Description

Technical Field

[0001] The utility model relates to the technical field of boiling dryers, in particular to a novel boiling dryer. Background Art

[0002] The boiling dryer uses air heated by a heat exchanger to form hot air which is distributed into the main machine through a valve plate. The wet material enters the dryer from the feeder. Due to the effect of wind pressure, the material forms a boiling state in the dryer and comes into extensive contact with the hot air, thus completing the drying of the material in a shorter time.

[0003] For example, a fluidized bed dryer in the prior art, publication number: CN219103484U, is provided with a convenient sampling device on the cylinder wall of the fluidized bed dryer. When the staff needs to observe whether the items inside the dryer have been dried, they only need to push the push rod into the sampling hole so that the sample slot of the sampling tube extends into the dryer, and the items inside the dryer can be sampled. When the items enter the sample slot, the push rod is pulled back to move the sample slot of the sampling tube to the bottom of the discharge port, and then the sampling tube is rotated to take out the items, so as to detect whether they have been completely dried. If they do not meet the drying standards, the items can be put back into the sample slot through the feed port and then put into the fluidized bed dryer, thereby avoiding waste of samples.

[0004] However, during the sampling process, when the sample tank is extended into the dryer, the inside and outside of the dryer are connected, so dust, water vapor or other impurities from the outside will enter the dryer, thereby affecting the cleanliness of the material inside the dryer.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, the novel fluidized bed dryer comprises a raw material barrel 1 on the fluidized bed dryer, an upper motor 8 is fixedly connected to the barrel top of the raw material barrel 1, an upper screw rod 4 is fixedly connected to the output shaft of the upper motor 8, a hollow cover 5 for collecting raw material samples and rising and falling along the depth direction of the raw material barrel 1 is threadedly connected to the upper screw rod 4, a crushing ring 12 for crushing the raw material samples is slidably connected in the hollow cover 5, and a humidity detector 15 for detecting the humidity of the raw material is arranged in the hollow cover 5, the hollow cover 5 is arranged in a ring shape, and a screw cover 6 sleeved on the upper screw rod 4 is spirally installed at the cover opening position at the bottom of the hollow cover 5.

[0024] Specifically, when the humidity of the raw material being dried in the raw material barrel 1 is detected, the upper motor 8 drives the upper screw 4 to rotate, and after the hollow cover 5 is lowered to a certain height, part of the raw material in the raw material barrel 1 in a boiling state will enter the hollow cover 5 along the hollow part of the hollow cover 5, and then the hollow cover 5 will rise and reset along with the upper screw 4, and then the crushing ring 12 will descend to crush the raw material sample in the hollow cover 5, and the humidity of the crushed raw material sample will be detected by the humidity detector 15, so as to judge the degree of drying. As shown in the figure, the feed port of the raw material barrel 1 is arranged near the top of the barrel 1, so that after the drying is completed, it is convenient to rotate and open the screw cover 6 through the feed port, so as to realize the removal of the crushed raw material sample in the hollow cover 5;

[0025] Therefore, in this solution, when detecting the dryness of the raw material sample, the sampling, crushing and testing processes are all carried out in the raw material barrel 1, ensuring that the raw materials in the raw material barrel 1 will not come into contact with the outside air, thereby ensuring the quality of the raw materials.

[0026] In addition, one side of the outer wall of the hollow cover 5 extends outward and is inserted into the inner wall of the raw material barrel 1 , and the top of the outer cover of the hollow cover 5 is fixedly connected with an electric push rod 2 and a plurality of electric telescopic rods 7 .

[0027] The telescopic ends of several electric telescopic rods 7 penetrate the top of the hollow cover 5 and are fixedly connected to the surface of the crushing ring 12. The telescopic ends of the electric push rods 2 penetrate the hollow cover 5 and the surface of the crushing ring 12 and are used to install the humidity detector 15.

[0028] Specifically: In the present solution, the crushing ring 12 is lifted and lowered to crush the raw material sample entering the hollow cover 5 by extending and retracting the electric telescopic rod 7, and the humidity detector 15 is lifted and lowered by extending and retracting the electric push rod 2, so it is convenient to adjust the height of the humidity detector 15. When the dryness is unqualified in the first sampling test, it is convenient to perform a secondary sampling of the raw material sample in the hollow cover 5, and crush it on the crushed sample of the first sampling. By adjusting the position of the humidity detector 15, the humidity of the raw material sample after the secondary sampling and crushing can be detected, so it is convenient to perform multiple sampling of the raw material sample in the raw material barrel 1.

[0029] In addition, a main valve plate 9 and several auxiliary valve plates 10 for injecting hot air are also arranged in the raw material barrel 1. The several auxiliary valve plates 10 are plugged into the main valve plate 9, and the bottom surfaces of the several auxiliary valve plates 10 are fixedly connected with a lifting frame 11 plugged into the main valve plate 9.

[0030] The upper surface of the main valve plate 9 is rotatably connected to the bottom end of the upper screw rod 4 , and the main valve plate 9 is connected to an air pipe 3 which is sleeved on the lifting frame 11 and extends to the outside of the raw material barrel 1 .

[0031] A lower motor 14 is fixedly connected to the bottom of the raw material barrel 1 , and a lower screw rod 13 which is threadedly penetrated through the lifting frame 11 and is rotatably connected to the bottom surface of the main valve plate 9 is fixedly connected to the output shaft of the lower motor 14 .

[0032] Several auxiliary valve plates 10 are also connected with air pipes 3 which are connected to the outside of the raw material barrel 1 in the same direction, and the air pipes 3 on the auxiliary valve plates 10 are flexible pipes.

[0033] Specifically: the main valve plate 9 and the auxiliary valve plate 10 are both provided with hot air through the air pipe 3, and the raw materials in the raw material barrel 1 are dried by the blown hot air, and in the early stage of air-drying, in order to prevent the raw materials from being too heavy due to the humidity inside the raw materials and the introduced hot air from being unable to blow up the raw materials, the lower motor 14 drives the lower screw rod 13 to rotate, and then the lifting frame 11 threadedly connected to the lower screw rod 13 drives the auxiliary valve plate 10 to rise and fall when connected to the main valve plate 9, and then the auxiliary valve plate 10 is lifted and lowered, and the raw materials in the raw material barrel 1 are air-dried from shallow to deep through the lifting of the auxiliary valve plate 10, thereby ensuring the air-drying efficiency.

[0034] Working principle: pour the raw material into the raw material barrel 1 through the feed port. In the early stage of drying, the lower motor 14 drives the lower screw 13 to rotate back and forth, driving the auxiliary valve plate 10 to rise and fall, and air-drying the raw material in the raw material barrel 1 from shallow to deep. During the air-drying process, the upper motor 8 drives the upper screw 4 to rotate, so that the hollow cover 5 descends, and part of the raw material in the raw material barrel 1 enters the hollow cover 5 along the hollow part of the hollow cover 5, and then the electric telescopic rod 7 pushes the crushing ring 12 to descend to crush the raw material sample in the hollow cover 5, and the humidity of the crushed raw material sample is detected by the humidity detector 15 to judge the degree of drying.

The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric push rod 2, the electric telescopic rod 7, the upper motor 8, the lower motor 14 and the humidity detector 15 are no longer explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
