Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a novel off-line dust collector. Background Art

[0002] An offline dust collector is a dust removal device that performs dust cleaning when the equipment is shut down. It is mainly used in situations where high requirements for dust emission control are required, such as heavy industrial production such as steel and cement.

[0003] The offline dust collector uses bag filtration to filter the air through the fine pores of the bag to capture and separate dust particles. In the dust collector, air enters the dust removal chamber through the air inlet duct. After convection, deposition, inertia, collision and other effects, the particles gradually deposit on the bags, and the clean air is discharged through the air outlet duct, ultimately achieving the purpose of purifying the air.

[0004] At present, the offline part of the common offline dust collector on the market will be designed with two special air outlet ducts. The air ducts are connected to the box body. The function of the air ducts is to guide the wind when inducing air. The air ducts will be combined with the box body to form a complete dust collector. One of the two air outlet channels is horizontal and the other is tilted downward. The two are connected, and the air outlet is set at the bottom of the inclined air duct. This design adopts a bottom suction design.

[0005] This design is very regular, but it makes the dust collector larger, taking up a lot of space and materials, and covers a relatively large area. At the same time, the air duct is relatively tortuous, and the bottom suction method has a large wind resistance. At the same time, adding a fan at the air outlet also requires additional pipe connections, which increases material and labor costs, various conventional consumables, transportation costs, wind resistance, and also increases the maintenance workload of workers.

[0006] Therefore, the present application provides a novel off-line dust collector to overcome the defects of the prior art. Utility Model Content

[0007] The utility model aims to solve the problem that the existing off-line dust collector is large in size, occupies a large amount of space and materials, has a relatively tortuous air outlet duct, increases the cost of the manufacturer and the user enterprise, and also increases the maintenance workload of the workers.

[0008] The technical solution of the utility model provides a new type of off-line dust collector, which includes a box body, and the top of the front side wall of the box body is equipped with a horizontally arranged air duct 2. An air outlet is arranged on one side of the air duct 2, and the air outlet is connected to the fan, and the fan is driven by a motor, changing the original bottom suction plus pipeline plus fan structure into a side suction and fan directly connected mode.

[0009] Secondly, the interior of the box is cleverly divided into at least two dust removal chambers. The dust removal chambers are isolated by partitions, and the partitions are tightly fixed to the front and rear inner side walls and the inner top wall of the box to ensure the independence of the dust removal chambers.

[0010] Finally, a ventilation duct is opened in the second air duct. A cylinder is installed on the top of the second air duct, and its output end extends downward. The number of cylinders matches the dust removal chamber, and a horizontally arranged rubber baffle is provided at the air outlet of each dust removal chamber. These rubber baffles are fixedly connected to the corresponding cylinder output ends. Through the telescopic movement of the cylinder, the rubber baffles can be flexibly controlled to control the opening and closing of the ventilation duct, thereby realizing the offline dust removal operation of the dust removal chamber.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a novel offline dust collector, which changes the air suction mode of the device from bottom suction to side suction by setting a horizontal air duct 2 and setting a fan and a motor on one side of the air duct 2, thereby reducing wind resistance, saving space and materials, and reducing the maintenance workload of workers. At the same time, the fan and the motor are installed at a high position at the air outlet, and are directly connected overhead, which saves space and pipelines, reduces wind resistance, improves the dust removal efficiency of the equipment, saves costs, and is also convenient for transportation.

[0019] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below in conjunction with specific diagrams; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the utility model.

[0020] Prior art

[0021] like Figure 1 , Figure 2 As shown: a common dust collector on the market is given, which consists of a box body 1 and an air duct 2. The air duct 2 is fixed on the front side of the box body 1. The air duct 2 consists of a horizontal air duct 21, an inclined air duct 22 and an outer shell. An air outlet 3 is opened at the bottom of the inclined air duct 22, and an induced draft fan is connected to the air outlet 3.

[0022] This design belongs to bottom suction. Under the action of the induced draft fan, the cleaned air first enters the horizontal air duct 21 and then enters the inclined air duct 22. That is to say, the clean air is sucked from the bottom and then discharged to lead the filtered gas in the dust collector. This design is very regular and looks relatively neat in appearance, but this design has great defects. First, the bottom suction method has a large wind resistance, which is not conducive to leading out the clean gas. Secondly, this design adopts a design in which two air ducts are connected, which requires a large amount of materials, increases the manufacturing cost, prolongs the manufacturing time, and also leads to a larger size of the dust collector, which requires a larger space, resulting in an increase in the transportation cost of the dust collector.

[0023] Example

[0024] In order to solve the problems of the existing dust collector, we have made some improvements to the device to overcome some defects of the original equipment. The specific improvements are as follows:

[0025] As attached Figure 3 To Attachment Figure 6 As shown: a novel off-line dust collector comprises a box body 1, a horizontally arranged air duct 2 4 is fixed on the top of the front side wall of the box body 1, the box body 1 is connected with the air duct 2 4, an air outlet 3 is opened on the right side wall of the air duct 2 4, the air outlet 3 is connected with a fan 5, one side of the fan 5 is connected with a motor 6, the motor 6 and the fan 5 are directly connected overhead, and the two work together to absorb clean air from the air duct 2 4 and discharge it, changing the original bottom suction into side suction, and canceling the original inclined air duct 22, reducing wind resistance, reducing the materials required for manufacturing the dust collector, saving costs, reducing the size of the dust collector, making the dust collector more convenient to transport, and reducing the maintenance workload of workers.

[0026] like Figure 5 , Figure 6 As shown: at least two dust removal chambers 9 are arranged in the box body 1, and a partition plate 10 is arranged between each two of the dust removal chambers 9. The partition plate 10 is fixedly connected to the front and rear inner side walls and the inner top wall of the box body 1. Each dust removal chamber 9 can operate independently, and of course, can also be combined and used synchronously.

[0027] A ventilation duct 41 is opened in the air duct 2 4, and the number of the ventilation ducts 41 corresponds to the number of the dust removal chambers 9. One end of the ventilation duct 41 is connected to the air outlet of the dust removal chamber 9, and the other end is connected to the air outlet 3. A cylinder 7 with an output end facing downward is fixed to the top of the air duct 2 4, and the number of the cylinders 7 corresponds to the number of the dust removal chambers 9. A horizontally arranged rubber baffle 8 is fixed to the output end of each of the cylinders 7, and the rubber baffles 8 are respectively arranged directly above the ventilation duct 41.

[0028] When a dust removal chamber 9 needs to be used, the cylinder 7 corresponding to the dust removal chamber 9 is started, and the rubber baffle 8 is driven to rise. The motor 6 and the fan 5 work together to extract the clean air after the dust removal in the dust removal chamber 9 through the air duct 4. When the cylinder 7 drives the rubber baffle 8 to descend and blocks the corresponding ventilation duct 41, the motor 6 and the fan 5 cannot extract air from the dust removal chamber 9, and the dust removal chamber 9 is closed.

[0029] Each cylinder 7 can operate independently or be used in conjunction with each other. Through the unique design of the ventilation duct 41, rubber baffle 8, partition plate 10 and cylinder 7, the device can use a dust removal chamber 9 alone or use multiple dust removal chambers 9 at the same time.

[0030] Working method: Start the cylinder 7 to drive the rubber baffle 8 to rise, start the motor 6 and the fan 5, and the motor 6 and the fan 5 work together to lead the clean air in the dust removal chamber 9 through the air duct 4 and the ventilation duct 41. When the dust removal chamber 9 needs to be closed, the cylinder 7 drives the rubber baffle 8 to descend until the corresponding ventilation duct 41 is blocked.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should fall within the technical scope of the present invention.
