Description

Technical Field

[0001] This utility model relates to the field of large-space filter technology, and in particular to an automatic replacement device for large-space filters. Background Technology

[0002] Large-space side-intake air handling units are ventilation devices specifically designed for large spaces. They effectively improve air circulation and ventilation efficiency by introducing air from the side. They typically feature a high-efficiency filtration system that removes dust and impurities from the air, maintaining indoor air quality. These units are suitable for large spaces such as industrial plants, warehouses, and stadiums. They offer flexible installation options and low operating costs, adapting to various environmental conditions and ensuring uniform and comfortable airflow.

[0003] However, existing large-space side-intake air handling units are usually installed at a height of more than 6 meters above the ground. As the equipment operates, a large amount of dust accumulates on the filter screen, causing the fan to run idle and damaging the equipment, affecting the operating performance. Cleaning the filter screen requires high-altitude work equipment and professional personnel, which is costly and inefficient. Often, the last unit is cleaned and the earliest unit needs to be cleaned again. Although using an electrically driven automatic cleaning system can reduce the manual burden, the limitations of the filter screen material will cause it to wear during use, and the air volume after cleaning will also be affected. Ultimately, manual climbing is still required to replace the filter screen.

[0004] Therefore, those skilled in the art have provided an automatic filter replacement device for large spaces to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic filter replacement device for large spaces. This device can quickly replace the filter using a simple roller rotation, reducing manual cleaning time and labor intensity, as well as reliance on high-altitude work equipment and professionals, thus lowering safety hazards associated with working at heights. Furthermore, the automated design reduces labor costs and equipment maintenance costs, thereby lowering the overall operating cost of the system. The device does not require a complete shutdown during filter replacement, ensuring continuous operation, air circulation, and normal equipment function.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic filter replacement device for large spaces includes a housing. Filtering mechanisms are provided on the upper ends of the outer walls of all four sides of the housing. Each filtering mechanism includes an active box. An active receiving roller is rotatably connected to the center of the bottom surface of the active box. Guide strips are fixedly connected to the upper and lower parts of the rear end of one side of the active box's outer wall. A driven box is fixedly connected to the outer wall of the guide strip on the side away from the active box. A driven fixing shaft is rotatably connected to the center of the bottom surface of the driven box. A driven filter roller is fixedly connected to the middle of the outer wall of the driven fixing shaft. A filter screen is provided on the outer wall of the driven filter roller.

[0008] Through the above technical solution, the automatic filter replacement device for large spaces has a simple structure, which allows users to replace the filter relatively quickly after it is used up. The entire replacement process is simpler and cleaner, reducing the spread of dust and pollutants and improving environmental quality.

[0009] Furthermore, a differential pressure sensor is fixedly connected to one side of the middle of the front outer wall of the housing;

[0010] The above technical solution allows for the detection of the pressure difference between the inside and outside of the chamber.

[0011] Furthermore, a control box is fixedly connected to the middle of the front outer wall of the housing, and a power input switch is fixedly connected to one side of the rear inner wall of the control box.

[0012] The above technical solution enables users to supply power to the filter mechanism via a power switch.

[0013] Furthermore, a control motherboard is fixedly connected to the middle of the inner wall at the rear end of the control box;

[0014] The above technical solution enables the filtration mechanism to be controlled by the motherboard for automatic operation.

[0015] Furthermore, the active boxes are respectively fixedly connected to the outer walls around the box body;

[0016] The above technical solution enables the filtration mechanism to filter the air vents around the housing.

[0017] Furthermore, a constant-speed motor is fixedly connected to the middle of the upper surface of the active box, and the output end of the constant-speed motor is fixedly connected to the active collection roller;

[0018] The above technical solution enables the constant speed motor to control the active collection roller to collect and store the filter screen.

[0019] Furthermore, a filter guide groove is provided in the middle of the outer wall of both the driven box and the active box near the guide bar.

[0020] The above technical solution enables the filter screen to move more accurately from the driven box to the active box.

[0021] This utility model has the following beneficial effects:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-5 One embodiment provided by this utility model:

[0035] An automatic filter replacement device for a large space includes a housing 1. Filtering mechanisms 2 are provided on the upper ends of the outer walls of the housing 1. Each filtering mechanism 2 includes an active box 201. An active receiving roller 203 is rotatably connected to the center of the bottom surface of the active box 201. Guide strips 204 are fixedly connected to the upper and lower parts of the rear end of one side of the outer wall of the active box 201. A driven box 205 is fixedly connected to the outer wall of the guide strips 204 away from the active box 201. A driven fixed shaft 207 is rotatably connected to the center of the bottom surface of the driven box 205. A driven filter roller 208 is fixedly connected to the middle of the outer wall of the driven fixed shaft 207. A filter 209 is provided on the outer wall of the driven filter roller 208.

[0036] This device can quickly replace the filter 209 by simply rotating a roller, reducing the time and labor intensity of manual cleaning, as well as reducing reliance on high-altitude work equipment and professionals, thus reducing safety hazards caused by high-altitude work. The automated design can reduce labor costs and equipment maintenance costs, thereby reducing the overall operating cost of the system. The filter 209 does not need to be completely stopped when it is replaced, which can keep the equipment running continuously, ensuring air circulation and normal operation of the equipment.

[0037] A differential pressure sensor 3 is fixedly connected to one side of the middle of the front outer wall of the housing 1 to detect the pressure difference between the inside and outside of the housing 1. A control box 4 is fixedly connected to the middle of the front outer wall of the housing 1. A power input switch 5 is fixedly connected to one side of the rear inner wall of the control box 4, allowing the user to supply power to the filter mechanism 2 via the power input switch 5. A control main board 6 is fixedly connected to the middle of the rear inner wall of the control box 4, allowing the filter mechanism 2 to be operated automatically by the control main board 6. Active boxes 201 are fixedly connected to the outer walls of the housing 1 on all four sides, thereby... The filter mechanism 2 can filter the air vents around the box 1. A constant speed motor 202 is fixedly connected to the middle of the upper surface of the active box 201. The output end of the constant speed motor 202 is fixedly connected to the active collection roller 203, so that the constant speed motor 202 can control the active collection roller 203 to collect and store the filter screen 209. The driven box 205 and the active box 201 are both provided with filter screen guide grooves 206 in the middle of the outer wall of the side near the guide strip 204, so that the filter screen 209 can move more accurately from the driven box 205 to the active box 201.

[0038] Working principle: First, a new filter screen 209 is installed on the driven filter screen roller 208. Then, one end of the filter screen 209 is guided and fixed to the active collection roller 203 through the filter screen guide groove 206 and guide strip 204. The differential pressure sensor 3 installed on the outside of the housing 1 is used to detect the clogging of the filter screen 209. If there is a change in internal and external pressure, the information is transmitted to the control main board 6 connected to it. The control main board 6 makes a judgment on whether to replace it. When replacing, the constant speed motor 202 is started, which rotates the active collection roller 203 and the driven filter screen roller 208 synchronously by a fixed angle, thereby removing the new part of the filter screen 209 and collecting the used filter screen 209. After the constant speed motor 202 is started a preset number of times and the filter screen 209 is completely used, the differential pressure sensor 3 is started again, which will cause the control main board 6 to send a signal to the connected equipment, so that the user can replace the filter screen 209 and restart the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
