Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a paddle dryer for uniform drying. Background Technology

[0002] As is well known, paddle dryers are commonly used drying equipment in industries such as chemical, pharmaceutical, and food processing. They mainly consist of a jacketed horizontal cylinder, a stirring shaft and paddles, a transmission device, and infeed / discharge devices. During operation, wet material enters through the inlet, where steam, heat transfer oil, or other heat media in the jacket provide heat. The stirring shaft drives the paddles to rotate, agitating and stirring the material to ensure full contact with the hot wall surface for moisture evaporation, and also propelling the material forward. The dried material is then discharged from the outlet. This equipment boasts high drying efficiency, low energy consumption, the ability to process various materials, controllable material residence time, and continuous production capability, making it widely applicable in various production processes requiring drying.

[0003] However, existing paddle dryers have certain drawbacks when drying materials. Typically, materials are directly poured into the machine for drying, but some materials are large in size, resulting in a relatively low specific surface area. Consequently, it is difficult to achieve a uniform state during heat transfer. In addition, the fixed position of the feed inlet causes the material to tend to accumulate in a certain area inside the machine after entering. Even with subsequent stirring by the agitator, it is difficult to achieve effective uniform stirring, ultimately leading to reduced uniformity of material drying and affecting the drying effect and product quality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a paddle dryer that provides uniform drying.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a uniformly drying paddle dryer, comprising a base plate, a machine body, a support base, a sealing plate, and a crushing mechanism. One end of the support base is connected to the top of the base plate, and the other end of the support base is connected to the bottom of the machine body. Several support bases are provided. The top of the machine body has a feed inlet. One end of the sealing plate passes through the feed inlet. An electromagnet is provided on the outer wall of the feed inlet, attracting the sealing plate. A groove is formed on the inner wall of the feed inlet, matching the sealing plate. The crushing mechanism includes a sliding component, a housing, a crushing component, a feeding component, and a discharging component. The housing is connected to the base plate via the sliding component. A feeding component is located at the center of the top of the housing, and a discharging component is located at the center of the bottom of the housing. The bottom part of the discharging component is located inside the feed inlet. Two crushing components are located on the top of the housing. Two sliding components are also provided. A controller is provided on the base plate, electrically connected to the sliding components.

[0008] For ease of operation, the present invention is improved in that the controller is electrically connected to the crushing component and the controller is electrically connected to the machine body.

[0009] To facilitate observation of the interior of the enclosure, this utility model is improved by providing an observation window on one side of the enclosure, which is embedded in the side of the enclosure.

[0010] To improve the strength of the observation window, this utility model is improved by using transparent tempered glass as the observation window material.

[0011] To improve stability, this invention features an improvement where the two sliding components are symmetrically arranged.

[0012] To improve the strength of the base plate, this utility model has an improvement: the base plate is made of alloy steel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a paddle dryer with uniform drying properties, which has the following beneficial effects:

[0015] This uniformly drying paddle dryer features a cleverly designed crushing mechanism that enables efficient pretreatment of materials. Before the material enters the drying stage, the crushing mechanism further refines the particle size. Smaller particles mean a larger specific surface area, which allows the material to come into more full contact with the heat medium during the subsequent drying process, resulting in more uniform heat transfer and laying the foundation for achieving high-quality drying results.

[0016] Furthermore, this structure features an innovative material distribution and conveying design. Through precise control of the sliding components, the discharge component installed on the housing can move flexibly within the inlet. When material is discharged, the discharge component can evenly convey the material through the inlet to various areas inside the machine, effectively preventing material from accumulating in a certain area. This uniform material distribution greatly improves the uniformity of the drying process, ensuring that each part of the material can be processed under the same drying conditions. This comprehensively improves the uniformity of material drying and significantly enhances product quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4A uniformly drying paddle dryer includes a base plate 1, a machine body 2, a support base 3, a sealing plate 5, and a crushing mechanism 8. One end of the support base 3 is connected to the top of the base plate 1, and the other end of the support base 3 is connected to the bottom of the machine body 2. Several support bases 3 are provided. The top of the machine body 2 has a feed inlet 4. One end of the sealing plate 5 passes through the feed inlet 4. An electromagnet 7 is provided on the outer wall of the feed inlet 4, which attracts the sealing plate 5. A groove 6 is formed on the inner wall of the feed inlet 4, which matches the sealing plate 5. The crushing mechanism 8 includes a sliding component. 9. A housing 10, a crushing assembly 13, a feeding assembly 11, and a discharging assembly 12. The housing 10 is connected to the base plate 1 via the sliding assembly 9. The feeding assembly 11 is located at the center of the top of the housing 10, and the discharging assembly 12 is located at the center of the bottom of the housing 10. The bottom part of the discharging assembly 12 is located inside the feeding port 4. The crushing assembly 13 is located on the top of the housing 10. There are two crushing assemblies 13. There are two sliding assemblies 9. A controller 15 is provided on the base plate 1. The controller 15 is electrically connected to the sliding assembly 9.

[0024] Working principle: such as Figure 1 As shown, when using the equipment, first place it in the designated position. At this time, the base plate 1 serves to support the entire equipment, while the support base 3 further stabilizes the body 2 to ensure the stability of the equipment during operation. Then, connect the equipment to the external mains power to complete the power supply. The specific connection method is common knowledge in this field and will not be described in detail here.

[0025] Subsequently, an appropriate amount of material is added into the chamber 10 through the feeding component 11. After the material is added, the crushing component 13 is started. The dryer is equipped with two crushing components 13, which are composed of a motor, a connecting shaft and a crushing blade, etc. They are arranged in a reasonable manner in the chamber 10 to avoid contact with each other and prevent damage due to collision, which would affect the normal operation of the equipment. After the crushing component 13 is started, it will crush the material into smaller particles, increase the specific surface area of ​​the material, and lay the foundation for subsequent uniform drying.

[0026] After the material is crushed, the discharge assembly 12 is opened, and the material is discharged from the box 10 and enters the machine body 2 through the feed inlet 4. At the same time as the discharge assembly 12 is opened, the operator needs to quickly start the two sliding assemblies 9 through the controller 15. The sliding assembly 9 mainly includes a slide groove, a slider, a motor and a threaded rod. After starting, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the slider to move smoothly on the slide groove, thereby causing the box 10 connected to the slider to be displaced. At this time, the discharge assembly 12 installed at the bottom of the box 10 will move back and forth in the feed inlet 4. During this process, the material discharged by the discharge assembly 12 can be evenly distributed to various areas inside the machine body 2, effectively avoiding the accumulation of material in a certain area of ​​the machine body 2, providing a more uniform material distribution basis for the subsequent drying process, and improving the drying effect and product quality.

[0027] After the material enters the machine body 2, the staff needs to use an external brush to clean the material in the inner wall of the groove 6 of the feed inlet 4 to ensure that the material also falls into the machine body 2 and avoids material residue. After cleaning, the staff turns off the electromagnet 7. The electromagnet 7 loses its attraction to the sealing plate 5 made of martensitic stainless steel. At this time, push the sealing plate 5 so that one end of it can be smoothly inserted into the groove 6. After the sealing plate 5 is installed in place, its other end will not be completely inserted into the feed inlet 4, but will be exposed outside. Then, the electromagnet 7 is turned on again to attract the exposed part of the sealing plate 5, thereby sealing the feed inlet 4.

[0028] After completing the above operations, machine body 2 can be started to dry the material. Machine body 2 adopts a conventional paddle dryer available on the market. Its specific structure and working principle are well known to those skilled in the art, and will not be described in detail here. After the material is dried, it is discharged from the discharge port of machine body 2. When the equipment is finished, in order to prevent external dust from entering the interior of machine body 2 through the feed inlet 4 and affecting the performance of the equipment for the next use, the feed inlet 4 needs to be sealed again with the sealing plate 5 according to the above operating procedure.

[0029] Considering the wear and tear of various components during equipment operation, to ensure stable operation, it is recommended to clean and lubricate the sliding groove and slider of the sliding assembly 9 every 15 days. During cleaning, use a clean, soft cloth to wipe away dust, debris, and other impurities from the surface of the sliding groove and slider. Then, select a suitable lubricating oil for the equipment and apply it evenly to the contact surface of the sliding groove and slider to ensure smooth operation. At the same time, check the attraction force of the electromagnet 7 weekly. A professional magnetic force testing tool can be used to measure whether the attraction force of the electromagnet 7 reaches the specified value (this value can be adjusted according to the actual equipment requirements). If the attraction force is lower than the standard value, the electromagnet 7 needs to be repaired in time to ensure that the sealing plate 5 can effectively seal the feed inlet 4 and prevent external dust from entering the machine body, affecting the material drying effect and equipment performance.

[0030] In this embodiment, to maximize the ease of operation of the equipment, the controller 15 is electrically connected to the crushing component 13 and the machine body 2 respectively. In this way, the operator can easily start and stop the crushing component 13 through the controller 15, and can also flexibly adjust its speed; at the same time, the operating parameters of the machine body 2 can also be controlled, which not only simplifies the operation process, but also significantly improves the overall work efficiency.

[0031] It is worth mentioning that the housing 10 of this device is connected to the slider in the sliding assembly 9 by bolts. When the operator finds that the crushing blade in the crushing assembly 13 is worn or needs to be replaced through the observation window 14, the bolts connecting the housing 10 and the slider can be unscrewed first to separate the housing 10 from the slider. Then, the housing 10 can be replaced with a new crushing assembly 13 that has been assembled inside. The specific structure of the crushing assembly 13 inside the new housing will not be described in detail here.

[0032] In this embodiment, taking into full account the need to observe the internal condition of the box 10 in actual operation, an observation window 14 is specially provided on one side of the box 10. The observation window 14 is installed by embedding it into one side of the box 10. This design does not affect the overall structural strength of the box 10, and allows the operator to intuitively and conveniently observe the crushing state of the material inside the box.

[0033] In this embodiment, in order to effectively enhance the strength of the observation window 14 and ensure its reliability during equipment operation, transparent tempered glass is specially selected as the material of the observation window 14. Transparent tempered glass not only has good transparency, which can meet the needs of observing the internal conditions of the housing 10, but its strength is also much higher than that of ordinary glass, which can effectively resist the influence of external forces such as material collision and vibration, and ensure the stable operation of the equipment.

[0034] In this embodiment, to ensure the stability of the equipment operation, the two sliding components 9 are carefully designed to be symmetrically arranged. This symmetrical layout makes the force on the box 10 more uniform during the movement, effectively avoiding problems such as shaking and displacement caused by uneven force. Whether in the preparation stage before material crushing or in the process of material being uniformly conveyed through the discharge component, the equipment can be guaranteed to operate smoothly and improve the overall working performance.

[0035] In this embodiment, considering that the base plate 1 needs to bear the overall weight of the equipment for a long time, in order to significantly improve its strength and enhance its load-bearing capacity, alloy steel is specially selected to make the base plate 1. Alloy steel has the advantages of high strength, good toughness and fatigue resistance, which can effectively cope with the pressure and vibration generated during the operation of the equipment, ensure that the equipment is placed stably, avoid deformation and damage due to insufficient strength of the base plate, and ensure stable operation of the equipment.

[0036] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
