Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage pump device for sewage treatment. Background Art

[0002] Existing sewage pumps used for sewage treatment typically consist of core components such as the pump body, drive motor, impeller, inlet pipe, and outlet pipe. Their basic operating principle is that the drive motor rotates the impeller, creating negative pressure within the pump body. Sewage is drawn into the pump body through the inlet pipe and then pressurized by the impeller before being discharged through the outlet pipe.

[0003] The existing sewage pumps are not convenient for multi-directional cutting of particulate impurities in sewage, and it is difficult to comprehensively crush different forms of sewage, such as long strips, blocks and particulate impurities in different distribution directions. Large particulate impurities that are not completely crushed are easy to enter the pump body, which may wear the impeller or block the flow channel; moreover, floating or precipitated particulate impurities, such as fibers and silt blocks, are easy to accumulate on the outside of the water inlet of the water inlet pipe, which will lead to poor water inflow if not cleaned for a long time; filtering components, such as the filter holes of the filter screen, are easily clogged by fine particulate impurities, and lack an active cleaning structure, requiring frequent shutdowns for manual cleaning, which affects work efficiency. Therefore, it is necessary to develop a sewage pump device for sewage treatment. Summary of the Invention

[0039] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] See also Figures 1-9 , which shows a schematic diagram of the structure of a sewage pump device for sewage treatment according to the present invention, please refer to Figures 1-9 , a sewage pump device for sewage treatment is introduced in detail.

[0041] A sewage pump device for sewage treatment includes a sewage pump body 100, the horizontal cutting mechanism 200, the vertical cutting mechanism 300 and the anti-blocking mechanism 400;

[0042] The sewage pump body 100 includes a mounting pipe 101 and a pump housing 102 located below the mounting pipe 101. The mounting pipe 101 and the pump housing 102 are sealed and separated by a sealing plate 103. The center of the sealing plate 103 is rotated through a sealed bearing to provide a vertical main drive rod 104. The lower end of the main drive rod 104 is located in the pump housing 102 and is provided with an impeller 105. The water outlet on the side wall of the pump housing 102 is provided with a water outlet pipe 106. A vertical water inlet pipe 107 is provided at the water inlet at the bottom of the pump housing 102. A water inlet 108 is provided on the outer wall of the lower half of the water inlet pipe 107 around its own circumferential direction. A mounting plate 109 is fixedly provided in the middle of the inner cavity of the water inlet pipe 107. Three "leaf"-shaped filter plates 110 are evenly spaced and arranged around the mounting plate 109. Each filter plate 110 is evenly opened with filter holes 111. The inner diameter of the water inlet 108 is larger than the inner diameter of the filter holes 111.

[0043] The horizontal cutting mechanism 200 is arranged in the inner cavity of the water inlet pipe 107, below the mounting plate 109. When the sewage pump pumps water, the horizontal cutting mechanism 200 is driven simultaneously to cut the particulate impurities in the sewage entering the water inlet pipe 107 in the horizontal direction;

[0044] The vertical cutting mechanism 300 is disposed in the inner cavity of the water inlet pipe 107 and is located below the horizontal cutting mechanism 200. When the sewage pump pumps water, the vertical cutting mechanism 300 is simultaneously driven to vertically cut particulate impurities in the sewage entering the water inlet pipe 107.

[0045] The anti-blocking mechanism 400 is provided in the inner cavity of the water inlet pipe 107 and is located above the mounting plate 109. When the sewage pump is pumping water, the anti-blocking mechanism 400 is simultaneously driven to clean larger impurities blocking the outside of the water inlet 108.

[0046] In this embodiment, the horizontal cutting mechanism 200 and the vertical cutting mechanism 300 can cut particulate impurities from different directions, and the anti-blocking mechanism 400 can clear particulate impurities outside the water inlet 108, which helps reduce the risk of particulate impurities blocking and improves the continuous operation of the sewage pump. The filter plate 110 can filter particulate impurities, while particulate impurities that cannot be filtered will continue to be cut by the horizontal cutting mechanism 200 and the vertical cutting mechanism 300.

[0047] Furthermore, a vertical servo motor 113 is fixedly mounted on the top of the sewage pump body 100 via a motor mounting base 112. The output shaft of the servo motor 113 rotates through the top of the mounting tube 101 via a bearing and is fixedly connected to the upper end of the main drive rod 104 via a coupling. The servo motor 113 is connected to the main drive rod 104 via a coupling, which can provide stable power to the sewage pump body 100 and various cutting and anti-blocking mechanisms, helping to ensure the synchronization and reliability of the operation of various components.

[0048] Furthermore, a cleaning brush plate 114 is fixedly provided on the rod body of the main driving rod 104. The cleaning brush plate 114 is located above the mounting plate 109, and the rotating cleaning brush plate 114 is used to clean the surface of the filter hole 111. The cleaning brush plate 114 rotates with the main driving rod 104 to clean the surface of the filter hole 111 of the filter plate 110, thereby helping to reduce the clogging of the filter hole 111 by particulate impurities and maintain the filtering effect.

[0049] Furthermore, an upper bracket 115 and a lower bracket 116 are fixedly provided on the inner side wall of the water inlet pipe 107 above and below the mounting plate 109, respectively. The cross-section of the upper bracket 115 and the lower bracket 116 is in the shape of a "triangle" star when viewed from above. The rod body of the main driving rod 104 rotates vertically through the centers of the upper and lower walls of the upper bracket 115 and the lower bracket 116 through a sealed bearing; the upper bracket 115 and the lower bracket 116 are in the shape of a "triangle", which can not only stably support the main driving rod 104, but also reduce obstruction to the water flow, thereby helping to ensure that the water flows smoothly through the water inlet pipe 107 and at the same time enhance the stability of the overall structure.

[0050] Example 2, based on Example 1, the horizontal cutting mechanism 200 includes a mounting cavity 201 opened in the inner cavity of the mounting plate 109, the three filter plates 110 are arranged around the outside of the mounting cavity 201, and are staggered with the mounting cavity 201. The inner cavity bottom wall of the mounting cavity 201 is rotatably provided with a plurality of vertical first rotating rods 202 through sealed bearings, and the lower ends of all the first rotating rods 202 are rotatably provided on the top of the lower bracket 116 through sealed bearings. The rod body of the first rotating rod 202 is located in the inner cavity of the mounting cavity 201 and is fixedly installed with a follower gear 203. All the follower gears 203 are connected to the main drive rod 104. The main drive rod 104 is arranged in a circumferential manner with equal spacing along the axis. The main drive rod 104 is located in the mounting cavity 201 and is fixedly provided with a driving gear 204 that is always engaged with all the follower gears 203. The main drive rod 104 is located below the mounting plate 109 and is fixedly provided with a first cutting blade 205 circumferentially with equal spacing along the axis of the first rotating rod 202. The horizontal cutting mechanism 200 drives the follower gear 203 and the first rotating rod 202 to rotate through the driving gear 204, so that the first cutting blade 205 cuts the particulate impurities in the horizontal direction, which helps to crush the horizontal particulate impurities and cooperates with the filter plate 110 to improve the particulate impurity treatment effect.

[0051] Furthermore, an annular cutting blade 206 is provided in the middle and lower part of the inner wall of the water inlet pipe 107. The vertical cross-section of the annular cutting blade 206 is an "isosceles triangle". The annular cutting blade 206 is used to cut the granular impurities in the sewage in an alternating manner with the first cutting blade 205. The annular cutting blade 206 and the first cutting blade 205 cut in an alternating manner, which can enhance the cutting effect of the granular impurities in the sewage, help to more fully crush the granular impurities, and reduce the possibility of blockage.

[0052] Example 3, on the basis of Example 1, the vertical cutting mechanism 300 includes a central mounting cylinder 301 fixed to the bottom of the lower bracket 116, the mounting cylinder 301 is a hollow inverted "T" cylindrical shape, and the rod body and the lower end of the main driving rod 104 are rotatably arranged in the inner cavity of the mounting cylinder 301 through a sealed bearing, and the side wall of the mounting cylinder 301 is equidistantly arranged with horizontal second rotating rods 302 around the vertical axis of the main driving rod 104, one end of each second rotating rod 302 is rotated through the inner wall of the mounting cylinder 301 through a sealed bearing, and the other end is rotated through the inner wall of the mounting cylinder 301 through a sealed bearing. The second rotating rod 302 is circumferentially fixed with a second cutting blade 303 at equal intervals around the axis of the second rotating rod 302 in the longitudinal direction. The second cutting blade 303 is located between the outer side of the mounting cylinder 301 and the inner side of the water inlet pipe 107 and below the first cutting blade 205 and the lower bracket 116. The second rotating rod 302 of the vertical cutting mechanism 300 drives the second cutting blade 303 to cut in the vertical direction, and cooperates with the horizontal cutting mechanism 200 to form a three-dimensional cutting, which helps to improve the comprehensiveness of the crushing of granular impurities of different shapes.

[0053] Furthermore, a horizontal first bevel gear 304 is fixedly provided at the bottom of the rod body of the main driving rod 104, and each of the second rotating rods 302 is fixedly provided with a second bevel gear 305 that engages with the first bevel gear 304 at one end located in the inner cavity of the mounting cylinder 301. The first bevel gear 304 is engaged with the second bevel gear 305, which can convert the vertical rotation of the main driving rod 104 into the horizontal rotation of the second rotating rod 302, thereby ensuring the power transmission of the vertical cutting mechanism 300 and helping to improve the transmission efficiency and stability.

[0054] Example 4. On the basis of Example 1, the anti-blocking mechanism 400 includes a hollow cylindrical fixed cylinder 401 fixed to the center of the upper bracket 115, and the rod body of the main driving rod 104 is rotated through a sealed bearing and is located in the inner cavity of the fixed cylinder 401.

One end of each of the third rotating rods 402 rotates through the inner wall of the fixed cylinder 401 through a sealed bearing, and the other end rotates through the outer wall of the water inlet pipe 107 through a sealed bearing. The end of the third rotating rod 402 located on the outside of the water inlet pipe 107 is fixed with a linkage rod 403 perpendicular to the third rotating rod 402, and the other end of the linkage rod 403 is rotatably provided with a push-pull rod 404 through a rotating shaft.

[0056] The specific use process of the sewage pump device for sewage treatment is as follows:

[0057] Starting power source: The device is started by the servo motor 113. The output shaft of the servo motor 113 drives the main driving rod 104 to rotate through the coupling. The impeller 105 at the lower end of the main driving rod 104 rotates synchronously with it, forming a negative pressure in the pump housing 102 and the water inlet pipe 107. The sewage is sucked into the inner cavity of the water inlet pipe 107 from the water inlet 108 in the lower half of the water inlet pipe 107.

[0058] Cutting granular impurities in the vertical direction: When the main driving rod 104 rotates, the first bevel gear 304 at the bottom of the rod body rotates synchronously, and through engagement with the second bevel gear 305, drives the second rotating rod 302 of the vertical cutting mechanism 300 to rotate horizontally, so that the second cutting blade 303 cuts the larger granular impurities in the sewage entering the water inlet pipe 107 in the vertical direction, and preliminarily crushes the granular impurities.

[0059] Horizontal cutting of granular impurities: When the main driving rod 104 rotates, the driving gear 204 located in the installation cavity 201 drives the follower gear 203 and the first rotating rod 202 to rotate vertically, so that the first cutting blade 205 of the horizontal cutting mechanism 200 rotates, and interlocks with the annular cutting blade 206 on the inner wall of the water inlet pipe 107, so as to further cut the granular impurities that have been vertically cut in the horizontal direction, thereby improving the crushing effect of the granular impurities.

[0060] Filtration and cleaning of the filter holes: The sewage after two-stage cutting flows upward and passes through the filter plate 110 and the filter holes 111 on the mounting plate 109 to filter out fine particles of impurities in the sewage; at the same time, the cleaning brush plate 114 on the main driving rod 104 rotates with it to clean the surface of the filter holes 111 of the filter plate 110, thereby reducing blockage caused by the adhesion of particulate impurities.

[0061] Cleaning larger impurities on the outside of the water inlet: When the main driving rod 104 rotates, the first bevel gear 408 located in the fixed cylinder 401 drives the second bevel gear 409 to rotate, causing the third rotating rod 402 of the anti-blocking mechanism 400 to rotate horizontally, and through the transmission of the linkage rod 403 and the push-pull rod 404, the push-pull scraper 407 is driven to slide up and down along the limiting slide rod 406 to clean larger impurities blocked on the outside of the water inlet 108, ensuring smooth water inlet.

[0062] Sewage discharge: The filtered sewage enters the pump housing 102 and is transported to the outlet pipe 106 on the side wall of the pump housing 102 under the continuous rotation of the impeller 105, and finally discharged from the device, completing the sewage treatment and transportation process.

[0063] During the entire process, the upper bracket 115 and the lower bracket 116 provide stable support for the main drive rod 104 and the rotating rods, and the sealing plate 103 and the sealed bearings ensure the sealing of the device to prevent sewage leakage.

In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation.
