[0002] With the continuous acceleration of urbanization in my country, municipal solid waste incineration has become one of the mainstream methods of treatment. Currently, there are over a thousand waste-to-energy incineration plants in operation nationwide, with more than 5,000 sets of waste-to-energy incineration boilers installed, and the industry is still growing rapidly at a rate of about 15% per year.

[0003] The dynamic sealing between the reciprocating arc motion grate pusher and the furnace body in waste incinerators has become a long-standing technical problem that has plagued the global industry and remains unsolved due to the extreme operating conditions of high temperature, high motion, and high abrasion. Existing flexible rubber sealing solutions have serious shortcomings in terms of lifespan, reliability, and economy. Therefore, those skilled in the art have provided a graphite packing sliding plate seal for incinerator grate pushers to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a graphite packing slide seal for an incinerator grate pusher that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A graphite packing slide seal for an incinerator grate pusher includes a lifting lug flange. An outer furnace body connecting flange is fixedly connected to the rear end of the lifting lug flange. A movable mechanism is provided at the rear end of the outer furnace body connecting flange. A grate pusher is sealed inside the movable mechanism. Support mechanisms are provided on both sides of the rear end of the lifting lug flange. A connecting mechanism that cooperates with the two support mechanisms is provided on the side wall of the movable mechanism.

[0007] As a further optimization of this utility model, the movable mechanism includes a sealing ball sleeve fixedly connected to the rear end of the connecting flange of the outer furnace body, a second annular graphite packing root that cooperates with the connecting flange of the outer furnace body is provided at the front end of the sealing ball sleeve, a first annular sealing graphite packing root is provided on the inner wall of the sealing ball sleeve, and a movable component is provided on the inner wall of the sealing ball sleeve.

[0008] As a further optimization of this utility model, the movable component includes a sealing outer spherical sleeve that is movably connected to the inner wall of the sealing ball outer sleeve. A push rod guide sleeve that is fixedly sleeved to the side wall of the grate push rod is provided on the front side of the inner wall of the sealing outer spherical sleeve. A push rod sealing graphite packing that is fixedly sleeved to the side wall of the grate push rod is provided in the middle of the inner wall of the sealing outer spherical sleeve.

[0009] As a further optimization of this utility model, the connecting mechanism includes a compression spring plate fixedly sleeved to the side wall of the sealing outer spherical sleeve. The front ends of the compression spring plate are respectively fixedly connected to the two mounting tubes. Compression springs are fixedly installed on the inner walls of the two mounting tubes. Pressure plates fixedly connected to the mounting tubes are slidably installed on the inner walls of the mounting tubes. A fixing bolt threadedly connected to the rear end of the compression spring plate is rotatably passed through the rear end of the sealing outer spherical sleeve. A limit component is provided at the rear end of the compression spring plate.

[0010] As a further optimization of this utility model, the limiting component includes a guide graphite copper sleeve that slides through the inner wall of the compression spring plate, and the guide graphite copper sleeve is fixedly sleeved with the side wall of the grate pusher. An extrusion plate is fixedly sleeved on the side wall of the guide graphite copper sleeve, and an extrusion bolt that is threadedly connected to the rear end of the extrusion plate is rotatably provided with the extrusion bolt.

[0011] As a further optimization of this utility model, the support mechanism includes a mounting bracket fixedly connected to one side of the rear end of the lifting lug flange. A pin is fixedly passed through the side wall of the mounting bracket, and a hinge bolt is rotatably sleeved on the side wall of the pin. The other end of the hinge bolt slides through the mounting tube, the compression spring, and the pressure plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an active mechanism, the lifting flange is fixedly connected to the furnace body. By pushing the grate push rod, the grate push rod can drive the sealing outer spherical sleeve to move in an arc shape within the sealing outer spherical sleeve. During the movement of the sealing outer spherical sleeve, a first annular sealing graphite packing is provided on the inner wall of the sealing outer spherical sleeve, and a second annular graphite packing is provided at the front end of the sealing outer spherical sleeve, so that the grate push rod can form a sliding seal with the furnace body during the movement.

[0014] 2. In this utility model, by setting up an active mechanism and a support mechanism, and by adjusting the nut on the hinge bolt, the pressure plate's compression of the spring is adjusted, thereby achieving an arc seal between the sealing outer spherical sleeve and the sealing outer spherical sleeve when rotating in an arc. At the same time, by adjusting the compression bolt, the push rod sealing graphite packing achieves an axial seal when the push rod reciprocates with the grate push rod. This effectively achieves simultaneous sealing of three separate actions: reciprocating arc motion and vertical movement. Furthermore, by employing a push rod sealing graphite packing, a first annular sealing graphite packing, and a second annular graphite packing, the service life of the grate push rod and the furnace body seal is effectively improved, maintenance costs are reduced, and convenience is provided for maintenance and repair by the staff.

[0023] like Figure 1 - Figure 5As shown, the movable mechanism 2 includes a sealing ball sleeve 201 fixedly connected to the rear end of the outer furnace body connecting flange 4. A first annular sealing graphite packing 205 is provided on the inner wall of the sealing ball sleeve 201, and a second annular graphite packing 206 is provided at the front end of the sealing ball sleeve 201. This further improves the sealing effect of the sealing outer spherical sleeve 202 during movement and increases the overall service life of the device. The front end of the sealing ball sleeve 201 is provided with a second annular graphite packing 206 that mates with the outer furnace body connecting flange 4. The inner wall of the sealing ball sleeve 201 is provided with the first annular sealing graphite packing 205. The inner wall of the sealing ball sleeve 201 is movably connected to the sealing outer spherical sleeve 202. A push rod guide sleeve 204, which is fixedly fitted to the side wall of the grate push rod 6, is provided on the front side of the inner wall of the sealing outer spherical sleeve 202. A push rod sealing graphite packing 203 is provided in the middle of the inner wall of the grate push rod 6 and is fixedly sleeved on the side wall. A push rod sealing graphite packing 203 and a push rod guide sleeve 204 are provided between the grate push rod 6 and the sealing outer spherical sleeve 202, which can effectively improve the sealing performance when the sealing outer spherical sleeve 202 moves. The lifting lug flange 5 is fixedly connected to the furnace body. By pushing the grate push rod 6, the grate push rod 6 can drive the sealing outer spherical sleeve 202 to move in an arc shape in the sealing outer spherical sleeve 201. During the movement of the sealing outer spherical sleeve 202, a first annular sealing graphite packing 205 is provided on the inner wall of the sealing outer spherical sleeve 201, and a second annular graphite packing 206 is provided at the front end of the sealing outer spherical sleeve 201, which can make the grate push rod 6 form a sliding seal with the furnace body during the movement.

[0024] like Figure 1 - Figure 5As shown, the connecting mechanism 1 includes a spring plate 101 fixedly sleeved to the side wall of the sealing outer spherical sleeve 202. Mounting tubes 106 are fixedly connected to both sides of the front end of the spring plate 101. Springs 102 are fixedly installed on the inner walls of the two mounting tubes 106. Pressure plates 103 are slidably installed on the inner walls of the mounting tubes 106 and fixedly connected to them. A fixing bolt 107, threadedly connected to the rear end of the spring plate 102, rotatably passes through the rear end of the spring plate 101. A guide graphite copper sleeve 104 slidably passes through the inner wall of the spring plate 101, and the guide graphite copper sleeve 104 is fixedly sleeved to the side wall of the grate pusher 6. The side wall of the guide graphite copper sleeve 104 is fixedly... An extrusion plate 108 is fitted, and an extrusion bolt 105 is rotatably connected to the rear end of the sealing outer spherical sleeve 202. By adjusting the extrusion bolt 105, the push rod sealing graphite packing 203 and the grate push rod 6 reciprocate to achieve axial sealing. This effectively achieves simultaneous sealing of three separate actions: reciprocating arc motion and vertical movement. Furthermore, the use of push rod sealing graphite packing 203, first annular sealing graphite packing 205, and second annular graphite packing 206 effectively improves the service life of the grate push rod 6 and the furnace body seals, reduces maintenance costs, and provides convenience for maintenance and repair.

A nut is provided on the side wall of the hinge bolt 301. By rotating the nut, the compression of the spring 102 in the mounting tube 106 can be adjusted. The compression between the compression plate 108 and the spring plate 101 can be adjusted by using the compression bolt 105. This can improve the axial and arc sealing performance of the device. The other end of the hinge bolt 301 slides through the mounting tube 106, the spring 102 and the pressure plate 103. By adjusting the nut on the hinge bolt 301, the compression of the spring 102 by the pressure plate 103 can be adjusted, thereby achieving an arc seal between the sealing outer spherical sleeve 202 and the sealing outer spherical sleeve 202 when rotating in an arc.

[0026] It should be noted that, in the case of this incinerator grate pusher graphite packing sliding plate seal, the lifting flange 5 is fixedly connected to the furnace body. By pushing the grate pusher 6, the grate pusher 6 can drive the sealing outer spherical sleeve 202 to move in an arc shape within the sealing outer spherical sleeve 201. During the movement of the sealing outer spherical sleeve 202, a first annular sealing graphite packing 205 is provided on the inner wall of the sealing outer spherical sleeve 201, and a second annular graphite packing 206 is provided at the front end of the sealing outer spherical sleeve 201, which allows the grate pusher 6 to form a sliding seal with the furnace body during the movement.

[0027] By adjusting the nut on the hinge bolt 301, the pressure plate 103 adjusts the pressure of the spring 102, thereby achieving an arc seal between the outer spherical sleeve 202 and the outer spherical sleeve 202 when rotating in an arc. At the same time, by adjusting the compression bolt 105, the push rod sealing graphite packing 203 achieves an axial seal when it reciprocates with the grate push rod 6.
