Problems solved by technology

The main disadvantages of the single-stage pulverizer are: 1) If the material block is large, the large block cannot easily enter the crushing mechanism, and it is easy to block the feeding port of the crushing mechanism, causing the machine to run idly and increasing wear; 2) The large block of material enters the crushing mechanism After the machine, the crushing mechanism needs to crush for a long time, the efficiency is low, and the machine rotates for a long time, the heat is obvious, and it is easy to damage the machine
[0003] However, if a multi-stage pulverizer is used, there are still some problems in the multi-stage pulverizer in the prior art. In the pharmaceutical production process, hammers are often used to crush large materials into small pieces and then enter the secondary The first-stage crushing chamber is crushed, but when entering the first-stage crushing chamber for crushing, there is still a situation of material clogging, but the effect will be better than that of the single-stage crushing machine. Therefore, in order to prevent the blockage and the machine is idling, it is urgent to design a The multi-stage pulverizer structure without clogging can improve the efficiency of drug pulverization

Embodiment approach 1

[0037] The present invention relates to the technical field of material crushing. The shredder structure commonly used in machinery is applied to the field of drug crushing, and discloses a non-blocking multi-stage pulverizer. The pulverizer mainly includes a feeding funnel 1 communicating with the feeding funnel 1. The multi-stage crushing mechanism and the total discharge port 4 connected with the multi-stage crushing mechanism, the multi-stage crushing mechanism includes a primary crushing chamber 2 and a secondary crushing chamber 3 located below the primary crushing chamber 2, see the attached figure 1 . The feeding funnel 1 and the multi-stage crushing mechanism are all arranged on the table top of the box body 7, and the total discharge port 4 is located on the side wall of the box body 7, and communicates with the multi-stage crushing mechanism through the discharge channel 6, see the attached figure 1, the detailed structure is as follows:

Embodiment approach 2

[0052] This embodiment is a further optimization of Embodiment 1. The specific optimization plan is: on the front and rear inner walls of the first-stage crushing chamber 2, there are several scraper blades 209 detachably connected at intervals (note: the first-stage crushing chamber 2 Among the four sides of the cavity, the two sides through which the knife shaft passes are marked as the left and right sides, and the sides parallel to the knife shaft are marked as the front and rear sides, and scraper blades 209 are arranged on the inner walls of the front and rear sides to scrape The material blades 209 are all plugged into the gap formed by the cutter head 207 on the driving knife shaft 205 and the driven knife shaft 206, and the scraper blades 209 do not affect the rotation of the knife shaft, that is, the scraper blades 209 on the front side are plugged into the active knife shaft. In the gap formed by the cutter disc 207 of the shaft 205 , the scraper blade 209 on the inn...

Embodiment approach 3

[0056] This embodiment is a further optimization of Embodiment 2. The specific optimization plan is: a pair of parallel magnetic pumps 213 are arranged horizontally at the discharge port B203 of the primary crushing chamber 2 and the discharge port D303 of the secondary crushing chamber 3. A pair of magnetic pumps 213 is arranged on the bracket 214, and the bracket 214 can be slidably connected to a pair of slide rails 215, so that the magnetic pump 213 can slide out of the crushing device through the slide rails 214 for cleaning.

[0057] See attached Figure 7 , the magnetic pump 213 is horizontally arranged at the discharge ports B and D, the support 214 is a square frame, the two ends of the magnetic pump 213 are detachably connected to the two ends of the square frame support 214, and the side walls at the two ends of the discharge ports B and D The top is respectively indented to form a pair of slide rails 215 , and the other two ends of the square frame slide inside the...

Abstract

The invention relates to the technical field of material smashing, and discloses a blockage-free multilevel smasher for processing heparinoid. The blockage-free multilevel smasher comprises a feedinghopper, a multilevel smashing mechanism and a main discharging hole, wherein the multilevel smashing mechanism is in communication with the feeding hopper; the main discharging hole is in communication with the multilevel smashing mechanism; the multilevel smashing mechanism comprises a first-level smashing cavity and a second-level smashing cavity which is positioned below the first-level smashing cavity; a feeding hole A of the first-level smashing cavity is in communication with the feeding hopper; a discharging hole B of the first-level smashing cavity is in communication with a feeding hole C of the second-level smashing cavity; a discharging hole D of the second-level smashing cavity is in communication with the main discharging hole; and a shredder principle is adopted by the first-level smashing cavity. Compared with the prior art, the blockage-free multilevel smasher has the advantages that one smashing cavity is added, the shredder principle is adopted by the first-level smashing cavity, and two cutter shafts are used for driving a cutterhead to rotate towards each other to realize a blockage-free material smashing cavity. The two smashing cavities work simultaneously, large material blocks are smashed with the first-level smashing cavity into small material blocks, and the small material blocks enter the second-level smashing cavity for smashing and filtering througha screen, so that the feeding holes of the smashing cavities are prevented from being blocked, and the machine smashing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crushing pharmaceutical materials, in particular to a non-clogging multistage grinder for processing heparinoids. Background technique [0002] During the processing and production of heparinoids, it is necessary to pulverize the prepared blocky large-size solid raw materials to the required size through a pulverizer. This requires a shredder to operate. Existing pulverizers crush materials in the form of hammering, grinding, etc., while most of the pulverizers are single-stage pulverization. The materials pass through the feeding funnel and directly enter the pulverization mechanism for beating and filtering through a screen. Discharge. The main disadvantages of the single-stage pulverizer are: 1) If the material block is large, the large block cannot easily enter the crushing mechanism, and it is easy to block the feeding port of the crushing mechanism, causing the machine to run idly and increasing w...
