Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment accessories, in particular to a heat-insulating and explosion-proof circulating fan for intelligent ventilation. Background Art

[0002] Grain reserve is a material reserve system established by the state to ensure the food consumption demand of non-agricultural population, adjust the balance of grain supply and demand, stabilize the grain market price, and cope with major natural disasters or other emergencies. A grain reserve depot is a place for storing grain. The general requirements for a grain reserve depot are good heat preservation and moisture retention effects, so that the temperature difference between day and night in the warehouse is not large, and it is as low as possible. Generally, the highest grain temperature does not exceed 30 degrees in summer and autumn.

[0003] In order to achieve good storage effect of grains, ventilation openings and fans are generally arranged on the warehouse. The cold air at the bottom of the warehouse is extracted by the fan and conveyed to the top of the warehouse through internal circulation for self-regulation. However, the cold air contains more moisture, making it heavier and affecting the storage of grains. To solve this problem, a structure for treating more moisture is needed. Therefore, we design a heat-insulating and explosion-proof circulating fan for intelligent ventilation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a heat-insulating and explosion-proof circulating fan for intelligent ventilation is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

An adsorption mechanism is connected to the air inlet of the circulating fan, and the adsorption mechanism is connected with a connecting flange;

[0007] The adsorption mechanism includes an installation box fixed between the air inlet and the connecting flange. Through holes communicating with the air inlet and the connecting flange are opened on the installation box. A plug cover is installed on the top of the installation box. Two rolling rollers located on both sides of the inner wall of the installation box are installed at the bottom of the plug cover. The same water-absorbing filter cloth is wound on the two rolling rollers, and small holes are evenly opened on the water-absorbing filter cloth. A driving mechanism for realizing the rotation of the rolling roller is installed on the plug cover.

[0008] As a further solution of the utility model, the driving mechanism includes a synchronous pulley fixed to the top of the rolling roller. The two synchronous pulleys are connected by a synchronous belt. A driving motor coaxially fixed with one of the synchronous pulleys is fixed on the top of the plug cover, and the inner wall of the other synchronous pulley is rotatably connected.

[0009] As a further solution of the utility model, one end of the water-absorbing filter cloth is bonded to the outer wall of a roller away from the driving motor, and the water-absorbing filter cloth is wound around the outer wall of the roller. The other end of the water-absorbing filter cloth is bonded to the roller coaxial with the driving motor.

[0010] As a further solution of the utility model, rubber rings are fixed at both ends of the inner wall of the installation box, and the water-absorbing filter cloth passes through the space between the two rubber rings to form a fit.

[0011] As a further solution of the utility model, aligned jacks are provided on both the plug cover and the rubber ring near the air inlet, and a humidity sensor is inserted into the jacks.

[0012] As a further solution of the utility model, a battery and a control box are installed on the top of the plug cover, and a controller is installed in the control box. The controller is electrically connected to the humidity sensor and the driving motor. The humidity sensor is used to detect the air passing through the water-absorbing filter cloth. If the humidity is still high, it is considered that the water-absorbing filter cloth is overloaded. The controller automatically controls the driving motor to work, pulls out a new water-absorbing filter cloth for adsorption, and realizes intelligent detection.

The limiting frame, T-shaped installation frame and pressing roller are installed on the inner wall of the installation box to press the water-absorbing filter cloth to prevent the water-absorbing filter cloth from moving and rubbing against the inner wall of the installation box.

[0014] As a further solution of the utility model, an explosion-proof housing is detachably installed on the outer wall of the circulation fan, and the motor of the circulation fan is located in the explosion-proof housing, which plays a protective role.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model adopts the circulating fan, explosion-proof shell, air inlet, connecting flange and adsorption mechanism, so when wind enters the circulating fan, it will first pass through the adsorption mechanism and dry the moisture in the air through the water-absorbing filter cloth.

[0030] In this embodiment, one end of the water-absorbing filter cloth 8 is bonded to the outer wall of a roller 7 away from the driving motor 9, and the water-absorbing filter cloth 8 is wound around the outer wall of the roller 7. The other end of the water-absorbing filter cloth 8 is bonded to the roller 7 coaxial with the driving motor 9.
