Description

Technical Field

[0001] The present invention relates to the technical field of exhaust equipment, and in particular to a slotted jet air supply outlet with adjustable direction. Background Art

[0002] The local exhaust hood is the most commonly used and effective end exhaust equipment for removing industrial local pollutants. However, the wide suction range of the traditional local exhaust device leads to the problems of fast attenuation of its suction momentum, low pollutant capture performance, and high energy consumption. In order to improve the performance of the square-opening local exhaust hood, active airflow can be used to limit the suction confluence range of the exhaust hood, improve the pollutant capture efficiency, and reduce energy consumption.

[0003] If active airflow is to be effectively generated, the currently widely used one is the fixed deflector slotted air outlet. However, industrial pollution sources have the characteristics of complexity and variability. The traditional fixed deflector slotted air outlet cannot adjust the jet outflow angle according to the characteristics of the pollution source and the installation distance of the exhaust equipment, and can only supply air in a single direction. This makes the jet unable to adapt to the changes of the pollution source and play the best role. Research shows that different jet angles will change the critical velocity at which the jet acts, and will also change the effective suction range and effective suction distance of the exhaust equipment. Therefore, in order to adapt to more pollutant emission scenarios and emission conditions, in order to effectively exert the performance of the exhaust equipment and reduce the exhaust and jet energy consumption, it is necessary to solve the problem of the fixed jet outflow angle of the traditional jet air outlet.

[0004] Due to the characteristic of the small width of the above-mentioned air outlet, the commonly used width is 4-12 mm, so the traditional method of changing the angle of the supply and exhaust air outlet cannot be applied to the above-mentioned jet air outlet. Therefore, it is necessary to study other methods to adjust the angle of the slotted air outlet to improve the performance of industrial exhaust equipment and reduce the exhaust energy consumption. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawback that the traditional method of changing the angle of the supply and exhaust air outlet cannot be applied to the above-mentioned jet air outlet. Therefore, it is necessary to study other methods to adjust the angle of the slotted air outlet to improve the performance of industrial exhaust equipment and reduce the exhaust energy consumption, and a slotted jet air supply outlet with adjustable direction is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A slotted jet air supply outlet with adjustable direction, comprising:

[0008] An inner cavity body and an outer shell body. An arc-shaped structure of the inner cavity body is arranged on the outer side of the inner cavity body. An arc-shaped structure of the outer shell body is provided on the inner side of the outer shell body. The outer side of the arc-shaped structure of the inner cavity body is slidably connected to the inner wall of the arc-shaped structure of the outer shell body. A matching cavity is provided on both sides of the outer shell body. A notch is provided on the outer side of one of the two matching cavities. A jet cavity is provided on the outer side of the inner cavity body. A diversion structure is arranged on the outer side of the inner cavity body. The diversion structure and the jet cavity are symmetrically arranged. The diversion structure is movably connected to the matching cavity through the notch;

[0009] A circular plate is fixedly installed on the outer side of the inner cavity body. An annular groove is provided on the circular plate. An arc-shaped missing strip is fixedly installed on the outer side of the outer shell body. The arc-shaped missing strip is slidably connected to the inner wall of the annular groove.

[0010] Preferably, a diversion opening is provided on the diversion structure for air flow diversion.

[0011] Preferably, two connecting pieces are symmetrically and fixedly installed on the outer side of the outer shell body for installing the whole.

[0012] Preferably, a circular groove is provided on the inner wall of the outer shell body. A first magnetic column is fixedly installed at one end of the inner cavity body. A second magnetic column is fixedly installed on the inner wall of the circular groove. The first magnetic column is rotatably connected to the circular groove and attracted to the second magnetic column, attracting the inner cavity body inside the outer shell body.

[0013] Preferably, two elastic grooves are symmetrically provided on the inner wall of the annular groove. Elastic rods are slidably installed in both elastic grooves. Triangular blocks are fixedly installed on the outer sides of both elastic rods. A plurality of triangular grooves are provided on the inner wall of the arc-shaped missing strip. The two triangular blocks are adapted to the plurality of triangular grooves. Springs are fixedly installed at the outer ends of the elastic rods. The springs are fixedly installed on the inner walls of the elastic grooves.

[0014] Preferably, a receiving groove is provided on the outer side of the circular plate. A handle is rotatably installed in the receiving groove. The handle is of an n-shaped structure. Rotating shafts are fixedly installed at both ends of the handle. Both rotating shafts are rotatably connected to the receiving groove.

[0015] Preferably, two finger grooves are provided on the inner wall of the receiving groove. Two clamping blocks are fixedly installed in the finger grooves. Arc-shaped clamping grooves are locked on both clamping blocks. The handle is adapted to the two arc-shaped clamping grooves; the handle is pushed into the receiving groove and fixed by the two clamping blocks.

[0016] During use, insert the inner cavity body into the outer shell body. The flow guiding structure is inserted into the fitting cavity through the notch, and the arc-shaped strip enters the annular groove. Due to the elastic force of the spring, the triangular block is inserted into the triangular groove. Through the attraction between the second magnetic column and the first magnetic column, the stability of the inner cavity body in the outer shell body is improved. Use two finger grooves to pick out the handle. The handle leaves the receiving groove, and then rotate the handle to drive the circular plate to rotate. The circular plate drives the inner cavity body to rotate, and the jet cavity on the inner cavity body is misaligned with the fitting cavity to adjust the angle of the air supply port. During rotation, the triangular block enters from one triangular groove into another triangular groove to improve the stability after angle adjustment. Then push the handle into the receiving groove and fix the handle by two clamping blocks. When disassembling, pull out the inner cavity body from the outer shell body through the handle for replacement.

[0017] In the present invention, the beneficial effects of the adjustable slotted jet air supply port are as follows:

[0018] 1. Through the coordinated setting of the inner cavity body, the outer shell body, the air supply device, and the exhaust device, the adjustable slotted jet air outlet is enabled to form a jet air curtain and has the function of adjusting the direction of the air curtain. The formation of the air curtain can enhance the effect of the exhaust device in removing pollutants and reduce the energy consumption of the equipment. Air is transported to the jet cavity through the air supply pipe, and the air flows out through the jet port flow guiding structure to form an air curtain.

[0019] 2. Compared with the traditional slotted air outlet, the air flow ejected from the jet cavity can play a role in adjusting the outflow angle and can adapt to more pollutant emission scenarios. And compared with the traditional fixed disposable exhaust air outlet, the inner cavity body of this air outlet can be disassembled and replaced with the inner cavity body of different slotted sizes. The disassembled inner cavity body can be recycled, which is environmentally friendly.

[0020] The present invention can rotate the inner cavity body through the arc-shaped structure to adjust the angle of the slotted jet port, thereby adjusting the effective suction distance and effective suction range of pollutants of the exhaust device, and being able to change the required exhaust air volume of the exhaust device and the required air supply volume of the jet. The adjustment of the jet outflow angle and the replaceability of the inner cavity body enable the present invention to have the characteristics of flexible applicable scenarios, simple structure of the air outlet itself, and strong practicability.
