Description

Technical Field

[0001] The utility model relates to the technical field of automatic control of air dampers, in particular to a control component for the air damper of a smoke pipe of a stenter. Background Technique

[0002] The high-efficiency fiber filter system is a currently widely used waste gas treatment technology, which is 30%-40% more energy-efficient than traditional electrostatic purifiers in terms of energy conservation. By setting the actual negative pressure used, the operating frequency of the fan is regulated to achieve energy-saving effects. And by controlling the size of the air damper of the smoke pipe of the stenter through a control valve, energy can be effectively saved. Conventionally, the size of the air damper of the smoke pipe of the stenter is controlled by means such as manual or cylinder drive. However, the manual type has low precision (as can be seen in the attached Figure 6 shown). The whole set requires manual adjustment, which is not only cumbersome but also has poor adjustment accuracy; or a cylinder is used, but there is a time difference in the control of the intake and exhaust of the cylinder, which affects the control accuracy, and the cylinder is prone to aging and cracking under high temperature, affecting the function.

[0003] To solve the above problems, this case came into being. Content of the Utility Model

[0021] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0022] Such as Figure 1-2As shown: a smoke duct damper control assembly of a setting machine, which is arranged on the smoke duct damper side of the fan 3, the smoke duct damper is provided with a plurality of lateral arrays of air ports 6, each of which is provided with a blade, a rotating shaft 7 is laterally pivoted on the smoke duct damper, the rotating shaft 7 is connected to the outer blades, and the blades are rotated by driving the rotating shaft 7. It should be noted that the applied damper illustration only shows the improved part, not the actual full picture.

[0023] like Figure 3 As shown: the control component includes an electric cylinder 8 arranged on the smoke pipe damper, and the output end of the electric cylinder 8 is connected to a push-pull flexible shaft 9. The far end of the push-pull flexible shaft 9 (similar to the water pipes at home, the hardness is strengthened inside, and the whole is still deformable) passes through the supporting outer wall of the smoke pipe damper, and a connecting seat 10 is provided at the penetration point, so that the force of the push-pull flexible shaft 9 is converted from the horizontal direction to the vertical direction. The push-pull flexible shaft 9 is located below the connecting seat 10 in a vertical state, and the lower end of the push-pull flexible shaft 9 is hinged with a rotating rod 11, wherein the rotating shaft 7 that passes through the smoke pipe damper extends to its outside, and the other end of the rotating rod 11 is connected to the outer end of the rotating shaft 7, so that the electric cylinder 8 can quickly transmit the force to the rotating rod 11 by pulling the push-pull flexible shaft 9 horizontally, so as to realize the rotation of the rotating shaft 7 and then control the flexible control air outlet 6 to adjust the size of the air outlet (similar to the effect of the air valve).

[0024] The connecting seat 10 is mainly fixed to the supporting outer wall, and is provided with a through hole whose size is larger than the push-pull flexible shaft 9, so that the direction of the push-pull flexible shaft 9 can be limited and converted.

[0025] Since the smoke duct damper is provided with multiple rows in the vertical direction, considering the problem of long-distance assembly angle, when connecting the rotating shaft 7 of the smoke duct damper below, because the distance between the straight up and straight down is different, it needs to be set to be inclined (or the upper section is set to be inclined, and one section can be slightly inclined), that is, a completely vertical angle is easy to stagger and produce an obstruction. Therefore, the inclined section of the push-pull flexible shaft 9 needs to be limited in the direction of rotation, which is achieved by the connecting seat 2 12 fixed to the side wall of the smoke duct damper. The connecting seat 2 12 is the same model as the connecting seat 1 10, only the fixed angle is different, that is, the connecting seat 1 10 is arranged horizontally, and the connecting seat 2 12 is arranged obliquely.

[0026] The push-pull flexible shaft 9 is about 2 meters long in actual application. Considering the long-distance connection problem of the push-pull flexible shaft 9, straight rods are connected at both ends to connect the ends, and the ends are tightly wrapped and fixed in a conventional clamping manner.

[0027] Furthermore, since the horizontal smoke duct dampers are staggered, in order to continue the horizontal joint control of the control components, please refer to the attached Figure 6 As shown, a connecting rod 14 with an angle of 90° is connected between two adjacent rotating shafts 7 through a joint, and the distal ends of the two connecting rods 14 are connected to a cross bar 13, thereby realizing the linkage of the two rotating shafts 7.

[0028] By electrically controlling the size of the smoke pipe damper of the stenter through the electric control valve 5, energy conservation can be effectively achieved, that is, the control components of the smoke pipe dampers individually control multiple smoke pipe dampers, and the multiple air outlets 6 in the axial direction are controlled in parallel, so that the air volume can be flexibly adjusted, effectively reducing the energy consumption of the stenter. Moreover, the reduction of the exhaust air can effectively control the stenter to reduce heat emission while discharging moisture, thereby optimally controlling the energy consumption of the stenter. Specifically, the application of the electric cylinder 8 and the push-pull flexible shaft 9 has sensitive feedback, high adjustment accuracy, convenient subsequent maintenance and lower cost.

[0029] Based on the above embodiments as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the idea of this invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
