Description

Technical Field

[0001] The utility model relates to the technical field of waste incineration treatment, in particular to an anti-caking ash bin. Background Technique

[0002] After domestic waste is completely burned in an incinerator, some will form fly ash, which enters the tail gas treatment system with the air flow. After being intercepted by a bag filter, it is transported to the ash bin for storage by a scraper conveyor and centrally treated harmlessly.

[0003] Vibrating ash discharge is usually used when discharging ash from the ash bin. A vibrator is installed on the side of the bottom of the ash bin. Through vibration, the fly ash is separated from the bin wall and then falls to the outlet of the ash bin, so as to achieve the effect of ash discharge. For a part of the fine dust, the friction force attached to the inner wall of the bin is relatively large, so it is difficult to achieve the purpose of separating from the bin wall through vibration; in addition, the characteristics of fly ash from domestic waste incineration are high silicon and calcium content, easy to absorb moisture in the air, and will form hard blocks after absorbing moisture. Therefore, after using the ash bin for a long time, a layer of fly ash layer is likely to accumulate in the bin wall near the outlet of the ash bin. If not cleaned in time, it will also cause the outlet of the ash bin to be blocked, resulting in unsmooth ash discharge. Content of the Utility Model

[0004] In order to overcome the defects existing in the prior art, the utility model provides an anti-caking ash bin to solve the above problems.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-caking ash bin, which includes an ash bin body, a conical outlet, a Roots blower, a heater, an air pipe and a hinge module;

[0006] The output port of the Roots blower is communicated with the input port of the heater, the output port of the heater is communicated with the input end of the air pipe, and the output end of the air pipe penetrates through the wall surface of the conical outlet and is communicated with the inside of the conical outlet;

[0007] One end of the lower side of the ash bin body is hinged to one end of the upper side of the conical outlet through a hinge module.

[0008] Preferably, it further includes an air-vapor plate, the air-vapor plate is arranged on the wall surface of the conical outlet, the input end of the air-vapor plate is communicated with the output end of the air pipe, and the output end of the air-vapor plate is located inside the conical outlet.

[0009] Optionally, the hinge module includes a first hinge block and a second hinge block.

Detailed Embodiments

[0019] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation on the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] As Figures 1-4 shown, an anti-caking ash bin includes an ash bin body 1, a conical outlet 2, a Roots blower 3, a heater 4, an air pipe 5, and a hinge module 6;

[0021] The output port of the Roots blower 3 is communicated with the input port of the heater 4, the output port of the heater 4 is communicated with the input end of the air pipe 5, and the output end of the air pipe 5 passes through the wall surface of the conical outlet 2 and is communicated with the inside of the conical outlet 2; the heater 4 is a tubular heater 4;

[0022] One end of the lower side of the ash bin body 1 is hinged to one end of the upper side of the conical outlet 2 through a hinge module 6.

[0023] In the anti-caking ash bin, after the Roots blower 3 is started, the high-pressure air can fluidize the dust in the ash bin, reduce the friction force of the dust adhering to the inner wall of the bin, so as to unload the ash more smoothly. At the same time, when the heater 4 is started, the high-pressure air generated by the Roots blower 3 can be heated, which can reduce the humidity of the dust inside the ash bin to a certain extent and avoid dust caking. In addition, the ash bin body 1 and the conical outlet 2 are hinged through the hinge module 6, so that the ash bin body 1 can be regularly opened to clean the fly ash layer accumulated on the inner wall of the conical outlet 2, ensuring that the conical outlet 2 will not be blocked and the ash unloading is smooth.

[0024] It is worth noting that, as Figure 1 shown, it further includes an air-vapor plate 7. The air-vapor plate 7 is arranged on the wall surface of the conical outlet 2. The input end of the air-vapor plate 7 is communicated with the output end of the air pipe 5, and the output end of the air-vapor plate 7 is located inside the conical outlet 2. Through the air-vapor plate 7, the hot air contacts the dust, which can achieve the effects of reducing the friction force and reducing the humidity, making the whole ash unloading process smoother. In addition, the air-vapor plate 7 is unidirectional, and the hot air will only flow out from the output end of the air-vapor plate 7, so that the situation of hot air blockage caused by the flow of dust will not occur. In this embodiment, the air-vapor plates 7 are evenly distributed along the circumferential direction of the wall surface of the conical outlet 2.

[0025] Optionally, as Figure 2As shown, the hinge module 6 includes a first hinge block 61 and a second hinge block 62. The first hinge block 61 is fixedly connected to one end of the lower side of the ash bunker body 1, and the second hinge block 62 is fixedly connected to one end of the upper side of the cone outlet 2. The first hinge block 61 and the second hinge block 62 are hinged to each other. The hinge module 6 further includes a rotating shaft that passes through both the first hinge block 61 and the second hinge block 62 to achieve the hinge connection. In this way, when the cone outlet 2 remains stationary, the ash bunker body 1 can be flipped relative to the cone outlet 2. In this solution, when the ash bunker body 1 is not flipped, the interior of the ash bunker body 1 communicates with the cone outlet 2. During ash discharge, the fly ash will flow from the ash bunker body 1 to the cone outlet 2 and then be discharged from the cone outlet 2.

[0026] Preferably, as Figure 3 and 4 shown, a locking seat 81 is provided at the other end of the lower side of the ash bunker body 1, and a connecting seat 82 is provided at the other end of the upper side of the cone outlet 2. The locking seat 81 and the connecting seat 82 cooperate to connect the other end of the lower side of the ash bunker body 1 to the other end of the upper side of the cone outlet 2. Through the cooperation of the locking seat 81 and the connecting seat 82, the other end of the lower side of the ash bunker body 1 and the other end of the upper side of the cone outlet 2 are locked, so that the ash bunker body 1 cannot be flipped relative to the cone outlet 2, ensuring that the interior of the ash bunker body 1 communicates with the interior of the cone outlet 2 to achieve ash discharge.

[0027] Specifically, the locking seat 81 is provided with a threaded hole 811, and the connecting seat 82 is provided with a through hole 821 that cooperates with the threaded hole 811. A locking screw 83 passes through the through hole 821 and is locked in the threaded hole 811 to fix the other end of the lower side of the ash bunker body 1 and the other end of the upper side of the cone outlet 2. In this embodiment, the threaded hole 811 is provided with a thread that cooperates with the locking screw 83 to facilitate locking the locking screw 83 in the threaded hole 811, and the diameter of the through hole 821 is larger than the diameter of the locking screw 83 to facilitate the locking screw 83 passing through.

[0028] It should be noted that the locking seat 81 is provided with a pin 84, and the connecting seat 82 is provided with a pin hole 85 that cooperates with the pin 84. After one end of the lower side of the ash bunker body 1 contacts the other end of the upper side of the cone outlet 2, by inserting the pin 84 into the pin hole 85, pre-positioning of the ash bunker body 1 and the cone outlet 2 can be achieved, aligning the threaded hole 811 of the locking seat 81 with the through hole 821 of the connecting seat 82, thus facilitating the locking screw 83 passing through.

[0029] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings. However, the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
