Description

Technical Field

[0001] This utility model belongs to the field of material screening technology, and specifically relates to a horizontal air separator. Background Technology

[0002] A horizontal air separator is a device that utilizes horizontal airflow to control the separation effect of materials by controlling the air velocity and particle size of the material. While existing horizontal air separators can meet the basic requirements for air separation of materials, they typically use a dispersing structure to break up all the material during the feeding process. In reality, only agglomerated material needs to be broken up, leading to a significant amount of wasted work on the dispersing structure and affecting the feeding efficiency, thus impacting the overall air separation efficiency. Therefore, they cannot fully meet the needs of users.

[0003] For example, the utility model patent with announcement number CN219965607U discloses a horizontal air classifier. In the technical solution of this patent document, a dispersing rod is set inside the fixed box. The material is introduced into the fixed box through the feed port, and then the dispersing rod disperses the material, which facilitates the rapid sorting of the material inside the box. However, since all the material is directly dispersed, the dispersing structure will ineffectively disperse a large amount of material that does not need to be dispersed, which will affect the feeding efficiency and thus the overall efficiency of air classification, thus causing great inconvenience to users. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a horizontal air classifier, which not only meets the basic requirements for air classification of materials, but also enables the dispersing structure to only dissolve agglomerated materials that need to be dispersed, thereby avoiding affecting the overall efficiency of feeding and air classification.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a horizontal air classifier, including a horizontal air classifier body, a feeding cylinder provided at the top of the air classifier body, a support provided at the top of the air classifier body, a feeding box with a top opening vertically vibrating on the support, a screen cylinder provided inside the feeding box, a feeding pipe provided at the bottom of the feeding box, a feeding hopper also provided at the top of the air classifier body, a dispersing shaft extending to the upper side of the feeding hopper rotatably provided in the screen cylinder, and dispersing blades provided on the dispersing shaft.

[0006] As a further improvement of this invention, the lower end of the feed cylinder is conical, which allows for faster and more thorough discharge of screened or dispersed materials.

[0007] As a further improvement of this utility model, an extension plate is provided on the side of the feeding box, and multiple springs are provided between the support and the extension plate. A vibration motor is also provided on the extension plate, and a guide unit is provided between the support and the extension plate. The guide unit includes a guide slot provided on the support, and a guide plate provided on the extension plate that inserts into the guide slot. The vibration motor and multiple springs can drive the feeding box to vibrate; the vertical insertion and cooperation of the guide slot and the guide plate can make the feeding box vibrate vertically smoothly, avoiding easy deformation and damage to the springs.

[0008] As a further improvement of this utility model, the top of the feeding box is also provided with a mounting frame that spans the feeding hopper, and the upper end of the dispersing shaft passes through the mounting frame and is rotatably connected to the mounting frame.

[0009] As a further improvement of this utility model, the top of the air separator body is also provided with a fixed frame that spans the mounting frame. A telescopic push rod is vertically arranged on the fixed frame. A horizontal plate is provided at the lower end of the output shaft of the telescopic push rod. A spiral cylinder is arranged on the horizontal plate. The top of the dispersing shaft is also provided with a spiral rod that can be screwed onto the spiral cylinder. Because the feeding box can stably vibrate vertically under the guidance of the guiding unit, the spiral cylinder can stably drive the spiral rod, the dispersing shaft and the dispersing blades to rotate.

[0010] As a further improvement of this utility model, a guide cylinder is also provided on the fixing frame, and a guide rod is provided on the horizontal plate to be inserted into the guide cylinder. Through the insertion and cooperation of the guide cylinder and the guide rod, the horizontal plate and the spiral cylinder can move vertically smoothly, and the telescopic push rod can be prevented from being easily damaged by terrain deformation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Firstly, the dispersing shaft and dispersing blades can be driven to rotate but the feeding box and screen cylinder can be driven to vibrate vertically to screen the material. This allows a large amount of material that does not need to be dispersed to leave the screen cylinder and feeding box and enter the air classifier for air separation. Then, the dispersing shaft and dispersing blades can be driven to rotate to disperse the agglomerated material trapped in the screen cylinder.

[0013] Secondly, the vertical position of the screw cylinder can be flexibly adjusted by the telescopic push rod, realizing or de-connecting the screw cylinder and the screw rod, realizing or de-connecting the rotation drive of the screw rod, the dispersing shaft and the dispersing blades, so that the dispersing shaft and the dispersing blades only rotate when it is necessary to dissolve the agglomerated material.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, a horizontal air classifier includes a horizontal air classifier body 101. A feed cylinder 102 is located at the top of the air classifier body 101, and a support 103 is also located at the top of the air classifier body 101. A feeding box 104 with a top opening is vertically vibrating on the support 103. A filter cylinder 105 is installed inside the feeding box 104 via a connecting plate 112. Both ends of the connecting plate 112 are fixedly connected to the feeding box 104 and the filter cylinder 105, respectively. A feeding pipe 106 is located at the bottom of the feeding box 104. A feeding hopper 107 is also located at the top of the air classifier body 101. A dispersing shaft 108 extending to the upper side of the feeding hopper 107 is rotatably installed in the filter cylinder 105. Dispersing blades 109 are installed on the dispersing shaft 108. The lower end of the feed cylinder 102 is conical.

[0022] The dispersing shaft 108 and dispersing blades 109 can be driven to rotate without first driving them to rotate. Only the feeding box 104 and the screen cylinder 105 can be driven to vibrate vertically. Then, the material is added to the screen cylinder 105 through the feeding hopper. Small particles will pass directly through the screen holes of the screen cylinder 105 and fall into the feeding box 104. Then, they will fall into the air classifier body 101 through the feeding pipe 106 and the feeding cylinder 102 for air classification. Large particles that are agglomerated will be intercepted because they cannot pass through the screen holes of the screen cylinder 105.

[0023] When a large amount of agglomerated material is trapped in the filter cylinder 105, the dispersing shaft 108 can be rotated to cause the dispersing shaft 108 and the dispersing blades 109 to dissolve the agglomerated material trapped in the filter cylinder 105.

[0024] like Figure 1 As shown, an extension plate 201 is provided on the side of the feeding box 104. Multiple springs 202 are arranged between the support 103 and the extension plate 201. A vibration motor 203 is also provided on the extension plate 201, and a guide unit is also provided between the support 103 and the extension plate 201. The guide unit includes a guide slot 204 on the support 103 and a guide plate 205 on the extension plate 201 that inserts into the guide slot 204. By simply starting the vibration motor 203, the feeding box 104 and the filter cylinder 105 can be driven to vibrate stably vertically with the cooperation of the multiple springs 202 and the vertical insertion of the guide slot 204 and the guide plate 205, thus preventing the springs 202 from easily deforming and being damaged.

[0025] According to another embodiment of the present invention, such as Figure 3 As shown, the top of the feeding box 104 is also provided with a mounting frame 110 spanning the feed hopper. The upper end of the dispersing shaft 108 passes through and is rotatably connected to the mounting frame 110 via a bearing 111. The outer ring of the bearing 111 is connected to the top of the mounting frame 110, and the inner ring of the bearing 111 is connected to the outer side wall of the dispersing shaft 108. The mounting frame 110 has a through hole that is rotatably connected to the dispersing shaft 108. Through the engagement of the through hole of the bearing 111, the dispersing shaft 108 can be rotated and supported.

[0026] According to another embodiment of the present invention, such as Figure 3 , 4As shown, the top of the air separator body 101 is also provided with a fixed frame 301 that spans the mounting frame 110. A telescopic push rod 302 is vertically arranged on the fixed frame 301. A horizontal plate 303 is provided at the lower end of the output shaft of the telescopic push rod 302. A spiral cylinder 304 is arranged on the horizontal plate 303. A spiral rod 305 that can be screwed to the spiral cylinder 304 is also provided at the top of the dispersing shaft 108. Because the feeding box 104 can stably vibrate vertically under the guidance of the guiding unit, the spiral cylinder 304 can stably drive the spiral rod 305, the dispersing shaft 108 and the dispersing blades 109 to rotate.

[0027] During the process of driving the screw cylinder 304 downward by the telescopic push rod 302, it is not necessary to stop the feeding box 104 from vibrating, because this will not affect the screw connection between the screw cylinder 304 and the screw rod 305. It will only directly drive the screw shaft to rotate.

[0028] When the dispersing shaft 108 needs to be rotated, the output shaft of the telescopic push rod 302 can be driven to extend downward by a certain length, causing the horizontal plate 303 and the screw cylinder 304 to move vertically a certain distance, so that the screw cylinder 304 is screwed into the screw rod 305. At the same time, the vertical vibration drive of the feeding box 104 and the screen cylinder 105 is maintained. The screw rod 305 will move up and down vertically relative to the screw cylinder 304, so that the screw cylinder 304 drives the screw rod 305, the dispersing shaft 108 and the dispersing blades 109 to rotate in both forward and reverse directions, thereby realizing the rotation drive of the screw rod 305, the dispersing shaft 108 and the dispersing blades 109.

[0029] When there is no need to drive the dispersing shaft 108 to rotate, simply drive the output axis of the telescopic push rod 302 to shorten by a certain length, which will allow the spiral cylinder 304 to return to its original position and separate from the spiral rod 305, thus pausing the rotation drive of the spiral rod 305. Therefore, the technical solution of this application can only rotate when it is necessary to disperse agglomerated materials.

[0030] According to another embodiment of the present invention, such as Figure 3 , 4 As shown, the fixed frame 301 is also provided with a guide tube 306, and the horizontal plate 303 is provided with a guide rod 307 that is inserted into the guide tube 306. Through the insertion and cooperation of the guide tube 306 and the guide rod 307, the horizontal plate 303 and the spiral cylinder 304 can move vertically smoothly, and the telescopic push rod 302 is prevented from being easily damaged by terrain deformation.

[0031] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
