CN209791108U - An Improved Bag Dust Collector - Google Patents

Abstract

The utility model discloses an improved bag-type dust collector, which comprises a blowback pipe installed in the dust collector and a cloth bag located below the blowback pipe. A support plate is horizontally arranged in the dust collector below the blowback pipe. With the cloth bag containing hole, the cloth bag opening is fitted on the surrounding wall of the cloth bag containing hole, and the inside of the bag opening is sequentially set with a cylindrical keel frame and a cylindrical protective cover, the outer periphery of the upper end of the cylindrical protective cover and The outer periphery of the upper end of the cylindrical keel frame is turned outward to form a flanging, and the upper edge of the bag mouth is pressed on the edge of the hole of the cloth bag. The utility model can improve the damage phenomenon of the bag mouth caused by the back blowing pipe not being in the center of the bag mouth, improve the service life of the dust-removing cloth bag, and ensure the pass rate of the dust collector.

Description

An Improved Bag Dust Collector

technical field

The utility model relates to an improved bag-type dust collector.

Background technique

The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filter function of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purified. The structure of the bag filter is mainly composed of the upper box, the middle box, the lower box (ash hopper), the dust cleaning system and the dust discharge mechanism. The core of the bag filter is the dust cleaning system of the bag. At present, the mainstream method is to use compressed air to blow back regularly to achieve the air permeability of the bag. However, some problems are also reflected in the actual operation situation. Since the center distance between the blowback pipe and the bag mouth of the bag is deviated during the installation of the dust collector, the mouth of the bag is often blown to pieces during the operation, causing the dust collector to discharge outside, and the entire warehouse Pollution.

Contents of the invention

The purpose of this utility model is to provide an improved bag-type dust collector, which can improve the damage phenomenon of the bag mouth caused by the blowback pipe not being in the center of the bag mouth, improve the service life of the dust bag, and ensure the pass rate of the dust collector.

The purpose of this utility model is achieved in this way, an improved bag filter, including a blowback pipe installed in the dust remover and a cloth bag located below the blowback pipe, and a support plate is horizontally arranged in the dust collector below the blowback pipe , the support plate is provided with a cloth bag containing hole, and the bag mouth is fitted on the surrounding wall of the cloth bag containing hole, and a cylindrical keel frame and a cylindrical protective sleeve are arranged in the bag mouth from the outside to the inside in sequence, and the cylinder protects The outer peripheral edge of the upper end of the cover and the outer peripheral edge of the upper end of the cylindrical keel frame are all turned outward to form a flanging, and the upper edge of the bag mouth is pressed on the hole edge of the cloth bag containing hole.

Since the dust collector with bag mouth protector was installed, the bag mouth of the dust collector bag has not been blown by the blowback system, and it is different from the traditional venturi tube protector in the past. After the tube, because the Venturi tube is a reduced-diameter tube, it plays a very good role in concentrating the blowback volume, but due to the reduced diameter, it will reduce the filter area of the dust collector and hinder the wind speed of the dust collector; The cylinder protective cover in the new type is a vertical cylinder, which not only protects the bag mouth but also does not affect the performance of the dust collector, and finally ensures the life of the dust collector bag, prevents the dust collector from being discharged, and protects the environment.

Description of drawings

The utility model will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the front view structure schematic diagram of existing bag filter;

Fig. 2 is a schematic diagram of the front view of the pocket of the bag filter of the utility model.

Detailed ways

An improved bag filter, as shown in Figure 1, includes a blowback pipe 1 installed in the dust collector and a cloth bag 4 located below the blowback pipe. Since the blowback pipe 1 directly blows back against the bag 4, it often causes the bag 4's pocket was blown to pieces. The utility model improves the dust collector structure described in Fig. 1 . As shown in Figure 2, a support plate 5 is horizontally arranged in the dust collector below the blowback pipe 1, and a cloth bag containing hole is arranged on the support plate 5, and the bag opening 4 of the cloth bag is fitted on the surrounding wall of the cloth bag containing hole. The inside of the pocket 4 of the cloth bag is sequentially set with a cylindrical keel frame 3 and a cylindrical protective cover 2 from the outside to the inside. The upper edge of the cloth bag opening is pressed on the edge of the cloth bag containing hole on the support plate 5. With the structure of the utility model, the blowback pipe 1 blows back into the cloth bag 4 through the cylindrical protective sleeve 2. Due to the support and protection of the keel frame 3 and the cylindrical protective sleeve 2, the mouth of the cloth bag 4 can be effectively prevented from being blown. rotten.
