Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and in particular to a garbage disposal device. Background Art

[0002] At present, organic waste refers to the waste such as leftovers, expired food, scraps, and waste generated during the processing and consumption of food in restaurants, hotels, canteens of enterprises and institutions, food processing plants, and households, including household kitchen waste, food and vegetable waste discarded in the market, expired food and catering waste discarded by food factories, etc., which has the characteristics of large total amount, scattered sources, and easy to rot and deteriorate. The traditional method of garbage disposal adopts the method of daily production and daily cleaning, collecting organic waste from multiple sources together, and then transporting it to the garbage treatment center for centralized treatment. This treatment method requires a lot of manpower and material resources, and the collection, transportation, and treatment costs are relatively high.

[0003] In order to solve the above technical problems, according to the strong biodegradability of organic waste, waste treatment equipment in the prior art has emerged that uses bacterial degradation technology to treat organic waste on-site.

[0004] However, the current garbage treatment equipment has relatively simple functions. It only uses bacteria in the biochemical chamber to ferment the organic garbage and then directly takes it out for use, resulting in low garbage treatment efficiency and the waste gas generated in the process cannot be recycled. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a garbage disposal equipment, which has the advantages of improving garbage disposal efficiency and recycling waste gas.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A frame; a crushing knife group, wherein the crushing knife group is arranged on the frame and can crush the garbage;

[0008] a solid-liquid separation device, which is arranged on the frame and can perform solid-liquid separation on garbage; a biochemical bin, which is arranged on the frame, and wherein bacteria for fermenting garbage are arranged inside the biochemical bin; a feeding system, which is arranged on the frame and can transport garbage to the biochemical bin or the solid-liquid separation device; and a waste gas treatment device, which is arranged on the frame and can purify waste gas generated in the biochemical bin.

[0009] Through the above technical scheme, the garbage first reaches the crushing knife group, which crushes the garbage. The crushed garbage passes through the feeding system. When the humidity of the garbage is low, the feeding system can directly send it to the biochemical warehouse for fermentation. When the humidity of the garbage is high, the garbage arrives at the solid-liquid separation device through the feeding system for solid-liquid separation operation. The garbage squeezed out of water is sent to the biochemical warehouse for fermentation treatment. The waste gas generated in the fermentation process is discharged to the waste gas treatment device, and the waste gas treatment device purifies the waste gas therein. By crushing the garbage to increase the contact area of ​​​​the garbage, the garbage treatment efficiency is effectively improved while the waste gas is recycled.

[0010] Preferably, the feeding system includes a feeding base, the feeding base is provided with a feed port 1 and a discharge port 1, the solid-liquid separation device is provided with a feed port 2, the feed port 2 is connected to the discharge port 1, the output end of the solid-liquid separation device is connected to the biochemical warehouse, the feeding base is also provided with a switching device and a discharge port 2, the discharge port 1 and the discharge port 2 can be connected to the feed port 1 respectively, the switching device can control the material to be discharged from the discharge port 1 or the discharge port 2, the biochemical warehouse has a feed port 3, and the feed port 3 is connected to the discharge port 2.

[0011] Through the above technical scheme, materials with different water contents can enter the biochemical bin through two ways. When the water content is relatively large, the switching device switches the output end of the feeding base to the discharge port 1, and the material enters from the feeding port 1 and falls from the discharge port 1 to the solid-liquid separation device. After the water content is reduced in the solid-liquid separation device, it is transported to the biochemical bin from the output end of the solid-liquid separation device. When the water content is relatively small, the switching device switches the output end of the feeding base to the discharge port 2, and the material enters from the feeding port 1 and is discharged from the discharge port 2 and falls directly into the biochemical bin. In this way, materials with low water content can directly reach the biochemical bin without passing through the solid-liquid separation device, which effectively saves energy and effectively reduces equipment loss.

After the material is discharged from the discharge port 1, it falls to the feed port 2 and enters the solid-liquid separation device; when the material has a low water content, the material enters from the feed port 1, falls on the conveyor belt, and the conveyor belt reverses to transport the material in the direction of the discharge port 2.

The heated fluid begins to flow to the inlet for circulation, thereby achieving the effect of uniformly heating the working chamber. The fluid enters from the inlet and keeps the working chamber warm in the heating chamber. When the temperature drops, the fluid is discharged from the outlet. At the same time, a fluid with a higher temperature enters from the inlet.

[0019] Through the above technical solution, the exhaust gas enters the spray tower through the air inlet, the nozzle discharges water and sprays the exhaust gas, and the exhaust gas after spraying enters the delivery pipe with a large amount of water, and finally leads to the photo-oxygen purifier. In this process, the water will condense in the delivery pipe to form small water droplets.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0043] A garbage disposal device, such as Figure 1 As shown, it includes a frame 1 for fixing and installing multiple parts, and the frame 1 is provided with a feeding device 2, a crushing knife group 3, a solid-liquid separation device 4, a biochemical bin 5, a feeding system 6, and an exhaust gas treatment device 7.

[0044] The feeding device 2 comprises an inclined feeding plate 21 arranged at the upper end of the frame 1 , and the garbage is pushed from the feeding plate 21 to the crushing knife group 3 after being manually sorted.

[0045] like Figure 2As shown, the crushing knife group 3 includes a crushing box 31, a crushing shaft 1 and a crushing shaft 2 which are axially parallel and rotatably installed in the crushing box 31, bearings for reducing friction are respectively arranged between the crushing shaft 1, the crushing shaft 2 and the crushing box 31, a plurality of crushing knife discs 1 311 are sleeved on the crushing shaft 1, and a crushing knife disc 2 312 is sleeved on the crushing shaft 2, and the crushing knife discs 1 311 and 312 are arranged alternately.

[0046] Specifically, the crushing disc 1 311 and the crushing disc 2 312 are arranged to be interspersed at intervals. When the material falls from the top into the crushing box 31, it is immediately crushed by the crushing disc 1 311 and the crushing disc 2 312 and falls from the lower end of the crushing box 31 to the feeding system 6.

[0047] It should be noted that, in the present embodiment, the crushing blade group 3 can also be a structure similar to a crusher that crushes materials by rotating the bottom blade or other structures that can crush materials.

[0048] like Figures 3 to 5 As shown, the feeding system 6 includes a feeding base 61, and the feeding base 61 is provided with a feed port 1 611 and a discharge port 1 612. The solid-liquid separation device 4 is provided with a feed port 2 421, and the feed port 2 421 is connected to the discharge port 1 612. The output end of the solid-liquid separation device 4 is connected to the biochemical warehouse 5. The feeding base 61 is also provided with a switching device 62 and a discharge port 2 613. The discharge port 1 612 and the discharge port 2 613 can be connected to the feed port 1 611 respectively. The switching device 62 can control the material to be discharged from the discharge port 1 612 or the discharge port 2 613. The biochemical warehouse 5 has a feed port 3 55, and the feed port 3 55 is connected to the discharge port 2. Specifically, materials with different water contents can enter the biochemical warehouse 5 through two ways. When the water content is relatively high, the switching device 62 switches the output end of the feeding base 61 to the discharge port 1 612, and the material enters from the feeding port 1 611, and falls from the discharge port 1 612 to the solid-liquid separation device 4. After the water content is reduced in the solid-liquid separation device 4, it is transported from the output end of the solid-liquid separation device 4 to the biochemical warehouse 5. When the water content is relatively low, the switching device 62 switches the output end of the feeding base 61 to the discharge port 2 613, and the material enters from the feeding port 1 611, is discharged from the discharge port 2 613, and directly enters the biochemical warehouse 5 through the feeding port 3 55. This method allows materials with low water content to directly reach the biochemical warehouse 5 without passing through the solid-liquid separation device 4, thereby effectively saving energy and effectively reducing equipment losses.

[0049] The switching device 62 includes a rotating drive source 621 and a conveyor belt 622. The discharge port 1 612 and the discharge port 2 613 are respectively located on both sides of the conveyor belt 622. A transmission shaft 623 is respectively provided at both ends of the conveyor belt 622. The rotating drive source 621 can rotate forward or reverse, and the output end of the rotating drive source 621 is fixedly connected to the transmission shaft 623 at either end of the conveyor belt 622. The rotating drive source 621 is preferably a motor, and can also be a rotating electromagnet, an internal combustion engine or other common driving parts with a rotating function in the prior art.

[0050] It should be noted that, in the present embodiment, the switching device 62 can also be a flap structure and a rotary drive source 2. The output end of the rotary drive source 2 is fixed to the flap, and the flap is arranged between the discharge port 1 612 and the discharge port 2 613. The rotation of the flap can cover the discharge port 1 612 or the discharge port 2 613. Under the rotation of the rotary drive source 2, when the water content is low, the flap is controlled to cover the discharge port 1 612, and the material is discharged from the discharge port 2 613 and directly enters the biochemical warehouse 5. When the water content is high, the flap is controlled to cover the discharge port 2 613, and the material is discharged from the discharge port 1 612 and enters the solid-liquid separation device 4. The rotary drive source 2 is preferably a motor, and can also be other common drive parts with a rotation function such as a rotary electromagnet, a cylinder plus a connecting rod device, an internal combustion engine, etc. in the prior art.

[0051] like Figure 3 and Figure 5As shown, the solid-liquid separation device 4 includes a sleeve 42 and a feeding screw 41. The feeding screw 41 is rotatably arranged inside the sleeve 42. A second feed port 421 is arranged at one end of the sleeve 42. A third discharge port 422 is arranged at the other end of the sleeve 42. A water filter hole 46 is opened on the side wall of the sleeve 42. A baffle 43 capable of blocking the discharge port is arranged on the outer side of the sleeve 42. The material can break through the baffle 43. A return spring 44 and a fixed plate 45 are arranged on the outer side of the baffle 43. The fixed plate 45 is fixed to the outside of the sleeve 42. One end of the return spring 44 abuts against the fixed plate 45, and the other end of the return spring 44 abuts against the baffle 43. Specifically, the material enters from the second feed port 421. Through the rotation of the feeding screw 41, the material is transferred from the second feed port 421 to the third discharge port 422. In this process, due to the influence of gravity, part of the water will be discharged from the water filter hole 46. During the transmission process, due to the existence of the baffle 43, the material will accumulate at the discharge port 3 422. As the feeding screw 41 rotates, more and more materials are accumulated, which increases the pressure between the materials and the materials on the baffle 43. As the pressure increases, part of the moisture in the material is squeezed out and discharged through the water filter hole 46. When the pressure reaches a certain value, the baffle 43 is opened and the material can be pressed out. Due to the squeezing of the reset spring 44, the pressure of the baffle 43 on the material always exists, so that the moisture in the material can be continuously squeezed out again, and the sewage filtered through the water filter hole 46 is transferred to the sewage treatment tank for treatment. The material produced by the solid-liquid separation device 4 is transported to the biochemical warehouse 5 through the transmission dragon.

[0052] like Figure 6 to Figure 7As shown, the biochemical warehouse 5 includes an inner warehouse body 51, an outer warehouse body 52, a heating device 54, and an outlet. The outlet is opened on the side walls of the inner warehouse body 51 and the outer warehouse body 52 for discharging materials. The inner warehouse body 51 has a working chamber 511, and the working chamber 511 has bacterial strains. The working chamber 511 has a stirring device for stirring the materials in the working chamber 511. The stirring device is composed of a main shaft and a plurality of stirring blades installed on the main shaft. A heating chamber 53 for heating the working chamber 511 is formed between the inner warehouse body 51 and the outer warehouse body 52. ​​A fluid is distributed in the heating chamber 53. The heating device 54 is connected to the heating chamber 53 and the heating device 54 can heat the fluid. The heating chamber 53 has an inlet 531 and an outlet 532. The inlet 5 31. The outlet 532 is respectively connected to the heating device 54. A plurality of guide plates 533 are arranged between the inlet 531 and the outlet 532. A guide channel is formed between two adjacent guide plates 533. The guide channel can connect the inlet 531 and the outlet 532. Specifically, since the fluid has fluidity, it can fill the entire heating chamber 53, so that the working chamber 511 can be evenly heated. The fluid is heated by the heating device 54, and the fluid heated in the heating device 54 is transported to the heating chamber 53. After the temperature of the fluid drops, it is transported to the heating device 54 for heating again. Finally, the working chamber 511 is uniformly heated, the activity of the bacterial agent is improved, and thus the output efficiency and quality of the biochemical warehouse 5 are improved.

[0053] It should be noted that in this embodiment, the heating device 54 is a fuel heat conduction furnace or an electric heating heat conduction furnace or the like for heating, preferably an electric heating heat conduction furnace, which is connected to the inlet 531 and the outlet 532 through a transport pipe.

[0054] like Figures 8 to 9As shown, the materials or waste gas generated in the biochemical warehouse 5 enter the waste gas treatment device 7, and the waste gas treatment device 7 includes a spray tower 71 and a photo-oxygen purifier 72. The lower end of the spray tower 71 is provided with an air inlet 711 for the waste gas to enter, and the upper end of the spray tower 71 is provided with an air outlet 712. The inner wall of the spray tower 71 is installed with a plurality of nozzles 713. A conveying pipe 73 is provided between the air outlet 712 and the photo-oxygen purifier 72 for communication. The conveying pipe 73 is bent downward to form a concave section 731. The lowest point of the concave section 731 is provided with a drain port 732. Specifically, the waste gas enters the spray tower 71 through the air inlet 711, and the nozzle 713 discharges water and sprays the waste gas. After spraying, the waste gas enters the The delivery pipe 73 eventually leads to the photo-oxygen purifier 72 for purification and discharge. In this process, moisture will condense in the delivery pipe 73 to form small water droplets. The drain port 732 is opened at the lowest point of the concave section 731 of the delivery pipe 73, so that under the action of gravitational potential energy, the small water droplets will gather to the drain port 732 and be discharged through the drain port 732. The interior of the spray tower 71 is vertically arranged with a plurality of filter ball layers 714. The filter ball layer 714 includes a plurality of filter balls for filtering impurities, and the material thereof is ceramic or other materials with adsorption capacity. The interior of the spray tower 71 is vertically arranged with a plurality of placement plates 715 corresponding to the filter ball layers 714 one by one, and the filter ball layers 714 are placed on the placement plates 715.

[0055] It should be noted that the photo-oxygen purifier 72 is a relatively common product on the market. It mainly uses a specially made high-energy, high-ozone UV ultraviolet light beam to irradiate the waste gas, crack the industrial waste gas, and use a high-energy, high-ozone WV ultraviolet light beam to decompose the oxygen molecules and water molecules in the air, thereby producing ozone that has extremely strong oxidizing properties to organic matter.

The valve body 2 8131, the humidity detector 83 is electrically connected to the valve body 1 8121 and the valve body 2 8131 respectively. Specifically, when the dust removal device 8 is working, the exhaust gas enters from the air inlet section 811, and the humidity detector 83 is used to detect the exhaust gas humidity in the air inlet section 811 and output a signal to the valve body 1 8121 and the valve body 2 8131. When the humidity is high, the valve body 1 8121 is opened, the valve body 2 8131 is closed, the exhaust gas is discharged from the air outlet 2 8122 and enters the subsequent steps. When the humidity is low, the valve body 2 8131 is opened, the valve body 1 8121 is closed, the exhaust gas is discharged from the air outlet 3 8132 and enters the dust removal component 82, and the dust in the exhaust gas is removed by the dust removal component 82.

[0057] The dust removal assembly 82 includes a dust removal bin 821 and a filter bag 822. An air inlet 823 is provided at the lower end of the dust removal bin 821. An air outlet 824 is provided at the upper end of the dust removal bin 821. The filter bag 822 is installed in the dust removal bin 821 and is located between the air inlet 823 and the air outlet 824. The air inlet 811 is connected to the air outlet 8122 and the air outlet 824 respectively. The filter bag 822 in the dust removal bin 821 can effectively intercept dust, so that the exhaust gas can be discharged from the air inlet. During the process of entering through the air outlet 823 and being discharged through the air outlet 824, most of the dust can be filtered out. A pulse solenoid valve is provided at the upper end of the dust removal bin 821 for releasing pulses to make the dust adsorbed on the filter bag 822 fall off. The output end of the pulse solenoid valve faces the filter bag 822. A discharge hole is also provided at the lower end of the dust removal bin 821. The air inlet 711 is respectively connected with the air outlet 8122 and the air outlet 4 824, so that no matter how high or low the humidity is, the exhaust gas will eventually flow to the air inlet 711 and enter the spray tower 71.

[0058] Working principle: after the garbage is manually sorted on the feed plate 21, it is pushed to the crushing knife group 3. After the garbage reaches the crushing knife group 3, the crushing knife disc 1 311 and the crushing knife disc 2 312 in the crushing knife group 3 crush the garbage. The crushed garbage falls out from the lower end of the crushing knife group 3 and falls into the feed port 1 611 of the feeding system 6. It is distributed through the feeding system 6. Materials with different water contents can enter the biochemical warehouse 5 through two ways. When the water content is large, the switching device 62 switches the output end of the feeding base 61 to the discharge port 1 612. The material enters from the feed port 1 611 and falls from the discharge port 1 612 to the solid-liquid separation device 4. After the water content is reduced in the device 4, it is transported from the output end of the solid-liquid separation device 4 to the biochemical warehouse 5. When the water content is small, the switching device 62 switches the output end of the feeding base 61 to the discharge port 2 613. The material enters from the feed port 1 611, is discharged from the discharge port 2 613 and directly enters the biochemical warehouse 5 through the feed port 3 55. The bacteria in the biochemical warehouse 5 ferment the material, and the waste gas generated during the fermentation process is discharged to the waste gas treatment device 7, and the waste gas therein is purified by the spray tower 71 and the photo-oxygen purifier 72. The garbage treatment efficiency can be effectively improved by increasing the contact area of ​​the garbage by crushing and increasing the activity of the bacteria by constant temperature.
