Description

Technical Field

[0001] The utility model relates to the technical field of soot blowers, in particular to a fixing device for a soot blower. Background Technique

[0002] A soot blower is a device that uses media such as steam, air, or ultrasonic waves to clean the dust on the surface of furnace tubes. It is mainly used to clean the dust and ash and other impurities on the inner walls of equipment such as boilers and coal-fired engines to ensure the normal operation of the equipment. It is usually composed of components such as a soot blowing pipe and an operation valve.

[0003] The utility model patent with the authorization announcement number of CN 217653873 U discloses "a fixing device for a soot blower". By placing the soot blower body on one side of the mounting seat, and the outer wall on one side of the soot blower body is in contact with the first rubber pad in the mounting seat, then moving the positioning seat towards the mounting seat until the first rubber pad in the positioning seat is in contact with the outer wall on the other side of the soot blower body, and the insertion rod is inserted into the insertion hole. At this time, screwing the positioning screw into the positioning hole achieves the positioning effect on the positioning seat. Thus, with the cooperation of the positioning groove, the fixed installation effect of the soot blower body is realized, and the soot blower body is protected. After the positioning screw is screwed into the positioning hole, the lead screw is driven to rotate through the action of the turntable. The lead screw drives the threaded block to move downward. The threaded block drives the fixed rod to move downward with the cooperation of the movable groove and the guide rod. The fixed rod drives the pressing plate to move downward until the second rubber pad at the bottom of the pressing plate is in contact with the top outer wall of the soot blower body. Thus, with the cooperation of the mounting seat, the positioning seat, the positioning groove and the first rubber pad, the stability of the soot blower body during operation is ensured. However, there are still the following deficiencies in the above-mentioned prior art solution: First, during the installation and disassembly of the positioning seat, specific tools are required to disassemble and assemble the positioning screw. Using inappropriate tools may cause the positioning screw to slip; if the operator applies too much torque during assembly exceeding the load limit of the positioning screw, it may cause damage to the positioning screw; if the torque is too small, insufficient fastening force cannot be provided. All of the above situations may cause the occurrence of thread slipping, affecting the installation and disassembly of the positioning seat. Second, under the action of the first rubber pad, a closed space is formed between the mounting seat and the positioning seat. When the soot blower is working, the closed space is prone to heat accumulation, affecting the service life and working efficiency of the motor in the soot blower. Therefore, a fixing device for a soot blower is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for a soot blower to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present utility model provides the following technical solutions: A soot blower fixing device, comprising a main body mechanism and a soot blower body. The main body mechanism includes a lower cover and an upper cover. A disassembly and assembly mechanism is provided on the main body mechanism, and a heat dissipation mechanism is provided on the main body mechanism;

[0006] The disassembly and assembly mechanism includes an installation groove. A clamping block is slidably connected inside the installation groove. A guide rod is fixedly connected inside the installation groove. One side of the clamping block is fixedly connected with a return spring. The return spring is sleeved outside the guide rod. A round roller is fixedly connected inside the installation groove. One side of the clamping block is fixedly connected with a pulling rope. The bottom of the pulling rope is fixedly connected with a handle. The top of the lower cover is fixedly connected with a positioning rod;

[0007] The heat dissipation mechanism includes a first heat dissipation hole. A first dust-proof net is fixedly connected inside the first heat dissipation hole. A second heat dissipation hole is opened on the upper cover. A second dust-proof net is fixedly connected inside the second heat dissipation hole.

[0008] Preferably, both the left and right sides of the bottom of the lower cover are fixedly connected with two support legs that are symmetrically distributed front and back. The upper cover is located on top of the lower cover, and the soot blower body is located between the lower cover and the upper cover.

[0009] Preferably, the installation groove is opened on the lower cover. The number of installation grooves is two and they are symmetrically distributed front and back. The top of the clamping block extends to the top of the lower cover.

[0010] Preferably, a limiting block is fixedly connected to the bottom of the clamping block. A limiting groove adapted to the movement track of the limiting block is opened inside the lower cover. The limiting groove communicates with the installation groove. A clamping groove is opened on the bottom of the upper cover. The size of the clamping groove is adapted to the movement track of the clamping block.

[0011] By installing a limiting block at the bottom of the clamping block and opening a limiting groove inside the lower cover, the moving direction and moving distance of the clamping block are restricted. The opening of the clamping groove provides space for the movement of the clamping block.

[0012] Preferably, the number of round rollers in a single installation groove is two. The surface of the round roller is designed to be smooth. The pulling rope is in contact with the surface of the round roller.

[0013] Since the surface of the round roller is designed to be smooth, it is convenient for the operator to pull the pulling rope to adjust the position of the clamping block.

[0014] Preferably, both the left and right sides of the lower cover are fixedly connected with two positioning rods that are symmetrically distributed front and back. A positioning groove adapted to the positioning rods is opened on the bottom of the upper cover.

[0015] Restricted by the positioning rod and the positioning groove, the upper cover can be accurately placed on the top of the lower cover, ensuring the adjustment of the position of the subsequent clamping block and realizing the fixation between the upper cover and the lower cover.

[0016] Preferably, the first heat dissipation holes are opened on the left and right sides of the lower cover, and the second heat dissipation holes are opened on the left and right sides of the upper cover.

[0017] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0018] First, the present utility model first places the soot blower body on the lower cover, and then pulls down the two handles. Under the action of the round roller and the pulling rope, the clamping blocks move relative to each other along the limiting groove on the guiding rod, compressing the return spring. When the distance between the two clamping blocks is the smallest, the upper cover is placed on the lower cover, and the positioning rod is inserted into the positioning groove. Then, the handles are released. Under the elastic force of the return spring, the clamping blocks on the left and right sides move away from each other and engage with the clamping grooves, that is, the installation of the upper cover is completed, and the soot blower body is fixed. When it is necessary to remove the soot blower body, pull down the handles again to disengage the clamping blocks from the clamping grooves, and then the upper cover can be lifted upward to release the fixation of the upper cover on the soot blower body, achieving the purpose of facilitating the disassembly and assembly of the soot blower body.

[0019] Second, when the present utility model fixes the soot blower body between the lower cover and the upper cover, through the first heat dissipation holes and the second heat dissipation holes, the heat generated during the operation of the soot blower body can be dissipated, achieving the purpose of heat dissipation. At the same time, under the action of the first dust-proof net and the second dust-proof net, dust can also be blocked. Description of the Drawings
