Description

Technical Field

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

[0002] Hazardous waste, or the abbreviation of hazardous waste, mainly comes from the large-scale discharge of chemical, pharmaceutical, petrochemical and other industries in the daily production process. The treatment of these hazardous wastes is very important and must strictly follow environmental laws and standards to ensure that the treatment process does not pose any potential threat to the environment and human health.

[0003] Currently, for hazardous wastes containing solid and liquid components, efficient solid-liquid separation technology is a key step in achieving their effective management and treatment. Through this method, the solid part can be more easily incinerated or solidified, while the liquid part can be significantly reduced in hazard through specialized treatment methods, thus ensuring that the waste is disposed of safely and in compliance with regulations.

[0004] The currently widely used hazardous waste solid-liquid separation devices mainly rely on technical means such as filtration, centrifugal separation or filter pressing to operate. However, these methods all involve a core component during operation - the filter element. The solid part after separation tends to accumulate on the filter element and is difficult to remove quickly, which undoubtedly slows down the overall separation speed. In addition, in order to ensure that the solid-liquid separation effect is achieved as expected, the operator must pay close attention during the operation and clean up the blocked parts of the filter element in a timely manner, which undoubtedly increases the complexity and labor intensity of the operation.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The hazardous waste solid-liquid separation device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the hazardous waste solid-liquid separation device according to the embodiment of the utility model may include a housing 10 , a filter press 30 , a pressure plate 40 , a stop plate 50 and a cleaning assembly 60 .

[0023] A partition 20 is provided in the box body 10 , which divides the box body 10 into a left cavity 11 and a right cavity 12 . An inlet 13 and a liquid outlet 14 are provided on the upper and lower sides of the left cavity 11 , respectively, and a solid outlet 15 is provided on the lower side of the right cavity 12 .

[0024] The filter cartridge 30 is rotatably disposed in the left cavity 11 through a rotating mechanism 70 , and a plurality of filter holes 31 are evenly disposed on the outer surface of the filter cartridge 30 . The filter cartridge 30 is tilted and has an opening 32 on its upper side. A through hole 21 connected to the lower end of the filter cartridge 30 is disposed on the partition plate 20 .

[0025] It is understandable that hazardous waste that needs to be separated into solid and liquid can enter the filter press cartridge 30 from the inlet 13 and the opening 32 in sequence. During the process, since the opening 32 is arranged at the upper side of the filter press cartridge 30, the hazardous waste will move toward the lower side of the filter press cartridge 30 after entering the filter press cartridge 30.

[0026] Furthermore, when the pressing plate 40 moves and squeezes the hazardous waste in the filter press cartridge 30, the pressing plate 40 can first move to the other side of the opening 32 and then squeeze the hazardous waste. This can effectively prevent the hazardous waste in the filter press cartridge 30 from being discharged through the opening 32 when being squeezed.

[0027] The pressing plate 40 is slidably disposed in the filter cartridge 30 by the first cylinder 41. The abutment plate 50 is movably plugged in the through hole 21 by the second cylinder 51.

[0028] It should be noted that the pressure plate 40 and the resistance plate 50 described in this embodiment are respectively located at the two ends of the filter cartridge 30, and the pressure plate 40 can squeeze the hazardous waste in the filter cartridge 30 toward the through hole 21 under the action of the first cylinder 41. During the process, the resistance plate 50 can simultaneously block the through hole 21 and block the hazardous waste, so that the liquid part generated by the squeezing of the hazardous waste is discharged from the filter hole 31 to the left cavity 11, and finally discharged from the liquid outlet 14.

[0029] After the filtration of hazardous waste is completed, the push plate 50 can be moved to the right cavity 12 under the action of the second cylinder 51. At this time, the left cavity 11 and the right cavity 12 are connected through the through hole 21. The remaining solid part in the filter cartridge 30 can be pushed into the right cavity 12 through the through hole 21 by the pressure plate 40, and finally discharged from the solid outlet 15. This design significantly improves the overall separation speed.

[0030] The cleaning assembly 60 may include a cleaning ring 61 and a cleaning seat 62 respectively abutting against the inner and outer walls of the filter cartridge 30 , wherein the cleaning ring 61 is sleeved on the outer side of the pressure plate 40 , and the cleaning seat 62 is arranged on the left cavity 11 .

[0031] It should be noted that, without affecting the operation of the pressure plate 40, the rotating mechanism 70 described in this embodiment can drive the filter cartridge 30 to rotate. During the rotation of the filter cartridge 30, the outer wall of the filter cartridge 30 moves on the cleaning seat 62, so that the cleaning seat 62 can clean the outer wall of the filter cartridge 30. The provision of the cleaning assembly 60 can ensure the cleanliness and unobstructed flow of the filter cartridge 30.

[0032] Specifically, in the actual solid-liquid separation process of hazardous waste, the relevant personnel first place the pressure plate 40 and the abutment plate 50 at the two ends of the filter cartridge 30 respectively, and rotate the opening 32 and align it with the inlet 13. At this time, the left cavity 11 and the right cavity 12 are independent spaces.

[0033] Then the hazardous waste that needs to be separated from the solid and liquid enters the filter cartridge 30 from the inlet 13 and the opening 32 in turn. Then the relevant personnel control the pressing plate 40 to move toward the through hole 21 through the first cylinder 41. During the process, the pressing plate 40 can squeeze the hazardous waste in the filter cartridge 30, and the squeezed liquid part can be discharged from the filter hole 31 to the left cavity 11, and finally discharged from the liquid outlet 14. At the same time, after the filter press of the hazardous waste is completed, the push plate 50 can be moved to the right cavity 12 under the action of the second cylinder 51. At this time, the left cavity 11 and the right cavity 12 are connected through the through hole 21. The remaining solid part in the filter cartridge 30 can be pushed into the right cavity 12 through the through hole 21 through the pressing plate 40, and finally discharged from the solid outlet 15.

[0034] Finally, the relevant personnel control the movement and reset of the pressure plate 40. During the process, the cleaning ring 61 on the outside of the pressure plate 40 can move with the pressure plate 40 to clean the inner wall of the filter cartridge 30. When the outer wall of the filter cartridge 30 needs to be cleaned, the relevant personnel can drive the filter cartridge 30 to rotate through the rotating mechanism 70. During the rotation of the filter cartridge 30, the outer wall of the filter cartridge 30 moves on the cleaning seat 62, so that the cleaning seat 62 can clean the outer wall of the filter cartridge 30, thereby ensuring that the solid-liquid separation effect reaches the best state, while reducing the complexity of the operation and alleviating the labor burden.

[0035] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the rotating mechanism 70 may include a motor 71, a driven wheel 72 and a driving wheel 73 that are meshed with each other, wherein the driven wheel 72 is disposed at the upper end of the filter press 30, and the driving wheel 73 is connected to the motor 71 disposed on the housing 10.

[0036] Specifically, when it is necessary to control the rotation of the filter cartridge 30, the motor 71 can be started. After the motor 71 is started, it drives the driving wheel 73 connected to it to rotate. After the driving wheel 73 rotates, it drives the driven wheel 72 meshing with it to rotate synchronously. The rotation of the driven wheel 72 can drive the filter cartridge 30 to rotate.

[0037] Furthermore, if Figure 1 and Figure 3 As shown, the pressing plate 40 includes a moving shaft 42 , one end of which movably passes through the driven wheel 72 and is connected to the first cylinder 41 .

[0038] Specifically, when the rotating mechanism 70 is running and driving the filter cartridge 30 to rotate, the driven wheel 72 rotates outside the moving shaft 42. In addition, the first cylinder 41 can drive the pressing plate 40 to move inside the filter cartridge 30 through the moving shaft 42. The movement of the pressing plate 40 and the rotation of the filter cartridge 30 are independent of each other and do not interfere with each other, and both can operate smoothly.

[0039] In one embodiment of the present invention, Figure 1 As shown, a first guide plate 80 is disposed inside the left cavity 11 , and the lower side of the first guide plate 80 is connected to the liquid outlet 14 .

[0040] It can be understood that the provision of the first guide plate 80 helps the liquid portion inside the left cavity 11 to be smoothly discharged from the liquid outlet 14 under the guidance of the first guide plate 80 .

[0041] In one embodiment of the present invention, Figure 1 As shown, a second guide plate 90 is disposed inside the right cavity 12 , and the lower side of the second guide plate 90 is connected to the solid outlet 15 .

[0042] It can be understood that the provision of the second guide plate 90 helps the solid part inside the right cavity 12 to be smoothly discharged from the solid outlet 15 under the guidance of the second guide plate 90 .

[0043] In summary, in the hazardous waste solid-liquid separation device of the embodiment of the utility model, after the hazardous waste enters the filter press, it is squeezed and separated by the pressure plate, and the separated solid part can be directly discharged into the right cavity. This design significantly improves the overall separation speed. In addition, the cleaning component is arranged to ensure the cleanliness and smoothness of the filter press. The cleaning ring can move with the pressure plate to clean the inner wall of the filter press. The cleaning seat can clean the outer wall of the filter press when the filter press rotates, thereby ensuring that the solid-liquid separation effect reaches the best state, while reducing the complexity of operation and alleviating the labor burden.
