Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a novel drum cooler. Background Art

[0002] Drum coolers are widely used in the feed and oil industries, primarily to cool materials subjected to high temperature and high humidity in the upstream process to a temperature suitable for storage and transportation. They operate by rotating the material from front to back within the drum, while cooling air flows from back to front, creating convection with the material. This is a commonly used accessory device.

[0003] Existing drum coolers have the following problems: 1. The feed auger and the drum are driven by the same power, so the speed of the feed and the drum cannot be adjusted independently, the processing capacity of the two cannot be well matched, and the production capacity of the drum will be limited; 2. Natural air can only enter from the rear, and in extremely cold areas, the cooling is too fast and the moisture of the material cannot be effectively removed. Summary of the Invention

[0004] In order to solve the technical problem in the prior art that the feeding part and the drum part of the drum cooler cannot be adjusted independently, the present application proposes a new type of drum cooler to solve the above technical problem.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The utility model provides a new type of drum cooler, comprising: a frame; a feed auger, which is arranged on the frame, and the auger shaft of the feed auger extends out of one end of the shell of the feed auger to form an auger drive end, and the auger drive end is directly driven by a feed drive reducer arranged at the first end of the frame; a roller, which is rotatably arranged on the frame and is in a straight line with the axis of the feed auger, and one end of the roller is formed with a circular groove inserted into one end of the feed auger, and a roller shaft passing through the roller is arranged at the axis of the roller, and the end of the roller shaft away from the feed auger extends out of the roller and forms a roller drive end, and the roller drive end is directly driven by the roller drive reducer arranged at the second end of the frame.

[0007] Furthermore, an independent air inlet channel is configured at one end of the drum away from the feeding auger, one end of the air inlet channel is communicated with the internal space of the drum, and the other end of the air inlet channel is configured with a docking flange.

[0008] Furthermore, a discharge channel is provided at one end of the drum away from the feeding auger, and one end of the discharge channel is connected to the air inlet channel.

[0009] Furthermore, the cylinder body of the drum is inclined so that the material in the cylinder body can flow to the discharge channel in a natural state.

[0010] Furthermore, a wear-resistant elastic sealing material is provided at the joint between the end cover of the roller away from the feed auger and the barrel of the roller. The joint between the end cover of the roller and the barrel is connected by bolts, and a spring is provided on the screw rod of the bolt to tighten the fit between the end cover of the roller and the barrel.

[0011] Furthermore, the shell of the feeding auger is provided with a feeding port and an air suction port with the openings facing upwards.

[0012] Furthermore, a plurality of blades are arranged in the inner space of the drum.

[0013] Furthermore, the feed drive reducer and the drum drive reducer both use variable frequency motors.

[0014] Based on the above technical solution, the technical effects that can be achieved by the present invention are:

[0015] The new drum cooler of the utility model has the material entering the drum through the feed auger, which is directly driven by the feed drive reducer, and the feed amount can be independently controlled. After the material is fed into the drum through the feed auger, the drum is driven to rotate by the drum shaft connected to the drum drive reducer. The drum drive reducer directly and independently controls the drum speed to adapt to materials of different bulk densities, solving the technical problem of the drum cooler in the prior art that the feeding part and the drum part cannot be adjusted independently. At the same time, the feed drive reducer of the new drum cooler of the utility model is directly connected to the auger shaft, and the drum drive reducer is also directly connected to the drum shaft, which makes the drive more direct, the structure more compact, simple, and low-cost.

[0016] The new drum cooler of the utility model is equipped with a separate air inlet channel, which can use natural wind for cooling or connect to an external blower to introduce hot air for drying.

[0017] The new drum cooler of the present invention is connected with the end cover of the drum and the cylinder body at the joint by bolts, and a spring is sleeved on the screw rod of the bolt to tighten the fit between the end cover of the drum and the cylinder body, and the wear-resistant elastic sealing material is configured at the joint of the end cover and the cylinder body of the drum. The spring and the wear-resistant elastic sealing material form a plane seal, which can also play a good sealing role during the rotation of the drum (when the drum cooler is working, since the drum needs to rotate all the time, relative rotation will occur between the drum and the end cover. In order to ensure the sealing between the drum and the end cover and avoid material leakage, wear-resistant elastic sealing material is usually arranged on the end of the drum or the end cover, and then the wear-resistant elastic sealing material is jointly extruded by the drum and the end cover to ensure the sealing between the drum and the end cover), so that the wind coming in from the air inlet channel or the dust in the material will not escape from the side gap.

The drum 3 is rotatably arranged on the frame 1 and is in a straight line with the axis of the feed auger 2. A circular groove is formed at one end of the drum 3 to be inserted into one end of the feed auger 2, and a drum shaft 31 passing through the drum 3 is arranged at the axis of the drum 3. The drum shaft 31 extends out of the drum 3 away from the end of the feed auger 2 and forms the drum 3 drive end, and the drum 3 drive end is directly driven by a drum drive reducer 32 arranged at the second end of the frame 1.

[0024] In the new drum cooler of the present invention, the material enters the drum 3 through the feed auger 2, and the feed auger 2 is directly driven by the feed drive reducer 22 alone, and the size of the feed amount can be independently controlled. After the material is fed into the drum 3 through the feed auger 2, the drum 3 is driven to rotate by the drum shaft 31 connected to the drum drive reducer 32. The drum drive reducer 32 directly and independently controls the rotation speed of the drum 3 to adapt to materials with different bulk densities, solving the technical problem in the prior art that the feeding part and the drum 3 part of the drum 3 cooler cannot be adjusted independently. At the same time, the feed drive reducer 22 of the new drum cooler of the present invention is directly connected to the auger shaft 21, and the drum drive reducer 32 is also directly connected to the drum shaft 31, so the drive is more direct, the structure is more compact and simple, and the cost is low.

[0025] In a preferred embodiment of the present invention, an independent air inlet channel 4 is provided at one end of the drum 3 away from the feed auger 2, one end of the air inlet channel 4 is connected to the internal space of the drum 3, and the other end of the air inlet channel 4 is provided with a docking flange. The independent air inlet channel 4 can utilize natural wind for cooling, and can also be connected to an external blower to introduce hot air for drying operations.

[0026] Furthermore, a discharge channel 5 is provided at one end of the drum 3 away from the feed auger 2 , and one end of the discharge channel 5 is connected to the air inlet channel 4 .

[0027] Furthermore, the cylinder body of the drum 3 is tilted so that the material in the cylinder body can flow to the discharge channel 5 in a natural state.

[0028] In a preferred embodiment of the present invention, a wear-resistant elastic sealing material is provided at the joint between the end cover of the drum 3 at one end away from the feed auger 2 and the barrel of the drum 3. The joint between the end cover of the drum 3 and the barrel is connected by bolts, and a spring 33 is sleeved on the screw of the bolt to tighten the fit between the end cover and the barrel of the drum 3. When the drum 3 type cooler is working, since the drum 3 needs to rotate continuously, relative rotation will occur between the drum 3 and the end cover. In order to ensure the sealing between the drum 3 and the end cover and avoid material leakage, a wear-resistant elastic sealing material is usually provided on the end of the drum 3 or the end cover, and then the wear-resistant elastic sealing material is jointly extruded by the drum 3 and the end cover to ensure the sealing between the drum 3 and the end cover, so as to prevent the wind coming in from the air inlet duct 4 or the dust in the material from escaping from the side gap.

[0029] Specifically, the shell of the feed auger 2 is provided with a feed port 23 and an air suction port 24 that open upward.

[0030] Specifically, a plurality of blades 34 are disposed in the inner space of the drum 3 .

[0032] In the new drum cooler of the present invention, the material enters the material screw dragon through the feed port 23, and the feed screw dragon 2 is driven by the feed drive reducer 22, which is a variable frequency motor and can independently control the size of the feed amount. After the material is fed into the drum 3 through the feed screw dragon 2, the drum 3 is connected to the drum drive reducer 32 by the drum shaft 31 to drive the drum to rotate. The drum drive reducer 32 is also a variable frequency motor and can independently control the speed of the drum 3 to adapt to materials of different bulk densities. Blades 34 are provided in the drum 3 to drive the material to rotate and throw it up. Generally, the drum 3 cooler is installed with a certain inclination. Degree, convenient for the material to flow better to the discharge port of the discharge channel 5, the end of the drum 3 away from the feed auger 2 is provided with a flat sealing structure, which is composed of a spring 33 and a wear-resistant elastic sealing material. It can play a good sealing role even in rotation, so as to prevent the wind coming in from the air inlet channel 4 or the dust in the material from escaping from the side gap. The material flows from the first end to the second end of the frame 1, and the wind enters from the second end to the first end of the frame 1, thereby cooling or drying when hot air is introduced, and then flows into the next process from the discharge channel 5.

[0033] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
