Description

Technical Field

[0001] This utility model relates to the field of preservative production technology, specifically a negative pressure dust removal device for preservative production. Background Technology

[0002] In industrial production and daily life, preservatives are a class of frequently used functional substances. They are chemical substances or natural extracts that can inhibit the growth and reproduction of microorganisms or prevent microorganisms from causing spoilage and deterioration, thereby extending the shelf life of products and maintaining the stability of product performance.

[0003] In the production of preservatives, the processes of conveying, mixing, and crushing raw materials generate a large amount of dust. This dust not only pollutes the production environment and endangers the health of operators, but may also cause safety accidents such as dust explosions. Currently, commonly used dust collection devices mostly employ a single filtration structure, which easily leads to dust accumulation and blockage of the filter bags, thus affecting dust collection efficiency. Therefore, there is an urgent need to design a negative pressure dust collection device for preservative production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure dust removal device for preservative production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An inverted umbrella-shaped filter bag is fixedly installed on the inner wall of the annular seat. A cleaning component for cleaning the umbrella-shaped filter bag is provided on the filter bag dust collector.

[0007] Furthermore, the cyclone dust collector assembly includes a cyclone dust collector cylinder, a central tube, a feed pipe, and an air outlet pipe. The cyclone dust collector cylinder is fixedly installed on a support frame, the central tube is fixed at the middle of the top inner wall of the cyclone dust collector cylinder, the air outlet pipe is fixed at the middle of the top of the central tube, and the top of the air outlet pipe is fixedly connected to the bottom of the guide pipe.

One of the collection pipes is fixedly connected to the bottom of the cyclone dust collector. A valve is fixedly installed at the bottom of the filter bag dust collector, and a dust discharge pipe is fixedly installed at the bottom of the valve and the top of the other collection pipe.

[0009] Furthermore, the cleaning assembly includes an L-shaped mounting tube fixedly installed on the filter bag dust collector cylinder, and a guide sleeve is fixedly installed on the top inner wall of the L-shaped mounting tube. The top surface of the guide sleeve is designed to be inclined. A threaded cylinder is slidably installed on the inner wall of the guide sleeve, and a connecting cover is fitted on the top of the threaded cylinder. A spring is fixedly connected to the inner wall of the connecting cover and the top of the threaded cylinder. The outer wall of the connecting cover is fixedly connected to the inner wall of the umbrella-shaped filter bag. A support rod is fixedly installed on the inner wall of the annular seat, and a top rod is fixedly installed at the bottom middle of the support rod. The top rod is located on the top of the connecting cover. A reciprocating mechanism for driving the threaded cylinder to rise and fall is provided on the L-shaped mounting tube.

[0010] Furthermore, the reciprocating mechanism includes a connecting pipe fixed to the bottom of the L-shaped mounting tube, and a threaded column is rotatably connected to the inner wall of the connecting pipe through a sealed bearing. The threaded column is screwed to the inner wall of the threaded cylinder. One end of the L-shaped mounting tube has a mounting hole, and the inner wall of the mounting hole is rotatably connected to a drive shaft through a bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a two-stage synergistic dust removal structure of "cyclone dust removal + filter bag dust removal" is adopted. First, the cyclone dust removal component uses centrifugal force to separate most of the coarse dust particles. Then, the inverted umbrella-shaped filter bag performs high-precision filtration of fine dust, which greatly improves the dust capture rate and avoids the problem of incomplete purification caused by a single filtration structure.

[0015] In this invention, a reciprocating mechanism drives the threaded cylinder to rise and fall. Combined with the compression of the connecting cover by the top rod and the rebound of the spring, the umbrella-shaped filter bag produces regular opening and closing and vibration, which efficiently shakes off the dust accumulated on the surface of the filter bag. This eliminates the need for frequent manual disassembly and cleaning, reducing manual maintenance costs and avoiding the decrease in dust removal efficiency caused by filter bag clogging. It also reduces the wear and tear on the filter bag caused by repeated disassembly and extends its service life.

[0016] In this invention, the entire device can achieve automated control of the negative pressure fan start-up and shutdown, cleaning component operation and valve opening and closing through the linkage of timer and controller, without the need for real-time manual supervision, thus reducing the complexity of operation. In addition, the dust from the cyclone dust collector and the filter bag dust collector is collected into the collection box through the collection pipe, which is collected centrally and facilitates subsequent processing.

The rotation of the threaded post 137 causes the threaded cylinder 139, which is screwed to the threaded post 137 and guided by the guide sleeve 1310, to rise and fall accordingly. The connecting cover 1311 at the top of the threaded cylinder 139, under the action of the push rod 134 and the spring 1312, causes the umbrella-shaped filter bag 14 to open and close, vibrating and efficiently shaking off accumulated dust from the filter bag surface.

The cyclone dust collector 31 in the cyclone dust collector assembly 3 is connected to the dust-laden airflow through the tangentially inclined feed pipe 33. The airflow forms a rotational motion in the cyclone dust collector 31, and most of the coarse dust particles are separated and fall to the bottom by means of centrifugal force. At the same time, the preliminarily purified airflow is transported to the filter bag dust collector 7 through the guide pipe 6 through the central pipe 32 in the middle of the inner wall of the top of the cyclone dust collector 31 and the air outlet pipe 34 connected thereto. The umbrella-shaped filter bag 14 in the filter bag dust collector 7 filters the fine dust.

[0029] During the dust removal process, the cleaning component 13 on the filter bag dust collector 7 is responsible for cleaning the umbrella-shaped filter bag 14. The drive shaft 135 is driven by the forward and reverse motor 132, and the threaded column 137 is rotated by the meshing action of the bevel gear 138. This causes the threaded cylinder 139, which is screwed to the threaded column 137 and guided by the guide sleeve 1310, to rise and fall accordingly. The connecting cover 1311 at the top of the threaded cylinder 139 causes the umbrella-shaped filter bag 14 to open and close and vibrate under the action of the top rod 134 and the spring 1312. The dust that is shaken off and the dust separated from the cyclone dust collector 31 are respectively discharged into the collection box 2 through the valve 10, the dust discharge pipe 11 and the collection pipe. The entire device realizes the automatic control of the negative pressure fan 9, the valve 10 and the cleaning component 13 through the timer 4 and the controller 5, so as to complete the efficient dust removal and dust collection.
