Description

Technical Field

[0001] This application relates to pellet mill technology, and more particularly to a pellet mill feeding device. Background Technology

[0002] In the production of traditional Chinese medicine drop pills, drop pill machines are typically used to process the drop pills. Existing drop pill machines are usually equipped with a feeding device to provide a uniformly mixed medicinal solution at a specific temperature.

[0003] Currently, a common feeding device for pellet mills includes a heating tank. The heating tank has a feeding port at the top, a stirring mechanism inside, and a liquid outlet pipe at the bottom. A liquid pump is mounted on the outlet pipe, which connects to the pellet mill's inlet. In use, the medicinal liquid and matrix are fed into the heating tank through the feeding port. The stirring mechanism mixes the medicinal liquid and matrix to form a mixture, while the heating tank heats the mixture. The mixture is then directly delivered to the pellet mill via the liquid pump and outlet pipe.

[0004] However, in actual use, when the drug solution and matrix are mixed by the stirring mechanism alone, a long stirring time is required to ensure that the drug solution and matrix are fully mixed. Moreover, some batches of drug solution or matrix may contain impurities. When the mixed drug solution is directly transported to the pelleting machine for pelleting after mixing, these impurities will enter the pelleting machine with the mixed drug solution and eventually remain in the pellet preparation, affecting the quality of the pellet preparation. Utility Model Content

[0005] This application provides a feeding device for a pellet mill, which solves the problems of long time consumption, low efficiency, and impurities in the mixed medicine solution when the feeding device used in the existing pellet mill is used to stir and mix the medicine solution and matrix.

[0006] This application provides a feeding device for a pellet mill, including a heating tank, a feeding port at the top of the heating tank, a rotatable stirring structure inside the heating tank, and a liquid pump connected to the bottom of the heating tank;

[0007] The upper part of the heating tank is equipped with a filter cylinder;

[0008] The liquid pump is connected to valve I, and a delivery pipe is connected between the liquid pump and valve I. Valve II is installed on the delivery pipe, and the delivery pipe extends above the filter cylinder.

[0009] Optionally, the top of the heating tank is provided with a loading port located directly below the filter cylinder, and a detachable sealing cover is fixed to the upper end of the loading port. The sealing cover is fixedly connected to the filter cylinder through a connector.

[0010] Optionally, the connector is a spring or an elastic rubber rod;

[0011] The stirring structure is fixed with a pusher, which can push the filter cylinder to move after the stirring structure rotates.

[0012] Optionally, the number of pushers is two, and the two pushers are symmetrically distributed about the rotation center of the stirring structure.

[0013] Optionally, the heating tank includes an insulated box, the interior of which is a tank body with a gap between itself and its inner wall, the gap being filled with heat transfer oil, and the gap being connected to a heat transfer oil circulation device capable of heating the heat transfer oil.

[0014] Optionally, the delivery pipe extends into the gap and extends from the gap above the filter cartridge.

[0015] Optionally, the lower end of the insulated box is provided with an insulated sleeve, and the liquid pump, valve I and valve II are all located inside the insulated sleeve.

[0016] Optionally, the insulation sleeve has a ring structure, the outer wall of the insulation sleeve is provided with an insulation layer, the ring wall of the insulation sleeve has a hollow structure, and the ring wall of the insulation sleeve is in communication with the gap.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] The pellet mill feeding device provided in this application has a feeding port at the top of a heating tank. The heating tank contains a rotatable stirring structure, and a liquid pump is connected to the bottom. A filter cylinder is located in the upper part of the heating tank. The liquid pump is connected to valve I, and a conveying pipe connects the liquid pump and valve I. Valve II is installed on the conveying pipe, which extends above the filter cylinder. During use, when the liquid medicine and matrix are added to the heating tank, the stirring structure rotates and mixes the liquid medicine and matrix to form a mixed liquid medicine. The heating tank heats the mixed liquid medicine. Simultaneously, valve I is closed, valve II is opened, and the liquid pump is started to draw out the liquid. The pump draws the mixed liquid from the bottom of the heating tank into the delivery pipe, which then transports it to the filter cartridge. The filter cartridge filters out impurities from the mixed liquid, which then flows back into the heating tank. Simultaneously, the stirring structure agitates the mixed liquid and matrix, allowing the initially mixed liquid to circulate within the heating tank, improving mixing efficiency and shortening mixing time. Furthermore, the filter cartridge filters out impurities from the mixed liquid during circulation, preventing them from entering the pelleting machine and remaining in the pellet preparation, thus affecting its quality.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0026] like Figures 1-3 As shown:

[0027] An embodiment of this application provides a feeding device for a pellet mill, including a heating tank 1. The top of the heating tank 1 is provided with a feeding port 2, and the interior of the heating tank 1 is provided with a rotatable stirring structure 3. Specifically, the stirring structure 3 includes a rotating shaft 301, on which a plurality of vertically distributed stirring blade assemblies 302 are fixed. The top of the heating tank 1 is fixed with a motor 303, and the output shaft of the motor 303 is fixedly connected to the rotating structure.

[0028] A liquid pump 4 is connected to the bottom of the heating tank 1.

[0029] A filter cylinder 5 is provided in the upper part of the heating tank 1. Specifically, the filter cylinder 5 is a hollow structure with an open top, and the bottom and sides of the filter cylinder 5 are made of filter screen.

[0030] The liquid pump 4 is connected to valve I6, and a delivery pipe 7 is connected between the liquid pump 4 and valve I6. Valve II8 is installed on the delivery pipe 7, and the delivery pipe 7 extends above the filter cylinder 5.

[0031] In this embodiment, the heating tank 1 is located at the upper end of the pellet mill 16, and valve I6 is connected to the feed inlet of the pellet mill 16. Both valve I6 and valve II8 are electric valves.

[0032] In use, add the medicine and matrix into the heating tank 1 through the feeding port 2, start the motor 303, the motor 303 drives the rotating shaft 301 to rotate, and the rotation drives all the stirring blade assembly 302 to rotate synchronously, stirring and mixing the medicine and matrix to form a mixed medicine. The heating tank 1 heats the mixed medicine, while closing valve I6 and opening valve II8, starting the liquid pump 4. The liquid pump 4 draws the mixed medicine from the bottom of the heating tank 1 into the conveying pipe 7. The conveying pipe 7 transports the mixed medicine into the filter cylinder 5. The filter cylinder 5 filters the impurities in the mixed medicine. The filtered mixed medicine flows back into the heating tank 1 to mix with the mixed medicine in the heating tank 1. After the medicine and matrix are mixed, close valve II8 and open valve I6. The liquid pump 4 transports the mixed medicine into the pelleting machine 16 for pelleting.

[0033] The feeding device for the pellet mill provided in this embodiment has a feeding port 2 at the top of the heating tank 1, a rotatable stirring structure 3 inside the heating tank 1, a liquid pump 4 connected to the bottom of the heating tank 1, a filter cylinder 5 in the upper part of the heating tank 1, a valve I 6 connected to the liquid pump 4, a conveying pipe 7 connected between the liquid pump 4 and the valve I 6, a valve II 8 on the conveying pipe 7, and the conveying pipe 7 extends above the filter cylinder 5. This allows the mixing liquid and matrix to circulate up and down in the heating tank 1 while the stirring structure 3 is stirring, thereby improving mixing efficiency and shortening mixing time. Moreover, while the mixed liquid is circulating, the filter cylinder 5 can filter impurities in the mixed liquid, preventing impurities from entering the pellet mill 16 with the mixed liquid and ultimately remaining in the pellet preparation, thus affecting the quality of the pellet preparation.

[0034] In some embodiments of this application, the top of the heating tank 1 is provided with a loading / unloading port 9 located directly below the filter cylinder 5, and a removable sealing cap 10 is fixed to the upper end of the loading / unloading port 9. Specifically, the sealing cap 10 and the loading / unloading port 9 are detachably fixedly connected by bolts. The sealing cap 10 is fixedly connected to the filter cylinder 5 by a connector 11. Specifically, one end of the connector 11 is fixedly connected to the lower end of the sealing cap 10, and the other end of the connector 11 is detachably fixedly connected to the inner bottom of the filter cylinder 5, facilitating the replacement of the filter cylinder 5 later.

[0035] In use, simply remove the sealing cover 10 and then move the sealing cover 10 upwards to pull the filter cartridge 5 out of the heating tank 1, which makes it easier for staff to clean the impurities inside the filter cartridge 5.

[0036] In some embodiments of this application, the connector 11 is a spring or an elastic rubber rod.

[0037] The stirring structure 3 is fixed with a pusher 12, which can push the filter cylinder 5 to move after the stirring structure 3 rotates. Specifically, the pusher 12 is fixed on the rotating shaft 301 and is located on the side of the filter cylinder 5.

[0038] In this embodiment, the connector 11 is an elastic rubber rod.

[0039] In use, when the pusher 12 rotates with the rotating shaft 301, after the pusher 12 contacts the filter cylinder 5, the pusher 12 pushes the filter cylinder 5 to move while rotating. After the filter cylinder 5 moves, the connecting member 11 deforms. When the pusher 12 separates from the filter cylinder 5, the connecting member 11 returns to its original state and drives the filter cylinder 5 to reset. When the pusher 12 rotates continuously, it can intermittently push the filter cylinder 5 to move. Thus, under the action of the connecting member 11, the filter cylinder 5 can generate vibration when filtering impurities in the mixed medicine solution to improve the filtration efficiency.

[0040] In some embodiments of this application, there are two pushers 12, which are symmetrically distributed about the rotation center of the stirring structure 3, in order to increase the vibration frequency of the filter cylinder 5 and thus improve the vibration effect of the filter cylinder 5.

[0041] In some embodiments of this application, the heating tank 1 includes an insulation box 101, and the interior of the insulation box 101 is provided with a tank body 102 with a gap 103 between it and its inner wall. The gap 103 is filled with heat transfer oil, and the gap 103 is connected to a heat transfer oil circulation device (not shown in the figure) that can heat the heat transfer oil.

[0042] In this embodiment, both the stirring structure 3 and the filter cylinder 5 are located inside the tank 102, and the liquid pump 4 is connected to the bottom of the tank 102. The heat transfer oil circulation device is prior art and will not be described in detail.

[0043] During use, the heat transfer oil circulates within the gap 103 to heat the mixed medicine solution inside the tank 102.

[0044] In some embodiments of this application, the delivery pipe 7 extends into the gap 103 and extends from the gap 103 to above the filter cylinder 5, so that when the mixed medicine flows in the delivery pipe 7, the heat-conducting oil in the gap 103 can heat the flowing mixed medicine, thereby improving the heating efficiency of the mixed medicine.

[0045] In some embodiments of this application, the lower end of the insulated box 101 is provided with an insulated sleeve 13, and the liquid pump 4, valve I6 and valve II8 are all located inside the insulated sleeve 13 to reduce the amount of heat loss of the mixed medicine solution when passing through valve I6 or valve II8.

[0046] In some embodiments of this application, the insulation sleeve 13 has an annular structure, the outer wall of the insulation sleeve 13 is provided with an insulation layer, the annular wall 1301 of the insulation sleeve 13 has a hollow structure, and the annular wall 1301 of the insulation sleeve 13 is connected to the gap 103.

[0047] In this embodiment, the upper part of the gap 103 is connected to the oil outlet of the heat transfer oil circulation device through the oil inlet pipe 14, and the lower part of the annular wall 1301 is connected to the oil inlet of the heat transfer oil circulation device through the oil outlet pipe 15, so that the heat transfer oil can circulate inside the gap 103 and the annular wall 1301, thereby improving the heat insulation effect of the insulation jacket 13.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
