Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of dry granulating machines, and particularly relates to a dry granulation production line. Background Art
[0002] During the roller pressing process of materials by a dry granulating machine, materials will fall from both sides of the roller. Usually, the fallen materials will fall into the sizing screen of the dry granulating machine or directly into the inlet position of the screening machine. During the dry granulation process, blocking and rupture of the sizing screen and rupture or incomplete screening of the screening machine screen are common problems. In particular, materials with characteristics such as heat sensitivity, oiliness, high viscosity, and electrostatic adsorption are difficult problems in dry granulation. The above-mentioned characteristic materials are prone to blocking the screen during the sizing process, resulting in screen rupture. And the screen of the screening machine is prone to blocking, resulting in incomplete screening of the screening machine (there are still fine powders among the qualified particles of the screening machine). Summary of the Invention
[0003] Aiming at the problems existing in the prior art, the present invention provides a dry granulation production line with reasonable structure.
[0004] The technical solution of the present invention is as follows:
[0005] A dry granulation production line, characterized in that it includes a feeding machine, a dry granulating machine and a screening machine. The dry granulating machine includes a roller pressing mechanism, a sizing mechanism and a front cover door. A diversion plate is provided at a position below the roller pressing mechanism on the front cover door. A diversion channel is formed between the diversion plate and the side wall of the front cover door, and the diversion channel is located at a position on one side of the sizing mechanism. A diversion outlet is provided at the lower part of the front cover door at the end of the diversion channel. A fine powder channel is provided on the diversion outlet and is directly connected to the fine powder discharge port of the screening machine through the fine powder channel, and then is introduced into the collection bin through the fine powder discharge port.
[0006] The described dry granulation production line is characterized in that an outlet is further provided on the front cover door, and a particle channel is provided on the outlet and is connected to the top inlet of the screening machine through the particle channel.
[0007] The described dry granulation production line is characterized in that the diversion plate includes an upper receiving plate, a connecting plate and a lower receiving plate. One end of the connecting plate is connected to the upper receiving plate, and the other end is connected to the lower receiving plate, and a group of hooks are provided on the connecting plate.
[0008] The described dry granulation production line is characterized in that a group of support rods are provided on the inner side of the panel of the front cover door, and the diversion plate is hung and installed on the support rods through hooks.
[0009] The described dry granulation production line is characterized in that a straight pipe fitting is provided at the fine powder discharge port. The straight pipe fitting includes a hollow pipe fitting and upper and lower pipe orifices provided at both ends of the hollow pipe fitting. A sieve mesh is provided on the hollow pipe fitting at a position between the fine powder discharge port and the upper pipe orifice.
[0010] The described dry granulation production line is characterized in that the top edge of the upper receiving plate of the diversion plate is located inside the right edge of the pressure wheel of the pressure roller mechanism.
[0011] The beneficial effect of the present invention is that through the designed diversion channel, the fine powder falling at the position of the pressure roller directly enters the fine powder discharge port of the screening machine from the special fine powder channel, thus reducing the working load of the sizing screen of the dry granulator and at the same time reducing the working load of the screening mesh of the screening machine, thereby solving the industry problem.

[0020] The dry granulation production line mainly includes a feeding machine 1, a dry granulator 2 and a screening machine 6; the feeding machine 1 feeds materials by using a vacuum feeding machine or a lifting feeding machine; the dry granulator 2 and the screening machine 6 adopt a dry granulator with single-stage sizing and a double-layer sieve mesh screening machine, a dry granulator with multi-stage sizing and a double-layer sieve mesh screening machine, a dry granulator with single-stage sizing and a single-layer sieve mesh screening machine, or a dry granulator with multi-stage sizing and a single-layer sieve mesh screening machine.
[0021] In this embodiment, the dry granulator 2 includes a pressing roller mechanism 9, a sizing mechanism 8 and a front cover door 14. A deflector 10 is provided on the front cover door 14 at a position below the pressing roller mechanism 9. A diversion channel 11 is formed between the deflector 10 and the side wall of the front cover door 14, and the diversion channel 11 is located at a position on one side of the sizing mechanism 8, so that the materials falling from both sides of the pressing roller can be isolated from the normal pressing roller tablet materials; a diversion outlet 12 is provided at the lower part of the front cover door 14 at the end position of the diversion channel 11. A fine powder channel 3 is provided on the diversion outlet 12 and is directly communicated with the fine powder discharge port 4 of the screening machine 6 through the fine powder channel 3, and then enters the collection bin 5 through the fine powder discharge port 4.
[0022] In this embodiment, a straight pipe fitting 41 is provided on the fine powder discharge port 4. The straight pipe fitting 41 includes a hollow pipe fitting 4101 and upper and lower pipe orifices 4103 and 4104 provided at both ends of the hollow pipe fitting 4101. A sieve mesh 4102 is provided on the hollow pipe fitting 4101 at a position between the fine powder discharge port 4 and the upper pipe orifice 4103 (the installation structure of the sieve mesh 4102 is similar to the installation of the tea filter in a teacup); in this way, large particles or sheet materials coming down from the fine powder channel 3 can be screened and filtered, and the large particles or sheet materials can be manually collected.
[0023] In this embodiment, a discharge port 13 is further provided on the front cover door 14. A particle channel 7 is provided on the discharge port 13 and is communicated with the top inlet of the screening machine 6 through the particle channel 7, and the materials of normal pressing enter the screening machine 6 directly from the discharge port 13.
[0024] In this embodiment, the deflector 10 includes an upper receiving plate 1001, a connecting plate 1002 and a lower receiving plate 1003. One end of the connecting plate 1002 is connected to the upper receiving plate 1001, and the other end is connected to the lower receiving plate 1003. A set of hooks 15 are provided on the connecting plate 1002. At the same time, a set of support rods 16 are provided on the inner side of the panel of the front cover door 14. The deflector 10 is hung and installed on the support rods 16 through the hooks 15. The deflector 10 can isolate materials in different positions, so that the materials are discharged separately from the discharge port 13 and the diversion outlet 12.
[0025] In this embodiment, the top edge of the upper receiving plate 1001 of the deflector 10 is located inside the right edge of the pressing wheel of the pressing roller mechanism 9. The purpose of this setting is to prevent the materials for normal tablet pressing from entering the diversion channel 11.
[0026] Compared with the traditional dry granulation system, this invention adds a fine powder channel 3. The fine powder falling from the position of the pressing roller mechanism 9 does not pass through the granulating mechanism 8 and the screen of the screening machine. Thereby reducing the working load of the granulating screen of the dry granulator and at the same time reducing the working load of the screen of the screening machine. It solves the dry granulation problems of special materials (materials with characteristics such as heat sensitivity, oiliness, high viscosity, electrostatic adsorption, etc.).
