Description

Technical Field

[0001] This utility model relates to the field of pumping equipment technology, and in particular to a piston industrial pump that does not accumulate material. Background Technology

[0002] Liquid transport plays a vital role in industrial processing. Liquid materials have a wide viscosity range. Low-viscosity water and oil are generally transported using flow pumps, relying on the high-speed rotating impeller to continuously transfer energy to the liquid surface to complete the transport. However, for high-viscosity fluids, such as industrial adhesives, construction adhesives, jams, and industrial greases, conventional pumps cannot handle their poor flowability, requiring pumping equipment with strong suction capabilities. Reciprocating positive displacement pumps, relying on the reciprocating motion of a plunger within the pump cylinder, can quantitatively draw in and discharge liquids, making them suitable for transporting viscous materials with low flow rates and high pressures.

[0003] However, existing devices do not solve the problems of inconvenience in inspecting internal valve disc damage, easy material accumulation at the discharge position, inconvenience in disassembling the discharge end affecting maintenance efficiency, and the viscous medium remaining in the pipeline after shutdown gradually dehydrates and solidifies, forming hard scale, which causes the piston industrial pump to jam or the flow channel to become blocked during the next startup. Therefore, this application provides a piston industrial pump without material accumulation to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a piston industrial pump without material accumulation, so as to solve the problem that existing piston industrial pumps are not convenient for checking the damage of internal valve discs and are prone to material accumulation at the discharge position.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A non-accumulating piston industrial pump includes a frame, an inlet / outlet assembly mounted on the upper surface of the frame, a cleaning assembly mounted on one side of the frame, a pushing hydraulic device fixedly connected to the upper surface of the frame, a water tank mounted on the upper surface of the frame, a support rod mounted on one side of the water tank, a cylinder mounted on one side of the water tank, a bracket mounted on the upper surface of the frame, and a control cabinet mounted on one side of the bracket.

[0007] Optionally, the feeding and discharging assembly includes a three-way valve seat, a feeding hydraulic device, a hopper bend, a pressure sensor, an inspection window, a hinge, a discharge valve seat, a discharge hydraulic device, and a discharge nozzle. The feeding hydraulic device is installed on one side of the three-way valve seat, and the hopper bend is installed on the other side of the three-way valve seat. A pressure sensor is provided on the upper surface of the three-way valve seat. An inspection window is installed on one side of the three-way valve seat. A hinge is provided on one side of the three-way valve seat. A discharge valve seat is provided on one side of the hinge. A discharge hydraulic device is installed on one side of the discharge valve seat. A discharge nozzle is installed on the lower surface of the discharge valve seat.

[0008] Optionally, the number of inspection windows is two, with the two inspection windows located on both sides of the three-way valve seat near the middle.

[0009] Optionally, one end of the feeding hydraulic device is provided with a feeding valve, and one end of the discharging hydraulic device is provided with a discharging valve.

[0010] Optionally, the number of hinges is two, with the two hinges located on both sides of the three-way valve seat near the lower part.

[0011] Optionally, the number of pressure sensors is two, with the two pressure sensors located on the upper surface of the three-way valve seat near both sides.

[0012] Optionally, the cleaning assembly includes a cleaning solution tank, a water pump, a supply pipe, a connector, a collection tank, a collection pipe, and a connector. The water pump is inserted into one side of the cleaning solution tank, the supply pipe is inserted into one end of the water pump, and the connector is fixedly connected to one end of the supply pipe. The collection tank is installed on the upper surface of the cleaning solution tank, the collection pipe is inserted into the upper surface of the collection tank, and the connector is inserted into one end of the collection pipe.

[0014] Optionally, the water tank has an inlet located near the top on one side and an outlet located near the bottom on the other side.

[0015] Optionally, the water tank is located on the upper surface of the frame near the middle, and the support is located on the upper surface of the frame near the material pushing hydraulic device.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, an inspection window is provided, allowing for convenient inspection of the internal valve disc for damage. A pressure sensor at the top enables real-time monitoring of the discharge end pressure. The bottom of the three-way valve seat is flush with the discharge valve seat, eliminating material accumulation points. The discharge nozzle is located at the bottom of the discharge valve seat, preventing material accumulation and ensuring smooth discharge. Valve disc maintenance is achieved by disassembling the corresponding flange and directly removing the valve disc for inspection.

[0018] By setting up a cleaning assembly, connecting and fixing the connector to the discharge nozzle, and then connecting and fixing the connector to the hopper bend near the cleaning assembly, the feeding hydraulic device on the side away from the cleaning assembly is driven to close the feeding valve. Simultaneously, the discharging hydraulic device on the side away from the cleaning assembly is driven to close the discharging valve. Then, a water pump pumps the cleaning fluid from the cleaning fluid tank into the discharge nozzle through the supply pipe, thus rinsing the inside of the inlet and outlet assemblies. The rinsed wastewater is discharged through the hopper bend into the connector, and then through the collection pipe into the collection tank. After cleaning, the connector is connected and fixed to the hopper bend on the side away from the cleaning assembly, and the feeding hydraulic device on the side near the cleaning assembly is driven to close the discharge valve. The feed valve is closed, and the discharge hydraulic device near the cleaning component is driven to close the discharge valve. Then, the cleaning liquid in the cleaning liquid tank is discharged into the discharge nozzle through the supply pipe by the water pump, which can flush the inside of the feed and discharge components. The flushed wastewater is discharged into the connector through the hopper bend pipe, and then into the collection box through the collection pipe. This completes the cleaning of the feed and discharge components, reducing the possibility that the viscous medium remaining in the pipeline after shutdown will gradually dehydrate and solidify, forming hard scale, which may cause the piston industrial pump to jam or the flow channel to block during the next startup. It achieves the effect of reverse flushing of the inside of the feed and discharge components, breaking the solidified layer through the shearing force of the reverse water flow, and maintaining the flow of the pipeline.

[0033] like Figures 1-4As shown, an embodiment of this utility model provides a non-accumulating piston industrial pump, including a frame 1. An inlet / outlet assembly 2 is mounted on the upper surface of the frame 1. The inlet / outlet assembly 2 includes a three-way valve seat 201, an inlet hydraulic device 202, a hopper bend 203, a pressure sensor 204, an inspection window 205, a hinge 206, an outlet valve seat 207, an outlet hydraulic device 208, and an outlet nozzle 209. The inlet hydraulic device 202 is mounted on one side of the three-way valve seat 201. On the other side of 201, a hopper bend 203 is installed. A pressure sensor 204 is installed on the upper surface of the three-way valve seat 201. An inspection window 205 is installed on one side of the three-way valve seat 201. A hinge 206 is installed on one side of the three-way valve seat 201. A discharge valve seat 207 is installed on one side of the hinge 206. A discharge hydraulic device 208 is installed on one side of the discharge valve seat 207. A discharge nozzle 209 is installed on the lower surface of the discharge valve seat 207. There are two inspection windows 205. The two inspection windows 205 are respectively... Located near the middle on both sides of the three-way valve seat 201, the feeding hydraulic device 202 has a feeding valve at one end, and the discharging hydraulic device 208 has a discharging valve at one end. There are two hinges 206, which are located near the lower part on both sides of the three-way valve seat 201. There are two pressure sensors 204, which are located near the sides on the upper surface of the three-way valve seat 201. A cleaning component 3 is installed on one side of the frame 1. A pushing hydraulic device 4 is fixedly connected to the upper surface of the frame 1. A water tank 5 is installed on the upper surface of the frame 1. A water inlet is located near the upper part on one side of the water tank 5, and a water outlet is located near the lower part on one side of the water tank 5.

[0034] By placing the equipment in the required installation position and connecting the hopper bend 203 to the material placement equipment, the feeding hydraulic device 202 near the cleaning component 3 is driven to open the feeding valve. Simultaneously, the pushing hydraulic device 4 near the cleaning component 3 is driven, causing the piston inside the pushing hydraulic device 4 to move towards the tail end, thereby drawing material into the cylinder 7 near the cleaning component 3. After the piston inside the pushing hydraulic device 4 reaches its tail end, the feeding valve is closed by driving the feeding hydraulic device 202 near the cleaning component 3. Then, the discharge valve is opened by driving the discharge hydraulic device 208 near the cleaning component 3. Simultaneously, the piston inside the pushing hydraulic device 4 near the cleaning component 3 moves towards the inlet / outlet component 2, discharging the material from the discharge nozzle 209. Simultaneously, the material is discharged while the cylinder 7 near the cleaning component 3 is being driven. The feeding hydraulic device 202 on the side away from the cleaning component 3 is activated to open the feeding valve. At the same time, the pushing hydraulic device 4 on the side away from the cleaning component 3 is driven to move the piston inside the pushing hydraulic device 4 to the tail end, thereby sucking the material into the cylinder 7 on the side away from the cleaning component 3. After the piston inside the pushing hydraulic device 4 moves to the tail end, the feeding valve is closed by activating the feeding hydraulic device 202 on the side away from the cleaning component 3. Then, the discharging hydraulic device 208 on the side away from the cleaning component 3 is activated to open the discharging valve. At the same time, the piston inside the pushing hydraulic device 4 on the side away from the cleaning component 3 is moved towards the feeding / discharging component 2 by activating the pushing hydraulic device 4 on the side away from the cleaning component 3, so that the material can be discharged from the discharge nozzle 209. Repeating the above operation can complete the alternating feeding and discharging of materials. Cooling the piston inside the pushing hydraulic device 4 can be cooled by pouring coolant into the water tank 5.

[0035] The inspection window 205 allows for easy inspection of the internal valve disc for damage. The pressure sensor 204 at the top can monitor the pressure at the discharge end in real time. The bottom of the three-way valve seat 201 is flush with the discharge valve seat 207 without any material accumulation points. The discharge nozzle 209 is located at the bottom of the discharge valve seat 207, and there are no material accumulation points at the discharge nozzle 209, ensuring smooth discharge. For valve disc maintenance, the corresponding flange can be disassembled, and the valve disc can be directly pulled out for maintenance. The discharge valve seat 207 and the three-way valve seat 201 are connected by a hinge 206, which facilitates disassembly for maintenance. This reduces the problems of existing devices, such as inconvenience in inspecting internal valve disc damage, easy material accumulation at the discharge position, and inconvenience in disassembling the discharge end affecting maintenance efficiency. It achieves the effect of convenient inspection of internal valve disc damage through the inspection window 205, the bottom of the three-way valve seat 201 being flush with the discharge valve seat 207 without any material accumulation points, and the easy removal of the discharge valve seat 207 for maintenance due to the hinge 206 connection.

[0036] like Figure 1 and Figure 5As shown, the cleaning component 3 includes a cleaning liquid tank 301, a water pump 302, a supply pipe 303, a connector 304, a collection tank 305, a collection pipe 306, and a connector 307. The water pump 302 is inserted into one side of the cleaning liquid tank 301, and the supply pipe 303 is inserted into one end of the water pump 302. The connector 304 is fixedly connected to one end of the supply pipe 303. The collection tank 305 is installed on the upper surface of the cleaning liquid tank 301, and the collection pipe 306 is inserted into the upper surface of the collection tank 305. The connector 307 is inserted into one end of the collection pipe 306. The water pump 302 is located on one side of the cleaning liquid tank 301 near the lower part, and the connector 304 and the connector 307 are both located on the upper part of the collection tank 305.

[0037] By connecting and fixing the connector 304 to the discharge nozzle 209, and then connecting and fixing the connector 307 to the hopper bend 203 near the cleaning component 3, the feeding hydraulic device 202 on the side away from the cleaning component 3 is driven to close the feeding valve. At the same time, by driving the discharge hydraulic device 208 on the side away from the cleaning component 3, the discharge valve is closed. Then, the cleaning liquid inside the cleaning liquid tank 301 is discharged into the discharge nozzle 209 through the supply pipe 303 by the water pump 302, thus rinsing the inside of the inlet and outlet component 2. The wastewater after rinsing is discharged into the connector 307 through the hopper bend 203, and then into the collection box 305 through the collection pipe 306. After cleaning, the connector 307 is connected and fixed to the hopper bend 203 on the side away from the cleaning component 3, and the feeding hydraulic device 202 on the side near the cleaning component 3 is driven to close the discharge valve. The hydraulic device 202 closes the feed valve and simultaneously drives the discharge hydraulic device 208 near the cleaning component 3 to close the discharge valve. Then, the water pump 302 discharges the cleaning liquid inside the cleaning liquid tank 301 into the discharge nozzle 209 through the supply pipe 303, thus rinsing the inside of the feed assembly 2. The flushed wastewater is discharged into the connector 307 through the hopper bend pipe 203 and then into the collection box 305 through the collection pipe 306. This completes the cleaning of the feed assembly 2, reducing the possibility that the viscous medium remaining in the pipeline after shutdown will gradually dehydrate and solidify, forming hard scale, which could cause the piston industrial pump to jam or the flow channel to become blocked during the next startup. This achieves the effect of reverse flushing of the inside of the feed assembly 2, breaking the solidified layer through the shearing force of the reverse water flow, and maintaining the flowability of the pipeline.

[0038] The working principle of the technical solution provided by this utility model is as follows: By placing the equipment in the required installation position, the hopper bend 203 is connected to the material placement equipment to be conveyed. By driving the feeding hydraulic device 202 near the cleaning component 3, the feeding valve is opened. At the same time, by driving the pushing hydraulic device 4 near the cleaning component 3, the piston inside the pushing hydraulic device 4 moves to the tail end, thereby sucking the material into the cylinder 7 near the cleaning component 3. After the piston inside the pushing hydraulic device 4 moves to the tail end, the feeding valve is closed by driving the feeding hydraulic device 202 near the cleaning component 3. Then, the discharging hydraulic device 208 near the cleaning component 3 is driven to open the discharging valve. The pushing hydraulic device 4 on one side of the cleaning component 3 moves the piston inside the pushing hydraulic device 4 towards the inlet / outlet component 2, thus discharging the material from the outlet 209. Simultaneously, it drives the inlet hydraulic device 202 on the side away from the cleaning component 3, opening the inlet valve. At the same time, it drives the pushing hydraulic device 4 on the side away from the cleaning component 3, causing the piston inside the pushing hydraulic device 4 to move towards the tail end, thereby drawing the material into the cylinder 7 on the side away from the cleaning component 3. After the piston inside the pushing hydraulic device 4 reaches the tail end, it drives the inlet hydraulic device 202 on the side away from the cleaning component 3, closing the inlet valve. Then, it drives the outlet hydraulic device 208 on the side away from the cleaning component 3, opening the outlet valve. Simultaneously, it drives the... The pushing hydraulic device 4, located on the side away from the cleaning component 3, moves the piston inside the pushing hydraulic device 4 towards the feeding / discharging component 2, thus discharging the material through the discharge nozzle 209. Repeating this operation completes alternating material feeding and discharging. The inspection window 205 allows for easy inspection of the internal valve disc for damage. The pressure sensor 204 at the top can monitor the pressure at the discharge end in real time. The bottom of the three-way valve seat 201 is flush with the discharge valve seat 207, with no material accumulation points. The discharge nozzle 209 is located at the bottom of the discharge valve seat 207, ensuring smooth material discharge without any accumulation points. For valve disc maintenance, the corresponding flange can be disassembled, and the valve disc can be directly pulled out for inspection. The discharge valve seat 207 and the three-way valve seat 201 are connected by a hinge 206, facilitating disassembly for maintenance. By connecting and fixing the connector 304 to the discharge nozzle 209, and then connecting and fixing the connector 307 to the hopper bend 203 near the cleaning component 3, the feeding hydraulic device 202 on the side away from the cleaning component 3 is driven to close the feeding valve. At the same time, by driving the discharge hydraulic device 208 on the side away from the cleaning component 3, the discharge valve is closed. Then, the cleaning liquid inside the cleaning liquid tank 301 is discharged into the discharge nozzle 209 through the supply pipe 303 by the water pump 302, thus rinsing the inside of the inlet and outlet component 2. The wastewater after rinsing is discharged into the connector 307 through the hopper bend 203, and then into the collection box 305 through the collection pipe 306. After cleaning, the connector 307 is connected and fixed to the hopper bend 203 on the side away from the cleaning component 3.The feeding hydraulic device 202, located near the cleaning component 3, is activated to close the feeding valve. Simultaneously, the discharging hydraulic device 208, also located near the cleaning component 3, is activated to close the discharging valve. Then, the cleaning fluid in the cleaning fluid tank 301 is pumped through the supply pipe 303 into the discharge nozzle 209 via the water pump 302. This flushes the inside of the feeding and discharging component 2. The flushed wastewater is discharged through the hopper bend pipe 203 into the connector 307, and then through the collection pipe 306 into the collection box 305, thus completing the cleaning of the feeding and discharging component 2.
