Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump technology, specifically a mobile diaphragm pump that avoids diaphragm damage. Background Technology

[0002] In the chemical industry, due to the unique working environment and the need to discharge and recover materials from pipelines and equipment during operations, mobile diaphragm pumps offer the advantage of being able to move freely for material recovery and transportation. However, due to the special nature of the diaphragm in the internal structure of mobile diaphragm pumps, the entry of foreign matter can cause diaphragm damage, thus affecting the pump's operating performance. Therefore, a mobile diaphragm pump designed to prevent diaphragm damage is provided. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a mobile diaphragm pump that avoids diaphragm damage, thereby solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile diaphragm pump that avoids diaphragm damage, comprising a pneumatic diaphragm pump, wherein the inlet of the pneumatic diaphragm pump is connected to a filter via a connecting pipe, the filter is connected to an inlet pipe and an outlet pipe, the outlet of the pneumatic diaphragm pump is connected to an outlet pipe, the pneumatic diaphragm pump is also connected to a power air source pipe, the top of the filter is connected to a pressure relief pipe, and a valve F is installed on the pressure relief pipe.

[0005] As a preferred embodiment of this utility model, a valve E is installed on the connecting pipe.

[0006] As a preferred embodiment of this utility model, a valve D is installed on the power air source pipeline.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This pneumatic diaphragm pump is equipped with a filter at the inlet to filter materials containing impurities, preventing impurities from entering the pump and damaging the diaphragm, thus extending the pump's service life and ensuring optimal performance. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] In the diagram: 1. Pneumatic diaphragm pump; 2. Filter; 3. Power air source pipeline; 301. Valve D; 4. Discharge pipeline; 401. Valve C; 5. Feed pipeline; 501. Valve A; 6. Discharge pipeline; 601. Valve B; 7. Connecting pipeline; 701. Valve E. Detailed Implementation

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0015] Example: Please refer to Figure 1 This utility model provides a technical solution: a mobile diaphragm pump that avoids diaphragm damage, including a pneumatic diaphragm pump 1. The inlet of the pneumatic diaphragm pump 1 is connected to a filter 2 via a connecting pipe 7. The filter 2 is connected to an inlet pipe 5 and an outlet pipe 6. The outlet of the pneumatic diaphragm pump 1 is connected to an outlet pipe 4. The pneumatic diaphragm pump 1 is also connected to a power air source pipe 3. The top of the filter 2 is connected to a pressure relief pipe, and a valve F is installed on the pressure relief pipe.

[0016] A valve E701 is installed on the connecting pipe 7 to control the raw material entering the pneumatic diaphragm pump 1; a valve D301 is installed on the power air source pipe 3 to control the power air source entering the pneumatic diaphragm pump 1; a valve A501 is installed on the feed pipe 5 to control the raw material entering the filter 2; a valve B601 is installed on the discharge pipe 6 to control the discharge of filtered impurities; and a valve C401 is installed on the discharge pipe 4 to control the discharge of raw materials.

[0017] A portable diaphragm pump designed to prevent diaphragm rupture is used by closing valves F and B601 on the filter depressurization pipe, opening valve A501 on the feed pipe 5, valve E701 on the connecting pipe 7, and valve C401 on the discharge pipe 4. After the pump inlet and outlet flows are connected, a power source (compressed air or nitrogen) is connected. Then, valve A501 is slowly opened until the opening of valve A501 allows the pneumatic diaphragm pump to operate normally.

[0018] The raw material enters the filter 2 through the feed pipe 5 for filtration. After filtration, the raw material enters the pneumatic diaphragm pump 1 through the connecting pipe 7. The filter 2 is used to filter out impurities in the raw material to prevent impurities from entering the pump cavity and damaging the diaphragm when conveying materials containing impurities. Therefore, a filter is added at the pump inlet to prevent damage to the diaphragm.

[0019] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
