The production automation level of the existing large-scale iron and steel enterprises is higher and higher, an electric system mostly adopts a combined operation scheme, and the operation control, protection, monitoring, fault information management and the like of a production line are carried out in a combined electric room. The large-scale combined electric room usually has the characteristics of large building area, compact equipment arrangement and large equipment heating value, so that the temperature control form is usually selected as an all-air central air conditioning system. The central air conditioning system is an air conditioner which is used for controlling different units by one or more cold and heat source systems through a mode that air ducts are connected with a plurality of tail ends through air ducts so as to achieve the purpose of indoor air conditioning. The air quantity of each air port is inversely proportional to the resistance of the air pipe, but because the working conditions of steel mills are different, the air quantity in the air duct of the central air-conditioning system is mainly adjusted by the operation unit, and the air quantity of the air outlet in the combined electric room is passively fluctuated along with the air quantity of the central air-conditioning system, so that the problem in the prior art is solved by installing an air valve in the air pipe. The air valve principle is that blades are driven to rotate through a manual or electric connecting rod to adjust the area of an air outlet, however, the adjustment is manual control, and the air valve with the automatic air volume setting and automatic air volume adjusting capacity is required to be set in an electronic programming mode, the price is 1500-2800 yuan, the cost is high, and the air valve cannot be maintained automatically. In addition, the working condition characteristics of the steel plant are high temperature and dust, and the concentration of various non-air component particles contained in the air is high occasionally, so that the problem of dust deposition in a common workshop cannot occur, but for a production line combined electric room with a large amount of electrical equipment, the particle deposition has certain corrosivity on working equipment and units, and therefore, the dust amount of an indoor air outlet of the full-air conditioning system of the steel production line combined electric room is necessary to be reduced.

Detailed Description

The invention is further described with reference to the drawings and the detailed description. For convenience of description, the direction toward the inside of the room is set as the inside, and the direction toward the outside of the room is set as the outside.

As shown in fig. 1, the present invention includes a housing 7, a filter screen 1, and an electrostatic plate 16.

The shell 7 is arranged in an L-shaped turn in the central air-conditioning air duct 17, and the shell 7 is provided with a front opening and a rear opening which respectively face the indoor space and the outdoor space. The shell 7 is internally provided with a motor 2 and a lead screw 3. The output shaft of the motor 2 is connected with the inner end of the screw rod 3, wherein the outer end part of the screw rod 3 is of a smooth cylindrical structure without threads.

The shell 7 is also internally provided with a fan 4, a connecting rod 13 and a circular ring 5. The fan 4 comprises a cylindrical structure 14 and blades fixed on the cylindrical structure 14, a thread structure matched with the lead screw 3 is arranged on the surface of a central hole of the cylindrical structure 14, and the lead screw 3 penetrates through the middle of the central hole of the cylindrical structure 14. The rotation directions of the blades and the threads meet the requirement that when the fan 4 is blown to rotate by wind power indoors outdoors, the fan 4 moves inwards through the action of the threads. The outer side end of the cylindrical structure 14 is provided with teeth 6, the outer end of the screw rod 3 is also fixedly provided with teeth 8 which can be mutually embedded with the screw rod, the two groups of

teeth

6 and 8 form a group of jaw clutches, and when the fan 4 is positioned at the outer end of the screw rod 3, the two groups of

teeth

6 and 8 can be mutually meshed.
