Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a vacuum mixing drying equipment. Background Technology

[0002] Drying equipment is widely used in many industries such as food, pharmaceuticals, and chemicals; vacuum dryers are specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances, and can be filled with inert gas, especially for some complex items that can be dried quickly.

[0003] Patent (CN217275367U) discloses a vacuum mixing dryer, relating to the technical field of dryers. It includes a housing and an air pipe connected to the top of the housing. A mixing assembly is disposed inside the housing, comprising a crankshaft located within the housing. A fixing plate is fixedly connected to the outer wall of the crankshaft, and a through hole is formed at the top of the fixing plate, through which a copper tube is inserted. This application utilizes the mixing assembly to allow the crankshaft to drive the fixing plate and copper tube to rotate. The contact position between the copper tube and the heating support plate is at the lowest point of the heating support plate's swing. When the contact position between the heating support plate and the copper tube changes, the lowest point of the heating support plate's swing also changes. The heating support plate repeatedly swings circumferentially, causing the material to move and mix on the top of the heating support plate. Furthermore, the heating support plate can dry the material while it is dispersed, greatly improving the drying and mixing effect of the dryer.

[0004] In the vacuum mixing dryer described in the aforementioned patent, although the copper tube can be raised and lowered, the horizontal distance between the copper tube and the motor output end remains unchanged. This results in the copper tube only being able to rotate and stir at the same radial position inside the dryer, leading to poor mixing uniformity of the materials inside the dryer. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum mixing and drying device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum mixing drying device, including a shell, an air pipe and a feed pipe are provided on the top of the outer wall of the shell, a heating bracket is vertically and slidably connected to the bottom of the inner wall of the shell, a guide rod is rotatably connected to the inner wall of the shell above the heating bracket, a support sleeve is slidably fitted on the outer wall of the guide rod, and a stirring rack is provided on one side of the outer wall of the support sleeve.

[0007] Furthermore, the stirring rack includes a horizontally arranged support rod, and a spiral frame is vertically provided on the outer wall of the support rod.

[0008] Furthermore, a servo motor is vertically mounted at the top center of the housing, and a connecting shaft is vertically mounted at the top of the guide rod, with the output shaft of the servo motor fixedly connected to the connecting shaft.

[0009] Furthermore, the top of the guide rod is provided with a first limiting ring, and the bottom of the guide rod is provided with a second limiting ring.

[0010] Furthermore, a servo electric cylinder is vertically installed at the center of the bottom of the heating bracket, and the bottom of the servo electric cylinder is fixedly connected to the bottom of the inner wall of the housing.

[0011] Furthermore, a discharge pipe is provided on one side of the bottom of the outer wall of the housing, and valve assemblies are provided inside both the inlet pipe and the discharge pipe.

[0012] Furthermore, the heating bracket is a circular tray structure, the outer wall of the heating bracket has a through groove that matches the discharge pipe, and the top center of the heating bracket is a spherical shell structure.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model comprises a shell, an air pipe, a feed pipe, a heating bracket, a guide rod, a support sleeve, and a stirring frame. The guide rod guides and supports the support sleeve, which can slide up and down along the guide rod. Because the guide rod is inclined inside the shell, the position of the support sleeve can be horizontally adjusted inside the shell during its up-and-down sliding motion. The support sleeve supports the stirring frame, and the horizontal adjustment of the support sleeve allows for adjustment of the stirring frame's position, thereby enabling the stirring frame to rotate and stir at different radial positions inside the shell, effectively improving the uniformity of material mixing. The heating bracket is adjustable in height, and its lifting motion drives the stirring frame to move up and down. The stirring frame moves along the guide rod with the support sleeve, effectively achieving horizontal adjustment of the stirring frame.

[0015] 2. In this utility model, the support rod in the stirring frame is used to connect and support the support sleeve and the spiral frame, ensuring that the spiral frame moves up and down and is horizontally adjusted with the support sleeve. This allows the spiral frame to be adjusted to different radial positions inside the shell. A vacuum device is used to evacuate the air inside the shell through an air pipe, ensuring that the environment inside the shell is in a vacuum state. The servo motor drives the guide rod to rotate through the connecting shaft. The support rod and the spiral frame rotate with the guide rod. The spiral frame performs spiral contact stirring of the material inside the shell, which can effectively improve the uniformity of the material stirring process, thereby improving the vacuum drying effect of the material.

[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 Figures 1-4 The present invention provides a technical solution: a vacuum mixing drying device, comprising a shell 1, an air pipe 2 and a feed pipe 3 provided on the top of the outer wall of the shell 1, a heating bracket 4 vertically connected to the bottom of the inner wall of the shell 1, a guide rod 5 rotatably connected to the inner wall of the shell 1 above the heating bracket 4, a support sleeve 6 slidably sleeved on the outer wall of the guide rod 5, and a stirring frame 7 provided on one side of the outer wall of the support sleeve 6; the stirring frame 7 includes a horizontally arranged support rod 701, and a spiral frame 702 vertically arranged on the outer wall of the support rod 701.

[0024] In one embodiment, a servo motor 101 is vertically mounted at the top center of the housing 1, and a connecting shaft 501 is vertically mounted at the top of the guide rod 5. The output shaft of the servo motor 101 is fixedly connected to the connecting shaft 501. The servo motor 101 drives the guide rod 5 to rotate through the connecting shaft 501. The guide rod 5 rotates with the connecting shaft 501 and performs a conical motion inside the housing 1. The guide rod 5 drives the support sleeve 6 to move synchronously, and the support sleeve 6 drives the stirring frame 7 to stir the material inside the housing 1.

[0025] In one embodiment, the guide rod 5 is provided with a first limiting ring 502 at the top and a second limiting ring 503 at the bottom. The first limiting ring 502 limits the support sleeve 6 at the top of the guide rod 5, and the second limiting ring 503 limits and supports the support sleeve 6 at the bottom of the guide rod 5. This can effectively limit the lifting range of the stirring rack 7, and thus limit the horizontal range of the stirring rack 7.

[0026] In one embodiment, a servo cylinder 401 is vertically mounted at the bottom center of the heating bracket 4. The bottom of the servo cylinder 401 is fixedly connected to the bottom of the inner wall of the housing 1. The extension and retraction of the servo cylinder 401 drives the heating bracket 4 to rise and fall. The heating bracket 4 abuts against the bottom of the stirring rack 7. As the heating bracket 4 rises and falls, it can drive the stirring rack 7 to rise and fall. The support sleeve 6 moves up and down along the guide rod 5, which can adjust the horizontal position of the stirring rack 7. This enables the stirring rack 7 to rotate and stir at different radial positions inside the housing 1, which can effectively improve the uniformity of material mixing.

[0027] In one embodiment, a discharge pipe 102 is provided on one side of the bottom of the outer wall of the housing 1. Both the feed pipe 3 and the discharge pipe 102 are equipped with valve assemblies. The discharge pipe 102 is used to discharge the material inside the housing 1. The valve assemblies inside the feed pipe 3 and the discharge pipe 102 can effectively seal the feed pipe 3 and the discharge pipe 102 to ensure the vacuum environment inside the housing 1.

[0028] In one embodiment, the heating bracket 4 is a circular tray structure. Designing the heating bracket 4 as a circular tray structure can effectively support and limit the material, while ensuring that the material will not move below the heating bracket 4 when the heating bracket 4 is raised or lowered, thus ensuring the safety of the material and the equipment. The outer wall of the heating bracket 4 is provided with a through groove 402 that matches the discharge pipe 102. The through groove 402 is grooved on the heating bracket 4, which facilitates the material to be transported from the heating bracket 4 to the discharge pipe 102 during discharge. The top center of the heating bracket 4 is a spherical shell structure. The design of the top center of the heating bracket 4 as a spherical shell structure facilitates the dispersion of the material falling on the top of the heating bracket 4 along the spherical shell structure, making it easier to send the material into the discharge pipe 102 through the through groove 402.

[0029] The working principle of this utility model:

[0030] Refer to the instruction manual appendix Figures 1-4 This utility model comprises a shell 1, an air pipe 2, a feed pipe 3, a heating bracket 4, a guide rod 5, a support sleeve 6, and a stirring rack 7. The shell 1 serves as a container for vacuum drying. In use, material is fed into the shell 1 through the feed pipe 3. After the material enters the shell 1, the heating bracket 4 receives the material inside the shell 1. The guide rod 5 guides and supports the support sleeve 6, which can slide up and down along the guide rod 5. Because the guide rod 5 is inclined inside the shell 1, the position of the support sleeve 6 can be adjusted horizontally inside the shell 1 during its up-and-down sliding motion. The support sleeve 6 supports the stirring rack 7, and the horizontal adjustment of the support sleeve 6 allows for adjustment of the position of the stirring rack 7, thereby enabling the stirring rack 7 to rotate and stir at different radial positions inside the shell 1, effectively improving the uniformity of material mixing. The heating bracket 5 is adjustable in height. When the heating bracket 4 moves up and down, it drives the stirring rack 7 to move up and down. The stirring rack 7 moves along the guide rod 5 with the support sleeve 6, effectively achieving horizontal adjustment of the stirring rack 7.

[0031] The support rod 701 in the mixing rack 7 is used to connect and support the support sleeve 6 and the spiral frame 702, ensuring that the spiral frame 702 moves up and down and is horizontally adjusted with the support sleeve 6. This allows the spiral frame 702 to be adjusted to different radial positions inside the shell 1. A vacuum pump is used to evacuate the air inside the shell 1 through the air pipe 2, ensuring that the environment inside the shell 1 is in a vacuum state. The servo motor 101 drives the guide rod 5 to rotate through the connecting shaft 501. The guide rod 5 moves in a conical motion inside the shell 1. The support rod 701 and the spiral frame 702 rotate with the guide rod 5. The spiral frame 702 performs spiral contact mixing treatment on the material inside the shell 1, which can effectively improve the uniformity of material mixing treatment, thereby improving the vacuum drying effect of the material.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
