Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a sand removal device for water treatment. Background Technology

[0002] Water treatment methods include physical and chemical treatment. Humans have been treating water for many years. Physical methods include using filter media with different pore sizes to remove impurities from the water through adsorption or blocking. Among adsorption methods, activated carbon is a more important one. Blocking methods involve passing water through filter media to prevent larger impurities from passing through, thus obtaining cleaner water. For wastewater with a high sand content, sand removal devices are needed to filter and remove the sand from the wastewater.

[0003] Currently, conventional sand removal devices for water treatment mostly use a single filter screen for filtration, resulting in poor filtration effect. Furthermore, the large amount of sediment remaining on the filter screen can easily cause blockage, making sand removal impossible. This requires manual cleaning of the filter screen at regular intervals, which is time-consuming, labor-intensive, and affects the use of the device. Therefore, we propose a sand removal device for water treatment to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sand removal device for water treatment, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A sand removal device for water treatment includes a rectangular box. Bearing assemblies are fixedly installed on the left and right side walls of the rectangular box near the upper side, and a filter screen sleeve is fixedly installed between the left and right bearing assemblies. A drive mechanism is fixedly installed on the right side of the rectangular box corresponding to the filter screen sleeve, and the drive mechanism is pulsatorically connected to the filter screen sleeve. A cylinder is fixedly installed on the left side of the rectangular box corresponding to the filter screen sleeve. A pushing mechanism is fixedly installed on the left side wall of the cylinder and is movably inserted into the filter screen sleeve. A water inlet pipe is fixedly installed on the upper surface of the cylinder. A filter mechanism is fixedly installed on the inner wall of the rectangular box near the lower side, and a water outlet pipe is fixedly installed at the lower edge of the left side wall of the rectangular box.

[0007] Furthermore, both the left and right sides of the filter screen cover are open structures, and the right end of the filter screen cover extends out of the outside of the right side wall of the rectangular box.

[0008] Furthermore, the driving mechanism includes an electric linear module, a rack, and a toothed ring. The electric linear module is fixedly installed on the right side of the rectangular box. A rack is fixedly installed on the lower surface of the slide of the electric linear module. A toothed ring is fixedly installed on the outer surface of the filter screen corresponding to the rack, and the toothed ring and the rack mesh with each other.

[0009] Furthermore, the feeding mechanism includes a rotating shaft, a mechanical seal, turbine blades, and a spiral feeding rod. The rotating shaft is installed on the left side wall of the cylinder through the mechanical seal. Turbine blades are fixedly installed on the rotating shaft at positions corresponding to the water inlet pipe. A spiral feeding rod is fixedly installed on the right side of the rotating shaft, and the spiral feeding rod is movably inserted into the filter screen sleeve.

[0010] Furthermore, the diameter of the spiral feed rod matches the inner diameter of the filter screen sleeve.

[0011] Furthermore, the filtration mechanism includes a filter screen and a discharge port. The filter screen is obliquely and fixedly installed between the inner walls of the rectangular box, and the right end of the filter screen extends out of the outer side of the right side wall of the rectangular box. The discharge port is provided on the right side wall of the rectangular box corresponding to the right end of the filter screen.

[0012] Compared with the prior art, this utility model provides a sand removal device for water treatment, which has the following beneficial effects:

[0013] This invention utilizes a filter screen to initially filter sediment in water, followed by a secondary filtration mechanism. This dual-function sand removal device enhances the sand removal effect. Furthermore, the pushing mechanism automatically discharges sediment from the filter screen, allowing it to flow automatically within the filtration mechanism without manual cleaning. The filter screen rotates periodically, preventing clogging and significantly improving sand removal efficiency, making it easy to use. Attached Figure Description

[0018] 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. Example

[0019] like Figures 1-3 As shown in the figure, an embodiment of the present invention discloses a sand removal device for water treatment, comprising a rectangular box 1. Bearing assemblies 2 are fixedly installed on the left and right side walls of the rectangular box 1 near the upper side, and a filter screen sleeve 3 is fixedly installed between the left and right bearing assemblies 2. A drive mechanism 4 is fixedly installed on the right side of the rectangular box 1 corresponding to the filter screen sleeve 3, and the drive mechanism 4 is pulsatorically connected to the filter screen sleeve 3. A cylinder 5 is fixedly installed on the left side of the rectangular box 1 corresponding to the filter screen sleeve 3. A pushing mechanism 6 is fixedly installed on the left side wall of the cylinder 5, and the pushing mechanism 6 is movably inserted into the filter screen sleeve 3. A water inlet pipe 7 is fixedly installed on the upper surface of the cylinder 5. A filter mechanism 8 is fixedly installed on the inner wall of the rectangular box 1 near the lower side, and a water outlet pipe 9 is fixedly installed at the lower edge of the left side wall of the rectangular box 1.

[0020] like Figure 2 As shown, in some embodiments, the left and right sides of the filter screen sleeve 3 are open structures, and the right end of the filter screen sleeve 3 extends out of the outside of the right side wall of the rectangular box 1.

[0021] In this embodiment, the left side opening of the filter screen sleeve 3 allows water and sediment to flow in, while the right side opening allows the filtered sediment to be discharged.

[0022] like Figure 2 As shown, in some embodiments, the drive mechanism 4 includes an electric linear module 401, a rack 402, and a toothed ring 403. The electric linear module 401 is fixedly installed on the right side of the rectangular box 1. The rack 402 is fixedly installed on the lower surface of the slide of the electric linear module 401. The toothed ring 403 is fixedly installed on the outer surface of the filter screen sleeve 3 corresponding to the rack 402, and the toothed ring 403 and the rack 402 mesh with each other.

[0023] In this embodiment, the slide of the electric linear module 401 drives the rack 402 to move back and forth in a stepping motion, causing the rack 402 to drive the gear ring 403 to rotate. The gear ring 403 drives the filter screen sleeve 3 to rotate in a stepping motion within the left and right bearing assemblies 2, so that different sides of the filter screen sleeve 3 face downwards. The mud and sand blocking the other sides fall off due to gravity and the vibration of the filter screen sleeve 3 caused by the screw feed rod 604, achieving the effect of cleaning the mud and sand on the filter screen sleeve 3, making the filter screen sleeve 3 less prone to clogging. The electric linear module 401 is connected to a timer switch, so that the electric linear module 401 is turned on at regular intervals.

[0024] like Figure 2 and Figure 3 As shown, in some embodiments, the feeding mechanism 6 includes a rotating shaft 601, a mechanical seal 602, a turbine blade 603, and a spiral feeding rod 604. The rotating shaft 601 is mounted on the left side wall of the cylinder 5 through the mechanical seal 602. The turbine blade 603 is fixedly mounted on the rotating shaft 601 at a position corresponding to the water inlet pipe 7. The spiral feeding rod 604 is fixedly mounted on the right side of the rotating shaft 601 and is movably inserted into the filter screen sleeve 3.

[0025] In this embodiment, the water flowing into the inlet pipe 7 drives the turbine blades 603 to rotate, which in turn drives the rotating shaft 601 to rotate within the mechanical seal 602. This causes the rotating shaft 601 to drive the screw feed rod 604 to rotate, which in turn rotates within the filter screen sleeve 3. The screw feed rod 604 then pushes the mud and sand in the filter screen sleeve 3 toward the right outlet of the filter screen sleeve 3, thus discharging the mud and sand.

[0026] like Figure 3 As shown, in some embodiments, the diameter of the spiral feed rod 604 matches the inner diameter of the filter screen sleeve 3.

[0027] In this embodiment, the spiral feed rod 604 can better discharge the mud and sand from the filter screen sleeve 3.

[0028] like Figure 2 As shown, in some embodiments, the filtering mechanism 8 includes a filter screen 801 and a discharge port 802. The filter screen 801 is obliquely fixed between the inner walls of the rectangular box 1, and the right end of the filter screen 801 extends out of the outer side of the right side wall of the rectangular box 1. The discharge port 802 is provided on the right side wall of the rectangular box 1 corresponding to the right end of the filter screen 801.

[0029] In this embodiment, the filter screen plate 801 performs secondary filtration of the mud and sand in the water. The filtered mud and sand move along the inclined filter screen plate 801 toward the discharge port 802, so that the mud and sand on the filter screen plate 801 can be discharged through the discharge port 802.

[0030] In use, water is pumped into the inlet pipe 7 by a booster pump. Water flows into the cylinder 5 through the inlet pipe 7, and then into the filter screen sleeve 3. The filter screen sleeve 3 filters the sediment in the water. The filtered water flows towards the filter plate 801 in the lower filter mechanism 8 within the rectangular box 1. The filter plate 801 filters the sediment again. The filtered water flows to the bottom of the rectangular box 1 and is discharged through the outlet pipe 9. The water flow from the inlet pipe 7 drives the turbine blades 603 in the pushing mechanism 6 to rotate. The turbine blades 603 drive the rotating shaft 601 to rotate within the mechanical seal 602, which in turn drives the spiral feed rod 604 to rotate. The spiral feed rod 604 rotates within the filter screen sleeve 3, pushing the sediment in the filter screen sleeve 3 towards the right outlet of the filter screen sleeve 3, thus discharging the sediment. Simultaneously, the filter screen... The silt filtered out on plate 801 moves along the inclined filter screen plate 801 toward the discharge port 802, allowing the silt on the filter screen plate 801 to be discharged through the discharge port 802. This gives the sand removal device a dual sand removal function, improving the sand removal effect and allowing the silt to be discharged automatically without manual cleaning. During use, the slide of the electric linear module 401 in the drive mechanism 4 drives the rack 402 to move back and forth, causing the rack 402 to drive the gear ring 403 to rotate. The gear ring 403 drives the filter screen sleeve 3 to rotate step by step in the left and right bearing assemblies 2, so that different sides of the filter screen sleeve 3 face downwards. The silt blocked on the other sides is dislodged by gravity and the vibration of the filter screen sleeve 3 driven by the spiral feed rod 604, achieving the effect of cleaning the silt on the filter screen sleeve 3. This makes the filter screen sleeve 3 less prone to clogging, eliminating the need to stop the machine for cleaning, greatly improving the sand removal efficiency and facilitating use.

[0031] In summary, this sand removal device for water treatment has a dual sand removal function through the filter screen sleeve 3 and the filter mechanism 8, which makes the sand removal effect better. It can also automatically discharge the filtered mud and sand without manual cleaning. The filter screen sleeve 3 is not easy to clog, which greatly improves the sand removal efficiency and is easy to use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
