Description

Technical Field

[0001] This utility model relates to the field of feed pump technology, specifically a dual-cylinder single-feed pump body structure for the particulate matter abrasion industry. Background Technology

[0002] Currently, the abrasive processing industry primarily uses dual-cylinder single-feed equipment, as shown in the attached image. Figure 1 As shown, this device can prevent piston rod wear in the material and also eliminate the risk of hydraulic oil leaking into the material at the cylinder guide sleeve. However, if large particles enter the working cylinder, the long-term reciprocating motion of the piston head will cause wear to the working cylinder, damage the seals, and render the equipment unusable, indicating room for improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a dual-cylinder single-feed pump body structure that reduces material wear on the working cylinder and extends the overall service life of the pump body.

[0004] To achieve the above objectives, this utility model provides a dual-cylinder single-feed pump body structure for the particulate matter abrasion industry, which adopts the following technical solution: A dual-cylinder single-feed pump body structure for the particulate abrasion industry includes a frame, on which a left working cylinder and a right working cylinder are mounted. The left and right working cylinders are respectively connected to a second left and a second right flow pipe via a first left flow pipe and a first right flow pipe, respectively. The lower ends of the second left and second right flow pipes are respectively connected to a third left and a third right flow pipe. The two ends of the third left and third right flow pipes are respectively connected to a discharge pipe and a feed pipe. The feed pipe is provided with a discharge port and a feed port respectively. The third left flow pipe, the third right flow pipe and the discharge pipe are respectively provided with a left discharge check valve and a right discharge check valve. The third left flow pipe, the third right flow pipe and the feed pipe are respectively provided with a left feed check valve and a right feed check valve. The diameter of the second left flow pipe is larger than the diameter of the first left flow pipe and the third left flow pipe. The diameter of the second right flow pipe is larger than the diameter of the first right flow pipe and the third right left flow pipe.

[0005] A further improvement of the dual-cylinder single-feed pump body structure for the particulate abrasion industry of this utility model is that a filter device is provided at the upper part of both the second left overflow pipe and the second right overflow pipe.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This invention adds a large-diameter flow pipe between the working cylinder and the conventional flow pipe, and is equipped with a filter device, so that large particles in the material will not enter the working cylinder, thereby reducing the wear of the material on the inside of the working cylinder and extending its service life.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0010] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0012] like Figure 2As shown, a dual-cylinder single-feed pump body structure for the particulate abrasion industry includes a frame 10, on which a left working cylinder 1 and a right working cylinder 2 are mounted. The left and right working cylinders are connected to a second left flow pipe 4 and a second right flow pipe respectively via a first left flow pipe 3 and a first right flow pipe. The lower ends of the second left and second right flow pipes are connected to a third left flow pipe 5 and a third right flow pipe respectively. The two ends of the third left and third right flow pipes are connected to a discharge pipe 9 and a feed pipe 7 respectively. The discharge pipe and the feed pipe are respectively provided with a discharge port and a feed port. The third left flow pipe and the third right flow pipe are respectively provided with a left discharge check valve and a right discharge check valve 8 between them and the discharge pipe. The third left flow pipe and the third right flow pipe are respectively provided with a left feed check valve 5 and a right feed check valve 5 between them and the feed pipe. The diameter of the second left flow pipe is larger than the diameter of the first left flow pipe and the third left flow pipe. The diameter of the second right flow pipe is larger than the diameter of the first right flow pipe and the third right left flow pipe.

[0013] Both the second left and second right overflow pipes are equipped with filter devices 11 at their upper parts. The filter devices can be filter screen structures to prevent large particles in the material from entering the working cylinder.

[0014] The working principle of this invention is as follows: When the equipment starts running, particulate material is drawn in through the feed pipe and enters the large-diameter flow pipes (the second left and right flow pipes). Due to the excessively high flow velocity in the small-diameter pipes (the third left and right flow pipes), the flow velocity decreases upon entering the large-diameter pipe, keeping the particles in a suspended state and preventing them from rapidly impacting the filter device. The filter device then filters out large particles, preventing them from entering the working cylinder. When the piston head in the working cylinder reciprocates and discharges material, the material passes through the large-diameter flow pipe again, and the previously stored large particles are discharged through the small-diameter flow pipe and the discharge check valve. This structure ensures that large particles do not enter the working cylinder, thereby reducing wear on the cylinder's interior and extending its service life.

[0015] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
