Description

Technical Field

[0001] This utility model belongs to the technical field of mining conveying equipment, specifically relating to a mobile pneumatic diaphragm pump for mining. Background Technology

[0002] In mining operations such as coal mining and metal mining, underground drainage, slurry transportation, and sludge cleaning are core aspects of ensuring production safety and continuity. Mining pneumatic diaphragm pumps have become key equipment for underground fluid transportation due to their advantages such as simple structure, no electric drive, and ability to transport media containing solid particles.

[0003] Patent application number 202421340682.6 discloses a portable pneumatic diaphragm pump for mining. This utility model relates to a portable pneumatic diaphragm pump for mining, comprising a movable plate and a diaphragm pump body. The movable plate has an internal movable adjustment mechanism and a top pipe fixing assembly for the diaphragm pump body. The movable adjustment mechanism includes the diaphragm pump body fixedly connected to the top of the movable plate, and two fixed blocks fixedly connected to the bottom of the movable plate. Two sliding blocks are slidably connected inside the fixed blocks. This portable pneumatic diaphragm pump for mining allows for the rotation of a bidirectional screw, causing the threaded sleeve to move the displacement block within the fixed block. This facilitates the contact between the pushing block and the pushing groove on the sliding block, allowing the sliding block to move vertically up and down within the fixed block. When the universal wheels on the sliding block extend to the outside of the fixed block, they provide support, preventing the fixed block from contacting the ground and reducing friction. This makes the diaphragm pump body easy to move and effectively improves the practicality of the device.

[0004] The aforementioned devices suffer from the drawbacks of traditional mining diaphragm pumps, which are mostly fixed installations or have bulky bases, lacking convenient moving structures. Their weight is concentrated and their center of gravity is relatively high. When moving them underground, they require the assistance of large equipment such as forklifts and cranes, or multiple people to lift them together. The operation is cumbersome and time-consuming, especially in narrow tunnels and temporary work sites, where the difficulty of moving them is extremely high, seriously affecting the timeliness of emergency drainage, temporary slurry transportation and other operations.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. 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.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example Reference Figure 1-4 This is an embodiment of the present utility model, which provides a portable pneumatic diaphragm pump for mining, comprising: The support assembly 100 includes a base 101, a support plate 102 fixedly connected to the end of the base 101, a bracket 103 fixedly connected to the side wall of the support plate 102, and a mounting seat 104 fixedly connected to the end of the bracket 103. The support plate 102 is symmetrically arranged on the side wall of the bracket 103, and the mounting seat 104 is symmetrically arranged at the end of the bracket 103. The power assembly 200 includes a pump body 201 fixedly installed at the end of the mounting base 104, an inlet 202 fixedly connected to the side wall of the pump body 201, an outlet 203 fixedly connected to the side wall of the pump body 201, a diaphragm 204 sealed inside the pump body 201, a connecting rod 205 fixedly connected to the middle position of the diaphragm 204, and an air distribution valve 206 disposed inside the pump body 201. The diaphragm 204 is symmetrically disposed at the end of the connecting rod 205, and a one-way valve is provided on the side wall of both the inlet 202 and the outlet 203.

[0020] Specifically, the operator first moves the entire device to the work point using the handle 105 hinged to the support plate 102, and fixes the base 101 by stepping on the brake structure of the caster 108; connects the external compressed air pipeline to the air port 208 on the side wall of the pump body 201, and connects the suction pipe and the discharge pipe to the inlet 202 and the outlet 203 respectively.

[0021] Furthermore, compressed air enters the pump body 201 through the air port 208 and first reaches the air distribution valve 206. The air distribution valve 206 is the "control center" of the pump. It uses the principle of airflow feedback to automatically perform periodic reversal. The two diaphragms 204 are rigidly connected by the connecting rod 205. The rightward movement of the left diaphragm will synchronously pull the right diaphragm to move towards the center. When the left diaphragm moves to its limit position, it will trigger the air distribution valve 206 to reverse, switching the airflow to the right air chamber, thereby pushing the right diaphragm to move to the left and pulling the left diaphragm back to its position. This cycle repeats, forming a stable reciprocating motion of the diaphragm 204 and connecting rod 205 assembly.

[0022] Preferably, the reciprocating motion of the diaphragm 204 directly changes the volume of the two hydraulic chambers formed by the pump body 201, the cover plate 207, and the diaphragm 204, thereby realizing liquid suction and discharge. When the left diaphragm is pulled towards the center, the volume of the left hydraulic chamber increases, creating a negative pressure inside. The pressure inside the chamber is lower than the external atmospheric pressure and the pressure in the inlet pipe. The one-way valve at the inlet 202 is opened under the action of the pressure difference, and the fluid is sucked into the left chamber. The one-way valve at the outlet 203 remains closed because the pressure inside the chamber is lower than the outlet pressure, preventing backflow of fluid. When compressed air drives the left diaphragm to move towards the cover plate 207, the volume of the left hydraulic chamber decreases, and the internal pressure increases sharply. This pressure closes the one-way valve at the inlet and simultaneously opens the one-way valve at the outlet 203, forcing the fluid in the chamber to be discharged through the outlet 203.

[0023] It should be noted that after the operation is completed, the gas source is cut off and the pipeline is disassembled; if the handle 105 is in the unfolded state, the handle bolt 107 on the side wall connector 106 of the support plate 102 can be loosened so that its end is not in the tight state with the side wall of the handle 105, and the handle 105 can be folded to save space; the entire pump can be easily transferred to the next work point by means of the handle 105 and the casters 108 at the bottom of the base 101.

[0024] Before operation, loosen the handle bolt 107 on the support plate 102, unfold the folded handle 105 to a suitable angle, and the operator holds the handle to push the equipment. After moving the equipment to the designated working position, step on the brake device on the caster 108 to lock the wheel body, and at the same time tighten the handle bolt 107 so that the rubber top block at the end of the bolt presses against the side wall of the handle 105 to fix the handle position and prevent shaking during operation. The symmetrically arranged support plate 102 and bracket 103 ensure that the equipment is placed stably and prevent the center of gravity from shifting and causing it to tip over. Connect the external compressed air pipeline to the air port 208 of the pump body 201 via a quick connector. The filter element inside the air port filters impurities in the compressed air. Connect the mining medium conveying pipeline to the inlet 202 and the outlet 203 via flanges to ensure a tight connection. When the compressed air supply system is started, compressed air enters the air distribution valve 206 inside the pump body 201 through the air port 208; the air distribution valve realizes the alternating entry and exit of compressed air between the two diaphragm chambers through the switching of the internal valve core; the cycle repeats to realize the continuous and directional delivery of the medium; During operation, the diaphragm 204 is sealed between the pump body 201 and the cover plate 207, and the sealing gasket on the side wall of the cover plate is tightly attached to the pump body and the cover plate to form a double sealing structure, which effectively prevents leakage of mining media. After the work is completed, turn off the compressed air supply and disconnect the air circuit and the medium delivery pipeline; loosen the brake device of the caster 108 and the handle bolt 107, fold and store the handle 105, and push the equipment to the next work position.

[0025] In summary, the support component 100 adopts a base 101 and evenly distributed casters 108. The casters can turn flexibly and have a certain load-bearing capacity. With the anti-slip handles 105 on the side wall of the support plate 102, a single person can push the pump body 201 to move in narrow underground tunnels and rugged surfaces without the need for large equipment. The handles can be quickly fixed at an angle by the handle bolts 107, making it easy to exert force when pushing and folding for storage when not in use, without taking up extra space. The time for a single relocation is shortened, making it suitable for scenarios such as emergency drainage and temporary work site relocation, and greatly improving the timeliness of operations.
