Description

Technical Field

[0001] This utility model relates to the field of hazardous wastewater pumping technology, and in particular to a hazardous wastewater pumping system. Background Technology

[0002] In the recycling of waste lithium batteries, non-recyclable ternary lithium battery cells from the cascade utilization system, along with acquired waste 3C digital batteries, are placed together in a 10-15% sodium sulfate saline solution (saltwater discharge ensures high and stable discharge efficiency). The positive and negative electrodes are short-circuited for discharge, which takes approximately 24-50 hours, until the residual charge is completely discharged. The working conditions are normal temperature and pressure. After the residual charge is discharged, the cells are drained using a special hoist and transferred to a conveying hopper. Because the generated waste brine is rich in heavy metals and other harmful components, it needs to be pumped out. Generally, a hand-cranked pump (such as the one disclosed in application number 200520133447.2) is used to pump the waste brine from the tank to the target container. If the number of waste batteries is small, a concentrated brine solution from one tank can be used to discharge the waste batteries. At this time, the hand-cranked pump with the above structure is applicable. However, if there are a large number of waste batteries and multiple tanks of concentrated brine are discharging the waste batteries at the same time, the hand-cranked pump with the above structure cannot be driven by a single driver when multiple pumps are used together. Instead, multiple workers are required to operate it. This mode not only increases labor costs but also leads to low efficiency in pumping out waste brine. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a hazardous wastewater pumping system to solve the technical problem that when multiple hand-cranked pumps are used in combination, they cannot be driven by a single driver and require multiple operators, which not only increases labor costs but also leads to low efficiency in pumping wastewater.

[0004] To achieve the above technical objectives, the present invention provides a hazardous wastewater pumping and discharge system, comprising:

The outlet end of the second pipe body of the second one-way valve is used to connect to the target container. When the pressure inside the cylinder is greater than the external pressure, the first valve plate of the first one-way valve is attached to the orifice of the first mounting ring. When the pressure inside the cylinder is less than the external pressure, the second valve plate of the second one-way valve is attached to the orifice of the second mounting ring.

The drive assembly includes a bearing, a drive shaft, a perforated rod, a rotating disk, an end cap, a sliding shaft, an elastic element, and a rocker arm. The outer ring of the bearing is fixedly connected to the cylinder. The drive shaft extends radially along the cylinder and passes through the inner ring of the bearing and the cylinder. One end of the drive shaft is located inside the cylinder, and the other end is located outside the cylinder. The drive shaft is interference-fitted with the inner ring of the bearing. The drive shaft has a perforated hole extending along its length. The perforated rod slides... The flower rod passes through the flower hole, with one end located inside the cylinder and the other end located outside the cylinder. The rotating disk is disposed inside the cylinder and is coaxially and fixedly connected to one end of the flower rod.

One end of each transmission component is connected to the moving component, and the other end of each transmission component is fixedly connected to each second connecting disc, so as to convert the reciprocating linear motion of the moving component into the reciprocating motion of each second connecting disc along the axial direction of the corresponding cylinder.

[0014] Furthermore, the moving component includes a moving rod and a telescopic drive. The moving rod is arranged along the arrangement direction of each of the pumping mechanisms and is perpendicular to each of the cylinders. The output end of the telescopic drive is fixedly connected to one end of the moving rod and is used to drive the moving rod to reciprocate linearly along the arrangement direction of each of the pumping mechanisms. One end of each of the transmission components is connected to the moving rod to convert the reciprocating linear motion of the moving rod into the axial reciprocating motion of each of the second connecting discs along the corresponding cylinder.

The number of water tanks containing hazardous wastewater to be pumped is used to determine the pumping mechanism to be activated. When a pumping mechanism needs to be activated, the corresponding connecting part is detachably connected to the corresponding piston assembly. By controlling the drive unit, the drive unit can drive the corresponding connecting part to reciprocate along the axial direction of the corresponding cylinder, thereby causing the corresponding piston assembly to reciprocate along the axial direction of the corresponding cylinder. During the reciprocating movement of the piston assembly along the axial direction of the cylinder, the hazardous wastewater in the water tank can be pumped into the target container, thereby realizing the function of pumping out the hazardous wastewater in the water tank. This hazardous wastewater pumping system allows for the selection of pumping mechanisms based on the number of tanks containing hazardous wastewater to be pumped. For multiple pumping mechanisms used in combination, only one driver is required, avoiding the problem of multiple manual pumps requiring multiple operators when used together, which cannot be driven by a single driver. This reduces labor costs and improves the efficiency of pumping out wastewater. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a hazardous wastewater pumping and discharge system, the structure of which is as follows: Figure 1 - Figure 3 As shown, the device includes multiple pumping mechanisms 100 and a driving mechanism 200. Each pumping mechanism 100 includes a cylinder 110 and a piston assembly 120. The cylinder 110 has a closable inlet 111 and an outlet 112. The piston assembly 120 is slidably and sealed within the cylinder 110. The driving mechanism 200 has multiple connecting parts and a driving part. Each connecting part is detachably connected to each piston assembly 120. The driving part is connected to each connecting part and is used to drive each connecting part to reciprocate along the axial direction of the corresponding cylinder 110, so that each piston assembly 120 reciprocates along the axial direction of the corresponding cylinder 110.

[0025] In use, each of the inlets 111 is connected to a corresponding water tank, and each of the outlets 112 is connected to the target container. The number of water tanks containing hazardous wastewater to be pumped determines which pumping mechanism 100 needs to be activated. When a pumping mechanism 100 needs to be activated, the corresponding connecting part is detachably connected to the corresponding piston assembly 120. By operating the drive unit, the drive unit can drive the corresponding connecting part to reciprocate along the axial direction of the corresponding cylinder 110, thereby causing the corresponding piston assembly 120 to reciprocate along the axial direction of the corresponding cylinder 110. During the reciprocating movement of the piston assembly 120 along the axial direction of the cylinder 110, the hazardous wastewater in the water tank can be pumped into the target container, thereby realizing the function of pumping out the hazardous wastewater in the water tank. In this hazardous wastewater pumping system, the number of pumping mechanisms 100 to be activated can be determined according to the actual number of water tanks containing hazardous wastewater to be pumped. For the combined use of multiple pumping mechanisms 100, only one driver is used for driving, avoiding the problem that when multiple traditional hand-cranked pumps are used in combination, multiple drivers cannot be used and multiple operators are required to operate them, thereby reducing labor costs and improving the efficiency of pumping out waste brine.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3 The cylindrical body 110 is vertically arranged and includes a cylindrical body 113 and a cylindrical cover 114. The top of the cylindrical body 113 is open, and the middle section of the cylindrical body 113 has an inlet 111 and an outlet 112. The lower section of the cylindrical body 113 has a conical structure, and the bottom of the cylindrical body 113 has a closable drain outlet 1131. The cylindrical cover 114 covers the opening at the top of the cylindrical body 113 and is detachably and fixedly connected to the cylindrical body 113. The piston assembly 12... The piston assembly 120 is positioned above the inlet 111 and the outlet 112. The upper end of the piston assembly 120 slides through the cover 114 and extends out of the cylinder 110. The connecting part is detachably connected to the upper end of the piston assembly 120. After the hazardous wastewater is pumped out, a small amount of bottom liquid will remain at the bottom of the cylinder 113. Opening the drain outlet 1131 can drain the small amount of bottom liquid remaining in the cylinder 113. The lower section of the cylinder 113 has a conical structure to facilitate the complete drainage of the bottom liquid.

[0027] As a preferred embodiment, please refer to Figure 1 and Figure 3The piston assembly 120 includes a piston 121, a connecting rod 122, and a first connecting plate 123. The piston 121 is slidably disposed within the cylinder 110. The connecting rod 122 is arranged axially along the cylinder 110, with one end fixedly connected to the piston 121 and the other end located outside the cylinder 110. The first connecting plate 123 is fixedly connected to the other end of the connecting rod 122. The connecting part is detachably connected to the first connecting plate 123. When a certain pumping mechanism 100 needs to be activated, the corresponding connecting part is connected to the corresponding first connecting plate 123. 23 is detachably connected. By operating the drive unit, the drive unit can drive the corresponding connecting part to reciprocate along the axial direction of the corresponding cylinder 110, thereby causing the corresponding first connecting plate 123 to reciprocate along the axial direction of the corresponding cylinder 110. In turn, the corresponding piston 121 is driven to reciprocate along the axial direction of the corresponding cylinder 110 via the corresponding connecting rod 122. During the reciprocating movement of the piston 121 along the axial direction of the cylinder 110, the hazardous wastewater in the water tank can be pumped into the target container, thereby realizing the function of pumping out the hazardous wastewater in the water tank.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 The pumping mechanism 100 also includes two one-way valves 130. The first one-way valve 130 is located at the inlet 111 to allow wastewater to flow only from the outside of the cylinder 110 to the inside of the cylinder 110. The second one-way valve 130 is located at the outlet 112 to allow wastewater to flow only from the inside of the cylinder 110 to the outside of the cylinder 110. When the piston 121 moves upward, the first one-way valve 130 opens and the second one-way valve 130 closes, the inlet 111 opens and the outlet 112 closes, and the hazardous wastewater in the tank enters the cylinder 110 through the inlet 111. When the piston 121 moves downward, the first one-way valve 130 closes and the second one-way valve 130 opens, the inlet 111 closes and the outlet 112 opens, and the hazardous wastewater in the cylinder 110 is discharged into the target container through the outlet 112.

[0029] As a preferred embodiment, please refer to Figure 4The one-way valve 130 includes a pipe body 131, a mounting ring 132, a lug 133, and a valve plate 134. The pipe body 131 has an inlet end and an outlet end. The mounting ring 132 is fixedly disposed within the pipe body 131. The lug 133 is disposed within the pipe body 131 and located on the side of the mounting ring 132 near the outlet end of the pipe body 131. The lug 133 is fixedly connected to the mounting ring 132. The valve plate 134 is disposed within the pipe body 131 and located on the side of the mounting ring 132 near the outlet end of the pipe body 131. The valve plate 134 is connected to the lug 132 via a pin. 33. The outlet end of the first tube body 131 of the first one-way valve 130 is connected to the inlet 111, and the inlet end of the first tube body 131 of the first one-way valve 130 is used to connect to the water tank. The inlet end of the second tube body 131 of the second one-way valve 130 is connected to the outlet 112, and the outlet end of the second tube body 131 of the second one-way valve 130 is used to connect to the target container. When the pressure inside the cylinder 110 is greater than the external pressure, the first valve plate 134 of the first one-way valve 130 is attached to the orifice of the first mounting ring 132. When the pressure inside the cylinder 110 is less than the external pressure... The second valve plate 134 of the second one-way valve 130 is attached to the orifice of the second mounting ring 132. During the operation of pumping out hazardous wastewater, the piston 121 moves upward first. At this time, the space below the piston 121 increases, and the pressure decreases. The pressure in the space below the piston 121 is less than the external pressure. The first valve plate 134 moves away from the first mounting ring 132, and the second valve plate 134 is attached to the orifice of the second mounting ring 132. The first pipe 131 is in a conductive state, and the second pipe 131 is in a cut-off state. The hazardous wastewater in the tank is forced in by atmospheric pressure. The first tube 131 then enters the space below the piston 121. The piston 121 then moves downward. At this time, the space below the piston 121 decreases, and the pressure increases. The pressure in the space below the piston 121 is greater than the external pressure. The first valve plate 134 is attached to the orifice of the first mounting ring 132, and the second valve plate 134 is away from the second mounting ring 132. The first tube 131 is in a cut-off state, and the second tube 131 is in a conductive state. The hazardous wastewater in the space below the piston 121 enters the second tube 131 and is discharged into the target container.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 5The pumping mechanism 100 further includes a drive assembly 140, which is detachably connected to the piston assembly 120 and is used to drive the piston assembly 120 to reciprocate along the axial direction of the cylinder 110. When only one tank of hazardous wastewater needs to be pumped out, the corresponding connecting part can be detachably connected to the corresponding first connecting plate 123. By operating the drive assembly, the corresponding connecting part is driven to reciprocate along the axial direction of the corresponding cylinder 110, thereby causing the corresponding first connecting plate 123 to reciprocate along the corresponding direction. The axial reciprocating movement of the cylinder 110 drives the corresponding piston 121 to reciprocate along the axial direction of the cylinder 110 via the corresponding connecting rod 122, thereby realizing the function of pumping out hazardous wastewater in the tank. Alternatively, the drive assembly 140 can be detachably connected to the piston assembly 120, and the drive assembly 140 drives the piston assembly 120 to reciprocate along the axial direction of the cylinder 110. In this hazardous wastewater pumping system, the pumping mechanism 100 can be used alone or multiple units can be used in combination and driven by a single driver, making it highly adaptable.

[0031] As a preferred embodiment, please refer to Figure 5The piston assembly 120 further includes a slide rod 124, which is perpendicular to and fixedly connected to the connecting rod 122. A groove 1241 extending along the length of the slide rod 124 is formed on the slide rod 124. The drive assembly 140 includes a bearing 141, a drive shaft 142, a spiral rod 143, a rotating disk 144, an end cap 145, a sliding shaft 146, an elastic element 147, and a rocker arm 148. The outer ring of the bearing 141 is fixedly connected to the cylinder 110. The drive shaft 142 extends radially along the cylinder 110 and passes through the inner ring of the bearing 141 and the cylinder 110. One end of the drive shaft 142 is located inside the cylinder 110, and the other end is located... Outside the cylindrical body 110, the drive shaft 142 is interference-fitted with the inner ring of the bearing 141. The drive shaft 142 has a perforated hole extending along its length. The perforated rod 143 slides through the perforated hole. One end of the perforated rod 143 is located inside the cylindrical body 110, and the other end is located outside the cylindrical body 110. The rotating disk 144 is disposed inside the cylindrical body 110 and coaxially fixedly connected to one end of the perforated rod 143. The end cap 145 is detachably fixedly connected to the other end of the perforated rod 143. The sliding shaft 146 is disposed inside the cylindrical body 110 and parallel to the sliding rod 124. One end of the sliding shaft 146 is eccentrically fixedly connected to the rotating disk 144. The elastic element... 147 is sleeved on the flower rod 143. Both ends of the elastic element 147 are connected to the other end of the drive shaft 142 and the end cap 145, respectively, so that the sliding shaft 146 abuts into the groove 1241. One end of the rocker arm 148 is fixedly connected to the other end of the drive shaft 142 for driving the drive shaft 142 to rotate. When the pumping mechanism 100 is used alone, the sliding shaft 146 abuts into the groove 1241 under the action of the elastic element 147, thereby achieving a sliding connection with the slide rod 124 of the piston assembly 120. Then, manually rotating the rocker arm 148 can drive the drive shaft 142 to rotate. Since the flower rod 143 is connected to the flower hole on the drive shaft 142... Therefore, the flower rod 143 can only move axially along the drive shaft 142 and cannot rotate relative to the drive shaft 142. When the drive shaft 142 rotates, the flower rod 143 will rotate synchronously, thereby driving the rotating disk 144 and the sliding shaft 146 to rotate synchronously. Since the sliding shaft 146 is restricted by the groove 1241 on the sliding rod 124, when the sliding shaft 146 rotates, it will cause the sliding rod 124 to move up and down, thereby causing the connecting rod 122 to move up and down, and thus driving the piston 121 to move up and down. When multiple pumping mechanisms 100 need to be used in conjunction, the flower rod 143 is pulled outward, causing the sliding shaft 146 to move out of the groove 1241. At this time,The drive assembly 140 is separated from the slide rod 124 of the piston assembly 120, and then the connecting part of the drive mechanism 200 is detachably connected to the corresponding second connecting plate 210 to complete the assembly of the drive mechanism 200 and the piston assembly 120 of the pumping mechanism 100.

[0032] In a preferred embodiment, the elastic element 147 is a spring.

[0033] In a preferred embodiment, the drive assembly 140 further includes at least one push rod. Pulling the flower rod 143 outwards causes the sliding shaft 146 to move out of the groove 1241, increasing the distance between the end cap 145 and the other end of the drive shaft 142. The push rod is positioned between the end cap 145 and the other end of the drive shaft 142, with both ends of the push rod abutting against the end cap 145 and the other end of the drive shaft 142, respectively, so that the sliding shaft 146 is in a separated state from the groove 1241. When multiple pumping mechanisms 100 need to... When used in combination, pulling the flower rod 143 outward causes the sliding shaft 146 to move out of the groove 1241. At this time, the distance between the end cap 145 and the other end of the drive shaft 142 increases, and the elastic element 147 is in a stretched state. Placing the top rod between the end cap 145 and the other end of the drive shaft 142, and making the two ends of the top rod abut against the end cap 145 and the other end of the drive shaft 142 respectively, can keep the sliding shaft 146 in a separated state from the groove 1241, avoiding continuous action on the flower rod 143 by a person.

[0034] As a preferred embodiment, please refer to Figure 3 The pumping mechanism 100 also includes a drain valve 150, the inlet end of which is connected to the drain outlet 1131 and is used to control the opening and closing of the drain outlet 1131, thereby enabling the discharge of the bottom liquid inside the cylinder 110. At the same time, the drain outlet 1131 can also be closed, ensuring the smooth operation of the hazardous wastewater pumping operation inside the cylinder 110.

[0035] In a preferred embodiment, the drain valve 150 is a ball valve.

[0036] In a preferred embodiment, the pumping mechanism 100 further includes a filter screen, which is disposed at the inlet end of the first pipe body 131 and is used to filter out impurities in the hazardous wastewater.

[0037] As a preferred embodiment, please refer to Figure 1The pumping mechanisms 100 are arranged side-by-side and spaced apart. The drive mechanism 200 includes multiple second connecting discs 210, a moving component 220, and multiple transmission components 230. The second connecting discs 210 form the connecting part, and each second connecting disc 210 is detachably connected to each first connecting disc 123 via screws. The moving component 220 and the multiple transmission components 230 form the drive part. The moving component 220 can reciprocate linearly along the arrangement direction of each pumping mechanism 100. One end of each transmission component 230 is connected to the moving component 220, and the other end of each transmission component 230 is fixedly connected to each second connecting disc 210, so as to convert the reciprocating linear motion of the moving component 220 into the reciprocating movement of each second connecting disc 210 along the axial direction of the corresponding cylinder 110. When a certain pumping mechanism 100 is in operation, the corresponding second connecting plate 210 is detachably connected to the corresponding first connecting plate 123. By manipulating the moving component 220, the moving component 220 is made to reciprocate linearly along the arrangement direction of each pumping mechanism 100. The corresponding transmission component 230 converts the reciprocating linear motion of the moving component 220 into the reciprocating motion of the corresponding second connecting plate 210 along the axial direction of the corresponding cylinder 110. This causes the corresponding first connecting plate 123 to reciprocate along the axial direction of the corresponding cylinder 110. Then, via the corresponding connecting rod 122, the corresponding piston 121 is driven to reciprocate along the axial direction of the corresponding cylinder 110. During the reciprocating motion of the piston 121 along the axial direction of the cylinder 110, the hazardous wastewater in the water tank can be pumped into the target container, thereby realizing the function of pumping out the hazardous wastewater in the water tank.

[0038] As a preferred embodiment, please refer to Figure 1 The moving component 220 includes a moving rod 221 and a telescopic drive component 222. The moving rod 221 is arranged along the arrangement direction of each of the pumping mechanisms 100 and is perpendicular to each of the cylinders 110. The output end of the telescopic drive component 222 is fixedly connected to one end of the moving rod 221 and is used to drive the moving rod 221 to reciprocate linearly along the arrangement direction of each of the pumping mechanisms 100. One end of each of the transmission components 230 is connected to the moving rod 221 to convert the reciprocating linear motion of the moving rod 221 into the reciprocating motion of each of the second connecting discs 210 along the axial direction of the corresponding cylinder 110. When the telescopic drive component 222 is activated, it drives the moving rod 221 to reciprocate linearly along the arrangement direction of each of the pumping mechanisms 100.

[0039] As a preferred embodiment, please refer to Figure 1The transmission assembly 230 includes a first rack 231, a second rack 232, a transmission shaft 233, a first gear 234, and a second gear 235. The first rack 231 is parallel to and fixedly connected to the moving rod 221. The second rack 232 is parallel to the cylinder 110, and one end of the second rack 232 is fixedly connected to the second connecting plate 210. The transmission shaft 233 is perpendicular to both the first rack 231 and the second rack 232. The first gear 234 and the second gear 235 are coaxially fixedly connected to both ends of the transmission shaft 233. The first gear 234 meshes with the first rack 231, and the second gear 235 meshes with the second rack 232. When a pumping mechanism 100 needs to be activated, the corresponding second connecting plate 210 is detachably connected to the corresponding first connecting plate 123. The telescopic drive 222 is activated, and the telescopic drive 222 drives the moving rod 221 along each... The first rack 231 moves reciprocally in the direction of the arrangement of each of the pumping mechanisms 100, thereby driving the first gear 234 to rotate in the forward or reverse direction, and driving the transmission shaft 233 to rotate in the forward or reverse direction. Then, it drives the second gear 235 to rotate in the forward or reverse direction, thereby driving the second rack 232 to move reciprocally along the axial direction of the cylinder 110. Then, it drives the second connecting plate 210 to move reciprocally along the axial direction of the cylinder 110, thereby enabling the first connecting plate 123 to move reciprocally along the axial direction of the cylinder 110. This, in turn, drives the piston 121 to move reciprocally along the axial direction of the cylinder 110 via the connecting rod 122. During the reciprocating movement of the piston 121 along the axial direction of the cylinder 110, the hazardous wastewater in the water tank can be pumped into the target container, thereby realizing the function of pumping out the hazardous wastewater in the water tank.

[0040] As a preferred embodiment, please refer to Figure 1 The hazardous wastewater pumping system further includes a frame 300, the movable rod 221 is slidably connected to the frame 300, and each of the drive shafts 233 is rotatably connected to the frame 300. The frame 300 can support the movable rod 221 and the drive shafts 233.

[0041] To better understand this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of this utility model will be described in detail below:

[0042] In use, the inlet ends of each of the first pipe bodies 131 are connected to each of the corresponding water tanks, and the outlet ends of each of the second pipe bodies 131 are connected to the target container. The number of water tanks containing hazardous wastewater to be pumped determines which pumping mechanism 100 needs to be activated. When a pumping mechanism 100 needs to be activated, the corresponding second connecting plate 210 is detachably connected to the corresponding first connecting plate 123. The telescopic drive 222 is activated, driving the moving rod 221 to reciprocate linearly along the arrangement direction of each pumping mechanism 100. The corresponding first rack 231 will also reciprocate linearly along the arrangement direction of each pumping mechanism 100, thereby driving... The corresponding first gear 234 rotates in either the forward or reverse direction, driving the corresponding transmission shaft 233 to rotate in either the forward or reverse direction. This, in turn, drives the corresponding second gear 235 to rotate in either the forward or reverse direction, thereby causing the corresponding second rack 232 to reciprocate along the axial direction of the corresponding cylinder 110. This, in turn, causes the corresponding second connecting disc 210 to reciprocate along the axial direction of the corresponding cylinder 110. This allows the corresponding first connecting disc 123 to reciprocate along the axial direction of the corresponding cylinder 110, which in turn drives the corresponding piston 121 to reciprocate along the axial direction of the corresponding cylinder 110 via the corresponding connecting rod 122. During the reciprocating motion of the piston 121 along the axial direction of the cylinder 110, it can... The hazardous wastewater in the water tank is pumped into the target container, thus realizing the function of pumping out the hazardous wastewater in the water tank. During the pumping operation, the piston 121 first moves upward. At this time, the space below the piston 121 increases, and the pressure decreases. The pressure in the space below the piston 121 is less than the external pressure. The first valve plate 134 moves away from the first mounting ring 132, and the second valve plate 134 is attached to the orifice of the second mounting ring 132. The first pipe 131 is in a conductive state, and the second pipe 131 is in a cut-off state. The hazardous wastewater in the water tank is forced into the first pipe 131 under atmospheric pressure and then into the space below the piston 121. The piston 121 then moves downward. As the space below the piston 121 decreases, the pressure increases, making the pressure in the space below the piston 121 greater than the external pressure. The first valve plate 134 is fitted against the orifice of the first mounting ring 132, while the second valve plate 134 is moved away from the second mounting ring 132. The first pipe body 131 is in a cut-off state, while the second pipe body 131 is in a conductive state. The hazardous wastewater in the space below the piston 121 enters the second pipe body 131 and is discharged into the target container. When only one tank of hazardous wastewater needs to be pumped out, the corresponding second connecting plate 210 can be detachably connected to the corresponding first connecting plate 123, and the piston 121 is driven by the driving mechanism 200.Alternatively, the drive assembly 140 can be detachably connected to the piston assembly 120, driving the piston assembly 120 to reciprocate along the axial direction of the cylinder 110 via the drive assembly 140. In this hazardous wastewater pumping system, the pumping mechanism 100 can be used individually or in combination, driven by a single driver, offering strong applicability. The system allows for the selection of pumping mechanisms 100 based on the number of tanks containing hazardous wastewater to be pumped. For multiple pumping mechanisms 100 used in combination, only one driver is required, avoiding the problem of multiple manual pumps requiring multiple operators when multiple pumps are used together, thus reducing labor costs and improving the efficiency of pumping wastewater.

[0043] The hazardous wastewater pumping and drainage system provided by this utility model has the following beneficial effects:

[0044] (1) In this hazardous wastewater pumping system, when the pumping mechanism 100 is used alone, the sliding shaft 146 abuts into the sliding groove 1241 under the action of the elastic member 147, thereby achieving a sliding connection with the sliding rod 124 of the piston assembly 120. Then, manually rotating the rocker arm 148 can drive the drive shaft 142 to rotate. Since the flower rod 143 is connected to the flower hole on the drive shaft 142, the flower rod 143 can only move along the axial direction of the drive shaft 142 and cannot rotate relative to the drive shaft 142. When the drive shaft 142 rotates, the flower rod 143 will rotate synchronously, thereby driving the rotating disk 144 and the sliding shaft 146 to rotate synchronously. 6. Due to the restriction of the sliding groove 1241 on the sliding rod 124, when the sliding shaft 146 rotates, the sliding rod 124 will move up and down, thereby causing the connecting rod 122 to move up and down, which in turn drives the piston 121 to move up and down. When multiple pumping mechanisms 100 need to be used together, the flower rod 143 is pulled outward to move the sliding shaft 146 out of the sliding groove 1241. At this time, the driving assembly 140 is separated from the sliding rod 124 of the piston assembly 120. Then, the connecting part of the driving mechanism 200 is detachably connected to the corresponding second connecting plate 210 to complete the assembly of the driving mechanism 200 and the piston assembly 120 of the pumping mechanism 100.

[0045] (2) In this hazardous wastewater pumping system, the pumping mechanism 100 can be used alone or multiple units can be used together and driven by a single driver, making it highly adaptable;

[0046] (3) In this hazardous wastewater pumping system, the number of pumping mechanisms 100 to be activated can be determined according to the actual number of water tanks containing hazardous wastewater to be pumped. For the combined use of multiple pumping mechanisms 100, only one driver is used to drive them, avoiding the problem that multiple traditional hand-cranked pumps cannot be driven by one driver and require multiple operators when multiple pumps are used together, thereby reducing labor costs and improving the efficiency of pumping wastewater.
