[0002] A biomass gasifier is a device that can convert biomass into combustible gas (such as gas, steam, etc.). This device is usually composed of a furnace, a combustion chamber, a gasifier, a filter, etc. It can gasify biomass materials such as wood, straw, and branches, and convert them into usable gas energy. When using a biomass gasifier, the biomass material needs to be evenly distributed to ensure the gasification effect and the normal operation of the equipment. However, the biomass gasifier distribution device is a device for adding materials to the biomass gasifier.

[0003] At present, most of the biomass gasifier charging devices use rotary charging. However, this type of charging has a small diameter. When charging a large biomass gasifier, it is easy to cause damage to the rotary charging equipment, thereby reducing the safety and life of the charging device. Therefore, we propose a multi-row tube uniform charging device for a biomass gasifier to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a biomass gasifier multi-row tube uniform distribution device, comprising a transition bin, a top surface center of the transition bin is inlaid with a material injection pipe, and a bottom surface of the transition bin is provided with a plurality of distribution holes;

[0006] The inner cavity of each material distribution hole is provided with a material guiding component, and the top surface of the transition bin and one side of the material injection pipe are inlaid with a monitoring component.

[0008] Preferably, the material guiding assembly comprises a material guiding pipe arranged in the inner cavity of the material distributing hole, the bottom end of the material guiding pipe is connected to a feeding pipe, and the middle part of the feeding pipe is connected in series with a feeding valve.

[0009] Preferably, the outer diameter of the top end of the material guiding tube is the same as the inner diameter of the material distributing hole.

[0010] Preferably, the material guiding tube is in a frustum shape.

[0011] Preferably, the monitoring component includes a positioning tube embedded in the top surface of the transition bin, and a level meter is inserted into the inner cavity of the positioning tube.

[0015] The multi-row tube uniform material distribution device of the biomass gasifier can be connected to an external pipeline through the injection pipe through the transition bin, so that the staff can inject materials into the transition bin conveniently, and can also provide space for opening multiple material distribution holes, and then the multiple material distribution holes distributed in a circular array can facilitate the staff to install corresponding material guide components. When the gasifier reaches the carbon discharge condition, the multiple material guide components are opened to guide the materials stored in the transition bin to be discharged and then added to the biomass gasifier. The whole process does not require a power device to achieve the purpose of continuous and uniform feeding. In addition, the problem of uneven gasification of the gasifier can be effectively solved by opening and closing the material guide components.

[0023] Through the transition bin 1, an external pipeline can be connected through the injection pipe 2, so that the staff can inject materials into the transition bin 1 conveniently, and a plurality of distribution holes 3 can be provided with space for opening. Then, through the plurality of distribution holes 3 distributed in a circular array, the staff can install the corresponding material guide components 4 conveniently. When the gasifier reaches the carbon discharge condition, the plurality of material guide components 4 are opened, so that the materials stored in the transition bin 1 can be discharged and then added to the biomass gasifier. The whole process does not require a power device to achieve the purpose of continuous and uniform feeding. In addition, the opening and closing of the material guide component 4 can effectively solve the problem of uneven gasification of the gasifier. The remaining raw materials in the transition bin 1 can be monitored through the monitoring component, so that the staff can replenish the materials in the transition bin 1 in time.

[0024] See also Figure 3 , Figure 4 The material guide assembly 4 includes a material guide pipe 41 disposed in the inner cavity of the material distribution hole 3, the bottom end of the material guide pipe 41 is connected to a feeding pipe 42, a feeding valve 43 is serially connected to the middle of the feeding pipe 42, the outer diameter of the top end of the material guide pipe 41 is the same as the inner diameter of the material distribution hole 3, and the material guide pipe 41;

[0025] Through the material guide pipe 41 in the material guide assembly 4, it can be installed in the inner cavity of the material distribution hole 3, and the feeding pipe 42 can be installed. Then, through the feeding pipe 42, the feeding valve 43 can be installed in series. When the material stored in the transition bin 1 needs to be discharged, the feeding valve 43 is opened at this time, so that the material in the transition bin 1 can be introduced into the feeding pipe 42 through the conical material guide pipe 41, and then can be added to the gasifier.

[0026] See also Figure 1 , Figure 3 The monitoring component includes a positioning tube 5 embedded in the top surface of the transition bin 1, and a material level meter 6 is inserted into the inner cavity of the positioning tube 5;

[0027] Through the positioning tube 5 in the monitoring component, it can be embedded in the top surface of the transition bin 1 and the material level meter 6 can be installed. Then, through the material level meter 6, the remaining raw materials in the transition bin 1 can be monitored, so that the staff can replenish the materials in the transition bin 1 in time.

[0028] See also Figure 1 , Figure 3 The main view shape of the transition bin 1 is a cone-shaped column, which can make the top of the material stored in the transition bin 1 conical, thereby facilitating the downward discharge of the material.

[0029] During operation, the transition bin 1 can be connected to an external pipeline through the injection pipe 2, so that the staff can inject materials into the transition bin 1 conveniently, and multiple distribution holes 3 can be provided with space for opening. Then, through the multiple distribution holes 3 distributed in a circular array, the staff can install the corresponding material guide components 4 conveniently. When the gasifier reaches the carbon discharge condition, the multiple material guide components 4 are opened, so that the materials stored in the transition bin 1 can be discharged and then added to the biomass gasifier. The whole process does not require a power device to achieve the purpose of continuous and uniform feeding. In addition, the opening and closing of the material guide component 4 can effectively solve the problem of uneven gasification of the gasifier. The remaining raw materials in the transition bin 1 can be monitored through the monitoring component, so that the staff can replenish the materials in the transition bin 1 in time.

[0030] The material guide pipe 41 in the material guide component 4 can be installed in the inner cavity of the material distribution hole 3, and the feeding pipe 42 can be installed. Then, the feeding valve 43 can be installed in series through the feeding pipe 42. When the material stored in the transition bin 1 needs to be discharged, the feeding valve 43 is opened at this time, so that the material in the transition bin 1 can be introduced into the feeding pipe 42 through the frustum-shaped material guide pipe 41, and then can be added to the gasifier. The positioning tube 5 in the monitoring component can be embedded in the top surface of the transition bin 1, and the material level meter 6 can be installed. Then, the material level meter 6 can be used to monitor the remaining raw materials in the transition bin 1, so that it is convenient for the staff to replenish the material in the transition bin 1 in time. Since the main appearance shape of the transition bin 1 is a cone, the top of the material stored in the transition bin 1 can be conical, which makes it convenient to discharge the material downward.

[0031] In summary, the device can deliver materials into the gasifier through the material guide component 4 at the bottom of the transition bin 1, and a certain number of material guide components 4 can be set according to the diameter of the furnace surface. At the same time, the material in the transition bin 1 is monitored by the material level meter 6. Under normal use, multi-point feeding is carried out through the material guide component 4 under the transition bin 1. The material guide component 4 is in a normally open state. When the gasifier reaches the carbon discharge conditions, the carbon discharge equipment is started, and the material falls accordingly. The purpose of continuous and uniform feeding is achieved without the need for a power device. In addition, the problem of uneven gasification in the gasifier can be effectively solved by opening and closing the material guide component 4.
