Description

Technical Field

[0001] The utility model relates to the technical field of drying and boiling machines, in particular to a drying and boiling machine with a built-in temperature sensor. Background Art

[0002] Fluidized bed dryer is a drying equipment, also known as fluidized bed, generally composed of heater, fluidized bed host, cyclone separator, bag dust collector, induced draft fan, operating table. Fluidized bed dryer uses air heated by heat exchanger to form hot air which is distributed into the host through valve plate. Wet material enters the dryer from feeder. Due to the effect of wind pressure, the material forms boiling state in the dryer and is in extensive contact with hot air, thus completing material drying in a shorter time.

[0003] During the actual operation of the fluidized bed dryer, since a stirring assembly is provided inside the dryer, it is not convenient to install a temperature sensor. Therefore, the temperature of the incoming hot air and the exhaust hot air is generally monitored. The approximate temperature of the material inside the dryer can be calculated by the temperature difference between the exhaust hot air temperature and the incoming hot air temperature. However, the temperature of the material is not accurate. In the pharmaceutical production process, changes in material temperature have a great influence on the efficacy of the drug. Therefore, it is very important to accurately grasp the material temperature. Based on this, a dry fluidized bed dryer with a built-in temperature sensor is provided. Utility Model Content

[0028] 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.

[0029] See also Figures 1 to 5 In an embodiment of the utility model, a dry boiling machine with a built-in temperature sensor comprises a dry boiling machine 1 composed of a lower cylinder 101, a hopper 102, and an upper cylinder 103. The lower cylinder 101, the hopper 102, and the upper cylinder 103 are sequentially connected from bottom to top. A stirring assembly 2 having a fixed rod 201 is provided on the inner side of the hopper 102. The stirring assembly 2 is used to stir and break up the material inside the hopper 102. One end of the fixed rod 201 penetrates through the outside of the hopper 102 and is fixedly connected with a threaded cylinder 204. An installation cavity 205 is provided at one end of the fixed rod 201 connected to the threaded cylinder 204. A temperature measuring notch 206 is provided on the outer side of the fixed rod 201 located inside the hopper 102. The temperature measuring notch 206 is connected with the installation cavity 205.

[0030] The temperature sensor 3 is installed inside the threaded cylinder 204 and the installation cavity 205. The temperature sensor 3 is used to monitor the temperature of the material inside the hopper 102.

[0031] The temperature sensor 3 includes a connector 301, a threaded protrusion 302, and a temperature probe 303;

[0032] The temperature probe 303 is fixed to one end of the connector 301 and extends to the inner side of the installation cavity 205. The material inside the hopper 102 contacts the temperature probe 303 through the temperature measuring notch 206, so that the temperature probe 303 can detect the temperature of the material.

[0033] The threaded protrusion 302 is integrally formed on the outer side of the connector 301 close to one end of the connector 301, and the threaded protrusion 302 is threadedly connected with the threaded cylinder 204;

[0034] The inner side of the installation cavity 205 is also provided with a plugging component 4 extending to the outer side of the fixing rod 201. When the temperature sensor 3 is disassembled, the temperature measuring slot 206 is blocked by the plugging component 4 to prevent materials from entering the inner cavity of the installation cavity 205.

[0035] The stirring assembly 2 also includes a driving motor 202 and a stirring blade 203;

[0036] A plurality of fixed rods 201 are provided, and the plurality of fixed rods 201 are evenly distributed in a ring shape and fixed to the inner side of the hopper 102 . The driving motor 202 is fixed in the middle of the plurality of fixed rods 201 , and the stirring blade 203 is fixedly connected to the output end of the driving motor 202 .

[0037] In this embodiment: it should be supplemented that: a plurality of ventilation holes are formed at the bottom of the hopper 102, the lower cylinder 101 is connected to the external heat exchanger, and the normal temperature air is heated by the heat exchanger and enters the lower cylinder 101, and then blows the material inside the hopper 102 through the ventilation holes, so that the material is boiled and heated, and an efficient drying effect is achieved. A filter component is arranged inside the upper cylinder 103, and the hot air generated by the heating is filtered through the upper cylinder 103 and then discharged;

[0038] While hot air drying is being performed, the driving motor 202 is synchronously operated to drive the stirring blade 203 to rotate, thereby breaking up the material and preventing the material from agglomerating and affecting the drying effect;

[0039] During the above operation, the boiling material can contact the temperature probe 303 through the through hole 402 and the temperature measuring notch 206, and the temperature probe 303 can detect the temperature of the material. The connector 301 is connected to the external controller through a wire, and the data detected by the temperature probe 303 can be transmitted to the external controller in real time, and displayed on the display screen after being processed by the external controller, so that the staff can easily observe the material temperature;

[0040] By installing a temperature sensor 3 inside the fixed rod 201, accurate temperature detection of the material is achieved without affecting the stirring operation of the material. In addition, by setting up multiple temperature sensors 3, all-round temperature detection inside the hopper 102 can be achieved. Then, by comparing the detection values ​​of multiple temperature sensors 3, the accuracy of material temperature detection can be further improved.

[0041] Please refer to Figures 2 to 5 The sealing assembly 4 includes an outer sleeve 401, a through opening 402, a cross slide 403, a return spring 404, an arc-shaped connecting block 405 and an annular pressing piece 406;

[0042] The outer sleeve 401 is sleeved on the outside of the fixing rod 201 and is located on the inside of the hopper 102. The through hole 402 is opened on the outside of the outer sleeve 401 and corresponds to the position of the temperature measuring notch 206. When the through hole 402 is aligned with the temperature measuring notch 206, the material can contact the temperature probe 303. When the through hole 402 and the temperature measuring notch 206 are horizontally misaligned, the temperature measuring notch 206 is blocked.

[0043] The cross slide 403 is slidably connected to the inner side of the installation cavity 205. A limit slot 207 is provided on the outer wall where the fixing rod 201 contacts the cross slide 403. The cross slide 403 passes through the limit slot 207 and is fixedly connected to the inner wall of the outer sleeve 401.

[0044] The return spring 404 is distributed at one end of the cross slide 403, and the arc-shaped connecting block 405 is fixed at the other end of the cross slide 403. The end of the arc-shaped connecting block 405 away from the cross slide 403 extends to the inner side of the threaded cylinder 204 and is fixedly connected to the annular pressing plate 406. The threaded protrusion 302 squeezes the annular pressing plate 406 to provide power for the movement of the blocking component 4, and the contracted return spring 404 provides power for the return movement of the cross slide 403.

[0045] There are multiple groups of temperature measuring slots 206, which are evenly distributed along the trajectory of the fixed rod 201, and the multiple temperature measuring slots 206 in each group of temperature measuring slots 206 are distributed in a circle, and the temperature measuring slots 206 in two adjacent groups of temperature measuring slots 206 are staggered along the circumferential direction, and the distribution pattern of the through-holes 402 matches the distribution pattern of the temperature measuring slots 206.

[0046] In this embodiment: when a temperature sensor 3 has a problem, it can be disassembled and replaced. During this process, as the threaded protrusion 302 rotates and moves outward, the squeezing force of the threaded protrusion 302 on the annular pressing plate 406 is reduced. At this time, the elastic force of the reset spring 404 is released to push the cross slide 403 to move, and the cross slide 403 drives the outer sleeve 401 to move. Finally, the through hole 402 on the outer sleeve 401 is misaligned with the temperature measuring notch 206, so that the temperature measuring notch 206 is blocked, so that the material will not enter the installation cavity 205.

[0047] The coordination of the above multiple parts enables the temperature sensor 3 to be disassembled and assembled without stopping the machine, which is convenient for maintenance and repair;

[0048] It should be further explained that the provision of multiple groups of temperature measuring notches 206 allows the material to have more comprehensive contact with the temperature probe 303 .

[0049] Please refer to Figures 3 to 5 There are multiple arc-shaped connecting blocks 405 , which are distributed in a ring shape, and the arc-shaped connecting blocks 405 and the temperature measuring slots 206 are staggered, and the inner diameters of the multiple arc-shaped connecting blocks 405 match the outer diameter of the temperature probe 303 .

[0050] In this embodiment, this structure ensures that the arc-shaped connecting block 405 will not block the temperature measuring slot 206 and will not affect the installation of the temperature probe 303 .

[0051] Please refer to Figures 3 to 5 The length of the limiting slide groove 207 is greater than the length of the temperature measuring notch 206 , and the distance between the end surface of the outer sleeve 401 close to one end of the cross slide 403 and the cross slide 403 is greater than the length of the limiting slide groove 207 .

[0052] In this embodiment: through this structure, the movement distance of the outer sleeve 401 can achieve complete blocking of the temperature measuring slot 206, and the outer sleeve 401 always keeps covering the limiting chute 207 to prevent materials from entering the installation cavity 205 through the limiting chute 207.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
