[0001] The utility model relates to the technical field of vacuum drying equipment, in particular to an anti-bridging material cake crushing mechanism of a liquid belt dryer. Background Art

[0002] At present, liquid belt dryers are used for drying raw materials in the pharmaceutical, food, chemical and new energy industries. They are mostly used for drying viscous and highly heat-sensitive liquid materials. The final dried products are mostly solid preparations such as powders and granules. In the final stage of the drying process, the dried material on the crawler of the liquid belt dryer is in the form of solid cakes, which are cut off by the lifting and cutting device and fall into the hopper for transportation by the spiral auger.

[0003] At present, due to the special properties of some materials, such as materials with high sugar content, the final cake-shaped solid has a high hardness, which is easy to cause material accumulation and bridging when falling into the hopper, making it impossible to transport. In addition, the internal environment of the equipment is a vacuum environment and cannot be handled manually. In severe cases, it will cause equipment shutdown and production line shutdown. Especially for materials such as medicines and foods that have extremely high requirements for hygiene levels, the liquid belt dryer is shut down to handle bridging materials, which is easy to cause microbial contamination in the environment inside the equipment, and it needs to be cleaned, sterilized, and dried again before it can be used again.

[0004] Therefore, there is an urgent need for a device that can assist in crushing the falling materials to process the block cakes in the hopper so that they can smoothly enter the auger for crushing and transportation to achieve continuous production. Utility Model Content

[0028] The following is an explanation of the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] See also Figure 1 to Figure 2 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions for the implementation of the utility model, so they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

[0030] See also Figure 1 The utility model discloses an anti-bridging cake crushing mechanism for a liquid belt dryer, so as to improve the problem that the block cakes in the hopper 110 are easily accumulated and bridged in the hopper 110 during the use of the existing liquid belt dryer. The anti-bridging cake crushing mechanism for the liquid belt dryer includes a cylinder 100, a hopper 110 and a cleaning mechanism 200, so as to clean the block cakes accumulated in the hopper 110 through the cleaning mechanism 200.

[0031] Specifically, the hopper 110 is located in the cylinder 100, and at least one crawler 120 is provided above the hopper 110. In the actual production process, the material is transported into the hopper 110 through the crawler 120. At the same time, a discharge port 111 is connected to the bottom of the hopper 110, and the material passing through the hopper 110 is discharged through the discharge port 111. It should be noted that a discharge dragon can be connected to the position of the discharge port 111. Through the discharge dragon, the material can be crushed and discharged.

[0032] See also Figure 1 In one embodiment, the cleaning mechanism 200 is disposed at the hopper 110 to facilitate cleaning of the block cakes accumulated in the hopper 110 .

[0033] Specifically, the cleaning mechanism 200 includes two sets of crushing bars 210 and a driving assembly 220 for driving the crushing bars 210. The two sets of crushing bars 210 are respectively located on the inner side walls of the hopper 110, and one end of the crushing bars 210 is pivotally connected to the side wall of the hopper 110. The driving assembly 220 is drivingly connected to the crushing bars 210 and can be used to drive the crushing bars 210 to rotate along their rotation center.

[0034] Furthermore, a single group of crushing bars 210 may be provided with multiple crushing bars 210. The multiple crushing bars 210 may effectively improve the crushing of the block-shaped cakes accumulated in the hopper 110. At the same time, the multiple crushing bars 210 between the two groups may be staggered to improve the crushing effect in actual use.

[0035] It should be noted that the two groups of breaker bars 210 rotate simultaneously and in the same direction.

[0036] See also Figure 1 and Figure 2 In one embodiment, a rotating shaft 211 is fixedly connected to the connecting end of the crushing rod 210 and the side wall of the hopper 110 , and the rotating shaft 211 is rotatably connected to the side wall of the hopper 110 .

[0037] Further, the driving mechanism may include a lifting cylinder 221, a lifting frame 222, a cross bar 223, a gear 224 and a rack 225. The lifting cylinder 221 is located above the cylinder 100, and the lifting frame 222 is fixedly connected to the end of the cylinder rod of the lifting cylinder 221. One end of the rack 225 is fixedly connected to the cross bar 223, and the rack 225 and the gear 224 are meshed. It can be understood that the gear 224 is fixedly connected to the rotating shaft 211, and the gear 224 and the rotating shaft 211 are fixedly connected. Therefore, when the gear 224 rotates, the rotating shaft 211 can be driven to rotate synchronously.

[0038] It should be noted that the crushing rod 210 is allowed to fit on the side wall of the hopper 110. At the same time, the two sets of crushing rods 210 can be stopped at any position by adjusting the lever stroke of the lifting cylinder 221. Specifically, when the lifting cylinder 221 is in the normally closed state, the crushing rod 210 on one side is allowed to face upward and be in an open state, and the crushing rod 210 on the other side is allowed to face downward and fit on the hopper 110 and be in a closed state.

[0039] See also Figure 1In one embodiment, when the lifting cylinder 221 is in a normally closed state, the lifting frame 222 is located at an upper position. The crushing rod 210 on one side is opened upward, and the crushing rod 210 on the other side is closed downward and close to the hopper 110. In this state, it is greatly convenient for manual maintenance and cleaning of the equipment.

[0040] When the solid cake from the crawler 120 falls into the hopper 110 and is laid horizontally to form a bridge, the lifting cylinder 221 moves downward, causing the lifting frame 222 to move downward as well. At the same time, the crossbar 223 and the rack 225 are driven to move downward. The gear 224 on the rotating shaft 211 rotates clockwise under the action of the rack 225. The crushing rod 210 on the rotating shaft 211 can press the bridging material downward and enter the discharge port 111. At the same time, the material in the crushing port is crushed and discharged by the discharge dragon.

[0041] It should be noted that the crushing rod 210 on one side moves clockwise, closes downward and fits the hopper 110. The crushing rod 210 on the other side also moves clockwise, flips the bridged material upward and moves vertically upward, and this process is a material flipping and crushing movement process. It can be understood that when the lifting cylinder 221 moves upward and closes, the crushing rods 210 on both sides move counterclockwise, move upward and downward respectively, so that the material is flipped in the opposite direction again, squeezed into the auger, and crushed and output.

[0042] In summary, the utility model discloses an anti-bridging material cake crushing mechanism of a liquid belt dryer, which is provided with a reversible crushing rod 210 in the hopper 110, and the gear 224 on the rotating shaft 211 performs a rotational motion under the action of the rack 225. The bridging material is pressed down and enters the discharge port 111, so that the material in the crushing port is crushed and discharged through the discharge dragon.

[0043] Therefore, the problem of material accumulation and bridging in the hopper 110 of the block-shaped material cakes in the hopper 110 during use of the existing liquid belt dryer can be effectively improved.

[0044] Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
