Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate processing, in particular to a drying device. Background Art

[0002] Drying device refers to a device used to remove excess moisture from materials. Drying devices are widely used in many fields such as food, medicine, chemical industry, building materials, metallurgy, etc. to ensure the quality and stability of raw materials or finished products.

[0003] For example, a Chinese utility model patent (CN218821520U) discloses a novel calcium carbonate drying device, which records: "It solves the problem that the existing drying device cannot handle agglomerated calcium carbonate, resulting in poor final drying effect, and is suitable for calcium carbonate drying." It also records: "Since the material itself is moist, a portion of the calcium carbonate will condense into blocks, and these lumps of calcium carbonate will go straight to the discharge port under the action of their own gravity after falling from the conveyor belt. The wind force of the hot air blower cannot blow them to the guide plate for heating and drying. Even if the hot air blower changes the falling path of the lumpy calcium carbonate, it can only make it slide down quickly along the guide plate. In this process, the heating plate has no time to dry it." Technical problems.

[0004] In summary, it can be seen that in the prior art, a crushing roller is used to break up the agglomerated calcium carbonate for subsequent drying. However, this method has the following technical problems: However, in actual use, wet calcium carbonate has a certain viscosity, and the agglomerated part may stick to the surface of the roller, thereby increasing the resistance to the rotation of the roller and increasing the energy consumption required for the use of the device. For this reason, the present application proposes a drying device to solve the technical problems mentioned in the above patents and provide a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide a drying device to address the above technical problems. By rotating the threaded rod, the cleaning plate can be moved close to or away from the extrusion roller under the restriction of the fixed shell and the fixed rod. When the cleaning plate is close to the surface of the extrusion roller, the calcium carbonate attached to the surface of the extrusion roller can be scraped off as the extrusion roller rotates, so as to avoid the agglomerated calcium carbonate sticking to the extrusion roller, which increases the energy required for the rotation of the extrusion roller and reduces the use cost of the device. At the same time, when there is no need to clean the surface of the extrusion roller, the cleaning plate can be adjusted to leave the extrusion roller to avoid the cleaning plate being closely attached to the surface of the extrusion roller, which increases the resistance when the extrusion roller rotates, thereby reducing the energy consumed in the use of the device and improving the practicability of the device.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A drying device is applied to a calcium carbonate drying device.

[0008] The drying device specifically comprises:

[0010] The pulverizing mechanism comprises a rotating shaft, a squeezing roller, a driving assembly, and a cleaning assembly. The inner wall of the device housing is rotatably connected to two rotating shafts, and the outer walls of the two rotating shafts are fixedly connected to squeezing rollers inside the device housing.

The inner wall of the device shell is fixedly connected to the support frame, and the inner wall of the device shell is rotatably connected to the rotating door.

[0014] As a preferred embodiment of the drying device provided by the utility model, the vibration assembly includes a spring fixedly connected to the top of the support frame, the top of the spring is fixedly connected to a sliding frame, the sliding frame is slidably connected to the inner wall of the device shell, the top of the sliding frame is fixedly connected to a vertical plate, and the outer wall of one of the extrusion rollers is fixedly connected to a fixed plate adapted to the vertical plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The drying device provided by the utility model can make the cleaning plate approach or move away from the squeezing roller under the restriction of the fixed shell and the fixed rod by rotating the threaded rod. When the cleaning plate approaches the surface of the squeezing roller, the calcium carbonate attached to the surface of the squeezing roller can be scraped off as the squeezing roller rotates, so as to avoid the agglomerated calcium carbonate from adhering to the squeezing roller, which increases the energy required for the rotation of the squeezing roller, thereby reducing the use cost of the device. At the same time, when it is not necessary to clean the surface of the squeezing roller, the cleaning plate can be adjusted to leave the squeezing roller, so as to avoid the cleaning plate from being closely attached to the surface of the squeezing roller, which increases the resistance when the squeezing roller rotates, thereby reducing the energy consumed by the use of the device and improving the practicability of the device.

When falling on the top of the receiving plate, as the squeezing roller rotates, the sliding frame can vibrate with the assistance of the spring through the fixed plate and the vertical plate, so that the calcium carbonate can be dried continuously for a certain time, and as the calcium carbonate vibrates on the receiving plate, the situation of poor drying effect due to shielding between the calcium carbonate can be avoided, and the calcium carbonate can be dried continuously for a certain time, avoiding the situation of needing to perform secondary drying, thereby avoiding a series of steps such as needing to re-feed the calcium carbonate, and improving the final drying effect and the overall drying rate of the calcium carbonate.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background art, in actual use, wet calcium carbonate has a certain viscosity, and the agglomerated parts may stick to the surface of the roller, thereby increasing the resistance to the rotation of the roller and increasing the energy consumption required for the use of the device.

[0029] In order to solve this technical problem, the utility model provides a drying device, which is applied to a calcium carbonate drying device.

[0030] Specifically, please refer to Figure 1-Figure 2 , the drying device specifically includes:

[0031] The device shell 1 is provided with a crushing mechanism 2, a receiving mechanism 3 is provided inside the device shell 1 and below the crushing mechanism 2, a hot air blower 4 is fixedly installed on the outer wall of the device shell 1, and a collecting box 5 is movably connected to the bottom of the inner wall of the device shell 1;

[0032] The crushing mechanism 2 includes a rotating shaft 6, a squeezing roller 7, a driving assembly, and a cleaning assembly. The inner wall of the device housing 1 is rotatably connected to two rotating shafts 6, and the outer walls of the two rotating shafts 6 and located inside the device housing 1 are fixedly connected to squeezing rollers 7 respectively.

[0033] The drying device provided by the utility model can make the cleaning plate 12 approach or move away from the squeezing roller 7 under the restriction of the fixed shell 11 and the fixed rod 14 by rotating the threaded rod 13. When the cleaning plate 12 approaches the surface of the squeezing roller 7, the calcium carbonate attached to the surface of the squeezing roller 7 can be scraped off as the squeezing roller 7 rotates, so as to avoid the agglomerated calcium carbonate from adhering to the squeezing roller 7, which increases the energy required for the rotation of the squeezing roller 7, thereby reducing the use cost of the device. At the same time, when it is not necessary to clean the surface of the squeezing roller 7, the cleaning plate 12 can be adjusted to leave the squeezing roller 7, so as to avoid the cleaning plate 12 from being closely attached to the surface of the squeezing roller 7, which increases the resistance when the squeezing roller 7 rotates, thereby reducing the energy consumed by the use of the device and improving the practicability of the device. The two squeezing rollers 7 crush the agglomerated calcium carbonate, increase the contact area between the calcium carbonate and the air, and thereby improve the drying efficiency of the calcium carbonate.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 2-Figure 4 , a drying device, comprising:

[0037] The driving assembly includes a gear 8. The outer walls of the two rotating shafts 6 are fixedly connected with gears 8 outside the device housing 1. The two gears 8 have the same size, so that the two rotating shafts 6 rotate at the same speed, thereby ensuring the synchronous rotation of the two extrusion rollers 7 and improving the stability of the device. The two gears 8 are meshed with each other, and the outer wall of the device housing 1 is fixedly connected with a fixing seat 9. The outer wall of the fixing seat 9 is fixedly connected with a driving motor 10. One end of a rotating shaft 6 located outside the device housing 1 is fixedly connected to the output end of the driving motor 10.

[0038] The cleaning assembly includes a fixed shell 11 which is fixedly connected to the inner walls on both sides of the device shell 1 respectively. The inner wall of the fixed shell 11 is slidably connected with a cleaning plate 12 adapted to the squeezing roller 7. The cleaning plate 12 can scrape and clean the outer wall of the squeezing roller 7, thereby ensuring the cleanliness of the outer wall of the squeezing roller 7. The inner wall of the fixed shell 11 is rotatably connected with a threaded rod 13, and the threaded rod 13 is threadedly connected to the inner wall of the cleaning plate 12. The inner wall of the fixed shell 11 is fixedly connected with a fixed rod 14, and the cleaning plate 12 is slidably connected to the outer wall of the fixed rod 14.

[0039] Through the above structural design, the driving motor 10 is started, thereby driving a rotating shaft 6 connected thereto to rotate, and then through the mutual engagement between the two gears 8, the two rotating shafts 6 rotate at the same speed at the same time, thereby driving the two squeezing rollers 7 to rotate accordingly, and the calcium carbonate to be dried is put into the top opening of the device shell 1, and when the calcium carbonate passes between the two squeezing rollers 7, it is crushed by the two squeezing rollers 7 and then falls to the bottom. After the crushing of the calcium carbonate is completed, the corresponding threaded rod 13 is rotated to a suitable degree according to the situation of the calcium carbonate adhered to the outer wall of the squeezing roller 7. The rotating threaded rod 13 drives the cleaning plate 12 to move accordingly under the restriction of the fixed shell 11 and the fixed rod 14, and then when the cleaning plate 12 is close to the outer wall of the squeezing roller 7, the outer wall of the squeezing roller 7 is cleaned as the squeezing roller 7 rotates.

[0040] Embodiment 2:

[0041] The drying device provided in Example 1 is further optimized, specifically, as follows Figure 4-Figure 5 As shown, the receiving mechanism 3 includes a support frame 15, a revolving door 20, a vibration component, and a material discharge component. The inner wall of the device housing 1 is fixedly connected to the support frame 15, and the inner wall of the device housing 1 is rotatably connected to the revolving door 20. The revolving door 20 is provided with a control component to ensure that the revolving door 20 is stably closed.

[0042] The vibration assembly includes a spring 16 fixedly connected to the top of the support frame 15, a sliding frame 17 fixedly connected to the top of the spring 16, the sliding frame 17 is slidably connected to the inner wall of the device housing 1, a vertical plate 21 is fixedly connected to the top of the sliding frame 17, and a fixed plate 22 adapted to the vertical plate 21 is fixedly connected to the outer wall of an extrusion roller 7, and corresponding inclined surfaces are provided on the vertical plate 21 and the fixed plate 22, and the rotating fixed plate 22 will squeeze the vertical plate 21 and cause the vertical plate 21 to drop.

[0043] The material unloading assembly includes a receiving plate 18 slidably connected to the inner wall of the sliding frame 17, and a material blocking plate 19 is fixedly connected to the top of the sliding frame 17. The material blocking plate 19 prevents calcium carbonate from flowing out over the sliding frame 17 due to the movement of the receiving plate 18, thereby ensuring the stability of the device.

[0044] Through the above-mentioned structural design, after the calcium carbonate is crushed, it is dried by hot air during the falling process, and then falls to the top of the receiving plate 18 to be received, and then with the rotation of the squeezing roller 7, the fixed plate 22 can be driven to move accordingly, and then the vertical plate 21 is squeezed. During this process, the sliding frame 17 slides downward along the inner wall of the device housing 1, and the spring 16 is compressed accordingly. With the movement of the fixed plate 22, when the fixed plate 22 is separated from the vertical plate 21, the spring 16 releases the elastic force, driving the sliding frame 17 to vibrate, thereby causing the calcium carbonate on the receiving plate 18 to move accordingly. After being dried to a certain extent by the hot air continuously blown out by the hot air blower 4, the rotating door 20 is opened, and then the receiving plate 18 is pulled out, so that the calcium carbonate on the receiving plate 18 falls into the collection box 5 and is collected under the obstruction of the baffle plate 19.
