Description

Technical Field

[0001] The utility model relates to the technical field of coconut shell drying, in particular to a coconut shell activated carbon stewing and baking machine. Background Art

[0002] The production process of coconut shell activated carbon includes the steps of collecting coconut shells, processing coconut shells, crushing coconut shells, pre-treating coconut shell particles, carbonizing coconut shells and activating. The process seems simple, but it contains many details. Among them, coconut shells will form coconut shell particles after being crushed. Coconut shell particles are the raw materials of coconut shell activated carbon. Before carbonization, the moisture inside the coconut shell particles will be removed to facilitate the detailed control of carbonization temperature and carbonization time in the subsequent carbonization process.

[0003] At present, the dehydration pretreatment of coconut shell particles adopts indirect heating method, and the equipment used is also varied, such as ovens, microwave ovens and other general equipment. When these general equipments are used to stew and bake coconut shell particles, the coconut shell particles will pile up together, resulting in poor drying consistency, long drying time, and energy waste. These problems are difficult to solve.

[0004] In view of this, a coconut shell baking machine for preparing activated carbon is designed to pre-treat and remove moisture from coconut shell particles, thereby improving the drying consistency of coconut shell particles, shortening the drying time, and reducing energy loss. Utility Model Content

[0005] The utility model aims to provide a coconut shell activated carbon stewing machine to solve the problems described in the background technology.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A coconut shell activated carbon stewing and roasting machine, comprising a hot air supply mechanism, and at least two mounting plates arranged horizontally with an interval between the upper and lower parts, the two mounting plates adjacent to each other are fixedly connected by a second support frame, a horizontally placed cylinder is also arranged on the mounting plate, a spiral blade with a hollow center is arranged on the inner wall of the cylinder, a rotating overhead component and a rotating drive mechanism are also fixedly arranged on the mounting plate, the bottom of the cylinder is suspended by the rotating overhead component, so that the cylinder rotates around the horizontal central axis on the rotating overhead component, the outer wall of the cylinder is connected to the rotating drive mechanism, and a connecting pipe is rotatably sleeved on the outer walls of the two ends of the cylinder, and the bottom of the connecting pipe is also connected by a The first support frame is fixedly installed on the mounting plate, and each cylinder is connected to the upper and lower adjacent cylinders through a curved pipe, so that several cylinders are connected in series in a "wave shape", and the pipe mouth of the curved pipe is fixedly connected to the connecting pipe, and a feed pipe is fixedly connected to the connecting pipe at one end of the uppermost cylinder not connected to the curved pipe, and the other end of the feed pipe extends obliquely upward, and a blind pipe is fixedly connected to the connecting pipe at one end of the lowermost cylinder not connected to the curved pipe, and a discharge hopper is provided at the bottom of the blind pipe, and an air inlet pipe is penetrated through the upper end of the curved pipe and the blind end wall of the blind pipe, the inlet end of the air inlet pipe is connected to the hot air supply mechanism, and the outlet end of the air inlet pipe blows air along the central axis of the cylinder.

[0008] When using the above scheme, coconut shell particles are added from the feed pipe, and the coconut shell particles slide down the feed pipe into the topmost cylinder. With the action of the rotating drive mechanism, the cylinder rotates, and the coconut shell particles are transported unidirectionally by the hollow spiral blades inside the cylinder. When the coconut shell particles are transported to the end of the cylinder, the coconut shell particles fall from the bend to the cylinder of the next layer until they are transported to the blind pipe and discharged from the discharge hopper at the bottom of the blind pipe.

[0009] In this process, the hot air supply mechanism continuously introduces hot air into the air inlet pipe. The hot air passes through the hollow part of the central axis of the cylinder and flows through the entire circular tube, so that the entire circular tube is evenly heated. With the help of the spiral blades in the cylinder, the coconut shell particles are stretched, stretched, moved, and rolled, thereby avoiding the accumulation of coconut shell particles and increasing the heating area of ​​the coconut shell particles. Each coconut shell particle can get the time to contact with the hot air, thereby improving the drying consistency and shortening the drying time.

[0010] Through the design of circular tubes distributed up and down and the connection method of "wave-shaped" series connection, combined with the blowing direction of the hot air pipe, on the one hand, the length of the cylinder is increased on a limited land area, and the increased length provides sufficient time for stewing and baking, realizing the functions of continuous feeding and continuous discharging. On the other hand, the hot air at the bottom layer can continue to be used to heat the coconut shell particles in the upper cylinder, saving energy. At the same time, the unidirectional and reverse flow of hot air can also discharge the moisture from stewing and baking from the feed pipe, avoiding the moisture outlet and the discharge outlet being at the same place, preventing the coconut shell particles from being re-humidified after stewing and baking.

[0011] A further technical solution is that a plurality of lifting plates are provided at equal angles on the inner wall of the cylinder.

[0012] When using the above solution, the lifting plate is provided to enhance the tumbling effect of the coconut shell particles, thereby improving the drying consistency and shortening the drying time.

[0013] A further technical solution is that the bent pipe includes two upper and lower straight pipes that are obliquely connected, and the two straight pipes together form a 'V'-shaped bent pipe structure. The bent pipe also includes two horizontally arranged cross pipes, and the two cross pipes are respectively connected to the two pipe openings of the bent pipe. The bent pipe is connected to the connecting pipe through the cross pipe, and the air inlet pipe is arranged in the straight pipe that passes through the bent pipe and is arranged above it.

[0014] When the above solution is used, the 'V'-shaped curved pipe structure is more conducive to the transfer of coconut shell particles from top to bottom, and the horizontal pipe is also convenient for connecting the curved pipe with the connecting pipe.

[0015] A further technical solution is that a feed hopper is also provided on the top of the feed pipe.

[0016] When using the above solution, a feeding hopper is provided to increase feeding convenience.

[0017] A further technical solution is that a bottom support frame is also provided at the bottom of the lowest mounting plate.

[0018] When the above solution is used, the height of the lowest installation plate is increased by setting a bottom support frame, so that the discharge hopper is away from the ground, providing convenience for discharging.

[0019] A further technical solution is that the hot air supply mechanism is a hot air blower.

[0020] A further technical solution is that the rotating overhead component includes at least two groups of roller seats arranged at intervals, each group of roller seats includes two roller seats symmetrically arranged on both sides of the cylinder, rollers are rotatably mounted on the roller seats, and the rollers are rollingly connected to the outer wall of the cylinder.

[0021] A further technical solution is that the rotation drive mechanism includes a gear ring fixedly sleeved outside the cylinder, and the rotation drive mechanism also includes a driving component fixedly mounted on the mounting plate, and the driving component is drivingly connected to the gear ring.

[0022] A further technical solution is that the drive assembly includes a gear seat fixed on the mounting plate, a gear is rotatably mounted in the gear seat, the gear is meshed with the gear ring, and the drive assembly also includes a drive motor fixed on the mounting plate, and the drive motor is drivingly connected to the gear.

[0023] The beneficial effects of the utility model are:

[0024] 1. Continuous processing capacity: This solution increases the length of the cylinder within a limited space through the design of continuous rotation of the cylinder and the transportation method of the hollow spiral blades. Through the design of the cylinder distributed up and down and the "wave-shaped" connection method, the solution provides sufficient drying time, realizes the continuous feeding and discharging of coconut shell particles, improves the processing efficiency, and can realize large-scale, automated coconut shell particle drying functions.

[0025] 2. Uniform and efficient drying effect: The coordinated design of the hot air supply mechanism and the spiral blades enables the coconut shell particles to roll and move in the cylinder, effectively avoiding particle accumulation and increasing the heating area of ​​the particles. Each coconut shell particle can get sufficient hot air contact time. Combined with the lifting plate, the rolling effect of the coconut shell particles during the drying process is improved, further improving the consistency and efficiency of drying.

[0026] 3. Energy saving: In addition, the hot air from the bottom layer can be recycled to heat the coconut shell particles on the upper layer, achieving effective energy saving.

[0027] 4. Effective moisture discharge: The one-way and reverse hot air flow design in the scheme ensures that the moisture produced by stewing and baking can be discharged from the feed pipe in time, avoiding the re-humidification of the coconut shell particles after stewing and baking, thereby ensuring product quality.

[0028] 5. Advantages of the 'V'-shaped elbow design: The 'V'-shaped elbow design is conducive to the smooth transfer of coconut shell particles. At the same time, the setting of the horizontal pipe also facilitates the connection between the elbow and the connecting pipe, further improving the practicality and convenience of the equipment.
