Description

Technical Field

[0001] The invention belongs to the technical field of screening devices, and in particular relates to a ganoderma lucidum spore powder screening and impurity removal device. Background Art

[0002] Before the spore powder of Ganoderma lucidum is broken, it needs to go through drying and screening processes. Among them, the screening and impurity removal process of Ganoderma lucidum spore powder is to remove the impurities and undesirable components of Ganoderma lucidum spore powder as much as possible, which is one of the important means to improve the purity of Ganoderma lucidum spore powder and ensure the quality of Ganoderma lucidum spore powder.

[0003] Existing Ganoderma lucidum spore powder screening devices mainly adopt vibration screening or air selection screening. These screening methods can perform a certain degree of impurity removal screening, but the impurity removal effect is still not ideal. For example, some Ganoderma lucidum spore powder is adhered to impurities and cannot be screened well. At the same time, it is easy to stick and clog. Summary of the invention

[0004] The purpose of the present invention is to provide a device for screening and removing impurities from ganoderma lucidum spore powder, so as to overcome the problem that the existing ganoderma lucidum spore powder screening and removing impurities has a poor effect.

[0006] A ganoderma lucidum spore powder screening and impurity removal device comprises a frame, a first screening chamber, a second screening chamber, a drum screen, a vibrating screen, a vibrating motor, a rotating motor and a feeding hopper.

[0007] The feed hopper is connected to one end of the first screening chamber and is used to introduce the Ganoderma lucidum spore powder into the first screening chamber;

[0008] The drum screen is arranged in the first screening chamber, the lower part of the first screening chamber is connected with the second screening chamber, and the first screening chamber is provided with a feed inlet at one end and a debris discharge outlet at the other end;

[0009] The vibrating screen is arranged in the second screening chamber, support rods are arranged at the upper parts of both sides of the second screening chamber, a discharge port is arranged at the upper part of one side of the second screening chamber, and a discharge port is arranged at the bottom;

[0014] The mesh aperture of the drum screen is larger than that of the vibration screen. After the ganoderma lucidum spore powder is broken up and screened once by the drum screen, it is screened for the second time by the vibration screen, thereby further improving the screening effect.

[0015] Preferably, it further comprises a conveying device, wherein the upper part of one end of the conveying device is connected to the feed hopper, and the other end of the conveying device is connected to the feed port of the first screening chamber, and the conveying device is a screw conveying device.

[0016] Preferably, the rotating shaft of the conveying device is coaxially arranged with the rotating shaft of the drum screen, and is driven to rotate by the same rotating motor.

[0017] Preferably, a brush is provided at the middle and upper part of the inner side of the first screening cavity, and the bristles of the brush abut against the outer side of the first screening cavity.

[0018] Preferably, the brush is swingably connected to the first screening chamber via a hinge, and a spring is provided between the brush and the first screening chamber; a connecting rod is also hinged on the hinge, and the other end of the connecting rod is fixed to the vibration motor or the vibration screen. The connecting rod can transmit the vibration of the vibration motor or the vibration screen to the brush, further improving the cleaning effect of the brush and preventing clogging.

[0024] Compared with the existing technology, the present invention has the following beneficial effects:

[0025] 1. The present invention can better break up and screen the Ganoderma lucidum spore powder by setting up a first screening chamber and a second screening chamber that are interconnected, and setting up a drum screen in the first screening chamber and a vibrating screen in the second screening chamber. The impurities discharged from the impurity discharge port at the end of the drum screen are collected separately, and the powder discharged from the discharge port above the vibrating screen can be circulated to the feed port through a circulation pipe with a pneumatic powder pump to break up and screen again, and the Ganoderma lucidum spore powder discharged from the discharge port below the vibrating screen is the required impurity-removed Ganoderma lucidum spore powder, which can be dried, broken and other subsequent processes.

[0026] 2. The present invention can solve the problem of feed blockage by arranging a conveying device to convey the Ganoderma lucidum spore powder to the drum screen, and the feed hopper can be filled with more Ganoderma lucidum spore powder at one time, without the need for manual feeding in real time. The conveying device adopts a spiral conveying device, which can break up some blocky powders while conveying the Ganoderma lucidum spore powder, which is beneficial for subsequent screening. The transfer shaft of the conveying device can be coaxially arranged with the drum screen and share a rotating motor. The transfer motor can be arranged below the conveying device through a reducer, and the overall structure is compact and reasonable.

[0027] 3. The present invention can clean the drum screen by arranging a brush abutting against the drum screen on the inner side of the first screening chamber to prevent the drum screen from being blocked and affecting screening. The brush is hinged to the first screening chamber through a hinge and is further fixed by a spring. At the same time, a connecting rod connected to the vibration motor or the vibration screen is also hinged. The vibration of the vibration motor or the vibration screen can be transmitted to the brush through the connecting rod, which can improve the cleaning effect of the brush and better prevent the drum screen from being blocked. At the same time, the powder on the brush can also fall off in time for subsequent screening.

[0028] 4. The present invention can circulate the Ganoderma lucidum spores discharged from between the drum screen and the vibrating screen to the feed hopper for secondary screening by sleeve-connecting the circulation pipe at the discharge port and arranging a pneumatic powder pump on the circulation pipe, thereby avoiding the waste of Ganoderma lucidum spore powder. Among them, a branch pipe connected to the circulation pipe can be arranged at the end of the drum screen and above the discharge port, so that this part of the powder can also be recovered and screened for secondary screening, and at the same time, the generation of dust can be reduced.

[0046] The drum screen 4 is arranged in the first screening chamber 2, and is driven to rotate by the rotating motor 7 arranged outside the first screening chamber 2;

[0047] The vibrating screen 5 is disposed on the upper part of the second screening chamber 3, and the vibrating screen 5 is connected to the supporting rod through a spring 14. One end of the vibrating screen 5 is higher than the other end, and the lower end of the vibrating screen 5 is disposed above the discharge port 31;

[0049] The vibration motor 6 is disposed below the vibration screen 5 and is used to drive the vibration screen 5 to vibrate up and down;

[0050] The control device 10 is electrically connected to the vibration motor 6 and the rotary motor 7 to control the operation of the vibration motor 6 and the rotary motor 7 .

[0051] The mesh aperture of the drum screen 4 is larger than that of the vibrating screen 5. After the ganoderma lucidum spore powder is once dispersed and screened by the drum screen 4, it is screened twice by the vibrating screen 5 to further improve the screening effect. In the present application, the drum screen 4 and the vibrating screen 5 can both adopt existing structures, or be assembled using existing structures. The invention point of the present application is not the specific structure of the drum screen 4 and the vibrating screen 5, but the combination of the two screens to further improve the screening effect. Among them, the drum screen 4 selects a drum screen with a rotating shaft.

[0052] Combination Figure 2 In this embodiment, the conveying device 9 is a spiral conveying device 9, that is, the conveying device 9 includes a horizontally arranged rotating shaft and blades arranged in a spiral shape along the rotating shaft. The rotating shaft of the conveying device 9 is coaxially arranged with the rotating shaft of the drum screen 4, and is driven to rotate by the same rotating motor 7. Specifically, the rotating motor 7 is arranged below the conveying device 9, and the rotating motor 7 is connected to the rotating shaft of the conveying device 9 through a belt conveyor 11. Of course, the rotating motor 7 can also be connected to a reducer to drive the rotating shafts of the conveying device 9 and the drum screen 4 to rotate. The overall structure of the equipment is compact and reasonable, and the use of motors can be reduced.

[0053] Combination Figure 3 A brush 12 is provided in the middle and upper part of the inner side of the first screening chamber 2, and the bristles of the brush 12 abut against the outer side of the first screening chamber 2. Specifically, the brush 12 is swingably connected to the first screening chamber 2 through a hinge 13, and a spring 14 is also provided between the brush 12 and the first screening chamber 2; a connecting rod 15 is also hinged on the hinge 13, and the other end of the connecting rod 15 is fixed to the vibration motor 6 or the vibration screen 5.

At the same time, the powder on the horse brush can also fall off in time for subsequent screening processing.

[0054] Combination Figure 2The upper part of the second screening chamber 3 is square and the lower part is funnel-shaped. The vibrating screen 5 is arranged at the upper part of the second screening chamber 3. The powder that cannot pass through the vibrating screen 5 is discharged from the discharge port 31, and the powder that can pass through the vibrating screen 5 is discharged from the discharge port 32 and collected for the next process. Among them, a bag can be tied at the discharge port 31 to collect the powder and reduce dust.

[0055] Combination Figure 4 In other embodiments, the discharge port 31 is connected to the circulation pipe 16, the other end of the circulation pipe 16 is connected to the feed hopper 8, and the circulation pipe 16 is provided with a pneumatic powder pump 17. Further, a powder cavity is left between the end of the drum screen 4 and the first screening cavity 2, the discharge port 31 is provided at the lower part of the powder cavity, and a branch pipe 18 connected to the circulation pipe 16 is provided in the upper part of the powder cavity. By sleeve-connecting the circulation pipe 16 at the discharge port 31 and providing a pneumatic powder pump 17 on the circulation pipe 16, the ganoderma lucidum spores discharged from between the drum screen 4 and the vibrating screen 5 can be circulated and transported to the feed hopper 8 for secondary screening, thereby avoiding the waste of ganoderma lucidum spore powder. Among them, a branch pipe 18 connected to the circulation pipe 16 can also be provided at the end of the drum screen 4 and above the discharge port 31, so that this part of the powder can also be recovered and screened for secondary screening, and at the same time, the generation of dust can be reduced.

[0056] The present screening and impurity removal device is used to screen and remove impurities from the Ganoderma lucidum spore powder. The Ganoderma lucidum spore powder is loaded into the feed hopper 8, and the rotating motor 7 and the vibrating motor 6 are started by the control device 10. The conveying device 9 conveys the Ganoderma lucidum spore powder dropped from the feed hopper 8 to the drum screen 4 for primary screening, and impurities with larger particle sizes are discharged from the impurity discharge port 21, while impurities with smaller particle sizes pass through the screen of the drum screen 4 and enter the vibrating screen 5 for further screening. The powder discharged from the discharge port 31 above the vibrating screen 5 can be circulated to the feed port manually or through a circulation pipe 16 with a pneumatic powder pump 17, and then broken up and screened again. The Ganoderma lucidum spore powder discharged from the discharge port 32 below the vibrating screen 5 is the required impurity-removed Ganoderma lucidum spore powder, which can be subjected to subsequent processes such as drying and wall breaking.

[0057] In summary, the present invention can better break up and screen the Ganoderma lucidum spore powder by setting up the first screening chamber 2 and the second screening chamber 3 which are interconnected, and respectively setting up the drum screen 4 in the first screening chamber 2 and the vibrating screen 5 in the second screening chamber 3. Among them, the impurities discharged from the impurity discharge port 21 at the end of the drum screen 4 are collected separately, the powder discharged from the discharge port 31 above the vibrating screen 5 can be circulated to the feed port through the circulation pipe 16 with the pneumatic powder pump 17 to be broken up and screened again, and the Ganoderma lucidum spore powder discharged from the discharge port 32 below the vibrating screen 5 is the required impurity-removed Ganoderma lucidum spore powder, which can be dried, broken and other subsequent processes.
