Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust collector for the crushing and processing of yeast starter. Background Technology

[0002] In the process of brewing baijiu (Chinese liquor), the crushing of yeast is a crucial pre-processing step. This process generates a large amount of fine dust rich in nutrients. If this dust is not effectively collected and treated, it will cause material waste, environmental pollution, and pose a safety hazard of dust explosion.

[0003] Currently, most dust collectors used for koji crushing employ bag filtration. A fixed air source is installed above the filter bag to blow air onto the inner wall of the filter bag. The airflow blows away the dust trapped on the outer wall of the filter bag, and the blown-off dust is finally discharged through the opening at the bottom of the unit.

[0004] However, this fixed air source purging method has obvious drawbacks: First, because the purging point is fixed, the airflow energy is concentrated in the upper part of the filter bag, resulting in insufficient dust removal in the middle and lower parts of the filter bag, which easily leads to permanent dust retention, i.e., "bag clogging" phenomenon. This increases system resistance and energy consumption. In addition, incomplete dust removal will directly lead to a decrease in dust removal efficiency, affecting the feeding and discharging efficiency of the connected crushing device, and even affecting the stable operation of the entire production system.

[0005] Therefore, we propose a dust collector for the koji crushing process to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a dust collector for the pulverization and processing of yeast starter.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust collector for pulverizing yeast, comprising a body, a cover fixedly provided at the top of the body, and blowing mechanisms equidistantly arranged on the cover; An annular disk is fixedly installed on the upper end of the inner wall of the device, and a filter bag unit is fixedly installed on the annular disk. The blowing mechanism corresponds one-to-one with the filter bag unit, and the blowing mechanism is used to drive the blowing head to move at a constant speed from top to bottom along the central axis of the corresponding filter bag unit.

[0008] Preferably, the filter bag unit includes a ring, a filter bag body fixedly installed on the ring, and a frame fixedly disposed on the ring and supporting the inner wall of the filter bag body.

[0009] Preferably, the purging mechanism includes a fixed base, a purging pipe, and a purging head. The fixed base is fixedly installed on the outer wall of the cover. A screw seat is rotatably provided on the fixed base. A screw rod is threadedly connected to the screw seat. A beam rod is fixedly provided at the top end of the screw rod. The purging pipe is fixedly installed at the end of the beam rod and slidably connected to the cover. The purging head is fixedly provided at the bottom end of the purging pipe and located at the internal central axis of the filter bag unit.

[0010] Preferably, a motor is fixedly mounted on the outer wall of the fixing base, and the output end of the motor meshes with the outer ring surface of the screw base in a gear-like manner.

[0011] Preferably, a sliding seal is provided at the sliding connection between the purge tube and the cover.

[0012] Preferably, the lower end of the outer wall of the device is fixedly provided with legs at equal intervals.

[0013] Preferably, the device body is provided with an air inlet and a suction port, with the air inlet located below the filter bag unit and the suction port located above the ring disc.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a blowing mechanism to drive the blowing head to move downwards at a constant speed from the top inside the filter bag. This design allows the high-pressure airflow to clean the entire length of the filter bag from top to bottom in one continuous and uniform manner. It completely solves the problem of "heavy on top and light on bottom" and ineffective cleaning of the middle and lower parts of the fixed air source, and achieves cleaning of the entire length of the filter bag without dead angles, effectively eliminating the "clogging" phenomenon. The uniform downward motion of the blow head distributes the powerful cleaning energy throughout the entire stroke and time, avoiding the instantaneous strong impact on the filter bag caused by fixed jet cleaning. This "dynamic" cleaning method is gentler and can significantly reduce mechanical damage to the filter bag, thereby extending the service life of the filter bag by several times and reducing maintenance costs. Because the cleaning is more thorough and uniform, the filter bags are always kept in an optimal permeability state, the system operating resistance is low, and energy consumption is reduced. This ensures that the feed inlet of the crushing device connected to the dust collector and the outlet of the yeast powder are always in an efficient and stable working environment, improving the continuity and reliability of the entire crushing production line.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figures 1-4 As shown, the present invention proposes a dust collector for koji pulverization processing, comprising a body 1, which serves as the main body of the entire equipment. The top of the body 1 is sealed with a cover 2 by a flange, together forming a closed dust collection space. Multiple support legs 4 are uniformly welded to the lower end of the outer wall of the body 1 to stably support the entire equipment.

[0019] An air inlet 5 is provided on the side wall of the device body 1. The air inlet 5 is used to connect to the upstream yeast crushing device to introduce dust-laden gas. A ring disk 7 is fixedly installed on the upper part of the inner wall of the device body 1. Above the ring disk 7, a suction port 6 is provided on the side wall of the device body 1. The suction port 6 is used to connect to an external negative pressure air source to form a negative pressure inside the dust collector, forcing the airflow through the filter bag.

[0020] Multiple filter bag units 8 are fixedly installed on the annular disk 7. Each filter bag unit 8 mainly consists of a filter bag body 801, an annular ring 802, and a frame 803. The annular ring 802 is used to fix the filter bag unit 8 onto the annular disk 7. The frame 803 is fixed inside the annular ring 802 and extends into the filter bag body 801. Its core function is to provide rigid support for the soft filter bag body 801, preventing it from being sucked down under negative pressure, and at the same time providing a stable working space for the purging process.

[0021] Multiple blowing mechanisms 3 are equidistantly installed on the cover 2, with their number and position corresponding one-to-one with the filter bag units 8. The blowing mechanism 3 is used to drive the blowing head 307 deep into the corresponding filter bag unit 8 during dust removal, and to move downward at a constant speed along its central axis to thoroughly remove the dust adhering to the outer wall of the filter bag.

[0022] The specific structure of each purging mechanism 3 is as follows: a fixed seat 301 is fixedly installed on the top of the outer wall of the cover 2 by bolts. A screw seat 302 is rotatably installed on the fixed seat 301 through a bearing. The screw seat 302 has a threaded hole machined in the center. A screw 303 forms a threaded engagement with the threaded hole. A horizontal beam 305 is fixedly connected to the top of the screw 303. A purging pipe 306 is vertically fixedly installed at the end of the beam 305. The purging pipe 306 passes through the opening on the cover 2 and achieves a dynamic seal with the cover 2 through a sliding seal, thereby ensuring that the purging pipe 306 can slide up and down without damaging the sealing of the body 1. A purging head 307 is installed at the bottom of the purging pipe 306. When the equipment is in standby mode, the purging head 307 is located at the upper end inside the filter bag unit 8.

[0023] To achieve the drive, a motor 304 is fixedly installed on the outer wall of the fixed base 301. A gear is installed on the output shaft of the motor 304. The gear meshes with the gear teeth machined on the outer ring surface of the screw seat 302. When the motor 304 starts, it will drive the screw seat 302 to rotate, and then drive the screw 303 to make precise linear motion through the thread transmission. Finally, the beam rod 305 pushes the purge pipe 306 and the purge head 307 to move downward at a constant speed inside the filter bag.

[0024] Furthermore, a centralized pulse air source is connected to the top of the purge pipe 306 via a high-pressure hose. This air source consists of an air compressor, an air tank, and a pulse valve. The pulse valve is controlled by a central controller, which, according to a preset program, intermittently injects high-pressure, short bursts of compressed air into the purge pipe 306 as the purge head 307 descends at a constant speed. This pulse airflow is ultimately ejected from the purge head 307, causing the filter bag body 801 to momentarily bulge and vibrate slightly.

[0025] Working principle: During normal filtration, an external negative pressure fan draws air through suction port 6, creating a negative pressure inside the unit 1. Dust-laden gas enters through inlet 5 and flows through filter bag unit 8. Dust is trapped on the outer surface of the filter bag body 801, and the purified gas enters above the annular disc 7 and exits through suction port 6. When cleaning is required, the motor 304 of the blowing mechanism 3 is started, driving the blowing head 307 to descend uniformly from the top of the filter bag. Simultaneously, compressed air is intermittently injected into the blowing pipe 306 through a pulse valve and ejected from the blowing head 307. The high-speed airflow blows away the dust from the outer wall of the filter bag. The blown-off dust settles to the bottom of the unit 1 under gravity and is discharged through the bottom ash discharge valve, completing an efficient and thorough cleaning process.

[0026] It should be noted that the 304 motor structure is a mature existing technology, and its working principle and internal structure are known to those skilled in the art. This utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
