Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, and more specifically, to a raw material screening device. Background Art

[0002] A raw material screening device is a device used for separating and screening raw materials. The main function of the raw material screening device is to classify the raw materials into different particle size levels or remove impurities therein according to the size, shape and other characteristics of the raw materials. The raw material screening device usually consists of one or more sieve meshes with many small holes or pores. When the raw materials pass through the device, the smaller particles or impurities will fall into the collector below through the pores of the sieve mesh, while the larger particles will be blocked by the sieve mesh and retained above. In this way, the raw materials can be separated and classified according to their particle size distribution to achieve the screening effect. Since some material particles are attached with some impurities with lighter mass on their surfaces, it is necessary to screen and remove the impurities from the material particles.

[0003] In the related art, during the use of the raw material screening device, generally one or more vibration motors are driven to generate a vibration force in the vertical or horizontal direction, so that the raw materials move quickly on the sieve mesh to achieve separation and screening, thereby carrying out screening.

[0004] However, during the use of the current raw material screening device, due to the impurities with lighter mass attached to the surface of the material particles, they are prone to fly up and contact the screened materials again during the material screening process and are discharged, resulting in difficulty in cleaning and removing the lighter impurities during the material screening process, affecting the screening effect of the materials and the convenience of impurity removal.

Therefore, the screening and impurity removing effect of the screening box 2 is improved.

[0032] Referring to Figures 1-4 , in a preferred embodiment, the blowing and impurity removing structure includes a blowing cylinder 5. The blowing cylinder 5 is fixedly connected to the front side of the screening box 2. A blowing fan 6 electrically connected to the controller 4 is fixedly connected inside the blowing cylinder 5.

An adsorption and impurity collection mechanism is fixedly connected to the bottom of the rear side of the screening box 2. By starting the blowing fan 6 through the controller 4 to perform a blowing operation on the impurities attached to the surface of the material on top of the screening mesh 3. At this time, the filter frames 7 block the material from entering the inside of the blowing cylinder 5. At the same time, the impurities that move towards the rear side of the screening box 2 under the influence of the wind of the blowing fan 6 enter the inside of the filter impurity cylinder 8. At this time, the filter impurity cylinder 8 cooperates with the filter impurity plate 9 to filter the impurities blown by the blowing fan 6. The adsorption and impurity collection mechanism includes a fixed seat 10, an adsorption box 11, and an impurity collection port 12. The fixed seat 10 is fixedly connected to the bottom of the rear side of the screening box 2. The fixed seat 10 is located at the bottom of the filter impurity cylinder 8. The adsorption box 11 is movably connected to the top of the fixed seat 10. The impurity collection port 12 is opened on the top of the adsorption box 11. When the filter impurity cylinder 8 cooperates with the screening box 2, it can perform an adsorption and collection operation on the impurities filtered by the filter impurity plate 9 of the filter impurity cylinder 8, avoiding the situation that it is difficult to collect the impurities after they are discharged from the screening box 2. Therefore, the impurity collection effect of the screening box 2 is improved.

[0033] Referring to Figures 2-3, in a preferred embodiment, a guiding cover 13 communicating with the impurity filtering cylinder 8 is fixedly connected to the rear side of the inner wall of the screening box 2, and a guiding seat 14 contacting the screening net 3 is fixedly connected to the bottom of the rear side of the inner wall of the screening box 2.

Therefore, the impurity removal guiding effect of the screening box 2 is improved. Connecting grooves 15 are respectively formed on both sides of the rear side of the impurity filtering cylinder 8, and connecting bars 16 are movably connected inside the connecting grooves 15. The rear sides of the connecting bars 16 are fixedly connected to the front side of the impurity filtering plate 9. When the impurity filtering plate 9 cooperates with the impurity filtering cylinder 8, it can stabilize the connection between the impurity filtering plate 9 and the impurity filtering cylinder 8, avoiding the situation that the impurity filtering plate 9 separates from the impurity filtering cylinder 8 during operation. Therefore, the working stability of the impurity filtering plate 9 is improved.

[0034] Refer to Figures 2-3 , in a preferred embodiment, a stabilizing groove 17 is formed on the rear side of the top inner wall of the fixing seat 10, and a stabilizing plate 18 is movably connected inside the stabilizing groove 17. The front side of the stabilizing plate 18 contacts the rear side of the adsorption box 11. When the fixing seat 10 cooperates with the adsorption box 11 to work, it can provide a medium for the user to stably install the adsorption box 11 and the fixing seat 10, avoiding the situation that the fixing seat 10 is difficult to effectively stabilize the adsorption box 11 during use.

When the magnetic rings 21 cooperate with the filtering frame 7, it can provide a magnetic positioning medium for the magnetic rings 21, avoiding the situation that the magnetic rings 21 are difficult to effectively apply a magnetic positioning force to the filtering frame 7 during use. Therefore, the magnetic positioning effect of the filtering frame 7 is improved.

[0036] Specifically, the working process or principle of this raw material screening device is as follows: During use, add clear water into the adsorption box 11 through the impurity collection port 12 to prepare for subsequent impurity adsorption. When holding the adsorption box 11 and placing it on the top of the fixed seat 10, at this time, the rubber plate 19 cooperates with the through port 20 to conduct contact sealing and communication work between the adsorption box 11 and the impurity filtering cylinder 8. Then, hold the stabilizing plate 18 and align it with the stabilizing groove 17, and move the stabilizing plate 18 downward into the stabilizing groove 17 to conduct blocking and stabilizing work between the adsorption box 11 and the fixed seat 10. When the screening mesh 3 cooperates with the screening box 2 to work, start the blower fan 6 through the controller 4 to conduct wind blowing work on the impurities adhering to the surface of the material on the top of the screening mesh 3, so as to blow and remove the impurities adhering to the surface of the material particles. At this time, the magnetic ring 21 cooperates with the fixed ring 22 to conduct magnetic attraction positioning work between the filtering frame 7 and the blowing cylinder 5, so that the filtering frame 7 blocks the material from entering the blowing cylinder 5 and contacting the blower fan 6. At this time, the guiding cover 13 cooperates with the guiding seat 14 to conduct guiding work on the impurities that move to the rear side of the screening box 2 under the influence of the wind force of the blower fan 6, so that the impurities enter the impurity filtering cylinder 8. The impurity filtering cylinder 8 cooperates with the impurity filtering plate 9 to conduct filtering work on the impurities blown in by the blower fan 6. At this time, the connecting groove 15 cooperates with the connecting strip 16 to conduct connection and stabilizing work between the impurity filtering plate 9 and the impurity filtering cylinder 8. At the same time, the impurities filtered by the impurity filtering plate 9 enter the adsorption box 11 through the impurity collection port 12 and the through port 20, and the clear water inside the adsorption box 11 conducts adsorption and concentration work on the entering impurities, so that the user can conduct unified cleaning operations later.
