Description

Technical Field

[0001] The present invention relates to the technical field of ceramic pumps, and more specifically, to a ceramic pump with reduced impurity damage. Background Art

[0002] Ceramic pumps are made of ceramic materials with excellent corrosion resistance and wear resistance. The pump body and pump cover are made of acid-resistant ceramics. Ceramic pumps for chemical industry are generally centrifugal pumps, and their impellers, volutes, shaft seal chambers, and suction and discharge pipes are all made of ceramics. At present, alumina ceramics are mainly used; they are suitable for conveying highly corrosive liquids such as hydrochloric acid, sulfuric acid, and nitric acid, but cannot convey fluorine-containing materials and concentrated alkali solutions.

[0003] During the operation of the ceramic pump, impurities are inevitably present in the fluid to be extracted. In order to reduce the damage to the ceramic pump caused by impurities in the fluid to be extracted, the prior art will add a filtering device to the ceramic pump. As the work progresses, a lot of impurities will gradually accumulate on the filtering device. In order not to affect the normal filtration and the normal operation of the ceramic pump, the prior art will add a switching device to the filtering device. The switching device is used to switch between multiple filtering devices to ensure the filtering effect. However, the switching is not smart enough and cannot be switched in real time according to the filtering status. If the switch is too early, the filtering device has not fully worked. If the switch is too late, the fluid flow rate will be too slow and the workload of the ceramic pump will be increased. For example, the "filter mechanism" recorded in an improved anti-corrosion silicon carbide ceramic pump in the prior art (authorization announcement number CN117072489B) is only switched by a "pushing rod", and it cannot be switched in real time according to the filtering status.

[0004] Therefore, the present application proposes a ceramic pump with reduced impurity damage to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art: the switching of the switching device in the prior art is not intelligent enough and cannot be switched timely according to the filtering status in real time. If the switch is too early, the filtering device has not fully worked. If the switch is too late, the fluid flow rate will be too slow and the work of the ceramic pump will be increased. A ceramic pump with reduced impurity damage is proposed.

When the ceramic pump body starts working, the fluid first enters the feed pipe, and then enters the filter rotating table inside the filter device along the feed pipe, and then is introduced into the wedge-shaped surface through the water guide cavity, and then filtered through multiple filter holes; the impurities filtered by the filter holes will gradually accumulate on the wedge-shaped surface.

[0012] In the detailed technical solution of the present invention, a self-cleaning filter assembly is laid on the wedge-shaped surface, and the self-cleaning filter assembly includes a supporting filter element and a plurality of movable filter elements, and the plurality of movable filter elements are rotatably assembled on the supporting filter element; the plurality of movable filter elements are connected by a connecting belt, and a plurality of steel wires are laid inside the connecting belt.

[0013] Furthermore, the movable filter element includes a positioning frame, inside which a filter plate is installed; the positioning frame is rotatably equipped with a rotating plate on both sides of the end of one end, and the rotating plate is fixed on the supporting filter element; the positioning frame is fixed with multiple springs on both sides of its middle position, and the other end of the spring is connected to the supporting filter element.

[0014] Furthermore, the supporting filter element includes an outer frame, and a plurality of inserted pins are fixed inside the outer frame, and the plurality of inserted pins are distributed in an array inside the outer frame.

[0015] During the process of fluid entering the filter rotating table, since one end of the positioning frame on the movable filter element is rotatably connected, and multiple springs are fixed on both sides of the middle position, when impurities rush towards the supporting filter element and multiple movable filter elements along with the high-speed flowing fluid, the movable filter element will use multiple springs for elastic buffering, thereby reducing the impact of impurities on the filter device and improving the service life; when the impurities are large and have a strong impact force, the movable filter element is buffered to a low level, the movable filter element is attached to the supporting filter element, and multiple piercing nails will pierce the movable filter element to crush the impurities, thereby improving the service life on the basis of reducing the impact of impurities on the filter device; in the process of impurities filtered by the movable filter element gradually accumulating, the power of the ceramic pump body is periodically adjusted, so that the movable filter element is periodically attached to the supporting filter element, and multiple piercing nails on the supporting filter element are used to clean up the garbage stuck on the movable filter element, and pierce the garbage accumulated on the movable filter element, thereby improving the fluid pass rate and achieving self-cleaning.

[0016] In the detailed technical scheme of the present invention, a knocking assembly is installed inside the filter assembly, and the knocking assembly is used to clean impurities stuck on the self-cleaning filter assembly; the knocking assembly includes a guide frame and multiple knocking heads, and the multiple knocking heads are slidably assembled on the guide frame; a screw rod is rotatably assembled on the guide frame, and the screw rod is distributed along the main body of the guide frame; the screw rod passes through the multiple knocking heads in turn and is threadedly matched with the multiple knocking heads; a forward and reverse motor is installed at the end of the guide frame, and the output end of the forward and reverse motor is fixed at the end of the screw rod.

[0018] After filtering, the self-cleaning filter component with accumulated impurities rotates to the inside of the filter component. When it enters the area that does not need to be filtered, the forward and reverse motors are used to drive the screw rod, and the multiple knocking heads are transmitted by the screw rod periodically, so that the multiple knocking heads are prompted to perform periodic reciprocating motion along the guide frame. In this process, the knocking ball is driven by the electric telescopic rod to knock on the movable filter element, so that the movable filter element is periodically fitted to the supporting filter element, so that multiple piercing nails pierce the movable filter element, and the impurities stuck on the movable filter element are broken, so as to achieve efficient cleaning of stubborn impurities on the movable filter element and improve the subsequent working effect of the movable filter element.

[0019] Compared with the prior art, the impurity damage-reducing ceramic pump of the present invention has the following advantages:

[0020] 1. When the ceramic pump body starts working, the fluid first enters the inside of the feed pipe, and then enters the filter rotating table inside the filter device along the feed pipe, and then is introduced into the wedge surface through the water guide cavity, and then filtered through multiple filter holes; the impurities filtered by the filter holes will gradually accumulate on the wedge surface. In this process, the force of the fluid on the wedge surface will gradually increase. After the impurities accumulate to a critical value, the friction balance of the filter rotating table rotating assembly inside the shell is broken, and the fluid will use the wedge surface to drive the filter rotating table to rotate, and switch the unit filter table with accumulated impurities to the unused unit filter table, so as to realize the real-time timely switching of multiple unit filter tables according to the filtering status, so as to ensure the filtering effect; avoid the switching is not intelligent enough, resulting in the filter device not working fully when switching too early, and the switching too late will cause the fluid flow rate to be too slow and increase the workload of the ceramic pump;

[0021] Second, when the water-guiding cavity faces a part of a unit filter station, the fluid will continue to flow to the local wedge-shaped surface of the unit filter station for filtering; in the process of impurities gradually accumulating on the wedge-shaped surface, the force of the fluid on the wedge-shaped surface will gradually increase, and gradually overcome the elastic restoring force of the spring, prompting the unit filter station to drive the wedge-shaped surface to gradually move forward, so as to adjust the filtering position in time according to the filtering state locally, and switch multiple unit filter stations in time according to the filtering state in real time overall, so as to achieve timely adjustment in real time according to the filtering state from local to overall, so as to fully ensure the filtering effect;

[0022] 3. When the fluid enters the filter rotating table, since one end of the positioning frame on the movable filter element is rotatably connected, and multiple springs are fixed on both sides of the middle position, when impurities rush to the supporting filter element and multiple movable filter elements with the high-speed flowing fluid, the movable filter element will use multiple springs for elastic buffering, reducing the impact of impurities on the filter device and prolonging its service life;

[0023] At the same time, when the impurities are large and have a strong impact, the movable filter element is buffered to the bottom, the movable filter element is attached to the supporting filter element, and multiple inserted nails will pierce the movable filter element to break the impurities, thereby reducing the impact of impurities on the filter device and increasing its service life;

[0024] As impurities filtered by the active filter gradually accumulate, the power of the ceramic pump body is periodically adjusted to ensure that the active filter periodically fits onto the supporting filter, so that multiple inserted nails on the supporting filter can clean up the garbage stuck on the active filter and puncture the accumulated garbage on the active filter, thereby increasing the passing rate of the fluid and achieving self-cleaning.

[0025] 4. After filtering, the self-cleaning filter component with accumulated impurities rotates to the inside of the filter component. When it enters the area that does not need to be filtered, the forward and reverse motors are used to drive the screw rod, and the multiple knocking heads are transmitted through the periodic threads of the screw rod, so that the multiple knocking heads are prompted to perform periodic reciprocating motions along the guide frame. During this process, the knocking ball is driven by the electric telescopic rod to knock on the movable filter element, so that the movable filter element is periodically fitted to the supporting filter element, so that multiple piercing nails pierce the movable filter element, and the impurities stuck on the movable filter element are broken, so as to achieve efficient cleaning of stubborn impurities on the movable filter element and improve the subsequent working effect of the movable filter element.

[0046] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] In the embodiment of the present invention, refer to Figure 1 : A ceramic pump with reduced impurity damage, comprising a ceramic pump body 3, wherein a filter device 7 is installed inside a feed pipe 6 installed on the ceramic pump body 3, and the filter device 7 is used to filter the fluid passing through;

[0048] It is necessary to further explain that: the components not described in the ceramic pump body 3 are prior art, and their detailed structures can be learned from existing literature journals, and can also be directly purchased on the market, or can be assembled from components purchased on the market, etc.; they are not to be protected by the present invention, and are not explained in detail here, nor are they drawn in the drawings;

[0049] See also Figure 2-Figure 4 : The filter device 7 has a filter assembly 100 installed therein, the filter assembly 100 includes a housing, a filter rotating platform 200 is rotatably mounted inside the housing, the filter rotating platform 200 includes a plurality of unit filter platforms 230, and the plurality of unit filter platforms 230 are distributed in a circular array; a water guide cavity 300 is opened on the housing on one side of the filter rotating platform 200, and the water guide cavity 300 faces the unit filter platform 230;

[0050] The unit filter platform 230 is provided with a spiral wedge-shaped surface 231 on the side facing the water guide cavity 300, and a plurality of through-shaped filter holes 232 are provided on the unit filter platform 230;

[0051] The fluid entering the feed pipe 6 is introduced to the wedge surface 231 through the water guiding cavity 300 and then filtered through the plurality of filter holes 232 .

[0052] Therefore, in view of the prior art, a filter device will be added to the ceramic pump. As the work accumulates day by day, a lot of impurities will gradually accumulate on the filter device. In order not to affect the normal filtration and the normal operation of the ceramic pump, the prior art will add a switching device to the filter device. The switching device is used to switch multiple filter devices to ensure the filtering effect; however, its switching is not smart enough and cannot be switched in time according to the filtering status in real time. If the switch is too early, the filter device has not fully worked. If the switch is too late, the fluid flow rate will be too slow and the work of the ceramic pump will be increased. The present application can achieve:

[0053] When the ceramic pump body 3 starts working, the fluid first enters the feed pipe 6, and then enters the filter rotating table 200 inside the filter device 7 along the feed pipe 6, and then is introduced into the wedge surface 231 through the water guide cavity 300, and then filtered through multiple filter holes 232; the impurities filtered by the filter holes 232 will gradually accumulate on the wedge surface 231. During this process, the force of the fluid on the wedge surface 231 will gradually increase. After the impurities accumulate to a critical value, the friction balance of the filter rotating table 200 rotating and assembled inside the shell is broken (it should be noted here that the magnitude of the friction force can be adjusted by adjusting the pressure or the friction coefficient, and the pressure adjustment can be achieved by the electric cylinder extending and retracting to drive the abutment of the abutment block The friction coefficient can be adjusted by controlling a plurality of protrusions on the rotating surface through a hydraulic cylinder to adjust the roughness; the roughness is used to adjust the friction coefficient; at the same time, a pressure sensor is installed inside the water guide cavity 300 to flexibly control the adjustment of the friction force), the fluid will use the wedge surface 231 to drive the filter rotating table 200 to rotate, and the unit filter table 230 with accumulated impurities will be switched to the unused unit filter table 230, so as to realize the real-time switching of multiple unit filter tables 230 according to the filtering status in time to ensure the filtering effect; avoid the switching being not intelligent enough, resulting in the switching too early and the filtering device not fully working, and the switching too late will cause the fluid flow rate to be too slow and increase the workload of the ceramic pump.

[0054] In the embodiment of the present invention, refer to Figure 2 : The water guiding cavity 300 faces one or more unit filter stations 230; a plurality of unit filter stations 230 are distributed in a circular array around the support plate 220 and are connected end to end in sequence;

[0055] A positioning shaft 210 is fixed at one end of the support plate 220, and the positioning shaft 210 is rotatably assembled inside the positioning tube 400; an elastic rotating shaft 240 is fixed at the other end of the support plate 220, and the columnar center lines of the positioning shaft 210, the support plate 220 and the elastic rotating shaft 240 are all on the same straight line.

[0056] For further information, see Figure 2 , Figure 3 and Fig.13 : The elastic shaft 240 is assembled inside the shell; the elastic shaft 240 includes an outer rotating cylinder 241 and an inner rotating shaft 242, the inner rotating shaft 242 is assembled inside the shell, and the outer rotating cylinder 241 is movably sleeved outside the inner rotating shaft 242;

[0057] A plurality of slide grooves 243 are provided around the outer periphery of the inner rotating shaft 242, and the plurality of slide grooves 243 are distributed in a circular array along the inner rotating shaft 242;

[0058] A plurality of inner push plates 244 are fixed inside the outer rotating cylinder 241, and the plurality of inner push plates 244 correspond to the plurality of slide grooves 243 in a one-to-one manner; the inner push plates 244 are movably inserted into the slide grooves 243, and a plurality of springs 245 are fixed on both sides of the inner push plates 244, and the springs 245 are connected to the interior of the slide grooves 243 at one end away from the inner push plates 244.

[0059] Therefore, it can be known from the above situation that: when the water guiding cavity 300 faces a part of a unit filter stage 230, the fluid will continue to flow to the local wedge-shaped surface 231 of the unit filter stage 230 for filtering; in the process of impurities gradually accumulating on the wedge-shaped surface 231, the force of the fluid on the wedge-shaped surface 231 will gradually increase, and gradually overcome the elastic restoring force of the spring 245 (at this time, the elastic restoring force is less than the friction force of the filter rotating stage 200 rotating and assembled inside the shell), so that the unit filter stage 230 drives the wedge-shaped surface 231 to gradually move forward, so as to adjust the filtering position timely according to the filtering state locally, and switch multiple unit filter stages 230 timely according to the filtering state in coordination with the overall real-time real-time adjustment, so as to achieve hierarchical real-time timely adjustment according to the filtering state from local to overall, so as to fully ensure the filtering effect.

[0060] In the embodiment of the present invention, refer to Figure 1 : The impurity damage reducing ceramic pump also includes a reduction motor 2, which is powered by a reduction motor 2 mounted on a ceramic pump body 3, and is powered by a reduction motor 2 connected to a drive motor 1, and both the drive motor 1 and the reduction motor 2 are mounted on a base 4, and a discharge pipe 5 is installed on the ceramic pump body 3.

[0061] It needs to be further explained that: the reduction motor 2 and the drive motor 1, as well as the power supply and wiring methods of the reduction motor 2 and the drive motor 1 are all existing technologies, and their detailed structures can be found in existing literature journals, and can also be purchased directly on the market, or parts can be purchased on the market to assemble them, etc.; they are not what the present invention wants to protect, so they will not be explained in detail here, nor are they drawn in the accompanying drawings.

[0062] In the embodiment of the present invention, refer to Figure 1 : The filtering device 7 comprises a positioning housing, which comprises two symmetrically distributed half shells, and the two half shells are connected by a locking flange assembly 8;

[0063] The locking flange assembly 8 comprises a flange and a plurality of bolts, wherein the flange is fixed at a single opening of the half shell; and the plurality of bolts are used to detachably lock the two half shells together.

[0064] In the embodiment of the present invention, refer to Figure 5 and Figure 6: A self-cleaning filter assembly 500 is laid on the wedge-shaped surface 231, and the self-cleaning filter assembly 500 includes a supporting filter element 520 and a plurality of movable filter elements 510, and the plurality of movable filter elements 510 are rotatably assembled on the supporting filter element 520; the plurality of movable filter elements 510 are connected by a connecting belt, and a plurality of steel wires are laid inside the connecting belt.

[0065] For further information, see Figure 5 , Figure 6 and Figure 8 : The movable filter element 510 includes a positioning frame 511, and a filter plate 512 is installed inside the positioning frame 511; the positioning frame 511 is rotatably equipped with a rotating plate 514 on both sides of the end of one end, and the rotating plate 514 is fixed on the supporting filter element 520; the positioning frame 511 is fixed with multiple springs 513 on both sides of the middle position, and the other end of the spring 513 is connected to the supporting filter element 520.

[0066] See also Figure 5-Figure 7 The supporting filter element 520 includes an outer frame 521 , and a plurality of inserted pins 522 are fixed inside the outer frame 521 . The plurality of inserted pins 522 are distributed in an array inside the outer frame 521 .

[0067] Therefore, it can be known from the above situation that: when the fluid enters the filter rotating table 200, since one end of the positioning frame 511 on the movable filter element 510 is rotatably connected, and multiple springs 513 are fixed on both sides of the middle position, when impurities rush toward the supporting filter element 520 and multiple movable filter elements 510 along with the high-speed flowing fluid, the movable filter element 510 will use multiple springs 513 for elastic buffering, thereby reducing the impact of impurities on the filter device and increasing the service life;

[0068] At the same time, when the impurities are large and have a strong impact, the movable filter 510 is buffered to the bottom, and the movable filter 510 is attached to the supporting filter 520 (for details, please refer to Fig. 9 ), multiple piercing nails 522 will pierce the movable filter element 510 to crush the impurities, thereby reducing the impact of the impurities on the filter device and increasing its service life;

[0069] As impurities filtered by the movable filter element 510 gradually accumulate, the power of the ceramic pump body 3 is periodically adjusted to ensure that the movable filter element 510 is periodically fitted onto the supporting filter element 520, so that the multiple inserted nails 522 on the supporting filter element 520 can clean the garbage stuck on the movable filter element 510 and puncture the garbage accumulated on the movable filter element 510, thereby improving the fluid passing rate and achieving self-cleaning.

[0070] In the embodiment of the present invention, refer to Figure 2 , Fig.10 and Fig.11 : A knocking assembly 600 is installed inside the filter assembly 100, and the knocking assembly 600 is used to clean impurities stuck on the self-cleaning filter assembly 500.

[0071] The knocking assembly 600 includes a guide frame 630 and a plurality of knocking heads 640, wherein the plurality of knocking heads 640 are slidably mounted on the guide frame 630; a screw rod 620 is rotatably mounted on the guide frame 630, and the screw rod 620 is distributed along the main body of the guide frame 630; the screw rod 620 sequentially passes through the plurality of knocking heads 640, and is threadedly coupled with the plurality of knocking heads 640;

[0072] The guide frame 630 is provided with a forward and reverse motor 610 at its end, and the output end of the forward and reverse motor 610 is fixed at the end of the lead screw 620 .

[0073] For further information, see Fig.11 and Fig.12 The striking head 640 includes a guide slider 642, which has two guide grooves 643. The guide slider 642 is slidably assembled on the guide frame 630 through the two guide grooves 643. The guide frame 630 is provided with an anti-falling convex edge; a threaded hole is provided on the guide slider 642, and the screw rod 620 is threadedly inserted into the guide slider 642;

[0074] A plurality of telescopic rods 641 are inserted and fixed on the guide slider 642 . The telescopic rods 641 include electric telescopic rods and knocking balls. The electric telescopic rods are inserted and fixed on the guide slider 642 , and the knocking balls are fixed at the ends of the electric telescopic rods.

[0075] Therefore, it can be known from the above situation that: when the self-cleaning filter component 500 with accumulated impurities after filtration rotates to the inside of the filter component 100 and enters the area that does not need to be filtered, the forward and reverse motor 610 is used to drive the screw rod 620, and the multiple knocking heads 640 are periodically threaded through the screw rod 620, so that the multiple knocking heads 640 are prompted to perform periodic reciprocating motion along the guide frame 630. During this process, the knocking ball is driven by the electric telescopic rod to knock on the movable filter element 510, so that the movable filter element 510 is periodically fitted to the supporting filter element 520, so that the multiple inserted nails 522 pierce the movable filter element 510, and the impurities stuck on the movable filter element 510 are broken, so as to achieve efficient cleaning of the stubborn impurities on the movable filter element 510 and improve the subsequent working effect of the movable filter element 510.
