[0002] In many industrial fields, moisture in the air affects product quality and production efficiency. Using an air purification device can effectively remove moisture from the air, thereby ensuring the quality and production efficiency of indoor products. For example, in the chemical industry, chemical reactions usually require precise temperature and humidity conditions, and moisture in the air affects the speed of the reaction and the quality of the product. By using an air purification device, moisture in the air can be removed to ensure the quality and efficiency of the reaction. In addition, air purification devices can also be used for air purification. Moisture in the air not only affects product quality and production efficiency, but also affects the life of mechanical equipment. In the electronics manufacturing industry, moisture may cause corrosion and damage to electronic components. Using an air purification device can remove moisture from the air and ensure the life of mechanical equipment and electronic components.

[0003] The air purification device under the existing technology pre-filters the outside air by setting a filter inside. As the device is used for a longer time, a large number of dust particles adhere to the surface of the filter. To ensure the normal filtering efficiency of the filter, the staff needs to remove the internal filter and further install a new filter. This operation method is relatively cumbersome and reduces the working efficiency of the air purification and drying device. Utility Model Content

[0026] Example:

[0027] See also Figure 1-Figure 3 As shown, the utility model is an air purification and drying device, comprising

[0028] The shell 1 has an air inlet 2 and an air outlet 3 at both ends thereof;

[0029] A negative pressure component is disposed inside the housing 1 and close to a side of the air outlet 3;

[0030] A filter plate 4, the filter plate 4 is fixedly arranged on the inner wall of the housing 1, a molecular sieve plate 5 is arranged on one side of the filter plate 4, a switch 6 is arranged on one side of the molecular sieve plate 5, and the molecular sieve plate 5 and the switch 6 are both fixedly installed inside the housing 1;

[0032] A cleaning component is arranged on one side of the filter plate 4;

[0033] The collecting component is arranged below the cleaning component and is used for collecting and processing the dust scraped off the surface of the filter plate 4.

[0034] The negative pressure component includes a base 7 and a negative pressure fan 8 . The base 7 is fixedly disposed on the inner bottom wall of the shell 1 , and the negative pressure fan 8 is fixedly disposed on the base 7 .

[0035] The pressure difference monitoring component includes a first pressure sensor 9 and a second pressure sensor 10 , which are respectively arranged on both sides of the filter plate 4 , and one end of the first pressure sensor 9 and the second pressure sensor 10 are fixedly connected to the inner wall of the shell 1 .

[0036] Specifically, when the negative pressure fan 8 is started, the outside air enters the housing 1 through the air inlet 2, the air is firstly dusted by the filter plate 4, then the air is preliminarily dried by the molecular sieve plate 5, and then the gas is heated by the switch 6 to facilitate further drying of the air;

[0037] By arranging the first pressure sensor 9 and the second pressure sensor 10 on both sides of the filter plate 4, it is convenient to monitor the pressure value of the gas on both sides of the filter plate 4 in real time. Furthermore, the blocking degree of the mesh holes of the filter plate 4 is judged by the pressure difference, so as to facilitate the subsequent automatic cleaning of the dust on the surface of the filter plate 4.

[0038] A controller 11 electrically connected to the first pressure sensor 9 and the second pressure sensor 10 is fixedly connected to the bottom wall of the housing 1 .
