Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to an automatic cleaning device for a horizontal screw centrifuge. Background Technology

[0002] Horizontal screw centrifuges, a highly efficient solid-liquid separation device, are widely used in chemical, food, and environmental protection fields. Their core function is to achieve continuous material separation through a high-speed rotating drum and a screw feeder. However, during long-term operation, scale buildup can easily accumulate inside the drum, affecting separation efficiency and equipment lifespan. Announcement No. CN214077286U discloses a self-cleaning device for horizontal screw centrifuges, relating to the field of horizontal screw centrifuge technology. The device includes a base and a horizontal screw centrifuge body, with the centrifuge body fixedly mounted on the top of the base. The device is characterized by: electric push rods fixedly mounted on both sides of the top of the base; water tanks fixedly mounted on the tops of the two electric push rods; four sleeves fixedly mounted on the bottom of the water tanks; a disc mounted on the bottom of each sleeve; ball bearings fixedly mounted on the outer wall of each disc; and the outer wall of each ball bearing fixedly connected to the inner wall of the sleeve. This invention connects a rotating shaft and a disc body, utilizing a motor, gears, and belts to drive the shaft to rotate within a sleeve. The nozzles on the disc body rotate with the shaft, and an electric push rod moves the water tank up and down. Compared to existing technologies, the nozzles can rotate while adjusting their height, allowing water to be fully sprayed inside the decanter centrifuge, resulting in better cleaning. No manual operation is required. While this invention, with its electric push rod, water tank, and sleeve, allows the nozzles to rotate while adjusting their height, ensuring ample water coverage and improved cleaning, it faces challenges in precisely adapting to different sizes and lengths of decanter centrifuges. This difficulty in achieving stable clamping and positioning leads to equipment wobbling during cleaning, affecting cleaning efficiency and potentially causing damage due to instability. Improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: an automatic cleaning device for a horizontal screw centrifuge, comprising a base, a sliding rod seat, a threaded rod seat, and a distance control motor fixedly installed on the surface of the base, a distance control threaded rod fixedly installed at the output end of the distance control motor, a distance control moving block threadedly connected to the surface of the distance control threaded rod, a fixed clamping seat fixedly installed on the upper surface of the base, a telescopic rod frame fixedly installed on the surface of the distance control moving block, an electric telescopic rod fixedly installed on the surface of the telescopic rod frame, a movable clamping seat fixedly installed at the output end of the electric telescopic rod, a clamping mechanism fixedly installed on the surface of the clamping seat, a cleaning motor fixedly installed on the surface of the threaded rod seat, a cleaning threaded rod fixedly installed at the output end of the cleaning motor, a cleaning sliding rod fixedly installed inside the sliding rod seat, a cleaning threaded seat threadedly connected to the surface of the cleaning threaded rod, a movable plate fixedly installed on the surface of the cleaning threaded seat, and a cleaning sliding rod seat fixedly installed on the surface of the movable plate.

[0005] Preferably, the clamping mechanism includes a clamping motor, a clamping threaded rod, a clamping arm, a rubber groove, and a rubber pad. The output end of the clamping motor is fixedly mounted with the clamping threaded rod, and the surface of the clamping threaded rod is threadedly connected to the clamping arm. The surface of the clamping arm has a rubber groove, and the surface of the rubber groove is fixedly mounted with a rubber pad. This achieves stable clamping of the horizontal decanter centrifuge components. The rubber groove and rubber pad increase the friction of the clamping surfaces, effectively preventing displacement or slippage of the components during cleaning, ensuring safe and stable cleaning operations, avoiding direct contact between the clamping arm and the components, reducing wear and scratches, protecting the surface integrity of the components, extending their service life, and adapting to components of different specifications, thus improving the versatility and compatibility of the cleaning device. By controlling the clamping force, while ensuring the fixing effect, damage to the components due to excessive clamping is avoided, providing a reliable guarantee for the efficient operation of the horizontal decanter centrifuge, reducing equipment maintenance costs, and improving overall work efficiency.

[0006] Preferably, the length of the control-distance threaded rod is the same as the length of the base, and the surface of the movable clamping seat can be brought into contact with the surface of the fixed clamping seat by the rotation of the control-distance motor. This allows the movable clamping seat to be adjusted within a wide range of the base's length. When dealing with horizontal decanter centrifuges of different lengths, the position of the movable clamping seat can be flexibly controlled by the control-distance motor to ensure precise engagement with the fixed clamping seat, achieving effective clamping and fixing of centrifuges of different specifications. This adaptability mechanism avoids the need to replace the cleaning device due to differences in centrifuge length, improving the applicability and versatility of the cleaning device, and providing an efficient and convenient solution for the automated cleaning of different models of horizontal decanter centrifuges.

[0007] Preferably, the length of the cleaning threaded rod and the length of the cleaning slide rod are the same and symmetrically distributed on both sides of the base, and the interior of the cleaning slide rod seat and the surface of the cleaning slide rod are slidably connected. This provides a stable support structure for the smooth movement of the cleaning slide rod seat. The cleaning slide rod seat slides along the cleaning slide rod, and under the drive of the cleaning threaded rod, it can achieve precise and efficient lateral displacement, ensuring uniform force distribution during movement. This effectively reduces swaying or displacement caused by uneven force distribution, ensuring the stability and reliability of the cleaning operation. For any size horizontal screw centrifuge, the cleaning slide rod seat, through the synergistic action of the cleaning threaded rod and the cleaning slide rod, can cover the entire cleaning area, ensuring comprehensive cleaning and greatly improving cleaning efficiency and effect, meeting the deep cleaning needs under different working conditions.

[0008] Preferably, a telescopic rod seat is fixedly mounted on the surface of the movable plate, a cleaning telescopic rod is fixedly mounted on the surface of the telescopic rod seat, a cleaning seat is fixedly mounted on the output end of the cleaning telescopic rod, a spring groove is formed on the bottom surface of the cleaning seat, a spring is fixedly mounted on the surface of the spring groove, a pressure plate is fixedly mounted on the other end of the spring, and a cleaning brush is fixedly mounted on the surface of the pressure plate. This design provides the cleaning seat with flexible lateral adjustment capabilities, allowing for precise adjustment of the cleaning brush position according to the structural characteristics and cleaning needs of different parts of the decanter centrifuge. This ensures that the cleaning brush can closely conform to complex curved surfaces, gaps, and other areas, achieving all-around cleaning. The design of the spring and pressure plate gives the cleaning brush a pressure adjustment function. When the cleaning brush contacts the component surface, the spring can automatically adjust the pressure applied by the pressure plate and the cleaning brush according to the undulations of the component surface. This ensures that the cleaning brush makes full contact with the component surface to effectively remove dirt, while avoiding damage to the component surface due to excessive pressure. This improves the cleaning effect while protecting the components of the decanter centrifuge, enabling the cleaning device to complete the cleaning task stably and efficiently even under complex operating conditions.

[0009] Preferably, the spring grooves are three in number and evenly distributed on the bottom surface of the cleaning seat, and the side of the pressure plate can be slidably connected between the springs and the inner side of the cleaning seat. Here, during the cleaning process, it ensures that the cleaning brush is subjected to uniform force, avoiding uneven cleaning results caused by excessive or insufficient local pressure. When the cleaning brush contacts the surface of the horizontal screw centrifuge component, the three springs can simultaneously adjust the position and pressure of the pressure plate according to the contour changes of the component surface, ensuring that the cleaning brush always adheres to the component surface with appropriate force. Whether facing a flat area or a complex, uneven structure, it can maintain stable cleaning pressure, effectively improving the consistency and thoroughness of cleaning, while reducing unnecessary wear and tear on the cleaning brush and components caused by uneven pressure, further enhancing the reliability and durability of the cleaning device.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a clamping mechanism, a distance-controlling threaded rod, a cleaning threaded rod, and a cleaning slide bar, the clamping mechanism drives the clamping arm through the clamping motor and the threaded rod, and, in conjunction with the rubber groove and rubber pad, firmly fixes centrifuge components of different specifications. The distance-controlling threaded rod drives the movable clamping seat to cooperate with the fixed clamping seat, achieving precise adaptation to centrifuges of different lengths. The cleaning threaded rod and the cleaning slide bar are symmetrically distributed, and the cleaning slide bar seat can move laterally along the base under the cooperation of the two, achieving full coverage of the cleaning area. The telescopic rod on the cleaning slide bar seat and the cleaning components are closely attached to the surface of the components. All the structures cooperate with each other to achieve all-round and efficient automated cleaning of the centrifuge, improving cleaning efficiency and quality.

[0012] 2. In this utility model, by setting up a cleaning telescopic rod, a cleaning seat, a spring, a pressure plate, and a cleaning brush, the cleaning telescopic rod can be adapted to centrifuge parts of different shapes and specifications, and accurately positioned to the parts that need cleaning, by utilizing the synergistic effect of these structures. When the cleaning brush contacts the surface of the part, the spring will adjust the pressure applied to the cleaning brush by the pressure plate according to the surface undulations, ensuring that the cleaning brush always adheres to the part with the best force, which can thoroughly remove stubborn stains without damaging the surface of the part. Whether it is a smooth outer shell or a complex internal structure, the cleaning brush can achieve high-quality cleaning without dead angles with the cooperation of these structures, which greatly improves the cleaning efficiency and effect, and also extends the service life of the cleaning brush and centrifuge parts.

Protecting the surface integrity of components and extending their service life, this system is adaptable to components of different specifications, improving the versatility and compatibility of the cleaning device. By controlling the clamping force, it ensures a secure hold while preventing damage to components due to excessive clamping, providing a reliable guarantee for the efficient operation of the horizontal screw centrifuge, reducing equipment maintenance costs, and improving overall work efficiency.

[0024] Example 2

[0025] Please see Figure 5A telescopic rod seat 22 is fixedly installed on the surface of the movable plate 20. This seat is used to install the cleaning telescopic rod 23, providing support and a mounting base for the cleaning telescopic rod 23, ensuring stable operation.

When the cleaning brush 28 contacts the component surface, the spring 26 can automatically adjust the pressure plate 27 and the cleaning brush 28 according to the undulations of the component surface. The applied pressure ensures that the cleaning brush 28 makes full contact with the component surface to effectively remove dirt, while avoiding damage to the component surface due to excessive pressure. This improves the cleaning effect while protecting the components of the horizontal screw centrifuge, allowing the cleaning device to complete cleaning tasks stably and efficiently even under complex operating conditions.
