Description

Technical Field

[0001] This utility model relates to the technical field of material recycling devices, and more specifically, to a centrifugal pump material filling pump exhaust recycling device. Background Technology

[0002] Centrifugal pumps, as key equipment in industrial fluid transfer systems, are widely used in various industries such as chemical, petroleum, and pharmaceutical. During the operation of centrifugal pumps, priming and venting are usually required to ensure that the pump body is filled with liquid and to expel internal air. This prevents cavitation and ensures the normal operation and efficiency of the pump. The materials generated during this process need to be properly handled to prevent environmental pollution or safety hazards.

[0003] In the existing technology, the specific implementation of centrifugal pump filling and venting mainly includes the following two situations: one is to simply place a recycling bin below the centrifugal pump filling and venting pipe, so that the material generated during the venting process can be directly discharged into the recycling bin. This operation has the risk of material splashing. The other way is to directly connect the outlet of the venting pipe to a recycling bin, and then collect the recycling bin for further processing. That is, the material in the recycling bin cannot be directly processed, and new safety risks cannot be avoided in the multi-step operation.

[0004] Therefore, this application is hereby submitted. Utility Model Content

[0030] The following describes in detail the overall structure, working principle, and technical effects of the centrifugal pump filling and exhaust material recovery device 100 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0031] First Embodiment

[0032] Please refer to Figure 1 The centrifugal pump filling and exhaust material recovery device 100 provided in this embodiment includes a recovery tank 200, a centrifugal pump 300, a filter 400, a storage tank (not shown in the figure) and a tank truck (not shown in the figure).

[0033] The recycling tank 200 is used to recycle similar materials. Its body has a recycling port 202, a first discharge port 204, an exhaust port 201, and an inflation port 203. It should be noted that the recycling tank 200 is placed vertically in this embodiment. The recycling port 202, exhaust port 201, and inflation port 203 are located at the top of the recycling tank 200, and the first discharge port 204 is located at the bottom of the recycling tank 200. In other embodiments, the specific positions of the recycling port 202, exhaust port 201, and inflation port 203 can be reasonably adjusted according to the actual placement of the recycling tank 200.

[0034] The recovery port 202 is connected to the second discharge port 301 of the centrifugal pump 300, and a fourth valve 208 and a sixth valve 210 are installed on the pipeline connected to the recovery port 202, which is beneficial for regulating the flow of materials and the pipeline pressure. It should be noted that in this embodiment, a pressure monitoring device connection port 600 is provided at the end of the sixth valve 210 away from the fourth valve 208 for monitoring the pipeline pressure.

[0035] The exhaust port 201 is directly located on the tank body of the recycling tank 200. It is used to release pressure from the recycling tank 200, ensuring stable internal pressure and safe operation. In addition, the exhaust port 201 is also connected to a tail gas treatment device, which facilitates further treatment of the gas generated during the material recycling process and avoids environmental pollution. A second valve 206 is installed on the pipe connected to the exhaust port 201.

[0036] The filling port 203 can fill the recovery tank 200 with gas as needed, such as to meet the requirements of high oxygen content, nitrogen, or other gases. A first valve 205 is installed on the pipe connected to the filling port 203.

[0037] The first discharge port 204 is connected to the inlet 302 of the centrifugal pump 300, and the vertical height of the first discharge port 204 is higher than the vertical height of the inlet 302 and the vertical height of the pipe connected to the inlet 302. This arrangement is advantageous for using the liquid level difference to return the material in the recovery tank 200 to the pipe upstream of the inlet 302 of the centrifugal pump 300.

[0038] In this embodiment, a level gauge 500 with a sight glass is installed on the tank body of the recycling tank 200, which is beneficial for real-time monitoring of the amount of material in the recycling tank 200 and avoiding the risk of overfilling. In other embodiments, a level alarm can be installed according to actual needs, or the level gauge 500 with a sight glass and the level alarm can be used together to detect the material level in the recycling tank 200.

[0039] It should be noted that in this embodiment, the level gauge 500 is installed in the middle of the side wall of the recovery tank 200, and its distance from the top and bottom of the tank is equal. The overall length of the level gauge 500 is 4 / 5 of the height of the recovery tank 200. In other embodiments, the size of the level gauge 500 can be reasonably designed according to whether the actual recovery tank 200 is horizontal or vertical.

[0040] The centrifugal pump 300 has an inlet 302 and a second outlet 301. Upstream of the inlet 302, a filter 400 is installed on the pipe connected to the inlet 302. The inlet 302 is connected to the first outlet 204 of the recovery tank 200. A third valve 207 is installed on the pipe connecting the filter 400 and the first outlet 204.

[0041] A fifth valve 209 is installed on the pipe connected to the second discharge port 301.

[0042] It should be noted that in this embodiment, the first discharge port 204 of the recycling tank 200 is set at the front end of the filter 400, which can directly recycle materials and filter the materials entering the recycling tank 200, so as to avoid impurities in the materials from causing damage to the equipment and affecting the service life of the equipment.

[0043] In other embodiments, the filter 400 may be removed depending on the material being processed.

[0044] In this embodiment, the recycling tank 200 is connected to the centrifugal pump 300, which can greatly reduce the risks of material splashing, environmental pollution, personnel poisoning, fire, and explosion; meet the material recycling needs, reduce raw material loss, and reduce the company's hazardous waste treatment costs.

[0045] The storage tank is connected to the second discharge port 301 and also to the tank truck. In this embodiment, after the centrifugal pump filling and exhaust material recovery device 100 is installed, the material generated by the exhaust gas enters the recovery tank 200 directly through the pipeline. The material is then recovered to the process pipeline through the first material outlet of the recovery tank 200 and then transported to the second material outlet, and transported to the storage tank together with the material from the tank truck.

[0046] Please refer to Figure 1 The working principle of the centrifugal pump filling and exhaust material recovery device 100 is as follows:

[0047] During the priming operation of centrifugal pump 300, open valves 210, 208, and 206 to perform priming. After priming, close valves 208 and 206 and start centrifugal pump 300. After centrifugal pump 300 is emptied and the pipeline before pump 300 is half full of material, open valves 208 and 207 to use the liquid level difference to return the material from recovery tank 200 to the pipeline before pump inlet 302 of centrifugal pump 300. Then close valves 208 and 207 and recover the material directly into the process pipeline when the pump is started again.

[0048] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
