Description

Cloth bag replacement tool of cloth bag dust remover

Technical Field

The utility model relates to a bag-type dust remover, in particular to a bag-type replacement tool of the bag-type dust remover.

Background

The bag-type dust collector is a dry dust filtering device. After a period of use, a layer of dust is accumulated on the surface of a cloth bag of the cloth bag dust collector due to the effects of screening, collision, retention, diffusion, static electricity and the like, the layer of dust is called a primary layer, the primary layer forms a main filtering layer in the later movement process, and dust particles with larger meshes can also obtain higher filtering efficiency by virtue of the action of the primary layer. With the accumulation of dust on the surface of the cloth bag, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference on the two sides of the cloth bag is very large, some tiny dust particles attached to the cloth bag are extruded to pass, so that the efficiency of the dust remover is reduced. In addition, the air quantity of the dust removing system is obviously reduced due to the excessively high resistance of the dust remover. Therefore, when the resistance of the dust remover reaches a certain value, ash is removed or a new cloth bag is replaced in time.

However, after dust is deposited on the surface and inside of the cloth bag, the weight of the cloth bag and the keel plus the weight of the dust reaches more than tens of kilograms, and the difficulty of cloth bag replacement operation is increased. When the existing cloth bag is replaced, an operator needs to use a self-made iron hook to lift the cloth bag keel and the cloth bag up hard, and after the cloth bag reaches a certain height, the old cloth bag is detached, and then a new cloth bag is sleeved. The whole cloth bag replacement operation process has low efficiency and high labor intensity, and the operation safety risk caused by the heavy weight is high.

Disclosure of Invention

The utility model aims to provide a cloth bag replacing tool of a cloth bag dust remover, which is used for reducing difficulty of cloth bag replacing operation, accelerating working efficiency and protecting personal safety of operators.

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a top plan view of the construction of the lifting appliance of FIG. 1;

FIG. 3 is a front elevational view of the construction of the lifting appliance of FIG. 1;

in the figure, a 1-supporting platform, a 2-supporting leg, a 21-telescopic rod, a 22-telescopic sleeve, a 3-threaded sleeve, a 4-driving screw, a 5-lifting sling, a 51-lifting disc, a 52-lifting hook, a 521-limiting flange, a 522-hook part, a 6-rotating rod and a 7-spring are arranged.

Detailed Description

The utility model is further explained below with reference to the drawing and the specific embodiments.

As shown in fig. 1-3, the cloth bag replacing tool of the cloth bag dust remover comprises a supporting platform 1, wherein three supporting legs 2 are uniformly hinged to the peripheral edge of the supporting platform 1 along the circumferential direction, the length of each supporting leg is 1-2 m, and the bottoms of the supporting legs 2 are connected with each other through a chain; the middle part of the supporting platform 1 is integrally formed and provided with a threaded sleeve 3, a transmission screw 4 is screwed in the threaded sleeve 3, a rotating rod 6 is arranged on the top of the transmission screw 4 in a penetrating way, and a lifting sling 5 for lifting a bag keel is rotatably connected to a non-threaded section at the bottom of the transmission screw 4;

the lifting sling 5 comprises a hanging scaffold 51 and a lifting hook 52, the hanging scaffold 51 is rotationally connected with the transmission screw 4 through a tapered roller bearing, a plurality of connecting holes are uniformly formed in the circumferential edge of the hanging scaffold 51, the lifting hook 52 is inserted into the connecting holes, and a spring 7 is connected between the bottom of the connecting hole and the lifting hook 52; the hook 52 is L-shaped and has a limit flange 521 provided at one end thereof located in the coupling hole and a hook 522 protruding outward at the other end thereof.
