Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purification technology, specifically a solid-liquid separation device for water purification. Background Technology
[0002] Due to economic development, population growth, and increasing wastewater discharge, water pollution has become increasingly serious. Water treatment work and technologies are of great importance. Currently, the main methods of water treatment are divided into two categories: physical treatment and chemical treatment. For some water quality with mild secondary suspended solids pollution or domestic sewage, further in-depth treatment mostly uses physical and chemical treatment as a means of water purification.
[0003] A wastewater stratified purification device is disclosed in CN219885838U, belonging to the field of wastewater purification technology. It includes a solid-liquid separation tank, a water-oil separation tank, a disinfection and purification tank, and a deep filtration tank. The upper side of the solid-liquid separation tank is connected to a water inlet pipe. Several sliding grooves are respectively opened on both sides of the interior of the solid-liquid separation tank. Several filter plates are installed inside the solid-liquid separation tank. The beneficial effect of this invention is that a water quality detector is installed at the lower end of the deep filtration tank. The water quality detector detects the water quality and transmits the detected water quality value to a controller. The controller displays the corresponding value on a display screen. The controller determines whether the water quality filtration is qualified based on the value. If qualified, the electric valve opens and the filtered water is released through the outlet pipe. If unqualified, a fourth water pump is activated to draw water into the solid-liquid separation tank for re-filtration, resulting in a better filtration effect.
[0004] In the process of water purification, a key step is to achieve effective solid-liquid separation of substances in the water. This step is crucial to ensuring that the water quality meets purification standards. The aforementioned wastewater stratification purification equipment design adopts a multi-box structure, with each box undertaking different functions. Although the main separation process is completed through filter plates, this equipment has relatively few filtration stages, which may lead to incomplete water purification during water transportation. In addition, existing solid-liquid separation devices are usually bulky, which not only affects their space utilization efficiency but may also occupy too much space in practical applications. In order to improve filtration efficiency, the filtration function is managed by partition, but this approach further increases the overall size of the solid-liquid separation device. Furthermore, in practical applications, the filtration function mainly relies on filter consumables to complete the process. However, this method is relatively simple and lacks effective integration of filter consumables with physical structural means. This single reliance limits the full utilization of the filtration function, fails to fully utilize the potential of filter consumables, and also fails to leverage the advantages of physical structure to improve filtration efficiency and effect.
[0005] Therefore, those skilled in the art have provided a solid-liquid separation device for water purification to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to provide a solid-liquid separation device for water purification, in order to solve the problems mentioned in the background art of poor structural integration and limited filtration function of existing solid-liquid separation devices for water purification.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A solid-liquid separation device for water purification includes: a mounting bracket, an mounting cylinder fixedly mounted on the front side of the mounting bracket, a connecting pipe connected to one side of the mounting cylinder, a centrifugal pump mounted at the lower end of the connecting pipe, a filter tank mounted at the output end of the centrifugal pump, a filter box mounted inside the filter tank, an inclined flow surface integrally formed inside the filter box, a flow guide filter plate fixedly mounted on the surface of the inclined flow surface, a water filter perforated plate provided at the lower end of the inclined flow surface, a booster pump mounted at the bottom of the filter tank, a water outlet pipe connected to the output end of the booster pump, a multi-stage filter barrel connected to the output end of the water outlet pipe, a series booster pump pipe for connecting the multi-stage filter barrels in series, and a purified water pipe connected to the drain end of the multi-stage filter barrel.
[0009] As a further improvement of this utility model: several filter boxes are arranged vertically and parallel inside the filter tank, and the upper and lower layers of the filter boxes are arranged in a mirror image.
[0010] As a further improvement of this utility model: the flow guide filter plate is provided in three sets on the inclined flow surface, and the inclination angle of the flow guide filter plate on the inclined flow surface is 15 degrees.
[0011] As a further embodiment of this utility model: the top of the mounting cylinder is connected to a water inlet pipe, and a sealing thread cap is installed on the internal thread of the mounting cylinder. A fine-pore filter element is fitted on the top of the sealing thread cap, and a wrench is fixedly connected to the bottom of the sealing thread cap.
[0012] As a further embodiment of this utility model: the sealing threaded cap and the mounting cylinder are connected by a threaded structure, and the mounting cylinder is connected to the centrifugal pump through a connecting pipe.
[0013] As a further improvement of this utility model: the booster pump and the outlet pipe are connected by a flange, a valve is installed on the surface of the outlet pipe, and a flow meter is installed at the connection between the output end of the outlet pipe and the series booster pump pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] Using a mounting bracket, the mounting cylinder, filter pipe, and multi-stage filter tank are integrated and mounted on the bracket. Multiple sets of pipes and valves work together to further reduce the overall installation volume of the solid-liquid separation device and improve its convenience. The multi-stage filter tank is installed on the back of the filter tank via an outlet pipe, further improving space utilization. The interior of the mounting cylinder is sealed with a threaded connection structure using a threaded cap, which, along with a fine-pore filter element inside the mounting cylinder, filters the incoming water. The filtered water enters the filter tank via a centrifugal pump. A filter box is installed inside the filter tank, with an inclined surface design that allows water to flow along the inclined surface. During the flow, the water will come into contact with the guide filter plate. Due to the influence of the water flow velocity, some water will permeate through the guide filter plate to the lower guide filter plate, while some will flow down the inclined guide filter plate to the lower guide filter plate. Multiple sets of guide filter plates are set on the inclined surface, and multi-stage interception filtration is carried out by using the inclined surface. The upper and lower filter boxes are set in a mirror image, and the water can be repeatedly filtered by deflection during the filtration process. Through the combination of physical structure and filter consumables, the filtration effect is greatly improved, and the water quality is further improved. When the purified water is discharged at the end, the water is allowed to pass through the multi-stage filter barrel again for further filtration, so that the final water quality is even higher.

[0021] 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.
[0022] Please see Figures 1-4 This utility model provides a solid-liquid separation device for water purification, including: a mounting bracket 1, an mounting cylinder 2 fixedly mounted on the front side of the mounting bracket 1, a connecting pipe 10 connected to one side of the mounting cylinder 2, a centrifugal pump 4 mounted at the lower end of the connecting pipe 10, a filter tank 5 mounted at the output end of the centrifugal pump 4, a water inlet pipe 3 connected to the top of the mounting cylinder 2, a sealing threaded cap 201 mounted on the internal thread of the mounting cylinder 2, a fine-pore filter element 203 fitted above the sealing threaded cap 201, a wrench 202 fixedly connected to the bottom of the sealing threaded cap 201, and a threaded connection between the sealing threaded cap 201 and the mounting cylinder 2. The mounting cylinder 2 is connected to the centrifugal pump 4 through the connecting pipe 10.
[0023] Specifically, water enters the mounting cylinder 2 through the inlet pipe 3 and is filtered from top to bottom by the fine-pore filter element 203. The filtered water flows downwards and, through the connecting pipe 10 and the centrifugal pump 4, is introduced into the filter tank 5. The threaded sealing cap 201 is threadedly connected to the mounting cylinder 2. Using a wrench 202, the threaded sealing cap 201 is rotated to remove the fine-pore filter element 203 from the bottom of the mounting cylinder 2 for replacement.
[0024] The filter tank 5 is equipped with a filter box 501, and the filter box 501 is integrally provided with an inclined flow surface 502. A guide filter plate 503 is fixedly installed on the surface of the inclined flow surface 502. A filter hole plate 504 is provided at the lower end of the inclined flow surface 502. A lift pump 13 is installed at the bottom of the filter tank 5, and the output end of the lift pump 13 is connected to a water outlet pipe 6. Several filter boxes 501 are arranged vertically and parallel inside the filter tank 5, and the upper and lower layers of filter boxes 501 are arranged in a mirror image. Three sets of guide filter plates 503 are provided on the inclined flow surface 502, and the inclined angle of the guide filter plates 503 on the inclined flow surface 502 is 15 degrees.
[0025] Specifically, centrifugal pump 4 introduces the pre-filtered water from mounting cylinder 2 into filter tank 5. Inside filter tank 5, multiple sets of filter boxes 501 are arranged in parallel. These filter boxes 501 have inclined flow surfaces 502 designed inside. When water flows along the inclined flow surfaces 502, some water permeates through the guide filter plates 503 to the lower guide filter plates 503. At the same time, some water flows along the inclined guide filter plates 503 to the lower guide filter plates 503. Multiple sets of guide filter plates 503 are set on the inclined flow surfaces 502, using the inclined surfaces for multi-stage interception filtration. In addition, the upper and lower filter boxes 501 are arranged in a mirror image. This design allows the water to be repeatedly deflected and filtered during the filtration process until the water flows to the bottom of filter tank 5. This design greatly improves the filtration effect and ensures the purity of the water.
[0026] The output end of the water outlet pipe 6 is connected to a multi-stage filter barrel 9, and the output end of the multi-stage filter barrel 9 is connected to a series booster pump pipe 11 for connecting the multi-stage filter barrels 9 in series. The drain end of the multi-stage filter barrel 9 is connected to a clean water pipe 12. The booster pump 13 is connected to the water outlet pipe 6 by a flange. A valve 7 is installed on the surface of the water outlet pipe 6. A flow meter 8 is installed at the connection between the output end of the water outlet pipe 6 and the series booster pump pipe 11.
[0027] Specifically, the filtered water in the filter tank 5 is introduced into the outlet pipe 6 by the booster pump 13, and the valve 7 is opened. The water flows into the series booster pump pipe 11 through the outlet pipe 6. The series booster pump pipe 11 introduces the water into the multi-stage filter tank 9. The multi-stage filter tank 9 is equipped with multiple stages of filter media, thereby achieving step-by-step filtration. The multi-stage filter tanks 9 are connected in series. With the cooperation of the pipeline and the booster pump, the water can be pushed to flow into the multi-stage filter tank 9 for layer-by-layer permeation filtration.
[0028] The working principle of this utility model is as follows:
[0029] In using this invention, water is first introduced into the mounting cylinder 2 through the inlet pipe 3. The fine-pore filter element 203 inside the mounting cylinder 2 performs preliminary filtration of the water. The water that has undergone preliminary filtration is then pumped into the filter tank 5 by the centrifugal pump 4 through the connecting pipe 10. In the filter tank 5, the water encounters multiple filter boxes 501. The inclined flow surface 502 and the guide filter plate 503 designed inside these filter boxes 501 can effectively intercept and filter the water in multiple stages. When the water flows on the inclined flow surface 502, some of the water will permeate through the guide filter plate 503 to the lower guide filter plate 501. At the same time, another part of the water will flow down to the lower layer along the inclined guide filter plate 503. This design allows the water to be repeatedly folded during the filtration process, which greatly improves the filtration effect. The water filtered by the filter box 501 will flow into the bottom of the filter tank 5, and then be pumped to the outlet pipe 6 by the lift pump 13. In the outlet pipe 6, the water flow rate is controlled by the valve 7 and measured by the flow meter 8. Then it is introduced into the series booster pump pipe 11. The series booster pump pipe 11 sends the water into the multi-stage filter tank 9 for step-by-step permeation filtration, and finally achieves deep purification of the water quality.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
