Description

Technical Field

[0001] This utility model relates to the technical field of material cylinders for dispersers, specifically a sieveable material cylinder for a sand mill dispersion mixer. Background Technology

[0002] The sand mill dispersion mixer, also known as a sand mill disperser, is commonly used in production environments and fields such as laboratories or paint processing. It integrates sand milling and dispersion functions, and achieves multi-functional operation through interchangeable grinding discs and dispersion impellers. It is suitable for the needs of nanomaterial preparation, paint dispersion, etc. It integrates sand milling, dispersion and stirring functions, and achieves multiple process switching through replaceable components (dispersion disc, sand mill disc, stirring impeller). It is suitable for laboratory to pilot-scale production needs. The material cylinder is the main part of the disperser for sand milling and stirring, providing space for the material and stirring process.

[0003] The prior art patent with publication number CN213132817U discloses a paint grinding and stirring device, including a telescopic rod and a base. The bottom of the telescopic rod is threadedly connected to the middle of the base. The top of the telescopic rod is equipped with a frequency converter, and a control panel is provided on the top side of the frequency converter. The middle of the telescopic rod is equipped with a lifting and locking handle. A frequency converter motor is fixedly connected to the top of the telescopic rod, and a stirring shaft is fixedly connected to the bottom of the frequency converter motor. A stirring cylinder is provided at the bottom of the stirring shaft.

[0004] The aforementioned disperser uses a dedicated variable frequency motor, which generates low heat and is brushless. It is equipped with a multi-diagram speed control knob for easy operation and can perform three functions: sand milling, dispersion, and stirring. It is suitable for chemical laboratories. However, the material cylinder structure is simple. When grinding materials, it cannot screen the qualified grinding particles in real time. It can only perform dispersion within the set sand milling time and observe whether the particle size meets the standard after stirring, which affects the overall sand milling and dispersion efficiency. Therefore, we propose a screenable material cylinder for a sand milling dispersion mixer. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide a sieveable material cylinder for a sand mill dispersion mixer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sieveable material cylinder for a sand mill dispersion mixer, comprising a main cylinder body, an inner cylinder frame fastened to the top of the main cylinder body, the inner cylinder frame including a top cover, a slot formed around the bottom surface of the top cover, an inclined surface circumferentially distributed on the top surface of the top cover, an inner cylinder wall fixedly connected to the bottom end of the top cover, an inner cylinder bottom plate fixed to the bottom end of the inner cylinder wall, sieve holes formed around the interior of the inner cylinder wall, a sand milling chamber provided inside the inner cylinder wall, and a collection chamber provided on the outer wall of the inner cylinder wall.

[0008] Furthermore, the collection chamber is cylindrically opened around the inner wall of the main cylinder, and the top cover is fastened to the top surface of the main cylinder through a slot.

[0009] Furthermore, the inclined surfaces are distributed in a ring along the top surface of the top cover, and the bottom edge of the top cover is integrally fixedly connected to the bottom plate of the inner cylinder through the inner cylinder wall.

[0010] Furthermore, the screening holes are opened around the inner wall of the inner cylinder, and the lower end of the inner cylinder wall is inclined.

[0011] Furthermore, the inner cylinder bottom plate is closed, and the grinding chamber is opened along the inner cylinder wall and the inner wall of the inner cylinder bottom plate.

[0012] Furthermore, the main cylinder includes an outer cylinder frame, the outer walls of which are covered with corrugated layers, a base is fixed to the bottom of the outer cylinder frame, a rubber pad is embedded in the bottom surface of the base, and a magnetic block is fixed to the center of the base.

[0013] Furthermore, the corrugated layer is distributed in a corrugated shape along the outer wall of the outer cylinder frame, and the rubber pad and magnetic block are integrally fixed to the bottom of the outer cylinder frame through the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The material cylinder consists of an outer cylinder frame and an inner cylinder wall and an inner cylinder bottom plate connected by a top cover. During the sand milling process, qualified material particles will be discharged into the collection chamber through the sieve holes arranged around the inner cylinder wall by the centrifugal force of stirring, while unqualified particles will continue to flow into the inner cylinder bottom plate through the sieve holes in the inclined state at the bottom and be sand milled during the stirring process, thus completing the integration of sand milling and sieving processes, improving efficiency and convenience.

[0016] The inner wall and bottom plate of this material cylinder are connected by a top cover to form an internal grinding chamber structure. It can be fastened to the top surface of the outer cylinder frame through the slot at the bottom of the top cover, which is convenient for disassembly, installation and use. The inclined surface structure of the top cover facilitates the feeding of materials.

[0017] The outer frame of this material cylinder consists of a base at the bottom and an annular embedded rubber pad. This provides friction on the bottom surface when the material cylinder is placed on the disperser platform. Combined with the magnetic block in the center of the bottom surface, it can adhere to the platform and maintain stable placement. The corrugated structure of the outer wall of the outer frame can also increase the contact friction after clamping by the clamping structures on both sides of the disperser through the corrugated structure on the surface, thereby maintaining the clamping stability on both sides and providing high stability for the dispersion, mixing and grinding process.

[0023] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0024] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0025] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0026] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides, for example Figure 1-4 The material screening cylinder for a sand mill dispersion mixer shown includes a main cylinder 1, an inner cylinder frame 2 fastened to the top of the main cylinder 1, an outer cylinder frame 101, corrugated layers 102 distributed on the outer walls of the outer cylinder frame 101, a base 103 fixed to the bottom of the outer cylinder frame 101, a rubber pad 104 embedded in the bottom surface of the base 103, and a magnetic block 105 fixed to the center of the base 103.

[0029] To ensure the stability of the integral material cylinder during placement and use in the sand milling process of a disperser, such as Figure 1-2 As shown, the outer cylinder frame 101 of this material cylinder is composed of a base 103 at the bottom and an annular embedded rubber pad 104. When this material cylinder is placed on the disperser platform, it provides friction on the bottom surface. In conjunction with the magnetic block 105 in the middle of the bottom surface, it can be attracted to the platform and maintain stable placement. The corrugated layer 102 structure on the outer wall of the outer cylinder frame 101 can also increase the contact friction after clamping when it is clamped by the clamping structures on both sides of the disperser through the corrugated structure on the surface, thereby maintaining the clamping stability on both sides and providing high stability for the dispersion and mixing grinding process.

[0030] like Figure 3-4 As shown, the inner cylinder frame 2 includes a top cover 201. The bottom surface of the top cover 201 is provided with a slot 202 around the perimeter. The top surface of the top cover 201 is surrounded by an inclined surface 203. The bottom end of the top cover 201 is fixedly connected to the inner cylinder wall 204. The bottom end of the inner cylinder wall 204 is fixed with an inner cylinder bottom plate 205. The inner cylinder wall 204 is provided with a sieve hole 206 around the perimeter. The inner cylinder wall 204 is provided with a grinding chamber 207 inside. The outer wall of the inner cylinder wall 204 is provided with a collection chamber 208.

[0031] To facilitate simultaneous screening of materials during the sand milling process, such as Figure 2-4 As shown, this material cylinder is composed of an outer cylinder frame 101 and an inner cylinder wall 204 and an inner cylinder bottom plate 205 connected by a top cover 201. During the grinding process, qualified material particles will be discharged into the collection chamber 208 through the sieve holes 206 arranged around the inner cylinder wall 204 by the centrifugal force of stirring, while unqualified particles will continue to flow into the inner cylinder bottom plate 205 through the sieve holes 206 at the bottom in an inclined state and be ground during the stirring process, thereby completing the integration of grinding and screening processes, improving efficiency and convenience.

[0032] The inner cylinder wall 204 and the inner cylinder bottom plate 205 are connected by the top cover 201 to form an internal grinding chamber 207 structure. The top cover 201 can be fastened to the top surface of the outer cylinder frame 101 through the slot 202 at the bottom, which is convenient for disassembly, installation and use. The inclined surface 203 structure on the surface of the top cover 201 facilitates the feeding of materials.

[0033] In summary, when using this material cylinder, the user first puts the material to be processed and the grinding media into the grinding chamber 207. Most of the material sinks to the bottom of the inner cylinder bottom plate 205. Then, the outer cylinder frame 101 is placed on the platform of the disperser, and the stirring shaft of the dispersant is operated to enter the grinding chamber 207. At this time, the clamping structure of the disperser clamps the outer walls on both sides of the outer cylinder frame 101. Then, the position is kept stable, and the motor is turned on to drive the stirring shaft to grind and stir the material and grinding media in the cylinder. When the material particles meet the grinding requirements, they are screened out from the surrounding screening holes 206 by the centrifugal force of stirring and fall into the collection chamber 208, thus completing the screening process. Then, the top cover 201 is pulled out from the top, and the qualified material in the collection chamber 208 can be collected.

[0034] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
