Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and more specifically, to a double cone drum dry powder mixer. Background Technology

[0002] A double cone mixer is a mixing device that uses a rotating tank to mix various powders evenly. It is a mechanical device that feeds powdered or granular materials into a double cone container via vacuum conveying or manual feeding. As the container rotates continuously, the materials undergo complex impact movements within the container, achieving a uniform mixture.

[0003] Currently, the main drive structures of double cone drum dry powder mixers on the market are either a reducer directly connected to the central shaft or a chain-disc drive for the central shaft. The main disadvantages are: the reducer-direct-drive solution requires a high-performance reducer and is more expensive for the same load; the chain-disc drive solution is cheaper but noisier, and it cannot perform multiple mixing processes simultaneously, resulting in poor mixing effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a double cone drum dry powder mixer to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A double-cone drum dry powder mixer includes a mixing drum, a first mixing component is disposed inside the mixing drum, and a portion of the first mixing component is disposed outside the mixing drum. A second mixing component is disposed outside the mixing drum, and a controller is disposed on one side of the second mixing component. The first mixing component includes a sealing cover, which is hinged to one end of the mixing drum. A fixing hook is symmetrically disposed on the sealing cover, and a fixing buckle is symmetrically disposed on the mixing drum, with the fixing buckle connected to the fixing hook.

[0008] Furthermore, in order to better ensure the mixing effect, a first motor is installed at one end of the mixing cylinder via a fixed frame. The output shaft of the first motor is equipped with a first bevel gear, and a second bevel gear is meshed with the first bevel gear. A rotating rod is installed on the second bevel gear.

[0009] Furthermore, to better ensure the mixing effect, one end of the rotating rod extends from the outside of the mixing cylinder to the inside of the mixing cylinder. The end of the rotating rod located inside the mixing cylinder is connected to a cleaning plate, and the cleaning plate is in contact with the inner wall of the mixing cylinder. Multiple mixing blades are provided on the rotating rod.

[0010] Furthermore, the first mixing assembly also includes a first conveying chamber and a second conveying chamber. The first conveying chamber and the second conveying chamber are respectively opened inside the rotating rod and the cleaning plate, and the second conveying chamber is connected to the first conveying chamber. The second conveying chamber is connected to multiple one-way nozzles. One end of the rotating rod is connected to a conveying pump through a rotary joint. The conveying pump is mounted on the mixing cylinder through a fixed frame.

[0011] Furthermore, to better ensure quiet operation and transmission performance, the second hybrid component includes a support base. A second motor is fixedly mounted on one end of the support base by bolts. The output shaft of the second motor is equipped with a first pulley, on which a transmission belt is fitted. A protective cover is provided around the support base.

[0012] Furthermore, a second pulley is connected to the transmission belt, and a first transmission shaft is provided on the second pulley. One end of the first transmission shaft extends from the outside of the support to the inside of the support. The end of the first transmission shaft located inside the support is connected to the mixing drum, and the controller is located on the outside of the support.

[0013] Furthermore, a second drive shaft is connected to the mixing drum, and the second drive shaft is mounted on a support base via bearings, with guardrails symmetrically arranged between the support bases.

[0014] The beneficial effects of this utility model are as follows: By setting up a second mixing component, the problems of high cost of the reducer or high noise of the chain in the current mixer are solved. At the same time, by setting up a belt drive structure, the output torque is greatly improved, the load capacity is increased, and the noise and cost are greatly reduced under the same motor power configuration. By setting up a first mixing component, it can cooperate with the second mixing component to perform multiple mixing processes on the dry powder during the rotation of the mixing drum, thereby better ensuring the mixing effect and mixing efficiency. By setting up a guardrail, the risk of collision with the mixer can be avoided during the rotation of the mixer, thereby achieving the protection effect of the mixer. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, a double cone drum dry powder mixer is provided.

[0027] Example 1;

[0028] like Figures 1-7 As shown, a double-cone drum dry powder mixer according to an embodiment of the present invention includes a double-cone drum mixing cylinder 1. A discharge pipe 7 is connected to the outside of the mixing cylinder 1 for outputting the mixed dry powder. A control valve is provided on the discharge pipe 7, and the discharge pipe 7 is connected to the inside of the mixing cylinder 1. A first mixing component 2 is provided inside the mixing cylinder 1 for performing a first mixing treatment on the incoming dry powder. A portion of the first mixing component 2 is located outside the mixing cylinder 1. A second mixing component 3 is provided outside the mixing cylinder 1 for performing a second mixing treatment on the incoming dry powder. A controller 4 is provided on one side of the second mixing component 3.

[0029] Example 2;

[0030] like Figures 1-7 As shown, according to an embodiment of the present invention, a double cone drum dry powder mixer includes a first mixing component 2 comprising a sealing cover 201, which is hinged to one end of a mixing drum 1. A fixing hook 202 is symmetrically arranged on the sealing cover 201, and a fixing buckle 203 is symmetrically arranged on the mixing drum 1, with the fixing buckle 203 connected to the fixing hook 202. A first motor 204 is mounted on one end of the mixing drum 1 via a fixing frame. A first bevel gear 205 is mounted on the output shaft of the first motor 204. A second bevel gear 206 is meshed on the first bevel gear 205. A rotating rod 207 is mounted on the second bevel gear 206. One end of the rotating rod 207 extends from the outside of the mixing drum 1 to the inside of the mixing drum 1. A cleaning plate 208 is connected to the end of the rotating rod 207 located inside the mixing drum 1, and the cleaning plate 208 contacts the inner wall of the mixing drum 1. Multiple mixing blades 209 are mounted on the rotating rod 207.

[0031] The first mixing assembly 2 also includes a first conveying chamber 210 and a second conveying chamber 211. The first conveying chamber 210 and the second conveying chamber 211 are respectively opened inside the rotating rod 207 and the cleaning plate 208, and the second conveying chamber 210 is connected to the first conveying chamber 211. The second conveying chamber 211 is connected to a plurality of one-way nozzles 212. One end of the rotating rod 207 is connected to a conveying pump 213 through a rotary joint. A filter structure is provided at the input end of the conveying pump 213 (not shown in detail in the figure). The conveying pump 213 is mounted on the mixing cylinder 1 through a fixing frame 2.

[0032] In practical applications, when it is necessary to add mixed dry powder, the dry powder to be mixed can be put into the mixing cylinder 1 by the cooperation of the sealing cover 201, the fixing hook 202, and the fixing buckle 203. Then, the controller 4 starts the first motor 204. Then, the output shaft of the first motor 204 drives the first bevel gear 205 to rotate in the forward direction. Then, the first bevel gear 205 and the second bevel gear 206 mesh with each other and drive the rotating rod 207 to rotate in the forward direction (the rotation speed of the rotating rod 207 is 200 rpm). This causes the mixing blade 209 and the cleaning plate 208 to rotate. During the mixing of multiple dry powders, the controller 4 starts the delivery pump 213. Then, the delivery pump 213 generates suction to draw in external gas and then filters it. Then, the gas enters the first delivery chamber 210 and the second delivery chamber 211 through the rotating rod 207. Then, the gas is output through the one-way nozzle 212, thus ensuring that the dry powder to be mixed is mixed.

[0033] Example 3;

[0034] like Figures 1-7 As shown, according to an embodiment of the present invention, a double-cone drum dry powder mixer includes a second mixing component 3 comprising a support base 301. A second motor 302 is fixedly mounted on one end of the support base 301 by bolts. The output shaft of the second motor 302 is provided with a first pulley 303. A transmission belt 304 is sleeved on the first pulley 303. A protective cover 5 is provided around the support base 301. A second pulley 305 is connected to the transmission belt 304. A first transmission shaft 306 is provided on the second pulley 305. One end of the first transmission shaft 306 extends from the outside of the support base 301 to the inside of the support base 301. The end of the first transmission shaft 306 located inside the support base 301 is connected to the mixing drum 1. A controller 4 is provided on the outside of the support base 301. A second transmission shaft 307 is connected to the mixing drum 1 and is mounted on the support base 301 by bearings. Guardrails 6 are symmetrically inclined between the support bases 301.

[0035] In practical applications, during the mixing process inside the mixing drum 1, the controller 4 starts the second motor 302. Then, the output shaft of the second motor 302 drives the first pulley 303 to rotate in the opposite direction, which in turn drives the transmission belt 304 to rotate. Subsequently, the transmission belt 304 drives the second pulley 305 to rotate, thereby driving the first transmission shaft 306 and the mixing drum 1 to rotate in the opposite direction. At the same time, the second transmission shaft 307 is also driven to rotate, thus realizing multiple mixing processes of dry powder. At the same time, it can also significantly increase the output torque, increase the load capacity, significantly reduce noise, and reduce costs.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to put in the mixed dry powder, the dry powder to be mixed can be put into the mixing cylinder 1 by the cooperation of the sealing cover 201, the fixing hook 202, and the fixing buckle 203. Then, the controller 4 starts the first motor 204, and then the output shaft of the first motor 204 drives the first bevel gear 205 to rotate in the forward direction. Then, the first bevel gear 205 and the second bevel gear 206 mesh with each other and drive the rotating rod 207 to rotate in the forward direction (the rotation speed of the rotating rod 207 is 200 rpm), thereby driving the mixing blade 209 and the cleaning plate 208 to rotate. During the mixing of multiple dry powders, the controller 4 starts the delivery pump 213, and then the delivery pump 213 generates suction to draw in external gas and then filter it. Next, the gas enters the first conveying chamber 210 and the second conveying chamber 211 through the rotating rod 207, and then outputs the gas through the one-way nozzle 212, thereby ensuring that the dry powder to be mixed is mixed. When the mixing process is carried out inside the mixing cylinder 1, the controller 4 starts the second motor 302, and then the output shaft of the second motor 302 drives the first pulley 303 to rotate in the opposite direction, which in turn drives the transmission belt 304 to rotate. Then the transmission belt 304 drives the second pulley 305 to rotate, thereby driving the first transmission shaft 306 and the mixing cylinder 1 to rotate in the opposite direction. At the same time, the second transmission shaft 307 is also driven to rotate, thereby realizing multiple mixing processes of dry powder. At the same time, it can also significantly increase the output torque, increase the load capacity, significantly reduce noise, and reduce costs.
