Description

Technical Field

[0001] This utility model relates to the technical field of biomass boilers, and in particular to a fully enclosed biomass dust-free ash system. Background Technology

[0002] Biomass boilers generate a large amount of ash after combustion, which needs to be discharged through the grate and then transported away by ash trucks. For example, patent application number CN202321512373.8 discloses a high-efficiency ash discharger for boilers. This patent can guide the discharged ash by setting a ash guiding component, so that the discharged ash is directly loaded into the truck bed of the transport vehicle. By reducing the operation process, the ash discharge efficiency is improved. The bearing trough plate can bear the ash, the ash guiding trough plate can guide the ash, and the positioning support block can support the ash guiding trough plate with the help of the vehicle. By setting a drive component as a power source to drive the ash tamping rod to move, it replaces manual labor to unclog the ash discharge pipe and avoids injury to workers in a high-level environment. The bending of the tamping rod can increase the cleaning diameter of the ash discharge pipe, thereby improving the cleaning effect.

[0003] The existing slag transfer method generates a large amount of dust, mainly because fine ash particles are raised during the transfer process, which can cause workers to inhale the dust and endanger their safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fully enclosed dust-free ash and slag system for biomass, so as to solve the problem of dust generation when ash and slag from biomass boilers are transferred to slag trucks in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed biomass dust-free ash and residue-free system, comprising...

[0006] The slag collection cylinder has a spiral conveying pipe installed on one side wall;

[0007] The electric valve pipe is installed on the lower end pipe of the slag collection cylinder;

[0008] The cover has a through hole that penetrates the cover, and the lower end of the electric valve pipe is located on the cover and communicates with the through hole;

[0009] The water supply pipe is ring-shaped, with several spray heads installed on the inner wall and connecting pipes installed on the outer wall. The water supply pipe is mounted on the cover in a height-adjustable manner.

[0010] The dust cover has one end seamlessly connected to the opening of the cover and the other end seamlessly connected to one end of the ring-shaped water supply pipe.

[0011] Several suction tubes are installed on a dustproof cloth cover, and the suction tubes pass through the dustproof cloth cover.

[0012] Preferably, the lower end wall of the water supply pipe is provided with rubber plates at the recesses corresponding to the upper end of the slag truck compartment.

[0013] Preferably, the cover is provided with a number of lifting cylinders, and the output end of the lifting cylinder is fixedly connected to a crossbeam plate, which is fixedly connected to a water supply pipe.

[0014] Preferably, the inner wall of the dust cover is provided with a waterproof coating.

[0015] The beneficial effects of adopting the above technical solutions are:

[0016] This application uses a lifting cylinder 51 to drive the water supply pipe 60 to move vertically, so that the water supply pipe 60 can surround the opening end of the dump truck. Then, the spiral conveyor pipe 20 sends the ash and slag into the slag collection cylinder 10, so that the ash and slag in the slag collection cylinder 10 falls through the electric valve pipe 30. During this process, a large amount of dust will be generated. At this time, the vacuum cleaner connected to the suction pipe 71 will suck away the dust. After the material is unloaded, the spray head 61 on the water supply pipe 60 sprays water mist, so that the water mist can be sprayed on the surface of the ash and slag, avoiding dust generation when the vehicle moves.

[0018] Figure 2 This is a schematic diagram of some components of this utility model.

[0019] Figure 3 This is a schematic diagram of the water supply pipe of this utility model.

[0020] The components include: slag collection cylinder 10, spiral conveying pipe 20, electric valve pipe 30, cover 40, through hole 41, crossbeam plate 50, lifting cylinder 51, water supply pipe 60, spray head 61, connecting pipe 62, rubber plate 70, air suction pipe 71, and dustproof cloth cover 80. Detailed Implementation

[0021] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3 In this first embodiment, a fully enclosed biomass dust-free ash system includes...

[0023] The slag collection cylinder 10 has a spiral conveying pipe 20 installed on one side wall;

[0024] Electric valve pipe 30 is installed on the lower end pipe of slag collection cylinder 10;

[0025] The cover 40 has a through hole 41 that penetrates the cover 40, and the lower port of the electric valve pipe 30 is disposed on the cover 40 and communicates with the through hole 41.

[0026] The water supply pipe 60 is ring-shaped. Several spray heads 61 are provided on the inner side wall of the water supply pipe 60 and a connecting pipe 62 is provided on the outer side wall. The water supply pipe 60 is mounted on the cover 40 in a height-adjustable manner.

[0027] The dust cover 80 has one end seamlessly connected to the opening end of the cover 40, and the other end seamlessly connected to one end of the annular water supply pipe 60.

[0028] Several suction pipes 71 are provided on the dustproof cloth cover 80, and the suction pipes 71 penetrate the dustproof cloth cover 80.

[0029] This embodiment is implemented as follows:

[0030] When in use, the water supply pipe 60 moves downward so that it can be aligned with the upper end of the slag truck compartment. Then, the spiral conveyor pipe 20 can send the ash and slag into the slag collection cylinder 10. The ash and slag then fall through the electric valve pipe 30. During the falling process, a large amount of dust will be generated. At this time, the vacuum cleaner connected to the dust suction pipe 71 can suck up the dust. When enough ash and slag have fallen, the electric valve pipe 30 is closed. At this time, the spray head 61 on the water supply pipe 60 sprays water mist, which wets the surface of the ash and slag in the compartment. The connecting pipe 62 of this application can be connected to an external water pump.

[0031] The advantage of this application over the prior art is that it can prevent dust leakage when ash is transferred to the slag truck.

[0032] Please see Figure 1 Rubber plates 70 are respectively installed on the lower end wall of the water supply pipe 60 at the recessed part of the upper end of the slag truck compartment.

[0033] The rubber plate 70 can be inserted into the recess at the upper end of the dump truck's compartment, which can completely seal it and prevent dust from leaking out.

[0034] Please see Figure 1 , 2 The cover 40 is equipped with several lifting cylinders 51. The output end of the lifting cylinder 51 is fixedly connected to a crossbeam plate 50, and the crossbeam plate 50 is fixedly connected to the water supply pipe 60.

[0035] The lifting cylinder 51 can drive the crossbeam plate 50 to move vertically, which in turn drives the water supply pipe 60 to move vertically.

[0036] Please see Figure 1 The inner wall of the dust cover 80 is provided with a waterproof coating.

[0037] By applying a waterproof coating to the inner wall of the dust cover 80, the dust cover 80 can be prevented from getting wet.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
