[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device with a feeding structure for preparing quartz sand, comprising a mounting frame, a box on the mounting frame, a feed pipe fixedly disposed inside the box, a filter plate fixedly disposed between the feed pipe and the inner wall of the box, the filter plate being inclined, a quantitative feeding mechanism disposed above the filter plate, the quantitative feeding mechanism comprising a mounting box located above the filter plate, slots symmetrically opened at the upper and lower ends of the mounting box, a rotating block fitted therewith inside the mounting box, four receiving slots opened on the rotating block, a rotating shaft fixedly disposed on the rotating block, one end of the rotating shaft being connected to the output end of a first motor, the first motor being fixed on the outer wall of the box, a vibration assembly cooperating with the filter plate at the other end of the rotating shaft, a crushing mechanism cooperating with the quantitative feeding mechanism on one side of the box, and a stirring assembly disposed inside the box.

[0006] Furthermore, the vibration assembly includes an impact block disposed at the end of the rotating shaft away from the first motor, and the filter plate is provided with an elastic wave plate that cooperates with the impact block.

[0007] Furthermore, the crushing mechanism includes a crushing device located on one side of the housing. The upper and lower ends of the crushing device are respectively provided with a first connecting pipe and a second connecting pipe communicating with the housing. The end of the first connecting pipe away from the crushing device is engaged with a filter plate.

[0008] Furthermore, the crushing equipment is mounted on the mounting frame via a fixing bracket.

[0009] Furthermore, the stirring assembly includes a second motor mounted on a fixed plate, the output end of which is connected to a rotating rod, and the rotating rod is provided with an array of multiple stirring blades.

[0012] Furthermore, a storage box is fixedly installed on the box body, and the storage box is fixedly connected to the installation box. A feed pipe communicating with the storage box is provided on one side of the box body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the mixing device with a feeding structure for preparing quartz sand is reasonable and has the following advantages:

[0014] (1) The mixing device significantly improves the accuracy of the batching ratio in the preparation of quartz sand through the innovative design of the quantitative feeding mechanism. The quantitative feeding mechanism consists of a mounting box, a rotating block and a receiving tank. The rotating block rotates periodically under the drive of a motor. Its receiving tank receives the quartz sand raw material in the storage box in sequence and releases a quantitative amount of raw material when it rotates to the bottom slot. This design realizes intermittent quantitative feeding. The volume of each receiving tank is fixed, thereby ensuring that the amount of material fed each time is highly consistent. Compared with the traditional continuous feeding method, this mechanism avoids the problem caused by uneven raw material flow rate or human error. This feature addresses the issue of imbalanced proportions, making it particularly suitable for quartz sand mixing processes with strict ratio requirements. Furthermore, the quantitative feeding mechanism effectively prevents excessive or insufficient addition of raw materials through the physical barrier effect of the rotating block. When the receiving tank is not aligned with the slot, the solid part of the rotating block will seal the feed port of the storage box, completely cutting off the flow of raw materials and eliminating accidental leakage or excessive addition of raw materials from the source. This feature not only reduces the waste of quartz sand raw materials but also reduces the risk of rework due to incorrect proportions in subsequent processes, while saving raw material costs and improving product quality stability.

[0015] (2) The device solves the common clogging and agglomeration problems in the quartz sand mixing process through the synergistic effect of the vibration component and the crushing mechanism, and significantly improves the mixing efficiency. The vibration component consists of a striking block and an elastic wave plate. When the rotating shaft drives the striking block to rotate, it periodically impacts the elastic wave plate, causing high-frequency micro-vibration of the filter plate. This vibration keeps the quartz sand particles on the surface of the filter plate in a dynamic dispersion state, effectively preventing fine particles from clogging the filter holes, and avoiding downtime caused by traditional manual unclogging. For large particles or agglomerated raw materials that fail to pass through the filter plate, the device achieves automated circulation processing by tilting the filter plate and crushing equipment. Large particles slide along the filter plate into the first connecting pipe, are crushed by the crushing equipment, and then return to the box for remixing through the second connecting pipe. This closed-loop design not only avoids manual intervention, but also ensures the uniformity of particle size of all raw materials, thereby improving the structural consistency of the final product.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0024] Example 1:

[0025] A mixing device with a feeding structure for preparing quartz sand includes a mounting frame 100, a housing 101 mounted on the mounting frame 100, a feed pipe 103 fixedly mounted inside the housing 101, a filter plate 105 fixedly mounted between the feed pipe 103 and the inner wall of the housing 101, and the filter plate 105 being inclined; a quantitative feeding mechanism is provided above the filter plate 105, the quantitative feeding mechanism including a mounting box 200 located above the filter plate 105, the mounting box 200 having symmetrically opened slots 201 at its upper and lower ends; The mounting box 200 is equipped with a rotating block 202 that fits therein. The rotating block 202 has four receiving slots 203. A rotating shaft 204 is fixed on the rotating block 202. One end of the rotating shaft 204 is connected to the output end of the first motor 205, and the first motor 205 is fixed on the outer wall of the box 101. The other end of the rotating shaft 204 is equipped with a vibration component that cooperates with the filter plate 105. A crushing mechanism that cooperates with the quantitative feeding mechanism is provided on one side of the box 101. A stirring component is provided inside the box 101.

[0026] The vibration assembly includes an impact block 206 disposed at the end of the rotating shaft 204 away from the first motor 205, and the filter plate 105 is provided with an elastic wave plate 106 that cooperates with the impact block 206.

[0027] The crushing mechanism includes a crushing device 300 located on one side of the housing 101. The crushing device 300 has a first connecting pipe 301 and a second connecting pipe 302 communicating with the housing 101 at its upper and lower ends, respectively. The end of the first connecting pipe 301 away from the crushing device 300 is engaged with the filter plate 105.

[0028] The crushing equipment 300 is mounted on the mounting frame 100 via a fixing frame 303.

[0029] The stirring assembly includes a second motor 400 mounted on a fixed plate 104. The output end of the second motor 400 is connected to a rotating rod 401, and a plurality of stirring blades 402 are arrayed on the rotating rod 401.

[0030] The fixing plate 104 is provided with a protective cover 403 for protecting the second motor 400.

[0031] Two sets of protective plates 107 are symmetrically arranged on the filter plate 105.

[0032] A storage box 102 is fixedly installed on the box body 101, and the storage box 102 is fixedly connected to the installation box 200. A feed pipe 103 communicating with the box body 101 is provided on one side of the box body 101.

[0033] Working principle: In the process of preparing quartz sand, it is necessary to mix quartz sand with other raw materials in a certain proportion to ensure the accuracy of the proportion and thus ensure the stability of product quality. During use, the storage box 102 is used to store the quartz sand raw material. The storage box 102 will send the quartz sand raw material inside into the quantitative feeding mechanism. This mechanism can avoid the over-addition or under-addition of quartz sand raw material, reduce the waste of quartz sand raw material, and ensure that the quartz sand raw material is evenly distributed when it enters the box 101, reducing the agglomeration and accumulation of quartz sand raw material, thereby improving the uniformity of mixing. The feed pipe 103 is used to transport other raw materials to facilitate mixing with the quartz sand raw material. The first motor 205 is started, which drives the rotating shaft 204 to rotate slowly, thereby driving the rotating block 202 to rotate. Since the top of the mounting box 200 is fixedly connected to the bottom of the storage box 102, and the feed inlet of the storage box 102 is aligned with the slot 201 on the mounting box 200, the quartz sand raw material output from the storage box 102 can enter the receiving slot 203 on the rotating block 202 through the slot 201. When the rotating block 202 rotates, the part of the rotating block 202 without the receiving slot 203 will block the feed inlet of the storage box 102 to prevent material from being discharged, until the next receiving slot 203 rotates, and the receiving slot 203 filled with quartz sand raw material reaches the bottom. When the groove 201 is cut, the particles fall onto the filter plate 105. The first motor 205 here can be a servo motor or a stepper motor. The filter plate 105 can filter out fine particles, allowing them to enter the housing 101. Simultaneously, the rotating block 202 rotates, driving the striking block 206 located at the end of the rotating shaft 204 to rotate. The rotating striking block 206 strikes the elastic wave sheet 106 mounted on the filter plate 105, and the vibration generated by the strike causes the filter plate 105 to vibrate slightly, thereby preventing the quartz sand raw material from being trapped when passing through the filter plate 105. At 05, the filter holes become clogged. Two sets of protective plates 107 on the filter plate 105 serve a protective function, preventing the quartz sand raw material from splashing to other places during the feeding process. While the filter plate 105 filters the quartz sand raw material, larger particles are intercepted by the filter holes. Due to the inclined design of the filter plate 105, larger or agglomerated quartz sand raw materials slide down the filter plate 105 and enter the first connecting pipe 301 through the opening in the housing 101. The material is then transported to the crusher via the first connecting pipe 301. The crushing process takes place inside the crushing equipment 300. The crushed quartz sand raw material is then transported to the housing 101 through the second connecting pipe 302. The second motor 400 drives the rotating rod 401 to rotate, thereby driving the stirring blade 402 to mix the quartz sand raw material. The stirring blade 402 is inclined, which can better promote the mixing of the quartz sand raw material in the housing 101 and increase the contact area between the quartz sand raw material and the stirring blade 402, so that the quartz sand raw material is subjected to more shearing and stirring during the mixing process, thereby improving the mixing efficiency.
