Description

Technical Field

[0001] This utility model belongs to the field of tension screen technology, and specifically relates to a tension screen for preventing material blockage. Background Technology

[0002] Currently, tension screens are screening machines that use the relaxing and relaxing motion of an elastic screen surface mounted on an inclined screen box to throw materials. This "relaxation" refers to the loosening or stretching of the material, allowing for the screening of fine, sticky, and wet materials that are difficult to screen. While existing tension screens can meet the basic requirements for material screening and can prevent material from concentrating on a limited area of ​​the screen surface through a material dispersion structure, thus avoiding affecting screening efficiency, the diversion structure used is often fixed. This can easily lead to some material adhering to the diversion structure, affecting the diversion effect and consequently the screening effect.

[0003] For example, the utility model patent with announcement number CN220361518U discloses a tension screen. In the technical solution of this patent document, the material that is about to fall on the tension screen body is diverted by a guide chamber fixedly set at the upper end of the feed inlet of the tension screen body and a diversion block fixed on the guide chamber. However, since the guide chamber is fixedly set above the tension screen body, the material can easily get stuck and adhere to the inner wall of the guide chamber and the diversion block, thereby affecting the subsequent diversion effect of the material and the screening effect of the material. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tension screen that prevents material blockage. It not only meets the basic requirements for screening materials, but also prevents materials from adhering to the diversion structure and affecting the diversion and screening effects while performing material diversion.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tension screen for preventing material blockage, including a base, a tension screen body disposed on the base, and a diversion module located above the feed inlet of the tension screen body on the base. The diversion module includes a support plate slidably disposed on the base and located on the left and right sides of the tension screen body. A support frame is disposed on the support plate above the feed inlet of the tension screen body. Multiple springs are vertically disposed on the support frame. Mounting frames are disposed on the multiple springs. A diversion cylinder and a vibration motor are disposed on the mounting frames.

[0006] As a further improvement of this utility model, a connecting groove is provided on the base below a support plate, and a connecting slider is provided on the bottom of the support plate, which is slidably connected to the connecting groove. A linear slide is also provided on the base along the front-back direction below another support plate, and the slide seat of the linear slide is connected to the support plate. Through the cooperation of the connecting groove, the connecting slider, and the linear slide, the support plate, the support frame, and the flow divider can be reciprocated and adjusted in the front-back direction.

[0007] As a further improvement of this invention, both the connecting groove and the connecting slider have T-shaped vertical cross-sections. This effectively avoids problems such as the connecting slider tilting relative to the connecting groove, allowing the device to maintain better stability.

[0008] As a further improvement of this utility model, the mounting frame is also provided with a fixing frame that spans across the top of the diversion cylinder. A stirring shaft that extends vertically through and rotatably onto the fixing frame and extends to the lower end of the interior of the diversion cylinder is provided. The stirring shaft is provided with stirring blades that are adapted to the diversion cylinder.

[0009] As a further improvement of this invention, a scraper is also provided on the side end of the stirring blade for scraping and cleaning the material adhering to the inner wall of the distribution cylinder. The scraper facilitates the easy scraping and cleaning of the material adhering to the inner wall of the distribution cylinder.

[0010] As a further improvement of this utility model, a drive motor is provided on the fixed frame, a drive gear is provided on the output shaft of the drive motor, and a driven gear that meshes with the drive gear is provided at the lower end of the stirring shaft.

[0011] As a further improvement of this utility model, a feed hopper is also provided at the upper end of the diverter cylinder, and the lower end of the diverter cylinder is conical. The feed hopper allows for easier addition of materials into the diverter cylinder; because the lower end of the diverter cylinder is conical, it prevents materials entering the diverter cylinder from rapidly leaving the diverter cylinder, thus allowing the diverter cylinder to distribute materials to different areas of the feed inlet of the tension screen body, better preventing material accumulation.

[0012] As a further improvement of this utility model, the support frame is also provided with a guide slot, and the mounting frame is also provided with a guide plate that is inserted and connected to the guide slot. Through the insertion and cooperation of the guide slot and the guide plate, the mounting frame and the diverter cylinder can vibrate vertically smoothly, avoiding lateral displacement and preventing multiple springs from being easily damaged by deformation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, it enables the support plate, support frame, mounting frame, and distribution cylinder to reciprocate in the front-to-back direction, thereby scattering the material at different positions in the feed inlet of the tension screen body, changing and expanding the material drop range, and avoiding material accumulation at the feed inlet of the tension screen body, thus avoiding affecting the screening efficiency; and through the cooperation of the vibrating motor and multiple springs, the distribution cylinder and the material vibrate, effectively preventing the material from easily clogging and adhering in the distribution cylinder, so that the material falls smoothly onto the tension screen body for screening.

[0015] Secondly, the stirring shaft and stirring blades can disperse the material entering the diversion cylinder, preventing the material from clumping and affecting the material discharge process from the diversion cylinder, and also preventing the subsequent screening effect and screening efficiency from being affected.

Detailed Implementation

[0022] 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.

[0023] like Figure 1 , 2 As shown, a tension screen for preventing material blockage includes a base 101. A tension screen body 102 is mounted on the base 101 via a support rod 103. A diversion module is also mounted on the base 101 at the upper end of the feed inlet of the tension screen body 102. The diversion module includes a support plate 201 slidably mounted on the base 101 and located on the left and right sides of the tension screen body 102. A support frame 202 is mounted on the support plate 201 above the feed inlet of the tension screen body 102. Multiple springs 203 are vertically mounted on the support frame 202. A mounting frame 204 is mounted on the multiple springs 203. A diversion cylinder 205 and a vibration motor 206 are mounted on the mounting frame 204.

[0024] like Figure 1 As shown, a connecting groove 207 is provided on the base 101 below a support plate 201, and a connecting slider 208 is provided at the bottom of the support plate 201 that is slidably connected to the connecting groove 207. A linear slide 209 is also provided on the base 101 along the front-back direction below another support plate 201, and the slide of the linear slide 209 is connected to the support plate 201.

[0025] The worker can first drive the linear slide table 209 to move back and forth, causing the support plate 201 and the connecting slider 208 to slide relative to the connecting groove 207, thereby driving the mounting frame 204 and the diverting cylinder 205 to move back and forth in the front and back direction. At the same time, the material is added into the diverting cylinder. Thus, the diverting cylinder 205, which moves back and forth in the front and back direction, causes the material to fall at different positions at the feed inlet of the tension screen body 102, avoiding the material from continuously concentrating at a fixed position on the tension screen body 102, thus avoiding affecting the screening effect and efficiency.

[0026] At the same time, the vibration motor 206 can be started, and with the cooperation of multiple springs 203, the diversion cylinder 205 and the material will vibrate vertically, which effectively prevents the material from easily getting blocked and stuck in the diversion cylinder, and allows the material to fall smoothly onto the tension screen body 102 for screening.

[0027] Both the connecting groove 207 and the connecting slider 208 have T-shaped vertical cross-sections. This effectively prevents the connecting slider 208 from tilting relative to the connecting groove 207, thus ensuring better stability of the device.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 3, a fixing frame 301 is welded across the top of the diversion cylinder 205 on the mounting frame 204. The fixing frame 301 is U-shaped. A stirring shaft 302 extending to the lower end of the interior of the diversion cylinder 205 is vertically inserted and rotatably mounted on the fixing frame 301 through a bearing 304. The outer ring of the bearing 304 is connected to the top of the fixing frame 301, and the inner ring of the bearing 304 is connected to the upper outer wall of the stirring shaft 302. A through hole 306 is provided on the top of the fixing frame 301 for rotatably connecting with the stirring shaft 302.

[0029] The stirring shaft 302 is equipped with stirring blades 303 that are compatible with the diversion cylinder 205. Simply rotating the stirring shaft 302 will drive the stirring blades 303 to rotate, which can agitate and disperse the material entering the diversion cylinder 205, preventing the material from agglomerating and affecting the material discharge process from the diversion cylinder 205, and also preventing any impact on the subsequent screening effect and efficiency.

[0030] According to another embodiment of the present invention, such as Figure 3 As shown, the side end of the stirring blade 303 is also provided with a scraper 305 for scraping and cleaning the material adhering to the inner wall of the diversion cylinder 205. The stirring blade 303 can drive the scraper 305 to rotate and scrape and clean the material adhering to the inner wall of the diversion cylinder 205.

[0031] A drive motor is mounted on the fixed frame 301, and a drive gear is mounted on the output shaft of the drive motor. A driven gear that meshes with the drive gear is mounted on the lower end of the stirring shaft 302. By simply starting the drive motor, the stirring shaft 302 can be driven to rotate through the transmission action of the drive gear and the driven gear.

[0032] According to another embodiment of the present invention, such as Figure 4 As shown, a feed hopper 307 is also provided at the upper end of the diversion cylinder 205, and the lower end of the diversion cylinder 205 is conical. The feed hopper 307 makes it easier to add materials into the diversion cylinder 205; since the lower end of the diversion cylinder 205 is conical, it can prevent the materials entering the diversion cylinder 205 from leaving the diversion cylinder 205 too quickly, so that the diversion cylinder 205 can disperse the materials to different areas of the feed inlet of the tension screen body 102, and better avoid material accumulation.

[0033] According to another embodiment of the present invention, such as Figure 1 , 2As shown, the support frame 202 is also provided with a guide slot 210, and the mounting frame 204 is also provided with a guide plate 211 that is inserted and connected to the guide slot 210. Through the cooperation of the vibration motor 206 and multiple springs 203, during the vibration driving process of the mounting frame 204 and the diverter cylinder 205, the guide plate 211 can slide vertically relative to the guide slot 210, thereby driving the mounting frame 204 and the diverter cylinder 205 to vibrate smoothly vertically, avoiding lateral displacement, preventing the diverter cylinder 205 from colliding with the support frame 202, and preventing the multiple springs 203 from being easily damaged by deformation.

[0034] 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.
