AI Technical Summary
In the existing technology, the air outlets directly impact the canvas during the air supply of the chute in the material supply workshop, causing damage to the canvas and affecting the material flow of the chute and the control of environmental data.
A wind deflector is installed inside the duct, equipped with a sliding groove and a sealing cover. The wind deflector is slidably installed through the sliding groove to disperse the wind force and avoid direct impact on the canvas, and the sealing cover enhances the airtightness.
This effectively avoids direct impact from the air vents on the canvas, reduces canvas damage, and improves the ventilation volume and environmental data stability of the chute channel.

Abstract
Description
Technical Field
[0001] This utility model relates to a protective device for installing canvas on a chute, belonging to the field of electrolytic aluminum technology. Background Technology
[0002] In the electrolytic aluminum production process, the canvas between the chute and the ductwork plays a crucial role. The canvas effectively prevents air backflow, ensuring normal air circulation and avoiding problems such as deterioration of indoor air quality and abnormal temperature. This is particularly important for the electrolytic aluminum production environment, as the process may generate certain pollutants; the filtration function of the canvas protects workers' health and improves the quality of the working environment.
[0003] In the process of realizing the technical solution of this application, the inventors discovered that the prior art has at least the following technical problems:
[0004] The air supply pipeline of the chute in the material supply workshop has a high pressure. If the air outlet is directly facing the canvas during the air supply period of the chute, it will have a great impact on the canvas, which can easily cause damage to the canvas, affect the material flow of the chute, and make it difficult to control the environmental data. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a protective device for installing canvas in a chute to avoid the air vent directly impacting the canvas.
[0006] The protective device for installing canvas on a chute according to this utility model includes a chute channel, a duct connected to one side of the chute channel, a canvas installed between the duct and the chute channel, a wind deflector installed inside the square-arranged duct, the wind deflector being installed close to the canvas, and several ventilation openings opened on the wind deflector.
[0007] Furthermore, a through groove is provided on the air duct, and a baffle plate is slidably installed in the groove.
[0008] Furthermore, a sealing cover is provided on the duct corresponding to the sliding groove.
[0009] Furthermore, the sealing cap is detachable.
[0010] Furthermore, the canvas is arranged at an angle.
[0011] Furthermore, the distance β between the windshield and the canvas is no greater than 200mm.
[0012] Furthermore, the ventilation opening can be made into a keyway hole, a circular hole, or a square hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention disperses the concentrated airflow by installing a baffle plate inside the air duct, thereby preventing the air outlet from directly impacting the canvas and further avoiding damage to the canvas. Attached Figure Description

[0026] Example 1
[0027] like Figures 1-5 As shown, the chute canvas installation protection device of this utility model includes a chute channel 1, a duct 2 connected to one side of the chute channel 1, a canvas 5 installed between the duct 2 and the chute channel 1, a wind baffle 4 installed inside the square-arranged duct 2, the wind baffle 4 is installed close to the canvas 5, and a plurality of ventilation openings 41 are provided on the wind baffle 4.
[0028] The air duct 2 has a through groove 21, and the wind baffle 4 is slidably installed in the groove 21. The wind baffle 4 can be slidably installed and then welded, so that it cannot be disassembled later.
[0029] A sealing cover 3 is provided on the air duct 2 corresponding to the slide groove 21, and a sealing gasket 31 is placed between the sealing cover 3 and the air duct 2 to enhance the seal.
[0030] The sealing cover 3 is detachable and is installed on the air duct 2 with screws. The upper and lower parts are set accordingly. The sliding groove 21 can also be opened on both sides.
[0031] The canvas 5 is arranged at an angle, allowing the feed material to fall directly onto the canvas, which increases the filtration area and the ventilation volume in the chute channel 1.
[0032] like Figure 5 As shown, the distance β between the wind deflector 4 and the canvas 5 should not exceed 200mm. If the distance is too far, it will easily affect the performance of the wind deflector 4.
[0033] In this embodiment, the ventilation opening 41 is a keyway hole.
[0034] Working process or working principle:
[0035] During installation, first install the lower sealing cover 3 onto the air duct 2, then insert the wind baffle 4 into the upper groove 21 of the air duct 2, and finally install the upper sealing cover 3 of the air duct 2. The airflow can be dispersed through the ventilation port 41, thereby reducing the impact on the canvas 5 and preventing damage to the canvas 5.
[0036] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
