Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a quartz sand purification and impurity separation device that prevents clogging. Background Technology

[0002] Quartz sand is a natural mineral granular material with silicon dioxide as its main component. It is widely found in the Earth's crust and is usually formed by geological processes such as weathering, transportation, and deposition of quartz minerals. It has stable chemical properties and excellent physical properties, making it an indispensable basic material in modern industry. Quartz sand purification and impurity separation equipment is a core industrial equipment specifically designed to remove various impurities from quartz sand and improve its purity. Its core purpose is to transform natural quartz sand or ordinary industrial quartz sand into high-purity quartz sand that meets the needs of high-end fields.

[0003] Traditional quartz sand purification and impurity separation devices typically use a flat single-layer screen structure to filter quartz sand and utilize a vibrating motor to accelerate separation. However, clogging is prone to occur during the quartz sand separation process, leading to a decrease in separation efficiency. Furthermore, frequent cleaning by staff is required, which is time-consuming, labor-intensive, and results in low work efficiency. Utility Model Content

[0004] In order to overcome the problem that traditional quartz sand purification and impurity separation devices are prone to clogging and are difficult to clean, resulting in reduced work efficiency, this utility model provides a clogging-proof quartz sand purification and impurity separation device.

[0005] The technical solution is as follows: A quartz sand purification and impurity separation device for preventing clogging includes a housing for separating and purifying quartz sand. A filter assembly for classifying and purifying the quartz sand is fixedly installed on the inner wall of the housing. Self-cleaning components for blowing off quartz sand clogged on the filter assembly are fixedly installed at opposite positions on the left and right sides of the housing. Three sets of guide pipes for discharging quartz sand are evenly distributed and fixedly installed from top to bottom at the front end of the housing, corresponding to the filter assembly. A control valve for controlling the inlet and outlet is provided on the outer side of the connection between the guide pipes and the housing. A first air pressure controller for controlling the air pressure is fixedly installed on the control valve. The guide pipes are located away from the housing. One end of the box is fixedly connected to a threaded connector for connecting to an external collection device. A sealing ring for increasing airtightness is fitted on the threaded connector. Vibration motors for accelerating separation are detachably installed at the lower parts of the left and right ends of the box. A door for opening and closing is provided at the rear end of the box. A feed hopper for introducing quartz sand is fixedly installed on the side of the upper middle part of the box. A shock absorber for buffering is fixedly installed on the lower middle part of the box. Springs for auxiliary buffering are fixedly installed around the four corners of the lower end of the box. The springs have dampers for auxiliary rebound inside. The springs and shock absorbers are fixedly installed on the base. Mounting holes for mounting the base are opened around the four corners of the upper end of the base.

[0006] Furthermore, the filter assembly includes a first filter frame, a second filter frame, and a third filter frame, which are evenly distributed from top to bottom, and all three filter frames have a stepped structure.

[0007] Furthermore, the first filter frame has first filter holes linearly distributed, the second filter frame has second filter holes linearly distributed, and the third filter frame has third filter holes linearly distributed evenly.

[0008] Furthermore, the pore sizes of the first, second, and third filter pores decrease progressively.

[0009] Furthermore, the self-cleaning component includes a nozzle, a guide tube, a connecting tube, and a second air pressure controller. The nozzle is located on the upper left and right sides of the filter component, and the number and position of the nozzle are matched with the structure of the filter component.

[0010] Furthermore, nozzles located in the same column are fixedly connected and interconnected by guide pipes, and the guide pipes are fixedly connected and interconnected by connecting pipes.

[0011] Furthermore, a second air pressure controller is fixedly installed in the middle of the side of the connecting pipe away from the nozzle.

[0012] Furthermore, the air pressure emitted from the nozzle is controlled by a second air pressure controller.

[0013] The beneficial effects are: This utility model uses a filter assembly with a stepped structure to perform graded filtration of quartz sand. The gradient screening can reduce the accumulation on the screen surface, greatly improve the target particle size capture rate, and improve the separation efficiency.

[0014] By setting up a self-cleaning component that uses air pressure to automatically clean the inside of the chamber, the quartz sand accumulated on the filter components can be sagged down by air pressure, thereby preventing the quartz sand from clogging during the separation process. It can also achieve self-cleaning of the inside of the chamber, avoiding the time-consuming and laborious manual operation. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5As shown, the anti-clogging quartz sand purification and impurity separation device includes a housing 1 for separating and purifying quartz sand. A filter assembly 2 for classifying and purifying the quartz sand is fixedly installed on the inner wall of the housing 1. Self-cleaning components 3 for blowing down quartz sand clogged on the filter assembly 2 are fixedly installed at the left and right ends of the housing 1, corresponding to the positions of the filter assembly 2. Three sets of guide pipes 5 for discharging quartz sand are evenly distributed and fixedly installed from top to bottom at the front end of the housing 1, corresponding to the position of the filter assembly 2. A control valve for controlling the inlet and outlet is provided on the outer side of the connection between the guide pipe 5 and the housing 1. A first air pressure controller 6 for controlling the air pressure is fixedly installed on the control valve. A useful... A threaded connector 7 is connected to an external collection device. A sealing ring 8 for increasing airtightness is fitted on the threaded connector 7. Vibration motors 4 for accelerating separation are detachably installed at the lower left and right ends of the box body 1. A door 14 for opening and closing is provided at the rear end of the box body 1. A feed hopper 9 for introducing quartz sand is fixedly installed on the side of the upper middle part of the box body 1. A shock absorber 11 for buffering is fixedly installed on the lower middle part of the box body 1. Springs 12 for auxiliary buffering are fixedly installed around the four corners of the lower end of the box body 1. The springs 12 have dampers 13 for auxiliary rebound inside. The springs 12 and shock absorbers 11 are fixedly installed on the base 10. Mounting holes for mounting and fixing the base 10 are opened around the four corners of the upper end of the base 10.

[0023] Please see Figure 3 As shown in the figure, in this embodiment, the filter assembly 2 includes a first filter frame 201, a second filter frame 202, and a third filter frame 203. The first filter frame 201, the second filter frame 202, and the third filter frame 203 are evenly distributed from top to bottom. The first filter frame 201, the second filter frame 202, and the third filter frame 203 are all stepped structures. The first filter frame 201 has first filter holes linearly distributed, the second filter frame 202 has second filter holes linearly distributed, and the third filter frame 203 has filter holes linearly distributed. It has a third filter hole, and the pore size of the first, second and third filter holes decreases step by step. It adopts a three-stage stepped filter frame (first filter frame 201, second filter frame 202, third filter frame 203). The pore size decreases step by step, which can accurately classify quartz sand of different particle sizes. The target particle size capture rate is greatly improved compared with traditional single-stage screening. The stepped structure allows the quartz sand to slide naturally under the action of gravity, reducing the risk of accumulation and blockage. At the same time, it is combined with a vibration motor 4 (selectable frequency 10-30Hz) to enhance the fluidity.

[0024] Please see Figures 4-5In this embodiment, the self-cleaning component 3 includes a nozzle 301, a guide pipe 302, a connecting pipe 303, and a second air pressure controller 304. The nozzle 301 is located on the upper left and right sides of the filter component 2. The number and position of the nozzles 301 are matched with the structure of the filter component 2. The nozzles 301 in the same column are fixedly connected and interconnected by the guide pipe 302. The guide pipes 302 are fixedly connected and interconnected by the connecting pipe 303. The second air pressure controller 304 is fixedly installed in the middle of the side of the connecting pipe 303 away from the nozzle 301. The second air pressure controller 304 controls the air pressure sprayed from the nozzle 301. The self-cleaning component 3 adopts symmetrical high-pressure nozzles 301. The second air pressure controller 304 (such as SMCITV2050) realizes pulse jet, forming bidirectional airflow shear force, which can improve the shedding rate of adhering impurities. The guide pipe 302 and the connecting pipe 303 optimize the airflow distribution to ensure that the nozzle 301 covers the entire filter frame and avoids cleaning blind spots.

[0025] During operation, the process begins with feeding and preliminary screening. Quartz sand raw material enters the housing 1 through the feed hopper 9 and first falls onto the first filter frame 201, where large particles of impurities are intercepted and qualified sand particles fall. The vibration motor 4 (optional model: VIBCO VS-250) provides low-frequency vibration to promote the flow of sand particles.

[0026] Then, the sand particles are separated step by step. The sand particles enter the second filter frame 202, the medium-sized sand particles are intercepted and sucked out through the corresponding feed pipe 5. Then the remaining sand particles enter the third filter frame 203, and finally the fine sand is collected. The ultrafine powder can be recovered by adding a cyclone separator.

[0027] Next is the implementation of the dynamic anti-clogging mechanism and clogging monitoring: an optional differential pressure sensor (such as Siemens 7MF4433) monitors the pressure difference on both sides of the filter frame. When a certain pressure value is reached, the self-cleaning operation is triggered to perform pulse cleaning: the nozzle 301 sprays compressed air, and with the flow channel optimization of the guide tube 302, the airflow is ensured to cover the entire filter surface.

[0028] Finally, in the discharge and stabilization control stage, the first air pressure controller 6 of each level of the guide pipe 5 adjusts the negative pressure intensity to avoid over-suction or blockage, and the sealing ring 8 (made of fluororubber) ensures airtightness and prevents dust leakage.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
