Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust storage bin of a bag filter. Background Art

[0002] A bag filter is a dry dust filtering device, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag filter, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the dust storage bin at the bottom. When the gas containing finer dust passes through the filter bag, the dust is retained outside the filter bag, so that the gas is purified.

[0003] After the bag dust removal device is used for a long time, a large amount of dust will be collected in the dust storage bin, and the ash discharge operation needs to be carried out in time. The commonly used dust storage bin generally has a hopper shape, and an ash discharge valve is arranged at the lower end. When carrying out the ash discharge operation, the valve is opened, and then the dust is discharged downward by its own weight. However, in this ash discharge method, the phenomenon of ash discharge port congestion often occurs, affecting the ash discharge efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust storage bin of a bag filter, which is used to solve the problem that the dust storage bin at the bottom of the existing bag dust removal device is prone to poor ash discharge.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a dust storage bin of a bag filter, including a hopper and a support frame fixed to the outer edge of the top of the hopper. The discharge housing includes a bottom housing connected to the bottom end of the hopper, a horizontal cylinder connected to one side of the bottom housing, and a vertical cylinder connected to the bottom of the outer end of the horizontal cylinder. The spiral blade shaft is rotatably installed in the inner cavities of the bottom housing and the horizontal cylinder. The motor is used to drive the spiral blade shaft to rotate. The discharge port assembly is slidably sleeved on the bottom end of the vertical cylinder and is used to adjust the opening and closing of the bottom outlet of the vertical cylinder. The telescopic cylinder is used to drive the discharge port assembly to move up and down.

[0006] Preferably, an end cover is fixedly connected to the outer end of the horizontal cylinder, a shaft sleeve matched with the outer end of the spiral blade shaft in a rotational socket manner is arranged in the middle of the end cover, and a shaft hole matched with the inner end of the spiral blade shaft in a rotational socket manner is arranged in the middle of the inner side wall of the bottom housing.

[0007] Preferably, the motor is fixed on the outer side wall of the end cover, and the power output shaft of the motor is fixedly butted with the outer end of the spiral blade shaft.

[0008] Preferably, the discharge port assembly includes a sleeve slidably connected to the bottom end of the vertical cylinder and a slide groove with the top end fixed to the bottom end of the outer wall of the sleeve, and the discharge port is opened on the side wall of the sleeve at a position corresponding to the slide groove.

[0009] Preferably, a support plate extending laterally is fixed to the other side of the bottom end of the sleeve, a lower ear seat hinged to the bottom end of the telescopic cylinder piston rod is fixed to the top surface of the support plate, and an upper ear seat hinged to the top end of the telescopic cylinder piston rod is fixed to the bottom of the horizontal cylinder body opposite to the lower ear seat.

[0010] Preferably, the top end of the bottom shell body is sewn and connected to the bottom end of the ash hopper by bolts, and the outer end of the horizontal cylinder is fixedly connected to the outer edge of the end cover by a flange.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model relates to a dust bag collector in which the ash storage bin is used. When in use, the lifting of a sleeve is used to control the opening and closing of the opening at the bottom end of the vertical cylinder. When discharging ash, a motor drives the spiral blade shaft to transfer the dust stored in the ash hopper to the outside and discharge it from the opening at the bottom end of the vertical cylinder, which effectively solves the problem of poor ash discharge in the ash storage bin at the bottom of the bag dust collector.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , the present utility model provides a technical solution: a dust storage bin of a bag filter, including a dust hopper 1 and a support frame 2 fixed to the outer edge of the top end of the dust hopper 1. The top end of the dust hopper 1 is connected to the main bin body of the bag filter. The bags provided in the main bin body are used to intercept dust particles in the dust-containing gas, and the intercepted dust particles fall off and accumulate in the dust hopper 1.

[0025] The discharge housing 3 includes a bottom housing 3.1 connected to the bottom end of the dust hopper 1, a horizontally arranged cylinder 3.2 connected to one side of the bottom housing 3.1, and a vertical cylinder 3.5 connected to the bottom of the outer end of the horizontally arranged cylinder 3.2; the spiral blade shaft 4 is rotatably installed in the inner cavities of the bottom housing 3.1 and the horizontally arranged cylinder 3.2. Among them, the outer end of the horizontally arranged cylinder 3.2 is fixedly connected with an end cover 3.3. The middle of the end cover 3.3 is provided with a shaft sleeve 3.4 rotatably sleeved with the outer end of the spiral blade shaft 4, and the middle of the inner side wall of the bottom housing 3.1 is provided with a shaft hole 3.1.1 rotatably sleeved with the inner end of the spiral blade shaft 4. The top end of the bottom housing 3.1 and the bottom end of the dust hopper 1 are connected by bolts, and the outer end of the horizontally arranged cylinder 3.2 is fixedly connected to the outer edge of the end cover 3.3 through a flange.

[0026] The motor 5 is used to drive the rotation of the spiral blade shaft 4. Among them, the motor 5 is fixed on the outer side wall of the end cover 3.3, and the power output shaft of the motor 5 is fixedly butted with the outer end of the spiral blade shaft 4.

[0027] The discharge port assembly 6 is slidably sleeved on the bottom end of the vertical cylinder 3.5 and is used to adjust the opening and closing of the bottom outlet of the vertical cylinder 3.5. The telescopic cylinder 7 is used to drive the discharge port assembly 6 to move up and down. Among them, the discharge port assembly 6 includes a sleeve 6.1 slidably sleeved with the bottom end of the vertical cylinder 3.5 and a chute 6.2 fixed to the bottom end of the outer side wall of the sleeve 6.1. The side wall of the sleeve 6.1 is provided with a discharge port 6.1.1 corresponding to the position of the chute 6.2. The other side of the bottom end of the sleeve 6.1 is fixed with a horizontally extending support plate 6.3.

The position of the bottom of the horizontally arranged cylinder 3.2 directly opposite to the lower ear seat 6.4 is fixed with an upper ear seat 3.6 hinged to the top end of the piston cylinder of the telescopic cylinder 7. The chute 6.2 is in a state where the outer end is inclined downward.

[0028] In summary, when it is necessary to discharge the dust stored in the hopper 1, the telescopic cylinder 7 extends the piston rod, and the extended piston rod pushes the sleeve 6.1 downward through the support plate 6.3. The sleeve 6.1 is sleeved downward relative to the vertical cylinder 3.5 until the discharge port 6.1.1 is lower than the bottom end of the vertical cylinder 3.5.

[0029] Subsequently, the motor 5 drives the spiral blade shaft 4 to rotate. The rotating spiral blade shaft 4 continuously stirs and pushes outward the dust at the bottom of the inner cavity of the hopper 1. The dust pushed outward flows downward through the vertical cylinder 3.5 and is discharged outside through the discharge port 6.1.1 and the chute 6.2. Among them, in order to further improve the discharge fluency at the bottom end of the vertical cylinder 3.5, a columnar member with an inclined middle surface at the top is arranged vertically in the middle of the bottom surface of the inner cavity of the sleeve 6.1. When the sleeve 6.1 rises, the columnar member just inserts into the bottom of the inner cavity of the vertical cylinder 3.5, and it is ensured that the bottom end of the inclined surface at the top of the columnar member is aligned with the discharge port 6.1.1.
