Description

Technical Field

[0001] The utility model belongs to the technical field of dust collector bags, in particular to a corrosion-resistant and high-temperature-resistant dust collector bag. Background Art

[0002] A bag dust collector, also known as a filter dust collector, is a dry and high-efficiency dust collector that uses bag filter elements to capture solid particles in dust-laden gas. It is suitable for capturing fine, dry non-fibrous dust. The filter bags are made of textile filter cloth or non-textile felt, and use the filtering effect of the fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. The use of bag dust collectors has greatly improved the emission of industrial waste gas. However, since bags are consumables, they need to be regularly maintained and replaced after a period of use.

[0003] Based on the above, the inventors have discovered the following problems: bag-type dust collectors are generally used in a large proportion in industrial production, so the dust bags are faced with a high-temperature working environment and corrosion by corrosive gases during use. Therefore, the length of the service life of the dust bags directly affects the cost control of industrial production. In the prior art, the dust bags are generally installed in the porous plate through the rubber ring on the top. However, the rubber ring is prone to aging due to long-term use, and the production specifications of the rubber ring may deviate, which may easily lead to the dust bag and the installation part of the porous plate not fitting together, thereby causing particulate matter to leak out or even the dust bag to fall off.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a corrosion-resistant and high-temperature resistant dust collector bag is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a corrosion-resistant and high-temperature resistant dust collector bag, which is achieved by the following specific technical means:

[0006] The cam is provided with a plurality of first limit blocks, each of which is provided with a plurality of second limit blocks, and the plurality of first limit blocks are provided with a plurality of second limit blocks respectively.

[0007] Furthermore, the height of the first slot gradually decreases from one end to the other end, and there is a raised portion at the end where the height gradually decreases, and the width of the raised portion matches the second limit block.

[0008] Furthermore, the inner edge of the cloth bag base is an arc-shaped structure.

[0009] Furthermore, a spring is installed below the cloth bag base.

[0010] Furthermore, the simple wrench and the second slot are movably mounted.

[0011] Furthermore, the fixing ring is made of metal.

[0012] Furthermore, the base material of the dust bag is polypropylene fiber, and the outside and inside of the dust bag are both coated with fluorocarbon resin.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can realize the rapid installation and fixation of dust bags through the coordinated use of the bag base, the lower fixed base, the simple wrench and the upper fixed cover, and improve the installation air tightness between the dust bags and the porous plate, and improve the stability of the installation joint, so as to ensure the filtering effect of the bag dust collector.

[0015] 2. The utility model uses a bag base and a fixing ring in combination. The inner edge of the bag base is an arc-shaped structure, which can ensure that the outer coating of the bag will not be scratched by the edge of the porous plate when installing the dust bag. The bag base can just support the fixing ring, so that the dust bag will not fall into the filter chamber due to operational errors during installation, which increases the installation time.

[0016] 3. The utility model improves the corrosion resistance and heat resistance of the dust collector bag by using polypropylene fiber, and increases the corrosion resistance and heat resistance of the dust collector bag by adding fluorocarbon resin coating on the inner wall and the outer wall, thereby extending the service life of the dust collector bag and reducing the increase in production costs caused by replacing the dust collector bag.

[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 5 As shown:

[0029] The utility model provides a kind of anti-corrosion and high temperature resistant dust collector bag, comprising a porous plate 1 and a dust collecting bag 2, a lower fixed base 3 is welded on the surface of the porous plate 1, the lower fixed base 3 is a cylindrical hollow structure, four first card slots 4 are equidistantly provided on the top of the inner wall of the lower fixed base 3, a guide slot 5 is provided below each of the four first card slots 4, a bag base 6 is embedded and slidably installed in the lower fixed base 3, four first limit blocks 7 are equidistantly welded on the outer edge of the bag base 6, the four first limit blocks 7 are slidably connected with the four guide slots 5, and the bag base 6, the first limit blocks 7 and the guide slots 5 are arranged to slide. The first limit block 7 is slidably connected with the guide groove 5, so as to ensure the stability of the lateral position of the bag base 6, and thus the installation position of the dust bag 2 can be kept stable. The top of the lower fixed base 3 is snap-fitted with an upper fixed cover 8, and the upper fixed cover 8 is also a cylindrical hollow structure. The top of the upper fixed cover 8 is symmetrically provided with a pair of second slots 9, and a simple wrench 10 is snap-fitted in the second slots 9. Through the coordinated use of the second slots 9 and the simple wrench 10, the upper fixed cover 8 is rotated by twisting the simple wrench 10, so as to realize the installation and removal of the upper fixed cover 8 on the lower fixed base 3, thereby realizing the dust removal. The dust bag 2 can be quickly installed and disassembled to improve the installation efficiency. Four second limit blocks 11 are equidistantly welded on the outer edge of the upper fixed cover 8. The first card slot 4 and the second limit block 11 can be installed in coordination. An annular rubber ring 12 is installed on the bottom end surface of the upper fixed cover 8, and a fixing ring 13 is installed on the top of the dust bag 2. Through the coordinated use of the bag base 6, the upper fixed cover 8, the second limit block 11, the first card slot 4, the annular rubber ring 12 and the fixing ring 13, the second limit block 11 on the upper fixed cover 8 can slide in the first card slot 4, and the height of the first card slot 4 gradually decreases from one end to the other end, thereby achieving the second card slot 4 being pressed down. The limit block 11 has the effect of locking the upper fixed cover 8. At this time, when the fixing ring 13 is installed between the annular rubber ring 12 and the bag base 6, the dust bag 2 can be locked and pressed. A rubber ring is installed on the lower end face of the upper fixed cover 8, and the rubber ring can fit more closely with the surface of the fixing ring 13, thereby ensuring that the dust bag 2 is installed with good air tightness and preventing waste gas generated by industrial production from escaping from the joint surface of the two. The size of the bag base 6 can just support the fixing ring 13, thereby ensuring that during the installation of the dust bag 2, the dust bag 2 will not fall into the filter chamber due to staff errors, thereby reducing the installation efficiency.

[0030] Furthermore, the height of the first slot 4 gradually decreases from one end to the other end, and the end with the lower height has a protrusion of a certain height, and the width of the protrusion is matched with the second limit block 11. Through the coordinated use of the protrusion and the second limit block 11, when the upper fixed cover 8 is rotated, the second limit block 11 gradually moves from one end of the first slot 4 to the protrusion. Under the action of the bottom bag base 6 and the spring 14, the second limit block 11 can be engaged with the protrusion, thereby achieving the effect of fixing the upper fixed cover 8, thereby ensuring the installation reliability of the dust bag 2.

[0031] Furthermore, the inner edge of the bag base 6 is an arc-shaped structure. By setting the inner edge of the bag base 6 to an arc-shaped structure, it is ensured that when the staff installs the dust bag 2, there is no need to install a protective device on the porous plate 1 to ensure that the coating attached to the surface of the dust bag 2 will not be scratched by the edge of the porous plate 1 during the installation process, thereby ensuring the quality and efficiency of the installation of the dust bag 2.

[0032] Furthermore, a spring 14 is installed under the bag base 6. Through the coordinated use of the bag base 6 and the spring 14, the bag base 6 can have sufficient supporting force upwards, so that the bag base 6 and the upper fixing cover 8 can clamp the fixing ring 13, and the bag base 6 can press the upper fixing cover 8 upwards, so that the second limit block 11 on the upper fixing cover 8 can be engaged in the raised part at one end of the first slot 4, ensuring that the upper fixing cover 8 will not loosen, thereby improving the reliability of the installation of the upper fixing cover 8. When the upper fixing cover 8 needs to be removed, the upper fixing cover 8 can be removed by pressing downward and rotating it, thereby realizing the rapid disassembly of the upper fixing cover 8 and improving the efficiency of subsequent replacement of the dust bag 2.

[0033] Furthermore, the simple wrench 10 and the second slot 9 are movably installed rather than fixedly installed. Through the coordinated use of the simple wrench 10 and the second slot 9, the upper fixed cover 8 can be removed more conveniently. The movability of the two reduces the production cost of the upper movable cover and also facilitates the subsequent frame installation.

[0034] Furthermore, the fixing ring 13 is made of metal, which ensures that the dust bag 2 is more securely connected to the fixed part of the porous plate 1, thereby preventing the dust bag 2 from falling from the porous plate 1 due to aging of the connection part.

[0035] Furthermore, the base material of the dust bag 2 is polypropylene fiber, and the outside and inside of the dust bag 2 are both provided with a fluorocarbon resin coating 15. The polypropylene fiber has high corrosion resistance, wear resistance and heat resistance, and the fluorocarbon resin coating 15 also has certain corrosion resistance and wear resistance. By attaching the fluorocarbon resin coating 15 to the inner and outer surfaces of the dust bag 2, the service life of the dust bag 2 is further improved, and the replacement cycle of the dust bag 2 is extended, thereby reducing the production cost.

[0036] The specific usage and function of this embodiment are as follows:

[0037] First, pass the dust bag 2 into the filter chamber from the lower fixed base 3. When the dust bag 2 is fully installed in the filter chamber, install the fixing ring 13 on the dust bag 2 on the bag base 6 and make the two fit completely. At this time, cover the upper fixing cover 8, insert the two ends of the simple wrench 10 into the second limit block 11, and rotate the upper fixing cover 8. When it is rotated into place and the sound of the second limit block 11 being stuck in the raised part of the first slot 4 is heard, the upper fixing cover 8 is locked. At this time, remove the simple wrench 10 to complete the installation. The above steps can quickly complete the installation of the dust bag 2, improve the air tightness and installation reliability of the joint between the dust bag 2 and the porous plate 1, and by attaching anti-corrosion and high-temperature resistant materials on the surface of the dust bag 2, the service life of the dust bag 2 is increased and the use cost is reduced.

[0038] The implementation modes of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
