Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a homogenizing mixing device for dry powder biological culture media. Background Technology

[0002] Dry powder culture medium is a product made by dehydrating prepared culture medium. This form is convenient for storage and sales. When using it, it only needs to be dissolved in water according to a certain ratio. In the production of dry powder culture medium, stirring equipment is usually used to stir and mix the materials to complete the processing.

[0003] When using existing homogenizing equipment for mixing dry powder biological culture media, the function of the equipment is to mix the materials. Dry powder culture media requires various materials to be mixed and homogenized according to different weight ratios before being packaged. The mass difference of the materials to be mixed each time is relatively large. In the past, during the mixing process, some powders or particles with higher density and heavier mass would always remain at the bottom of the mixing drum, which would prevent uniform mixing. Utility Model Content

[0004] The purpose of this invention is to provide a homogenizing and mixing device for dry powder biological culture media, so as to solve the problem mentioned in the background art that in the previous homogenizing and mixing machine, some powders or particles with higher density and heavier mass will always remain at the bottom of the mixing drum during the mixing process, and cannot be mixed evenly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a homogenizing and stirring device for dry powder biological culture media, comprising a support frame:

[0006] A mixing drum is connected to one side of the support frame. A drum cover is provided at the top of the mixing drum, and a discharge port is provided at the bottom of the mixing drum. A motor control cabinet is connected to the other side of the support frame. An outer spiral ribbon is connected to one side of the motor control cabinet, and an inner spiral ribbon is provided inside the outer spiral ribbon. Compressed air outlets are provided on both sides of the surface of the mixing drum. Telescopic support rods are connected to both sides of the surface of the mixing drum. A stainless steel cover plate is connected to one end of each telescopic support rod. A blower is connected to the bottom of the mixing drum.

[0007] Preferably, the rotation of the outer and inner spiral ribbons is controlled by a motor control cabinet, and a motor is installed at the top of the motor control cabinet to drive the outer spiral ribbon to rotate.

[0008] Preferably, the support frame is configured as two sets and connected to both ends of the mixing drum respectively. A slot is opened on one side of the support frame, and the motor control cabinet and the outer spiral ribbon are connected through the slot opened in the support frame.

[0009] Preferably, the outer and inner spiral ribbons are paddle-shaped, and the stainless steel cover plate is supported for opening and closing by a telescopic support rod.

[0010] Preferably, the outer spiral ribbon gathers the material from both sides to the center, and the inner spiral ribbon transports the material from the center to both sides.

[0011] Preferably, the bottom surface of the mixing drum has three sets of air inlets, and the blower is located on the surface of the air inlet of the mixing drum, and the blower blows air into the mixing drum from the bottom of the mixing drum.

[0012] Preferably, the compressed air outlet can discharge the air blown in by the blower, and the stainless steel cover plate can seal the blower.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Pour the material into the mixing drum by opening the lid. Then, use the motor control cabinet to control the rotation of the outer spiral ribbon. While the outer spiral ribbon rotates, it drives the inner spiral ribbon to operate synchronously. The outer spiral ribbon gathers the material from both sides to the center, while the inner spiral ribbon conveys the material from the center to both sides, forming convection mixing, thus making the mixing more uniform. Open the stainless steel cover plate and use the telescopic support rod to support it, thereby opening the compressed air outlet. Use the blower to blow air into the mixing drum, continuously blowing the particles at the bottom of the mixing drum into the outer and inner spiral ribbons, ensuring that all materials are evenly mixed. The air is discharged through the compressed air outlet, thus achieving a mixing effect for all materials and avoiding the problem of powders or particles with high density or weight remaining at the bottom of the mixing drum and failing to be mixed evenly.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A homogenizing and mixing device for dry powder biological culture medium, comprising a support frame 1:

[0024] A mixing drum 2 is connected to one side of the support frame 1. A drum cover 3 is provided at the top of the mixing drum 2, and a discharge port 4 is provided at the bottom of the mixing drum 2. A motor control cabinet 5 is connected to the other side of the support frame 1. An outer layer screw ribbon 6 is connected to one side of the motor control cabinet 5, and an inner layer screw ribbon 7 is provided inside the outer layer screw ribbon 6. Compressed air outlets 8 are provided on both sides of the surface of the mixing drum 2. Telescopic support rods 9 are connected to both sides of the surface of the mixing drum 2. A stainless steel cover plate 10 is connected to one end of the telescopic support rod 9. A blower 11 is connected to the bottom of the mixing drum 2. The mixing equipment performs conventional mixing of materials, and at the same time, the blower 11 blows compressed air into the mixing drum 2. The compressed air flows upward from the bottom of the mixing drum 2, lifting up the powder or particles with higher density and heavier mass at the bottom, so that they participate in the mixing process. The compressed air is discharged through the compressed air outlet 8. Since a filter screen is provided on the compressed air outlet 8, the material will not leak out. The internal material of the mixing drum 2 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further description is made.

[0025] Furthermore, the rotation of the outer spiral ribbon 6 and the inner spiral ribbon 7 is controlled by the motor control cabinet 5. A motor is installed at the top of the motor control cabinet 5 to drive the outer spiral ribbon 6 to rotate, thereby realizing the control of the outer spiral ribbon 6 by the motor installed at the top of the motor control cabinet 5.

[0026] Furthermore, the support frame 1 is configured as two sets and connected to both ends of the mixing drum 2 respectively. A slot is opened on one side of the support frame 1. The motor control cabinet 5 and the outer screw ribbon 6 are connected through the slot opened in the support frame 1, so that the motor control cabinet 5 and the outer screw ribbon 6 can be connected through the slot opened in the support frame 1.

[0027] Furthermore, the outer spiral ribbon 6 and the inner spiral ribbon 7 are paddle-shaped, and the stainless steel cover plate 10 is supported by the telescopic support rod 9 for opening and closing. The telescopic support rod 9 supports the angle of the stainless steel cover plate 10. Both ends of the telescopic support rod 9 are located on the inner side, and the stainless steel cover plate 10 can be effectively closed through the telescopic support rod 9.

[0028] Furthermore, the outer spiral ribbon 6 gathers the material from both sides to the center, while the inner spiral ribbon 7 conveys the material from the center to both sides, achieving a convective mixing effect of the material through the outer spiral ribbon 6 and the inner spiral ribbon 7.

[0029] Furthermore, three sets of air inlets are provided on the bottom surface of the mixing drum 2, and the blower 11 is set on the surface of the air inlet of the mixing drum 2. The blower 11 blows air from the bottom of the mixing drum 2 into the interior of the mixing drum 2, so that the material at the bottom of the mixing drum 2 is blown into the outer spiral ribbon 6 and the inner spiral ribbon 7 for mixing.

[0030] Furthermore, the compressed air outlet 8 can discharge the air blown in by the blower 11, and the stainless steel cover plate 10 can seal the blower 11, thus enabling the blower 11 to be turned on and off through the stainless steel cover plate 10.

[0031] Working principle: When using the homogenizing and mixing equipment for mixing dry powder biological culture medium, the material is poured into the mixing drum 2 by opening the drum cover 3. Then, the outer spiral ribbon 6 is rotated by the motor control cabinet 5, and the inner spiral ribbon 7 is driven to operate synchronously while the outer spiral ribbon 6 rotates. The outer spiral ribbon 6 gathers the material from both sides to the center, and the inner spiral ribbon 7 conveys the material from the center to both sides, forming convection mixing, which makes the mixing more uniform. The stainless steel cover plate 10 is opened and supported by the telescopic support rod 9, so that the compressed air outlet 8 is opened. The blower 11 blows air into the mixing drum 2, continuously blowing the particles at the bottom of the mixing drum 2 into the outer spiral ribbon 6 and the inner spiral ribbon 7, ensuring that all materials can be mixed evenly. The air is discharged through the compressed air outlet 8, thereby achieving the mixing effect of all materials.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
