Description

Technical Field

[0001] This application relates to the field of vacuum dryer technology, and in particular to a rake-type vacuum dryer discharge structure. Background Technology

[0002] Rake dryers are widely used in the chemical, food, and pharmaceutical industries. They are particularly suitable for drying paste-like materials that are not heat-resistant, flammable, or easily oxidized at high temperatures. They are simple in structure and easy to operate. They use a rotating main shaft to drive rake teeth to evenly distribute the material inside the cylinder on the cylinder wall. By heating the material on the inner cylinder wall, the moisture in the material evaporates, thereby achieving the purpose of drying the material.

[0003] A vacuum dryer is a device that removes moisture from a packaging container by drawing air out of the container to achieve a predetermined vacuum level. The processed material needs to be discharged. However, the existing discharge ports have poor discharge efficiency and are not easy to observe. Therefore, this application proposes a rake-type vacuum dryer discharge structure to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rake-type vacuum dryer discharge structure, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rake-type vacuum dryer discharge structure, comprising a cylinder, a material cylinder fixedly connected to the outer side of the cylinder, a discharge port fixedly connected to the bottom of the material cylinder, a side discharge port fixedly connected to the outer side of the material cylinder, a side plate fixedly installed on the side of the material cylinder away from the material cylinder, a connecting plate fixedly installed on the outer side of the side plate by a plurality of bolts, a fixing pipe fixedly installed on the outer side of the connecting plate, an outer ring of a bearing fixedly connected to the inner wall of the fixing pipe, a threaded shaft fixedly connected to the inner ring of the bearing, a moving block slidably connected to the outer edge of the threaded shaft, a nut threadedly connected to the outer edge of the threaded shaft, an extension pipe fixedly installed on the side of the moving block away from the nut, and a pusher plate fixedly connected to the side of the extension pipe away from the moving block.

[0006] In a preferred embodiment, the inner wall of the side outlet is threaded with a transparent window, and multiple protrusions are fixedly installed on the outer edge of the transparent window.

[0007] By adopting the above technical solution, the inner cavity of the discharge port on the opposite side can be sealed, and the state of the inner cavity of the barrel can be observed from the outside through the transparent window. The protrusions also improve the convenience for users when rotating the transparent window.

[0008] In a preferred embodiment, a rocker wheel is fixedly connected to one outer end of the threaded shaft.

[0009] By adopting the above technical solution, the user's convenience when rotating the threaded shaft is increased, making it easier to apply force with the hand.

[0010] In a preferred embodiment, the nut is fixedly connected to the movable block, the inner wall of the fixed tube is symmetrically provided with limit grooves, and two limit blocks are symmetrically fixedly installed on the outer edge of the movable block, and the two limit blocks are slidably connected to the inner wall of the limit groove.

[0011] By adopting the above technical solution, the rotation of the threaded shaft can be achieved by using the nut to drive the moving block to slide on the inner wall of the fixed pipe. In turn, the limiting block and the limiting groove can be used to ensure that the moving block will not rotate along with the force of the threaded shaft rotation.

[0012] In a preferred embodiment, the inner walls of the side plate and the connecting plate are provided with through holes, and the extension tube is adapted to slide and connect to the inner wall of the through holes.

[0013] By adopting the above technical solution, when the moving block slides on the inner wall of the fixed tube, it can drive the extension tube to slide on the inner wall of the through hole, thereby driving the extension tube to move.

[0014] In a preferred embodiment, the pusher is slidably connected to the inner wall of the cylinder, and a discharge port is provided on the outer side of the cylinder. The pusher is fitted and disposed at the corresponding position of the discharge port on the outer side of the cylinder for sealing.

[0015] By adopting the above technical solution, after the pusher moves away from the discharge port, the material in the inner cavity of the cylinder can enter the inner cavity of the cylinder through the discharge port. At the same time, the pusher can move again to rake the material to the inner wall of the discharge port and discharge it to the outside.

[0016] The beneficial effects of this application are:

[0017] 1. The discharge structure of this rake-type vacuum dryer can be used to seal the discharge port on the outside of the cylinder by setting a pusher plate. After the pusher plate moves away from the discharge port, the material in the inner cavity of the cylinder can enter the inner cavity of the cylinder through the discharge port. At the same time, the pusher plate can be used to move again to rake the material to the inner wall of the discharge port and discharge it to the outside, which improves the speed of material discharge.

[0018] 2. The discharge structure of this rake-type vacuum dryer can be used to seal the inner cavity of the discharge port on the opposite side by setting a transparent window, and the state of the inner cavity of the material cylinder can be observed from the outside through the transparent window, thus improving the visualization effect.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Reference Figure 1-4 A rake-type vacuum dryer discharge structure includes a cylinder 1, a material cylinder 2 fixedly connected to the outside of the cylinder 1, a discharge port 3 fixedly connected to the bottom of the material cylinder 2, a side discharge port 4 fixedly connected to the outside of the material cylinder 2, a side plate 6 fixedly installed on the side of the material cylinder 2 away from the material cylinder 2, a connecting plate 7 fixedly installed on the outside of the side plate 6 by several bolts 16, a fixing pipe 8 fixedly installed on the outside of the connecting plate 7, an outer ring of a bearing 9 fixedly connected to the inner wall of the fixing pipe 8, a threaded shaft 10 fixedly connected to the inner ring of the bearing 9, a moving block 12 slidably connected to the outer edge of the threaded shaft 10, a nut 13 threadedly connected to the outer edge of the threaded shaft 10, an extension pipe 14 fixedly installed on the side of the moving block 12 away from the nut 13, and a push plate 15 fixedly connected to the side of the extension pipe 14 away from the moving block 12.

[0026] See Figure 2 and Figure 3 A transparent window 5 is threadedly connected to the inner wall of the side outlet 4. Multiple protrusions are fixedly installed on the outer edge of the transparent window 5, which can be used to seal the inner cavity of the side outlet 4. The state of the inner cavity of the material cylinder 2 can be observed from the outside through the transparent window 5, and the protrusions improve the convenience for the user when rotating the transparent window 5.

[0027] See Figure 1 - Figure 4 A rocker wheel 11 is fixedly connected to one end of the outer side of the threaded shaft 10, which increases the convenience for the user to rotate the threaded shaft 10 and makes it easier to exert force with the hand.

[0028] See Figure 4Nut 13 is fixedly connected to movable block 12. The inner wall of fixed tube 8 is symmetrically provided with limit grooves. Two limit blocks are symmetrically fixedly installed on the outer edge of movable block 12, and the two limit blocks are slidably connected to the inner wall of the limit groove. This allows the movable block 12 to slide on the inner wall of fixed tube 8 when the threaded shaft 10 rotates, using nut 13. In this way, the limit blocks and limit grooves can be used to ensure that the movable block 12 will not rotate along with the force of the threaded shaft 10 when it rotates.

[0029] See Figure 2 The inner walls of the side plate 6 and the connecting plate 7 are provided with through holes. The extension tube 14 is adapted to slide and connect to the inner wall of the through hole, so that when the moving block 12 slides on the inner wall of the fixed tube 8, it can drive the extension tube 14 to slide on the inner wall of the through hole, thereby driving the extension tube 14 to move.

[0030] See Figure 3 and Figure 4 The pusher plate 15 is slidably connected to the inner wall of the cylinder 2. A discharge port is provided on the outer side of the cylinder 1. The pusher plate 15 is fitted to the corresponding position of the discharge port on the outer side of the cylinder 1 for sealing. After the pusher plate 15 moves away from the discharge port, the material in the inner cavity of the cylinder 1 can enter the inner cavity of the cylinder 2 through the discharge port. At the same time, the pusher plate 15 can be moved again to rake the material to the inner wall of the discharge port 3 and discharge it to the outside.

[0031] Working principle: When using this device, the transparent window 5 is first used to seal the inner cavity of the side discharge port 4. The state of the inner cavity of the material cylinder 2 can be observed from the outside through the transparent window 5, which improves the visualization effect. The protrusion improves the convenience of the user when rotating the transparent window 5. At the same time, the push plate 15 can be used to seal the discharge port on the outside of the cylinder 1. The rocker wheel 11 can be rotated to drive the threaded shaft 10 to rotate, which can drive the moving block 12 to slide on the inner wall of the fixed tube 8. This can be used to drag the extension tube 14 to slide on the inner wall of the side plate 6 and the connecting plate 7. After the push plate 15 moves away from the discharge port, the material in the inner cavity of the cylinder 1 can enter the inner cavity of the material cylinder 2 through the discharge port. At the same time, the push plate 15 can be moved again to rake the material to the inner wall of the discharge port 3 and discharge it to the outside.
