Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a bottom cleaning device for tanks. Background Technology

[0002] In wastewater treatment at chemical production plants, microfiltration devices are crucial water treatment equipment, and their operational efficiency directly impacts the overall effectiveness of the wastewater treatment system. However, during actual operation, the sludge produced by the microfiltration device gradually accumulates at the bottom of the sludge tank, forming a thick layer. Over time, this accumulated sludge not only occupies the effective volume of the sludge tank, reducing the treatment capacity of the microfiltration device, but may also clog the microfiltration membrane, affecting the quality of the effluent. Traditional methods for cleaning microfiltration sludge tanks mainly rely on manual operation, which is labor-intensive, incomplete, and inefficient. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a bottom cleaning device for tanks, which solves the technical problem of traditional manual cleaning of microfiltration tanks.

[0004] To achieve the above and other related objectives, this utility model provides a bottom slag cleaner, comprising:

[0008] The advantages of the above technical solution are that by driving the scraper plate to move at the bottom of the tank through the drive mechanism, the slag deposited at the bottom of the tank can be automatically scraped and pushed to the collection ditch. This changes the traditional operation method of manually cleaning the slag at the bottom of the slag tank one by one, realizes the automation of the slag cleaning process, reduces the reliance on manual operation, and sets up a collection ditch parallel to the scraper plate at the edge of the tank. The scraper plate pushes the slag to the collection ditch under the action of the drive mechanism, providing a specific location for the centralized collection of slag, which is convenient for the subsequent unified treatment of slag.

[0009] Optionally, the drive mechanism includes a mounting beam, two slide rails and a motor.

[0033] Please see Figures 1 to 2 As shown, this utility model provides a bottom slag cleaner, comprising:

[0034] The tank 1 is equipped with a drive mechanism.

[0035] The scraper 2 is mounted on the trough 1 via the driving mechanism, and the lower edge of the scraper 2 slides in contact with the bottom of the trough 1.

[0036] A collection groove is provided at the bottom of the tank 1. The collection groove is located at the edge of the tank 1 and is parallel to the scraper 2. The driving mechanism is used to drive the scraper 2 to move closer to or away from the collection groove.

[0037] It should also be noted that by driving the scraper plate to move at the bottom of the tank through the drive mechanism, the slag deposited at the bottom of the tank can be automatically scraped and pushed to the collection ditch. This changes the traditional operation method of manually cleaning the slag at the bottom of the slag tank cell by cell, realizes the automation of the slag cleaning process, and reduces the reliance on manual operation. A collection ditch is set at the edge of the tank parallel to the scraper plate. Under the action of the drive mechanism, the scraper plate pushes the slag to the collection ditch, providing a specific location for the centralized collection of slag. This facilitates the unified treatment of the slag in the subsequent process. For example, the slag in the collection ditch can be transferred to a plate and basket filter press for filter pressing through other devices such as a slag pump, which reduces labor intensity and improves slag cleaning efficiency.

[0038] Meanwhile, the collection ditch is equipped with a valve for sealing the collection ditch.

[0039] Furthermore, during production setup, the height of the tank wall of the tank 1 can be adjusted according to the actual production situation. At the same time, the height of the scraper 2 can also be adjusted to promptly clean the slag generated by the microfiltration device.

[0040] In one embodiment, the scraper 2 can also be driven by a rack and pinion mechanism to move along the groove 1.

[0041] For example, the drive mechanism includes a mounting beam 101, two slide rails 102 and a motor. The slide rails 102 are disposed on the outside of the groove 1, and the mounting beam 101 is horizontally disposed above the groove 1. The two ends of the mounting beam 101 are respectively slidably disposed in the corresponding slide rails 102.

[0042] It should also be noted that the mounting beam 101 serves as the mounting base for the scraper blade 2, positioned above the trough 1. Through its sliding design at both ends within the slide rails, a stable moving frame is constructed for the scraper blade. This allows the scraper blade to move smoothly above the trough along the path set by the slide rails under the action of the drive mechanism, thereby effectively cleaning slag from different locations at the bottom of the trough. The motor provides power for the movement of the mounting beam, and through its cooperation with the slide rails, the mounting beam drives the scraper blade to perform linear reciprocating motion above the trough. This motion ensures that the scraper blade maintains a stable trajectory during movement, evenly and effectively pushing the slag from the bottom of the trough towards the collection ditch, improving the slag removal effect.

[0043] For example, the motor is a stepper motor.

[0044] It should also be noted that stepper motors can convert electrical pulse signals into angular or linear displacement. By controlling the number of input pulses, the rotation angle of the motor can be precisely controlled, thereby precisely controlling the movement distance of the scraper driven by the mounting beam. This ensures that the scraper moves at a preset position and distance on the bottom of the trough, accurately pushing the slag towards the collection ditch, achieving precise slag removal. The stepper motor has a positioning function; when it receives a stop pulse signal, it can immediately stop rotating and maintain its current position. During the slag removal process, this characteristic allows the scraper to stop accurately when it reaches the collection ditch or other designated positions, avoiding excessive or insufficient movement of the scraper and ensuring the accuracy and stability of the slag removal operation.

[0045] For example, the side of the scraper 2 is arc-shaped.

[0046] It should also be noted that the bottom of the microfiltration sludge tank is usually not completely flat and may have a certain curvature or irregular shape. The scraper is designed with curved sides to better conform to the contour of the tank bottom, forming a closer contact with the tank bottom surface during movement. This more effectively scrapes up and pushes the sludge adhering to the tank bottom, avoiding sludge residue due to gaps between the scraper and the tank bottom, and improving the thoroughness of sludge removal.

[0047] For example, the bottom of the tank 1 is also provided with a collection well 5, which penetrates the tank 1 and is located in the collection ditch.

[0048] It should also be noted that the collection well 5 is located inside the collection ditch and runs through the trough, providing a centralized collection space for the slag material flowing from the collection ditch. After the scraper pushes the slag material from the bottom of the trough into the collection ditch, the slag material flows into the collection well 5 along the collection ditch, realizing centralized management of the slag material. This facilitates subsequent unified processing of the slag material, such as pumping the slag material in the collection well 5 to a plate and basket filter press for filtration. As a temporary storage point for the slag material, the design of the collection well 5, which runs through the trough, allows the slag material transfer equipment to be easily connected to the collection well 5, directly extracting and transferring the slag material from the collection well 5, simplifying the slag material transfer process and improving transfer efficiency.

[0049] For example, a pusher plate 3 is also slidably provided in the collection groove. The pusher plate 3 is arranged vertically, and the edge of the pusher plate 3 slides in contact with the inner wall of the collection groove.

[0050] It should also be noted that after the scraper pushes the slag from the bottom of the trough to the collection ditch, the pusher plate can slide to further push the slag in the collection ditch, ensuring that the slag can flow smoothly to the collection well 5. Especially when the amount of slag is large or the viscosity is high and the flow is not smooth, the role of the pusher plate is more obvious. It can effectively prevent the slag from accumulating and blocking in the collection ditch, ensure the continuity of slag collection and transportation, improve the thoroughness of slag cleaning, and has a simple structure and low cost.

[0051] For example, the outside of the tank 1 is also provided with a telescopic device 4, the movable end of the telescopic device 4 is connected to the push plate 3, and the telescopic device 4 is used to drive the push plate 3 to move closer to or away from the collection well 5.

[0052] It should also be noted that the telescopic device can precisely control the moving distance and position of the push plate. Through the telescopic movement of the telescopic device, the push plate can be driven to move in the collection ditch according to a predetermined trajectory and distance, thereby accurately pushing the slag in the collection ditch to the collection well 5, and realizing the efficient collection of slag.

[0053] For example, the bottom of the tank 1 is also provided with a plurality of water outlet holes a.

[0054] In one embodiment, water or other cleaning liquid can be injected into the bottom of the tank through the water outlet. The water flow can lubricate and flush, making it easier for the slag adhering to the bottom of the tank to be scraped and pushed by the scraper, reducing the adhesion between the slag and the bottom of the tank, and improving the slag removal effect.

[0055] For example, the tank 1 is a hollow structure, the cavity of the tank 1 is connected to all the water outlet holes a, and a water outlet pipe is also provided on the outer wall of the tank 1, the water outlet pipe is connected to the cavity of the tank 1.

[0056] It should also be noted that the water outlet pipe is connected to the tank cavity. By controlling the valves, pumps, and other equipment at the water outlet pipe, parameters such as water flow and pressure entering the tank cavity can be easily controlled. This eliminates the need to operate each water outlet individually, simplifying the water flow control process and improving operational convenience and efficiency.

[0057] In one embodiment, such as Figure 3 As shown, the bottom cleaning device of this application is used to receive the residue filtered out by the microfiltration device. The microfiltration device can be set above the bottom cleaning device. The microfiltration device is set in the filter tank, and the bottom cleaning device is installed at the bottom of the filter tank and acts as the bottom of the filter tank. At the same time, a guide plate is also provided on the tank wall of the filter tank. The guide plate is inclined and set above the slide rail 102 to prevent the residue from entering the slide rail 102. At the same time, the telescopic device 4 and the motor of the drive mechanism are both waterproof structures. A sealing strip b is also provided at the connection between the bottom cleaning device and the filter tank.

[0058] In summary, the slag remover of this utility model, driven by a drive mechanism, moves a scraper plate along the bottom of the tank, automatically scraping and pushing the slag deposited at the bottom of the tank towards the collection ditch 5. This changes the traditional method of manually cleaning the slag at the bottom of the tank cell by cell, automating the slag removal process and reducing reliance on manual operation. A collection ditch parallel to the scraper plate 2 is set at the edge of the tank. Under the action of the drive mechanism, the scraper plate 2 pushes the slag to the collection ditch, providing a specific location for the centralized collection of slag, facilitating subsequent unified processing of the slag.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
