Description

Technical Field

[0001] The utility model relates to the field of dryers, in particular to a circulating drying type material dryer. Background Art

[0002] Ammonium perchlorate is an inorganic compound, a white crystalline powder, and is deliquescent. Ammonium perchlorate is a strong oxidant, and will explode when mixed with reducing agents, organic matter, flammable substances such as sulfur, phosphorus, or metal powder. Contact with strong acids may cause combustion and explosion. It is used to make explosives, fireworks, and as an analytical reagent. When drying ammonium perchlorate, you need to pay attention to the drying temperature. Too high a temperature will cause ammonium perchlorate to decompose and produce oxygen, chlorine, nitrogen, and water.

[0003] The patent with publication number CN209763704U provides a material dryer, including a drying cylinder, a drying tower, a feeding device, a discharging transmission belt and a heating device. The drying cylinder is sleeved outside the drying tower and is coaxially arranged. The inner wall of the drying cylinder cooperates with the outer wall of the drying tower to form an annular cavity. However, the above scheme has the following shortcomings: it cannot be cyclically dried. If it is not dried thoroughly, workers need to manually return it to the feed port for re-drying. It is highly dependent on manual labor, resulting in low work efficiency. In addition, the above device is prone to powder flying when in use, posing a threat to the health of workers. In addition, because the material enters the device at one time, it is easy to cause the material in the center to be not dried thoroughly due to material accumulation.

[0004] Therefore, it is necessary to propose a circulating drying material dryer to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a circulating drying material dryer to solve the above-mentioned problems of being unable to perform circulating drying autonomously, being highly dependent on manual labor, and having low drying efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulating drying type material dryer comprises a cylindrical shell, a mounting plate is fixedly installed on one side of the cylindrical shell, a storage shell is fixedly installed on the side of the mounting plate away from the cylindrical shell, a dehumidifier is fixedly installed on the top of the storage shell, a spiral circulation pipe is fixedly installed at the middle position of the lower end of the storage shell, a collection funnel is fixedly installed on the lower end of the storage shell, the collection funnel is connected with the middle part of the spiral circulation pipe, a circulation auger is rotatably installed inside the spiral circulation pipe, an air circulation port is provided at the upper end of the storage shell away from the mounting plate, the air circulation port is located above the collection funnel, a blocking cylinder is fixedly installed inside the air circulation port, an inclined baffle is fixedly installed inside the blocking cylinder, a filter hole is provided in the upper half of the inclined baffle, and the inclined baffle is inclined.

[0007] Preferably, a servo motor is fixedly installed at one end of the spiral circulation duct, and the driving end of the servo motor extends to the interior of the spiral circulation duct and is fixedly installed at the end of the circulation auger. A transition duct is fixedly installed at the upper end position between the mounting plate and the storage shell, and the transition duct is located above the aggregate funnel, and the transition duct is not in a coaxial position with the air circulation port, and the transition duct is connected with the interior of both the cylindrical shell and the storage shell, and the mounting plate is located below the transition duct and is provided with a material circulation port, and one end of the spiral circulation duct away from the servo motor is fixedly installed inside the material circulation port, and the spiral circulation duct is connected with the interior of the cylindrical shell.

If it meets the standard, it will be directly transported out of the device. If it does not meet the standard, the material will be returned to the drying chamber for re-drying, realizing autonomous judgment and cyclic drying, reducing labor requirements and improving the final product quality;

[0014] 2. By setting up a hot air blower, the material inside the cylindrical shell is rotated and lifted up, so that the material particles are fully in contact with the air, increasing the evaporation surface area, thereby increasing the evaporation rate, making the material dry more thoroughly, and there will be no accumulation that causes incomplete drying of the internal material;

[0015] 3. The device is in a sealed state as a whole. After the material is flying inside the cylindrical shell, it settles inside the storage shell, so it will not be blown out of the device, reducing the loss of materials, especially for powders such as ammonium perchlorate that have certain toxicity and oxidizing properties. Closed drying can ensure the safety of processing workers and will not be affected by the humidity of the external environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6The circulating drying material dryer shown includes a cylindrical shell 1, and a mounting plate 11 is fixedly installed on one side of the cylindrical shell 1. The mounting plate 11 can keep the interior of the storage shell 2 sealed to prevent powder from flying. A storage shell 2 is fixedly installed on the side of the mounting plate 11 away from the cylindrical shell 1, and the dried powder will enter the interior of the storage shell 2. A dehumidifier 3 is fixedly installed on the top of the storage shell 2. The dehumidifier 3 is used to remove water vapor in the air circulation process so that the circulating air is always kept dry. A spiral circulation pipe 4 is fixedly installed in the middle position of the lower end of the storage shell 2. The spiral circulation pipe 4 is used to transport the dried material to the outside of the storage shell 2, or return the incompletely dried material to the cylindrical shell 1 for re-drying.

[0025] A transition pipe 12 is fixedly installed at the upper end position between the mounting plate 11 and the storage shell 2. The transition pipe 12 is used to connect the cylindrical shell 1 and the storage shell 2. The transition pipe 12 is connected to the interior of the cylindrical shell 1 and the storage shell 2. The mounting plate 11 is provided with a material circulation port 13 below the transition pipe 12. A spiral feeding device 5 is fixedly installed at the lower end of the cylindrical shell 1 on the side away from the mounting plate 11. When in use, the spiral feeding device 5 continuously works to continuously transport the material into the interior of the cylindrical shell 1, and then after the interior of the cylindrical shell 1 is dried, it is transported to the interior of the storage shell 2 through the transition pipe 12, and then falls into the spiral circulation pipe 4. The spiral circulation pipe 4 returns the undried material to the interior of the cylindrical shell 1 through the material circulation port 13. If it is completely dried, the material will be transported to the outside of the device.

[0026] A collecting funnel 41 is fixedly installed at the lower end of the interior of the storage shell 2. The collecting funnel 41 is connected to the middle part of the spiral circulation pipe 4. The collecting funnel 41 is used to collect materials into the interior of the spiral circulation pipe 4. A circulating auger 44 is rotatably installed inside the spiral circulation pipe 4. A humidity detector 45 is fixedly installed on the upper side of the collecting funnel 41. The transition pipe 12 is located above the collecting funnel 41.

[0027] A servo motor 42 is fixedly installed at one end of the spiral circulation pipe 4, and the servo motor 42 is used to provide rotation for the circulation auger 44. The driving end of the servo motor 42 extends to the interior of the spiral circulation pipe 4 and is fixedly installed at the end of the circulation auger 44. The end of the spiral circulation pipe 4 away from the servo motor 42 is fixedly installed inside the material circulation port 13. The spiral circulation pipe 4 is connected to the interior of the cylindrical shell 1. A discharge port 43 is fixedly installed at the lower side of the spiral circulation pipe 4 close to the servo motor 42. When the servo motor 42 rotates forward, the material inside it will be transported to the discharge port 43 along with the circulation auger 44 and fall from the discharge port 43 to complete the unloading. When the servo motor 42 reverses, the material will be transported back to the interior of the cylindrical shell 1 along with the circulation auger 44 for circulation drying.

[0028] The humidity detector 45 can monitor the humidity of the material falling into the spiral circulation pipeline 4 in real time. If the humidity does not meet the processing requirements, the humidity detector 45 will output a signal to the signal converter, which will be converted into an electrical signal that can be used by the servo motor 42, thereby controlling the forward and reverse rotation of the servo motor 42. The signal converter is not shown in the figure, and the signal converter is a prior art and will not be described again.

[0029] An air circulation port 21 is provided at the upper end of the side of the storage shell 2 away from the mounting plate 11. The air circulation port 21 is located above the aggregate funnel 41, and the transition duct 12 is not coaxial with the air circulation port 21. A blocking cylinder 22 is fixedly installed inside the air circulation port 21, and an inclined baffle 23 is fixedly installed inside the blocking cylinder 22. A filter hole 24 is provided in the upper half of the inclined baffle 23, and the inclined baffle 23 is inclined.

[0030] The input end of the dehumidifier 3 is connected to the air circulation port 21 through a first pipe 31, and a second pipe 32 is fixedly installed at the output end of the dehumidifier 3. The diameter of the transition pipe 12 is smaller than the diameter of the air circulation port 21, and the diameter of the air circulation port 21 is smaller than the diameter of the second pipe 32. A hot air blower 33 is fixedly installed at one end of the second pipe 32 away from the dehumidifier 3, and a blowing pipe 34 is fixedly installed at the output end of the hot air blower 33. A blowing port 14 distributed along the tangential direction is opened on one side of the cylindrical shell 1 close to the blowing pipe 34, and the blowing pipe 34 is fixedly installed inside the blowing port 14.

[0031] During actual use, the hot air blower 33 and the dehumidifier 3 are working, and the dehumidifier 3 blows air into the interior of the cylindrical shell 1 through the blowing duct 34. Because the blowing port 14 is opened along the tangential direction, the air blown by the hot air blower 33 will lift the material inside the cylindrical shell 1, and the cylindrical shell 1 is cylindrical in shape, so the powder material will rotate along the inner wall of the cylindrical shell 1, so that each particle of the powder material is in uniform contact with the hot air, increasing the contact area and temperature, and greatly improving the drying efficiency. When the hot air blower 33 and the dehumidifier 3 are working to blow air, they will also inhale air, so the air inside the cylindrical shell 1 will enter the interior of the storage shell 2 along the transition duct 12, and there is no airflow inside the storage shell 2, so most of the particles will fall on the collecting funnel 41 and be collected by the collecting funnel 41 into the interior of the spiral circulation duct 4, and the air will be sucked into the interior of the dehumidifier 3 through the air circulation port 21 and the first duct 31.

[0032] The inclined baffle 23 is provided so that a small amount of particles moving with the airflow will be filtered by the filter holes 24. Under the continuous blowing of wind, and the inclined baffle 23 is designed to be inclined, the particles will gradually move downward under the action of wind and gravity until the particles move to the lower end of the inclined baffle 23. At this time, because the filter holes 24 are not provided at the lower end of the inclined baffle 23, the particles lose the suction brought by the airflow and are then driven by gravity to fall into the interior of the spiral circulation duct 4.

[0033] The air entering the dehumidifier 3 is warm and humid air. The dehumidifier 3 can filter the water vapor in the air and then deliver it to the hot air blower 33. The hot air blower 33 heats the air and then delivers it to the cylindrical shell 1 to complete the air circulation. It should be noted that the hot air blower 33 has the function of controlling the output air flow temperature.
