Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an automatic winding device for W-shaped filter cloth. Background Technology

[0002] Traditional air purifiers use pre-filters (medium-efficiency and high-efficiency filters) in various types, including bag filters, pleated plate filters, pleated cylindrical filters, and roller shutter filters. After a period of operation, traditional bag, pleated plate, and pleated cylindrical filters accumulate a large amount of dust particles and other pollutants on their surfaces. Due to their small dust holding capacity, these filters must be replaced regularly to ensure filtration efficiency. However, frequent filter replacements increase maintenance costs. Traditional roller shutter filters (flat rotating type, W-shaped rotating type) rely primarily on the tensile strength of the filter cloth to withstand wind resistance, placing stringent requirements on the tensile strength of the filter cloth material. Therefore, there is an urgent need to design a W-shaped automatic filter cloth rotating device to achieve automatic cloth replacement, increase the one-time dust holding capacity, extend the filter's service life and replacement cycle, and reduce the stringent requirements on the tensile strength of the filter cloth. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a W-type filter cloth automatic winding device to realize automatic cloth replacement, ensure the effective filtration area of ​​the filter cloth in real time, and ensure filtration efficiency. At the same time, a mesh plate is set on the leeward side of the filter cloth to prevent the filter cloth from being deformed by pressure and affecting the filtration effect, and to protect the tensile strength of the filter cloth to withstand wind resistance. It is suitable for use with various air purification machines and equipment to adsorb and collect dust particles.

[0004] The purpose of this utility model is achieved as follows:

[0005] An automatic winding device for W-shaped filter cloth includes a filter frame, guide rollers, a new cloth roller, an electric roller, and a take-up roller. The filter frame has a vertically penetrating air duct. Guide rollers are rotatably mounted inside the filter frame, while the new cloth roller and take-up roller are rotatably mounted outside the filter frame. The take-up roller is driven to rotate by the electric roller. One end of the filter cloth is wound onto the new cloth roller, and the other end is wound onto the take-up roller after being guided by multiple W-shaped guide rollers within the filter frame. A mesh plate is provided on the leeward side of each section of filter cloth, with the mesh plate inclined in the same direction as the corresponding filter cloth section. The mesh plate is fixed to the filter frame by a V-shaped frame, and both ends of the mesh plate are fixed to the V-shaped frame by bolts.

[0006] Preferably, the guide rollers are provided in two rows, and the two rows of guide rollers are arranged in a W-shape, alternating vertically.

[0007] Preferably, when the air purification machine or equipment is equipped with a differential pressure sensor, the high-pressure end and the low-pressure end of the differential pressure sensor are respectively connected to the high-pressure air inlet side and the low-pressure air outlet side, and the differential pressure sensor and the electric roller are both electrically connected to the controller.

[0008] Preferably, the new fabric roller and the electric roller are symmetrically arranged at the bottom of the filter frame body through a connecting plate. The electric roller is fixedly fitted with a take-up roller, and transmission connecting sleeves are fixed at both ends of the electric roller. The take-up roller is connected to the transmission connecting sleeve by bolts.

[0009] Preferably, the guide rollers near the inlet and outlet ends of the filter cloth adopt a double roller structure, and the filter cloth enters and exits the filter frame through the paired double rollers.

[0010] The beneficial effects of this utility model are:

[0011] It can automatically replace the filter cloth. When the air enters the filter cloth from the front, there is a slight pressure difference that sticks the filter cloth to the mesh plate, preventing adjacent filter cloths from sticking together and affecting the filtration effect, preventing the filter cloth from being deformed by pressure and affecting the filtration effect, and protecting the tensile strength of the filter cloth to withstand wind resistance.

[0012] When the filter cloth traps particulate pollutants, causing the air resistance to reach the set differential pressure value, the differential pressure sensor feeds back the differential pressure signal to the controller. The controller drives the electric roller and the cloth take-up roller on it to rotate synchronously to automatically replace the contaminated filter cloth. When the number of new cloth rolls designed to meet a certain value (from tens of meters to thousands of meters), it can automatically replace the filter cloth dozens to hundreds or even thousands of times. Once a new filter cloth is filled, it can be used for a long time. The replacement cycle is long, saving operating costs. It is suitable for use with a variety of air purification machines and equipment, and is suitable for the installation and use of primary, medium and high efficiency filter cloths.

[0019] See Figure 1-5 This utility model relates to an automatic winding device for W-shaped filter cloth, including a filter frame 1, a guide roller 2, a new cloth roller 3, an electric roller 4, and a take-up roller 5. The filter frame 1 has a vertically penetrating air duct inside. The guide roller 2 is rotatably mounted inside the filter frame 1. The new cloth roller 3 and the take-up roller 5 are rotatably mounted outside the filter frame 1. The take-up roller 5 is driven to rotate by the electric roller 4. The new cloth roller 3 and the electric roller 4 are symmetrically arranged at the bottom outside the filter frame 1 through a connecting plate 6. The take-up roller 5 is fixedly sleeved on the outside of the electric roller 4. Transmission connecting sleeves 7 are fixed at both ends of the electric roller 4. The take-up roller 5 is connected to the transmission connecting sleeves 7 by bolts, thereby fixing the electric roller 4 and the take-up roller 5.

[0020] One end of the filter cloth 8 is wound around the new cloth roller 3, and the other end is wound around the take-up roller 5 after passing through multiple guide rollers 2W-shaped guide cloth inside the filter frame 1.

[0021] The guide rollers 2 are arranged in two rows, and the two rows of guide rollers 2 are arranged in a W-shape and staggered, which makes it easier for the filter cloth 8 to form a W-shaped structure in the filter frame 1, thereby increasing the spread area of ​​the filter cloth in the filter frame and enhancing the filtration effect.

[0022] To prevent adjacent fabric surfaces from sticking together within the filter frame 1 and reducing the effective filtration area, a mesh plate 9 is installed on the leeward side of each filter fabric section. The mesh plate 9 is inclined in the same direction as the corresponding filter fabric section. The mesh plate 9 is fixed inside the filter frame 1 by a V-shaped frame 10, and both ends of the mesh plate 9 are fixed to the V-shaped frame 10 by bolts. When air enters the filter fabric from the front, a slight pressure difference causes the filter fabric to stick to the mesh plate 9 on the leeward side, preventing adjacent fabric surfaces from sticking together.

[0023] When this device is used in conjunction with air purification machines and equipment, it is equipped with a differential pressure sensor (not shown in the figure). The differential pressure sensor and the electric roller 4 are electrically connected to the controller. When the air resistance caused by the filter cloth trapping particulate pollutants reaches the set differential pressure value, the differential pressure sensor feeds back the differential pressure signal to the controller. The controller drives the electric roller 4 and the cloth taking-up roller 5 on it to rotate synchronously to automatically replace the contaminated filter cloth. When the number of new cloth rolls designed to meet a certain value (from tens of meters to thousands of meters), it can automatically replace the filter cloth dozens to hundreds or even thousands of times. Once a new filter cloth is filled, it can be used for a long time, reducing the replacement frequency and saving operating costs.
