Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a three-in-one equipment for filtration, washing and drying of a cylindrical cone type. Background Technology

[0002] The filter washing and drying machine is a process testing instrument used in the field of chemical engineering. It is a three-in-one device integrating filtration, washing, and drying functions, primarily used in the pharmaceutical and fine chemical industries for processing sterile raw materials and heat-sensitive materials. The equipment also integrates multiple functions such as reaction, extraction, and crystallization. This equipment is also widely used in the food, chemical, pharmaceutical, and environmental protection industries. The equipment adopts a double-cone or cylindrical-cone closed structure, equipped with a stirring device, a filtration system such as a sintered metal mesh or filter cloth, and an intelligent control system to achieve fully closed-loop operation.

[0003] Chinese Patent 2020229080202 discloses a conical filtration, washing, and drying three-in-one multifunctional device, characterized by comprising: a multifunctional filter cylinder, an internally heated hollow spiral ribbon stirring device, and a multifunctional base plate. The upper section of the multifunctional filter cylinder is cylindrical, and the lower section is an inverted frustum-shaped cylindrical structure. The multifunctional base plate is installed at the bottom of the lower section of the multifunctional filter cylinder. A pulse vacuum filter bag is installed on the upper right side of the multifunctional filter cylinder, and a material inlet is opened on the upper left side of the multifunctional filter cylinder. The internally heated hollow spiral ribbon stirring device includes: a stirring main shaft, an internally heated hollow spiral ribbon, and a driving device. The stirring main shaft is installed inside the multifunctional filter cylinder and extends through the middle of the upper end of the multifunctional filter cylinder to connect with the driving device. The stirring main shaft and the multifunctional filter... The cylinder is sealed by a double-end mechanical seal. The internally heated hollow helical ribbon is located inside the cylinder of the multi-functional filter and is mounted on the stirring main shaft via a support rod. The stirring main shaft, the internally heated hollow helical ribbon, and the support rod are interconnected hollow structures, and a heating medium flows inside the main shaft, the internally heated hollow helical ribbon, and the support rod. A filter assembly is installed on the inner wall of the multi-functional filter cylinder. The filter assembly includes a straight section filter and a segmented conical filter. The straight section filter is installed on the inner wall of the upper section of the multi-functional filter cylinder, and the segmented conical filter is installed on the lower section of the multi-functional filter cylinder. The upper end of the segmented conical filter is sealed to the lower end of the straight section filter. A sealing sleeve is provided between the upper end of the straight section filter and the inner wall of the multi-functional filter cylinder, and between the lower end of the segmented conical filter and the inner wall of the multi-functional filter cylinder.

[0004] In the aforementioned patent, during stirring, filtering, washing, and drying, the stirring spindle rotates clockwise to lift the material upwards, thereby improving processing efficiency. When discharge is required, the stirring spindle rotates counterclockwise to push the material downwards towards the discharge port. However, when the stirring spindle is rotating to discharge the material, the heated hollow spiral ribbon does not contact the inner wall of the cylinder. Therefore, some material will still remain on the inner wall of the cylinder and cannot be cleaned off, resulting in reduced output, material waste, and inconvenience for subsequent cleaning. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-in-one device for filtration, washing and drying of a cylindrical cone type, so as to solve the above problems.

[0006] The technical solution of this utility model is implemented as follows: A three-in-one device for filtering, washing, and drying in a cylindrical cone shape includes a cylindrical body, a drive mechanism is installed at the top of the cylindrical body, the drive mechanism is connected to a drive shaft extending into the cylindrical body, and further includes:

[0007] The driven sleeve is hollow inside and rotatably connected to the cylinder. The driven sleeve is sleeved on the outside of the drive shaft and coaxially arranged. The drive shaft rotates relative to the driven sleeve. The driven sleeve and the drive shaft are linked by a transmission mechanism. The outer wall of the driven sleeve is provided with a stirring ribbon.

[0008] The scraper is close to and adapted to the inner wall of the cylinder. The scraper is connected to the drive shaft and the driven sleeve through a reversing telescopic mechanism.

[0009] When the drive shaft rotates counterclockwise, the scraper does not contact the inner wall of the cylinder; when the drive shaft rotates clockwise, the reversing telescopic mechanism drives the scraper to approach and contact the inner wall of the cylinder.

[0010] By adopting the above technical solution, when the drive shaft rotates counterclockwise, the driven sleeve and the stirring screw ribbon are simultaneously driven to rotate counterclockwise through the transmission mechanism, lifting the material upward. Under the action of the direction-changing telescopic mechanism, there is a gap between the scraper and the inner wall of the cylinder, and they have not yet made contact. When it is necessary to discharge the material, when the drive shaft rotates clockwise, the driven sleeve and the stirring screw ribbon are simultaneously driven to rotate clockwise through the transmission mechanism, pushing the material downward. At the same time, through the action of the direction-changing telescopic mechanism, the scraper moves closer to and makes contact with the inner wall of the cylinder, thereby scraping off the residual material on the inner wall, making the discharge cleaner and the cleaning effect better. No manual adjustment is required, and it can automatically operate according to the rotation direction of the drive shaft, making it more convenient to use.

[0011] The present invention is further configured such that: the transmission mechanism includes a fixing block fixed on the inner wall of the driven sleeve, and a first abutting block and a second abutting block fixed on the outer wall of the drive shaft;

[0012] The fixed block is located on the moving path of the first abutting block and the second abutting block. When the drive shaft rotates counterclockwise, the first abutting block abuts against the fixed block, causing the driven sleeve to rotate counterclockwise; when the drive shaft rotates clockwise, the second abutting block abuts against the fixed block, causing the driven sleeve to rotate clockwise.

[0013] By adopting the above technical solution, the drive shaft can drive the driven sleeve and the stirring ribbon to rotate synchronously, whether it rotates clockwise or counterclockwise.

[0014] The present invention is further configured such that the reversing telescopic mechanism includes:

[0015] An extension sleeve protrudes from the side wall of the driven sleeve and communicates with the interior of the driven sleeve.

[0016] A connecting rod, one end of which is connected to a scraper, and the other end of which is slidably connected inside an extension sleeve;

[0017] A transmission rod that slides within an extension sleeve, with both ends abutting between the drive shaft and the connecting rod, respectively.

[0018] An ejector block is disposed on the outer wall of the drive shaft. The ejector block includes an elongation section and a fan-shaped section. The thickness of the elongation section gradually increases from one side to the other along the circumference of the drive shaft. The thickness of the fan-shaped section remains uniform. The fan-shaped section is connected to the side of the elongation section with a larger thickness and transitions smoothly.

[0019] One end of the transmission rod abuts against the outer wall of the drive shaft or the outer wall of the ejector block as the drive shaft rotates; when the transmission rod abuts against the drive shaft, the scraper does not contact the inner wall of the cylinder; when the transmission rod abuts against the outer wall of the sector, the scraper contacts the inner wall of the cylinder.

[0020] By adopting the above technical solution, when the drive shaft rotates counterclockwise, one end of the transmission rod abuts against the outer wall of the drive shaft, and at this time, the scraper does not contact the inner wall of the cylinder. When the drive shaft rotates clockwise, the transmission rod moves along the side with less thickness of the extension section to the side with greater thickness, thereby gradually moving away from the drive shaft, and at the same time pushing the connecting rod away from the drive shaft. When the drive shaft rotates to the point where the transmission rod abuts against the sector section, the scraper contacts the inner wall of the cylinder, and at the same time, the second abutting block abuts against the fixing block. At this time, the drive shaft is stationary relative to the driven sleeve. The drive shaft continues to rotate clockwise, driving the driven sleeve, the stirring ribbon, and the scraper to rotate and discharge material. This achieves the following: when the drive shaft rotates counterclockwise, the connecting rod does not extend; when the drive shaft rotates clockwise, it pushes the connecting rod to extend. The extension and retraction of the connecting rod is achieved according to the rotation direction of the drive shaft, without manual operation, making it more convenient to use.

[0021] The present invention is further configured such that the reversing telescopic mechanism also includes:

[0022] The first spring is located between the connecting rod and the extension sleeve and is used to apply a force close to the drive shaft to the connecting rod.

[0023] The second spring is located between the transmission rod and the connecting rod;

[0024] The elastic force of the second spring is greater than that of the first spring.

[0025] By adopting the above technical solution, the first spring can effectively press the transmission rod against the drive shaft, ensuring that the transmission rod always remains in contact with the drive shaft or the ejector block, making the transmission more stable. When the transmission rod contacts the ejector block, the transmission rod is pushed out, thereby compressing the first spring and pushing out the connecting rod. When the scraper contacts the inner wall of the cylinder, if it encounters a hard material that the scraper cannot scrape off in one go, the scraper will be pushed away, causing the connecting rod to compress the second spring, giving the scraper a certain elasticity with the inner wall of the cylinder, thus avoiding damage to the scraper or the inner wall of the cylinder.

[0026] The present invention is further configured such that: a blind hole for the transmission rod to extend into is provided on one end of the connecting rod near the transmission rod, and the second spring is provided between the bottom of the blind hole and the transmission rod.

[0027] By adopting the above technical solution, the connection and transmission between the connecting rod and the transmission rod can be made more stable and more space-saving.

[0028] The present invention is further configured such that the end of the transmission rod near the drive shaft is arc-shaped.

[0029] By adopting the above technical solution, the sliding of the transmission rod on the outer wall of the ejector block becomes smoother. Attached Figure Description

[0035] 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.

[0036] like Figures 1-4 As shown, this utility model discloses a three-in-one device for filtering, washing and drying in a cylindrical cone shape, including a cylindrical body 1, a driven sleeve 31 and a scraper 4. A drive mechanism 2 is installed on the top of the cylindrical body 1, and the drive mechanism 2 is connected to a drive shaft 30 that extends into the cylindrical body 1. A stirring screw ribbon 310 is provided on the outer wall of the driven sleeve 31.

[0037] The driven sleeve 31 is hollow inside and rotatably connected inside the cylinder 1. The driven sleeve 31 is sleeved on the outside of the drive shaft 30 and coaxially arranged. The drive shaft 30 rotates relative to the driven sleeve 31. The driven sleeve 31 and the drive shaft 30 are linked by a transmission mechanism.

[0038] The transmission mechanism includes a fixed block 311 fixed to the inner wall of the driven sleeve 31, and a first abutment block 300 and a second abutment block 301 fixed to the outer wall of the drive shaft 30. The fixed block 311 is located on the moving path of the first abutment block 300 and the second abutment block 301. When the drive shaft 30 rotates counterclockwise, the first abutment block 300 abuts against the fixed block 311, causing the driven sleeve 31 to rotate counterclockwise. When the drive shaft 30 rotates clockwise, the second abutment block 301 abuts against the fixed block 311, causing the driven sleeve 31 to rotate clockwise. This ensures that the drive shaft 30 can drive the driven sleeve 31 and the stirring ribbon 310 to rotate synchronously regardless of whether it rotates clockwise or counterclockwise.

[0039] The scraper 4 is close to and adapted to the inner wall of the cylinder 1. The scraper 4 is connected to the drive shaft 30 and the driven sleeve 31 through the reversing telescopic mechanism 8. When the drive shaft 30 rotates counterclockwise, the scraper 4 does not contact the inner wall of the cylinder 1. When the drive shaft 30 rotates clockwise, the reversing telescopic mechanism 8 drives the scraper 4 to approach and contact the inner wall of the cylinder 1.

[0040] When the drive shaft 30 rotates counterclockwise, it synchronously drives the driven sleeve 31 and the stirring screw ribbon 310 to rotate counterclockwise through the transmission mechanism, lifting the material upward. Under the action of the reversing telescopic mechanism 8, there is a gap between the scraper 4 and the inner wall of the cylinder 1, and they have not yet made contact. When it is necessary to discharge the material, when the drive shaft 30 rotates clockwise, it synchronously drives the driven sleeve 31 and the stirring screw ribbon 310 to rotate clockwise through the transmission mechanism, pushing the material downward. At the same time, through the action of the reversing telescopic mechanism 8, the scraper 4 moves closer to and makes contact with the inner wall of the cylinder 1, thereby scraping off the material remaining on the inner wall, making the discharge cleaner and the cleaning effect better. No manual adjustment is required, and it can automatically operate according to the rotation direction of the drive shaft 30, making it more convenient to use.

[0041] In this embodiment of the utility model, the reversing telescopic mechanism 8 includes an extension sleeve 80, a connecting rod 81, a transmission rod 82, and an ejector block 83;

[0042] The extension sleeve 80 protrudes from the side wall of the driven sleeve 31 and communicates with the interior of the driven sleeve 31.

[0043] One end of the connecting rod 81 is connected to the scraper 4, and the other end is slidably connected in the extension sleeve 80. A first spring 84 is provided between the connecting rod 81 and the extension sleeve 80. The first spring 84 is used to apply a force close to the drive shaft 30 to the connecting rod 81.

[0044] The transmission rod 82 slides within the extension sleeve 80, and its two ends abut against the drive shaft 30 and the connecting rod 81 respectively. A second spring 85 is provided between the transmission rod 82 and the connecting rod 81, and the elastic force of the second spring 85 is greater than that of the first spring 84.

[0045] The ejector block 83 is disposed on the outer wall of the drive shaft 30. The ejector block 83 includes an extension portion 830 and a fan-shaped portion 831. The thickness of the extension portion 830 gradually increases from one side to the other along the circumference of the drive shaft 30. The thickness of the fan-shaped portion 831 remains uniform. The fan-shaped portion 831 is connected to the side of the extension portion 830 with a larger thickness and transitions smoothly.

[0046] One end of the transmission rod 82 abuts against the outer wall of the drive shaft 30 or the outer wall of the ejector block 83 as the drive shaft 30 rotates; when the transmission rod 82 abuts against the drive shaft 30, the scraper 4 does not contact the inner wall of the cylinder 1; when the transmission rod 82 abuts against the outer wall of the fan-shaped part 831, the scraper 4 contacts the inner wall of the cylinder 1.

[0047] The first spring 84 effectively presses the transmission rod 82 against the drive shaft 30, ensuring that the transmission rod 82 remains in contact with the drive shaft 30 or the ejector block 83, thus making the transmission more stable. When the transmission rod 82 contacts the ejector block 83, the transmission rod 82 is pushed out, thereby compressing the first spring 84 and pushing out the connecting rod 81. When the scraper 4 contacts the inner wall of the cylinder 1, if it encounters a hard material that the scraper 4 cannot scrape off in one go, the scraper 4 will be pushed away, thereby compressing the connecting rod 81 and the second spring 85, giving the scraper 4 a certain degree of elasticity with the inner wall of the cylinder 1, thus avoiding damage to the scraper 4 or the inner wall of the cylinder 1.

[0048] When the drive shaft 30 rotates counterclockwise, one end of the transmission rod 82 abuts against the outer wall of the drive shaft 30, and at this time, the scraper 4 does not contact the inner wall of the cylinder 1; when the drive shaft 30 rotates clockwise, the transmission rod 82 moves along the side of the growing part 830 with a smaller thickness to the side with a larger thickness, thereby gradually moving away from the drive shaft 30, and at the same time pushing the connecting rod 81 away from the drive shaft 30. When the drive shaft 30 rotates to the point where the transmission rod 82 abuts against the sector part 831, the scraper 4 contacts the inner wall of the cylinder 1, and at the same time... At the same time, the second abutting block 301 and the fixed block 311 also abut against each other. At this time, the drive shaft 30 is stationary relative to the driven sleeve 31. The drive shaft 30 continues to rotate clockwise, driving the driven sleeve 31, the stirring screw 310 and the scraper 4 to rotate and discharge materials. When the drive shaft 30 rotates counterclockwise, the connecting rod 81 does not extend. When the drive shaft 30 rotates clockwise, it pushes the connecting rod 81 to extend. The extension and retraction of the connecting rod 81 is realized according to the rotation direction of the drive shaft 30. No manual operation is required, making it more convenient to use.

[0049] In this embodiment of the invention, a blind hole 810 is provided on the end of the connecting rod 81 near the transmission rod 82 for the transmission rod 82 to extend into. The second spring 85 is disposed between the bottom of the blind hole 810 and the transmission rod 82. This makes the connection and transmission between the connecting rod 81 and the transmission rod 82 more stable and saves more space.

[0050] In this embodiment of the invention, the end of the transmission rod 82 near the drive shaft 30 is designed with an arc shape. This allows the transmission rod 82 to slide more smoothly on the outer wall of the ejector block 83.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
