Description

Technical Field

[0001] This utility model belongs to the technical field of whitening agent production equipment, and in particular relates to a crystal fine grinding device for whitening agent production. Background Technology

[0002] In the production process of whitening agents, fine grinding of crystals is one of the most important steps. Its purpose is to grind the synthesized whitening agent crystals to a fine particle size that meets the production requirements, so as to ensure the dispersibility and performance of the whitening agent in subsequent applications. A Chinese patent application with publication number CN223337387U discloses a crystal fine grinding device for the production of whitening agents, including a main body, a sealing treatment mechanism, and a multi-stage fine grinding mechanism. The sealing treatment mechanism includes a crushing roller, a processing box, a crushing motor, a dispensing box, and a dust splash prevention component. The dust splash prevention component includes a feed inlet, a sealing plate, a magnetic strip, and a handle. This utility model can improve the efficiency and effect of the fine grinding process by pre-crushing larger crystals to a smaller, more manageable size. In addition, this device can also effectively prevent dust splashing and reduce pollution in the working environment. While this patent effectively prevents dust splashing, it still suffers from the drawback of lacking an efficient sieving structure that works in synergy with the grinding process. Specifically, the patent cannot dynamically intervene in the grinding process. During the grinding process, the particle size of the whitening agent crystals exhibits significant inhomogeneity. Some particles may have reached the target particle size, while others remain at a larger size. In existing devices, the large particles that do not meet the target size will continuously circulate in the grinding chamber along with the smaller particles that have met the target size, or directly enter subsequent processes. If they circulate continuously, the smaller particles that have met the target size will have their crystal structure destroyed due to over-grinding, affecting the chemical properties of the whitening agent. If they directly enter subsequent processes, the large particles that do not meet the target size will reduce the uniformity of the product, resulting in unstable whitening effects during application and seriously affecting the production quality of the whitening agent. To address these issues, we provide a crystal fine grinding apparatus for the production of whitening agents. Utility Model Content

[0003] The purpose of this invention is to provide a crystal fine grinding device for the production of whitening agents. By combining the grinding component and the sieving component, it solves the problem that the existing crystal fine grinding devices for the production of whitening agents lack an efficient sieving structure that is coordinated with the grinding process, and thus cannot achieve dynamic intervention in the grinding process.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0005] This utility model relates to a crystal fine grinding device for the production of whitening agents, comprising a shell, a grinding assembly at the top of the inner cavity of the shell, a sieving assembly at the bottom of the inner cavity of the shell, and a receiving assembly at the bottom of the shell. The sieving assembly includes a connecting plate, one side of which is fixedly connected to the inner wall of the shell, and a sieving cylinder is fixedly connected between the connecting plates. A fixing plate is fixedly connected to the side of the sieving cylinder, and a movable rod is connected through the surface of the fixing plate. A spring is sleeved on the top of the surface of the movable rod, and a sieving disc is fixedly connected to the bottom of the movable rod. A vibration motor is provided on one side of the bottom of the sieving disc, and the top of the sieving disc is movably connected to the annular groove inner cavity at the bottom of the sieving cylinder.

[0006] The present invention is further configured such that the grinding assembly includes a motor housing, the bottom of which is fixedly connected to the top of the outer shell, a reduction motor is provided in the inner cavity of the motor housing, a rotating rod is fixedly connected to the output end of the reduction motor, a crushing wheel is fixedly connected to the surface of the rotating rod, a feed shell is fixedly connected to the top of the inner cavity of the outer shell, a crushing blade is fixedly connected to the inner wall of the feed shell, a grinding cam is fixedly connected to the bottom of the rotating rod, and a grinding disc is provided in the inner cavity of the outer shell and outside the grinding cam. When the reduction motor is turned on, the output end of the reduction motor drives the rotating rod to rotate, and the rotating rod drives the crushing wheel on its surface and the grinding cam at its bottom to rotate. The rotating crushing wheel and crushing blade crush the whitening agent crystals, and the crushed whitening agent crystals fall into the gap between the grinding cam and the grinding disc. The rotating grinding cam finely grinds the whitening agent crystals.

[0007] The present invention is further configured such that the receiving assembly includes an electric push rod, which is connected through to the bottom of the inner cavity of the outer shell. The telescopic shaft of the electric push rod is fixedly connected to a lifting seat, and the inner cavity of the lifting seat is movably connected to a receiving cylinder. When the electric push rod is turned on, the telescopic shaft of the electric push rod drives the lifting seat to move down to an appropriate position, and then the receiving cylinder in the inner cavity of the lifting seat is taken out for unloading, which is convenient and quick.

[0008] The present invention is further configured such that a feed inlet is provided at the top of the outer shell, and a protective cover is provided at the top of the outer shell and outside the feed inlet. Two feed inlets are provided at the top of the outer shell, and a protective cover is provided at the edge of the feed inlet to prevent material from spilling, so as to facilitate the quick addition of material to the inner cavity of the outer shell.

[0009] The present invention is further configured such that an anti-spillage disc is fixedly connected to the bottom of the inner cavity of the outer shell. The anti-spillage disc is located above the receiving cylinder. The anti-spillage disc, with its flared upper part and constricted lower part, can efficiently receive the material falling after being screened by the screening disc and accurately and quickly guide the material into the inner cavity of the receiving cylinder without spillage.

[0010] The present invention is further configured such that a limiting rod is fixedly connected to one side of the top of the lifting seat, the top of the limiting rod penetrates into the inner cavity of the outer shell, and the limiting rod moves in the inner cavity of the limiting hole at the bottom of the outer shell as the lifting seat moves. The limiting effect of the limiting rod can greatly improve the movement stability of the lifting seat.

[0011] The present invention is further configured such that a support base is fixedly connected to the bottom of the outer shell, and a load-bearing frame is provided at the bottom of the inner cavity of the support base. The top of the load-bearing frame contacts the bottom of the lifting seat. The support base can provide stable support for the bottom of the outer shell, and the load-bearing frame in the inner cavity of the support base can support the bottom of the lifting seat, thereby improving the stability of the lifting seat and reducing the driving pressure of the electric push rod.

[0012] The present invention is further configured such that a connecting cylinder is fixedly connected to the top of the screening cylinder, and the top of the connecting cylinder is fixedly connected to the bottom of the grinding disc. The connecting cylinder wraps the gap between the screening cylinder and the grinding disc, providing a safe path for the material to fall.

[0013] The present invention has the following beneficial effects.

[0014] 1. In this utility model, the ground crystal particles can immediately enter the screening cylinder. Driven by a vibrating motor, they are screened in real time through a high-frequency vibrating screening disc, so that the qualified particles are quickly separated into the receiving cylinder, avoiding continuous grinding with the unqualified particles. This design fundamentally eliminates the damage to the crystal structure of small particles caused by excessive grinding, ensures the stability of the chemical properties of the whitening agent, and ensures that the core quality of the product is not damaged.

[0015] 2. The screening structure of this utility model efficiently intercepts substandard large particles of material, preventing them from directly entering subsequent processes. Substandard material particles can be collected by disassembling the screening screen and put back into the grinding components for secondary fine grinding, forming a closed-loop process of "grinding, screening, and re-grinding". This process not only ensures the high consistency of particle size in the final product and improves product uniformity, but also avoids the problem of unstable whitening effect caused by the presence of large particles.

The screening component 3 includes a connecting plate 301, one side of the connecting plate 301 is fixedly connected to the inner wall of the shell 1, a screening cylinder 302 is fixedly connected between the connecting plates 301, a fixing plate 303 is fixedly connected to the side of the screening cylinder 302, a movable rod 304 is connected through the surface of the fixing plate 303, a spring 305 is sleeved on the top of the surface of the movable rod 304, a screening disc 306 is fixedly connected to the bottom of the movable rod 304, a vibration motor 307 is provided on one side of the bottom of the screening disc 306, and the top of the screening disc 306 is movably connected to the inner cavity of the annular groove at the bottom of the screening cylinder 302.

[0025] Specifically: When the vibration motor 307 is turned on, it generates high-frequency vibration. Since the screening disc 306 is movably connected to the screening cylinder 302 through the spring 305 and the movable rod 304, the vibration motor 307 can drive the screening disc 306 to vibrate. After the material is crushed and finely ground, it falls into the inner cavity of the screening cylinder 302 and is screened and filtered by the high-frequency vibrating screening disc 306. The material that meets the particle size requirements falls into the receiving component 4. Finally, the cover plate at the bottom of one side of the outer shell 1 is opened, and the screening screen at the bottom of the screening disc 306 is removed, so that the material that does not meet the particle size requirements falls into the receiving component 4 and is put back into the grinding component 2 for further fine grinding.

[0026] The grinding assembly 2 includes a motor housing 201, the bottom of which is fixedly connected to the top of the outer shell 1. A geared motor 202 is installed inside the motor housing 201. A rotating rod 203 is fixedly connected to the output end of the geared motor 202. A crushing wheel 204 is fixedly connected to the surface of the rotating rod 203. A feed shell 205 is fixedly connected to the top of the inner cavity of the outer shell 1. A crushing blade 206 is fixedly connected to the inner wall of the feed shell 205. A grinding cam 207 is fixedly connected to the bottom of the rotating rod 203. A grinding disc 208 is installed inside the outer shell 1 and outside the grinding cam 207. The receiving assembly 4 includes an electric push rod 401, which penetrates the bottom of the inner cavity of the outer shell 1. The telescopic shaft of the electric push rod 401 is fixedly connected to the lifting seat 402. The inner cavity of the lifting seat 402 is movably connected to the receiving cylinder 403. The top of the outer shell 1 is provided with a feed inlet. The top of the outer shell 1 and the outer side of the feed inlet are provided with a protective cover. The bottom of the inner cavity of the outer shell 1 is fixedly connected to the anti-splash plate 5. The anti-splash plate 5 is located above the receiving cylinder 403. A limit rod is fixedly connected to one side of the top of the lifting seat 402. The top of the limit rod extends through the inner cavity of the outer shell 1. A support seat 6 is fixedly connected to the bottom of the outer shell 1. A load-bearing frame 7 is provided at the bottom of the inner cavity of the support seat 6. A connecting cylinder is fixedly connected to the top of the screening cylinder 302. The top of the connecting cylinder is fixedly connected to the bottom of the grinding disc 208.

[0027] Specifically: The geared motor 202 is turned on, and its output drives the rotating rod 203 to rotate. The rotating rod 203 drives the crushing wheel 204 on its surface and the grinding cam 207 at its bottom to rotate. The rotating crushing wheel 204 and crushing blade 206 crush the whitening agent crystals. The crushed whitening agent crystals fall into the gap between the grinding cam 207 and the grinding disc 208. The rotating grinding cam 207 finely grinds the whitening agent crystals. The electric push rod 401 is turned on, and its telescopic shaft drives the lifting seat 402 to move down to a suitable position. The receiving cylinder 403 inside the lifting seat 402 is then removed for unloading, which is convenient and quick. Two feed inlets are opened on the top of the outer shell 1, and protective covers are set at the edges of the feed inlets to prevent material spillage, facilitating rapid feeding. Material is added to the inner cavity of the outer shell 1. The spill-proof disc 5, with its flared upper part and constricted lower part, can efficiently receive the material falling after being screened by the screening disc 306, and accurately and quickly guide the material into the inner cavity of the receiving cylinder 403 without spillage. The limiting rod moves with the lifting seat 402 and moves in the limiting hole at the bottom of the outer shell 1. The limiting action of the limiting rod can greatly improve the movement stability of the lifting seat 402. The support seat 6 can stably support the bottom of the outer shell 1, and the load-bearing frame 7 in the inner cavity of the support seat 6 can support the bottom of the lifting seat 402, improving the stability of the lifting seat 402 while reducing the driving pressure of the electric push rod 401. The connecting cylinder wraps the gap between the screening cylinder 302 and the grinding disc 208, providing a safe path for the material to fall.

[0028] The working principle of this utility model is as follows: First, the fine grinding device is connected to the power supply, and the reduction motor 202 is turned on. The output end of the reduction motor 202 drives the rotating rod 203 to rotate. The rotating rod 203 drives the crushing wheel 204 on its surface and the grinding cam 207 at the bottom to rotate. The whitening agent crystals are fed into the inner cavity of the outer shell 1 through the feed port. After the whitening agent crystals fall into the feed shell 205, the rotating crushing wheel 204 and crushing blade 206 crush the whitening agent crystals. When the crushed whitening agent crystals fall into the gap between the grinding cam 207 and the grinding disc 208, the rotating grinding cam 207 finely grinds the whitening agent crystals. The finely ground whitening agent crystal particles fall into the sieve. After entering the inner cavity of the cylinder 302, the vibration motor 307 is turned on. The vibration motor 307 generates high-frequency vibration. Since the screening disc 306 is movably connected to the screening cylinder 302 through the spring 305 and the movable rod 304, the vibration motor 307 can drive the screening disc 306 to vibrate. After the material is crushed and finely ground, it falls into the inner cavity of the screening cylinder 302 and is screened and filtered by the high-frequency vibrating screening disc 306. The material that meets the particle size requirements falls into the receiving cylinder 403. Finally, the cover plate at the bottom of one side of the outer shell 1 is opened, and the screening screen at the bottom of the screening disc 306 is removed, so that the material that does not meet the particle size requirements falls into the receiving cylinder 403 and is put back into the grinding assembly 2 for further fine grinding.
