[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort also belong to the protection scope of the present application.
[0021] As Figures 1-5 shown in the figure, the embodiment provides a pill drying device, which comprises a drying box 1, a boiling bed 2 arranged in the drying box 1, an inlet pipe 3 at one end of the boiling bed 2, and an outlet pipe 4 connected to the other end of the boiling bed 2. A partition plate 5 is arranged above the boiling bed 2 and is fixedly sealed to the drying box 1. The partition plate 5 is provided with through holes for ventilation and dust entering. A plurality of dust removal cloth bags 6 are fixed to the partition plate 5. The openings of the plurality of dust removal cloth bags 6 are downwardly directed and correspond to the positions of the through holes and are arranged in a straight line. A dust collecting groove 7 is fixedly arranged below the openings of the dust removal cloth bags 6 and is arranged along the arrangement direction of the dust removal cloth bags 6. The dust collecting groove 7 is arranged in an inclined manner and one end thereof penetrates through the side wall of the drying box 1 and is provided with a sealingly connected cover 8.
[0022] When the pill is dried, the pill enters the boiling bed 2 from the inlet pipe 3. At the same time, dry hot air is blown upwardly from the bottom of the boiling bed 2 and widely contacts the pill on the boiling bed 2. The water vapor and dust particles after drying are carried upwardly by the hot air, enter the dust removal cloth bags 6 through the through holes in the partition plate 5 from both sides of the dust collecting groove 7, and are filtered by the dust removal cloth bags 6. The intercepted dust particles and water vapor are mixed and gathered, adhere to the inner wall of the dust removal cloth bags 6 to form a hardened block, and the dust particles of the hardened block fall downwardly through the openings of the dust removal cloth bags 6 and fall into the dust collecting groove 7. The cover 8 is opened to clean the dust particles accumulated in the dust collecting groove 7.
[0023] In the embodiment, the hot air used for drying the pill upwardly penetrates through the boiling bed 2, carries the water vapor and dust particles upwardly, bypasses the dust collecting groove 7, and enters the dust removal cloth bags 6 for filtering. The dust particles adhered to the inner wall of the dust removal cloth bags 6 fall downwardly and fall into the dust collecting groove 7 through the openings, thereby avoiding falling back to the boiling bed 2 and improving the quality of the pill. The dust particles collected in the dust collecting groove 7 are cleaned by opening the cover 8.
[0024] In a possible implementation manner, one end of the dust collecting groove 7 arranged in an inclined manner upwardly is provided with an air inlet pipe 9, the air inlet pipe 9 penetrates through the side wall of the drying box 1 and is fixed, and a valve is arranged on the air inlet pipe 9. One end of the air inlet pipe 9 arranged in the drying box 1 can blow air along the bottom wall inside the dust collecting groove 7, and the other end is in communication with an air compressor.
[0025] When the dust particles accumulated in the dust collecting groove 7 are cleaned, the cover 8 is opened, the air inlet pipe 9 is opened, and air is blown along the bottom wall inside the dust collecting groove 7 to the cover 8, so that the dust particles in the dust collecting groove 7 are blown out from the cover 8.
[0026] In a possible implementation manner, the dust collecting groove 7 is in an arc-shaped and circular tube shape, a spiral blade 10 is arranged inside the dust collecting groove 7, and one end of the dust collecting groove 7 arranged in an inclined manner upwardly is provided with a motor 11 for driving the spiral blade 10.
[0027] When the dust particles accumulated in the dust collecting groove 7 are cleaned, the motor 11 is started to drive the helical blade 10 to rotate, and the dust particles in the dust collecting groove 7 can be pushed out by the helical blade 10.
[0028] In a possible implementation, an upper portion of the partition plate 5 is provided with a movable pressing plate 12, the pressing plate 12 is hoisted with the top surface in the drying box 1 through a vertically fixed telescopic push rod 13, the dust collecting bag 6 is fixed between the partition plate 5 and the pressing plate 12, and a spring 14 for supporting is arranged between the partition plate 5 and the pressing plate 12 and is sleeved on the dust collecting bag 6.
[0029] The telescopic push rod 13 pushes the pressing plate 12 vertically downward, and the dust collecting bag 6 can be compressed downward, and after the telescopic push rod 13 is released, the compressed dust collecting bag 6 can be lifted upward through the spring 14. The reciprocating operation can make the dust collecting bag 6 shake and clean the dust particles adhered to the inner wall thereof, and the shaken dust particles fall into the dust collecting groove 7 through the lower opening.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
