Description

Technical Field

[0001] The invention relates to the field of wet garbage treatment, and in particular to a garbage liquid treatment device and method for wet garbage dry-wet separation. Background Art

[0002] Wet garbage refers to domestic waste containing high levels of water and organic matter, mainly including food waste, leftovers, expired food, melon peels and fruit cores, flowers and plants, Chinese medicine residues, etc. This type of garbage is easy to rot and produce odors. The treatment method of wet garbage is of great significance to environmental protection. Some of the existing wet garbage is large in volume, and it is difficult to separate wet and dry garbage, and the garbage dehydration rate is limited.

[0003] To this end, a wet garbage processing device with patent publication number CN111940453B includes a frame, a conveyor belt, a crushing device, a screw conveying device, a briquetting device, a sewage treatment device, a lifting device and a collecting device. Two main shafts are arranged inside the crushing device, each of which is provided with a spiral blade with equal pitch, each of which is provided with a spiral blade with variable pitch, and a water filter net is sleeved on the outside of the spiral blade. A water storage tank is arranged at the bottom of the crushing device, and the briquetting device includes a hammer and a push rod box. The hammer is connected to the hydraulic system. The hammer squeezes the garbage residue to form block garbage under the control of the hydraulic system, and the push rod box automatically transports the block garbage out of the briquetting device. The garbage processing device integrates the garbage crushing and dehydration devices into one. After dehydration, the garbage is compressed into blocks, so that the overall structure is not only compact and low in cost, but also capable of efficiently processing wet garbage.

[0004] The dehydration rate of the crushed garbage is improved through extrusion processing, but the dry garbage and the garbage liquid are mixed with each other after crushing, and the water content in the garbage is relatively high. It is difficult to quickly achieve a high dehydration rate through extrusion, which prolongs the time for wet garbage processing. In addition, the separated garbage liquid can be further processed by extraction and evaporation. Some existing garbage liquid processing devices are not convenient for adjusting the temperature of the garbage liquid and the flow rate of the garbage liquid during the extraction and evaporation process, which affects the efficiency of garbage liquid processing. Summary of the invention

[0005] In view of the above problems, a garbage liquid treatment device and method for dry-wet separation of wet garbage are provided. The wet and dry garbage are screened by a bulk rack that slides up and down to reduce the water content in the garbage.

The bulk rack transfers the garbage on the surface to the dewatering tank during the up and down movement, and completes the dry and wet separation under the squeezing action of the laterally moving dewatering plate.

[0019] S4, evaporation processing, the garbage liquid is conducted into the evaporation tank through the extraction tank, the temperature in the evaporation tank is controlled, the garbage liquid is evaporated and concentrated, and finally the concentrated components are discharged for incineration treatment.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is provided with a bulk rack that slides up and down to assist in screening dry and wet garbage. After the wet garbage enters the crushing tank for crushing and processing, the decomposed garbage is distributed on the surface of the bulk rack. The upper filter screen on the surface of the bulk rack screens the garbage, so that part of the garbage liquid enters the interior of the bulk rack, and then enters the dehydration tank through the drainage pipe under the bulk rack, thereby reducing the water content in the garbage in advance.

[0023] 3. The present invention is provided with a transversely movable tooth frame to improve the flow rate of garbage liquid processing. When the crushing rod rotates to decompose the garbage, the air guide tube is pushed to move back and forth laterally through the linkage stirring structure.

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figure 1-Figure 4As shown, a garbage liquid treatment device for wet garbage dry-wet separation comprises a dehydration tank 1, an extraction tank 2 which is installed through the bottom of the dehydration tank 1, and an evaporation tank 3 which is installed through the outside of the extraction tank 2. The garbage liquid treatment device also comprises a crushing tank 4 which is installed through the top of the dehydration tank 1, and a support frame 5 which is fixed to the outside of the dehydration tank 1, the extraction tank 2, the evaporation tank 3 and the crushing tank 4; a water filter frame 11 is symmetrically installed on the left and right sides of the dehydration tank 1, a lower filter screen 12 is embedded on the water filter frame 11, and a dehydration plate 13 for squeezing garbage is installed on the water filter frame 11 in a transverse sliding manner; a motor 41 is installed outside the crushing tank 4, and a crushing rod 42 is connected to the output end of the motor 41. The rod 42 is rotatably assembled inside the crushing tank 4, and a bulk rack 43 is longitudinally slidably installed in the crushing tank 4. The bulk rack 43 is engaged with the lower end of the crushing tank 4 through the electric drive lifting structure 44 installed in the dehydration tank 1 to move up and down to screen the dry and wet garbage. The bottom of the dehydration tank 1 is connected to the side of the extraction tank 2 through the water outlet pipe, and the side of the extraction tank 2 is connected to the side of the evaporation tank 3 through the water outlet pipe. The extraction tank 2 and the evaporation tank 3 are both installed with pipes for introducing reaction liquid, and the evaporation tank 3 is installed with a pipe for exhausting gas. Protective doors are slidably installed on the left and right sides of the dehydration tank 1 through electric slide rails. Controlling the opening of the protective doors can control the solid garbage squeezed inside to be discharged outward.

[0040] The wet garbage is introduced into the crushing tank 4, and the motor 41 is operated to control the crushing rods 42 to rotate. The two groups of crushing rods 42 rotate to decompose and crush the wet garbage entering the crushing tank 4. The volume of the decomposed wet garbage is reduced, and part of the water inside the wet garbage is first separated during the crushing process. The solid and liquid garbage are distributed on the bulk rack 43 below the crushing rods 42. The bulk rack 43 first separates the wet and dry garbage after the crushing to reduce the water content in the garbage. The garbage scattered on the surface of the bulk rack 43 enters the water filter rack 11 in the dehydration tank 1 when the bulk rack 43 moves downward. The dehydration plate 13 corresponds to the horizontal position on the water filter rack 11 The garbage above is squeezed by moving upward. After squeezing, the garbage is separated into dry and wet parts. The garbage liquid passes through the lower filter screen 12 and enters the bottom of the dewatering tank 1. The squeezed solid garbage is accumulated on the filter rack 11. Finally, the protective doors on the left and right sides of the dewatering tank 1 are opened to guide the squeezed solid garbage outward. The garbage liquid separated twice in the dewatering tank 1 is collected together, and the collected garbage liquid enters the extraction tank 2 and the evaporation tank 3 in turn. The garbage liquid reacts with the extraction reagent in the extraction tank 2 to separate some harmful substances in the garbage first. The garbage liquid is heated, evaporated and concentrated in the evaporation tank 3, and the concentrated garbage components are taken out from the evaporation tank 3 for incineration.

[0041] See also Figure 4-Figure 6As shown, the electric-driven lifting structure 44 includes a cylinder 441 fixed in the dewatering tank 1, a lifting slide 442 is fixedly installed at the lifting end below the cylinder 441, the lifting slide 442 is fixedly assembled on the bulk rack 43, and a guide hollow cylinder 443 is also fixed in the dewatering tank 1. The lifting slide 442 is slidably installed in the guide hollow cylinder 443, and the bulk rack 43 corresponds to the position where the dewatering tank 1 and the crushing tank 4 are connected. When the outer wall of the bulk rack 43 moves downward and is completely separated from the inner wall of the dewatering tank 1, the garbage on its surface slides into the dewatering tank 1 through the inclined surface.

[0042] The operating cylinder 441 pushes the lifting slide 442 to move up and down. The lifting slide 442 slides through the guide hollow cylinder 443. The lifting slide 442 is fixed under the bulk rack 43 to drive it to move up and down synchronously, so as to control the bulk rack 43 to move between the dewatering tank 1 and the crushing tank 4, and control the crushed garbage to be transferred between the dewatering tank 1 and the crushing tank 4. The left and right sides above the bulk rack 43 are inclined structures. The garbage is distributed on the bulk rack 43 and is transmitted downward through the inclined surfaces on the left and right sides under the action of gravity. The bulk rack 43 transfers the garbage on the surface to the water filter racks 11 on the left and right sides of the dewatering tank 1. The bulk rack 43 can disperse the garbage relatively evenly. The dewatering plates 13 in the two groups of water filter racks 11 move to squeeze the garbage respectively, reducing the amount of garbage accumulated on the side of the dewatering plate 13 on one side, so as to better squeeze the garbage to achieve dry and wet separation.

[0043] See also Figure 4 As shown, the lifting slide 442 is connected with a linkage dehydration structure 45 for driving the dehydration plate 13 to move horizontally.

[0044] When the cylinder 441 controls the lifting slide 442 to move up and down, under the transmission action of the linkage dehydration structure 45, the left and right dehydration plates 13 can be controlled to move back and forth horizontally on the water filter frame 11 accordingly, so as to realize the extrusion and dehydration treatment of the garbage on the water filter frame 11. When the cylinder 441 is started, the lifting slide 442 controls the bulk rack 43 to move up and down to pre-screen the garbage, and the cylinder 441 can control the two groups of dehydration plates 13 to move horizontally through the linkage dehydration structure 45. The linkage dehydration structure 45 can keep the bulk rack 43 and the dehydration plates 13 moving at the same time, so as to maintain the continuity of garbage treatment, and at the same time, it also reduces the driving equipment in the garbage treatment equipment, reduces the equipment cost and also reduces the size of the equipment.

[0045] See also Figure 5-Figure 7As shown, the linkage dehydration structure 45 includes a slide plate 451 fixed on the dehydration plate 13, the slide plate 451 is slidably installed on the water filter frame 11, a push rod 452 is rotatably installed on the slide plate 451, the push rod 452 is rotatably assembled with the lifting slide 442, the water filter frame 11 is erected at the bottom of the dehydration tank 1, and the lower filter screen 12 is at a certain distance from the bottom of the dehydration tank 1, so that the garbage liquid can be transmitted to the bottom of the dehydration tank 1 through the lower filter screen 12, and a through trough body is opened at the lower side of the water filter frame 11, and the garbage liquid filtered by the lower filter screen 12 flows to the middle position of the bottom surface of the dehydration tank 1 through the through trough body opened on the side of the water filter frame 11, so as to be convenient for the flow of the garbage liquid discharged from the drain pipe 432 to be collected.

[0046] When the lifting slide 442 moves up and down, the two ends of the push rod 452 connected between the lifting slide 442 and the slide plate 451 rotate accordingly, and the rotating push rod 452 pushes the slide plate 451 to slide horizontally through the water filter frame 11, and the slide plate 451 drives the dehydration plate 13 fixed on the side to move horizontally to squeeze the garbage. The garbage is separated into dry and wet parts under the squeezing effect. Since the garbage is filtered and screened once on the bulk rack 43, the water content in the garbage is reduced. Under the action of the squeezing force, the water in the garbage can be quickly squeezed out, and the bulk rack 43 disperses the garbage left and right, so that the garbage is squeezed and dehydrated on both sides of the dehydration tank 1, thereby improving the garbage dehydration efficiency.

[0047] See also Figure 3-Figure 7 As shown, upper filter screens 431 are embedded in the left and right inclined surfaces above the bulk rack 43, and a drain pipe 432 is connected to the bottom of the bulk rack 43, and the drain pipe 432 is connected to the dehydration tank 1; vibration frames 433 are correspondingly arranged on the left and right inclined surfaces above the bulk rack 43, and the vibration frame 433 is fixedly installed in the crushing tank 4, and the height of the rod below the vibration frame 433 is adapted to the inclined surface above the bulk rack 43. When the bulk rack 43 moves upward, it contacts the rod below the vibration frame 433, and the cylinder 441 pushes the bulk rack 43 to reciprocate up and down and contact the vibration frame 433, and the rod below the vibration frame 433 knocks on the upper filter screen 431 on the surface of the bulk rack 43, so that the upper filter screen 431 vibrates to clean the mesh.

[0048] The upper filter screen 431 on the inclined surface above the bulk rack 43 can first screen the garbage, so that the garbage liquid enters the bulk rack 43 and is discharged outward through the drain pipe 432 below, and the garbage liquid enters the bottom of the dehydration tank 1. When the bulk rack 43 moves up and down to transport the garbage, the upper filter screen 431 moves up and contacts the rod below the vibration frame 433. The contact of the upper filter screen 431 generates a vibration force to clean the garbage in the mesh and maintain the patency of the mesh of the upper filter screen 431.

[0049] See also Figure 8 and Fig. 9As shown, the inner walls of the extraction tank 2 and the evaporation tank 3 are fitted with tooth frames 61, and an air guide pipe 62 is connected between the tooth frames 61 inside the extraction tank 2 and the evaporation tank 3. The air guide pipe 62 penetrates and is slidably connected with the extraction tank 2 and the evaporation tank 3. A valve structure for controlling on and off is installed on the air guide pipe 62 to prevent excessive high-temperature gas from entering the tooth frame 61 in the extraction tank 2 and affecting the extraction process.

[0050] The air guide pipe 62 runs through the extraction tank 2 and the evaporation tank 3 and moves back and forth, driving the tooth frame 61 in the extraction tank 2 and the evaporation tank 3 to move horizontally synchronously. During the horizontal movement, the tooth frame 61 can accelerate the flow of the garbage liquid in the extraction tank 2 and the evaporation tank 3, thereby accelerating the extraction and evaporation of the garbage liquid.

[0051] See also Figure 8-Figure 12 As shown, a heating groove 611 for conducting hot air is opened in the gear frame 61 , and the heating groove 611 and the inside of the air guide pipe 62 are interconnected.

[0052] The waste liquid is evaporated by heating in the evaporation tank 3. The high temperature in the evaporation tank 3 is transferred to the heating groove 611 opened in the internal tooth frame 61 thereof, and the gas in the tooth frame 61 of the evaporation tank 3 is transmitted to the heating groove 611 opened in the tooth frame 61 of the extraction tank 2 through the air guide pipe 62. The gases in the heating grooves 611 of the tooth frames 61 on the left and right sides flow mutually. When the evaporation tank 3 is heated and evaporated, the internal temperature is generated high. The high temperature is transferred to the tooth frame 61 of the heat conductive material, and the gas in the heating groove 611 of the tooth frame 61 is quickly heated (the heating groove 61 1 is a sealed space, and the internal airflow flows quickly when the tooth frame 61 moves back and forth after being heated, so as to realize heat transfer). The space of the heating groove 611 in the tooth frames 61 on the left and right sides is small, and the gas convection makes the temperature on the left and right sides transfer quickly, so as to realize the transmission of part of the high-temperature gas in the evaporation tank 3 to the extraction tank 2, improve the heat utilization rate, and increase the temperature also helps to accelerate the extraction of the garbage liquid, and the left and right movement of the tooth frame 61 also accelerates the internal gas flow, so that the gas is evenly distributed in the tooth frames 61 on the left and right sides, so as to quickly conduct heat.

[0053] See also Figure 8-Figure 12 As shown, the crushing rod 42 is connected with a linkage stirring structure 7 to control the air guide pipe 62 and the gear frame 61 to slide horizontally to accelerate the flow of the garbage liquid.

[0054] When the motor 41 is started to control the crushing rod 42 to rotate, the air guide tube 62 can be controlled to move horizontally through the linkage stirring structure 7. The air guide tube 62 drives the left and right sets of tooth frames 61 to move horizontally to accelerate the flow of garbage liquid and improve the efficiency of garbage liquid extraction and evaporation.

[0055] See also Figure 8-Figure 12As shown, the linkage stirring structure 7 includes a plane gear 71 fixed to the outside of the crushing rod 42, a driving bevel gear 72 is fixedly installed on the plane gear 71, a driven bevel gear 73 is meshed and connected to the side of the driving bevel gear 72, and the driven bevel gear 73 is rotatably installed on the support frame 5, a turntable 74 is rotatably installed outside the dehydration tank 1, a pulley transmission assembly 75 is connected between the turntable 74 and the driven bevel gear 73, a slide column 76 is fixed eccentrically on the turntable 74, and a slide frame 77 is installed on the outside of the slide column 76. Fixedly mounted on the air duct 62, the pulley transmission assembly 75 is composed of two sets of pulleys and a belt wound around the outside of the pulley. The upper pulley is fixedly assembled with the driven bevel gear 73, and the lower pulley is fixedly assembled with the turntable 74. Two sets of crushing rods 42 are arranged in the crushing tank 4. The end faces of the two sets of crushing rods 42 are fixedly connected with plane gears 71. The two sets of plane gears 71 are meshed with each other. A driving bevel gear 72 is installed on the outside of one of the plane gears 71 to mesh with the driven bevel gear 73.

[0056] The starting motor 41 controls the rotation of the crushing rod 42, and the crushing rod 42 drives the plane gear 71 on the side to rotate synchronously, and actively drives the active bevel gear 72 fixed on the side of the plane gear 71 to rotate synchronously. The side of the active bevel gear 72 is meshed and assembled with the side of the driven bevel gear 73. Under the action of the meshing transmission structure, the driven bevel gear 73 can be controlled to rotate. The driven bevel gear 73 drives the turntable 74 to rotate through the pulley transmission assembly 75. During the rotation process, the turntable 74 controls the sliding column 76 to slide in the sliding frame 77. The sliding frame 77 moves back and forth laterally under the pushing action of the sliding column 76, so that the sliding frame 77 drives the air guide tube 62 to move laterally synchronously, so as to control the gear frame 61 to move laterally in the extraction tank 2 and the evaporation tank 3 to accelerate the flow of garbage liquid.
