Description

Technical Field

[0001] This utility model relates to the technical field of water treatment, and in particular to a wastewater treatment device for phosphorus trichloride production. Background Technology

[0002] Phosphorus trichloride is mainly used as a raw material for manufacturing organophosphorus pesticides such as trichlorfon, methamidophos, acephate, and isoprothiolane.

[0003] Currently, phosphorus trichloride is typically synthesized directly from yellow phosphorus and chlorine under specific temperature and reaction conditions. This process generates a large amount of industrial wastewater. Additionally, wastewater discharge of varying scales occurs during equipment cleaning, exhaust gas absorption, and raw material storage. To prevent direct discharge and environmental pollution, wastewater treatment is necessary. Treatment involves discharging phosphorus-containing wastewater into a collection tank, allowing it to react naturally with calcium hypochlorite. After a period of sedimentation, the wastewater is then discharged.

[0004] However, this wastewater treatment method requires placing the pump's suction pipe directly into the treatment tank. This causes the suction pipe to draw up and discharge sediment during the pumping process, which in turn causes the inside of the pumping pipe to be blocked by sediment, affecting subsequent use. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, one objective of this utility model is to provide a wastewater treatment device for phosphorus trichloride production, which allows the pumping pipe to float on the water surface when pumping treated wastewater, thereby reducing the contact between the pumping pipe and the sediment and avoiding blockage of the pumping pipe.

[0007] To achieve the above objectives, this utility model proposes a wastewater treatment device for phosphorus trichloride production, comprising a sedimentation component, a lifting mechanism, and a pumping mechanism. The lifting mechanism is mounted on the sedimentation component; the pumping mechanism is located on one side of the sedimentation component and includes a pumping component, a floating component, and a support plate. The pumping component is located at one end of the sedimentation component, the floating component is mounted on the sedimentation component, and the support plate is installed on the sedimentation component and engaged with the floating component. The floating component includes a float plate, a limiting plate, a fixing frame, a telescopic pipe, an abutment plate, and a filter sleeve. The float plate is slidably mounted on the sedimentation component via the limiting plate, the telescopic pipe is mounted on the float plate via the fixing frame, the abutment plate is installed at the bottom end of the float plate, and the filter sleeve is fitted onto the bottom end of the telescopic pipe.

[0008] This utility model discloses a wastewater treatment device for phosphorus trichloride production. With the help of the floating component, it ensures that the water being pumped out is always from the top layer of the wastewater, thus avoiding contact with impurities. With the help of the filter sleeve, it also prevents some small impurities from being pumped out during the pumping process. As a result, when pumping out the treated wastewater, the pumping pipe can float on the water surface, thereby reducing the contact between the pumping pipe and the sediment and preventing the pumping pipe from becoming blocked.

[0009] In addition, the wastewater treatment device for phosphorus trichloride production proposed in the application may also have the following additional technical features: Specifically, the pumping assembly includes a water pump, a drain pipe, and an inlet pipe, wherein the pumping end of the water pump is connected to the telescopic pipe through the inlet pipe, and the drain pipe is connected to the outlet end of the water pump.

[0010] Specifically, the sedimentation assembly includes a sedimentation tank and a mounting platform, wherein the mounting platform is installed at one end of the sedimentation tank.

[0011] Specifically, the lifting mechanism includes a mounting plate, a bracket, a lifting assembly, a sliding frame, and a filter plate. The bracket is mounted on the sedimentation tank via the mounting plate, the lifting assembly is mounted on the bracket, the sliding frame is mounted on the sedimentation tank, and the filter plate is snapped onto the sliding frame.

[0012] Specifically, the lifting assembly includes a drive motor, a drive gear, a driven gear, a baffle, a drive ring, and a screw. The drive motor is mounted on the bracket, the drive gear is connected to the output end of the drive motor, the drive ring is rotatably mounted on the bracket, the driven gear is fixedly connected to the outside of the drive ring and meshes with the drive gear, the baffle is slidably connected to the inside of the sliding frame and is located between the filter plates, and the screw is connected to the baffle and threaded through the drive ring.

Detailed Implementation

[0016] The 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 denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The wastewater treatment device for phosphorus trichloride production according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0018] The wastewater treatment device for phosphorus trichloride production provided in this embodiment can be applied to the treatment of phosphorus trichloride production wastewater. When pumping the treated wastewater, the pumping pipe can float on the water surface, thereby reducing the contact between the pumping pipe and the sediment and avoiding blockage of the pumping pipe.

[0019] like Figures 1-3 As shown, the wastewater treatment device for phosphorus trichloride production in this embodiment of the present invention may include a sedimentation component 1, a lifting mechanism 2, and a pumping mechanism 3.

[0020] It should be noted that the bottom of the sedimentation component 1, which is away from the pumping mechanism 3, is inclined, so that the wastewater after sedimentation can be discharged to the end closer to the pumping mechanism 3.

[0021] It should be noted that the precipitation component 1 described in the above embodiments is equipped with a hoisting device (not shown in the figure, and is prior art, so it will not be described in detail).

[0022] The lifting mechanism 2 is installed on the sedimentation component 1.

[0023] Understandably, the lifting mechanism 2 connects the two internal spaces of the sedimentation component 1.

[0024] The pumping mechanism 3 is located on one side of the sedimentation component 1. The pumping mechanism 3 may include a pumping component 31, a floating component 32, and a support plate 33.

[0025] It should be noted that a pipe retractor (not shown in the figure) is installed on the support plate 33 described in the above embodiment to ensure that the pipe does not become tangled during the descent.

[0026] The pumping component 31 is located at one end of the sedimentation component 1, the floating component 32 is located on the sedimentation component 1, and the support plate 33 is installed on the sedimentation component 1 and is engaged with the floating component 32.

[0027] Understandably, the pumping component 31 is used to extract the wastewater after sedimentation in the sedimentation component 1 through the floating component 32, and the support plate 33 is used to support one end of the floating component 32, so as to prevent the pipes in the floating component 32 from becoming scattered.

[0028] The floating assembly 32 may include a float 321, a limiting plate 322, a fixing frame 323, a telescopic tube 324, an abutment plate 325, and a filter sleeve 326.

[0029] It should be noted that the bottom of the float 321 described in the above embodiment is equipped with an airbag to ensure that the float 321 always floats on the water surface.

[0030] It should be noted that the float 321 described in the above embodiment is equipped with a hanging ring (not shown in the figure), which facilitates pulling the descending float 321 up from the sedimentation assembly 1.

[0031] The float plate 321 is slidably mounted on the sedimentation assembly 1 via the limiting plate 322, the telescopic tube 324 is mounted on the float plate 321 via the fixing frame 323, the abutment plate 325 is mounted on the bottom end of the float plate 321, and the filter sleeve 326 is fitted onto the bottom end of the telescopic tube 324.

[0032] Understandably, the installation of the telescopic pipe 324 and the fixed frame 323 is completed under the action of the float plate 321, and the downward path of the float plate 321 is ensured under the action of the limiting plate 322. Subsequently, under the extraction of the pumping component 31, the telescopic pipe 324 completes the extraction of the sedimented wastewater through the filter sleeve 326. After the filter sleeve 326 contacts the sedimentation component 1, the pumping component 31 stops pumping, thereby ensuring that the sedimented impurities are not extracted by the pumping component 31.

[0033] Specifically, such as Figure 1As shown, the pumping assembly 31 may include a water pump 311, a drain pipe 312, and an inlet pipe 313.

[0034] It should be noted that the drain pipe 312 described in the above embodiments can be connected to an external water pipe, thereby facilitating the discharge of wastewater.

[0035] The pump 311 has its pumping end connected to the telescopic pipe 324 via the inlet pipe 313, and the drain pipe 312 is connected to the outlet end of the pump 311.

[0036] Specifically, under the pumping of the water pump 311, the wastewater after sedimentation is extracted through the inlet pipe 313 and the filter sleeve 326, and the extracted wastewater is discharged through the inlet pipe 313.

[0037] Specifically, in actual operation, the relevant personnel discharge the wastewater to be treated into the sedimentation component 1, and then add the wastewater treatment substance to the sedimentation component 1. After a period of sedimentation, the harmful substances in the wastewater react with the additives and settle at the bottom of the sedimentation component 1. Then, the internal structure of the sedimentation component 1 is connected by the lifting mechanism 2 to facilitate the separation of the wastewater and sediment after sedimentation. After sedimentation again, some unfiltered impurities are settled at the bottom of the sedimentation component 1. Then, the water pump 311 draws the wastewater through the inlet pipe 313 and the telescopic pipe 324. With the action of the float plate 321, it is ensured that the wastewater at the top is drawn. As the water level drops, the float plate 321 abuts against the sedimentation component 1 with the abutment plate 325 to prevent the telescopic pipe 324 from contacting the impurities settled at the bottom. During the continuous drawing process, the filter sleeve 326 further filters the impurities in the wastewater to ensure that the impurities do not enter the water pump 311. During the drawing process, the drain pipe 312 discharges the drawn wastewater.

[0038] The above-described implementation method allows the pumping pipe to float on the water surface when extracting treated wastewater, thereby reducing the contact between the pumping pipe and the sediment and preventing the pumping pipe from becoming clogged.

[0039] In one embodiment of this utility model, such as Figure 1 As shown, the sedimentation assembly 1 may include a sedimentation tank 11 and a mounting platform 12.

[0040] The mounting platform 12 is installed at one end of the sedimentation tank 11.

[0041] It is understandable that the sedimentation tank 11 is used to store and settle wastewater, and the installation platform 12 is used to install the pumping mechanism 3.

[0042] In one embodiment of this utility model, such as Figure 2As shown, the lifting mechanism 2 may include a mounting plate 21, a bracket 22, a lifting assembly 23, a sliding frame 24, and a filter plate 25.

[0043] It should be noted that the filter plate 25 described in the above embodiment is provided in two sets, and there is a gap groove between the two sets of filter plates 25 for the lifting assembly 23 to slide.

[0044] The bracket 22 is mounted on the sedimentation tank 11 via the mounting plate 21, the lifting assembly 23 is mounted on the bracket 22, the sliding frame 24 is mounted on the sedimentation tank 11, and the filter plate 25 is snapped onto the sliding frame 24.

[0045] Understandably, the installation of the lifting assembly 23 is completed under the action of the mounting plate 21 and the bracket 22, and the opening and closing of the interior of the sedimentation assembly 1 is completed under the action of the lifting assembly 23.

[0046] Specifically, such as Figure 2 As shown, the lifting assembly 23 may include a drive motor 231, a drive gear 232, a driven gear 233, a baffle 234, a drive ring 235, and a screw 236.

[0047] The drive motor 231 is mounted on the bracket 22, the drive gear 232 is connected to the output end of the drive motor 231, the drive ring 235 is rotatably mounted on the bracket 22, the driven gear 233 is fixedly connected to the outside of the drive ring 235 and meshes with the drive gear 232, the baffle 234 is slidably connected to the inside of the sliding frame 24 and is located between the filter plates 25, the screw 236 is connected to the baffle 234 and the screw 236 is threaded through the drive ring 235.

[0048] Specifically, the lifting assembly 23 is installed under the action of the mounting plate 21 and the bracket 22. Then, under the drive of the drive motor 231, the drive gear 232 rotates the driven gear 233 and the drive ring 235. Under the rotation of the drive ring 235, the screw 236 drives the baffle 234 to rise from the filter plate 25, connecting the inside of the sedimentation tank 11, so that the filtered wastewater can be discharged to the other end of the sedimentation tank 11.

[0049] In summary, the wastewater treatment device for phosphorus trichloride production according to this utility model embodiment can make the pumping pipe float on the water surface when pumping the treated wastewater, thereby reducing the contact between the pumping pipe and the sediment and avoiding blockage of the pumping pipe.
