Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a cloth bag frame for a dust collector that can be quickly assembled and disassembled. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation, maintenance costs, service life, and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production. In the production process of dust collectors, the dust collector bag frame is one of its important components.

[0003] The existing frame of the bag filter is directly fixed on the filter by screw thread, which is inconvenient to install and remove during use, and the frame may fall off. In addition, there are also sealed bayonet frames on the market, but since they are sealed by the inner hole, dust will enter the seal of the inner hole after long-term use, causing blockage and making it difficult to remove the frame. Summary of the invention

[0004] The utility model aims to provide a dust collector bag frame for quick assembly and disassembly to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick loading and unloading dust collector bag frame, comprising a fixed surface 8 and a bag frame 10, the bag frame 10 is arranged below the fixed surface 8, and is characterized in that: a centering cylinder 3 is provided above the fixed surface 8, and the outer ring of the centering cylinder 3 is sleeved with an upper and lower sliding rotating surface 1, and a compression spring 2 is provided between the rotating surface 1 and the fixed surface 8; the outer rings of the fixed surface 8 and the rotating surface 1 are provided with a fixing groove 7, the bottom of the fixing groove 7 is a supporting surface 9, and the upper end surface is provided with four evenly divided clamping tables 5.

[0006] Preferably, a positioning hemisphere 6 is provided below the card table 5 .

[0007] Preferably, a positioning groove 12 cooperating with the positioning hemisphere 6 is provided on the rotating surface 1 .

[0008] Preferably, the fixed surface 8 and the rotating surface 1 are both provided with four equally divided loading and unloading notches 11 .

[0009] Preferably, a retaining ring 4 is provided above the rotating surface 1 and is connected and fixed to the centering cylinder 3 .

[0010] Compared with the prior art, the utility model has the following beneficial effects: first, it has no bolt fixation and can realize quick assembly and disassembly; second, it is provided with upper and lower spring mechanisms and can be easily disassembled even if it is blocked; third, it has a simple structure, low manufacturing cost and good performance.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides a technical solution: a quick-loading and unloading dust collector bag frame, comprising a fixed surface 8 and a bag frame 10, the bag frame 10 is arranged below the fixed surface 8, and is characterized in that a centering cylinder 3 is arranged above the fixed surface 8, and the outer ring of the centering cylinder 3 is sleeved with an up and down sliding rotating surface 1, a compression spring 2 is arranged between the rotating surface 1 and the fixed surface 8, and the rotating surface 1 can move up and down along the centering cylinder 3 and can rotate around the centering cylinder 3.

[0016] The outer circles of the fixed surface 8 and the rotating surface 1 are provided with fixed grooves 7, the bottom of the fixed groove 7 is a supporting surface 9, the upper end surface is provided with four evenly divided clamping tables 5, and positioning hemispheres 6 are provided under the clamping tables 5; a positioning groove 12 cooperating with the positioning hemisphere 6 is provided on the rotating surface 1; the fixed surface 8 and the rotating surface 1 are both provided with four evenly divided loading and unloading notches 11.

[0017] When installing, the loading and unloading notches 11 on the fixed surface 8 and the rotating surface 1 are placed into the fixed groove 7 facing the card table 5, and then the rotating surface 1 is pressed to sink below the card table 5, and the rotating surface 1 is rotated to enter the bottom of the card table 5, so that the positioning hemisphere 6 cooperates with the positioning groove 12, and the compression spring 2 below will always provide an upward force for the rotating surface 1, so that the rotating surface 1 fits with the card table 5 to prevent the cloth bag frame 10 from loosening.
