Description

Technical Field

[0001] This invention belongs to the field of drying and grinding technology, and in particular relates to an integrated drying and grinding device. Background Technology

[0002] Integrated drying and grinding equipment is a highly efficient solution for material handling in industrial production. It combines the processes of drying and grinding materials and is commonly used in industries such as mining, chemicals, food, and pharmaceuticals. This type of equipment is designed to improve production efficiency, reduce intermediate processing steps, save energy, and simplify operating procedures.

[0003] Existing drying and grinding equipment either dries the material first and then grinds it, or grinds it first and then dries it. If the first method is used, the material has a certain blocky structure during drying, so it is necessary to dry the crushed material for a long time, which can easily lead to energy waste. If grinding is done first and then drying, the damp material is prone to sticking to the grinding disc during grinding, which can easily cause blockage of the grinding mechanism, or the ground material may clump together, which can easily lead to uneven drying of the ground material. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to an integrated drying and grinding device, comprising a frame, on which a grinding cylinder, a grinding pre-drying mechanism, and a drying discharge mechanism are sequentially mounted from top to bottom. The grinding cylinder is equipped with a feeding and grinding mechanism for grinding the material to be ground. The grinding pre-drying mechanism includes a hemispherical upper shell, a hemispherical lower shell, and grinding balls. The downward-facing hemispherical upper shell is connected to the grinding cylinder, and the hemispherical lower shell is connected below it. The hemispherical lower shell is connected to the drying discharge mechanism. The hemispherical upper shell and hemispherical lower shell are connected to form a spherical shell, and grinding balls are rotatably mounted inside the spherical shell. Electric heating wires are arranged on the hemispherical upper shell, hemispherical lower shell, and grinding balls.

[0006] The feeding and crushing mechanism includes a feeding hopper, a crushing shaft, and crushing blades. At least two feeding hoppers are symmetrically installed on both sides above the crushing cylinder, and a crushing shaft is vertically rotatably installed inside the crushing cylinder. The top end of the crushing shaft is connected to the output shaft of a servo motor fixed at the top of the crushing cylinder, and multiple sets of crushing blades are installed on the crushing shaft.

[0007] The grinding and pre-drying mechanism also includes an outer ring, a sealing ring, an electric support rod, a support shaft, an electric lifting rod, and a square strip. The corresponding outer ring surfaces of the hemispherical upper and lower shells are fixed with outer rings, and annular grooves are formed on the corresponding outer rings. A sealing ring is installed in each annular groove. The upper and lower outer rings are connected by multiple bolts. The grinding ball is divided into an upper hemisphere and a lower hemisphere. An installation cavity is formed inside the bottom end of the crushing shaft, and an electric support rod is rotatably installed in the installation cavity via a bearing. The bottom end face of the piston rod of the electric support rod is connected to the top of the upper hemisphere. A support shaft is fixed to the lower end face of the lower hemisphere, and the support shaft passes downwards through the drying and discharging mechanism. The bottom of the support shaft is connected to the piston rod of the vertically fixed electric lifting rod. Square holes are formed on the corresponding walls of the upper and lower hemispheres, and a square strip is slidably inserted into each square hole. The upper and lower end faces of the square strip are connected to the hole walls of the upper and lower square holes respectively via springs.

[0008] Furthermore, the drying and discharging mechanism includes a drying cylinder, a stirring shaft tube, spiral blades, a connecting ring, a discharge pipe, a synchronous pulley assembly, and a supporting base plate. The opening of the drying cylinder is connected to the bottom port of the hemispherical lower shell, and a stirring shaft tube is vertically rotatably installed inside the drying cylinder. The bottom end of the stirring shaft tube extends downward to the bottom of the drying cylinder, and spiral blades are sleeved on the stirring shaft tube inside the drying cylinder. The bottom of the stirring shaft tube is connected to the synchronous pulley assembly, and a supporting shaft extends downward inside the stirring shaft tube. At least two connecting rings are fixedly and insulatedly sleeved on the outer ring surface of the supporting shaft, and electromagnetic suction strips are in contact with the inner wall of the stirring shaft tube. The bottom outer ring surface of the drying cylinder is connected to the discharge pipe, and a supporting base plate is provided at the bottom of the drying cylinder. The end side of the supporting base plate is connected to two supporting legs through connecting ear plates. A servo motor connected to the synchronous pulley assembly and an electric lifting rod connected to the supporting shaft are respectively fixed on the supporting base plate.

[0009] Furthermore, an annular boss is formed inside the bottom of the drying cylinder, and the slope of the annular boss is inclined to the cylinder wall of the drying cylinder, and the bottom of the annular boss is aligned with the discharge pipe.

[0010] Furthermore, the frame includes a support plate, support legs, a connecting plate, support rods, and threaded rods. The support plate is fixedly installed on the outer ring surface of the drying cylinder, and multiple support legs are fixed on the lower surface of the support plate. The connecting plate is fixedly installed on the crushing cylinder, and connection holes are opened at corresponding positions on the connecting plate and the support plate. Multiple support rods are arranged between the connecting plate and the support plate, and threaded rods are fixed at both ends of the multiple support rods. The threaded rods at both ends pass downward through the connection holes and are fixed to the support plate and the connecting plate by nuts.

[0011] Furthermore, a metal sleeve is insulatedly installed at the center of the spiral blade, and the metal sleeve is sleeved on the agitator shaft tube. An electromagnetic suction bar is also insulatedly installed on the outer ring surface of the agitator shaft tube.

[0012] Furthermore, the support shaft is a tubular structure with a sealed bottom. A sleeve is rotatably connected to the outer ring of the bottom end of the support shaft via a sealing ring. The inner diameter of the sleeve is larger than the outer diameter of the support shaft. An air guide pipe is connected to the side wall of the sleeve. The sleeve and the tubular support shaft are connected through an air guide hole. An air collection chamber is provided inside the upper plane of the lower hemisphere. The air collection chamber is connected to the upper end of the tubular support shaft. Multiple air jet holes are inclinedly provided on the upper wall of the air collection chamber.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention involves rotating grinding balls inside a spherical shell, both of which are equipped with electric heating wires. The material to be ground and dried is first crushed into uniformly sized blocks by a feeding and crushing mechanism, allowing for uniform grinding and drying. The crushed material falls into a spherical shell formed by connecting a hemispherical upper shell and a hemispherical lower shell. Then, the rotating grinding balls, with electric heating wires on both the ball walls and the spherical shell, simultaneously grind and pre-dry the uniformly sized blocks. This reduces the phenomenon of damp material adhering to the inner wall of the spherical shell or the surface of the grinding balls during grinding, thereby reducing the likelihood of clogging in the grinding and pre-drying mechanism when grinding the crushed material.

[0015] 2. This invention divides the grinding ball into an upper hemisphere and a lower hemisphere, which can slide separately and vertically within the spherical shell. When the grinding cylinder crushes materials, the spherical surface of the upper hemisphere can slide upwards and seal to the lower opening of the grinding cylinder, thus sealing the grinding cylinder. This allows the multiple grinding blades inside the grinding cylinder to fully crush the materials. When the crushed materials are ground, the upper and lower hemispheres connect to form a complete grinding ball, achieving pre-drying of the uniformly crushed materials. When the ground materials fall into the drying cylinder, the upper and lower hemispheres move upwards simultaneously. The upper hemisphere seals the lower opening of the grinding cylinder, while the lower hemisphere seals the upper opening of the drying cylinder. This allows the drying cylinder to fully dry the pre-dried powder. Thus, the upper and lower hemispheres not only perform pre-drying of the crushed materials but also act as seals, respectively sealing the grinding cylinder and the drying cylinder, ensuring that both can fully process the materials to be dried and ground.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0027] Please see Figures 1-6 As shown, the present invention is an integrated drying and grinding device, including a frame 1. The frame 1 is equipped with a crushing cylinder 2, a grinding pre-drying mechanism 3, and a drying discharge mechanism 5 from top to bottom. The crushing cylinder 2 is provided with a feeding crushing mechanism 4 for crushing the material to be ground. The grinding pre-drying mechanism 3 includes a hemispherical upper shell 31, a hemispherical lower shell 32, and grinding balls 33. The hemispherical upper shell 31 with its opening facing downward is connected to the crushing cylinder 2, and the hemispherical lower shell 32 is connected below the hemispherical upper shell 31. The hemispherical lower shell 32 is connected to the drying discharge mechanism 5. The hemispherical upper shell 31 and the hemispherical lower shell 32 are connected to form a spherical shell, and the grinding balls 33 are rotatably installed inside the spherical shell. Electric heating wires are arranged on the hemispherical upper shell 31, the hemispherical lower shell 32, and the grinding balls 33.

[0028] In the design scheme of this invention, when it is necessary to grind and dry materials, the materials are first put into the crushing cylinder 2. The feeding crushing mechanism 4 crushes the materials to be ground and dried into uniformly sized blocks, so that the materials can be ground and dried evenly. The crushed materials in the crushing cylinder 2 fall into the spherical shell formed by the connection of the hemispherical upper shell 31 and the hemispherical lower shell 32. Then, the rotating grinding balls 33, on both the spherical wall and the spherical shell, are equipped with electric heating wires, so that the uniform blocks of materials are ground and pre-dried at the same time. This reduces the phenomenon of damp materials adhering to the inner wall of the spherical shell or the surface of the grinding ball 33 during grinding, thereby reducing the blockage phenomenon of the grinding pre-drying mechanism 3 when grinding the crushed materials. The ground materials fall into the drying discharge mechanism 5, so that the ground and pre-dried powder materials can be quickly dried again, so that the powder materials will not clump. Then, the dried powder materials are discharged through the drying discharge mechanism 5.

[0029] In one embodiment of the present invention, the feeding and crushing mechanism 4 includes a feeding hopper 41, a crushing shaft 42, and crushing blades 43. At least two feeding hoppers 41 are symmetrically installed on both sides above the crushing cylinder 2, and the crushing shaft 42 is vertically rotatably installed inside the crushing cylinder 2. The top end of the crushing shaft 42 is connected to the output shaft of a servo motor fixed to the top of the crushing cylinder 2, and multiple sets of crushing blades 43 are installed on the crushing shaft 42. In the design of the present invention, the material to be crushed is easily fed into the crushing cylinder 2 through at least two feeding hoppers 41. The servo motor drives the crushing shaft 42 to rotate, so that it can drive multiple crushing blades 43 to rotate inside the crushing cylinder 2, so as to crush the material fed into the crushing cylinder 2.

[0030] In one embodiment of the present invention, the grinding pre-drying mechanism 3 further includes an outer ring 34, a sealing ring 35, an electric support rod 36, a support shaft 37, an electric lifting rod 38, and a square strip 39. The corresponding outer ring surfaces of the hemispherical upper shell 31 and the hemispherical lower shell 32 are each fixed with an outer ring 34, and an annular groove is formed on the corresponding upper and lower outer rings 34. A sealing ring 35 is installed in the annular groove. The upper and lower outer rings 34 are connected by multiple bolts. The grinding ball 33 is divided into an upper hemisphere 331 and a lower hemisphere 332. An installation cavity 421 is formed inside the bottom end of the crushing shaft 42. An electric support rod 36 is rotatably mounted inside the 21 via a bearing. The bottom end face of the piston rod of the electric support rod 36 is connected to the top of the upper hemisphere 331. A support shaft 37 is fixed to the lower end face of the lower hemisphere 332, and the support shaft 37 passes downward through the drying discharge mechanism 5. The bottom of the support shaft 37 is connected to the piston rod of the vertically fixed electric lifting rod 38. Square holes 333 are opened on the corresponding walls of the upper hemisphere 331 and the lower hemisphere 332, and a square strip 39 is slidably inserted into the square hole 333. The upper and lower end faces of the square strip 39 are respectively connected to the hole walls of the upper and lower square holes 333 by springs.

[0031] In the design of this invention, the grinding ball 33 is placed between the hemispherical upper shell 31 and the hemispherical lower shell 32, and then the sealing ring 35 is placed in the annular groove, so that the outer rings 34 of the two hemispherical shells come close to each other and fit together. The upper and lower hemispherical shells are sealed and connected by bolts to form a complete spherical shell. When the crushing cylinder 2 needs to crush the material, the piston rod of the electric support rod 36 is controlled to retract, causing it to drive the spherical surface of the upper hemisphere 331 to move upward. At this time, the square strip 39 will slide upward under the pull of the spring above, sealing it. The hemispherical upper shell 31 connects to the crushing cylinder 2. The material to be crushed is then fed into the crushing cylinder 2. The crushing shaft 42 drives multiple crushing blades 43 to crush the material. Thus, the crushing cylinder 2, sealed by the upper hemisphere 331, can fully and uniformly crush the material. After the material is crushed, the piston rod of the electric support rod 36 extends, pushing the upper hemisphere 331 downward to seal and fit against the plane of the lower hemisphere 332. This connects the upper hemisphere 331 and the lower hemisphere 332 to form a complete grinding ball 33, and the crushed material falls onto the spherical shell and the grinding ball 33. Within the grinding chamber formed by the connection, the complete grinding balls 33 are rotated within the connected complete spherical shell via the synchronous belt pulley assembly 56, thus grinding the pulverized material. Simultaneously, the piston rod of the electric support rod 36 extends, while the piston rod of the electric lifting rod 38 retracts, causing the complete grinding balls 33 to move downwards within the complete spherical shell. This reduces the distance between the bottom of the grinding balls 33 and the bottom of the hemispherical lower shell 32, facilitating the pre-drying of the pulverized material to a smaller particle size. Once the grinding balls 33 have completely ground and pre-dried the material, they fall downwards. After entering the drying discharge mechanism 5, the piston rod of the electric lifting rod 38 retracts, causing the spherical surface of the lower hemisphere 332 to move downwards, sealing it at the connection between the lower hemisphere housing 32 and the drying discharge mechanism 5. This allows the drying discharge mechanism 5 to fully dry the ground powder material. During the drying process, the piston rod of the electric support rod 36 retracts, causing the upper hemisphere 331 to move upwards, sealing it at the connection between the upper hemisphere housing 31 and the crushing cylinder 2. This allows the crushing cylinder 2 to continue crushing the material to be ground and dried.

[0032] In one embodiment of the present invention, the drying and discharging mechanism 5 includes a drying cylinder 51, an agitator shaft tube 52, spiral blades 53, a sleeve ring 54, a discharge pipe 55, a synchronous belt pulley assembly 56, and a supporting base plate 57. The opening of the drying cylinder 51 is connected to the bottom port of the hemispherical lower shell 32, and the agitator shaft tube 52 is vertically rotatably installed inside the drying cylinder 51. The bottom end of the agitator shaft tube 52 extends downwards out of the bottom of the drying cylinder 51, and a spiral blade 53 is sleeved on the agitator shaft tube 52 located inside the drying cylinder 51. The bottom of the agitator shaft tube 52 is connected to the synchronous belt pulley assembly 56, and the agitator shaft tube... A support shaft 37 extends downward inside the 52. At least two sleeve rings 54 are fixedly and insulatedly sleeved on the outer ring surface of the support shaft 37. The sleeve rings 54 are insulatedly installed with an electromagnetic suction strip 521 in contact with the inner wall of the stirring shaft tube 52. The bottom outer ring surface of the drying cylinder 51 is connected to a discharge pipe 55. A support base plate 57 is provided at the bottom of the drying cylinder 51. The end side of the support base plate 57 is connected to two support legs 12 through a connecting ear plate. A servo motor connected to the synchronous belt pulley assembly 56 and an electric lifting rod 38 connected to the support shaft 37 are respectively fixed on the support base plate 57.

[0033] In the design of this invention, after the pre-dried powder material has completely fallen into the drying cylinder 51, the spherical surface of the lower hemisphere 332 seals the upper opening of the drying cylinder 51. Then, the heating component inside the drying cylinder 51 operates to heat the drying cylinder 51. Then, through the cooperation of the synchronous belt pulley assembly 56 and the servo motor, the agitator shaft 52 drives the spiral blades 53 to rotate inside the drying cylinder 51. The spiral blades 53 then tumble the material at the bottom and middle of the drying cylinder 51 upwards. Since the top of the drying cylinder 51 is sealed, the upward-tumbled powder material only moves downwards within the drying cylinder 51, thus facilitating thorough drying of the powder material by the drying cylinder 51. Drying process; when the complete grinding ball 33 needs to rotate, the electromagnetic suction bar 521 on the inner wall of the stirring shaft tube 52 needs to be controlled to work, so that it can attract and fix the metal sleeve ring 54. Then the rotation of the stirring shaft tube 52 will drive the support shaft rod 37 to rotate, which will facilitate the grinding ball 33 to rotate in the complete spherical shell to grind the crushed material. When the electromagnetic suction of the sleeve ring 54 is released, the piston rod of the electric lifting rod 38 extends or retracts, which will drive the sleeve ring 54 to slide up and down in the stirring shaft tube 52 through the support shaft rod 37, so that it will not interfere with the normal rotation of the stirring shaft tube 52. The powder material dried in the drying cylinder 51 will be discharged and collected through the discharge pipe 55.

[0034] In one embodiment of the present invention, an annular boss 58 is formed inside the bottom of the drying cylinder 51, and the slope of the annular boss 58 is inclined to the cylinder wall of the drying cylinder 51. The bottom of the annular boss 58 is aligned with the discharge pipe 55. In the design of the present invention, the design of the annular boss 58 facilitates the rapid discharge and collection of the dried material inside the drying cylinder 51 through the discharge pipe 55.

[0035] In one embodiment of the present invention, the frame 1 includes a support plate 11, support legs 12, a connecting plate 13, support rods 14, and threaded rods 15. The support plate 11 is fixedly installed on the outer ring surface of the drying cylinder 51, and multiple support legs 12 are fixed on the lower surface of the support plate 11. The connecting plate 13 is fixedly installed on the crushing cylinder 2, and connecting holes are opened at corresponding positions on the connecting plate 13 and the support plate 11. Multiple support rods 14 are arranged between the connecting plate 13 and the support plate 11, and threaded rods 15 are fixed at both ends of the multiple support rods 14. The threaded rods 15 at both ends pass downward through the connecting holes and are fixed to the support plate 11 and the connecting plate 13 by nuts. In the design of the present invention, the connecting plate 13 and the support plate 11 are detachably connected by the support rods 14 and the threaded rods 15, which facilitates the disassembly and maintenance of the hemispherical upper shell 31 and the hemispherical lower shell 32.

[0036] In one embodiment of the present invention, a metal sleeve 59 is insulatedly installed at the center of the spiral blade 53, and the metal sleeve 59 is sleeved on the stirring shaft tube 52. An electromagnetic suction strip 521 is also insulatedly installed on the outer ring surface of the stirring shaft tube 52. In the design of the present invention, when the stirring shaft tube 52 drives the support shaft 37 to rotate, the electromagnetic suction strip 521 on the outer ring surface of the stirring shaft tube 52 will lose its adsorption and fixation on the metal sleeve 59, so that the spiral blade 53 will be supported in the drying cylinder 51, so that when the grinding ball 33 grinds the pulverized material, the spiral blade 53 will not rotate in the drying cylinder 51. When the spiral blade 53 needs to rotate, the electromagnetic suction strip 521 on the inner wall of the stirring shaft tube 52 will disengage from the adsorption and fixation on the sleeve ring 54, while the electromagnetic suction strip 521 on the outer tube wall will adsorb and fix the metal sleeve 59, so that the stirring shaft tube 52 can drive the spiral blade 53 to rotate in the drying cylinder 51, thereby realizing the turning and drying treatment of powdered materials.

[0037] In one embodiment of the present invention, the support shaft 37 is a tubular structure with its bottom end sealed. The outer ring of the bottom end of the support shaft 37 is rotatably connected to a sleeve 6 through a sealing ring. The inner diameter of the sleeve 6 is larger than the outer diameter of the support shaft 37. The side wall of the sleeve 6 is connected to an air guide pipe 7. The sleeve 6 and the tubular support shaft 37 are connected through an air guide hole. An air collecting chamber 334 is provided inside the upper plane of the lower hemisphere 332. The air collecting chamber 334 is connected to the upper end of the tubular support shaft 37. The upper wall of the air collecting chamber 334 is inclined with multiple air jet holes 335.

[0038] In the design of this invention, to avoid the accumulation of abrasive powder on the upper surface of the lower hemisphere 332 when the upper hemisphere 331 and the lower hemisphere 332 are connected, which would affect the integrity of the connection between the two hemispheres, hot gas is introduced into the sleeve pipe 6 and the tubular support shaft 37 through the air guide pipe 7. Then, the gas is blown into the gap formed between the upper hemisphere 331 and the lower hemisphere 332 through the air collection chamber 334 and multiple air jet holes 335. At this time, the upper hemisphere 331 will block the crushing cylinder 2, which will facilitate the blowing and cleaning of the material accumulated in the gap. At the same time, the hot gas will also enter the spherical shell, so as to blow the residual powder material adhering to the spherical shell into the drying cylinder 51, so that the powder material in the drying cylinder 51 can be quickly discharged through the discharge pipe 55.
