Description

Technical Field

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

[0002] Quartz sand is highly wear-resistant and corrosion-resistant, and is widely used in glass, casting, water treatment and other fields. Based on particle size, it is classified into coarse sand, medium sand, and fine sand. Quartz sand is crushed into small particles by a crushing device to facilitate subsequent processing.

[0003] Chinese patent discloses a quartz sand crushing device (authorization announcement number CN217368561U). This patented technology includes a crushing box, a crushing impeller assembly, a cleaner, a material distribution seat, a screening component, and a storage container. The crushing impeller assembly is mounted on the crushing box, the cleaner is mounted on the crushing box, the material distribution seat is located inside the crushing box and below the crushing impeller assembly, the screening component is located inside the crushing box, and the storage container is located inside the crushing box. The screening component includes a screen, a guardrail, a mounting base, and an electric push rod. The screen is hinged inside the crushing box, the guardrail is mounted on the screen, the mounting base is mounted on the crushing box, and the electric push rod is hinged between the screen and the mounting base. This utility model relates to the field of quartz sand crushing device design, specifically a quartz sand crushing device.

[0004] However, this patent still has shortcomings. While it offers the advantage of screening crushed quartz sand, the quartz sand is crushed by compression within the gap between two sets of crushing rollers in the quartz sand crushing device. The guide plate located at the upper end of the crushing rollers serves a guiding function. During operation, quartz sand may enter the gap between the lower end of the guide plate and the crushing rollers. This accumulation of quartz sand causes continuous wear on the lower end of the guide plate, resulting in metal fragments falling and contaminating the quartz sand. Furthermore, the small gap in the guide plate can lead to material conveying blockage. Therefore, those skilled in the art have provided a quartz sand crushing device with protective features 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 crushing device with protective functions, comprising,

[0008] The crushing structure includes a crushing box, crushing motors symmetrically distributed at the front end of the crushing box, and crushing rollers located at the output end of the crushing motors and rotatably installed inside the crushing box.

[0009] The protective structure includes guide plates located on both sides above the crushing roller, mounting shafts located at both ends of the guide plates and rotatably installed inside the crushing box, a support ring located at one end of the mounting shaft and outside the crushing box, a torsion spring sleeved on the outside of the mounting shaft and connected at both ends to the support ring and the outer wall of the crushing box respectively, a force-bearing plate located on the outer wall of the mounting shaft, and a rotating rod located on the outer wall of the crushing roller with a misaligned rotation path.

[0010] as well as;

[0011] The feeding structure includes a material box located at the top of the crushing box, a feeding motor located at the front end of the material box, a rotating shaft located at the output end of the feeding motor and rotatably installed inside the material box, and rotating plates arranged in a ring array on the outer wall of the rotating shaft.

[0012] Furthermore, a discharge area is provided at the lower end of the crushing box, and a guide frame located below the crushing roller is provided inside the lower end of the crushing box. A discharge port located inside the lower end of the guide frame is provided on one side.

[0013] Specifically, the crushed quartz sand is transported to the discharge port. During the transport process, the quartz sand is gathered to the discharge port through the guide frame. The discharge port located on one side of the lower end of the crushing box is convenient for use with the screening component. It is located at the higher horizontal position of the screening component for gravity flow screening.

[0014] Furthermore, baffles are provided on both sides of the inner wall of the crushing box, located on the side above the guide plate;

[0015] Specifically, the baffle shields the rotating part of the mounting shaft to prevent quartz sand raw material from entering the rotating mounting part between the mounting shaft and the crushing box.

[0016] Furthermore, one end of the rotating rod is rotatably mounted with equally spaced ball bearings, one end of the mounting shaft is provided with a connecting plate that is away from the force plate, and one end of the crushing box is provided with a stop bar located on the upper and lower sides of the connecting plate.

[0017] Specifically, when the mounting shaft rotates, it drives the connecting plate and the load-bearing plate to rotate. The connecting plate is limited by the stop bar, allowing the connecting plate to rotate only between the stop bars, thus restricting the rotation path of the mounting shaft and preventing the guide plate from rotating excessively.

[0018] Furthermore, the upper end of the material box is provided with a feeding port, and the lower end of the material box is provided with a discharge port corresponding to the rotating plate;

[0019] Specifically, the quartz sand raw material is fed into the hopper through the feed port and pre-stored inside the hopper. The rotating plate then transfers the quartz sand raw material through the discharge port into the crushing box, preventing excessive accumulation of quartz sand raw material on the upper part of the guide plate.

[0020] Furthermore, the inner wall of the material box is provided with a liner, and the upper end of the crushing box is provided with a buffer plate that is located above the guide plate and below the discharge port and is distributed in a relatively opposite manner.

[0021] Specifically, the lining plate increases the wear resistance of the inner wall of the hopper, and the buffer plate prevents the fed quartz sand raw material from falling directly onto the guide plate.

[0022] 2. Beneficial effects

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

[0024] In this invention, quartz sand raw material is conveyed to the gap between the crushing rollers via a guide plate. The crushing rollers, rotating relative to each other, crush the quartz sand raw material by squeezing and pulverizing it. The crushed quartz sand falls downwards and is discharged. During this process, due to the squeezing and splashing of the crushing rollers and the accumulation of quartz sand raw material, some quartz sand raw material enters the gap between the lower end of the guide plate and the crushing rollers. The guide plate is rotatably mounted inside the crushing chamber via a mounting shaft and is supported by a torsional spring. When the crushing rollers rotate, the linkage rotating rod passes through the force plate on the outer wall of the mounting shaft, thereby squeezing the torsional spring, causing the guide plate to... The guide plate is slightly raised, and after the rotating rod passes the force plate, it is reset by the elastic force of the torsion spring. During this process, the gap between the guide plate and the crushing roller widens. As the crushing roller rotates, the quartz sand material entering the gap between the lower end of the guide plate and the crushing roller is carried in, which prevents the quartz sand material from accumulating and continuously wearing down the lower end of the guide plate. This also improves the situation where metal fragments falling from the guide plate contaminate the quartz sand material, effectively protecting the guide plate. At the same time, the guide plate swings up and down during the quartz sand crushing process, improving the smoothness of material flow and preventing the quartz sand material from clogging.

[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

[0040] 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.

[0041] Example 1

[0042] Please see Figure 1-6 As shown, this embodiment is a quartz sand crushing device with protective function, including,

[0043] The crushing structure 100 includes a crushing box 101, a crushing motor 102 symmetrically distributed at the front end of the crushing box 101, and a crushing roller 104 located at the output end of the crushing motor 102 and rotatably installed inside the crushing box 101.

[0044] The protective structure 300 includes guide plates 301 located on both sides above the crushing roller 104, mounting shafts 302 located at both ends of the guide plates 301 and rotatably installed inside the crushing box 101, a support ring 310 located at one end of the mounting shaft 302 and outside the crushing box 101, a torsion spring 306 sleeved on the outside of the mounting shaft 302 and connected at both ends to the support ring 310 and the outer wall of the crushing box 101 respectively, a force plate 309 located on the outer wall of the mounting shaft 302, and a rotating rod 304 located on the outer wall of the crushing roller 104 with a misaligned rotation path;

[0045] The lower end of the crushing box 101 is provided with a discharge area 103, and the lower end of the crushing box 101 is provided with a guide frame 105 located below the crushing roller 104. The lower end of the guide frame 105 is provided with a discharge port 106 located on one side of the lower end of the crushing box 101.

[0046] Both sides of the inner wall of the crushing box 101 are provided with baffles 303 located on the side above the guide plate 301;

[0047] One end of the rotating rod 304 has equidistantly distributed ball bearings 305 rotatably mounted on its outer wall. One end of the mounting shaft 302 is provided with a connecting plate 308 that is away from the force plate 309. One end of the crushing box 101 is provided with a stop bar 307 located on the upper and lower sides of the connecting plate 308.

[0048] The protective structure 300 is used;

[0049] Through the synergistic effect of the dynamic protective structure 300 and the feeding system, the problems of wear and contamination of the guide plate 301, material blockage, and uneven feeding in traditional quartz sand crushing equipment are completely solved. After the raw material enters the crushing box 101, the protective structure 300 starts to work. The guide plate 301 is rotatably installed inside both sides of the crushing box 101 via the mounting shaft 302. The initial position forms a small angle with the gap between the crushing rollers 104. The raw material slides along the surface of the guide plate 301 into the gap between the two sets of relatively rotating crushing rollers 104 for crushing. When the crushing rollers 104 rotate, the rotating rod 304 on its outer wall periodically contacts the force plate 309 on the outer side of the guide plate 301, forcing the mounting plate 301 to rotate. Shaft 302 drives guide plate 301 to rise against the elastic force of torsion spring 306, causing the gap between guide plate 301 and crushing roller 104 to widen instantaneously. After rotating rod 304 disengages, torsion spring 306 drives guide plate 301 to reset. This dynamic oscillation mechanism produces a triple effect: First, when the gap widens, the quartz sand stuck in the gap is thrown out by the rotational force of crushing roller 104, avoiding continuous squeezing that causes metal fragments to fall off. Second, the micro-vibration of guide plate 301 breaks the material accumulation bridging. Combined with the design of baffle 303 on the inner wall of crushing box 101, it completely prevents raw materials from entering the rotating part of mounting shaft 302. Third, it prevents the mechanism from jamming, improves the flowability of raw materials, and avoids material blockage.

[0050] The crushed quartz sand is collected by the guide frame 105 and discharged to the outlet 106, where it flows by gravity. During operation, the connecting plate 308 at one end of the mounting shaft 302 is limited by the stop bar 307 to ensure that the swing amplitude of the guide plate 301 is controllable. This avoids structural fatigue caused by excessive rotation and ensures that the guide plate 301 always covers the effective working area of ​​the crushing roller 104. The protective structure 300 reduces the wear rate of the guide plate 301, reduces the risk of metal contamination, and extends the equipment maintenance cycle through dynamic gap adjustment and mechanical cleaning mechanism.

[0051] Example 2

[0052] Please see Figure 1-6 As shown, and;

[0053] The feeding structure 200 includes a material box 205 located at the upper end of the crushing box 101, a feeding motor 201 located at the front end of the material box 205, a rotating shaft 206 located at the output end of the feeding motor 201 and rotatably installed inside the material box 205, and rotating plates 204 arranged in a ring array on the outer wall of the rotating shaft 206.

[0054] The upper end of the material box 205 is provided with a feeding port 207, and the lower end of the material box 205 is provided with a discharge port 203 corresponding to the rotating plate 204.

[0055] The inner wall of the material box 205 is provided with a liner 202, and the upper end of the crushing box 101 is provided with a buffer plate 107 that is located above the guide plate 301 and below the discharge port 203 and is relatively distributed.

[0056] Use of feeding structure 200;

[0057] When the equipment is in use, it first achieves uniform feeding through the feeding structure 200. Quartz sand raw material is put in through the feeding port 207 at the top of the material box 205. The feeding motor 201 drives the rotating shaft 206 to rotate the rotating plate 204 distributed in a ring array, periodically pushing the raw material so that it falls into the crushing box 101 through the discharge port 203 at a controllable rate. During this process, the lining plate 202 on the inner wall of the material box 205 effectively resists the impact and wear of the raw material. The buffer plate 107 below the discharge port 203 further disperses the falling impact force to avoid the raw material directly hitting the guide plate 301 and causing local accumulation. The linkage design between the rotating plate 204 and the discharge port 203 makes the feeding rate match the processing capacity of the crushing roller 104 in real time, preventing excessive accumulation of raw material above the guide plate 301.
