Description

TECHNICAL FIELD

[0001] The utility model relates to sand mill technical field relates to a sand mill with buffer device. BACKGROUND

[0002] In many industrial fields such as paint processing production, horizontal sand mill is widely used. The working principle of horizontal sand mill is that the pre-mixed raw materials are sent into the main machine grinding groove, the grinding groove is filled with grinding media such as glass beads, the dispersion blade rotates at high speed to give the grinding media enough kinetic energy, so that the shear force is generated by the impact of the dispersed particles, the dispersion effect is realized, and then the dispersed materials and grinding media are separated and discharged through special separation device. Compared with three-roller equipment, horizontal sand mill is simple to operate, and uniform and excellent product quality can be obtained without high professional skills, and a large amount of continuous production can be realized, which not only improves product quality, but also reduces production cost, and is suitable for dispersion of high viscosity materials, so it has important application in paint, ink, medicine, food, cosmetics and pesticide industries.

[0003] In the paint production process, the raw materials are discharged from the discharge port after being ground by the horizontal sand mill, the discharge port is communicated with the vacuum pump, and the raw materials are pumped into the paint mixing tank through the vacuum pump for recompounding, and then discharged from the paint mixing tank into the dispersion workshop for stirring, and finally the product is obtained. However, the existing horizontal sand mill has obvious problems in actual application. When the feeding of the horizontal sand mill is not continuous or the feeding amount is unstable, the discharge will also be unstable. However, the vacuum pump is continuously pumping the sand-milled raw materials, and in the case that the discharge amount of the sand mill is not continuous, the vacuum pump will pump air into the paint mixing tank, which will directly lead to inaccurate raw material ratio in the paint mixing tank, thereby affecting the quality and performance of the final product, increasing the uncertainty and defective rate in the production process, improving the production cost, and being not conducive to the efficient and stable operation of industrial production. UTILITY MODEL CONTENTS

[0004] In view of the above prior art, in order to prevent the vacuum pump from pumping air into the paint mixing tank, resulting in inaccurate raw material ratio in the paint mixing tank, the applicant designs a sand mill with buffer device.

[0005] The sand mill with buffer device provided by the application adopts the following technical scheme:

[0006] A sand mill with buffer device, comprising a horizontal sand mill and a storage tank, a feeding port is formed on the storage tank, the discharge port of the horizontal sand mill is communicated with the feeding port on the storage tank, an output port is formed on the end of the storage tank away from the feeding port, the output port of the storage tank is communicated with the vacuum pump, and the raw materials are pumped into the paint mixing tank through the vacuum pump.

[0007] By adopting the technical scheme, the storage tank builds a buffer link between the horizontal sand mill and the paint mixing tank. When the horizontal sand mill feeding is unstable, causing the output to fluctuate, the storage tank can temporarily store the material, avoiding the vacuum pump directly pumping air into the paint mixing tank, ensuring the accurate proportion of raw materials in the paint mixing tank, stabilizing the product quality, reducing the defective rate, reducing the production cost, and ensuring the efficient and stable industrial production.

[0008] Preferably, the discharge port of the horizontal sand mill is provided with a discharge pipe, and one end of the discharge pipe away from the horizontal sand mill is fixedly connected and communicated with the feed port of the storage tank.

[0009] By adopting the technical scheme, the discharge pipe provides a stable conveying path for the discharge of the horizontal sand mill, ensuring that the ground material can smoothly and efficiently enter the storage tank, reducing the risk of material leakage, and ensuring the coherence and sealing of the entire production process.

[0010] Preferably, a sealing cover is arranged on the storage tank, and the feed port of the storage tank is located on the sealing cover.

[0011] By adopting the technical scheme, the sealing cover effectively prevents dust, impurities and the like from entering the storage tank, maintaining the purity of the raw materials in the tank. In some production scenarios with extremely high requirements for the purity of raw materials, such as the pharmaceutical and food industries, the sealing cover can prevent foreign matter from mixing in, prevent the raw materials from deteriorating or being contaminated, and ensure that the quality and safety of the final product meet the standards.

[0012] Preferably, a guide plate is arranged at one end of the storage tank close to the sealing cover, and a filter screen is arranged at one end of the storage tank close to the conveying port.

[0013] By adopting the technical scheme, the guide plate can guide the material entering from the feed port to be evenly dispersed in the storage tank. The inclined design of the guide plate cooperates with the action of gravity to make the material flow naturally in the direction of the output port, improving the flowability and storage efficiency of the material. The filter screen can intercept impurities in the material, such as grinding media debris generated during the grinding process and metal particles generated by equipment wear. If these impurities enter the paint mixing tank, they will affect the performance and appearance quality of the product. The setting of the filter screen effectively improves the purity of the raw materials entering the paint mixing tank, ensuring the quality of the final product.

[0014] Preferably, one end of the storage tank close to the conveying port is conical.

[0015] By adopting the technical scheme, the conical design makes it easier for the material at the bottom of the storage tank to collect towards the output port under the action of gravity, reducing the residue of the material at the bottom of the tank, improving the discharge efficiency of the material, avoiding waste of the material, and facilitating cleaning and maintenance of the storage tank.

[0016] Preferably, a connecting pipe is arranged at the output port of the storage tank, a conveying pipe is sleeved on the connecting pipe, a clamp is arranged on the conveying pipe, and the conveying pipe is fixedly connected with the connecting pipe through the clamp.

[0017] By adopting the above technical scheme, the combination of the connecting pipe and the conveying pipe provides a reliable channel for conveying the material from the storage tank to the vacuum pump. The use of the clamp makes the connection between the connecting pipe and the conveying pipe tight and firm, preventing material leakage and air mixing, and ensuring the sealing and stability of the conveying process. This connection method is easy to install and disassemble, facilitating operation during equipment maintenance, repair or component replacement, and improving the maintainability and service life of the equipment.

[0018] Preferably, a plurality of protrusions are arranged on the surface of the guide plate.

[0019] By adopting the above technical scheme, the protrusions can effectively break the bubbles generated after the material is processed by the sand mill. When the material impacts the protrusions, the bubbles are broken by extrusion and shearing force, reducing the influence of bubbles on the quality of the material and improving the quality of the raw material, providing a better raw material basis for subsequent paint mixing and product production.

[0020] Preferably, an observation window is arranged on the tank body of the storage tank.

[0021] By adopting the above technical scheme, the observation window provides a way for the operator to intuitively understand the state of the material in the storage tank. By observing the storage capacity of the material through the observation window, the operator can timely grasp the raw material reserve situation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The storage tank builds a buffer link between the horizontal sand mill and the paint mixing tank. When the horizontal sand mill feeding is unstable, causing the discharge amount to fluctuate, the storage tank can temporarily store the material, avoiding the direct pumping of air into the paint mixing tank by the vacuum pump, ensuring accurate raw material ratio in the paint mixing tank, stabilizing product quality, reducing scrap rate, reducing production cost, and ensuring efficient and stable industrial production;

[0024] 2. The discharge pipe provides a stable conveying path for the discharge of the horizontal sand mill, ensuring that the ground material can smoothly and efficiently enter the storage tank, reducing the risk of material leakage, and ensuring the coherence and sealing of the entire production process;

[0025] 3. The protrusions can effectively break the bubbles generated after the material is processed by the sand mill. When the material impacts the protrusions, the bubbles are broken by extrusion and shearing force, reducing the influence of bubbles on the quality of the material and improving the quality of the raw material, providing a better raw material basis for subsequent paint mixing and product production.
