Description

Technical Field

[0001] This utility model relates to the field of grinding and sieving technology for suspension production, and in particular to a grinding and sieving structure for suspension production. Background Technology

[0002] A suspending agent is a mixture in which solid particles are suspended in a liquid. It is often used to prepare liquid pharmaceuticals or coatings. In the production process of suspending agents, it is necessary to grind the solid particles into the required size and sieve the ground powder to remove particles that are too large or too small.

[0003] A search revealed Chinese Patent Publication No. CN222174276U, which discloses a grinding and sieving structure for suspension production. The structure includes a shell, a feed hopper movably mounted on the upper surface of the shell, and a discharge port on one side of the shell. The shell contains a grinding mechanism for grinding raw materials for suspension production. In use, this technology uses a vibrator to drive the entire mechanism to vibrate, thereby improving sieving efficiency. However, during use, the screen is rigidly connected to the shell, preventing effective transmission of vibration energy to the screen surface, leading to decreased sieving efficiency and potential material accumulation or blockage. Furthermore, the pre-screened granular raw materials directly enter the grinding structure for further grinding, making it impossible to control the amount of granular material entering the grinding structure, significantly affecting the grinding effect and failing to meet usage requirements. Therefore, this paper proposes a grinding and sieving structure for suspension production to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a grinding and sieving structure for suspending agent production to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding and sieving structure for suspension production, comprising:

[0007] The housing serves as the supporting frame for the entire structure.

[0008] The top of the box is equipped with a feeding hopper for feeding the suspending agent raw material;

[0009] The front side of the enclosure is provided with an enclosure door for inspecting and repairing the components inside the enclosure.

[0010] The box is equipped with two sieving components extending to its right side, which are used for preliminary sieving of suspension material particles and sieving after grinding.

[0011] The box is equipped with a material guiding and grinding mechanism located between two screening components, which is used to guide and grind the granular material after preliminary screening.

[0012] The right side of the box is equipped with a receiving component located below the screening component, which is used to collect the sieved particulate material.

[0013] Preferably, the screening assembly includes four support blocks, which are fixedly installed on the left and right sides of the inner wall of the housing. A connecting plate extending to the outer side is movably installed inside the support block. A connecting spring is fixedly installed between the bottom of the connecting plate and the inner bottom wall of the support block. A baffle that fits against the inner wall of the support block is fixedly installed on the outer side of the connecting plate. A connecting frame is fixedly installed between the connecting plates on the left and right sides. A screening screen extending through to the right side of the housing is movably installed inside the connecting frame. A vibration motor for improving the screening efficiency of the screening screen is fixedly installed on the left side of the connecting frame.

[0014] Preferably, the material guiding and grinding mechanism includes a material guiding hopper, which is fixedly installed inside the housing and located between two sieves. A material guiding pipe communicating with the inside of the hopper is fixedly installed at the bottom of the hopper. A support column located below the material guiding pipe is fixedly installed between the left and right sides of the inner wall of the housing. The top of the support column has an arc-shaped structure design to prevent material accumulation and stagnation. A drive motor is fixedly installed at the bottom of the support column. The output shaft of the drive motor is fixedly connected to a rotating shaft extending into the inside of the material guiding pipe. A spiral blade that fits against the inner wall of the material guiding pipe is fixedly installed on the outer side of the rotating shaft. A grinding cylinder located below the support column is fixedly installed between the left and right sides of the inner wall of the housing.

[0015] Preferably, the receiving assembly includes two mounting frames, which are fixedly installed on the right side of the box and located below the two screens respectively. A receiving box extending to the front side of the mounting frame is movably installed on the inner side of the mounting frame.

[0016] Preferably, the inside of the box door is provided with an observation window, and a receiving frame that extends through the inside of the box is movably installed on the front side of the box door, the receiving frame being located below the screen below.

[0017] Preferably, the number of connecting springs is several and they are evenly distributed. The mesh size of the upper sieve is larger than that of the lower sieve. The connecting frame is designed with an inclined structure. An embedded plate extending into the inner wall of the connecting frame is fixedly installed on the left side of the sieve. An embedded groove adapted to the embedded plate is opened inside the left side of the inner wall of the connecting frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This grinding and sieving structure for suspending agent production, by setting an inclined connecting frame and a vibration motor in the sieving assembly, combined with the buffering effect of the connecting spring, causes the sieve screen to shake and sieve during vibration, which can effectively disperse material accumulation and reduce screen hole blockage, significantly improving the sieving efficiency of suspending agent material particles.

[0020] This grinding and sieving structure for suspending agent production uses a material guiding and grinding mechanism. The material guiding and grinding mechanism uses spiral blades combined with the speed control of the drive motor to uniformly push the pre-screened particles into the grinding cylinder for grinding. This avoids the suspending agent material particles after preliminary screening directly entering the grinding cylinder for grinding, which would affect the grinding effect. This allows the amount of suspending agent material particles ground to be effectively controlled, ensuring the uniformity of the finished product particle size. Attached Figure Description

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0029] Example

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a grinding and sieving structure for suspension production, including a box body 1, which serves as the supporting frame for the entire structure; a feed hopper 2 is fixedly installed on the top of the box body 1 for feeding suspension raw materials; a box door 3 is movably installed on the front side of the box body 1 for inspecting the internal components of the box body 1; an observation window 31 is opened inside the box door 3; a receiving frame 32 that extends through the box body 1 is movably installed on the front side of the box door 3; the observation window 31 facilitates real-time observation of the sieving and grinding status; and the receiving frame 32 can receive the final suspension particles.

[0031] Inside the housing 1, two screening components 4 are fixedly installed, extending to the right side of each component. Each screening component 4 includes four support blocks 41, fixedly installed on the left and right sides of the inner wall of the housing 1. Inside each support block 41, a connecting plate 42 extending to its outer side is movably installed. A connecting spring 43 is fixedly installed between the bottom of the connecting plate 42 and the inner bottom wall of the support block 41. Several connecting springs 43 are evenly distributed. A baffle 44, conforming to the inner wall of the support block 41, is fixedly installed on the outer side of the connecting plate 42 to reduce dust spillage into the support block 41. The connecting plates 42 on the left and right sides are fixedly connected. A connecting frame 45 is installed, and the connecting frame 45 has an inclined structure design. A screen 46 that extends through to the right side of the box 1 is movably installed inside the connecting frame 45. The receiving frame 32 is located below the lower screen 46. The mesh size of the upper screen 46 is larger than that of the lower screen 46. An embedded plate 451 extending into the inner wall of the connecting frame 45 is fixedly installed on the left side of the screen 46. An embedded groove 452 that matches the embedded plate 451 is opened inside the left side of the inner wall of the connecting frame 45. The matching design of the embedded plate 451 and the embedded groove 452 makes it easy for users to quickly assemble and disassemble the screen 46.

[0032] A vibration motor 47 for improving the screening efficiency of the screen 46 is fixedly installed on the left side of the connecting frame 45. The vibration motor 47 adopts a structural component known in the prior art and is used for preliminary screening and post-grinding screening of suspension material particles. This grinding and screening structure for suspension production, by setting an inclined connecting frame 45 and vibration motor 47 in the screening assembly 4, combined with the buffering effect of the connecting spring 43, makes the screen 46 shake and screen during vibration, which can effectively disperse material accumulation and reduce screen hole blockage, and significantly improve the screening efficiency of suspension material particles.

[0033] Inside the housing 1, a material guiding and grinding mechanism 5 is fixedly installed between two screening components 4. The material guiding and grinding mechanism 5 includes a material guiding hopper 51, which is fixedly installed inside the housing 1 and located between two screening screens 46. A material guiding pipe 52 communicating with the inside of the material guiding hopper 51 is fixedly installed at the bottom of the material guiding hopper 51 to concentrate and guide the large particles of material that have been initially screened, so as to avoid the material dispersion and the reduction of grinding efficiency.

[0034] A support column 53 located below the guide pipe 52 is fixedly installed between the left and right sides of the inner wall of the housing 1. The top of the support column 53 has an arc-shaped structure design to prevent material accumulation and stagnation. A drive motor 54 is fixedly installed at the bottom of the support column 53. The output shaft of the drive motor 54 is fixedly connected to a rotating shaft 55 extending into the inside of the guide pipe 52. A spiral blade 56 that fits against the inner wall of the guide pipe 52 is fixedly installed on the outside of the rotating shaft 55. A grinding cylinder 57 located below the support column 53 is fixedly installed between the left and right sides of the inner wall of the housing 1. The grinding cylinder 57 is a known component in the prior art and contains grinding media (such as ceramic balls). Through mechanical friction and impact driven by a motor, large particles are crushed to the target particle size. Combined with the uniform feeding of the feed pipe 52, the grinding uniformity is ensured. The grinding and sieving structure for the production of suspension agent is equipped with a feed grinding mechanism 5. The feed grinding mechanism 5 uses spiral blades 56 combined with the speed control of the drive motor 54 to uniformly push the pre-screened particles into the grinding cylinder 57 for grinding. This avoids the suspension material particles after the initial screening from directly entering the grinding cylinder 57 for grinding, which would affect the grinding effect. It also prevents material congestion or accumulation, so that the grinding amount of suspension material particles can be effectively controlled, ensuring the uniformity of the finished product particle size.

[0035] A receiving component 6 is fixedly installed on the right side of the housing 1, located below the screening component 4. The receiving component 6 includes two mounting frames 61, which are fixedly installed on the right side of the housing 1 and located below the two screening screens 46 respectively. A receiving box 62 extending to the front side is movably installed on the inner side of the mounting frame 61 for receiving and collecting the sieved granular material. The receiving box 62 can be quickly disassembled and assembled to facilitate the classification and collection of finished granules of different sizes and avoid mixing of different sizes.

[0036] The working process of this utility model:

[0037] Step 1: After the suspension raw material enters the box 1 through the feed hopper 2, it first falls onto the surface of the screen 46 of the upper screening component 4. The vibration motor 47 drives the connecting frame 45 to vibrate at high frequency, so that the fine particles that meet the particle size requirements pass through the screen holes and fall into the guide hopper 51. The large particles that do not pass through are conveyed to the right along the inclined screen 46 to the receiving box 62 for collection and further processing.

[0038] Step 2: The drive motor 54 drives the spiral blades 56 to rotate through the rotating shaft 55, pushing the material in the guide hopper 51 through the guide pipe 52 into the grinding cylinder 57 for crushing and grinding; the ground mixture is then screened again through the screen 46 of the lower screening component 4, with fine particles falling into the receiving frame 32 for collection, and substandard particles being transported to the receiving box 62 for collection and further processing.

[0039] Step 3: The two receiving boxes 62 of the receiving component 6 collect finished particles of different sizes respectively, and can be quickly removed and cleaned by sliding; the observation window 31 of the box door 3 facilitates real-time observation of the screening status, and the receiving frame 32 can receive the suspension material particles after final screening.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
