Description

Technical Field

[0001] The present invention relates to the technical field of dryers, in particular to a high-efficiency and energy-saving dryer for bentonite. Background Art

[0002] As an important inorganic non-metallic mineral, bentonite plays a key role in many fields. Its deep-processed products have excellent physical and chemical properties such as adsorption and expansion, and are widely used in oils, coatings, textiles, daily chemicals and environmental protection industries. In the processing of bentonite, drying is an extremely important link, which directly affects product quality and production efficiency. With the development of the industry and increasingly stringent environmental protection requirements, the research and development of high-efficiency and energy-saving dryers for bentonite is imminent. The new dryer can not only improve drying efficiency and ensure product quality, but also reduce energy consumption and pollution, helping enterprises to achieve green and sustainable development, and has broad market prospects. Existing dryers still have the following defects when in use: Bentonite products from the same batch vary significantly in performance due to varying particle sizes and drying levels. Overdrying small particles can alter their internal structure, leading to a loss of key physical and chemical properties such as adsorption and expansion. Larger particles, on the other hand, may retain a significant amount of moisture, which can be released during subsequent applications and affect product stability and performance. For example, using such unevenly dried bentonite in the coatings industry can lead to delamination and caking, seriously impacting the coating's quality and performance.

[0003] Because bentonite dryers are open at both ends, a large amount of hot air escapes, significantly reducing drying efficiency. As the hot air flows through the dryer, it escapes through the openings, preventing it from fully contacting the bentonite for heat transfer. This makes it difficult to achieve optimal drying results. To compensate for this heat loss, the equipment consumes more energy to maintain temperature, which not only increases production costs but also results in energy waste. Summary of the Invention

[0004] In view of the fact that bentonite particles in the existing technology vary in size, small particles are easily over-dried and lose key properties, while large particles are under-dried, resulting in unstable product quality and increased secondary processing costs; the openings at both ends of the dryer cause a large amount of hot air to leak out, reducing drying efficiency and surging energy consumption, which not only increases production costs, but also worsens the working environment, brings safety hazards, and affects stable production operations. Therefore, a high-efficiency and energy-saving bentonite dryer is proposed.

[0005] The present application provides an efficient and energy-saving bentonite dryer, the purpose of which is to: control the drying degree of particles of different sizes to avoid over- or under-drying; at the same time, improve the design of the openings at both ends to reduce the loss of hot air flow, improve drying efficiency, reduce energy consumption and costs, create a safe working environment, and ensure production continuity and stable product quality.

[0009] Furthermore, the trigger component includes a trigger component provided on the dredging component, a reset component provided on the trigger component, a toggle component provided on one side of the trigger component, an energy storage component provided on the toggle component, and a blocking component provided on the toggle component; The trigger assembly includes a cover shell arranged on the separation disk, a through slot arranged on the push box, a threaded rod arranged on the inner plate, a trigger gear arranged on the threaded rod, a trigger rod arranged on the separation disk, the trigger rod passes through the cover shell and is slidably connected to the inner side of the through slot, a first tooth plate is arranged on the trigger rod, and the first tooth plate is meshed with the trigger gear.

[0010] Furthermore, the reset assembly includes a movable groove provided on the trigger rod, a reset slider is provided inside the movable groove, a reset spring is provided between the movable groove and the reset slider, and the reset slider is fixedly connected to the separation disk.

[0014] Furthermore, the separation plate is provided with a separation port at the top of the separation hole.

[0015] Beneficial effects of the present invention: The separation holes and openings of the separation disc allow precise screening of bentonite of varying particle sizes. Smaller bentonite particles preferentially pass through the separation holes and enter the second drying drum. Larger bentonite particles have an extended drying time within the first drying drum, remaining fully dried by the time they enter the second drying drum through the opening. This size-based time-difference drying mechanism avoids the problems encountered in conventional dryers, such as overdrying of small particles, which can lead to loss of key properties like adsorption and expansion, and underdrying of larger particles, which can affect subsequent applications. This ensures consistent performance within each batch of products, meeting the stringent bentonite quality requirements of the coatings, oils, and grease industries.

[0016] The closed structure of the heating cylinder outside the drying cylinder reduces heat leakage, significantly improving energy efficiency compared to the heat loss caused by openings at both ends of traditional dryers. Furthermore, the rotation of the first drying cylinder automatically drives the dredging component through a gear transmission, eliminating the need for an additional power source and reducing energy consumption. The push box and dredging column promptly clear the separation holes in the separation disc, preventing drying stagnation caused by blockage, ensuring the continuity of the drying process, increasing the drying output per unit time, and reducing overall energy consumption, helping companies achieve green production.

[0017] A cam pushes the trigger lever, which, through gear transmission, precisely inserts the dredging rod into the separation hole to clear the blockage, eliminating manual intervention and reducing downtime for maintenance. The second soft belt of the sealing assembly works with the sealing block to form a flexible sealing barrier, effectively preventing bentonite from entering the housing. This protects gears and other transmission components from contamination, extending the equipment's service life, reducing maintenance costs due to component wear, and improving the dryer's operational stability and reliability.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example 1, with reference to Figures 1-8 , which is the first embodiment of the present invention, provides a high-efficiency and energy-saving bentonite dryer, including a base 1, a first drying cylinder 11 is rotatably connected to the top of the base 1, a second drying cylinder 12 is also rotatably connected to the top of the base 1, a separation disk 13 is rotatably connected between the first drying cylinder 11 and the second drying cylinder 12, the separation disk 13 is fixedly connected to the base 1, the end of the first drying cylinder 11 is rotatably connected to a first end cover 14, the first end cover 14 is fixedly connected to the base 1, the top of the first end cover 14 is fixedly connected to a feed port 15, the end of the second drying cylinder 12 is rotatably connected to a second end cover 16, the second end cover 16 is fixedly connected to the base 1, the bottom of the second end cover 16 is fixedly connected to a discharge port 17, the outer sides of the first drying cylinder 11 and the second drying cylinder 12 are fixedly sleeved with a heating Cylinder 18, the heating cylinder 18 is fixedly connected to the base 1, and also includes a separation unit installed between the first drying cylinder 11 and the second drying cylinder 12; the separation unit includes a dredging component and a trigger component installed on the separation disc 13, the dredging component includes a dredging assembly 2 installed on the separation disc 13, the top of the dredging assembly 2 is installed with a lifting assembly 3, and one side of the lifting assembly 3 is installed with a driving assembly 4; the dredging component is used to dredge the separation disc 13, and the trigger component is used to drive the dredging component; the dredging assembly 2 includes a separation hole opened on the separation disc 13, and a push box 21 is slidably connected to the separation disc 13, and the inner side of the push box 21 is limitedly slidably connected to the inner plate 22, and a dredging column 23 is fixedly connected to the inner plate 22, and the dredging column 23 is plugged into the inner side of the separation hole.

[0022] Specifically, bentonite enters the first drying drum 11 through the feed port 15. It is then heated and dried by heating drums 18 located outside the first and second drying drums 11, 12. During the drying process, the first and second drying drums 11, 12 rotate, causing the bentonite to tumble and move sideways, ensuring even heating. The bentonite then passes through a separation tray 13 and into the second drying drum 12 for further drying. The separation holes in the separation tray 13 provide preliminary screening for the bentonite, allowing smaller, more dry bentonite to pass through the holes preferentially and enter the second drying drum 12. Larger, less dry bentonite remains in the first drying drum 11 and continues drying, separating the large and small bentonite particles. After drying in the second drying drum 12, the small bentonite particles are discharged through the discharge port 17, completing drying. The larger bentonite particles continue to dry in the first and second drying drums 11, 12. During drying, the smaller bentonite particles spend less time in the drying drum than the larger bentonite particles. Due to the time difference, the bentonite with smaller particles will not be over-dried, and the bentonite with larger particles will not be under-dried.

[0023] If the separation hole becomes clogged, the trigger component will drive the unblocking component to operate, and the drive component 4 will drive the lifting component 3 to operate. The lifting component 3 will control the push box 21 of the unblocking component 2 to slide on the separation disk 13. The push box 21 will scrape the bentonite on the separation disk 13. At the same time, the inner plate 22 will drive the unblocking column 23 to slide within the push box 21. When the unblocking column 23 is aligned with the clogged separation hole, the unblocking column 23 will be inserted into the separation hole and push out the blockage, thereby unblocking the separation disk 13 and ensuring smooth transportation of the bentonite. This effectively solves the problem of uneven drying caused by different particle sizes in traditional dryers. At the same time, the closed drying cylinder structure reduces the leakage of hot air, improves drying efficiency, and achieves efficient and energy-saving drying.

[0024] Reference Figure 6 and Figure 7 The lifting assembly 3 includes a slide 31 fixedly connected to the separation disc 13, a reciprocating screw rod 32 is rotatably connected to the inner side of the slide 31, a slide plate 33 is threadedly connected to the reciprocating screw rod 32, the slide plate 33 is fixedly connected to the push box 21, the slide plate 33 is slidably connected to the inner side of the slide 31, and a first soft belt 34 is slidingly connected to the open end of the slide 31, and the first soft belt 34 is fixedly connected between the slide plate 33 and the top inner wall of the slide 31.

[0025] Specifically, the reciprocating screw 32 rotates in the chute 31. Since the slide 33 is threadedly connected to the reciprocating screw 32 and can slide inside the chute 31, according to the principle of threaded transmission, the rotation of the reciprocating screw 32 will be converted into a linear reciprocating motion of the slide 33 along the direction of the chute 31. The slide 33 is fixedly connected to the push box 21, so the movement of the slide 33 can directly drive the push box 21 to move synchronously on the separation disk 13. During the movement of the slide 33, the first soft belt 34 acts to block the bentonite. One end of the first soft belt 34 is fixed to the slide 33, and the other end is connected to the top inner wall of the chute 31. This prevents the bentonite from entering the chute 31 when the slide 33 slides in the chute 31, blocking the chute 31 and affecting the rotation of the reciprocating screw 32, thereby ensuring the normal operation of all components. This ensures the smooth transportation of bentonite in the dryer and avoids problems such as reduced drying efficiency and unstable product quality due to blockage of the separation disk 13.

[0026] Reference Figure 8 The driving assembly 4 includes an internal gear 41 fixedly connected to the first drying cylinder 11, and a spur gear 42 is meshedly connected to the inner side of the internal gear 41. A first bevel gear 43 is fixedly connected to one side of the spur gear 42. The bottom of the first bevel gear 43 is meshedly connected to the second bevel gear 44. The bottom of the second bevel gear 44 is fixedly connected to a connecting shaft 45. The connecting shaft 45 is rotatably connected to the separation disk 13, and the bottom of the connecting shaft 45 is fixedly connected to the reciprocating screw 32. The outer side covers of the first bevel gear 43 and the second bevel gear 44 are provided with an outer box 46. The connecting shaft 45 is rotatably connected to the outer box 46, and the outer box 46 is fixedly connected to the separation disk 13.

[0027] Specifically, when the first drying cylinder 11 rotates, the internal gear 41 fixed thereto rotates accordingly, driving the meshing spur gear 42 with it. The spur gear 42 then transmits power to the first bevel gear 43 fixed thereto. The first bevel gear 43, through meshing with the second bevel gear 44, changes the direction of power transmission, causing the second bevel gear 44 to begin rotating. The connecting shaft 45 fixedly connected to the bottom of the second bevel gear 44 is rotationally connected to the separation disc 13, so the connecting shaft 45 rotates synchronously with the second bevel gear 44. Since the bottom of the connecting shaft 45 is fixedly connected to the reciprocating screw 32, it drives the reciprocating screw 32 to rotate within the chute 31. The outer box 46 protects the first bevel gear 43 and the second bevel gear 44, preventing bentonite from entering and affecting the transmission, ensuring the stable operation of the drive assembly 4 and enabling the dredging components to function promptly and effectively.

[0028] Example 2, reference Figures 9-14, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the trigger component includes a trigger component 5 installed on the dredging component 2, a reset component 6 is installed on the trigger component 5, a toggle component 7 is installed on one side of the trigger component 5, an energy storage component 8 is installed on the toggle component 7, and a blocking component 9 is also installed on the toggle component 7; the trigger component 5 includes a cover shell 51 fixedly connected to the separation disk 13, a through groove is opened on the push box 21, a threaded rod 52 is threadedly connected to the inner plate 22, and a trigger gear 53 is fixedly connected to the threaded rod 52. The upper limit position of the separation disk 13 is slidably connected to the trigger rod 54, the trigger rod 54 passes through the cover shell 51 and is slidably connected to the inner side of the through groove, and a first tooth plate 55 is fixedly connected to the trigger rod 54, which is meshed with the trigger gear 53.

[0029] Specifically, when the trigger rod 54 slides, the first toothed plate 55 affixed thereto moves accordingly, meshing with the trigger gear 53. As the first toothed plate 55 continues to move, the trigger gear 53 begins to rotate. Since the trigger gear 53 is fixed to the threaded rod 52, the threaded rod 52 also rotates. Because the threaded rod 52 is threadedly connected to the inner plate 22, the rotation of the threaded rod 52 is converted into linear sliding of the inner plate 22 within the push box 21 through the threaded transmission. As the inner plate 22 slides, it drives the dredging post 23 affixed thereto, allowing it to precisely insert into the clogged separation hole, pushing out the blocked bentonite and completing the dredging of the separation hole. Under the action of the reset assembly 6, the trigger rod 54 is reset, causing the first toothed plate 55 to reset, causing the trigger gear 53 to rotate once forward and once backward, causing the threaded rod 52 to rotate back and forth. The instantaneous reciprocating movement of the inner plate 22 within the push box 21 allows the dredging post 23 to be quickly inserted into and then quickly removed from the separation hole. Ensure smooth transportation of bentonite in the dryer.

[0030] Reference Figure 12 The reset assembly 6 includes a moving groove opened on the trigger rod 54, a reset slider 61 is slidably connected to the inside of the moving groove, a reset spring 62 is fixedly connected between the moving groove and the reset slider 61, and the reset slider 61 is fixedly connected to the separation disk 13.

[0031] Specifically, when the trigger rod 54 slides due to an external force, the reset slider 61 slides within the movable groove of the trigger rod 54, compressing the reset spring 62, which accumulates elastic potential energy. When the external force disappears, the reset spring 62 releases its elastic potential energy, pushing the reset slider 61 to slide in the opposite direction within the movable groove. Because the reset slider 61 is fixedly connected to the separation disc 13, its reverse sliding movement drives the trigger rod 54 to return to its initial position along the separation disc 13. During the reset process of the trigger rod 54, the meshing transmission between the first toothed plate 55 and the trigger gear 53 causes the threaded rod 52 to reverse, driving the inner plate 22 and the dredging column 23 back to their initial positions, completing the reset of the entire trigger mechanism and preparing for subsequent dredging operations.

[0032] Reference Figure 13 The toggle assembly 7 includes an L-shaped plate 71 slidably connected to the cover 51, the L-shaped plate 71 is fixedly connected to the push box 21, and a toggle shaft 72 is rotatably connected to the L-shaped plate 71. One end of the toggle shaft 72 is fixedly connected to a cam 73, and the side wall of the cam 73 is in contact with the trigger rod 54.

[0033] Specifically, when the toggle shaft 72 rotates, it drives the cam 73 fixed thereto to rotate synchronously. As the cam 73 rotates, its unique profile contacts the trigger rod 54. When the raised portion of the cam 73 rotates to face the trigger rod 54, it applies a thrust to the trigger rod 54, pushing it to one side. As the trigger rod 54 slides, the meshing transmission between the first toothed plate 55 and the trigger gear 53 drives the threaded rod 52 to rotate, causing the inner plate 22 to slide within the push box 21, driving the dredging column 23 into the separation hole to dredge the block. When the cam 73 rotates one full circle and the raised portion rotates away from the trigger rod 54, the external force disappears, and the reset assembly 6 takes effect. Under the elastic force of the reset spring 62, the reset assembly 6 drives the trigger rod 54 to reset, causing the dredging column 23 to be withdrawn from the separation hole and return to its initial position, completing a complete dredging and reset operation.

[0034] Reference Figure 14 The energy storage assembly 8 includes a torsion spring 81 fixedly connected between the toggle shaft 72 and the L-shaped plate 71. The torsion spring 81 is sleeved on the toggle shaft 72. The other end of the toggle shaft 72 is fixedly connected to the energy storage gear 82. The separation disc 13 is also fixedly connected to a second tooth plate 83, and the second tooth plate 83 is meshed with the energy storage gear 82.

[0035] Specifically, under the action of the lifting assembly 3, the push box 21 is driven to move, causing the L-shaped plate 71 to move, and through the toggle shaft 72, the energy storage gear 82 is driven to move. Under the action of the second tooth plate 83, the energy storage gear 82 rotates, driving the toggle shaft 72 to rotate, causing the torsion spring 81 to twist and store energy. When the energy storage gear 82 is separated from the second tooth plate 83, the torsion spring 81 will release energy, driving the toggle shaft 72 to rotate, causing the cam 73 to rotate one circle. A one-way bearing is provided between the toggle shaft 72 and the energy storage gear 82. When the energy storage gear 82 moves upward, it encounters the second tooth plate 83, and the energy storage gear 82 rotates, but the toggle shaft 72 does not rotate, preventing the cam 73 from rotating again and interfering with the trigger rod 54. The rest of the structure is the same as that of Example 1.

[0036] Example 3, reference Figure 9 and Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the blocking assembly 9 includes a slot provided on the cover shell 51, a blocking block 91 is slidably connected to the inner side of the slot, the blocking block 91 is fixedly connected to the L-shaped plate 71, and a second soft belt 92 is slidably connected to the open end of the slot, and the second soft belt 92 is fixedly connected between the blocking block 91 and the inner wall of the top of the slot.

[0037] Specifically, when the L-shaped plate 71 moves with the push box 21, the blocking block 91 fixed on the L-shaped plate 71 slides synchronously in the slot of the cover 51. One end of the second soft belt 92 at the open end of the slot is connected to the blocking block 91, and the other end is fixed to the inner wall of the top of the slot. During the sliding process of the blocking block 91, the second soft belt 92 always remains connected to the blocking block 91. The blocking block 91 slides toward the inside of the slot, and the second soft belt 92 unfolds and covers the slot opening, forming a flexible sealing barrier, which effectively blocks bentonite particles from entering the interior of the cover 51 through the slot, protecting the internal transmission components from contamination. The blocking block 91 returns to its initial position, and the second soft belt 92 shrinks accordingly, pushing the side wall of the box 21 to seal the bottom of the slot, continuously playing a dust-proof role, and ensuring the stable operation of the entire trigger mechanism.

[0038] Reference Figure 3 and Figure 4 The separation plate 13 is located at the top of the separation hole and is provided with a separation opening 10.

[0039] Specifically, as bentonite is transported within the first drying drum 11, small particles are passed through the separation holes into the second drying drum 12. Large particles are pushed up by the side of the separation disc 13 and then passed through the separation port 10 into the second drying drum 12. This ensures that small particles are always discharged from the drying drum before large particles. This ensures that bentonite of varying particle sizes can be fully dried, preventing overdrying or underdrying. The remaining structure is the same as that of Example 2.

[0040] Based on Examples 1-3, the working principle of the present invention is as follows: Bentonite enters the first drying drum 11 from the feed port 15, where it is heated by the outer heating drum 18. The first and second drying drums 11 and 12 rotate, causing the bentonite to tumble and transfer to one side, ensuring uniform heating. The separation holes and separation port 10 on the separation disc 13 enable particle screening. Small, well-dried bentonite enters the second drying drum 12 through the separation holes, while large, poorly dried bentonite continues to dry in the first drying drum 11 and is fully dried by the time it enters the second drying drum 12 from the separation port 10. By controlling the difference in the particle residence time within the drums, overdrying of small particles and underdrying of large particles are avoided. During the drying process, the first drying cylinder 11 rotates, driving the internal gear 41 to rotate. The rotation is then transmitted through the spur gear 42, the first bevel gear 43, and the second bevel gear 44, so that the connecting shaft 45 drives the reciprocating screw 32 to rotate in the chute 31. The slide 33 performs reciprocating linear motion, driving the push box 21 to move on the separation disc 13. The push box 21 scrapes the bentonite on the separation disc 13. At the same time, the first soft belt 34 prevents the bentonite from entering the chute 31. If the separation hole is blocked, the L-shaped plate 71 drives the toggle shaft 72 to move, the energy storage gear 82 engages and rotates with the second tooth plate 83, and the torsion spring 81 stores energy. After separation, the torsion spring 81 releases energy to drive the toggle shaft 72 to rotate, and the cam 73 pushes the trigger rod 54 to slide, and the first tooth plate 55 drives the trigger gear 53 to rotate. The threaded rod 52 makes the inner plate 22 slide, and the dredging column 23 is inserted into the separation hole to dredge. At the same time, the blocking block 91 slides in the slot, and the second soft belt 92 covers the slot to prevent bentonite from entering the cover 51. After dredging is completed, the reset spring 62 drives the trigger rod 54 to reset, and the dredging column 23 retreats, solving the problems of uneven particle drying and hot air leakage.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
