Description

Technical Field

[0001] The present application relates to the technical field of drying and crushing equipment, and in particular to a disc nest mill. Background Art

[0002] Disc Nest Mill is a new type of high-efficiency material processing equipment. Through the high-speed rotating grinding tool and the special internal structure design, the material is subjected to strong shear and impact forces inside the Disc Nest Mill, so that it is quickly crushed into particles of the required size, achieving efficient crushing and deagglomeration of the material.

[0003] When grinding and crushing materials, the materials are placed in the feed port of the disc mill, and the disc mill is started. The discs in the disc mill rotate at high speed to grind the added materials. After the grinding is completed, the processed materials are discharged from the discharge port. The discs are usually set to metal materials. During grinding, the materials and discs produce high-speed collision and friction, which can easily cause the discs to wear, drop metal powder, and mix with the materials, resulting in reduced material purity, thereby affecting the grinding quality of the materials. Utility Model Content

[0004] In order to improve the grinding quality of materials, the present application provides a disc nest mill.

[0005] The present application provides a disc nest grinding mill adopting the following technical solution:

[0006] A disc nest mill comprises a machine base, a disc nest mill body fixedly arranged on the machine base, and a drive motor;

[0007] The disc nest mill body includes a support seat, a shell, a main shaft, a disc assembly and a gear plate assembly; the support seat is fixedly arranged on the top wall of the machine base, the shell is fixedly arranged on the top wall of the support seat, the main shaft is located in the shell, the inner cavity of the support seat is provided with a bearing seat, the bearing seat is fixedly connected to the top wall of the machine base, one end of the main shaft passes through the support seat and the bearing seat, the main shaft passes through one end of the bearing seat and extends into the inner cavity of the machine base, and the main shaft is rotatably connected to the bearing seat; the drive motor is used to drive the main shaft to rotate; the axis of the main shaft coincides with the central axis of the bearing seat, the shell and the support seat;

[0008] The disc assembly is located in the inner cavity of the housing and is coaxially sleeved on the side wall of the main shaft; the tooth plate assembly is fixedly arranged on the circumferential inner wall of the housing; a protective plate is provided on the disc assembly; an abrasive cavity for grinding materials is formed between the disc assembly and the tooth plate assembly;

[0009] The bottom end and the top end of the shell are respectively provided with a feeding bin and a discharging bin.

[0010] By adopting the above technical solution, a disc nest mill is set up, in which the material to be ground enters from the feed bin, and the driving motor drives the main shaft to rotate. The main shaft forms negative pressure during the rotation process, so that the material to be ground rises and is sucked into the casing. The material moves at high speed in the abrasive cavity and is ground between the tooth plate assembly and the disc assembly. After the material is ground to a small particle size, the processed raw material particles are discharged through the discharge bin under the action of negative pressure, which facilitates the disc nest mill to grind the material efficiently; at the same time, the protective plates provided on the disc assembly and the tooth plate assembly are convenient for avoiding wear of the disc assembly and the tooth plate assembly when the material is ground, which produces debris mixed into the material, resulting in reduced purity of the material, thereby reducing the grinding quality of the material.

[0011] In a specific possible implementation scheme, the output shaft of the drive motor extends into the inner cavity of the machine base, and a driving pulley is coaxially fixedly provided at the output end of the drive motor, and a driven pulley is coaxially fixedly provided at one end of the main shaft extending into the inner cavity of the machine base, and the driving pulley is belt-connected to the driven pulley.

[0012] By adopting the above technical solution, when grinding the material, the drive motor is started, and the output shaft of the drive motor drives the active pulley to rotate. The active pulley drives the driven pulley to rotate through the belt transmission, and the driven pulley drives the main shaft to rotate. The disc assembly set on the main shaft rotates synchronously, which facilitates the grinding of the material.

[0013] In a specific embodiment, the protection plate is configured as a ceramic sheet.

[0014] By adopting the above technical solution, the protective plate is set as a ceramic sheet. The hard and wear-resistant properties of the ceramic sheet itself can prevent the disc assembly and the tooth plate assembly from wearing during grinding, thereby preventing debris from mixing into the material and reducing the purity of the material.

[0015] In a specific embodiment, the disc assembly includes multiple groups of connecting members and multiple discs arranged on each group of connecting members;

[0016] The connecting member includes a disc connecting sleeve, a disc connecting plate and a plurality of connecting rods; the disc connecting sleeve is coaxially sleeved on the side wall of the main shaft and is fixedly connected to the main shaft; the disc connecting plates are fixedly provided at both ends of the disc connecting sleeve, and the disc connecting plates are coaxially provided with the disc connecting sleeve; the plurality of connecting rods are fixedly provided between the two disc connecting plates; the plurality of discs are clamped and fixed between the two disc connecting plates;

[0017] A ceramic protective tube is coaxially arranged on the circumferential side wall of the disc connecting sleeve, and the ceramic disc is attached to the side wall of the disc.

[0018] By adopting the above technical solution, the disc assembly is arranged, and when the main shaft rotates, the disc connecting sleeve rotates synchronously, driving the disc connecting plates arranged at both ends of the disc connecting sleeve to rotate, and the discs fixedly engaged at both ends of the disc connecting plates rotate along with the disc connecting plates, so as to facilitate the grinding of the material; at the same time, the disc connecting plates at both ends of the disc connecting sleeve are fixedly connected by a connecting rod, so as to facilitate the stable support of the disc connecting plates and improve the rotation stability of the disc assembly; at the same time, the ceramic protective tube arranged on the circumferential side wall of the disc connecting sleeve and the ceramic sheet attached to the side wall of the disc facilitate to avoid the disc assembly from being worn during the process of grinding the material, thereby generating debris mixed into the material, reducing the purity of the material, and resulting in reduced grinding quality of the material.

[0019] In a specific possible implementation manner, a plurality of groups of disc assemblies are arranged in sequence along the axial direction of the main shaft, and two adjacent groups of disc assemblies are fixedly connected.

[0020] By adopting the above technical solution, multiple groups of discs are fixedly connected. When grinding materials, multiple groups of disc assemblies grind the materials at the same time, which increases the contact area between the materials and the discs, facilitates improving the grinding fineness of the materials, and also improves the grinding efficiency of the materials.

[0021] In a specific embodiment, the disc is provided with weight-reducing holes.

[0022] By adopting the above technical solution, the weight-reducing holes are set to reduce the weight of the disc assembly, which is convenient for reducing the load on the drive motor when the main shaft drives the disc assembly to rotate, thereby increasing the service life of the disc nest mill.

[0023] In a specific embodiment, the tooth plate assembly includes a retaining ring, which is fixedly connected to the inner wall of the housing and is coaxially arranged with the housing; the inner wall of the retaining ring is integrally provided with a plurality of grinding teeth;

[0024] The retaining ring and the grinding teeth are both made of ceramic material.

[0025] By adopting the above technical solution, a tooth plate assembly is set up. When grinding the material, the material moves under the drive of the disc assembly. When the material continuously collides with the grinding teeth during the movement, the material is crushed during the collision, thereby achieving grinding of the material.

[0026] In a specific embodiment, the feed bin is disposed in the inner cavity of the support seat, and the feed bin is communicated with the inner cavity of the shell, and the main shaft is disposed through the feed bin;

[0027] A breaking up assembly is provided in the feed bin, and the breaking up assembly includes a transmission sleeve and an impeller. The transmission sleeve is coaxially sleeved on the side wall of the main shaft located in a section of the feed bin, and the transmission sleeve is fixedly connected to the main shaft. The impeller is fixedly provided on the circumferential side wall of the transmission sleeve, and the impeller can rotate in the feed bin.

[0028] By adopting the above technical solution, when the material is ground, the material to be ground is in the feed bin, and the main shaft drives the transmission sleeve to rotate when it rotates, and the transmission sleeve drives the impeller to rotate. The impeller breaks up the material during the rotation process, and the material is driven into the abrasive chamber by the negative pressure generated by the rotation of the main shaft for grinding processing, which is convenient for improving the grinding quality of the material.

[0029] In a specific possible implementation manner, the discharge bin is fixedly arranged on the top of the shell, and the discharge bin is communicated with the inner cavity of the shell.

[0030] By adopting the above technical solution, after the material is ground into a small particle size in the grinding chamber, the material rises under the action of the rising airflow generated by the rotation of the main shaft and enters the discharge bin. The set discharge bin is convenient for collecting the ground material.

[0031] In a specific possible implementation scheme, a heat dissipation net is provided on the side wall of the support base.

[0032] By adopting the above technical solution and setting up the heat dissipation net, the heat generated inside the disc nest mill can be quickly discharged through the holes when it is running for a long time, effectively preventing the performance degradation or damage of the equipment due to heat accumulation.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The ceramic protective tube set on the circumferential side wall of the disc connecting sleeve and the ceramic sheet attached to the side wall of the disc are convenient for preventing the disc assembly from wearing out during the grinding process, thereby generating debris mixed into the material, reducing the purity of the material and resulting in reduced grinding quality of the material.

[0035] 2. The breaking up component is set up, and the impeller rotates in the feed bin. The impeller breaks up the material during the rotation process. The material is driven into the abrasive chamber by the negative pressure generated by the rotation of the main shaft for grinding, which is convenient for improving the grinding quality of the material.
