Description

Technical Field

[0001] This utility model relates to the technical field of textile workshop rotating drum equipment, and in particular to a self-cleaning and anti-clogging structure for a textile workshop rotating drum filter. Background Technology

[0002] In the production process of textile workshops, the rotary drum is a cylindrical device that plays a key processing role. Its core function is to clean, fluff, and shape the fabric through high-speed rotation. It is usually made of metal mesh or perforated steel plate into a cylindrical body with transmission devices connected to both ends. During operation, it is driven by a motor to rotate, and the speed can be adjusted according to the fabric material and process requirements. For fabrics that have just been dyed, printed, or preliminarily finished, the rotary drum can remove residual dye, auxiliaries, and moisture through centrifugal force. At the same time, the airflow generated by the rotation keeps the gaps between the fibers and prevents the fabric from becoming compacted or wrinkled due to compression. Therefore, a self-cleaning and anti-clogging structure for the rotary drum filter in textile workshops is needed.

[0003] The existing self-cleaning and anti-clogging structure of the rotary drum filter in the textile workshop cannot adhere tightly to the inner wall during cleaning, which easily leaves impurities and causes blockage. The wastewater generated during cleaning is not equipped with a filtration and recycling device and cannot be reused, resulting in water waste. This not only affects the continuous and stable operation of the equipment, but also increases the cost of production water.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN207838556U for a rotary air filter for textile air conditioning. The patent describes a rotary air filter comprising a horizontally placed hollow cylindrical rotary cage and a central shaft fixed axially through the center of the cage. The two ends of the central shaft located outside the cage are connected to vertical support columns via bearing seats, supporting the cage off the ground. The side walls of the cage are screen structures. The key feature is that one end face of the cage is a screen structure, while the other end face is open, making one end face the air inlet and the other the air outlet. The screen structure consists of filter mesh covered with filter material. A pulley is located at the open end of the central shaft, connected to a motor drive. This invention changes one end face of the rotary cage from a sealed surface to a screen structure, creating a ventilation surface. This not only effectively increases the filtration area of ​​the equipment, solving the problem of insufficient filtration area when space is limited, but also reduces the pressure difference inside and outside the cage, reducing ventilation power consumption and operating costs, resulting in excellent performance. However, while it increases the filtration area, it cannot be cleaned, leading to internal blockage with prolonged use. Utility Model Content

[0005] The purpose of this utility model is to provide a self-cleaning and anti-clogging structure for a rotary drum filter in a textile workshop, so as to solve the problems mentioned in the background art. The existing self-cleaning and anti-clogging structure of the rotary drum filter in the textile workshop cannot adhere tightly to the inner wall during cleaning, and is prone to leaving impurities that cause blockage. The wastewater generated during cleaning is not equipped with a filtration and recycling device and cannot be reused, resulting in water waste. This not only affects the continuous and stable operation of the equipment, but also increases the production water consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning and anti-clogging structure for a textile workshop rotary drum filter, comprising a base, a rotary drum disposed above the base, a second drive motor disposed on one side surface of the rotary drum, a connecting rod connected to the output end of the second drive motor, a connecting column embedded in the inner surface of the connecting rod, a spring fixedly connected to the inner surface of the connecting column, a support column fixedly connected to one end surface of the spring, a support rod fixedly connected to the upper surface of the support column, a water tank mounted on the upper surface of the base, a water supply pipe connected to the upper surface of the water tank, a water pump connected to one side surface of the water supply pipe, a water outlet pipe connected to one side surface of the water pump, a first solenoid valve sleeved on the outer surface of the water outlet pipe, a suction pipe disposed on one side surface of the water outlet pipe, a second solenoid valve sleeved on the outer surface of the suction pipe, a cleaning tank sleeved on the outer surface of the suction pipe, and a sludge pump connected to one end surface of the suction pipe.

[0007] Preferably, a first gear is fixedly connected to the outer surface of the rotating cage, a second gear is meshed with the outer surface of the first gear, a first drive motor is connected to one side surface of the second gear, a pulley is provided on the outer surface of the rotating cage, and a placement rack is installed on the upper surface of the base.

[0008] Preferably, a sealing ring is embedded in the inner surface of the connecting column, and the outer wall of the sealing ring is fitted with the supporting column.

[0009] Preferably, a cleaning brush is attached to the upper surface of the support rod.

[0010] Preferably, the inner surface of the cleaning tank is provided with a filter screen, and the outer surface of the cleaning tank is threadedly connected with a connecting cover.

[0011] Preferably, a sludge pump is fixedly installed on the upper surface of the base, and a return pipe is connected to one side surface of the sludge pump.

[0012] Preferably, a ball bearing is connected through one side surface of the rotating cage, a ball bearing is connected to the inner surface of the conveying pipe, and the water outlet pipe and the pumping pipe are both connected to the conveying pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The self-cleaning and anti-clogging structure of the textile workshop rotary drum filter allows water from the tank to enter the drum through the water supply and outlet pipes after the water pump is started. Once the required amount is reached, the first solenoid valve is closed, and the second drive motor drives the connecting rod to rotate. The spring pushes the support column upward, causing the support rod to press the cleaning brush against the inner wall of the filter for cleaning, ensuring no dead corners are left. The sealing ring prevents water from entering the connecting column and causing the spring to rust, extending the service life of the components and ensuring the stable operation of the cleaning structure. After cleaning, the second solenoid valve is opened, and the sewage pump draws the sewage from the drum to the cleaning tank through the suction pipe. Impurities are trapped by the filter screen, and the filtered water is returned to the water tank for reuse through the return pipe, reducing water waste and avoiding pollution caused by direct sewage discharge. When the filter screen is full, the connecting cover can be opened to remove it for cleaning and reinstallation. The operation is simple. After cleaning, the first drive motor is started, and the drum is rotated through gear transmission to resume use. The entire self-cleaning process is highly automated, reducing manual intervention.

A second solenoid valve 22 is sleeved on the outer surface of the suction pipe 21. A cleaning tank 23 is sleeved on the outer surface of the suction pipe 21. A sludge pump 26 is connected to one end of the suction pipe 21.

[0022] Furthermore, a first gear 3 is fixedly connected to the outer surface of the rotating cage 2, a second gear 4 is meshed with the outer surface of the first gear 3, a first drive motor 5 is connected to one side surface of the second gear 4, a pulley 6 is provided on the outer surface of the rotating cage 2, and a placement rack 7 is installed on the upper surface of the base 1. The second drive motor 8 can be installed through the placement rack 7.

[0023] Furthermore, a sealing ring 12 is embedded in the inner surface of the connecting column 10, and the outer wall of the sealing ring 12 fits against the support column 13. The sealing effect is improved by setting the sealing ring 12.

[0024] Furthermore, a cleaning brush 15 is attached to the upper surface of the support rod 14, which improves the cleaning effect.

[0025] Furthermore, a filter screen 24 is provided on the inner surface of the cleaning tank 23, and a connecting cover 25 is threadedly connected to the outer surface of the cleaning tank 23. The filter screen 24 can be disassembled and cleaned by the connection cover 25.

[0026] Furthermore, a sewage pump 26 is fixedly installed on the upper surface of the base 1, and a return pipe 27 is connected to one side surface of the sewage pump 26. The sewage pump 26 enables the sewage to be pumped out.

[0027] Furthermore, a ball bearing 29 is connected through one side surface of the rotating drum 2, and a ball bearing 29 is connected to the inner surface of the conveying pipe 28. The water outlet pipe 19 and the pumping pipe 21 are both connected to the conveying pipe 28. The use of the ball bearing 29 improves the performance.

[0028] Working principle: First, water pump 18 is started. Then, water pump 18 draws water from water tank 16 through water supply pipe 17. Next, water pump 18 inputs water into outlet pipe 19. Then, the first solenoid valve 20 is opened and the second solenoid valve 22 is closed. Water then enters the transfer pipe 28 through outlet pipe 19 and then into rotating drum 2. When the water supply reaches the specified amount, the first solenoid valve 20 is closed. Then, the second drive motor 8 is started. The output of the second drive motor 8 drives the connecting rod 9 to rotate. During the rotation cleaning, spring 11 pushes the support column 13 to rise. When the support column 13 rises, it squeezes the cleaning brush 15 through the support rod 14 to adhere to the inner wall of the filter for cleaning. At the same time, the sealing ring 12 acts as a waterproof ring to prevent water from entering the connecting column. The spring 11 inside 10 rusts. After the rotating drum 2 is cleaned, the second solenoid valve 22 can be opened, and then the sludge pump 26 can be started. Then the sludge pump 26 drives the conveying pipe 28 through the pumping pipe 21 to pump the sewage in the rotating drum 2 into the cleaning tank 23 for filtration. Then the impurities in the sewage will remain in the filter screen 24. Then the filtered water is pumped back into the sludge pump 26, and then transmitted to the water tank 16 through the return pipe 27 for reuse. When the filter screen 24 is full, the connecting cover 25 can be opened to remove the filter screen 24 for cleaning and reinstallation for reuse. After cleaning is completed, the first drive motor 5 can be started, and the first drive motor 5 drives the second gear 4 to rotate. Then the rotating drum 2 can be rotated through the first gear 3.
