Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a regulating valve component used for a chamber bag type dust collector. Background Art

[0002] The bag filter filters the dusty gas by utilizing the filtering effect of the filter bag fiber fabric, and is suitable for capturing fine, dry, non-fibrous dust. When the dusty gas enters the bag filter, the dust with large particles and high specific gravity settles down due to the effect of gravity and falls 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. As the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference on both sides of the filter material is large, some fine dust particles attached to the filter material will be squeezed over, reducing the efficiency of the dust collector. In addition, if the resistance of the dust collector is too high, the air volume of the dust removal system will drop significantly. Therefore, after the resistance of the dust collector reaches a certain value, it is necessary to clean the dust in time.

[0003] When the bag dust collector is cleaned offline, it is necessary to shut off the incoming airflow in the dust collection chamber to be cleaned before cleaning, and then clean the filter bags through the reverse suction pipe or pulse valve; and because industrial dust removal is a continuous operation, the dust collector will frequently switch between the dust removal and cleaning processes, especially at the flue gas inlet of the dust collector. The opening and closing frequency of traditional valves is too high, and the valve plate and actuator of the valve are often under the impact of flue gas, which can easily lead to a reduction in the sealing performance of the valve, causing the new flue gas to run around in the dust collection chamber during cleaning, greatly reducing the cleaning efficiency. Utility Model Content

[0004] The utility model aims to provide a regulating valve member for a chamber bag type dust collector to solve the above problems.

[0005] The utility model is realized by the following technical solutions:

[0006] A regulating valve member for a chamber bag filter comprises a cylinder and a valve plate, wherein a push rod is arranged at the output end of the cylinder, and a valve plate for blocking air holes is spherically connected to the end of the push rod;

[0007] A connecting rod is arranged on the side wall facing away from the valve plate, a matching clamping ring is arranged on the inner circumferential wall of the air hole, a grille is arranged on the inner circumferential wall of the clamping ring, and a sleeve is arranged in the middle of the grille for the connecting rod to movably penetrate;

[0008] A plurality of guide grooves are opened on the outer circumferential wall along the axial direction of the connecting rod, and a sliding groove corresponding to the guide groove is arranged on the inner circumferential wall of the sleeve, and a channel for the ball to rotate is formed between each sliding groove and the corresponding guide groove.

[0009] In view of the problem that the inlet and outlet air ducts in the existing dust collector are frequently opened and closed, resulting in the corresponding valves not being properly sealed, especially during the cleaning process, when the dust removal process is paused, new flue gas will still enter the dust removal chamber, greatly hindering the cleaning progress; in this regard, the inventors have optimized the design of the existing valve structure to ensure that the valve plate and the air hole fit tightly when the air hole is frequently opened and closed, so as to ensure the normal cleaning process of the dust collector.

[0010] The specific working principle is as follows:

[0011] The output end of the cylinder drives the push rod to perform linear reciprocating motion to drive the valve plate to block or unblock the air hole; and because the valve plate will be affected by the flow of smoke when it moves, and then the valve plate will produce a certain degree of shaking due to the uneven distribution of the impact force of the smoke on its surface, the technical solution is provided with a connecting rod on the side wall of the valve plate, and a matching clamping ring is provided in the air hole. The clamping ring has a grille, and a sleeve for the connecting rod to move through is provided in the middle of the grille, that is, the swing amplitude of the valve plate is reduced by the limiting cooperation of the connecting rod and the sleeve on the moving path of the valve plate, ensuring that the air hole is always within the coverage area of ​​the valve plate, and at the same time, the push rod and the valve plate are connected by a ball joint. Even if the valve plate has a certain degree of swing during the movement, the power of the cylinder output end driving the push rod to act on the valve plate can ensure the normal movement of the valve plate, and no tensile deformation or torsional deformation will occur between the push rod and the valve plate; that is, through the cooperation of the connecting rod and the sleeve, and the ball joint cooperation of the push rod and the valve plate, it is possible to ensure that the valve plate moves smoothly and the valve plate blocks the air hole tightly.

[0012] It should be noted that the valve plate will be affected by the airflow when it moves, and the axial length of the sleeve is smaller than the axial length of the connecting rod. If the connecting rod is limited by the sleeve alone, a certain degree of wear will occur between the outer wall of the connecting rod and the inner wall of the sleeve. In this regard, the inventor optimizes and upgrades the sleeve and the connecting rod, that is, by setting a plurality of guide grooves on the outer wall of the connecting rod and setting corresponding slide grooves on the inner wall of the sleeve, and using balls to replace the sliding friction generated when the sleeve and the connecting rod move relative to each other with rolling friction, thereby reducing the degree of wear between the sleeve and the connecting rod; further, positioning grooves adapted to the balls are arranged at intervals at the bottom of the slide grooves, and the cross-section of the guide grooves is in an arc shape adapted to the balls. A single ball is confined between the positioning groove and the guide groove and will not move linearly with the connecting rod, wherein the length of the guide groove is smaller than the length of the connecting rod, and can meet the normal movement of the connecting rod and the valve plate, that is, when the balls are in contact with the two extreme positions of the guide groove respectively, the valve plate can smoothly realize the opening and closing control of the air hole in the dust removal process requirements.

[0013] A limiting cylinder is provided in the middle of the upper surface of the valve plate, a ball head is provided at the end of the push rod, a support is provided at the bottom of the limiting cylinder, and the ball head is accommodated in the support. Furthermore, a ball head is provided at the end of the push rod, and a support matching the ball head is provided on the side wall of the valve plate, and the ball head is wrapped by the limiting cylinder after matching with the support, so as to ensure that there is a certain range of motion between the push rod and the valve plate, and at the same time ensure the effective linkage between the valve plate and the push rod.

[0014] The inner diameter of the upper section of the limiting cylinder is smaller than the inner diameter of the lower section, and the inner diameter of the upper section of the limiting cylinder is larger than the outer diameter of the push rod, and the diameter of the ball head is larger than the inner diameter of the upper section of the limiting cylinder. Preferably, the technical scheme is a further optimized design of the valve plate and the push rod, specifically, by converting the fixed connection between the push rod and the valve plate into a movable connection between the ball head and the support, and then using the limiting cylinder to limit and prevent the ball head from falling off, the inner diameter of the upper section of the limiting cylinder is smaller than the inner diameter of the lower section, and the inner diameter of the upper section of the limiting cylinder is larger than the outer diameter of the push rod, which can ensure that the push rod can smoothly enter the limiting cylinder, and at the same time, the gap between the upper section of the limiting cylinder and the outer wall of the push rod can provide a certain degree of activity space for the push rod, and the diameter of the ball head is larger than the inner diameter of the limiting cylinder, which can prevent the ball head from detaching from the limiting cylinder, and realize a smooth transition between the inner wall of the upper section of the limiting cylinder and the inner wall of the lower section, so as to reduce the degree of wear between the ball head and the inner wall of the limiting cylinder.

[0015] The axial length of the connecting rod is greater than the maximum displacement of the push rod. Preferably, the axial length of the connecting rod is greater than the maximum displacement of the push rod, that is, when the push rod is extended or retracted, the connecting rod always maintains contact with the sleeve to ensure stable movement of the valve plate.

[0016] The cylinder is fixed by a mounting seat, and a through hole is opened at the bottom of the mounting seat for the cylinder output end to pass through, and a plurality of guide holes are also opened at the bottom of the mounting seat along the circumference of the through hole. A positioning cylinder is sleeved on the outer circumferential wall of the cylinder output end, and the lower end of the positioning cylinder is fixed on the mounting seat and completely covers the through hole; an annular limiting plate is fixed on the outer circumferential wall of the cylinder output end, and a plurality of guide rods whose axes are parallel to the axis of the positioning cylinder are provided on the limiting plate, and the guide rods are aligned with the guide holes. Furthermore, during the dust removal period, an offline cleaning process will be carried out at irregular intervals. After the cleaning process is completed, as the valve plate is reopened, in order to ensure that the valve plate maintains its stability during the switching process of opening and closing, the technical solution fixes the cylinder to the dust collector body through a mounting seat. When the valve plate is opened, the closed valve plate is easily impacted by the airflow in the flue gas inlet pipe, and an annular limit plate is provided on the outer circumferential wall of the output end of the cylinder, and a plurality of guide rods aligned with the guide holes are provided on the limit plate. At this time, the lower end portion of the guide rod is completely inserted into the guide hole. The guide hole limits the guide rod and the positioning cylinder limits the push rod, so that the stability of the push rod can be continuously guaranteed, thereby ensuring the airtightness of the air hole corresponding to the dust removal process during cleaning.

[0017] A follower cylinder concentric with the connecting rod is provided on the side wall of the limit plate facing the positioning cylinder; when the valve plate blocks the air hole, the limit plate contacts the end face of the positioning cylinder, the follower cylinder is placed in the positioning cylinder, and the outer circumferential wall of the follower cylinder fits the inner circumferential wall of the positioning cylinder. Preferably, a follower cylinder is provided on the limit plate, and when the guide rod is inserted into the guide hole, the follower cylinder moves into the gap between the positioning cylinder and the push rod until the limit plate contacts the end of the positioning cylinder, and the push rod cannot move further, thereby preventing the push rod from excessive displacement; wherein, the follower cylinder is parallel to the axes of the multiple guide rods inserted into the guide holes, which can further improve the stability of the main body of the push rod during movement.

[0018] Two sealing ring plates are sleeved on the outer wall of the connecting rod and are respectively connected to the end faces of both ends of the sleeve, and ear plates for sealing the guide groove are provided on the sealing ring plates. Preferably, when the connecting rod moves with the valve plate, such as when the air hole is opened, the movement of the airflow continues, and there is a gap between the sleeve and the connecting rod. The airflow is easy to run around in the gap, thereby generating noises of varying degrees. For this reason, the inventors respectively set sealing ring plates at both ends of the sleeve, and set ear plates matching the guide groove on the inner circumferential wall of each sealing ring plate. The setting of the sealing ring plates and the ear plates can reduce the probability of the airflow entering the gap to a certain extent, while ensuring the normal movement of the connecting rod.

[0019] The ear plate is a flexible rubber plate, and the transverse cross section of the guide groove is a semicircular shape matching the ear plate. Preferably, the ear plate is a flexible rubber plate, and is semicircular, so as to achieve flexible contact with the inner wall of the guide groove.

[0020] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0021] 1. In the utility model, the swing amplitude of the valve plate is reduced by the limit cooperation of the connecting rod and the sleeve on the moving path of the valve plate, ensuring that the air hole is always within the coverage area of ​​the valve plate. At the same time, the push rod and the valve plate are connected by a ball joint. Even if the valve plate swings to a certain extent during the movement, the power of the cylinder output end driving the push rod to act on the valve plate can ensure the normal movement of the valve plate, and no tensile deformation or torsional deformation will occur between the push rod and the valve plate; that is, through the cooperation of the connecting rod and the sleeve, and the ball joint cooperation of the push rod and the valve plate, the valve plate can be ensured to move smoothly and the valve plate can be tightly sealed to the air hole;

[0022] 2. In the utility model, the ball joint of the push rod and the valve plate makes the valve plate movable in the radial direction relative to the push rod. When the valve plate blocks the air hole, the position error during welding or installation can be effectively eliminated, thereby improving the sealing effect of the valve plate.
