Description

Technical Field

[0001] The invention belongs to the technical field of delivery pumps, and in particular relates to an impeller and a delivery pump with anti-blocking function. Background Art

[0002] A delivery pump is a device used to transport liquids or other materials. It uses mechanical force to transport materials from one place to another. There are many types of delivery pumps. In the prior art, a liquid pump refers to an instrument with an inlet and an outlet for water inlet and a drain outlet, which can continuously form a vacuum or negative pressure at the inlet; a large output pressure is formed at the drain outlet; the working medium is water or other liquids; and it is a small instrument mainly used in water treatment, environmental protection, medical treatment, industrial control, scientific research laboratories, etc. It can be widely used for lifting, transfer, pressurization, spraying, spraying, water circulation, transportation, etc.

[0003] The blockage of the delivery pump is a common operation problem, which may be caused by a variety of reasons. The pump and pipeline need regular maintenance and cleaning after long-term use. If the maintenance is neglected, the accumulated impurities, corrosion or dirt will also cause blockage. Therefore, it is very important to know how to prevent the blockage of the delivery pump.

[0004] For example, a Chinese invention patent with announcement number CN214007430U discloses an anti-blocking device for use in a low-temperature environment for a delivery pump. By providing a rotating ring, when the delivery pump is delivering liquid, the left filter screen and the right filter screen can filter out debris in the liquid to prevent the delivery pump from being blocked by debris contained in the liquid. During the delivery process, the servo motor drives the rotating ring to rotate, so that the inner scraper in the rotating ring scrapes the debris filtered out from the surface of the left filter screen and the right filter screen to prevent the filtered debris from adhering to the surface of the left filter screen and the right filter screen for a long time and causing the left filter screen and the right filter screen to be blocked, thereby further improving the working efficiency of the delivery pump.

[0005] However, in the process of filtering debris, the rotating ring rotates to remove the debris on the surface of the filter, but some of the debris will be embedded in the aperture of the filter, which is not convenient to scrape off. The filter needs to be knocked to shake off the debris embedded in the aperture of the filter to ensure the filtering effect of the filter, but the knocking process is very cumbersome and cannot be sustained.

[0006] In summary, there is a need for an anti-blocking delivery pump that can continuously clean the filter during operation. Summary of the invention

[0007] The purpose of the present invention is to provide an impeller and a delivery pump with anti-blocking function. The device is provided with an anti-blocking filter assembly, and the motor continuously hits the filter plate through the rotating shaft with the cam to knock down the debris in the aperture of the filter plate, so as to ensure the filtering effect of the filter plate in subsequent work.

[0008] The technical solution adopted by the present invention to solve the above problem is: an impeller and a delivery pump with anti-blocking function, comprising: A bottom plate, a pump body is installed on the top of the bottom plate, a material storage box is installed on the top of the bottom plate, the top of the material storage box is connected to a box body, and an anti-blocking filter component is installed inside the box body; The anti-blocking filter assembly includes a filter plate, a cam is abutted on the surface of the filter plate, a rotating shaft is connected through the interior of the cam, one end of the rotating shaft is rotatably connected to the back of the inner wall of the box, and one end of the rotating shaft is also fixedly connected to a motor.

[0009] The bottom plate is usually a flat and solid plate-like structure located at the bottom of the entire delivery pump. As the base of the entire delivery pump, the bottom plate provides a stable support and installation platform to carry the pump body, storage box and other components.

[0010] The pump body is mounted on top of the base plate and contains the impeller, bearings and other mechanical parts.

[0011] The material storage box is installed on the top of the bottom plate to store the cleaned waste material and prevent larger particles or impurities from entering the pump body, thus avoiding clogging.

[0012] The anti-clogging filter assembly includes a filter plate, a cam and a rotating shaft, which can prevent larger particles or impurities from entering the pump body, thereby avoiding clogging.

[0013] The filter plate has holes or screens installed inside the box. It can filter impurities and larger particles from the water, ensuring that only materials suitable for conveying enter the pump body.

[0014] The cam is installed on the surface of the filter plate, and a rotating shaft is connected inside. Driven by the rotating shaft, the cam rotates or swings, thereby vibrating or moving the filter plate to prevent impurities from accumulating on the filter plate. As a mechanical element, the cam can convert rotational motion into linear motion or intermittent motion through its special shape and movement mode. The cam has an eccentric structure and can continuously knock the filter plate during rotation to remove impurities. The cam base is usually a solid body in the shape of a disk or a cylinder, which is installed on the rotating shaft. The material of the base is generally metal, such as steel or aluminum alloy, to ensure that it has sufficient rigidity and wear resistance. The cam provides a basic shape and support for assembling the eccentric part and connecting the rotating shaft. The eccentric part is a curve or convex part that is offset relative to the center of the cam base. Its eccentricity (i.e., the offset distance) determines the amplitude and frequency of the cam movement. Through the eccentric design, when the cam rotates, the eccentric part will periodically apply force to the filter plate to move or vibrate it. There is usually a hole in the center of the cam for fixed connection with the shaft to ensure that the cam can rotate with the shaft. The connection hole may be fixed by a keyway or a fastening screw, which can provide a stable connection so that the cam can effectively transmit the rotational motion of the motor. When the eccentric part of the cam rotates to the position of contacting the filter plate, it will apply a momentary knocking force to the filter plate. This knocking force can cause the filter plate to produce a short displacement or vibration, thereby shaking off the impurities accumulated on the filter plate.

[0015] The motor is fixedly connected to one end of the box body and is connected to the rotating shaft. The motor provides driving force by clicking, and drives the movement of the cam and the filter plate through the rotating shaft to ensure that the filter plate can effectively prevent clogging.

[0016] A further preferred technical solution is that: a scraping component is slidably connected to the filter plate; The scraping assembly includes a scraper, one side of which abuts against the surface of the filter plate, a sliding plate is fixedly connected to the scraper, an abutment rod is fixedly connected to the upper part of the scraper, an inclined groove is opened on the inner wall of the box, and the abutment rod is arranged inside the inclined groove.

[0017] Among them, the scraper is a flat and hard plate-like structure, one side of which is in contact with the surface of the filter plate. The scraper slides on the surface of the filter plate to scrape and clean the impurities accumulated on the filter plate to ensure that the filter plate remains clean.

[0018] The slide is a sliding element mounted on the scraper, usually made of low friction material such as plastic or metal. The slide enables the scraper to slide smoothly on the surface of the filter plate, reducing the friction between the scraper and the filter plate and improving the movement efficiency of the scraper.

[0019] The abutment rod is a long rod-shaped structure installed on the scraper, and the other end interacts with the inclined groove on the inner wall of the box. The abutment rod guides the scraper to slide regularly on the surface of the filter plate through the guidance of the inclined groove.

[0020] The inclined groove is an inclined track or groove opened on the inner wall of the box. The inclined groove provides a guide for the abutment rod, so that the scraper slides on the surface of the filter plate according to a predetermined path to ensure the effective scraping action.

[0021] The scraper assembly utilizes the temporary displacement of the filter plate. When the system is running, the contact rod moves in the chute due to the temporary displacement of the filter plate. Due to the inclined design of the chute, the scraper will slide or swing periodically along the surface of the filter plate. During the sliding process of the scraper on the surface of the filter plate, the impurities accumulated on the filter plate will be further scraped off, and the impurities will be removed by vibration to prevent the impurities from clogging the holes of the filter plate.

[0022] A further preferred technical solution is that an impeller is installed inside the pump body, and a delivery pipe is connected to the pump body via a flange.

[0023] The impeller is usually a rotating part with multiple blades, which is axially mounted inside the pump body. The impeller can be made of metal or high-strength plastic, and its shape and number of blades are designed according to the specific application. The impeller blades can be straight blades, curved blades or other special shapes to optimize fluid dynamics. The impeller converts mechanical energy into fluid power through rotational motion, pushing the material (liquid or slurry) from one side of the pump body to the other side.

[0024] The pump body is the outer shell of the pump, usually made of metal (cast iron, stainless steel, etc.), with channels designed inside to accommodate the impeller and fluid. The pump body also includes a structure to support the impeller bearings. The pump body has an inlet at one end and a discharge at the other end, which are connected to the delivery pipe through a flange.

[0025] A flange is a disc-shaped connector, usually made of metal, with multiple bolt holes, used to connect the pump body to the delivery pipe. The shape and size of the flange are designed according to standards (such as ANSI, DIN, etc.). The flange is used with a gasket to ensure the sealing of the connection. The flange is used to connect the pump body and the delivery pipe, providing a convenient and stable connection method, which is easy to disassemble and maintain.

[0026] The delivery pipe is a pipe used to transport fluids, usually made of metal (steel, stainless steel, etc.) or plastic (PVC, PE, etc.). The diameter and length of the pipe are designed according to the delivery requirements, and the delivery pipe is connected to the pump body through a flange.

[0027] A further preferred technical solution is that a raising seat is installed at the bottom of the pump body, and the bottom of the raising seat is fixedly connected to the top of the base plate.

[0028] The pad is a bottom support structure, usually made of a solid metal material (such as steel). The design of the pad can be a simple frame or a solid block, depending on the actual needs. The pad can reduce the vibration generated by the periodic sliding or swinging operation of the filter plate surface to a certain extent, protecting the pump body and the ground.

[0029] A further preferred technical solution is that a mounting seat is installed at the bottom of the motor, and the mounting seat is fixedly connected to the box body.

[0030] A further preferred technical solution is that a drawer is slidably connected to the interior of the storage box, and a handle is fixedly connected to the drawer.

[0031] A further preferred technical solution is that: a guide groove for the sliding plate to move is provided on the filter plate.

[0032] A further preferred technical solution is that: the surface of the scraper is provided with a chamfer.

[0033] Among them, chamfering refers to intentionally processing a bevel or fillet on the edge of a blade or edge to reduce the sharpness of the sharp edge. Chamfers are usually cut or ground at a certain angle (such as 45 degrees). The chamfers set on the scraper surface are usually set at the leading edge of the scraper or the edge part that contacts the surface of the filter plate. Chamfers can reduce the friction between the scraper and the surface of the filter plate, reduce wear, and thus extend the service life of the scraper and the filter plate. Chamfers make the contact surface of the scraper smoother when it contacts the surface of the filter plate, and the effect of scraping off impurities is better. The chamfer design can more effectively scrape off impurities accumulated on the surface of the filter plate.

[0034] A further preferred technical solution is that a mounting groove is provided at the top of the box body, a connecting groove is provided at the bottom of the box body, the top and bottom of the filter plate are respectively slidably arranged inside the mounting groove and the connecting groove, guide rods are installed inside the mounting groove and the connecting groove, and the guide rods are arranged through the interior of the filter plate.

[0035] A further preferred technical solution is that: a spring rod is fixedly connected to the filter plate, and the spring rod is fixedly connected to the inner wall of the mounting groove and the connecting groove respectively.

[0036] In summary, the present invention has the following benefits: 1. The present invention provides an anti-blocking filter component and a scraping component. After the material passes through the box, the debris will be filtered out by the filter plate. After the conveying is completed, the motor is started. The motor drives the cam to continuously hit the filter plate through the rotating shaft. Under the action of the spring rod, the filter plate moves back and forth in the horizontal direction to knock down the debris in the aperture of the filter plate to ensure the filtering effect of the filter plate in subsequent work. At the same time, during the movement of the filter plate, the abutment rod is acted upon by the inclined groove and the sliding plate, and drives the scraper to move up and down along the surface of the filter plate to scrape off the debris on the surface of the filter plate to ensure that the debris on the surface of the filter plate and the debris embedded in the aperture of the filter plate can be filtered out, thereby improving the filtering effect of the filter plate.

[0037] 2. The present invention provides a scraping assembly, and when the filter plate moves back and forth, the debris in the aperture of the filter plate and the debris on the surface of the filter plate are scraped off, and the debris falls into the interior of the storage box through the connecting groove. After the debris on the surface of the filter plate is cleaned, the motor is turned off, the drawer in the storage box is opened, and the debris is poured out, making it more convenient for the device to deal with the debris.
