[0002] Chemical solid waste refers to the remaining solid scraps in the process of production and utilization of chemical raw materials, or the solid waste that is contaminated and cannot be reused during the production process. In order to prevent these waste materials from polluting the environment or for recycling, it is necessary to degrade the waste through a degradation device.
[0003] Existing degradation devices generally directly transport solid waste to a degradation tank or a degradation pool, and transport a degradation bacterial solution into the degradation tank or the degradation pool for degradation treatment. However, due to the large volume of some solid waste, the contact area with the bacterial solution is small and the contact is insufficient, which will have an adverse effect on the degradation of solid waste. And after the degradation is completed, there will still be solid components remaining in the mixed solution of solid waste and bacterial solution, and a special solid-liquid separation device is still needed for solid-liquid separation, resulting in poor use effects. For this reason, we propose a chemical solid waste degradation device. Summary of the Utility Model

Specific embodiments
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0029] Refer to Figures 1 - 5 , a chemical solid waste degradation device, including a degradation tank 2, and the bottom of the degradation tank 2 is fixed on the base 1 through support legs 14. The degradation tank 2 can be supported on the base 1 through the support legs 14 and kept stable.
[0030] A control box 28 is installed on the top of the base 1, and a controller is provided in the control box 28. The controller is one of a control main board, a host, or a PLC logic controller;
[0031] Such as Figure 1As shown in the figure, a top cover 3 is installed on the top of the degradation box 2. A crushing box 5 is installed on the top of the top cover 3 through a support rod 17. Two crushing shafts 6 are rotatably connected inside the crushing box 5, and the ends of the two crushing shafts 6 are connected to a driving mechanism. The driving mechanism includes a third driving motor 24 connected to the end of one of the crushing shafts 6. The third driving motor 24 is fixed on the side wall of the crushing box 5. The third driving motor 24 is connected to the controller through a wire. The other ends of the two crushing shafts 6 are both connected with gears 7, and the two gears 7 mesh with each other. During actual use, the staff can control the operation of the third driving motor 24 through the controller. Under the action of the two gears 7, the third driving motor 24 will drive the two crushing shafts 6 to rotate in opposite directions, and perform crushing treatment on the solid waste falling into the crushing box 5.
[0032] As Figure 3 shown, a sieve plate 8 is provided below the crushing box 5. At least one connecting block 21 is symmetrically installed on both sides of the sieve plate 8. A guide rod 22 is installed between the two support rods 17 on the same side. Each connecting block 21 is slidably sleeved on the corresponding support rod 17. With the cooperation of the connecting block 21 and the guide rod 22, the sieve plate 8 can be limited, so that the sieve plate 8 remains stable.
[0033] As Figure 2 and Figure 3 shown, a second driving motor 18 is installed at one end of the top of the top cover 3 through a mounting seat 25. The second driving motor 18 is connected to the controller through a wire. An eccentric wheel 19 is installed on the output shaft of the second driving motor 18. One side of the eccentric wheel 19 is rotatably connected to a connecting rod 20. The other end of the connecting rod 20 is rotatably connected to the bottom of the sieve plate 8. During actual use, the staff controls the operation of the second driving motor 18 through the controller. Under the action of the eccentric wheel 19 and the connecting rod 20, the second driving motor 18 will drive the sieve plate 8 to reciprocate, and screen the solid waste falling on the sieve plate 8.
[0034] It should be noted that the sieve plate 8 is inclined, so that the solid waste falling on the sieve plate 8 will move along the sieve plate 8 and will not accumulate on the sieve plate 8 to block the sieve plate 8.
[0035] As Figure 1 shown, a feed hopper 9 is provided on the top of the top cover 3. The bottom of the feed hopper 9 is connected to the inside of the degradation box 2, and the feed hopper 9 is located below the sieve plate 8. The small particle solid waste falling on the sieve plate 8 will pass through the sieve plate 8 and fall into the degradation box 2 along the feed hopper 9 for degradation, and the solid waste with larger size moves along the sieve plate 8 to the bottom end of the sieve plate 8.
[0036] As Figure 1As shown, a material elevator 4 is installed on one side of the degradation tank 2. The top discharge port of the material elevator 4 extends above the crushing tank 5. The material elevator 4 is one of a Z-shaped elevator or a bucket elevator. A material guiding trough body 13 is installed on one side of the sieve plate 8. The end of the material guiding trough body 13 is located above the feed inlet of the material elevator 4. The large-sized solid waste raw materials screened by the sieve plate 8 will fall into the feed inlet of the material elevator 4 along the material guiding trough body 13 and be conveyed into the crushing tank 5 by the material elevator 4 for cyclic crushing, ensuring sufficient crushing.
[0037] As Figure 1 and Figure 5 shown, a discharge pipe 12 is installed at the bottom of one end of the degradation tank 2. A valve is installed on the discharge pipe 12, and the opening and closing of the discharge pipe 12 can be controlled through the valve. The end of the discharge pipe 12 is connected to a conveying pipe 11. The bottom of the degradation tank 2 is inclined, and the inner bottom end of the discharge pipe 12 is flush with the bottom of the degradation tank 2. In this way, when discharging after degradation, the solid waste raw materials and the bacterial liquid are discharged fully without residue.
[0038] As Figure 1 and Figure 4 shown, the conveying pipe 11 is fixed to the base 1 through a bracket, and the conveying pipe 11 is inclined. A spiral conveying shaft 26 is coaxially and rotatably connected inside the conveying pipe 11. One end of the spiral conveying shaft 26 is connected to a first driving motor 15. The first driving motor 15 is fixed to the end of the conveying pipe 11. The first driving motor 15 is connected to the controller through a wire. A discharge pipe 10 is installed on one side of the bottom of the conveying pipe 11 near the top, and a liquid discharge pipe 16 is installed on one side of the bottom of the conveying pipe 11 near the bottom. A filter screen 27 is installed at the inner top end of the liquid discharge pipe 16. In the actual use process, when the solid waste raw materials are degraded, the discharge pipe 12 can be opened, and the solid waste raw materials and the degradation bacterial liquid in the degradation tank 2 are discharged into the conveying pipe 11. Under the action of the spiral conveying shaft 26, the solid components in the mixed liquid are discharged through the discharge pipe 10, and the liquid in the mixed liquid will flow to the liquid discharge pipe 16 under the action of gravity and be discharged from the liquid discharge pipe 16 after passing through the filter screen 27.
[0039] It should be noted that the edge of the spiral conveying shaft 26 is in clearance fit with the inner wall of the conveying pipe 11. In this way, during the use process, the solid components in the mixed liquid will not remain in the conveying pipe 11.
[0040] Specifically, when the utility model is in use, the staff conveys the solid waste to the crushing box 5 through the material hoist 4. At the same time, the staff controls the third driving motor 24 to work through the controller. Under the action of the gear 7, the third driving motor 24 drives the two crushing shafts 6 to rotate in opposite directions, so as to crush the solid waste falling into the crushing box 5. The crushed solid waste falls above the sieve plate 8 under the action of gravity. At the same time, the staff controls the second driving motor 18 to work through the controller. Under the action of the eccentric wheel 19 and the connecting rod 20, the second driving motor 18 can drive the sieve plate 8 to reciprocate, so as to screen the solid waste. The solid waste with small size passes through the sieve plate 8 and falls into the degradation box 2 along the feed hopper 9 for degradation. The solid waste with large size moves along the sieve plate 8 to the material guiding trough body 13 and finally falls into the feed port of the material hoist 4 along the material guiding trough body 13, and is conveyed back to the crushing box 5 by the material hoist 4 for cyclic crushing. The crushing is sufficient, so that the solid waste can be in full contact with the degradation bacterial liquid in the degradation box 2, improving the degradation effect. When the degradation is completed, the valve on the discharge pipe 12 is opened, and the mixture of the solid waste and the bacterial liquid in the degradation box 2 flows into the conveying pipe 11 along the discharge pipe 12. At the same time, the controller controls the first driving motor 15 to work. The first driving motor 15 drives the spiral conveying shaft 26 to rotate, so as to convey the solid components in the mixture flowing into the conveying pipe 11 to the discharge pipe 10 and discharge along the discharge pipe 10. The liquid components in the mixture pass through the blades of the spiral conveying shaft 26 under the action of gravity and flow to the drain pipe 16. After the solid components in the liquid are filtered through the filter screen 27, the pure liquid components are discharged along the drain pipe 16, and the solid-liquid separation can be completed.
[0041] Furthermore, as Figure 3 shown, a border 23 is extended and provided at the top edge of the sieve plate 8. Under the action of the border 23, the solid waste falling on the sieve plate 8 can be blocked to prevent the solid waste from scattering from the edge of the sieve plate 8.
[0042] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitution or change, and should be covered within the protection scope of the utility model.
