[0021] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figures 1 to 6 The utility model provides a low-temperature spray dryer, including a dryer body 1, a bottom plate 25 fixedly connected to the bottom of the dryer body 1, and a control cabinet 2 fixedly connected to the side wall of the dryer body 1. A support plate 5 is provided in the bottom plate 25 so as to be drawable. A limiting groove 6 is provided on the support plate 5. A clamping plate 20 is circumferentially provided in the limiting groove 6. A rubber pad is fixedly connected to the inner wall of the clamping plate 20. One end of the clamping plate 20 is rotatably connected to the limiting groove 6, and a spring 21 is fixedly connected between the other end and the inner wall of the limiting groove 6. Specifically, the support plate 5 is pulled out of the bottom plate 25, the container containing the liquid material is placed in the limiting groove 6, and the clamping plate 20 is squeezed by the bottom of the container to make the clamping plate 20 rotate counterclockwise, open outward and squeeze the spring three 21, so that the container is placed in the middle of the clamping plate 20. Under the action of the restoring force of the spring three 21, the clamping plate 20 is pressed against the outer wall of the container to fix the container. Compared with the existing low-temperature spray dryer, when using it, the container can only be placed directly on the ground or on the edge of the bottom plate 25. The utility model can place the container more stably through the setting of the support plate 5, and it is not easy to overturn.

[0023] Furthermore, if Figure 1 , Figure 6 As shown, a groove 24 is provided at the top corner of the support plate 5, a spring 23 is fixedly connected in the groove 24, a pull rod 22 is fixedly connected to the bottom end of the spring 23, a slide groove 8 is provided on the side wall of the bottom plate 25, and the end of the pull rod 22 away from the spring 23 passes through the slide groove 8 and is fixedly connected to the handle 7, and both ends of the slide groove 8 are provided with a 90-degree downward corner. Specifically, under the action of the spring 23, the pull rod 22 is pressed downward in the corner, and when it is necessary to pull out the support plate 5, the pull rod 22 is lifted upward by the handle 7, so that the pull rod 22 enters the straight section of the slide groove 8, and at this time, the pull rod 22 can move to the right side of the slide groove 8. When the pull rod 22 moves to the rightmost end of the slide groove 8, the handle 7 is released, and under the action of the spring 23, the pull rod 22 enters the corner at the right end of the slide groove 8, which plays a role in limiting the support plate 5 and preventing the support plate 5 from shaking left and right.

[0024] Furthermore, if Figure 1 , Figure 2As shown, the control cabinet 2 is connected to a liquid inlet pipe 3, and a receiver 4 matching the liquid inlet pipe 3 is fixedly connected to the side wall of the control cabinet 2. The receiver 4 includes a mounting plate 9 fixedly connected to the side wall of the control cabinet 2, a pipe clamp 12 slidably placed on the mounting plate 9, and a positioning clamp 10 fixedly connected to the top of the mounting plate 9. Two pipe clamps 12 are symmetrically arranged, and the pipe clamps 12 are U-shaped, and elastic pieces 13 are symmetrically fixedly connected to the inner sides of the pipe clamps 12. Specifically, the liquid inlet pipe 3 can be wound around the pipe clamps 12 through the two U-shaped pipe clamps 12 symmetrically arranged up and down. The elastic piece 13 is arc-shaped, made of rubber material, and has elasticity, which can better wrap and squeeze the liquid inlet pipe 3, so that the liquid inlet pipe 3 is wound more stably and not easy to loosen. Finally, the end of the liquid inlet pipe 3 is fixed by the positioning clamp 10.

[0025] Furthermore, if Figure 2 As shown, one side of the pipe clamp 12 is fixed to the slider 11, a convex groove is formed on the mounting plate 9, and positioning holes are formed in the convex groove at equal intervals, the slider 11 is slidably placed in the convex groove, and the slider 11 is threadedly connected with a positioning bolt, and a knob is fixed to the end of the positioning bolt. Specifically, the shape of the slider 11 matches the convex groove and is convex, and can be stuck in the convex groove. After the position of the slider 11 is determined, the positioning bolt is rotated by the knob so that the positioning bolt is screwed into the positioning hole, thereby fixing the position of the slider 11. By setting the slider 11, the position of the pipe clamp 12 is adjustable, so that the distance between the two pipe clamps 12 can be flexibly adjusted according to the length of the liquid inlet pipe 3.

[0026] Furthermore, if Figure 3 , Figure 4 As shown, the positioning clamp 10 includes a fixed ring 14 fixed to the mounting plate 9, an elastic band 15 fixed to the inner side of the fixed ring 14, and a movable ring 16 slidably placed on the inner side of the fixed ring 14. A partition 19 is provided in the fixed ring 14, and a spring 2 18 is fixed to one side of the partition 19. The end of the spring 2 18 away from the partition 19 is fixed to the movable ring 16, and a spring 17 is fixed between the elastic band 15 and the inner wall of the fixed ring 14. Specifically, when the positioning clamp 10 is in use, the movable ring 16 is bent to one side so that one end of the movable ring 16 is further extended into the inner side of the fixed ring 14, and the spring 18 is squeezed. An opening is formed on one side of the movable ring 16, and the liquid inlet tube 3 is placed into the inner side of the movable ring 16 through the opening. Then the movable ring 16 is loosened to reset and close the movable ring 16. The liquid inlet tube 3 is clamped by the elastic band 15 and the movable ring 16, and the spring 17 is supported on the outside of the elastic band 15 to increase the clamping force. At the same time, the elasticity of the elastic band 15 is used to prevent the liquid inlet tube 3 from being damaged.

[0027] Working principle: when the liquid inlet tube 3 is not in use, the liquid inlet tube 3 is wound around the tube clamp 12, and the liquid inlet tube 3 is clamped by the spring sheet 13 to prevent the liquid inlet tube 3 from being loose. Finally, the end of the liquid inlet tube 3 is fixed by the positioning clamp 10. When the positioning clamp 10 is in use, the movable ring 16 is opened to one side to put the liquid inlet tube 3 in, and then the elastic band 15 and the movable ring 16 are used to clamp and fix the liquid inlet tube 3, so that the liquid inlet tube 3 is stored in the storage container 4.

[0028] When a liquid container needs to be placed, the pull rod 22 is lifted upward by the grip 7 and then pulled to the right to pull the support plate 5 out of the bottom plate 25, and the container is placed in the middle of the clamping plate 20. Under the action of the spring three 21, the clamping plate 20 is pressed against the outer wall of the container to fix the container.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
