Description

Technical Field

[0001] The utility model relates to the technical field of pulse bag dust collector devices, in particular to a pulse bag dust collector which is easy to clean. Background Art

[0002] The pulse bag dust collector is a new type of high-efficiency pulse bag dust collector improved on the basis of the bag dust collector. In order to further improve the pulse bag dust collector, the modified pulse bag dust collector retains the advantages of high purification efficiency, large gas processing capacity, stable performance, easy operation, long filter bag life, and small maintenance workload.

[0003] When filtering some oily gases, the dust in the oily gas has a certain degree of stickiness. When the dust passes through the ash hopper, the probability of the dust adhering to the inner surface of the ash hopper will increase. At the same time, the sticky dust is not easy to clean. However, in the traditional way, when using a scraper to clean the ash hopper, due to the curved surface of the ash hopper, some dust will always adhere to the ash hopper. When the dust dries, it will completely adhere to the ash hopper, increasing the difficulty of cleaning.

[0004] In view of the existing situation, most of the ash hoppers are cleaned by disassembling the ash hopper and then reinstalling it; however, no optimization has been proposed for the cleaning of the air inlet. Although the air inlet is currently set on the ash hopper and disassembled and cleaned simultaneously with the ash hopper, due to the bent end formed between the air inlet and the ash hopper and the inconvenience in clearing the dirt, some cleaning dead corners will appear, causing certain effects after long-term accumulation.

[0005] In view of the above, the present application proposes a pulse bag dust collector that is easy to clean to solve the problem, and the structure of the air inlet end is set to a detachable design to increase the convenience during cleaning. Utility Model Content

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0032] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In the prior art, the air inlet of most pulse bag dust collectors is set on the upper side of the equipment surface. The air inlet may need to be cleaned more frequently during use; but since the air inlet is located at the top, a ladder or platform may be needed to reach the top during cleaning, which increases the complexity of operation and safety risks; thus, the present application solves this problem and proposes a pulse bag dust collector that is easy to clean, as follows:

[0034] For reference Figure 1-2 The present application is mainly composed of a working area 1, a ash hopper 2 detachably arranged at the bottom of the working area 1, and an air intake piece 3 connected to the middle part of the connection between the ash hopper 2 and the working area 1; through the effect of its connection, it not only provides assistance in setting the height of the air inlet of the working area 1, but also can better disassemble the air intake piece 3 for subsequent cleaning work.

[0035] For reference Figure 1-2 The working area 1 captures and filters the dust and solid particles in the air through a bag collector; its specific structure is similar to that of the existing pulse bag dust collector, and this application will not elaborate on it.

[0036] For reference Figure 1-2The ash hopper 2 is arranged at the bottom of the working area 1 to collect and store dust and powder collected from the bag filter; the ash hopper 2 is detachably connected to the working area 1; the specific connection form is not limited, and can be a threaded connection, a flange connection, etc.

[0037] For reference Figure 1-2 Although the ash hopper 2 is connected to the working area 1 in a detachable manner to facilitate cleaning, the cleaning effect of the air inlet part set in the ash hopper 2 is increased, but because of the turning arc, it is still difficult to clean. In order to further solve this problem, an air inlet part 3 is set in the middle of the connection between the ash hopper 2 and the working area 1; by setting a detachable connection at the air inlet part at the ash hopper 2, and when connecting, the stability of the connection between the ash hopper 2 and the working area 1 can also be relatively increased.

[0038] The air intake member 3 includes a fixed shaft 31, an insert shaft 32 and an air intake shaft 33;

[0039] The fixed shaft 31 mainly serves the purpose of connection and positioning. By stably connecting with the ash hopper 2 and the working area 1, the plug shaft 32 and the air intake shaft 33 are firmly supported. The fixed shaft 31 is specifically arranged at the connection between the ash hopper 2 and the working area 1, and is wrapped on the surface of the ash hopper 2 and the working area 1. The fixed shaft 31 includes two arc plates 311 and two clamping plates 312. The two arc plates 311 are symmetrically arranged and connected and fixed at the symmetrical connection by bolts. The two arc plates 311 are clamped and fixed on the working area 1. The bottoms of the two arc plates 311 are respectively connected to a clamping plate 312, and the shape of the clamping plate 312 is adapted to the setting of the top of the ash hopper 2, so that the clamping plate 312 and the ash hopper 2 are mutually clamped to increase stability.

[0040] For reference Figure 3 , further illustrating that the two ends of the top of the ash hopper 2 protrude outward to form an outward expansion shaft 11, and when the outward expansion shaft 11 is installed on the clamping plate 312, it forms a clamping state with the clamping plate 312, thereby further reducing the downward movement of the fixed shaft 31; and in order to further deepen the fixing effect of the fixed shaft 31, bolts are provided on the two arc plates 311, and the arc plates 311 are fixedly connected to the outer surface of the working area 1 by the bolts.

[0041] The plug shaft 32 serves to connect the air intake shaft 33 and the ash hopper 2. The top of the plug shaft 32 is clamped with the fixed shaft 31, and a bolt is provided on the top of the plug shaft 32, through which the plug shaft 32 is fastened to the bottom of the fixed shaft 31, and the bottom of the plug shaft 32 is inserted into the ash hopper 2 and is connected with the inner cavity of the ash hopper 2; in order to limit the insertion distance of the plug shaft 32 into the ash hopper 2 when inserting, the insertion end of the plug shaft 32 is set to a convex shape, and a relative shape is set in the inner cavity of the ash hopper 2 to limit the plug shaft 32; and further for stability after insertion, an inclined plate 321 adapted to the outer surface of the ash hopper 2 is provided at the bottom of the plug shaft 32 extending outward, when the plug shaft 32 is inserted to the limited position, the inclined plate 321 also fits on the surface of the ash hopper 2, and then the inclined plate 321 is connected to the ash hopper 2 by bolts to increase the overall stability of the plug shaft 32.

[0042] By setting the plug shaft 32, the air inlet shaft 33 is not directly connected to the ash hopper 2. After disassembly, it can be more convenient to do cleaning work. Secondly, when dirt that is difficult to clean appears, the new plug shaft 32 can be directly replaced for use.

[0043] The air intake shaft 33 is used to connect industrial waste gas or air. The air intake shaft 33 is detachably arranged at the end of the plug shaft 32 away from the ash hopper 2 and is connected to the conveying channel 12 arranged inside the plug shaft 32; its detachable setting is based on the convenience of installation of the air intake shaft 33. In terms of connection, it is possible to better select an air intake shaft 33 of a more suitable size to connect to the outside, thereby introducing industrial waste gas or air.

[0044] It is also more convenient to clean after disassembly, because the air is introduced from the air inlet shaft 33, so the dirt accumulated at the inlet port is relatively more. Cleaning the air inlet shaft 33 separately after disassembly can increase the cleaning effect.

[0045] Among them, the ash hopper 2 is symmetrically provided with a plug shaft 32 at one end thereof and is provided with a channel opening 4. The design of the channel opening 4 includes a pretreatment device, such as a cyclone separator or a primary filter, which is used to pre-separate large particles or coarse pollutants; subsequently, the pretreated industrial waste gas or air enters the working area 1 for treatment, and finally the clean air is discharged from the air outlet 5. The specific principles and connection mechanisms are relatively mature existing technologies, and this application will not go into details one by one.

[0046] In the utility model, the working steps of the device are as follows:

[0047] 1. First, clamp the clamping plate 312 and the ash hopper 2. After clamping, the fixed shaft 31 on the top of the clamping plate 312 is symmetrically connected and fixed by bolts at the connection end. Subsequently, bolts are set again in the middle of the fixed shaft 31 to increase the stability of the overall connection;

[0048] 2. Secondly, insert the bottom of the plug shaft 32 into the opening of one end of the ash hopper 2 for connecting the air intake, and insert the distance until it reaches the limit. At this time, the top of the plug shaft 32 will also be clamped with the clamping plate 312. After clamping, the top position of the plug shaft 32 and the clamping plate 312 are connected by bolts. After that, the oblique plate 321 at the bottom of the plug shaft 32 fits on the surface of the ash hopper 2, and bolts are set on the surface to fasten the oblique plate 321 to the surface of the ash hopper 2, completing the fixing effect of the plug shaft 32;

[0049] 3. Then, connect and install the air intake shaft 33 at the delivery channel 12 set at the bottom of the plug shaft 32. According to the external environment, select the air intake shaft 33 of the most suitable size and install it on the plug shaft 32 to form a connection with the delivery channel 12;

[0050] 4. Finally, industrial waste gas or air is introduced from the air inlet shaft 33 for work, and after being pre-treated by the design of the channel opening, it enters the working area 1 for treatment, and finally the clean gas is discharged from the air outlet 5.

[0051] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
