Description

Technical Field

[0001] This utility model relates to the field of self-priming pump technology, specifically a high-efficiency filter-type self-priming pump. Background Technology

[0002] Self-priming pumps are a type of self-priming centrifugal pump. They have advantages such as compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. No foot valve needs to be installed in the pipeline. Before operation, it is only necessary to ensure that the pump body contains a certain amount of priming liquid. Self-priming pumps are widely used in production and daily life, including factory and household water supply.

[0003] Existing self-priming pump filtration devices intercept impurities through built-in filters or separators, offering advantages such as compact structure and convenient installation. They effectively protect the pump body from particle abrasion, extending its service life, and some designs feature removable filter elements for easy cleaning and maintenance. However, the filter screens are easily clogged by fibrous impurities, leading to decreased self-priming performance and even cavitation. Therefore, we provide a high-efficiency filtering self-priming pump to solve these problems. Utility Model Content

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this high-efficiency filter-type self-priming pump has the following advantages:

[0017] I. This high-efficiency filter-type self-priming pump utilizes the impact or pressure of water flowing through the cylinder and impacting the blades on the rotating rod to drive the blades to rotate. This, in turn, causes the fixed rod to rotate synchronously, trapping fibrous impurities in the water around the outside of the fixed rod. When cleaning fibrous impurities, the filter mechanism is first disassembled. By pulling the blades to the right, the first and second adsorption plates are released from their adsorption connection. Simultaneously, the second adsorption plate slides to the left inside the groove, causing the rotating rod and fixed rod to move out of the cylinder. This facilitates the cleaning of fibrous impurities, achieving both high-efficiency filtration and cleaning. This solves the problem of filter screens being easily clogged by fibrous impurities, leading to decreased self-priming performance or even cavitation.

[0018] II. This high-efficiency filter-type self-priming pump allows for easy removal of the filter mechanism on one side by closing the first and second valves on one side, then releasing the first bolt and nut assembly from the first and third flanges on that side, and releasing the second bolt and nut assembly from the second and fourth flanges. Routine maintenance can then be performed on that side. After routine maintenance, the process can be reversed to quickly remove the filter mechanism on that side. This process requires no downtime, achieving convenient routine maintenance and solving the problem of frequent downtime for filter maintenance, which increases daily maintenance costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency filtering self-priming pump, including a self-priming pump body 1, a disassembly and assembly mechanism 2 on the right side of the self-priming pump body 1, and two mutually symmetrical filtering mechanisms 3 in the middle of the disassembly and assembly mechanism 2. The filtering mechanism 3 includes a cylinder 301 and a rotating rod 308. A third flange 302 is fixedly installed on the left side of the outer surface of the cylinder 301, and a fourth flange 303 is fixedly installed on the right side of the outer surface of the cylinder 301. Two mutually symmetrical sliding grooves 304 are opened on the inner side wall of the cylinder 301. A first adsorption plate 305 is fixedly connected to the left side of the inner side wall of each of the two sliding grooves 304. The right end of the rotating rod 308 is fixedly... A blade 310 is fixedly installed. Multiple sets of equidistant and concentric fixed rods 309 are fixedly connected to the outer surface of the rotating rod 308. A perforated plate 307 is fixedly connected to the left end of the rotating rod 308. Two mutually symmetrical second adsorption plates 306 are fixedly connected to the outer surface of the perforated plate 307. The left side of the third flange 302 is on the same vertical plane as the left side of the cylinder 301. The right side of the fourth flange 303 is on the same vertical plane as the right side of the cylinder 301. The outer surfaces of the two second adsorption plates 306 are slidably connected to the inner wall of the slide groove 304. The left side of the two second adsorption plates 306 are adsorbed and connected to the right side of the first adsorption plate 305.

[0027] The first adsorption plate 305 and the second adsorption plate 306 are both made of magnets. The sides of the first adsorption plate 305 and the second adsorption plate 306 that are close to each other attract each other. The cylinder 301 is made of high-strength plastic.

[0028] When water flows through the cylinder 301 and impacts the blades 310 on the rotating rod 308, the impact force or pressure of the water drives the blades 310 to rotate, which in turn drives the rotating rod 308 to rotate. This facilitates the synchronous rotation of the fixed rod 309, allowing fibrous impurities in the water to become entangled on the outside of the fixed rod 309. When cleaning fibrous impurities, the filter mechanism 3 is first removed. By pulling the blades 310 to the right, the adsorption connection between the first adsorption plate 305 and the second adsorption plate 306 is released. At the same time, the second adsorption plate 306 slides to the left inside the slide groove 304, thereby moving the rotating rod 308 and the fixed rod 309 out of the cylinder 301. This facilitates the cleaning of fibrous impurities, achieving the purpose of efficient filtration and cleaning of fibrous impurities. It solves the problem that the filter screen is easily clogged by fibrous impurities, leading to a decrease in self-priming performance or even cavitation.

[0029] The disassembly and assembly mechanism 2 includes a first tee pipe 201 and a second tee pipe 205. The left end of the main pipe of the first tee pipe 201 is connected to the inlet of the self-priming pump body 1. A first valve 202 is fixedly installed on the middle section of each of the two branch pipes of the first tee pipe 201. A first flange 203 is fixedly connected to the right side of the outer surface of each of the two branch pipes of the first tee pipe 201. The right side of the first flange 203 is on the same vertical plane as the right end face of the branch pipe of the first tee pipe 201. The first flange 203 is provided with multiple first bolt and nut sets 204. The first flange 203 is fixedly connected to the third flange 302 through the multiple first bolt and nut sets 204. The right end of the branch pipe of the first tee pipe 201 is connected to the left end of the cylinder 301. The middle section of the two branch pipes of the second tee pipe 205 is fixedly installed with a second valve 206. The left side of the outer surface of the two branch pipes of the second tee pipe 205 is fixedly connected with a second flange 207. The left side of the second flange 207 is on the same vertical plane as the left end face of the branch pipe of the second tee pipe 205. The second flange 207 is provided with multiple second bolt and nut groups 208. The second flange 207 is fixedly connected to the third flange 302 through multiple second bolt and nut groups 208. The left end of the branch pipe of the second tee pipe 205 is connected to the right end of the cylinder 301.

[0030] The first valve 202 and the second valve 206 are existing technologies and will not be described in detail here. A sealing ring is provided on the right side of the first flange 203 and on the left side of the second flange 207.

[0031] By closing the first valve 202 and the second valve 206 on one side of the front and rear sides, and then releasing the first bolt and nut group 204 from fixing the first flange 203 and the third flange 302 on this side, and releasing the second bolt and nut group 208 from fixing the second flange 207 and the fourth flange 303, the filter mechanism 3 on this side can be removed for routine maintenance. After routine maintenance is completed, the operation can be reversed to quickly remove the filter mechanism 3 on this side. This process does not require stopping the machine, thus achieving the purpose of convenient routine maintenance of this device and solving the problem of frequent machine shutdown for maintenance, which increases the cost of routine maintenance.

[0032] Working principle: In use, firstly, close the first valve 202 and the second valve 206 on one of the front and rear sides. Then, release the first bolt and nut group 204 from the first flange 203 and the third flange 302 on this side, and release the second bolt and nut group 208 from the second flange 207 and the fourth flange 303. Then, remove the filter mechanism 3 on this side for routine maintenance. After routine maintenance, the operation can be reversed to quickly remove the filter mechanism 3 on this side. This process does not require stopping the machine, achieving the purpose of convenient routine maintenance of this device. When water flows through the cylinder 301 and impacts the blades 310 on the rotating rod 308, the impact force of the water flow or Pressure drives the blade 310 to rotate, which in turn drives the rotating rod 308 to rotate, thus facilitating the synchronous rotation of the fixed rod 309. The rotation of the fixed rod 309 can entangle fibrous impurities in the water flow around the outside of the fixed rod 309. When cleaning fibrous impurities, the filter mechanism 3 is first removed. By pulling the blade 310 to the right, the adsorption connection between the first adsorption plate 305 and the second adsorption plate 306 is released. At the same time, the second adsorption plate 306 slides to the left inside the slide groove 304, thereby moving the rotating rod 308 and the fixed rod 309 out of the inside of the cylinder 301, which facilitates the cleaning of fibrous impurities and achieves the purpose of efficient filtration and cleaning of fibrous impurities.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
