Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to an antistatic polyester mixed conductive fiber dust removal filter bag. Background Art

[0002] Dust filter bags, also called dust cloth bags, are important components of bag dust collectors. The use of dust filter bags directly affects the dust removal effect and the service life of the equipment. Therefore, dust filter bags require extra attention during installation and use. At the same time, dust filter bags of different materials, precision and temperature resistance need to be matched according to actual working conditions.

[0003] However, when the existing dust filter bag is installed on the flower plate, the spring ring of the filter bag lining is usually stuck in the corresponding circular hole of the flower plate, and the groove on the outer periphery of the filter bag spring ring needs to be fitted with the flower plate hole. However, since it is impossible to confirm whether the spring ring is locked in the circular hole, the filter bag is easily installed too loosely or too tightly when it is installed through the spring ring, thereby affecting the filtering effect of the filter bag. In addition, when the existing dust filter bag is cleaned, since the filter bag is usually made of chemical fiber material, static electricity is easily generated on the surface. When the dust is intercepted by the filter bag, it is easily adsorbed on the outer surface of the filter bag by static electricity and is not easy to fall into the ash hopper, resulting in greater difficulty in cleaning the dust on the surface of the filter bag. Utility Model Content

[0004] The purpose of the utility model is to provide an antistatic polyester mixed conductive fiber dust removal filter bag to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an antistatic polyester mixed conductive fiber dust removal filter bag, comprising a filter bag body, the top of the filter bag body is fixedly connected to a ring, the outer wall of the ring is provided with an outer groove, the inner wall of the ring is movably connected to a spring ring, the inner wall of the spring ring is provided with an inner groove, the interior of the inner groove is provided with four arc bars, a skeleton is embedded in the interior of the filter bag body, the outer wall of the filter bag body is fixedly connected to a conductive fiber layer, the outside of the conductive fiber layer is provided with a movable bar, the bottom end of the filter bag body is fixedly connected to a base cloth, and the inner wall of the filter bag body is fixedly connected to a polyester layer.

[0006] Preferably, a connecting rod is movably passed through the middle of the arc strip, and both ends of the connecting rod are fixedly connected to the top and bottom of the inner groove respectively.

[0007] Preferably, the arc strip is movably connected to the inner groove through a connecting rod.

[0008] Preferably, a top ring is fixedly connected to the top of the skeleton, and the top ring is movably embedded in the interior of the filter bag body.

[0009] Preferably, the bottom end of the skeleton is fixedly connected to a bottom ring, and the middle of the bottom ring is fixedly connected to a cross.

[0010] Preferably, the bottom ring and the cross are both movably embedded in the base fabric.

[0011] Preferably, the top and bottom ends of the movable strip are both fixedly connected to the conductive fiber layer, and the movable strip is movably connected to the filter bag body through the conductive fiber layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This antistatic polyester blended conductive fiber dust filter bag, through the outer groove, inner groove, connecting rod and arc strip, makes it possible for the dust filter bag to be docked with the flower plate hole on the dust collector. By observing whether the arc strip remains embedded in the inner groove of the spring coil, the connection between the outer groove of the spring coil and the flower plate hole can be adjusted in time, reducing the probability of improper installation such as the spring coil being too loose or too tight, thereby reducing the adverse effects on the filtering effect of the filter bag.

[0014] 2. This antistatic polyester blended conductive fiber dust filter bag, through the conductive fiber layer and movable strips, allows the static electricity generated on the surface of the dust filter bag to be conducted to the bottom of the filter bag through the conductive fibers, reducing the area of dust adsorbed by static electricity on the filter bag surface. At the same time, when the airflow passes through the filter bag, it can drive the movable strips on the outer surface of the filter bag to float, so that the dust adsorbed on the surface of the filter bag can be shaken off by the floating of the movable strips, reducing the probability of dust adsorbed on the surface of the filter bag, thereby reducing the difficulty of cleaning the dust on the surface of the filter bag.

[0023] like Figures 1 to 4 As shown, the antistatic polyester mixed conductive fiber dust removal filter bag of this embodiment includes a filter bag body 6, the top of the filter bag body 6 is fixedly connected to a ring 1, the outer wall of the ring 1 is provided with an outer groove 3, the inner wall of the ring 1 is movably connected to a spring ring 2, the inner wall of the spring ring 2 is provided with an inner groove 5, the interior of the inner groove 5 is provided with four arc bars 4, the interior of the filter bag body 6 is embedded with a skeleton 10, the outer wall of the filter bag body 6 is fixedly connected to a conductive fiber layer 8, the outside of the conductive fiber layer 8 is provided with a movable bar 7, the bottom end of the filter bag body 6 is fixedly connected to a base cloth 9, and the inner wall of the filter bag body 6 is fixedly connected to a polyester layer 11.

[0024] Specifically, the diameter of the collar 1 is larger than the diameter of the filter bag body 6, so that the top of the filter bag can be smoothly stuck on the circular hole corresponding to the flower plate, which is beneficial to increase the stability of the filter bag after it is engaged with the flower plate hole through the sleeve spring ring 2. The inner diameter of the outer groove 3 is adapted to the diameter of the flower plate hole, so that the filter bag body 6 can be stuck on the flower plate through the outer groove 3 on the collar 1, which is convenient for the installation of the filter bag. The sleeve spring ring 2 can be deformed to make the bottom end of the collar 1 at the top of the filter bag body 6 pass through the flower plate hole smoothly, so that the outer groove 3 on the collar 1 can smoothly engage with the flower plate. The hole is fitted, and the function of the inner groove 5 is to accommodate the arc strip 4 and protect the arc strip 4. There are four arc strips 4, and the radius of the four arc strips 4 is the same as the radius of the inner groove 5, so that the arc strip 4 can be embedded in the inner groove 5. At the same time, the two ends of the four arc strips 4 are not connected to each other, so that the four arc strips 4 protrude from the inner groove 5 when the spring ring 2 is not in a normal state, thereby facilitating the operator to find and adjust the spring ring 2 that is not installed in place, so that the filter bag body 6 can be installed in place, reducing the damage to the filter bag. The adverse effects caused by normal use, the skeleton 10 is a carbon fiber structure with good flexibility, which can keep the filter bag in an open state, thereby increasing the stability of the filter bag when passing through the airflow, the conductive fiber is a chemical fiber or metal fiber spun after mixing a conductive medium into a polymer, which has a high performance in eliminating and preventing static electricity, making it difficult for the surface of the filter bag body 6 to generate static electricity, thereby reducing the probability of dust being adsorbed on the surface of the filter bag body 6 due to static electricity, and reducing the difficulty of cleaning the dust on the surface of the filter bag, the movable bar 7 is made of high-temperature resistant chemical fiber material, and its length is the same as that of the filter bag body 6, so that the movable bar 7 can remain relaxed, and when the airflow passes through the filter bag, it can drive the movable bar 7 to float on the outer surface of the filter bag, thereby helping to shake off the dust adsorbed on the outer surface of the filter bag, so that the dust falls into the ash hopper of the dust collector, reducing the dust adsorbed on the outer surface of the filter bag, the function of the bottom cloth 9 is to seal the bottom of the filter bag body 6, so that the airflow can smoothly enter the cavity channel formed inside the filter bag after passing through the filter bag, thereby achieving filtration of dust in the airflow.

[0025] Furthermore, a connecting rod 12 is movable through the middle of the arc bar 4, and both ends of the connecting rod 12 are fixedly connected to the top and bottom of the inner groove 5 respectively. The function of the connecting rod 12 is to enable both ends of the arc bar 4 to move in the inner groove 5, thereby realizing the protrusion of the arc bar 4 from the inside of the inner groove 5.

[0026] Furthermore, the arc bar 4 is movably connected to the inner groove 5 through the connecting rod 12. When the spring ring 2 is not installed in place with the flower plate hole, the arc bar 4 will protrude from the inner groove 5 on the inner wall of the spring ring 2, thereby facilitating the operator to promptly discover and install the spring ring 2 in place.

[0027] Furthermore, a top ring 13 is fixedly connected to the top of the skeleton 10, and the top ring 13 is movably embedded in the interior of the filter bag body 6. The outer diameter of the top ring 13 is the same as the outer diameter of the bottom ring 14, so that the skeleton 10 can reinforce and support the bag body of the filter bag body 6, thereby facilitating the floating of the movable bar 7 outside the filter bag.

[0028] Furthermore, the bottom end of the skeleton 10 is fixedly connected to a bottom ring 14, and the middle of the bottom ring 14 is fixedly connected to a cross 15. The bottom ring 14 and the cross 15 can increase the support of the bottom end of the skeleton 10 to the filter bag body 6, thereby increasing the stability of the filter bag body 6 during cleaning.

[0029] Furthermore, the bottom ring 14 and the cross 15 are movably embedded in the base cloth 9. The bottom ring 14 and the cross 15 can stretch the base cloth 9 so that the base cloth 9 can remain taut, thereby facilitating the contact between the airflow and the base cloth 9 and blowing off the dust adsorbed by the base cloth 9.

[0030] Furthermore, the top and bottom ends of the movable bar 7 are fixedly connected to the conductive fiber layer 8, and the movable bar 7 is movably connected to the filter bag body 6 through the conductive fiber layer 8. The movable bar 7 can be blown while the airflow passes through the filter bag body 6 and shake on the outer wall of the filter bag body 6, thereby reducing the probability of dust being adsorbed on the outer surface of the filter bag body 6.

[0031] The method of using this embodiment is as follows: when installing the antistatic polyester mixed conductive fiber dust filter bag, the filter bag body 6 can be passed through the flower plate hole on the dust collector first, and then the spring ring 2 can be squeezed inward to deform the spring ring 2. At this time, the arc strip 4 on the inner groove 5 of the inner wall of the spring ring 2 will protrude from the inner groove 5 through the connecting rod 12, and then the outer groove 3 of the spring ring 2 is docked with the flower plate hole so that the ring 1 is stuck on the flower plate hole, and then the spring ring 2 is loosened to restore the spring ring 2. Then the arc strip 4 on the inner groove 5 of the inner wall of the spring ring 2 can be observed. If the arc strip 4 protrudes from the inner groove The inner wall of the groove 5 needs to adjust the position of the sleeve spring ring 2 until the arc strip 4 is embedded in the inner groove 5 and does not protrude from the inner groove 5, which indicates that the sleeve spring ring 2 has been installed in place, and when the air flow passes through the outer surface of the filter bag body 6 and enters the interior of the filter bag body 6, the movable strip 7 located on the outer surface of the filter bag body 6 will be blown and shaken on the outer surface of the filter bag body 6, so that the dust adsorbed on the outer surface of the filter bag body 6 can be shaken off under the shaking of the movable strip 7, so that the dust accumulated on the outer surface of the filter bag body 6 falls into the ash hopper of the dust collector, so that the dust adsorbed on the surface of the filter bag body 6 is reduced.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
