Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a quartz sand screening device. Background Technology

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral composed of silicon dioxide. Its unique tetrahedral crystal structure endows it with properties such as high temperature resistance, corrosion resistance, and high insulation. This material is a core raw material for glass manufacturing. Quartz sand screening equipment is a device that separates quartz sand particles of different sizes through mechanical or airflow action. Its core function is to improve the purity and particle size uniformity of the sand. Common equipment includes vibrating screens, drum screens, airflow separators, and multi-layer flat screens. Taking a vibrating screen as an example, it uses a motor to drive an eccentric block to generate high-frequency vibration, causing the quartz sand to jump on the screen surface. Fine particles fall through the screen holes, while coarse particles move along the screen surface to the discharge port.

[0003] Chinese patent discloses a quartz sand screening device (authorization announcement number CN216150323U). This patented technology includes a device base, a device fixing frame fixedly connected to one end of the base, a frame baffle fixedly connected to one end of the fixing frame, a lateral buffer at one end of the frame baffle, a vibrating screening chamber at one end of the lateral buffer, a screening frame front plate at one end of the vibrating screening chamber, a front plate rotating shaft at the lower end of the screening frame front plate, a screening frame at one end of the front plate rotating shaft, a screening bottom screen at one end of the screening frame, and a front plate buckle rotatably connected to the upper end of the screening frame front plate. The advantages are: after screening, the screening frame can be pulled out using the screening frame handle, and the front plate buckle can be removed from the screening frame. The front plate rotating shaft allows for easy rotation of the screening frame front plate, facilitating the emptying of the quartz sand inside the screening frame, making it convenient to use.

[0004] However, this patent still has shortcomings. While the patented technology effectively screens quartz sand, it requires stopping the machine to store and retrieve the quartz sand during the screening process, which reduces the efficiency of quartz sand screening and processing. Furthermore, the screen may become clogged during the quartz sand screening process, gradually reducing the screening efficiency. Therefore, those skilled in the art have provided a quartz sand screening device to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a quartz sand screening device, comprising a shell, a hot air blower, a filter cylinder, a rotating shaft, an assembly block, and a motor. Two sets of rotating seats are provided on the lower inner wall of the shell. A feed pipe and a discharge pipe are rotatably installed inside each rotating seat. A filter cylinder is installed between each feed pipe and discharge pipe. A mounting frame is provided inside the upper part of the shell. Equally spaced springs are provided at the lower end of the mounting frame. An assembly block is provided at the lower end of each spring. A gear ring is sleeved on the outer wall of the feed pipe. A motor is fixed inside one side of the shell, and a gear that meshes with the gear ring is provided at the motor's output end.

[0008] Furthermore, bearing brackets are provided on both sides of the lower end of the mounting bracket, and a rotating shaft is rotatably installed inside the bearing bracket, with protrusions provided on the outer wall of the rotating shaft;

[0009] Specifically, the bearing bracket provides rotational support for the shaft, enabling the shaft to drive the protrusion to rotate stably below the mounting bracket.

[0010] Furthermore, the lower end of the assembly block has a travel groove that is sleeved on the outside of the rotating shaft and the protrusion. Both ends of the lower end of the assembly block are provided with rubber blocks. The mounting bracket is embedded with equally spaced sliding sleeves. The upper end of the assembly block is provided with a guide rod located inside the spring and slidably installed inside the sliding sleeve.

[0011] Specifically, when the rotating shaft drives the protrusion to rotate, it rotates inside the assembly block through the stroke groove, and the rubber block makes a flexible contact impact on the filter cartridge, thereby causing impact vibration to the filter cartridge.

[0012] Furthermore, the inner wall of the filter cartridge is provided with two sets of equidistantly distributed buffer plates, and a travel channel is provided between the buffer plates;

[0013] Specifically, the buffer plate intercepts the flowing quartz sand. When the buffer plate rotates to a high position, the sand passes through the buffer plate via the travel channel and is continuously transported inside the filter cartridge.

[0014] Furthermore, both ends of the filter cartridge are provided with flow guides, and the opposite ends of the flow guides are respectively connected to the feed pipe and the discharge pipe;

[0015] Specifically, the flow guide hood guides the flow of quartz sand inside both ends of the filter cartridge, facilitating the entry and exit of quartz sand through the feed pipe and discharge pipe.

[0016] Furthermore, both the feed pipe and the outer wall of the rotating shaft are fitted with synchronous pulleys, and the outer walls of the synchronous pulleys are fitted with belts.

[0017] Specifically, when the feed pipe rotates, it drives the synchronous pulley to rotate, which in turn drives the synchronous pulley on the outer wall of the shaft to rotate through the belt linkage, thereby driving the shaft to rotate.

[0018] Furthermore, a material box is provided at one end of the outer shell, and a guide pipe with one end suspended inside the feed pipe is connected to the lower end of the material box;

[0019] Specifically, the unscreened quartz sand is pre-stored in a hopper and then transported to the inside of the screen cylinder through a guide pipe.

[0020] Furthermore, hot air blowers are provided at both ends of the outer shell, and airflow hoods connected to the hot air blowers are provided on both sides of the filter cartridge;

[0021] Specifically, the hot air blower delivers hot air through the air hood to the filter cartridge, and then through the pores of the filter cartridge to the quartz sand, thus drying the potentially damp quartz sand.

[0022] 2. Beneficial effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] This invention features an inclined filter cylinder inside the outer casing. During use, the filter cylinder rotates, increasing the fluidity of the quartz sand fed into it and reducing clogging of the filter components. Both ends of the filter cylinder are open, allowing for continuous feeding and unloading. Small-sized quartz sand is output through the gaps in the filter cylinder, while larger-sized quartz sand is conveyed through a discharge pipe positioned low on the filter cylinder, achieving efficient quartz sand screening. During the conveying process, the filter cylinder experiences continuous vibration, preventing clogging of the filter components.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figure 1-6As shown, this embodiment is a quartz sand screening device, including a shell 1, a hot air blower 2, a filter cartridge 5, a rotating shaft 7, an assembly block 8, and a motor 10. The lower inner wall of the shell 1 is provided with two sets of rotating seats 4. The feed pipe 16 and the discharge pipe 15 are rotatably installed inside the rotating seats 4 respectively. The filter cartridge 5 is provided between the feed pipe 16 and the discharge pipe 15. The upper inner wall of the shell 1 is provided with a mounting frame 9. The lower end of the mounting frame 9 is provided with equidistantly distributed springs 24. The lower end of each spring 24 is provided with an assembly block 8. The outer wall of the feed pipe 16 is sleeved with a gear ring 26. The motor 10 is fixed inside one side of the shell 1. The output end of the motor 10 is provided with a gear 27 that meshes with the gear ring 26.

[0041] Bearing brackets 17 are provided on both sides of the lower end of the mounting frame 9. A rotating shaft 7 is rotatably installed inside the bearing bracket 17. A protrusion 20 is provided on the outer wall of the rotating shaft 7.

[0042] The lower end of the assembly block 8 has a travel groove 18 that is sleeved on the outside of the rotating shaft 7 and the protrusion 20. Both ends of the lower end of the assembly block 8 are provided with rubber blocks 19. The mounting bracket 9 is embedded with equally spaced sliding sleeves 23. The upper end of the assembly block 8 is provided with guide rods 22 located inside the spring 24 and slidably installed inside the sliding sleeves 23.

[0043] The inner wall of the filter cartridge 5 is provided with two sets of equidistantly distributed buffer plates 13, and a travel channel 14 is provided between the buffer plates 13;

[0044] Both ends of the filter cartridge 5 are provided with flow guide shrouds 6, and the opposite ends of the flow guide shrouds 6 are respectively connected to the feed pipe 16 and the discharge pipe 15.

[0045] Both the feed pipe 16 and the outer wall of the rotating shaft 7 are fitted with synchronous pulleys 21, and the outer wall of the synchronous pulleys 21 is fitted with belts 25.

[0046] The outer shell 1 is provided with a material box 3 at one end, and a guide pipe 11 with one end suspended inside the feed pipe 16 is connected to the lower end of the material box 3.

[0047] Hot air blowers 2 are provided at both ends of the outer shell 1, and airflow hoods 12 connected to the hot air blowers 2 are provided on both sides of the filter cartridge 5.

[0048] In this embodiment, the quartz sand to be screened is poured into the material box 3 and continuously conveyed to the feed pipe 16 through the guide pipe 11. The motor 10 is started to drive the gear 27 to rotate, which drives the feed pipe 16 and the filter cylinder 5 that mesh with the gear ring 26 to rotate at a uniform speed. The synchronous wheel 21 and the belt 25 are linked to make the rotating shaft 7 rotate synchronously. The protrusion 20 on the outer wall of the rotating shaft 7 moves periodically in the stroke groove 18 at the bottom of the assembly block 8. When the protrusion 20 presses the inner wall of the upper end of the assembly block 8, it presses the spring 24. When the protrusion 20 passes through the assembly block 8, the assembly block 8, under the action of the elastic force of the spring 24, drives the rubber block 19 to apply frequency impact vibration to the filter cylinder 5.

[0049] Quartz sand moves towards the discharge pipe 15 along the inclined angle as the filter cylinder 5 rotates. Fine particles fall into the lower end through the pores of the filter cylinder 5, while coarse particles are discharged from the discharge pipe 15 as the filter cylinder 5 rotates to the lower end. The buffer plate 13 forms a stepped flow guiding structure on the inner wall of the filter cylinder 5. When the filter cylinder 5 drives the buffer plate 13 to rotate to a high position, the quartz sand flows faster through the stroke channel 14 to avoid accumulation. When it rotates to a low position, the buffer plate 13 intercepts the sand flow and prolongs the screening contact time.

[0050] Hot air blower 2 delivers high-temperature airflow through airflow cover 12 and blows it into filter cartridge 5. The airflow penetrates the quartz sand layer to achieve a dual function: first, to evaporate moisture and prevent damp particles from sticking to the filter pores; second, to further separate the fine powder impurities wrapped on the surface of the sand particles through gas-solid two-phase flow disturbance. The vibration system continuously impacts the filter cartridge 5, causing the particles stuck in the pores to fall off and reducing the screen clogging rate.

[0051] Coarse sand is discharged directly into an external collection container through discharge pipe 15, while fine sand is collected at the bottom outlet through the guide surface below filter cylinder 5. The entire process does not require stopping the machine for cleaning. The centrifugal force generated by the rotation of filter cylinder 5 makes the sand particles adhere tightly to the cylinder wall, enhancing the probability of fine particles passing through the screen. The amplitude generated by the impact of the protrusions 20 on filter cylinder 5 breaks the adsorption force between particles, preventing clogging. The airflow shear force and thermal expansion effect work together to remove impurities, while reducing the surface energy of the sand particles and inhibiting agglomeration.

[0052] Traditional vibrating screens require shutdown for screen cleaning or batch replacement, resulting in a relatively low percentage of effective operating time. This device, through the open design of the rotating filter cylinder 5 at both ends, achieves continuous feeding, screening, and discharging throughout the entire process. The tilt angle of the filter cylinder 5 is linked to the rotation speed, dynamically optimizing the material residence time according to the characteristics of the sand. It integrates a triple solution of mechanical vibration, airflow disturbance, and structural optimization. Combined with the buffer of rubber blocks 19, it forms high-frequency micro-amplitude vibration, effectively removing stuck particles. Hot air is output from the airflow hood 12, forming a swirling field to peel off attached impurities. The filter cylinder 5 adopts a trapezoidal cross-section pore design, wider at the top and narrower at the bottom, which, combined with centrifugal force, achieves self-unblocking of pores, reducing the clogging rate compared to flat screens.

[0053] This device uses a hot air system to precisely control the temperature, which can dry sand with initial moisture content. The synchronous pulley 21 and belt 25 drive to avoid the use of additional electrical equipment, reducing production costs. The semi-enclosed shell 1 integrates a pulse dust removal module, which reduces the dust emission rate.
