Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slag removers, in particular to a slag remover door structure. Background Art
[0002] During the waste incineration process, the waste slag after high-temperature combustion needs to be cooled by water injection in the slag remover and then pushed to the designated storage location. Due to long-term high temperature and water erosion, the inside of the slag remover is prone to rust. In order to prevent the slag remover from being damaged due to internal rust and causing leakage of high-temperature waste slag and wastewater, it is necessary to regularly inspect the inside of the slag remover to ensure the safe operation of the slag remover.
[0003] The slag remover maintenance port is the only maintenance passage for entering and exiting the slag remover. In order to facilitate the entry of maintenance personnel, the slag remover maintenance door must not only have good sealing performance but also be easy for maintenance personnel to open and close.
[0004] The existing inspection doors have the following problems:
[0005] 1. Inspection doors generally use single-sided hinges as their rotating mechanism, which results in greater friction when the inspection doors are opened and closed, making it difficult for maintenance personnel to open and close the inspection doors.
[0006] 2. The inspection door is locked with a latch, which includes a wedge and a matching part fixed on the inspection door. Each time the inspection door is closed, the wedge needs to be hammered into the matching part to make the inspection door closed and sealed. When opening the inspection door, the wedge needs to be hammered to make it withdraw from the matching part before the inspection door can be opened, making it difficult to open and close the door and wasting time and energy for the maintenance personnel.
[0007] 3. In order to ensure better sealing and corrosion resistance, the inspection door is generally made of a whole piece of thicker steel material, which is heavy and makes it difficult to open and close the door. In addition, the inspection door has a whole-plate structure, which leads to high maintenance and replacement costs and poor economic efficiency. Utility Model Content
[0008] The utility model provides a slag remover door structure, which can solve the problem of difficulty in opening and closing the slag remover door.
[0009] The present application provides the following technical solution: a slag remover door structure, comprising a slag remover, a door body, a rotating mechanism and a locking mechanism, wherein a plurality of locking mechanisms are arranged on the slag remover housing in the circumferential direction of the inspection port of the slag remover, one arm of the rotating mechanism is rotatably arranged at one side of the inspection port, and the other arm of the rotating mechanism is fixedly connected to the middle part of the door body;
[0010] The rotating mechanism includes an n-shaped shaft and a rotating support. The rotating support is fixed on one side of the slag remover inspection port. One arm of the n-shaped shaft is rotatably connected to the rotating support, and the other arm of the n-shaped shaft is fixedly connected to the middle of the door body.
[0011] Technical principle: 1. Torque = lever arm × force. When the torque is constant, the larger the lever arm, the smaller the force used.
[0012] Beneficial effects:
[0013] 1. A locking mechanism is provided on the slag remover casing around the inspection port of the slag remover, which can ensure the airtightness of the inspection door on the inspection port.
[0014] 2. The rotating mechanism is arranged on one side of the inspection opening, and the middle part of the door body is fixedly connected to the rotating mechanism: a better rotating door opening effect can be ensured.

One arm of the n-shaped shaft is rotatably connected to the rotating support, and the other arm of the n-shaped shaft is fixedly connected to the middle part of the door body: when the n-shaped shaft rotates, the door does not rotate relatively, thereby reducing the friction between the door and the n-shaped shaft, which is more conducive to the opening and closing of the door. The n-shaped shaft is fixed at the middle part of the door body, rather than the side of the door as in the prior art, which increases the rotational force arm of the door. When the torque of the door remains unchanged, the force used to open and close the door is correspondingly reduced, making it more labor-saving to open and close the door.
[0016] Further: the rotating support includes a support plate and two mounting plates fixed on one side of the support plate, the two mounting plates are provided with mounting holes, a lubrication hole is provided on the top of the mounting plate, and a lubrication device is arranged in the lubrication hole.
[0017] Beneficial effects: The mounting plate is provided with mounting holes for mounting the n-shaped shaft; the lubrication device arranged in the lubrication hole can be used to inject lubricating oil into the mounting plate, thereby reducing the friction coefficient between the n-shaft and the mounting plate, making the friction force smaller when opening and closing the door, and saving more physical effort for the maintenance personnel.
[0018] Furthermore, an annular boss is provided in the middle of one arm of the n-shaped shaft, an external thread is provided at the end, and a connecting rod is provided at the other end. The end of the connecting rod is provided with an external thread. The diameter of the connecting rod is smaller than the diameter of the n-shaped shaft, and the connecting rod is fixedly connected to the middle of the door body.
[0019] Beneficial effects: The annular boss can be used to clamp the N-shaped shaft on the rotating support, and the external thread set at the end can be used to set a nut to fix the N-shaped shaft on the rotating support; the connecting rod diameter is smaller than the N-shaped shaft diameter, which can be used to utilize the cooperation between the connecting rod and the reinforcement rib, and the inspection door and the N-shaped shaft are fixed by the external thread installation nut set at the end of the connecting rod.
[0020] Furthermore, the door body includes a rectangular groove, in which a plurality of reinforcing ribs are arranged transversely and longitudinally, the middle of the transverse reinforcing rib is protruding and has a circular hole, and a plurality of through holes are arranged on the rectangular groove between the reinforcing ribs.
[0021] Beneficial effects: The reinforcing ribs in the rectangular groove can be used to improve the structural strength of the door, and the circular holes opened on the transverse reinforcing ribs can be used to install the door on the n-shaped shaft; the multiple through holes opened on the rectangular groove between the reinforcing ribs can be used to install a wear-resistant plate at the bottom of the rectangular groove.
[0022] Furthermore, a wear-resistant plate is fixedly installed at the bottom of the rectangular groove.
[0023] Beneficial effect: The wear-resistant plate can ensure that the inspection door still has good wear resistance when the whole plate structure is not used, and the wear-resistant plate can be quickly replaced after it is damaged, saving the maintenance and repair costs of the inspection door.
[0024] Furthermore, a mounting platform is circumferentially arranged at the top of the rectangular groove, and a plurality of tightening strips are arranged on the mounting platform.
[0025] Beneficial effects: The mounting platform can be used to install the tightening strip, and can also be used to assist in sealing the inspection port when the inspection door is closed; the tightening strip can be used to lock the door with the locking block and the locking bolt.
[0026] Furthermore, the locking mechanism includes a supporting ear seat, a rotating shaft, a locking block and a locking bolt. The supporting ear seat is fixed on the slag remover casing around the slag remover inspection port. The locking block is rotatably connected to the supporting ear seat by the rotating shaft. A threaded through hole is provided in the middle of the locking block, and the locking block is threadedly connected to the locking bolt.
[0027] Beneficial effect: When the locking block rotates around the rotating shaft on the supporting ear seat, the locking bolt can be used to fix the locking block under the locking block, thereby locking the inspection door; when the door needs to be opened, only the locking bolt needs to be loosened. Compared with the existing technology of using wedges and clamping blocks, it is more convenient and quick, saves the maintenance worker's physical strength in opening and closing the inspection door, improves the door opening efficiency, and ensures a better sealing effect of the inspection door.
[0028] Furthermore, a handle is provided on the rectangular groove.
[0029] Beneficial effect: The handle can be used to open and close the door, thereby improving the efficiency of opening and closing the door. BRIEF DESCRIPTION OF THE DRAWINGS
