Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bag dust removal, and more specifically, to a bag dust collector. Background Art
[0002] A bag dust collector is a dust removal device that uses filter bags to filter dust-laden gas and separate dust from the gas. Bag dust collectors are usually large in size and require sufficient installation space, so bag dust collectors are generally installed outdoors.
[0003] A top cover is provided on the top surface of the bag collector. People open the top cover to facilitate the inspection, replacement and maintenance of the filter bags. The top surface of the existing bag collector is provided with a number of bolts, which are arranged vertically. A pressure block is slidably connected to the bolt, and a nut located above the pressure block is threadedly connected to the bolt. People tighten the nuts so that the two ends of the pressure block press the top cover, thereby ensuring the sealing between the top cover and the bag collector. However, because the bag collector is installed outdoors, when it rains, rainwater can easily hit between the bolts and nuts. Over time, the bolts and nuts will quickly rust, which in turn affects the unscrewing of the nuts.
[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0018] Bag dust collector, such as Figure 1 and Figure 2As shown, it includes a dust collector body 1, the top surface of the dust collector body 1 is provided with several top covers 2, the top covers 2 are provided with several vertically arranged bolts 3, the bolts 3 are slidably connected with a pressure block 4, the bolts 3 are threadedly connected with a nut 5 located above the pressure block 4, the top surface of the dust collector body 1 is fixedly connected with a support column 6 located between two adjacent top covers 2, the top end of the support column 6 is rotatably connected with a baffle 7 for blocking above the bolt 3, and the top cover 2 is fixedly connected with a pull handle 8. When the baffle 7 conflicts with the top end of the pull handle 8, the baffle 7 and the support column 6 are clamped. The angle is 90 degrees. In normal state, the lower side of the baffle 7 is resisted by the pull handle 8, making it difficult for the baffle 7 to continue to rotate downward and maintain a 90-degree angle with the support column 6, so that the baffle 7 maintains a horizontal state and is relatively stable. The baffle 7 can shield the bolt 3 from falling rainwater, so that the rainwater is not easy to wet the bolt 3, so that the bolt 3 and the nut 5 are not easy to rust. The baffle 7 can also block the sunlight for the bolt 3 and the nut 5, thereby reducing the impact of exposure to the sun on the bolt 3 and the nut 5, ensuring the overall life of the bolt 3 and the nut 5, and the baffle 7 The force required for rotation is greater than the gravity of the baffle 7. This arrangement ensures that no matter what state the baffle 7 is rotated to, the baffle 7 will not rotate relatively. When people need to open the top cover 2, they rotate the baffle 7 back to the top plate to be opened, so that there is still a large space around the nut 5 for people to move, and the baffle 7 will not affect people from opening the top cover 2. A rotation groove is provided at one end of the baffle 7, and a rotation rod is provided in the rotation groove. The two ends of the rotation rod are respectively fixed on the two inner walls opposite to each other connected to the rotation groove. One end of the support rod is provided with a rotation slot. The rod passes through the through hole, and the baffle 7 rotates with the rotating rod as the rotating axis, and the inner wall of the through hole is provided with a friction pattern, which is used to increase the friction between the rotating rod and the inner wall of the through hole, so that the force required for the rotation of the baffle 7 is greater than the gravity of the baffle 7. The baffle 7 is made of PP plastic, which has the characteristics of light weight, high strength and long life, so that the baffle 7 as a whole has high strength and life. The top surface of the baffle 7 is coated with a sunscreen coating, which improves the sun protection ability of the baffle 7 and ensures that sunlight is not easy to penetrate the baffle 7.
[0019] like Figure 2 and Figure 3As shown, a spacer block 9 is provided between the bolt 3 and the dust collector body 1. The setting of the spacer block 9 makes the position of the bolt 3 on the top surface of the dust collector body 1 relatively high, so that the water on the top surface of the dust collector body 1 is not easy to be contacted by the bolt 3. The top surface of the dust collector body 1 is fixedly connected to a plurality of rotating seats 10, one end of the top cover 2 is rotatably connected to the rotating seat 10, and the pull handle 8 is close to the end of the top cover 2 facing away from the rotating seat 10, wherein the end of the top cover 2 connected to the rotating seat 10 is the fixed end, and the end of the top cover 2 facing away from the rotating seat 10 is the movable end. Two rows of cover groups are formed on the top surface of the dust collector body 1, and several bolts 3 are located between the two rows of cover groups. The top covers 2 in the two rows of cover groups are arranged in a one-to-one correspondence, and the movable ends of the two corresponding top covers 2 are arranged close to each other and the pull handles 8 on the two corresponding top covers 2 are used to support the same baffle 7. This arrangement enables a pressing block 4 to press the movable ends of the two top covers 2, which can reduce the number of bolts 3 settings. When people need to open all the top covers 2 at one time, the number of lock nuts to be unscrewed can be reduced, which is convenient for people to open and close the top covers 2 and support The number of pull handles 8 of the baffle 7 is increased, which ensures the support capacity of the pull handle 8 for the baffle 7. At the same time, the pull handle 8 also provides a fulcrum for people to flip over the top cover 2, making it easier for people to open the top cover 2. The cross section of the baffle 7 is arranged in a herringbone shape, and rainwater can flow along the top surface of the baffle 7 toward the two rows of cover groups. A plane 11 and an inclined surface 12 are provided on the top cover 2. The pull handle 8 is located between the plane 11 and the inclined surface 12. The closer the distance between the inclined surface 12 and the top surface of the dust collector body 1 is to the pull handle 8, the larger it is. The plane 11 is used to contact the two ends of the pressing block 4, increasing The contact area between one end of the pressure block 4 and the plane 11 is increased, thereby ensuring the squeezing effect of the pressure block 4. Part of the projection of the baffle 7 on the top cover 2 falls on the inclined surface 12, and the inclined surface 12 is inclined toward the fixed end of the top cover 2, so that the rainwater on the baffle 7 will fall directly on the inclined surface 12 when it falls. At this time, the rainwater will flow along the inclined surface 12 to one side of the dust collector body 1, so that the rainwater flows down from the top surface of the dust collector body 1, which can guide the rainwater in the direction away from the bolt 3, further reducing the possibility of rainwater contacting the bolt 3.
