Description

Technical Field

[0001] The present invention relates to the field of submersible pumps, in particular to a submersible pump which is convenient for separating particles and water. Background Art

[0002] Hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, as well as in water extraction projects such as rivers, reservoirs, and canals. They are mainly used for farmland irrigation and water supply for people and livestock in mountainous areas.

[0003] Because water sources such as underground, rivers, reservoirs, and canals contain large amounts of silt, rocks, and other materials, existing technologies, such as those in Chinese patent applications CN208778266U, CN208778266U, and CN 105271465B, use methods such as mixing, ultrasonic, and chemical crushing to break up particles before pumping them out together with the submersible pump. However, these particles are discharged together with water from the submersible pump's outlet, which can easily clog the pump.

[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to design a submersible pump that is convenient for separating particles and water. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a submersible pump that facilitates the separation of particulate matter and water, which can effectively solve at least one problem existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A submersible pump for facilitating separation of particles and water, comprising:

[0008] Pump body;

[0009] a stone crushing device, provided at the water inlet end of the pump body, for crushing particles entering the pump body;

[0010] An impurity separator is provided at the water outlet end of the pump body, wherein the interior of the impurity separator includes a clean water flow area and an impurity flow area, wherein the clean water flow area is linearly connected to the inlet of the impurity separator and the outlet of the impurity separator, and the impurity flow area is spirally wound around the outer circle of the clean water flow area, wherein the outer circle of the clean water flow area and the inner circle of the impurity flow area are connected, and water containing impurities is separated into clean water and impurities by centrifugal force in the impurity separator;

[0011] A water outlet mechanism is connected to the outlet of the impurity separator, and the water outlet mechanism includes a clean water outlet and an impurity outlet. The clean water outlet is connected to a position near the outlet of the impurity separator corresponding to the top of the clean water flow area, and the impurity outlet is connected to a position near the outlet of the impurity separator corresponding to the top of the impurity flow area.

[0012] Furthermore, the diameter of the outer circle of the impurity flow zone gradually increases from the inlet of the impurity separator to the outlet of the impurity separator, so that the flow rate of the impurities in the impurity flow zone is slowed down.

[0013] Furthermore, the diameter of the clean water flow area gradually decreases from the inlet of the impurity separator to the outlet of the impurity separator, so that the flow rate of the clean water at the outlet end of the impurity separator increases.

[0014] Furthermore, the impurity flow zone is a double-layer spiral structure, and the difference between the major diameter and the minor diameter of the double-layer spiral structure decreases from the inlet to the outlet of the impurity separator.

[0015] The pitch of the impurity flow region increases from the inlet of the impurity separator toward the outlet of the impurity separator.

[0016] Furthermore, the pitch of the double-layer helical structure decreases from the inlet of the impurity separator to the outlet of the impurity separator.

[0017] Furthermore, the minor diameter of the double-layer spiral structure decreases from the inlet of the impurity separator to the outlet of the impurity separator.

[0018] Furthermore, the stone crushing device includes an ultrasonic cover and an ultrasonic generator. The ultrasonic cover is connected to the water inlet end of the pump body, and the ultrasonic generator is hung in the ultrasonic cover.

[0019] Furthermore, an impurity collection trough is provided at the inlet of the impurity separator.

[0020] Furthermore, the water outlet mechanism passes through a first filter mesh block between the clean water outlet and the impurity outlet, and a second filter mesh is provided at the entrance of the clean water outlet, and the aperture of the first filter mesh is smaller than the aperture of the second filter mesh.

[0021] Furthermore, the second filter screen is arranged to be inclined with respect to the water outlet direction of the clean water outlet.

[0022] Therefore, the present invention provides the following effects and / or advantages:

[0023] This application utilizes ultrasonic pulverization technology to crush debris before it enters the pump impeller. This technology does not damage the pulverizer itself (such as cutters), extending its service life. It physically crushes impurities in the drained water, capable of processing larger particles, and has a high flow rate, making it suitable for rapid drainage applications.

[0024] After physically crushing the impurities in the discharged water, this application can separate the impurities and clean water in the water through a spiral impurity separator. The clean water is discharged through the clean water outlet, and the impurities are discharged through the impurity outlet sewage outlet, which greatly reduces the possibility of water pump blockage, does not require cleaning for a long time, and extends the maintenance interval.

[0025] The present application optimizes the structure of the impurity separator in many places, which can quickly consume the kinetic energy of the impurities and cause them to settle, while compressing the impurities and reducing their volume.

[0026] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0035] refer to Figure 1-6, a submersible pump for facilitating separation of particles and water, comprising:

[0036] Pump body 1;

[0037] A stone crushing device 2 is provided at the water inlet end of the pump body 1 and is used to crush particles entering the pump body 1;

[0038] In this embodiment, the pump body 1 is a submersible pump, and the stone crushing device 2 can be a structure including ultrasound, chemical, blades, etc., so as to crush large particles into small particles.

[0039] Impurity separator 3, reference Figure 2 , arranged at the water outlet end of the pump body 1, the interior of the impurity separator 3 includes a clean water flow area 301 and an impurity flow area 302, the clean water flow area 301 is linearly connected to the inlet of the impurity separator 3 and the outlet of the impurity separator 3, the impurity flow area 302 is spirally wound around the outer circle of the clean water flow area 301, the outer circle of the clean water flow area 301 and the inner circle of the impurity flow area 302 are connected, and the water containing impurities is separated into clean water and impurities by centrifugal force in the impurity separator 3;

[0040] In this embodiment, the impurity separator 3 is one of the core technical features. The pump body 1 outputs water containing impurities into the impurity separator 3. Figure 2 The dotted area represents the impurity flow zone 302, and the dotted horizontal line area represents the clean water flow zone 301. The clean water flow zone 301 is linearly connected to the inlet and outlet of the impurity separator 3, meaning that the clean water flow zone 301 connects the upper and lower ends of the impurity separator 3 in a vertically upward straight line. The outer circle of the clean water flow zone 301 and the inner circle of the impurity flow zone 302 are connected, meaning that there is no structure such as a screen between the clean water flow zone 301 and the impurity flow zone 302, allowing water and impurities to easily flow directly from the clean water flow zone 301 into the impurity flow zone 302.

[0041] The operating principle of this embodiment is as follows: at the inlet of the impurity separator 3, the impurities and water discharged by the pump body 1 possess a certain amount of kinetic energy. Because the impurity flow zone 302 is spirally wound around the outer ring of the clean water flow zone 301, and the two are connected, after entering the impurity separator 3 together, the impurities and water follow a spiral upward flow path and flow beyond the outlet of the impurity separator 3. Since the unit weight of most impurities is greater than the unit weight of water, the centrifugal force causes particles to tend to accumulate on the outer ring of the spiral flow path, while water tends to tend to accumulate on the inner ring of the spiral flow path, thus separating the impurities and clean water.

[0042] Water outlet mechanism 4, reference Figure 3, connected to the outlet of the impurity separator 3, the water outlet mechanism 4 includes a clean water outlet 401 and an impurity outlet 402, the clean water outlet 401 is connected to a position corresponding to the top of the clean water flow area 301 near the outlet of the impurity separator 3, and the impurity outlet 402 is connected to a position corresponding to the top of the impurity flow area 302 near the outlet of the impurity separator 3.

[0043] As explained above, under the action of centrifugal force, particulate matter tends to accumulate on the outer ring of the spiral flow path, while water tends to accumulate on the inner ring of the spiral flow path. At this point, the outlet of the impurity separator 3 is connected to the water outlet mechanism 4, so that clean water can be drawn out from the outlet of the impurity separator 3 at the top of the clean water flow area 301, and impurities can be drawn out from the outlet of the impurity separator 3 at the top of the impurity flow area 302, achieving flow diversion and preventing impurities from clogging the clean water outlet 401.

[0044] Furthermore, the diameter of the outer circle of the impurity flow area 302 gradually increases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3 , so that the flow rate of the impurities in the impurity flow area is slowed down.

[0045] refer to Figure 5 The diameter of the outer ring of the impurity flow zone 302 is R1, and R1 gradually increases from bottom to top. The principle of this setting is that after the pump body 1 outputs water and impurities, when the water and impurities enter the inlet of the impurity separator 3, they have a certain initial kinetic energy. Under the action of the initial kinetic energy and centrifugal force, the impurities spiral upward along the side wall of the impurity separator 3. The diameter of the outer ring of the impurity flow zone 302 gradually increases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3, and the spiral radius of the impurities increases. According to the principle of centrifugal force, after the spiral radius of the impurities increases, the walking speed of the impurities decreases. Therefore, under the action of the spiral structure of the impurity separator 3, the process of the impurities climbing upward gradually converts the initial kinetic energy into centrifugal kinetic energy. After the rotation speed of the impurities decreases, the impurities can no longer spiral upward and are finally deposited in the impurity separator 3.

[0046] Furthermore, the diameter of the clean water flow area 301 gradually decreases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3 , so that the flow rate of the clean water at the outlet end of the impurity separator 3 increases.

[0047] refer to Figure 5 The radius of the clean water flow area 301 is R2. The spiral radius of the clean water in the clean water flow area 301 becomes smaller. Under the action of centrifugal force, the flow speed of the clean water increases, so that it quickly reaches the top of the impurity separator 3 and is separated from the impurities with a slower speed.

[0048] Furthermore, the impurity flow region 302 is a double-layer spiral structure, and the difference between the major diameter and the minor diameter of the double-layer spiral structure decreases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3 .

[0049] refer to Figure 5 The difference between the major diameter and minor diameter of the double-layer spiral structure is represented by D1. As D1 gradually decreases, the centrifugal force of particles and sludge in the rising process can be amplified, so that the impurities consume the kinetic energy of light faster and thus settle.

[0050] The pitch of the impurity flow region 302 increases from the inlet of the impurity separator to the outlet of the impurity separator.

[0051] Furthermore, the pitch of the double-layer helical structure decreases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3 .

[0052] Furthermore, the minor diameter of the double-layer spiral structure decreases from the inlet of the impurity separator 3 to the outlet of the impurity separator 3 .

[0053] refer to Figure 5 The difference in pitch of the double-helical structure is represented by D2, and the minor diameter of the double-helical structure is represented by R3. The space between the two threads of the double-helical structure can serve as an accumulation space for impurities. As the difference between the major and minor diameters of the double-helical structure gradually decreases, the space for impurities is compressed, allowing the impurities to fully rub against the inner wall of the impurity separator 3, losing kinetic energy and thus settling. Furthermore, as the space becomes smaller, the impurities are squeezed, and the moisture in the impurities can be separated from the impurities, reducing the volume and weight of the impurities.

[0054] Furthermore, the lithotripsy device 2 includes an ultrasonic cover 201 and an ultrasonic generator 202 . The ultrasonic cover 201 is connected to the water inlet end of the pump body 1 , and the ultrasonic generator 202 is hung in the ultrasonic cover 201 .

[0055] Furthermore, an impurity collecting trough 303 is provided at the inlet of the impurity separator 3 .

[0056] Furthermore, the water outlet mechanism 4 is blocked by a first filter 403 between the clean water outlet 401 and the impurity outlet 402 , and a second filter 404 is provided at the entrance of the clean water outlet 401 . The aperture of the first filter 403 is smaller than that of the second filter 402 .

[0057] Furthermore, the second filter screen 404 is arranged to be inclined with respect to the water outlet direction of the clean water outlet 401 .

[0058] In this embodiment, the first filter 403 and the second filter 404 are arranged at the discharge outlet of the impurity separator 3, so that clean water can pass through the first filter 403 and the second filter 404 and flow out through the clean water outlet 401, while impurities are filtered out by the first filter 403 and the second filter 404 and flow out from the impurity outlet 402.

[0059] Furthermore, the larger aperture of the second filter 404 in this embodiment increases the area through which clean water flows through the clean water outlet 401, thereby reducing the flow resistance of clean water through the filter. The second filter 404 is tilted relative to the outlet direction of the clean water outlet 401, allowing impurities reaching the second filter 404 to flow along the tilt of the second filter 404 toward the impurity outlet 402, preventing impurities from clogging the surface of the second filter 404. Simultaneously, as impurities flow through the impurity outlet 402, they are filtered by the first filter 403, allowing the majority of the clean water to escape from the impurities and flow into the clean water outlet 401.
