Description

Technical Field

[0001] The utility model relates to the technical field of furfural production, and more specifically to a slag discharge mechanism for a furfural production line. Background Art

[0002] The main raw materials for furfural production are agricultural and sideline products containing polypentose cellulose, including rice husks, cottonseed husks, tea oil shells, wheat straw, sorghum stalks, bagasse and corn cobs. Corn cobs have the highest polypentose content. These agricultural and sideline products are heated and pressurized under the action of acidic catalysts. The polypentoses are first hydrolyzed into pentoses, and furfural can be obtained by dehydrating the pentoses. In the production process of furfural, a large amount of furfural waste residue is generated.

[0003] At present, most furfural manufacturers in the same industry have the same slag discharge system. The auger in the system is used frequently when conveying materials. Regular disassembly and assembly of the auger or opening of the conveying pipe for cleaning will affect the operation of the production line. Failure to clean the conveying pipe will cause the inside of the conveying pipe to be easily blocked.

[0004] Therefore, there is an urgent need for a slag discharge mechanism for a furfural production line. Utility Model Content

DETAILED DESCRIPTION

[0020] A slag discharge mechanism for a furfural production line, combined with Figure 1 to Figure 2As shown, it includes a feed port 1, a first spraying mechanism 2, a dispersion roller 3, an auger 4, a dispersion box 5, a conveying pipe 6, a first motor 7, a lower gear 8, a transmission gear 9, an upper gear 10, a leg 11, a discharge port 12, a second spraying mechanism 13, an air pipe 16, an air pump 17, and a connecting chamber 18. The dispersion roller 3 includes a rotating shaft 31 and a stirring wing 32. The feed port 1 includes a fan disc 101, a second motor 102, and a fixing rod 103. The discharge port 12 includes a baffle 121 and a spring 122.

[0021] The feed port 1 is circular in the upper part and rectangular in the lower part. The feed port 1 includes a fixing rod 103 arranged horizontally at the top. The fixing rod 103 is connected to a second motor 102. The second motor 102 is connected to a circular fan disk 101. The fan disk 101 generates downward wind, which has the effect of air drying and deodorization. A waterproof shell is arranged outside the second motor 102, and the waterproof shell is conical to achieve preliminary bulking of the slag.

[0022] A first spraying mechanism 2 is arranged at the lower part of the feed port 1. The first spraying mechanism 2 comprises a spraying pipe and a plurality of spray heads arranged in the spraying pipe. The spraying pipe is connected to a water source.

[0023] The lower part of the feed port 1 is connected to a dispersion box 5, in which a horizontally arranged dispersion roller 3 is arranged. The dispersion roller includes a rotating shaft 31 horizontally arranged in the bulk material box, and a plurality of vertically arranged stirring wings 32 are connected to the rotating shaft 31 to break the material blocks that are bonded together to prevent clogging.

[0024] The lower left part of the dispersion box 5 is connected to the connecting chamber 18, and the connecting chamber 18 is connected to a horizontally arranged air pipe 16, and the air pipe 16 is connected to an air pump 17, and a filter is provided at the end of the air pipe 16, and the filter is inclined to the lower right direction to prevent the waste residue from being sucked into the air pipe 16. A deodorizer is connected to the air pipe 16 to reduce the odor during the slag discharge process.

[0025] A conveying pipe 6 having a length greater than that of the dispersion box 5 is connected below the connecting cavity 18, and a downward discharge port 12 is arranged at the right end of the conveying pipe 6. An auger 4 is arranged in the conveying pipe 6, and a first motor 7 is connected to the left end of the auger 4.

[0026] The first motor 7 is provided with a lower gear 8 , the upper part of the lower gear 8 is meshed with a transmission gear 9 , the upper part of the transmission gear 9 is meshed with an upper gear 10 , and the upper gear 10 is connected to the rotating shaft 31 of the dispersion roller 3 , and the dispersion roller and the auger 4 are driven to move by the first motor 7 .

[0027] The portion of the delivery pipe 6 that is not connected to the connecting cavity 18 is provided with a second spraying mechanism 13 to clean the auger 4 and the delivery pipe 6 . The second spraying mechanism 13 has the same structure as the first spraying mechanism 2 .

[0028] A pair of legs 11 are provided at the lower part of the delivery pipe 6 , and the legs 11 support the delivery pipe 6 so as to keep it away from the ground to a suitable height.

[0029] An inclined baffle 121 is arranged in the discharge port 12 , and a spring 122 is connected between the baffle 121 and the wall of the discharge port 12 , so that the discharge port 12 is in a closed state when there is no waste residue.

[0030] When the utility model is actually used, the waste slag enters the mechanism from the feed inlet, and is crushed once at the waterproof shell of the second motor. When passing through the fan blade disk, the second motor drives the fan blades to rotate to generate wind force, and the waste slag falls under the dual effects of gravity and wind force. After the waste enters the dispersion box, it is dispersed and crushed again under the action of the dispersion roller, and then when it enters the connecting cavity, a part of the airflow in the mechanism is sucked away by the air pipe to prevent the air pressure in the mechanism from being too high, and at the same time it plays a role in reducing odor. After the waste enters the conveying pipe, the auger drives the waste to move to the discharge port, presses down the baffle, and the spring contracts, and the waste falls out of the discharge mechanism. After the discharge is completed, the baffle is reset under the action of the spring to block the discharge port, preventing the waste adhering in the mechanism from emitting odor and polluting the environment.

[0031] When cleaning is required, the nozzle of the first spraying mechanism sprays water into the dispersion box to achieve cleaning, and at the same time cleans the left part of the conveying pipe directly below; the nozzle of the second spraying mechanism sprays water to the right part of the conveying pipe to clean it, avoiding the tediousness of removing the auger and opening the conveying pipe.
