Description

Technical Field

[0001] The utility model relates to the technical field of fish meal feed processing, in particular to a drum type fish meal dryer. Background Art

[0002] Fishmeal feed is mainly made of various fish as raw materials, and other biological tissues are added. Fishmeal does not contain fiber and other difficult-to-digest substances, but has high crude fat content and high effective energy value. It is easy to make high-energy feed with fishmeal as raw material in production. At the same time, fishmeal is rich in B vitamins, including high content of vitamin B2 and B12, and also contains fat-soluble vitamins such as vitamin A, D and VE, which can stimulate the growth and development of animals. With the continuous expansion of my country's aquaculture industry and the rapid growth of aquatic feed, the demand for fishmeal has also entered a stage of sustained high growth.

[0003] In the current fish meal production process, the dried fish meal raw materials are ground and milled to obtain fish meal, and the crushed and milled fish meal will precipitate some water, which requires the fish meal to be dried to improve the shelf life of the fish meal. The drying process of the existing fish meal dryer is: stop - add fish meal - stir and dry - stop - discharge. In this process, the machine needs to be stopped every time the material is loaded and discharged, resulting in low drying efficiency of the fish meal.

[0004] In view of this, a drum-type fish meal dryer is designed to provide continuous feeding and discharging functions while maintaining drying operations, and to solve the problem of poor control of drying time caused by the mixing of new and old fish meal during continuous feeding and discharging, and to solve the problem of fish meal dust leakage during continuous feeding and discharging. Utility Model Content

[0005] The utility model aims to provide a drum type fish meal dryer, so as to effectively improve the drying efficiency of the fish meal and solve the problems described in the background technology.

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

[0007] A drum-type fish meal dryer comprises a first support seat and a second support seat fixedly mounted on a bottom plate, an olive-shaped drum is arranged between the first support seat and the second support seat, the drum comprises a cylinder and a feed cone and a discharge cone respectively connected to the two ends of the cylinder, a feed shaft tube is arranged at the end of the feed cone, a discharge shaft tube is arranged at the end of the discharge cone, the feed shaft tube is rotatably installed in the first support seat, the discharge shaft tube is rotatably installed in the second support seat, at least two stirring plates are arranged on the inner wall of the cylinder, a spiral blade is arranged on the inner wall of the discharge cone, the center line of the spiral blade is hollow, a first bracket is also arranged on the bottom plate, and the first bracket is also provided with a A feed inclined pipe is provided, a one-way feeding mechanism is provided on the top of the feed inclined pipe, an air inlet pipe is connected to the upper middle part of the feed inclined pipe, a feed cross pipe is connected to the bottom of the feed inclined pipe, the outer wall of the feed cross pipe is rotatably sealed with the inner wall of the feed shaft pipe, a hot air blower is also provided on the bottom plate, the air outlet of the hot air blower is also connected to the air inlet pipe through the air outlet pipe, a driving mechanism for driving the drum to rotate is also provided on the bottom plate, a second bracket is also provided on the bottom plate, a storage tank is also provided on the second bracket, the discharge shaft pipe rotating shaft seal is penetrated in the side wall of the storage tank, a discharge pipe is provided at the bottom of the storage tank, a discharge valve is provided in the discharge pipe, and a filtering air outlet mechanism is provided on the top of the storage tank.

[0008] When using the above scheme, start the hot air blower, and the dry hot air enters the air inlet pipe along the air outlet pipe, and then sprays downward into the feed inclined tube through the air inlet pipe. Then, the fish meal is put into the one-way feeding mechanism at the top of the feed inclined tube. Under the action of gravity, the fish meal slides along the feed inclined tube to the feed transverse tube. Since the air inlet pipe is arranged above the feed inclined tube, the fish meal sliding downward will not enter the air inlet pipe, and the dry hot air is sprayed into the feed inclined tube from the air inlet pipe to form a downward airflow, which can form an inhalation airflow at the upper end entrance of the feed inclined tube, and the dust generated when the fish meal is fed is sucked into the feed inclined tube. Under the action of inertia, the fish meal rushes out of the feed transverse tube and enters the feed cone. The fish meal remaining at the feed transverse tube at the end of feeding will also be continuously washed by the dry hot airflow and enter the drum, avoiding fish meal residue. The one-way feeding mechanism can also prevent the accidental leakage of fish meal dust when feeding is suspended.

[0009] After the fish meal enters the drum, it slides along the feed cone to the cylinder. Under the action of the driving mechanism, the drum rotates, and the stirring plate continuously drives the fish meal deposited at the bottom of the cylinder to the mid-air and then falls down, realizing the tumbling function of the fish meal. The dry hot air continuously contacts the fish meal in the drum to quickly dry the fish meal.

[0010] As the amount of fish meal added increases, the fish meal gradually covers and moves toward the discharge cone. When the fish meal moves to the discharge cone, the dried fish meal, driven by the spiral blades, continuously moves toward the gradually shrinking end outlet of the discharge cone until it enters the discharge shaft tube and is discharged. The continuously discharged fish meal releases the volume inside the drum, thereby realizing the continuous feeding function. At the same time, the fish meal moves linearly in the drum, avoiding the situation where the new fish meal is not fully dried and is discharged with the old fish meal. By extending the length of the cylinder, the fish meal can get enough drying time during the continuous linear movement.

[0011] The fish meal falls from the discharge shaft into the storage tank and gradually accumulates at the bottom of the storage tank. When the discharge valve at the bottom of the storage tank is opened, the accumulation of fish meal blocks the fish meal. Therefore, when the fish meal is discharged from the discharge pipe, no dry hot air flow will carry fish meal dust out.

[0012] The increasing air pressure in the drum is released and exhausted from the filter outlet mechanism on the top of the storage tank, while preventing the dust in the storage tank from overflowing.

[0013] The hollow centerline of the spiral blade can provide a quick outlet to the storage tank for the continuously entering dry hot air flow, thus preventing the dry hot air from accumulating in the drum and being unable to be discharged, causing turbulent air flow inside the drum, or even reversely pouring into the feed inclined pipe from the feed horizontal pipe.

[0014] With the help of the above-mentioned components and mechanisms, the fish meal can achieve the function of continuous feeding and discharging while maintaining the drying operation, and solve the problem of poor control of drying time caused by the mixing of new and old fish meal during continuous feeding and discharging, and also solve the problem of fish meal dust leakage during continuous feeding and discharging.

[0015] A further technical solution is that the one-way feeding mechanism includes a straight pipe arranged at the top of the feeding inclined pipe, a check valve is arranged in the straight pipe, and the one-way feeding mechanism also includes a feeding hopper arranged at the top of the straight pipe.

[0016] When the above solution is used, the check valve can realize the one-way feeding function. When the fish meal is fed, the check valve is opened. After the fish meal stops feeding, the check valve is reset to block the straight pipe.

[0017] A further technical solution is that the angle between the central axis of the air intake pipe and the central axis of the feed inclined tube does not exceed the angle between the central axis of the air intake pipe and the central axis of the feed inclined tube when the air intake pipe is vertically arranged.

[0018] When the above solution is used, the air intake pipe is arranged vertically or tends to be arranged parallel to the feed inclined pipe, so that the downward fluidity generated by the dry hot air flow after entering the air intake inclined pipe is stronger.

[0019] A further technical solution is that a first sealing bearing is sleeved on the outer side wall of the feed transverse tube, and the outer side wall of the first sealing bearing is fixedly and sealedly embedded in the inner side wall of the feed shaft tube.

[0020] A further technical solution is that a driven gear ring is fixedly sleeved on the outer wall of the cylinder, and the driving mechanism includes a motor, a reduction box and a gear seat arranged on the base plate, the motor is drivingly connected to the reduction box, and a driving gear is rotatably installed in the gear seat, the reduction box is drivingly connected to the driving gear, and the driving gear is meshed with the driven gear ring.

[0021] When the above solution is used, the motor drives the reduction box, the reduction box drives the driving gear in the gear seat to rotate, the driving gear drives the driven gear ring to rotate, the driven gear ring drives the cylinder to rotate, and the cylinder drives the roller to rotate.

[0022] A further technical solution is that a windshield is provided in the drum space between the stirring plate and the spiral blade. The windshield is provided in the hollow of the center line of the spiral blade to shield the hollow. The windshield is fixedly connected to the side wall of the drum through a connecting rod.

[0023] When the above solution is used, the wind shield prevents excessive air flow between the feed shaft tube and the discharge shaft tube, prevents the fish meal from being raised by the excessive air flow, and prevents a large amount of fish meal dust from being directly discharged into the storage tank from the hollow of the spiral blade.

[0024] A further technical solution is that the inner side wall of the discharge shaft tube is conical, and the inner diameter of the tube opening on one side of the discharge shaft tube close to the drum is smaller than the inner diameter of the tube opening on the other side of the discharge shaft tube.

[0025] When the above solution is used, the conical inner wall of the discharge shaft tube is conducive to the smooth discharge of the fish meal.

[0026] A further technical solution is that a material baffle plate is connected to the pipe opening of the feed transverse pipe toward the drum, and the material baffle plate is inclined toward the bottom plate.

[0027] When the above solution is used, the inclined baffle plate is conducive to the fish meal falling into the feeding cone quickly, so that the fish meal can move linearly in the middle layer of the drum better.

[0028] A further technical solution is that a second sealing bearing is sleeved on the outer side wall of the discharge shaft tube, and the outer side wall of the second sealing bearing is fixedly and sealedly penetrated into the side wall of the storage tank.

[0029] A further technical solution is that the filtering air outlet mechanism includes an exhaust pipe that is sealed and penetrates through the top wall of the storage tank, and a filter layer is provided in the exhaust pipe.

[0030] The beneficial effects of the utility model are:

[0031] 1. By setting a one-way feeding mechanism in conjunction with the feeding inclined tube and the air inlet pipe, the fish meal slides along the feeding inclined tube to the feeding transverse tube under the action of gravity. The fish meal sliding downward will not enter the air inlet pipe arranged above the feeding inclined tube. The dry hot air sprays downward into the feeding inclined tube to form a downward airflow, so that an internal suction airflow is formed at the upper entrance of the feeding inclined tube to inhale the dust generated when the fish meal is fed. With the one-way feeding mechanism, dust overflow is avoided. The fish meal remaining at the feeding transverse tube at the end of feeding will also be continuously washed by the dry hot airflow and enter the drum, avoiding fish meal residue.

[0032] 2. By setting up an olive-shaped drum, with a stirring plate and spiral blades, the fish meal moves linearly in the drum according to the designed movement route. The stirring plate realizes the tumbling function of the fish meal, and the dry hot air continuously contacts the fish meal in the drum to achieve rapid drying of the fish meal. The dried fish meal is discharged under the drive of the spiral blades, releasing the internal volume of the drum, thereby realizing the continuous feeding function. The linear movement of the fish meal in the drum also avoids the situation where the new fish meal is not fully dried and is discharged with the old fish meal. By extending the length of the cylinder, the fish meal can get enough drying time during the continuous linear movement.

[0033] 3. By setting up a storage tank with bottom discharge and top exhaust, fish meal gradually accumulates at the bottom of the storage tank, blocking the dust in the storage tank. Therefore, when the fish meal is discharged from the discharge pipe, no dry hot air will rush out with fish meal dust. At the same time, the increasing air pressure in the drum is released and exhausted from the filter outlet mechanism at the top of the storage tank to prevent the dust in the storage tank from overflowing.

[0034] 4. By setting hollow spiral blades and wind shields, the continuously entering dry hot air flow is given a quick outlet to the storage tank, avoiding the accumulation of dry hot air in the drum and the inability to discharge it, which causes turbulence in the drum air flow, or even reversely pouring into the feed inclined tube from the feed horizontal tube. It can also avoid excessive air flow between the feed shaft tube and the discharge shaft tube, prevent fish meal from being raised by excessive air flow, and prevent a large amount of fish meal dust from being directly discharged into the storage tank from the hollow of the spiral blades.
