Description

Technical Field

[0001] This utility model relates to the technical field of dustproof pulverizers, specifically a low-temperature dustproof pulverizer for benzyl amino alcohol. Background Technology

[0002] In the fields of medicine, chemical engineering, and materials science, benzyl amino alcohols are widely used due to their unique chemical and biological activities. These compounds are usually white to off-white solid powders, exhibit significant basicity, and are soluble in strongly polar organic solvents. However, their physical properties impose special requirements on processing techniques, especially during the pulverization process.

[0003] In existing technologies, cryogenic pulverization is commonly used for pulverizing heat-sensitive materials. For example, CN205236094U discloses a cryogenic pulverizer for traditional Chinese medicine, which achieves an adjustable low-temperature environment from -196℃ to room temperature through liquid nitrogen precooling combined with a cooling water circulation system, effectively inhibiting material denaturation. However, this technology does not have specific protective measures designed for the risk of dust explosion, and its open pulverizing cylinder and screening structure still pose a problem of dust emission.

Detailed Implementation

[0026] This utility model embodiment provides a low-temperature dustproof pulverizer for benzyl amino alcohol, such as... Figure 1-6 As shown, the device includes a main body 101, a main body housing 105, and a grinding tank 118. The main body 101 has a vertically erected main body housing 105 at its top. The grinding tank 118 is installed inside the main body housing 105. A stabilizing ring 113 is installed between the grinding tank 118 and the inner wall of the main body housing 105, which provides a stable connection. A threaded temperature control pipe 117 is fixedly installed on the outer end face of the grinding tank 118. A grinding chamber 119 is provided inside the grinding tank 118. A drive shaft 115 is rotatably installed inside the grinding chamber 119. Several grinding blade sets 116 are fixedly installed on the outer end face of the drive shaft 115, which provide a grinding effect.

[0027] Furthermore, a conical collecting cone 104 is installed at the bottom of the crushing tank 118, and an opening groove 112 with an outward opening is provided inside the main body 101, through which the lower end of the collecting cone 104 passes.

[0028] Furthermore, the collecting cone 104 is provided with a collecting trough 114 that communicates with the crushing chamber 119, and the bottom of the collecting cone 104 is provided with a discharge port 103 that serves as an output outlet, which is connected to the collecting trough 114.

[0029] Furthermore, the temperature control pipe 117 is connected to a cold air pipe interface 106 at both ends, with one end of the cold air pipe interface 106 penetrating through the main unit housing 105 and extending outward.

[0030] It should be further explained that the air conditioning pipe interface 106 at the bottom is the input port, and the drive motor 107 at the top is the output port.

[0031] Furthermore, a drive motor 107 is installed at the top of the pulverizing tank 118, and the top of the drive shaft 115 is poweredly connected to the drive motor 107.

[0032] It is worth further explaining that when the drive motor 107 starts, it can drive the drive shaft 115 to rotate, which in turn drives the crushing blade assembly 116 to rotate and achieve the crushing effect.

[0033] It should be further noted that the shredder assembly 116 is distributed with a larger size at the top and a smaller size at the bottom.

[0034] Furthermore, a removable sealing cover 111 is installed on the top of the main unit housing 105 to achieve a sealing effect.

[0035] Furthermore, a dust removal interface 108 is connected to one side of the top of the pulverizing tank 118, and a dust suction pipe 109 is installed and connected to the other end of the dust removal interface 108. A dust filter 110 is connected to the other end of the dust suction pipe 109.

[0036] It should be further explained that the dust filter 110 has a dustproof cloth inside for a preliminary filtration effect, and the suction pipe 109 has a suction pipe inside, which, together with the dustproof cloth, achieves a combined filtration effect.

[0037] Furthermore, support feet 102 are fixedly connected to the four corners of the bottom of the main body 101, and the support feet 102 play a role in providing stable support.

[0038] The usage method of this solution is as follows:

[0039] S1. Connect the liquid nitrogen delivery pipe to the bottom cooling pipe interface 106 to turn on the liquid nitrogen supply.

[0040] Liquid nitrogen flows through the threaded pipe of the temperature control pipe 117 to uniformly cool the pulverizing tank 118, reducing the temperature inside the tank to -196℃ to -50℃.

[0041] The grinding chamber is fully pre-cooled to prevent localized heating during subsequent grinding, which could lead to material denaturation.

[0042] S2. Open the sealing cover 111, put the benzyl amino alcohol solid into the crushing chamber 119, and immediately close the sealing cover;

[0043] The operation must be completed quickly while maintaining a low temperature environment to prevent the material from absorbing moisture or heating up.

[0044] S3. Turn on the negative pressure device of the dust filter 110 to generate directional airflow in the suction pipe 109.

[0045] Before crushing, an internal negative pressure environment is established to prevent dust from escaping from gaps.

[0046] S4. Start the drive motor 107 to drive the drive shaft 115 and the stepped crushing blade assembly 116 to rotate at high speed.

[0047] The blade layout, with larger blades at the top and smaller blades at the bottom, creates a vortex-like crushing force field. Larger particles are pre-crushed in the upper layer, while finer particles are further ground in the lower layer, improving efficiency and reducing temperature rise.

[0048] S5. Liquid nitrogen is continuously introduced during the crushing process, and the temperature is dynamically adjusted through the temperature control pipe 117.

[0049] The generated dust is sucked into the dust collection pipe 109 through the dust collection interface 108, and after being initially filtered by the dustproof cloth, it enters the high-efficiency filter for secondary interception.

[0050] S6. The pulverizer is kept under a closed negative pressure throughout the process, and the dust concentration is always below the lower explosive limit.

[0051] S7. After crushing, the material slides into the collection trough 114 through the collection cone 104 and is discharged from the discharge port 103.

[0052] Turn off the liquid nitrogen and the motor. After the tank temperature rises to room temperature, disassemble the sealing cap 111 and the knife assembly for cleaning.

[0053] 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.
