Description

Technical Field

[0001] The utility model relates to the technical field of biomass carbonization, in particular to a discharging device for preparing biomass dry carbon. Background Technique

[0002] China has a long history of charcoal burning. The earliest carbonization device appeared in the form of a kiln. Generally, an earth kiln or a brick kiln was used as the reaction device. Biomass raw materials such as weeds, straws, dead branches, and fallen leaves were filled into the kiln. The heat required for the carbonization process was provided by the combustion of fuel in the kiln. Then the kiln was closed, and the biomass was smoldered in an oxygen-deficient environment and slowly cooled in the kiln to finally make charcoal. Biomass carbonization production is an important technical route for the development and utilization of renewable energy. However, the current technical devices in this regard are not ideal. Since the temperature of the carbonized material is relatively high, it is relatively easy for mechanical equipment to be damaged, deformed, or blocked during long-term high-temperature operation. Therefore, discharging is rather difficult. Most equipment is equipped with a screw discharger, which often cannot solve the problem of easy blockage due to high temperature, and there is a lot of dust during the discharging process.

[0003] Based on this, the utility model designs a discharging device for preparing biomass dry carbon to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a discharging device for preparing biomass dry carbon to solve the problems of easy blockage due to high temperature and a large amount of dust during the discharging process in the existing discharging equipment proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes an inner material pipe and an outer protection pipe. The inner material pipe is fixedly installed inside the outer protection pipe. One end of the inner material pipe extends outwards and is fixedly connected with a material receiving pipe. The bottom of the inner material pipe is fixedly connected with a hollowed-out railing. The bottom of the hollowed-out railing is fixedly connected with a dust collection cylinder. Air cylinders and guide cylinders are evenly distributed around the circumference of the outer wall of the inner material pipe. A pressing rod is slidably connected inside the guide cylinder. The end of the pressing rod is fixedly connected with a middle sliding shaft. An opening rod is rotatably connected to the outside of the inner material pipe. A middle sliding groove is provided in the middle of the opening rod. The middle sliding shaft is located in the middle sliding groove and the two are slidably matched. A cooling ring pipe is provided outside the inner material pipe. A spray head is provided on one side of the cooling ring pipe. The cooling ring pipe is located at the bottom end of the opening rod and the two are slidably connected. A blowing ring pipe is installed outside the outer protection pipe. The air cylinders are communicated with the blowing ring pipe.

[0006] As a further scheme of the utility model, the top of the material receiving pipe is fixedly connected with a square material feeding pipe. The bottom of the outer protection pipe is fixedly installed with support feet. A water outlet pipe is provided at the bottom of the outer protection pipe. A dust outlet window is opened at the bottom of the dust collection cylinder.

[0007] As a further scheme of the utility model, both the air cylinders and the dust collection cylinder are inclined downwards and their ends are arranged towards the center of the inner material pipe. The hollowed-out railing is an inclined railing.

[0008] As a further solution of the utility model, the cooling ring tube is located above the bottom end of the opening rod, and a ball head rod is fixedly connected to the inner side of the cooling ring tube. A connecting groove is opened in the middle of the opening rod, and the ball head rod is located in the connecting groove and the two are slidably matched.

[0009] As a further solution of the utility model, a water collecting ring is fixedly connected to the outer wall of one side of the outer protective tube near the lower end, and the side walls of the cooling ring tube are fixedly connected to extended water pipes. The extended water pipes are connected and fixed by straight water pipes, and an extended water pipe near the lower end is connected to the water collecting ring through a hose.

[0010] As a further solution of the utility model, a telescopic cylinder is fixedly installed on the inner side of the outer protective tube, and the movable end of the telescopic cylinder is fixedly connected to the extended water pipe of the cooling ring pipe at the lowermost end of the inner material pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model sprays coolant through the nozzle of the cooling ring tube to sprinkle on the outside of the inner material tube, so as to cool down the transmission environment and the material, avoid the burning of the high-temperature material after carbonization, and the spray cooling is relatively fast and comprehensive, and the carbonized material will not get wet after cooling through the inner material tube.

[0013] During the transmission process, the extrusion rod squeezes and feeds the material along the guide cylinder toward the center of the inner material tube, which plays the role of preliminary crushing and auxiliary feeding, pushes the material obliquely downward to avoid blockage and speed up material feeding; the extrusion rod squeezes, crushes and then retracts repeatedly, which is relatively simple and convenient, has a simple structure and is relatively durable.

[0014] During the transportation and extrusion rod crushing, high-speed airflow is introduced into multiple wind tubes through the blowing ring tube, so that the dust generated by the crushing and transportation is blown into the dust collecting tube through the hollow fence during the transportation process.

[0024] See also Figure 1-7 , the utility model provides a technical solution:

[0025] Working principle: The utility model receives the carbonized material into the inner material pipe 1 through the material receiving pipe 3, and the material falls under its own weight. At the same time, the cooling liquid is sprayed on the outside of the inner material pipe 1 through the nozzle 13 of the cooling ring pipe 12 to cool the transmission environment and the material to avoid the combustion of the high-temperature material after carbonization. The spray cooling is relatively fast and comprehensive, and the carbonized material will not get wet after cooling through the inner material pipe 1.

[0026] During the transmission process, the cooling ring tube 12 is moved downward, and the opening rod 10 is squeezed and contracted inward, thereby driving the extrusion rod 8 to extrude and feed the material along the guide tube 7 toward the center of the inner material tube 1, which plays a role in preliminary crushing and auxiliary feeding, and pushes the material obliquely downward to avoid blockage and speed up material feeding; the cooling ring tube 12 is moved back and forth to drive the opening rod 10 to open and close repeatedly, so that the extrusion rod 8 is squeezed, crushed and then closed repeatedly, which is relatively simple and convenient, and has a simple structure and is relatively durable.

[0027] It is relatively simple and convenient to drive the cooling ring pipe 12 to move forward and backward through the telescopic cylinder 24, and the cooling ring pipes 12 are fixed and connected to each other through the extended water pipe 22 and the straight water pipe 23, so that multiple cooling ring pipes 12 can be driven to move together at the same time. Different parts of the inner material pipe 1 can be cooled while moving. The extended water pipe 22 allows the telescopic cylinder 24 to be installed at a position away from the inner material pipe 1, thereby avoiding high-temperature operation.

[0028] When the transportation and extrusion rod 8 is broken, high-speed air flow is introduced into multiple air cylinders 6 through the blowing annular pipe 14, so that the dust generated during the appropriate transportation of the broken material is blown into the dust collection cylinder 5 through the hollow rail 4 during transportation. This is faster and more thorough than the automatic falling of the dust. Dust adhering to the surface and in the gaps can be quickly blown into the dust collection cylinder 5 with the assistance of wind force, thereby achieving dust-free discharging. The dust emission at the outlet is greatly reduced, the discharging working environment is improved, and it is beneficial to the health of personnel and the environment.

[0029] When the cooling annular pipe 12 moves back and forth, through the cooperation of the ball head rod 19 and the connecting groove 20, the cooling annular pipe 12 can smoothly pull back and open the opening rod 10, so that the opening rod 10 can be smoothly pushed and pulled back, making its operation smooth. When the opening rod 10 rotates downward and closes, the extrusion rod 8 is pressed down, and the middle sliding shaft 9 slides down in the middle sliding groove 11 to adapt to the movement of the opening rod 10 and the extrusion rod 8. The water after cooling is discharged from the water outlet pipe 17, and the carbonized dust is discharged through the dust outlet window 18.
