Description

Technical Field

[0001] This utility model relates to the field of boiler soot blowers, specifically a boiler soot blower with a support roller. Background Technology

[0002] Boiler soot blowers adopt a new generation of ash removal technology and are a replacement for acoustic / infrasonic / steam soot blowers. They are used to remove ash from boiler heat exchange surfaces, dust collectors, etc. Among them, the long telescopic soot blower is a type of boiler soot blower.

[0003] The existing telescopic sootblower blows gas into the boiler by moving and rotating the sootblowing pipe to perform soot blowing. During the movement and rotation of the sootblowing pipe, it is supported by rollers to ensure its stability and avoid excessive friction at the connection with the boiler. However, the existing rollers are all fixed. During use, the rollers will wear down after friction with the sootblowing pipe, resulting in failure to make contact with the sootblowing pipe and achieve the lifting effect. Therefore, this application designs a boiler sootblower that adaptively lifts the pipe to ensure the lifting effect and solves this defect of the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a boiler soot blower with support rollers, which has advantages such as adaptive lifting to ensure lifting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boiler soot blower with a support roller, comprising a beam box, a rack, a moving gearbox, a lifting valve, an inner tube, an outer tube, a reduction motor, a transmission gear, a chain, and a nozzle;

[0006] The beam box is provided with a pair of racks, and a movable gearbox that moves linearly to the upper limit of the beam box is meshed on the racks. A lifting valve is installed on the outside of the beam box. The exhaust port of the lifting valve is connected to the inner tube. An outer tube that rotates with the movable gearbox is sleeved on the inner tube. The other end of the outer tube is connected to the nozzle.

[0007] The beam box is equipped with a roller support box located outside the outer tube, and the roller support box is provided with a pair of rollers that are arranged opposite to each other and are in contact with the outside of the outer tube;

[0008] An adjustment structure is provided between the support roller and the support roller box to adaptively fit the outer tube and support the outer tube;

[0009] A locking component for locking after adaptive adjustment is also provided between the roller and the roller box;

[0010] The beam box is equipped with a cleaning component for cleaning particles adhering to the outside of the outer tube.

[0011] As a preferred embodiment of this utility model, the adjustment structure includes a support rod installed on the top and bottom walls of the inner cavity of the roller box. An outer sleeve is slidably sleeved on the outside of the support rod. A stainless steel spring connected to the support rod is installed inside the outer sleeve. A roller seat for rotating the roller is installed at the other end of the outer sleeve.

[0012] By adopting the above technical solution, it is easy for the support roller to move adaptively and fit against the surface of the support roller after the surface of the support roller is worn.

[0013] In a preferred embodiment of this invention, the support rod and the outer sleeve will not separate, and the stainless steel spring is in a compressed state when the roller seat contacts the outer tube.

[0014] By adopting the above technical solution, the support rollers are guaranteed to have a reserved distance for adaptive movement.

[0015] As a preferred technical solution of this utility model, the locking assembly includes locking tooth blocks installed on the front and rear side walls of the inner cavity of the roller box and a hollow cylinder installed on the front and rear side walls of the roller seat.

[0016] The locking tooth block has several equally spaced tooth grooves, and a return spring is installed inside the hollow cylinder. The other end of the return spring is equipped with a movable tooth block that meshes with the tooth grooves.

[0017] By adopting the above technical solution, the rollers are locked and fixed after adaptive movement and adjustment.

[0018] As a preferred technical solution of this utility model, the tooth groove is a right trapezoid shape, and the opposite faces of the upper and lower movable tooth blocks located at one end of the tooth groove are inclined, with an inclination angle of thirty degrees.

[0019] By adopting the above technical solution, it is ensured that the moving tooth block can move within the tooth groove and avoids retraction.

[0020] As a preferred embodiment of the present invention, the cleaning assembly includes a cleaning ring installed inside the roller housing and located outside the outer tube, and a cleaning brush that contacts the outside of the outer tube is installed inside the cleaning ring.

[0021] The above technical solution facilitates the cleaning of external particles adhering to the outer tube and avoids contact with the support rollers, thus reducing lifting wear.

[0022] In a preferred embodiment of this invention, when the return spring is in a compressed state, the moving tooth block separates from the tooth groove.

[0023] By adopting the above technical solution, the moving tooth block can be adjusted and locked within the tooth groove.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This boiler soot blower with rollers supports the outer tube, allowing it to rotate and move. As the rollers wear down, an adjustment structure allows them to adaptively adjust to fit the outer tube. A locking component locks the adjusted tube in place, and a cleaning component removes particulate matter from the outer tube's surface to prevent accelerated wear and ensure effective support.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 2 The boiler soot blower with rollers in this embodiment includes a beam box 1, a rack 2, a moving gearbox 3, a lifting valve 4, an inner tube 6, an outer tube 7, a reduction motor 8, a transmission gear 9, a chain 10, and a nozzle 11.

[0034] A pair of symmetrically distributed racks 2 are installed and fixed on the front and rear side walls of the inner cavity of the beam box 1. A movable gearbox 3 that moves linearly to the upper limit of the beam box 1 is meshed on the racks 2. A drive motor is installed in the movable gearbox 3 to drive the meshing gear to mesh with the racks 2. A lifting valve 4 is installed and fixed on the outer side of the beam box 1. The exhaust port of the lifting valve 4 is connected to the inner tube 6. An outer tube 7 that rotates circumferentially with the movable gearbox 3 is slidably sleeved on the outside of the inner tube 6. The other end of the outer tube 7 is connected to the nozzle 11.

[0035] The mouthpiece 11 has multiple air holes.

[0036] In this embodiment, a roller box 12 located outside the outer tube 7 is installed and fixed on the inner wall of the beam box 1. The roller box 12 is provided with a pair of rollers 17 that are arranged opposite to each other and fit against the outside of the outer tube 7.

[0037] Please see Figures 3 to 5 An adjustment structure is provided between the support roller 17 and the support roller box 12 to adaptively fit the outer tube 7 and support the outer tube 7.

[0038] It should be noted that the adjustment structure includes a support rod 13 installed and fixed to the top and bottom walls of the inner cavity of the roller box 12. An outer sleeve 14 is slidably sleeved on the outside of the support rod 13. A stainless steel spring 15 connected to the support rod 13 is installed and fixed inside the outer sleeve 14. A roller seat 16 that rotates the roller 17 internally is installed and fixed at the other end of the outer sleeve 14.

[0039] The support rod 13 and the outer sleeve 14 will not separate to avoid the inability to reset after separation. When the roller seat 16 contacts the outer tube 7, the stainless steel spring 15 is in a compressed state to ensure that the roller seat 16 has space for adaptive movement and adjustment.

[0040] In this embodiment, a locking component is also provided between the roller 17 and the roller box 12 for locking after adaptive adjustment.

[0041] It should be noted that the locking assembly includes locking teeth 18 that are installed and fixed to the front and rear side walls of the inner cavity of the roller box 12 and hollow cylinders 20 that are installed and fixed to the front and rear side walls of the roller seat 16.

[0042] The locking tooth block 18 has several equally spaced tooth grooves 19, and a return spring 21 is installed and fixed inside the hollow cylinder 20. The other end of the return spring 21 is installed and fixed with a movable tooth block 22 that meshes with the tooth grooves 19.

[0043] The tooth groove 19 is a right trapezoidal shape. The opposite faces of the upper and lower movable tooth blocks 22 located at one end of the tooth groove 19 are inclined at an angle of 30 degrees, ensuring that the movable tooth blocks 22 can move within the tooth groove 19 without moving back after moving.

[0044] In this embodiment, the beam box 1 is equipped with a cleaning component for cleaning the external particles adhering to the outer tube 7.

[0045] It should be noted that the cleaning assembly includes a cleaning ring 23 installed and fixed inside the roller box 12 and located outside the outer tube 7, and a cleaning brush 5 that contacts the outside of the outer tube 7 is installed and fixed inside the cleaning ring 23.

[0046] The cleaning ring 23 is located on the left side inside the roller box 12.

[0047] When the return spring 21 is in a compressed state, the moving tooth block 22 separates from the tooth groove 19.

[0048] The working principle of the above embodiments is as follows:

[0049] During use, while the air intake is controlled by the lifting valve 4, the moving gearbox 3 drives the whole to move on the meshing rack 2, so that the outer tube 7 moves synchronously outside the inner tube 6. At the same time, the geared motor 8 drives the transmission gear 9 to rotate, and the meshing of the transmission gear 9 with the chain 10 drives the outer tube 7 to rotate while moving.

[0050] During the rotation and movement of the outer tube 7, a pair of support rollers 17 rotate synchronously within the support roller seat 16 to support the outer tube 7. At the same time, during the rotation and movement of the outer tube 7, the cleaning brush 5 located in the cleaning ring 23 contacts the surface of the outer tube 7 to clean the particles on the surface of the outer tube 7, thus preventing the particles from contacting the support rollers 17 and accelerating the wear of the support rollers 17.

[0051] In addition, as the support roller 17 wears out and separates from the outer tube 7, the elastic extension and resetting action of the stainless steel spring 15 pushes the outer sleeve 14 to move outside the support rod 13, and simultaneously drives the support roller seat 16 to move, so that the support roller 17 adapts to wear and adjusts to ensure that it always keeps in contact with the outside of the outer tube 7 for support.

[0052] During the adaptive movement adjustment of the support roller 17, the support roller seat 16 moves synchronously, and the hollow cylinder 20 moves synchronously. With the extension and contraction of the return spring 21, the moving tooth block 22 moves within the tooth groove 19 on the locking tooth block 18. With the right-angled trapezoidal setting of the tooth groove 19, it is ensured that after the support roller 17 contacts the outer tube 7, the locking tooth block 18 moves synchronously and inserts into the tooth groove 19 and cannot return to its original position. This achieves locking and fixing after the support roller 17 adaptively adjusts and lifts, ensuring the lifting effect.

[0053] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
