Abstract

This utility model discloses a vibrating pulse dust collector, relating to the technical field of dust removal equipment. It includes a dust collection box and a drive assembly mounted on the dust collection box. A tube sheet is fixedly installed inside the dust collection box, dividing it into upper and lower chambers. A fan is fixedly installed on one side of the upper chamber, with its input end connected to the interior of the upper chamber. An air inlet is opened on one side of the lower chamber. Multiple sets of tube sheet holes are equidistantly spaced along the length of the tube sheet, and filter bags are fixedly installed within these holes. A rectangular frame is provided between adjacent sets of tube sheet holes. A sliding rod is slidably installed inside the dust collection box along its length.

This effectively solves the problems of low impact force at the bottom of the filter bags and incomplete dust removal.

Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a vibrating pulse dust collector. Background Technology

[0002] Existing baghouse dust collectors mainly use pulse jet cleaning. When high-pressure pulse gas cleans the bags, the impact force of the high-pressure air blown in from the top is smaller as it gets closer to the bottom of the bag, and the cleaning effect is worse.

[0003] Therefore, it is necessary to propose a vibrating pulse dust collector to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a vibrating pulse dust collector to solve the problem mentioned in the background art that the existing bag dust collectors mainly use pulse jet cleaning, and when the high-pressure pulse gas is used to clean the bag, the impact force of the high-pressure air blown in from the top is smaller as it gets closer to the bottom of the bag, and the cleaning effect is worse.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A vibrating pulse dust collector includes a dust collection box and a drive assembly mounted on the dust collection box. A tube sheet is fixedly installed inside the dust collection box, dividing the dust collection box into upper and lower chambers. A fan is fixedly installed on one side of the upper chamber, and the input end of the fan is connected to the interior of the upper chamber. An air inlet is opened on one side of the lower chamber. Multiple sets of tube sheet holes are equidistantly opened along the length of the tube sheet, and a filter bag is fixedly installed in the tube sheet holes. A rectangular frame is provided between two adjacent sets of tube sheet holes. A sliding rod is slidably installed inside the dust collection box along its length. The bottom of the multiple rectangular frames is fixedly connected to the sliding rod. The drive assembly is connected to the sliding rod and drives the sliding rod to reciprocate.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Example 1: This Example 1 provides a vibrating pulse dust collector, which is a direct improvement on existing dust collection equipment. It has a unique structure. Please refer to [link / reference]. Figure 1-5As shown, it includes a dust collector 1, which is welded from Q235 carbon steel plate. The inside of the box is divided into an upper chamber (clean air chamber) and a lower chamber (dust chamber) by a tube sheet 2. A fan 4 is fixedly installed on the left side wall of the upper chamber by bolts. The fan input end is sealed to the upper chamber by a flange. An air inlet 6 is opened on the right side wall of the lower chamber.

[0015] Two lifting lugs 8 are symmetrically welded along the length of the top of the box to facilitate crane lifting. A double-layered tempered glass observation window 7 is installed on the front side of the upper chamber, and an explosion-proof window 9 is installed on the right side wall of the lower chamber. When the internal pressure exceeds the preset pressure, it will automatically release pressure. An inspection door 5 is installed on the front side, and the door frame is fitted with a high-temperature resistant silicone sealing strip.

[0016] The tube sheet 2 is made of 304 stainless steel plate with a thickness of 8mm, and is fixed to the support frame on the inner wall of the dust collector 1 by welding. Twelve sets of tube sheet holes are equally spaced along the length of the tube sheet 2. Each set of tube sheet holes includes two circular mounting holes symmetrically arranged along the width of the tube sheet 2. The filter bag 3 is fixed in each mounting hole by clamps. A rectangular frame 17 is set between two adjacent sets of tube sheet holes. The rectangular frame 17 is welded from four 304 stainless steel square tubes, and reinforcing ribs are welded at the four corners to improve the structural strength.

[0017] The bottom of the rectangular frame 17 is fixedly connected to the slide rod 15 by bolts. The front and rear sides of the inner wall of the dust collector 1 are fixedly installed with slide rails 19 by bolts. The slide plate 18 is slidably installed in the slide rail. The slide plate 18 is connected to the side of the rectangular frame 17 by bolts to form a sliding guide structure. The slide rod 15 is slidably fitted with a sleeve 16 (made of brass). The sleeve 16 is fixedly connected to the left side wall of the dust collector 1 by M12 bolts, which serves to axially position and reduce friction.

[0018] The drive assembly consists of a motor 10, a reducer 11, a rotating disk 12, a connecting rod 14, and a rotating shaft 13. The motor 10 is fixed to the motor bracket on the left side of the dust collector 1 by bolts. The input shaft of the reducer 11 is connected to the output shaft of the motor by a coupling, and the output shaft is fixedly connected to the rotating disk 12 by a flat key. The rotating shaft 13 is welded to the eccentric position below the rotating disk 12. The two ends of the connecting rod 14 are connected to the rotating shaft 13 at the end of the slide rod 15 and the rotating shaft 13 of the rotating disk 12 by bearings, respectively, to form a crank-slider mechanism.

[0019] When the motor starts, the reducer 11 drives the rotating disk 12 to rotate. Since the rotating shaft 13 on the rotating disk 12 is off-center, the connecting rod 14 pushes the slide rod 15 to make reciprocating linear motion in the sleeve 16. The reciprocating motion of the slide rod 15 drives multiple rectangular frames 17 to move. During the movement, the rectangular frames 17 vibrate the bags 3 on both sides. The vibration force is transmitted to the filter material layer through the bags, causing the dust layer attached to the surface of the bags to fall off to the bottom of the lower chamber.

[0020] Working principle: During dust removal, the fan 4 is started to create negative pressure in the upper chamber. Dust-laden gas enters the lower chamber through the inlet 6. The dust is trapped by the filter bags 3, and the clean gas passes through the filter bags into the upper chamber and is finally discharged by the fan. When a lot of dust accumulates on the filter bags 3, the motor 10 is started, and the drive assembly drives the rectangular frame 17 to reciprocate, vibrating and cleaning the filter bags.

[0021] Example 2: The difference between Example 2 and Example 1 is that a control panel (not shown in the figure) and a differential pressure sensor (not shown in the figure) for detecting the pressure of the upper and lower chambers are fixedly installed on the dust collector 1. The fan 4, motor 10, and differential pressure sensor are all connected to the control panel. When the differential pressure sensor detects that the pressure difference of the dust collector exceeds 1200Pa (indicating that the filter bag is seriously dusty), the control panel automatically starts the motor 10, and the drive component drives the rectangular frame 17 to reciprocate to vibrate and clean the filter bag. The vibration process lasts for 3-5 minutes. When the pressure difference drops to below 800Pa, the vibration stops and the dust collection operation resumes.

[0022] 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.
