Description

Technical Field

[0001] This utility model relates to the technical field of fastening and adjusting mechanisms, specifically to the filter fastening and adjusting mechanism of a bag filter dust collector. Background Technology

[0002] Baghouse dust collectors are a type of high-efficiency dust removal equipment, widely used in dust control in industrial production. Their core working principle is to filter dust-laden gas through filter bags, causing the dust to adhere to the surface of the filter bags, thereby achieving gas-solid separation.

[0003] For example, the patent with announcement number CN204219936U (a bag filter): includes a shell and a dust filtration device. The dust filtration device includes several frames and several filter bags for dust filtration, which are respectively fitted outside the frames. The frames are all fixedly connected to a tube sheet provided inside the shell. At the end of the frame away from the tube sheet, a baffle plate with an outer diameter equal to or greater than the outer diameter of the bottom of the filter bag is fixedly provided. A gap for air to pass through is formed between the adjacent baffle plates.

[0004] While the aforementioned existing technologies prevent the bottom of the filter bag from rupturing due to prolonged impact from high-speed airflow, traditional baghouse dust collectors often use simple bolt and nut fastening or spring compression methods for filter fastening. After prolonged use, the bolts are prone to loosening, leading to poor bag sealing. Although the spring compression method is relatively convenient to install, its elastic coefficient is fixed and cannot be adjusted according to actual working conditions and bag deformation, resulting in poor practicality. Therefore, there is an urgent market need to develop a filter fastening adjustment mechanism for baghouse dust collectors to help solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a filter fastening adjustment mechanism for bag filters, so as to solve the problem mentioned in the background art that the filter fastening of traditional bag filters often adopts simple bolt and nut fastening or spring compression methods, which are not practical.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter fastening and adjustment mechanism for a bag filter dust collector, including a tube sheet. The tube sheet has a through hole inside, and an outer ring groove is provided above the outer side of the through hole inside the tube sheet, communicating with the through hole.

The bag opening ring edge is located inside the outer ring groove. A frame mounting plate is provided above the bag opening ring edge, and the frame mounting plate is annular. A fastener is provided above the frame mounting plate, and the fastener includes a lower pressure plate, an upper pressure plate, and a rubber ring. The rubber ring is fixedly installed above the lower pressure plate, and the upper pressure plate is fixedly installed above the rubber ring. Both the lower and upper pressure plates are annular.

[0007] Preferably, a detection groove is provided on the lower end surface of the lower pressure plate, and a pressure sensor is provided inside the detection groove.

[0009] Preferably, guide columns are symmetrically fixedly installed on both sides above the lifting pressure plate, the upper end of the guide column slides into the interior of the mounting plate, and a limiting piece is fixedly installed above the guide column.

[0010] Preferably, the bag has an internal frame, which includes fixing rings and vertical rods. Multiple fixing rings are provided and arranged vertically at intervals.

[0011] Preferably, four vertical rods are provided, and the four vertical rods are arranged in a ring outside the fixing ring, and the vertical rods are fixedly connected to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the combination of a lower pressure plate, a rubber ring, and an upper pressure plate, utilizes the elastic buffering effect of the rubber ring to effectively avoid damage to the filter bag caused by rigid compression as in traditional methods.

[0014] 2. This utility model, through the setting of a pressure sensor, can measure the pressure of the lower pressure plate on the frame mounting plate in real time, thereby reflecting the degree of compression of the filter bag. This allows operators to monitor the working status of the filter bag at any time, making it easier to adjust the degree of compression of the filter bag, ensuring that the filter bag is always in the best sealing state, and improving filtration efficiency and dust removal effect.

[0015] 3. This utility model, through the setting of an electric cylinder, can drive the fastener to move up and down, improving adjustment efficiency and accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-3 This utility model provides an embodiment of a filter fastening and adjustment mechanism for a bag filter dust collector, comprising a tube sheet 1, with a through hole 101 inside the tube sheet 1, and an outer ring groove 102 above the outer side of the through hole 101 inside the tube sheet 1, the outer ring groove 102 communicating with the through hole 101. A filter bag 2 is disposed inside the through hole 101 of the tube sheet 1, the filter bag 2 comprising a bag body 201 and a bag opening ring edge 202, the bag body 201 and the bag opening ring edge 202 being sewn together, the bag opening ring edge 202 being located on the outer side. Inside the annular groove 102, a skeleton mounting plate 10 is provided above the bag opening annular edge 202, and the skeleton mounting plate 10 is set as an annular plate. A fastener 3 is provided above the skeleton mounting plate 10. The fastener 3 includes a lower pressure plate 301, an upper pressure plate 302 and a rubber ring 303. The rubber ring 303 is fixedly installed above the lower pressure plate 301, and the upper pressure plate 302 is fixedly installed above the rubber ring 303. Both the lower pressure plate 301 and the upper pressure plate 302 are set as annular plates.

[0022] By utilizing the elastic buffering effect of the rubber ring 303, damage to the cloth bag 2 caused by rigid compression as in traditional methods can be effectively avoided. It can also better adapt to the slight deformation of the cloth bag 2 during operation. Furthermore, the bag opening ring edge 202 of the cloth bag 2 can be pressed down and tightened by driving the fastener 3 to move down. The degree of compression can be adjusted according to the actual working conditions to ensure that the cloth bag is always in a good sealing state, thus increasing its practicality.

[0023] Furthermore, a detection groove is provided on the lower end surface of the lower pressure plate 301, and a pressure sensor 11 is provided inside the detection groove. The lower pressure plate 301 is fixedly connected to the pressure sensor 11. The pressure sensor 11 is a DBSL pressure sensor, and the measuring end of the pressure sensor 11 is in contact with the skeleton mounting plate 10.

[0024] The pressure sensor 11 can measure the pressure of the lower pressure plate 301 on the frame mounting plate 10 in real time, thereby reflecting the degree of compression of the filter bag. This allows operators to monitor the working status of the filter bag at any time, making it easier to adjust the compression of the filter bag and ensure that the filter bag is always in the best sealing state, improving filtration efficiency and dust removal effect. At the same time, in terms of protection, when the pressure exceeds the set range, the pressure sensor 11 can detect it in time, which helps operators take measures to avoid damage to the filter bag due to excessive compression and extend the service life of the filter bag and equipment.

[0025] Furthermore, a lifting pressure plate 4 is provided above the fastener 3. The lifting pressure plate 4 is fixedly connected to the upper pressure plate 302. An mounting plate 5 is provided above the lifting pressure plate 4. An electric cylinder 6 is fixedly installed inside the mounting plate 5. The push rod end of the electric cylinder 6 slides to the bottom of the mounting plate 5 and is fixedly connected to the lifting pressure plate 4.

[0026] The electric cylinder 6 can drive the fastener 3 to move up and down, improving adjustment efficiency and accuracy, and increasing practicality.

[0027] Furthermore, guide posts 7 are symmetrically fixedly installed on both sides above the lifting pressure plate 4. The upper end of the guide post 7 slides into the interior of the mounting plate 5, and a limit piece 8 is fixedly installed above the guide post 7.

[0028] The guide column 7 ensures the stability and straightness of the lifting pressure plate 4 during its up-and-down movement, preventing it from shifting or swaying, thus increasing its practicality.

[0029] Furthermore, the bag 2 has an internal frame 9, which includes fixing rings 901 and vertical rods 902. Multiple fixing rings 901 are provided and arranged vertically at intervals. Four vertical rods 902 are provided and arranged in a ring outside the fixing rings 901. The vertical rods 902 are fixedly connected to each other.

[0030] The frame 9 provides good support for the bag 2, enabling the bag 2 to maintain a certain shape and stability, which is beneficial to the filtration work of the bag 2 and increases its practicality.

[0031] Working principle: During use, the electric cylinder 6 drives the lifting pressure plate 4 to move, and the lifting pressure plate 4 drives the fastener 3 to move down. Utilizing the elastic buffering effect of the rubber ring 303, the bag opening ring edge 202 of the filter bag 2 is pressed down and tightened, avoiding damage to the filter bag caused by rigid compression, and can adapt to the slight deformation of the filter bag during operation. The pressure sensor 11 on the lower end face of the lower pressure plate 301 measures the pressure of the lower pressure plate 301 on the skeleton mounting plate 10 in real time, reflecting the degree of compression of the filter bag. The operator can monitor the working status of the filter bag at any time and adjust the degree of compression, which is conducive to the filter bag being in the best sealing state. The skeleton 9 inside the filter bag 2 includes multiple vertically spaced fixing rings 901 and four vertical rods 902 arranged in a ring outside the fixing rings 901, which provide good support for the filter bag 2, maintain its shape and stability, and are beneficial to the filtration work.
