[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to a movable sand pumping device. Background Art

[0002] In the actual operation process of domestic sewage treatment plants, the influent contains a large amount of inorganic sand and gravel. After passing through the pretreatment section such as coarse and fine grids and grit chambers, most of the inorganic sand and gravel can be isolated from the biochemical system. However, there is still some inorganic sand and gravel entering the lift pump station or biochemical system, and at this time, sand cleaning treatment is required.

[0003] When cleaning sand in the existing sewage tank, a sand pump is usually required. The sand pump is lowered to the bottom of the sewage tank by a lifting device, and the sand and gravel in the sewage tank are pumped out by suction. During long-term use and observation, it is found that during the sand cleaning process of the existing sewage tank, it is usually necessary to stop production and water supply. In the case of the sewage treatment plant stopping production and water supply, the sand cleaning process is relatively cumbersome, resulting in a long production stop time, and the sewage cannot enter the treatment station during this period, causing problems of accumulation and overflow.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Specific embodiments are given below.

[0025] As Figures 1 to 5As shown in the figure, a movable sand pumping device according to an embodiment of the present utility model includes a fixed frame 1; a first motor 11 is fixedly connected to the side wall of the fixed frame 1; a screw rod 12 is fixedly connected to the output end of the first motor 11; a slider 13 is connected to the middle of the screw rod 12 through a lead screw nut pair; a fixed frame 14 is fixedly connected to the bottom of the slider 13; a second motor 15 is fixedly connected to the side wall of the fixed frame 14; a wire roller 16 is fixedly connected to the output end of the second motor 15; a steel cable 110 is wound around the wire roller 16; a hook 17 is fixedly connected to the end of the steel cable 110; a sand pump 18 is provided at the bottom of the hook 17; a sand inlet pipe 19 is communicated with the side wall of the sand pump 18; during operation, when sand pumping work is carried out on the sewage tank, the fixed frame 1 is placed on the ground on both sides of the sewage tank, and then the hook 17 hooks the sand pump 18. The first motor 11 is started to drive the screw rod 12 to rotate, so that the slider 13 can slide in the middle of the screw rod 12. At this time, the slider 13 can drive the lower fixed frame 14, the second motor 15 and the wire roller 16 to move simultaneously. At this time, the sand pump 18 will move to a new position at the same time. When the sand pump 18 moves above the sand pumping position, the second motor 15 is started to drive the wire roller 16 to rotate, and the hook 17 is paid out to make the sand pump 18 enter the sewage tank for sand pumping. When the sand pumping work in this area is completed, the first motor 11 is started again to drive the slider 13 to move, so that the sand pump 18 moves to another sand pumping area for sand pumping. Through the above structure, the fixed frame 1 is set to connect the first motor 11 and the screw rod 12, and the second motor 15 and the wire roller 16 are used in cooperation. By installing the fixed frame 1 on the sewage tank, sand pumping can be carried out on the sewage tank without stopping production and water supply, reducing the situation that sewage cannot enter the treatment plant during production stoppage, resulting in sewage backflow. At the same time, it is convenient to adjust the position of the sand pump 18 to pump sand in different areas of the sewage tank, so as to improve the convenience during use.

[0026] As Figure 3 shown, a fixed shaft 2 is fixedly connected to the bottom of the inner side wall of the sand pump 18; a sleeve 21 is rotatably connected to the side wall of the fixed shaft 2; a plurality of blades 22 are fixedly connected to the side wall of the sleeve 21; a plurality of stirring rods 23 are fixedly connected to the side wall of the sleeve 21; during operation, when the sand and gravel in the sewage tank enter through the sand inlet pipe 19, they will pass over the blades 22. When the sand grains and water pass through the blades 22, they will drive the blades 22 and the sleeve 21 to rotate. At this time, the sleeve 21 can drive the stirring rods 23 to rotate, and the sand and gravel can be dispersed when they pass through. Through the above structure, the sleeve 21 is set to connect the blades 22 and the stirring rods 23, and the sand and gravel entering through the sand inlet pipe 19 can be dispersed, reducing the situation that the sand and gravel enter the sand pump 18 in a lump, resulting in blockage and damage.

[0027] As Figure 4As shown in the figure, a pair of clamping frames 3 are installed on the side of the fixing frame 1; a support plate 31 is fixedly connected to the side wall of the clamping frame 3; the pair of clamping frames 3 are connected by a first bolt 32; during operation, when the fixing frame 1 is placed in position, the clamping frame 3 is connected to the fixing frame 1, and then the position of the clamping frame 3 is adjusted so that the support plate 31 contacts the ground, and then the clamping frame 3 is connected by the first bolt 32 to lock the clamping frame 3 on the surface of the fixing frame 1. Through the above structure, the clamping frame 3 is provided with the support plate 31 and the first bolt 32 is used in cooperation, so that after the fixing frame 1 is placed in position, the position of the fixing frame 1 can be supported from both sides to improve the stability of the position of the fixing frame 1 when it is placed, improve the stability during the overall operation, and reduce the occurrence of tilting.

[0028] As Figure 3 shown, a filter screen 4 is provided at the end of the sand inlet pipe 19; the filter screen 4 is connected to the sand inlet pipe 19 by a second bolt 41; during operation, the filter screen 4 is connected to the sand inlet pipe 19 by the second bolt 41. When the sewage mixed with gravel enters from the sand inlet pipe 19, it will pass through the filter screen 4 and then enter the sand inlet pipe 19. At this time, the filter screen 4 will filter it and filter out impurities such as large pieces of garbage in the sewage tank. Through the above structure, the filter screen 4 is provided to be connected to the sand inlet pipe 19, so that the sewage can be filtered during sand pumping, and large pieces of garbage can be reduced from entering the sand inlet pipe 19, causing blockage and damage.

[0029] As Figure 5 shown, a fixing plate 5 is fixedly connected to the bottom of the fixing frame 14; a sliding hole 51 is opened in the middle of the fixing plate 5; a plurality of bristles 52 are fixedly connected in the sliding hole 51; during operation, when the wire roller 16 retracts and releases the hook 17, the hook 17 will pass through the fixing plate 5. When the hook 17 moves continuously, it will contact the bristles 52. At this time, the bristles 52 can clean the surface of the hook 17 and clean off some stains adhering to the surface of the hook 17. Through the above structure, the fixing plate 5 and the bristles 52 are provided, so that the hook 17 can be cleaned when it is retracted and released, and some stains adhering to the hook 17 when it enters the sewage tank can be cleaned off, so as to reduce the situation that stains adhere to the surface of the hook 17 and cause corrosion.

[0030] As Figure 5As shown, a plurality of damping springs 6 are fixedly connected to the bottom of the fixing plate 5; a buffer ring 61 is fixedly connected to the end of the damping spring 6; during operation, after sand pumping is completed, when the second motor 15 drives the fixing frame 1 to rotate and lift the sand pump 18, when the hook 17 approaches the bottom of the fixing plate 5, the top of the hook 17 will contact the buffer ring 61. At this time, the damping spring 6 will contract, causing the buffer ring 61 to move a certain distance towards the fixing plate 5, and then the damping spring 6 will rebound to reset the buffer ring 61, which can buffer when the hook 17 contacts the buffer ring 61. Through the above structure, by setting the damping spring 6 to connect the fixing plate 5 and the buffer ring 61, the impact force generated when the hook 17 moves towards the fixing plate 5 can be reduced, the stability of the hook 17 during winding can be improved, and the situation where the sand pump 18 shakes and falls off due to the impact force can be reduced.

[0031] As Figure 4 shown, a level 7 is fixedly connected to the side wall of the fixing frame 1; during operation, when the fixing frame 1 is placed on the ground, the state of the level 7 can be observed to determine whether the fixing frame 1 is in a horizontal state, so as to make corresponding adjustments. Through the above structure, setting the level 7 facilitates observing whether the position of the fixing frame 1 is horizontal, and reduces the situation where the sand pump 18 shakes greatly during unwinding due to inclination during operation.

[0032] Working principle: When sand pumping is carried out in the sewage tank, the fixed frame 1 is placed on the ground on both sides of the sewage tank, and then the hook 17 hooks the sand pump 18. Start the first motor 11 to drive the screw 12 to rotate, so that the slider 13 can slide in the middle of the screw 12. At this time, the slider 13 can drive the fixed frame 14 below, the second motor 15 and the wire roller 16 to move simultaneously. At this time, the sand pump 18 will move its position at the same time. When the sand pump 18 moves above the sand pumping position, start the second motor 15 to drive the wire roller 16 to rotate, release the wire of the hook 17 to make the sand pump 18 enter the sewage tank for sand pumping. When the sand pumping work in this area is completed, start the first motor 11 again to drive the slider 13 to move, so that the sand pump 18 moves to another sand pumping area for sand pumping. When the grit in the sewage tank enters through the sand inlet pipe 19, it will pass through the blades 22. When the sand grains and water pass through the blades 22, it will drive the blades 22 and the sleeve 21 to rotate. At this time, the sleeve 21 can drive the stirring rod 23 to rotate, and the grit can be broken up when it passes through. After the fixed frame 1 is placed in position, connect the clamping frame 3 to the fixed frame 1, then adjust the position of the clamping frame 3 so that the support plate 31 contacts the ground, and then connect the clamping frame 3 through the first bolt 32 to lock the clamping frame 3 on the surface of the fixed frame 1. Connect the filter screen 4 to the sand inlet pipe 19 through the second bolt 41. When the sewage mixed with grit enters through the sand inlet pipe 19, it will pass through the filter screen 4 and then enter the sand inlet pipe 19. At this time, the filter screen 4 will filter it to filter out large garbage and other impurities in the sewage tank. When the wire roller 16 winds and unwinds the hook 17, the hook 17 will pass through the fixed plate 5. When the hook 17 moves continuously, it will contact the brush hair 52. At this time, the brush hair 52 can clean the surface of the hook 17 and clean off some stains adhering to the surface of the hook 17. After the sand pumping is over, when the second motor 15 drives the fixed frame 1 to rotate and lift the sand pump 18, when the top of the hook 17 approaches the bottom of the fixed plate 5, the top of the hook 17 will contact the buffer ring 61. At this time, the damping spring 6 will contract, making the buffer ring 61 move a certain distance towards the fixed plate 5, and then the damping spring 6 will rebound to reset the buffer ring 61, which can buffer when the hook 17 contacts the buffer ring 61. When the fixed frame 1 is placed on the ground, the state of the spirit level 7 can be observed to judge whether the fixed frame 1 is in a horizontal state, so as to make corresponding adjustments.
