge treatment system comprises a waste box (4). A sewage filtering and washing apparatus (10) is mounted on one side of the waste box (4). The sewage filtering and washing apparatus (10) comprises at least a filter screen supporting cylinder (101). A filter drum (102) is accommodated inside an inner cavity of the filter screen supporting cylinder (101), and the filter drum (102) is hollow. Active carbon is disposed inside a sandwich layer formed by the inner wall surface and the outer wall surface of the filter drum (102) to form an active carbon filter layer (103). Multiple filtration pores are formed in the inner wall surface and the outer wall surface of the filter drum (102) to form a filter screen. One end of a flow guide pipe (105) provided with spray holes (104) is disposed in the inner cavity of the filter drum (102) and is used as a flushing water outlet, and the other end of the flow guide pipe (105) is disposed outside the waste box (4) and is used as a flushing water inlet. The inner cavity of the filter drum (102) is in communication with a treated-drainage water port (106) disposed on the waste box (4). An opening (107) in communication with the inner cavity of the waste box (4) is further formed in the filter screen supporting cylinder (101) and is used as an inlet for sewage to be treated and an outlet for waste after treatment. After the sewage filtering and washing apparatus (10) is additionally disposed on an existing waste box (4), liquid and solid are separated on the apparatus, the sustained use time of the system is increased, and normal use of an excrement collection system in various states can be ensured.
