Description

Technical Field

[0001] The invention relates to the technical field of garbage incineration equipment, and in particular to a novel reciprocating water bath type incinerator slag discharger. Background Art

[0002] The incinerator slag remover is an important supporting equipment of the waste incineration system. Its main function is to drop the ash generated by the combustion section into the water-sealed slag remover through the slag dropping shaft, quickly cool it down with the help of the water seal and prevent dust. Then, a hydraulically driven scraper is used to push the cooled slag into the slag pit. A manhole door is provided on the top of the slag remover to facilitate manual slag discharge and internal cleaning when the furnace is shut down for maintenance or fault repair.

[0003] At present, the manhole doors of slag removers commonly found on the market are fixed with bolts, which are time-consuming and labor-intensive to disassemble and assemble, and the sealing gaskets are easily damaged if the bolts are disassembled multiple times. In addition, the slag remover body lacks a protective design against the return of slag and ash, and the water quality of the water seal system is easily contaminated by furnace flue gas and slag, resulting in severe long-term wear of the internal materials. Summary of the Invention

[0004] In view of the above-mentioned technical problems, the present invention provides a novel reciprocating water bath incinerator slag discharger.

[0005] The technical solution of the present invention is as follows: a novel reciprocating water bath incinerator slag discharger, comprising a casing, a slag pushing assembly arranged inside the casing, and a follower slag preventing assembly arranged inside the casing and connected to the slag pushing assembly; the casing is hollow inside, and comprises a horizontal section and an inclined section connected to the end of the horizontal section, the inclined section being arranged upwardly and obliquely relative to the horizontal section; legs are provided on the lower bottom surfaces of the horizontal section and the inclined section; a slag dropping pipe is provided on the side of the upper end surface of the horizontal section close to the inclined section, and a manhole door is movably hinged at the lower end of the outer wall of the horizontal section; a built-in water tank in communication with the interior of the horizontal section is provided at one end of the horizontal section away from the inclined section;

[0006] The slag pushing assembly includes a hydraulic cylinder arranged on the upper end surface of the horizontal section through a cylinder bracket and a scraper which is slidably engaged inside the horizontal section and rotatably engaged with the output end of the hydraulic cylinder; the end of the scraper away from the hydraulic cylinder is connected to a scraper which abuts against the bottom of the horizontal section;

[0007] The follower anti-slag assembly includes a transmission shaft arranged on the upper end surface of the horizontal section through a bearing seat and located at the rear end of the cylinder bracket, a crank arm sleeved on both ends of the transmission shaft and located on the inner side of the bearing seat at the corresponding position, a follower shaft rotatably clamped between the two crank arms and passing through the hinge point between the scraper and the output end of the hydraulic cylinder, and a follower baffle arranged on the outer side wall of the follower shaft and located above the scraper.

[0008] Furthermore, a hinge seat and several mounting pins are provided on the outer wall of the horizontal section; the manhole door is movably hinged to the hinge seat by a movable plug rod, and a mounting hole movably engaged with the mounting pin is provided on the manhole door; a locking assembly movably engaged with a side of the manhole door away from the movable plug rod is provided on the outer wall of the horizontal section; the locking assembly includes a first electric rod provided on the outer wall of the horizontal section, a pushing seat slidably engaged with the outer wall of the horizontal section and connected to the first electric rod, and several arc-shaped clamping seats equidistantly distributed on the side wall of the pushing seat and correspondingly engaged with each mounting pin;

[0009] Description: When in use, snap the manhole door onto the outer wall of the horizontal section. At this time, the mounting pin is movably plugged into the corresponding mounting hole. Then use the first electric rod to push the pushing seat close to the mounting pin, so that the arc-shaped seat is locked with the corresponding mounting pin, which is beneficial to improve the connection stability between the manhole door and the horizontal section.

[0010] Furthermore, each arc-shaped card seat is slidably engaged with a trigger seat abutting against the mounting pin at the corresponding position; a return spring abutting against the inner wall of the arc-shaped card seat is provided at one end of the trigger seat away from the mounting pin, and a rack is provided at the lower end of the outer wall of the trigger seat; a gear and a rotating disk are rotatably engaged with the inner part of the arc-shaped card seat through a rotating shaft, the gear and the rack are meshed and connected, and an arc-shaped pressure block is provided on the outer wall of the rotating disk;

[0011] Description: When the arc-shaped holder is close to the mounting pin, the trigger seat is squeezed and moves toward the inside of the arc-shaped holder. At this time, the meshing action of the rack and the gear is utilized to make the rotating disk drive the arc-shaped pressing block to rotate and press the manhole door tightly, further improving the convenience of opening and closing the manhole door and shortening the opening and closing time of the manhole door.

[0012] Furthermore, both ends of the movable rod are rotatably connected to slide seats that are slidably connected to the hinge seats at corresponding positions; a compression spring is provided inside the hinge seat to abut against the slide seats at corresponding positions; a sealing ring is provided on the inner wall of the manhole door to abut against the outer wall of the horizontal section;

[0013] Description: The sliding seat drives the movable rod to move toward the side close to the horizontal section under the action of the compression spring, and with the cooperation of the sealing ring, improves the sealing effect between the manhole door and the horizontal section.

[0014] Furthermore, one end of the inclined section away from the horizontal section is movably hinged to a discharge guide groove; the lower end of the outer side wall of the inclined section is movably hinged to a second electric rod movably hinged to the discharge guide groove;

[0015] Note: The second electric rod is used to push the discharge guide trough to rotate along the hinge point between it and the inclined section, so as to adjust the falling position of the ash and avoid ash accumulation affecting the normal progress of subsequent transfer work.

[0016] Furthermore, a spring sleeve connected to the scraper is provided inside the horizontal section. The scraper includes two sliding sleeves movably hinged to the top of the horizontal section and the upper end surface of the scraper, and a telescopic rod slidably engaged with the two sliding sleeves. Both ends of the telescopic rod are provided with push springs corresponding to the two sliding sleeves.

[0017] Note: By setting the spring sleeve, the scraper can always be in close contact with the bottom of the horizontal section, which is beneficial to improving the slag discharge efficiency.

[0018] Furthermore, the bottom of the horizontal section and the continuous inclined section are both provided with wear-resistant liners;

[0019] Note: Installing wear-resistant linings can help reduce friction loss of equipment and extend its service life.

[0020] Furthermore, an independent water tank connected to the built-in water tank is provided on the outer wall of the horizontal section, and a float valve is provided inside the independent water tank; a filter plate is provided on the side of the built-in water tank close to the inclined section;

[0021] Note: By setting up an independent water tank and a float valve, it is possible to replenish the water source for the built-in water tank while controlling the water seal level, thus avoiding turbidity of the water body caused by long-term water filling of the built-in water tank.

[0022] Furthermore, an overflow hole is provided on the outer side wall of the horizontal section, and the overflow hole is located at the connection between the slag falling pipe and the horizontal section;

[0023] Note: By setting the overflow hole, the water level can always be controlled at the connection between the slag dropping pipe and the horizontal section, which can effectively ensure the negative pressure environment inside the furnace and improve the working stability of the incinerator.

[0024] The working principle of the present invention is:

[0025] During use, water is poured into the built-in water tank, and the water source inside the built-in water tank can enter the casing. The waste incineration slag enters the casing through the slag dropping pipe, and is quickly cooled down and dust is prevented by the water seal. Then the hydraulic cylinder is used to push the scraper and scraper to move at the bottom of the casing, and the cooled slag is discharged from the end of the inclined section. At the same time, during the movement of the scraper, the crank arm and the follower shaft cooperate to make the follower baffle follow the scraper to effectively prevent the slag from being brought back with the scraper. When the manhole door needs to be closed, the manhole door is buckled on the outer wall of the horizontal section. At this time, the mounting pin is movably plugged into the corresponding mounting hole, and then the first electric rod is used to push the pushing seat close to the mounting pin, so that the arc-shaped clamping seat is clamped and locked with the corresponding mounting pin. When the arc-shaped clamping seat is close to the mounting pin, the trigger seat is squeezed and moves toward the inside of the arc-shaped clamping seat. At this time, the meshing action of the rack and the gear is used to make the rotating disk drive the arc-shaped pressure block to rotate and press the manhole door tightly.

[0026] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0027] First, the present invention has a reasonable structural design. By providing a follower anti-slag component, the follower baffle can move synchronously with the scraper, thereby effectively preventing the slag from being carried back with the scraper, avoiding the generation of secondary pollution, and also reducing the difficulty of equipment maintenance.

[0028] Secondly, the present invention provides a locking assembly at the connection between the manhole door and the horizontal section. When the arc-shaped holder approaches the mounting pin, the trigger seat is squeezed and moves toward the inside of the arc-shaped holder. At this time, the meshing action of the rack and the gear causes the rotating disk to drive the arc-shaped pressing block to rotate and press the manhole door tightly. This not only improves the sealing reliability between the manhole door and the horizontal section, but also improves the convenience of opening and closing the manhole door.

[0029] Third, the present invention can control the water seal level while replenishing the water source for the built-in water tank by setting an independent water tank and a float valve, thereby avoiding turbidity of the water body caused by long-term water filling of the built-in water tank; and the setting of the overflow hole can always control the water level line at the connection between the slag drop pipe and the horizontal section, effectively ensuring the negative pressure environment inside the furnace and improving the working stability of the incinerator.
