Description

Technical Field

[0001] The invention belongs to the technical field of slurry pumps, in particular to a wear-resistant slurry pump body. Background Art

[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixed medium by means of centrifugal force (the rotation of the pump's impeller). It is a device that converts electrical energy into kinetic energy and potential energy of the medium. It is mainly suitable for industries such as mining, power plants, dredging, metallurgy, chemicals, building materials and petroleum. Ceramic sheets are installed on the inner walls of the front and rear pump casings in the pump body to improve the wear resistance of the pump body.

[0003] The Chinese patent application No. 201710239398.8 discloses a wear-resistant slurry pump body. In order to improve the wear resistance of the pump body during use, the patent uses wear-resistant ceramic sheets to be attached to the inner wall of the pump body by adhesive. However, the ceramic sheets are attached to the inner wall of the pump body by adhesive. During long-term use, the ceramic sheets are prone to fall off, causing the wear resistance of the pump body to be greatly reduced. Moreover, when removing the worn ceramic sheets in the later stage, it is necessary to use an electric pick to knock and remove the ceramic sheets attached to the inner wall of the pump body. This not only increases the workload, but also easily damages the inner wall of the pump body, affecting the use of the slurry pump in the later stage. For this reason, we propose a wear-resistant slurry pump body. Summary of the invention

[0052] Example 2

[0053] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 The rotating assembly includes a mounting bearing 304 and an outer gear ring 303 sleeved and fixed on the outer wall of the mounting bearing 304. The inner walls of the front pump housing 101 and the rear pump housing 103 are fixedly provided with a plurality of sets of fixing columns 315. The mounting bearing 304 is fixed to the pump body through the fixing columns 315, and the inner wall of the mounting bearing 304 is fixed to the fixing columns 315.

[0054] The inner walls of the front pump housing 101 and the rear pump housing 103 are rotatably provided with connecting rods 311 and multiple sets of rotating shafts 312 respectively, and the outsides of the connecting rods 311 and the rotating shafts 312 are fixedly provided with gears 314, and a vertical tooth plate 313 is fixedly provided on one side of the T-shaped slide plate 305. The gear 314 is meshingly connected with the vertical tooth plate 313 and the outer gear ring 303, and a T-shaped rotary handle 205 is fixedly provided on the end of the connecting rod 311. The arc-shaped clamping plate 300, the middle plate 309 and the T-shaped slide plate 305 can be moved by rotating the T-shaped rotary handle 205. A sealed bearing 203 is fixedly provided on the outer sleeve of the T-shaped rotary handle 205.

[0055] The present invention is designed with a disassembly and assembly mechanism, which can facilitate the disassembly, assembly and replacement of the ceramic sheet 104 during use. The locking screw 310 on the middle plate 309 is turned outward to unscrew it, and the arc-shaped clamping plate 300 is rotated in a direction away from the ceramic sheet 104 so that it no longer contacts the inner wall of the ceramic sheet 104. Then, the T-shaped slide plate 305 is slid toward the mounting seat 302 so that the middle plate 309 no longer contacts the ceramic sheet 104. At this time, the ceramic sheet 104 is moved outward to be removed, which is convenient for removing it from the pump body. Disassembly can be performed without using tools such as electric picks, thereby reducing the workload of personnel and not easily causing damage to the inner walls of the front pump casing 101 and the rear pump casing 103 in the pump body, thereby extending the service life of the slurry pump.

[0056] During use, water is sucked into the pump from the inlet 102 under the action of the centrifugal force generated by the rotation of the impeller in the pump body. At the same time, the volume inside the pump body increases to form a low-pressure area. The liquid generates a pressure difference, thereby driving the liquid to flow and be discharged from the outlet 100. When the ceramic sheet 104 needs to be replaced during use, the ceramic sheet 104 is disassembled and replaced. During replacement, the pump body is opened, and then the locking screw 310 located on the arc-shaped clamping plate 300 is rotated in the direction away from the arc-shaped clamping plate 300. Then the working end of the locking screw 310 is disengaged from the first screw hole in the middle plate 309. Then the arc-shaped clamping plate 300 is rotated outward to a certain angle and then stopped. At this time, the outer wall of the arc-shaped clamping plate 300 is no longer in contact with the inner wall of the ceramic sheet 104. Then the T-shaped rotary handle 205 is rotated to drive the gear 314 located outside the connecting rod 311 to rotate through the connecting rod 311, and then The gear 314 drives the outer gear ring 303 to rotate, and then drives the vertical tooth plate 313 to move toward the mounting seat 302. At this time, the outer gear ring 303 will drive the gear 314 located on the rotating shaft 312 to rotate, and then drive the other vertical tooth plates 313 and the T-shaped slide 305 to move, and then drive the T-shaped slide 305 to slide in the track 301, and then the middle plate 309 moves with the movement of the T-shaped slide 305 and no longer contacts the inner wall of the ceramic sheet 104. At this time, the ceramic sheet 104 is moved outward for removal. At this time, the first arc-shaped embedded groove 307 in the ceramic sheet 104 no longer contacts the second arc-shaped limiting strip 308, and the second arc-shaped embedded groove in the ceramic sheet 104 no longer contacts the first arc-shaped limiting strip 306, so it can be disassembled, and then the new ceramic sheet 104 is taken out and installed according to the above-mentioned reverse principle, so as to facilitate the disassembly, assembly and replacement of the ceramic sheet 104.

[0057] Example 3

[0058] Based on Example 2, please refer to Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.13 The surface of the T-shaped slide plate 305 is provided with rolling elements that can reduce wear on the contact between the T-shaped slide plate 305 and the inner walls of the front pump housing 101 and the rear pump housing 103. The rolling elements include a vertical plate 400 installed on the surface of the T-shaped slide plate 305. The surface of the vertical plate 400 is provided with a plurality of groups of rolling balls 401. The rolling balls 401 can roll when they contact the inner walls of the front pump housing 101 and the rear pump housing 103. The outer wall of the vertical plate 400 contacts the inner walls of the front pump housing 101 and the rear pump housing 103.

[0059] A mounting plate 402 is fixedly provided on the side of the vertical plate 400, and a side plate 403 is fixedly provided on the other side of the T-shaped slide plate 305. The side plate 403 and the mounting plate 402 are fixedly connected by two sets of screws, and the vertical plate 400 can be disassembled, assembled and replaced by screws.

[0060] The present invention adopts a designed rolling element, which allows the T-shaped slide plate 305 to slide on the track 301 during the process of disassembling and assembling the ceramic sheet 104, and the ball 401 on the vertical plate 400 rolls on the inner walls of the front pump housing 101 and the rear pump housing 103, thereby reducing the probability of friction and wear caused by the T-shaped slide plate 305 directly contacting and sliding with the inner walls of the front pump housing 101 and the rear pump housing 103.

[0061] During use, when the T-shaped slide plate 305 slides in the track 301, the vertical plate 400 is driven to move along with it. At this time, the ball 401 located on the vertical plate 400 contacts the inner walls of the front pump housing 101 and the rear pump housing 103 and rolls, which can reduce the probability of friction and wear caused by the T-shaped slide plate 305 directly contacting and sliding with the inner walls of the front pump housing 101 and the rear pump housing 103. When the vertical plate 400, the ball 401, etc. need to be replaced after a long period of use, the screws on the mounting plate 402 and the side plate 403 can be unscrewed and the plate can be removed for replacement.

[0062] Example 4

[0063] Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.14 The outer walls of the rear pump housing 103 and the front pump housing 101 are both provided with clamping members for clamping and limiting the outer gear ring 303. The clamping members include a fixing plate 200 installed on the surface of the rear pump housing 103 and the front pump housing 101. A hydraulic rod 204 is fixedly provided at the bottom of the fixing plate 200. The hydraulic rod 204 can make the arc-shaped clamping plate 202 move up and down, so as to clamp the fixing collar 201 located outside the T-shaped rotary handle 205. The working end of the hydraulic rod 204 is fixedly provided with the arc-shaped clamping plate 202. The outer sleeve of the T-shaped rotary handle 205 is fixed with the fixing collar 201. The inner wall of the arc-shaped clamping plate 202 contacts the outer wall of the fixing collar 201.

[0064] Two sets of limiting rods 206 are slidingly arranged inside the fixed plate 200. When the arc-shaped clamping plate 202 moves up and down, the limiting rods 206 are driven to slide in the fixed plate 200 to increase stability during the up and down movement, and the bottom of the limiting rods 206 extends to the outer wall of the arc-shaped clamping plate 202.

[0065] The clamping piece designed in the present invention can clamp and limit the outer gear ring 303 during use, so as to prevent the vibration generated by the water pump during use from causing the outer gear ring 303 to rotate, affecting the movement of the arc-shaped clamping plate 300 and affecting the tightness of the ceramic sheet 104, thereby affecting the fixing firmness of the ceramic sheet 104.

[0066] When replacing the ceramic sheet 104, the outer gear ring 303 is clamped and limited. When limiting, the hydraulic rod 204 located on the fixed plate 200 is started, and then the working end of the hydraulic rod 204 is extended downward, driving the arc clamping plate 202 to move downward, and then the inner wall of the arc clamping plate 202 contacts and clamps the fixing ring 201, so that the T-shaped rotary handle 205 and the outer gear ring 303 can be limited, so as to prevent the vibration generated by the water pump during use from causing the outer gear ring 303 to rotate, affecting the movement of the arc clamping plate 300, thereby affecting the firmness of the ceramic sheet 104.

[0067] Example 5

[0068] Based on Example 4, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.15 The inner walls of the front pump housing 101 and the rear pump housing 103 are both provided with scraping members for cleaning the dirt on the inner walls of the front pump housing 101 and the rear pump housing 103. The scraping members include a first scraper 500, two sets of second scrapers 502 installed on the surface of the vertical plate 400, and a recessed frame 501 slidably arranged on the outer ring gear 303 and the outer side of the mounting bearing 304. The surface of the outer ring gear 303 is provided with a plurality of groups of insertion holes 507. A second T-shaped column 505 is slidably arranged inside the recessed frame 501. The working end of the second T-shaped column 505 penetrates into the interior of the insertion hole 507. The outer sleeve of the second T-shaped column 505 is provided with an installation spring 504. By installing the spring 504, the The second T-shaped column 505 is always in a state of being inserted into the insertion hole 507, and the two ends of the mounting spring 504 are respectively fixed on the recess 501 and the second T-shaped column 505, the end of the second T-shaped column 505 can be inserted into the corresponding insertion hole 507 in the outer gear ring 303, two groups of extension plates 506 are fixedly arranged on the recess 501, the first T-shaped column 503 is slidably arranged inside the extension plate 506, the end of the first T-shaped column 503 is fixed on the first scraper 500, the outside of the first T-shaped column 503 is sleeved with a fixing spring 508, and the two ends of the fixing spring 508 are respectively fixed on the first scraper 500 and the first T-shaped column 503.

[0069] The scraper designed in the present invention will drive the recessed frame 501 and the first scraper 500 to rotate when the outer gear ring 303 rotates during use, and will drive the second scraper 502 to move when the vertical plate 400 moves. The first scraper 500 and the second scraper 502 can be used to scrape and clean the dirt attached to the inner walls of the front pump casing 101 and the rear pump casing 103, thereby cleaning the dirt on the inner wall surface of the pump body and improving the use effect of the pump body.

[0070] During use, when the outer gear ring 303 rotates, it will drive the second T-shaped column 505 inserted into the insertion hole 507 to rotate, and then drive the recessed frame 501 and the first scraper 500 to rotate, so as to scrape the dirt on the inner wall of the pump body. During this process, the fixed spring 508 can continuously make the first scraper 500 produce an extrusion force in the direction close to the inner wall of the pump body, thereby increasing the fit between the first scraper 500 and the inner walls of the front pump shell 101 and the rear pump shell 103 in the pump body, and increasing the effect of the first scraper 500 in scraping off dirt. As the outer gear ring 303 rotates, it contacts the mounting seat 302 and the track 301 and stops moving. At this time, the outer gear ring 303 continues to rotate. The end of the second T-shaped column 505 is a spherical structure. When the outer gear ring 303 rotates, the spherical structure of the end of the second T-shaped column 505 inserted into the insertion hole 507 touches the outer edge of the insertion hole 507 and moves outward. During this period, due to the continued rotation of the outer gear ring 303, the spherical structure of the end of the second T-shaped column 505 will be separated from the inside of the insertion hole 507 and contact the surface of the outer gear ring 303. When the mounting spring 504 is stretched, the end of the second T-shaped column 505 is disengaged from the inside of the socket 507 under the rotation of the outer gear ring 303, and then inserted into another set of corresponding sockets 507 next to it, which can not only realize the end of the second T-shaped column 505 is inserted into the socket 507, but also enable the first scraper 500 to contact the mounting seat 302 and the rail 301. The end of the second T-shaped column 505 can be disengaged from the socket 507 and inserted into another set of corresponding sockets 507, and this is repeated until the outer gear ring 303 stops rotating. When 03 rotates in the opposite direction, the first scraper 500 is driven to move along. When the first scraper 500 moves to contact the mounting seat 302 and the track 301 on the other side, the second T-shaped column 505 inserted into the insertion hole 507 moves outward again. At this time, the mounting spring 504 is stretched. Under the rotation of the outer gear ring 303, the end of the second T-shaped column 505 is separated from the inside of the insertion hole 507, and then inserted into the corresponding insertion hole 507 next to it, so that the first scraper 500 stops moving after contacting the mounting seat 302 and the track 301.

[0071] When the vertical plate 400 drives the second scraper 502 to move, the dirt on the inner walls of the front pump housing 101 and the rear pump housing 103 can be scraped off. The dirt on the inner walls of the front pump housing 101 and the rear pump housing 103 can be cleaned by the first scraper 500 and the second scraper 502.

[0072] In this embodiment, the rear pump casing 103 and the front pump casing 101 are fixedly connected by multiple sets of bolts, and the front pump casing 101 and the rear pump casing 103 in the pump body can be opened by the bolts. The front pump casing 101 is provided with an inlet 102 on the front side, and the rear pump casing 103 is provided with a driving port on the back side. The driving shaft that drives the impeller in the pump body to rotate can enter the pump body through the driving port and be connected with the impeller. The tops of the front pump casing 101 and the rear pump casing 103 are both provided with outlets 100.
