Description

Technical Field

[0001] The utility model belongs to the technical field of hazardous waste treatment, in particular to a solid-liquid separation device for hazardous waste treatment. Background Art

[0002] Hazardous waste generally refers to waste that is toxic, corrosive, infective, flammable, radioactive and other hazardous properties. These wastes often have waste liquid attached to solid waste. In order to facilitate the treatment of hazardous waste, it is necessary to use a solid-liquid separation device to separate the hazardous waste into solid and liquid before further treatment.

[0003] In the Chinese utility model patent with the announcement number CN219663115U, a solid-liquid separation device for hazardous waste treatment is disclosed, which is provided with an extrusion mechanism, a rotation mechanism and a pushing mechanism. The hazardous waste is put into the No. 1 treatment box from the feed inlet, and then the waste is squeezed by the extrusion plate, so that the liquid leaks from the leakage plate into the No. 1 receiving box, and then the solid waste is pushed into the screen by the push plate, and then the No. 1 gear is driven to rotate by the motor, so that the No. 2 gear drives the screen to rotate, and the solid waste is separated from the solid and liquid again, and the liquid with strong viscosity is thrown into the No. 2 treatment box, and then the liquid and solid are cleaned, thereby improving the practicality of the solid-liquid separation device.

[0004] However, the device still has the following shortcomings in the actual working process: in the process of the push plate pushing the solid waste into the screen, the solid waste that was originally compressed together is easy to be scattered and missed in the No. 1 treatment box, and the sliding range of the push plate is limited, which is not convenient for pushing the solid waste completely into the screen. At the same time, one end of the screen is always in an open state. During the rotation process, the waste also has the problem of escape and splashing, which is not convenient for subsequent removal and treatment, and the waste water that is rotated out will also be scattered everywhere in the No. 2 treatment box, causing problems of difficulty in cleaning.

[0005] Therefore, there is an urgent need to improve the structure of the existing solid-liquid separation device for hazardous waste treatment, and to provide a solid-liquid separation device for hazardous waste treatment that can more fully and stably separate the solid and liquid of hazardous waste and facilitate the removal of solid waste after separation.

[0028] As a preferred embodiment, on the basis of the above structure, preferably, the solid-liquid separation component 6 includes a filter cartridge 61, a first material taking door 62, an outer sleeve 63, a second material taking door 64 and a bevel gear ring 65.

[0029] In this embodiment, the outer sleeve 63 fixedly mounted on the outside of the filter cartridge 61 can intercept the thrown-out waste water to prevent the waste water from splashing around and making the device difficult to clean.

[0030] As a preferred embodiment, based on the above structure, preferably, the filter cartridge 61 is a funnel-shaped structure, the top of the filter cartridge 61 is connected to the processing box 1 by a bearing connection, and the bevel gear ring 65 is meshedly connected with the conical gear 4.

[0031] In this embodiment, by starting the motor 3 to control the rotation of the conical teeth 4, the conical gear ring 65 meshing with the conical teeth 4 can drive the entire solid-liquid separation component 6 to rotate, thereby facilitating the rotary centrifugal dehydration.

[0032] As a preferred embodiment, based on the above structure, preferably, the second material reclaiming door 64 is located directly in front of the first material reclaiming door 62 , and the length and width of the second material reclaiming door 64 are greater than the length and width of the first material reclaiming door 62 .

[0033] In this embodiment, the first material taking door 62 and the second material taking door 64 are opened to facilitate the removal of solid waste after the solid-liquid separation is completed.

[0034] As a preferred embodiment, on the basis of the above structure, preferably, the filter press assembly 7 includes a bracket 71, a shaft 72, a gear 73, a first pulley 74, a second pulley 76 and a transmission belt 77. The bracket 71 is welded and fixed to the top of the filter cartridge 61, and one end of the bracket 71 away from the filter cartridge 61 is rotatably sleeved on the outside of the shaft 72, a gear 73 is fixed to the bottom of the shaft 72, a first pulley 74 is fixed to the top of the shaft 72, the other end of the bracket 71 is rotatably sleeved on the bottom outside of the sleeve 75, the second pulley 76 is fixedly sleeved on the outside of the sleeve 75, and the first pulley 74 and the second pulley 76 are respectively located on the inner sides of both ends of the transmission belt 77.

[0035] In this embodiment, by providing the first pulley 74, the second pulley 76 and the transmission belt 77, the sleeve 75 and the pressure plate 79 can be driven to rotate by the rotation of the gear 73.

[0036] As a preferred embodiment, based on the above structure, preferably, the gear 73 is meshed and connected with the large gear ring 5, the sleeve 75 forms a linkage mechanism with the gear 73 through the transmission belt 77, and the rotation direction of the sleeve 75 is always consistent with the rotation direction of the gear 73.

[0037] In this embodiment, the gear 73 drives the sleeve 75 and the pressure plate 79 to rotate in the opposite direction of the filter cartridge 61, which can achieve the effect of twisting and dehydrating the solid waste between the pressure plate 79 and the filter cartridge 61, thereby ensuring more complete solid-liquid separation.

[0038] As a preferred embodiment, based on the above structure, preferably, the central axes of the pressure plate 79 and the filter cartridge 61 coincide with each other, and the pressure plate 79 is slidably and sealingly connected to the bottom inner wall of the filter cartridge 61 .

[0039] In this embodiment, the solid waste inside the bottom end of the filter cartridge 61 can be squeezed and dehydrated by controlling the pressure plate 79 to move downward.

[0040] The working principle of the utility model is as follows:

[0041] When in use, first add the hazardous waste that needs to be separated into solid and liquid into the filter cartridge 61. The mesh structure of the filter cartridge 61 can be used to separate the solid and liquid. After the addition is completed, the electric telescopic rod 78 can be started to control the pressure plate 79 to move down to squeeze and dehydrate the solid waste inside the bottom end of the filter cartridge 61. Then, the motor 3 is started to control the conical teeth 4 to rotate rapidly, and the conical gear ring 65 engaged with the conical teeth 4 drives the entire solid-liquid separation component 6 to rotate rapidly and stably inside the top of the treatment box 1, so as to achieve the effect of rotating centrifugal dehydration of the solid waste. Compared with the comparative documents, the present scheme does not need to push the solid waste, and can achieve the technical effect of simultaneous operation of the two dehydration modes of extrusion and centrifugation. In addition, the outer sleeve 63 fixed on the outside of the filter cartridge 61 can intercept the thrown waste water, facilitate the waste water to flow to the bottom of the treatment box 1, and avoid the waste water splashing and making the device difficult to clean.

[0042] Since the bracket 71 is welded to the top of the filter cartridge 61, the solid-liquid separation component 6 can drive the filter press component 7 to rotate synchronously. Since the gear 73 is meshed with the large gear ring 5, when the filter press component 7 rotates, the gear 73, the shaft 72 and the first pulley 74 can rotate in the opposite direction to the filter cartridge 61, and the second pulley 76 drives the sleeve 75 and the pressure plate 79 to rotate through the transmission belt 77. The rotation direction of the pressure plate 79 is opposite to that of the filter cartridge 61. The multiple fixing strips 710 distributed in an annular manner at the bottom of the pressure plate 79 can be used to twist the solid waste between the pressure plate 79 and the filter cartridge 61, so as to improve the dehydration effect and make the solid-liquid separation more sufficient and complete.

[0043] In summary, this solution has the effect of dehydrating hazardous waste three times by squeezing, rotating centrifugation and twisting, and there is no need to push the hazardous waste to move, which can improve the adequacy of solid-liquid separation and the convenience of device operation. Finally, the wastewater can be discharged through the drain pipe 2, and the solid waste can be taken out and processed by opening the first reclaiming door 62, the second reclaiming door 64 and the third reclaiming door 8. At the same time, it should be specially noted that the installation method and the switch locking method of the first reclaiming door 62, the second reclaiming door 64 and the third reclaiming door 8 all adopt mature existing technologies, which are directly quoted in this case and therefore will not be described in detail.

[0044] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
