Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to an incinerator feeding system with a cooling function. Background Art

[0002] During the garbage incineration process, the garbage feed port is connected to the chute below, and the chute is connected to the incineration chamber of the grate, which causes the temperature in the chute to be relatively high. In order to prevent the temperature from being too high, a cooling device is often installed around the chute to reduce the temperature of the chute and prevent the inner wall of the chute from being damaged due to excessive temperature, or even the garbage in the feed hopper from being ignited due to high temperature.

[0003] For example, the prior art, publication number: CN103939916B, discloses a waste incinerator feeding device with water cooling and fire fighting functions, including a water cooling jacket and an inclined lower chute, which can be used to cool the lower chute. However, the prior art still has the following technical problems:

[0004] 1. Since the heating degree in the inclined lower chute is not uniform, and the water cooling jacket is only provided on one side of the lower chute, it is impossible to achieve uniform cooling around the entire lower chute;

[0005] 2. Since the amount of water stored in a single water-cooling jacket is fixed, after the temperature rises, the high-temperature water in the water-cooling jacket must be replaced frequently, resulting in a low utilization rate of the cooling water in a single water-cooling jacket. Utility Model Content

[0006] The utility model provides an incinerator feeding system with a cooling function, which can solve the problem of uneven cooling effect of the incinerator feeding system.

[0007] This application provides the following technical solutions:

[0008] The incinerator feeding system with cooling function comprises a feeding hopper and a material blocking and cooling part, the material blocking and cooling part is arranged at the lower part of the feeding hopper discharge port, the material blocking and cooling part comprises a rear wall and a material blocking mechanism, a plurality of rear walls and a material blocking mechanism are circumferentially surrounded to form a cooling channel, a water tank is arranged on the rear wall and the material blocking mechanism, and the water tanks are connected with each other by water pipes, a plurality of support rods and a plurality of isolation plates are arranged in the water tank, the isolation plates are provided with cooling holes and diversion holes, and a circulating water inlet hole, a circulating water outlet hole, a water inlet and a drainage hole are arranged at the bottom of the water tank.

[0009] Beneficial effects:

[0010] 1. Improve the utilization rate of cooling water in the water tank through internal circulation, and achieve uniform temperature in the circumferential direction of the cooling channel: multiple rear walls and a material retaining mechanism are circumferentially enclosed to form a cooling channel, and water tanks are provided on the rear wall and the material retaining mechanism, and the water tanks are connected with water pipes. By utilizing the cooling channel formed by the rear wall and the material retaining mechanism, the water tanks are connected with each other through the circulating water inlet hole and the circulating water outlet hole, so that internal circulation is achieved between the water tanks, and the heat and water in the water tank can be exchanged without adding cooling water from the outside, so that the temperature in the multiple water tanks arranged in the entire circumference is maintained within a certain same range, thereby ensuring that there is no uneven temperature of the rear wall and the material retaining mechanism, or avoiding the situation where the cooling water in the water tank needs to be frequently replaced because the temperature on only one side is too high;

[0011] 2. Through the coordination of external circulation and internal circulation, ensure that the water tank can be effectively cooled down when the internal circulation cannot cool down: use the circulating water inlet hole, circulating water outlet hole, water inlet and drain hole, connect cooling water through the water inlet, connect the water tank with the circulating water inlet hole and the circulating water outlet hole, and discharge water through the drain hole, so that the water tank can achieve the coordination of external circulation and internal circulation, ensure that the water temperature in the water tank is certain, and further evenly cool down when the temperature of the rear wall and the material blocking mechanism is too high.

[0012] 3. Provide a water tank structure that is relatively stable at high temperatures and has a good cooling effect: support rods are arranged in the water tank to maintain the structural strength of the water tank and prevent the water tank from expanding and bursting due to heat; the isolation plate in the water tank can isolate the water in the water tank so that the water separated by the isolation plate can disperse and absorb heat and maintain the structural strength of the water tank; and the cooling holes opened on the isolation plate can be used for the water in the water tank to fit the rear wall and the material retaining mechanism, further improving the cooling effect.

[0013] Furthermore, three isolation plates are arranged in the water tank, and 2 to 9 support rods are evenly arranged between the isolation plates and between the isolation plates and the inner wall of the water tank.

[0014] Beneficial effect: The isolation plate and the support rod are arranged in this way, which can ensure the structural strength of the water tank and prevent the water tank from rupturing due to the evaporation and expansion of water due to heat.

[0015] Furthermore, the cooling hole is located near the cooling channel, and is surrounded by the isolation plate and the inner wall of the water tank, and two cooling holes are arranged at the end of each isolation plate.

[0016] Beneficial effect: The cooling holes are arranged in this way so that the water flow can effectively fit the rear wall and the material retaining mechanism, so that the cooling effect is better during drainage or water circulation between water tanks.

[0017] Furthermore, four guide holes are evenly arranged in the middle of the isolation plate.

[0018] Beneficial effect: Such arrangement of the diversion holes can ensure a certain degree of circulation of the water inside the water tank.

[0019] Furthermore, steel pipes are provided in the circulating water inlet hole, the circulating water outlet hole, the water inlet and the drain hole. The steel pipes are located at one end of the water tank and fixed to the inner wall of the water tank, and the ends are open on both sides.

[0020] Beneficial effect: The steel pipe is fixed to the inner wall of the water tank and has openings on both sides of the ends, which can prevent the circulating water inlet hole, circulating water outlet hole, water inlet and drain hole from deforming due to the increase in water temperature in the water tank, and at the same time ensure the smooth drainage, water inlet and water circulation in the water tank.

[0021] Furthermore, it also includes a pushing mechanism, a grate and a slag remover feed hopper. The pushing mechanism is arranged below the material blocking mechanism. The pushing mechanism includes a material receiving platform and a pushing trolley. The grate is arranged on one side of the material receiving platform. The slag remover feed hopper is arranged at the discharging end of the grate.

[0022] Beneficial effect: the pushing mechanism can quickly push the garbage from the receiving platform into the grate for incineration after the blocking mechanism releases the garbage, and then the grate discharges the burned waste into the slag remover through the slag remover feed hopper.

[0030] Embodiment 1

[0031] like Figure 1 As shown, the incinerator feeding system with cooling function includes a feeding hopper 1 and a material blocking and cooling part 2, and also includes a pushing mechanism, a grate 7 and a slag remover feeding hopper 8. The pushing mechanism is arranged below the material blocking mechanism 22. The pushing mechanism includes a material receiving platform 6 and a pushing vehicle. The grate 7 is arranged on one side of the material receiving platform 6, and the slag remover feeding hopper 8 is arranged at the discharge end of the grate 7.

[0032] The material blocking and cooling part 2 is arranged at the lower part of the feed hopper 1, and the material blocking and cooling part 2 includes a rear wall 21 and a material blocking mechanism 22. Figure 1 , Figure 2 , Figure 3 As shown, a plurality of rear walls 21 and a material blocking mechanism 22 are circumferentially surrounded to form a cooling channel 3. In this embodiment, the rear wall 21 is a steel plate. A water tank 4 is arranged on the rear wall 21 and the material blocking mechanism 22, and the water tanks 4 are connected to each other by a water pipe 9. A plurality of support rods 41 and a plurality of isolation plates 42 are arranged in the water tank 4. The isolation plates 42 are provided with cooling holes 421 and guide holes 422. A circulating water inlet hole 43, a circulating water outlet hole 44, a water inlet 45 and a drainage hole 46 are arranged at the bottom of the water tank 4. In this embodiment, the circulating water inlet hole 43 and the circulating water outlet hole 44 have the same aperture diameter to facilitate uniform exchange of water flow. The aperture diameters of the water inlet 45 and the drainage hole 46 are both smaller than the aperture diameters of the circulating water inlet hole 43 and the circulating water outlet hole 44, and the aperture diameter of the water inlet hole is smaller than that of the circulating water inlet hole 43 and the circulating water outlet hole 44. The diameter of the drainage hole 46 can be specifically set as follows: the diameter of the circulating water inlet hole 43 and the circulating water outlet hole 44 is 57 mm, the diameter of the water inlet hole is set to 24 mm, and the diameter of the drainage port is set to 30 mm. This setting can help make the water inlet flow smaller than the water outlet flow, so as to take away the heat in the water tank 4. In addition, the circulating water inlet hole 43, the circulating water outlet hole 44, the water inlet 45 and the drainage hole 46 are all welded with a steel pipe 5. The steel pipe 5 is located at one end of the water tank 4 and is fixed to the top of the water tank 4. The two sides of the end are opened 51. The other end of the steel pipe 5 extends out of the water tank 4 to connect to the water pipe 9. The end of the steel pipe 5 set on the drainage hole 46 is welded with a flange, and a flange cover is bolted on the flange to connect to the drainage pipe 9 and close the drainage hole 46. Figure 5As shown, further, a water pump 10 can be provided at the circulating water inlet hole 43 and the water inlet 45 steel pipe 5, so that when no water enters the water inlet 45, the water pump 10 is utilized to accelerate the flow of water between the water tanks 4 so that heat is transferred, thereby avoiding the need for frequent replacement of cooling water in a single water tank 4 due to excessive temperature, thereby realizing internal circulation of water between the water tanks 4. At the same time, when water enters the water inlet 45, the water pump 10 connected to the steel pipe 5 provided on the water inlet is utilized to replace the water in all the water tanks 4 as a whole, thereby improving the efficiency of water replacement, and realizing external circulation when water is continuously introduced through the water inlet 45 and water is discharged through the drainage hole 46.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, three isolation plates 42 are provided in the water tank 4, and 2-9 support rods 41 are evenly provided between the isolation plates 42 and between the isolation plates 42 and the inner wall of the water tank 4. In this embodiment, the cooling holes 421 are located near the cooling channel 3, surrounded by the isolation plates 42 and the inner wall of the water tank 4, and two cooling holes 421 are provided at the end of each isolation plate 42. Four guide holes 422 are evenly provided in the middle of the isolation plate 42.

[0034] The material blocking mechanism 22 includes a material blocking plate 221, a rotating shaft 222, a material blocking base 223 and a mounting base; Figure 2 As shown, the material-blocking base 223 includes an upper slide groove and a lower mounting plate; a fixed plate is welded on the outer side wall of the upper slide groove, a rolling bearing is welded and installed on the fixed plate, and the rotating shaft 222 is installed in the rolling bearing; one end of the material-blocking plate 221 is welded to the middle part of the rotating shaft 222; the mounting base is welded to the lower mounting plate at a certain angle, and a hydraulic cylinder is installed on the side wall of the mounting base with bolts, and the power output shaft of the hydraulic cylinder is fixedly connected to the rotating shaft 222 through a conversion plate fixed to the shaft end of the rotating shaft 222, so that when the power output shaft of the hydraulic cylinder is extended, the conversion plate rotates around the rotating shaft 222 to close the material-blocking plate 221, and when the power output shaft of the hydraulic cylinder is retracted, the material-blocking plate 221 is opened; a water tank 4 is arranged on one side of the mounting base, and the water tank 4 has the same structure as the water tank 4 described above, and will not be described in detail here. In this embodiment, the lower mounting plate is a steel plate, and the upper slide groove is also welded from a steel plate.

[0035] Here’s how to use it:

[0036] According to the different water temperatures in the water tank 4, internal circulation and external circulation cooling methods are respectively adopted to ensure more effective and uniform cooling.

[0037] Internal circulation: water inlet 45 stops water inflow, and drainage hole 46 is blocked by flange to stop drainage. Figure 5As shown, the water pump 10 connected to the steel pipe 5 of the circulating water inlet hole 43 is started, and the water in the four circumferentially arranged water tanks flows rapidly counterclockwise between the water tanks through the water pipe 9 connected to the circulating water inlet hole 43 and the circulating water outlet hole 44 driven by the water pump 10, thereby realizing heat exchange of water between the water tanks, so that the water temperature in all water tanks 4 around the cooling channel 3 is basically the same.

[0038] External circulation: When the temperature in the water tank 4 is too high, because multiple water tanks 4 are arranged circumferentially in the cooling channel 3 and are all provided with circulating water inlet holes 43, circulating water outlet holes 44, water inlets 45 and drain holes 46, only the drain hole 46 of the water tank 4 with the highest water temperature is opened, and the water inlets 45 of the remaining water tanks 4 all start to take in cooling water through the external water pump 10, open the flange cover provided on the steel pipe 5 of the drain hole 46, and connect an external drain pipe, so that the water in all water tanks 4 is discharged through the drain hole 46 of the water tank 4 with the highest water temperature, thereby ensuring that the heat in the water tank 4 is fully exchanged and continuously cooled.

[0039] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
