Description

Technical Field

[0001] The utility model relates to a high-speed mixer which is convenient for cleaning residual materials and belongs to the technical field of material mixing and stirring. Background Art

[0002] High-speed mixers are widely used in the chemical, pharmaceutical, food, plastic, and daily chemical industries to mix and homogenize different materials efficiently, evenly, and quickly. The principle is to generate a strong shearing effect through the high-speed rotating stirring blades, so that the materials are quickly and fully mixed in the cylinder. In order to achieve uniform mixing of materials, the blades of the high-speed mixer will continue to rise in temperature during actual use due to their high speed and continuous high-speed friction contact with the materials to be mixed. For the blades with sharp edges, high temperature will cause them to soften to a certain extent, and the high-speed contact and friction with the materials will increase the wear of the blades, resulting in a shorter service life of the blades, and is not conducive to the long-term operation of the equipment.

[0003] And for some special mixed materials, such as when lithium battery raw materials are mixed with adhesives, the continuous heating of the rotor blades may cause the adhesive (such as PVDF) to decompose toxic gases, the volatilization of the adhesive may affect the material ratio, and the adhesive may bond to the surface of the rotor blade in advance, causing the rotor blade to wear or agglomerate and be difficult to clean. Therefore, in order to prevent the rotor blade from heating up and to increase the operating time of the equipment, it is particularly necessary to cool the rotor blade. However, the rotor blade is covered by the material when mixing the materials. If you want to cool the rotor blade, you can only cool the entire tank body, which not only consumes a lot of power but also makes it difficult to directly achieve a cooling effect at the high-speed friction position.

[0040] The utility model provides a high-speed mixer which is convenient for cleaning residual materials. An air path is arranged inside the rotary blade 6, and cooling gas is supplied to the interior of the rotary blade 6 when the rotary blade 6 rotates continuously by utilizing a rotating ventilation structure, so as to realize low-temperature contact between the rotary blade 6 and the mixed material. The low temperature of the blade can also transmit the temperature to the mixed material, thereby effectively improving the long-term operation time of the equipment and ensuring the mixing effect of the materials, and reducing the wear of the rotary blade 6. In order to realize the structural function of the device, the device is provided here, including a base 1 as the structural basis of the high-speed mixer. A mixing tank 2 is fixedly arranged on the base 1, and a stirring and mixing component is rotatably installed at the bottom position of the mixing tank 2. A driving device 3 for driving the stirring and mixing component to rotate is also provided on the base 1. The driving device 3 is used to drive the stirring and mixing component to stir and rotate at a high speed inside the mixing tank 2, so as to realize further crushing of the stirred material and uniform mixing of the materials. Specifically, the stirring and mixing component is provided here and includes:

[0041] Rotating tube 4, such as Fig.11 As shown, the rotating tube 4 is rotatably arranged on the base 1 and passes through the bottom of the mixing tank 2. The rotating tube 4 is connected to the bottom of the mixing tank 2 through a sealed bearing. The rotating tube 4 is connected to the output end of the driving device 3 through a transmission connection. The transmission connection method can refer to Fig. 9 As shown, a belt and a pulley are connected, and a first vent 401 and a second vent 402 are provided on the rotating tube 4; an annular mounting seat 5, as shown Figure 6 As shown, the annular mounting seat 5 includes a circular ring body 501 fixedly mounted on the rotating tube 4, and a plurality of rotating blades 6 are mounted on the outer circumference of the circular ring body 501 in a circular array. Figure 4 As shown, a gas path 601 is provided inside the rotor blade 6. Fig.12 and Fig.13 As shown, the air inlet and the air outlet of the air circuit 601 are connected to the first air hole 502 and the second air hole 503 opened on the annular body 501 respectively, and there is a height difference between the air inlet and the air outlet of the air circuit 601. The first air hole 502 of the annular body 501 is connected to the first air vent 401, and the second air hole 503 of the annular body 501 is connected to the second air vent 402; the air inlet and outlet support column 7 is relatively fixed to the base 1, which can be referred to Fig. 9As shown, it is fixedly installed on the support frame 10, wherein the air intake and exhaust support column 7 includes a positioning rod 701 and a column head 702 arranged at the end of the positioning rod 701, the outer diameter of the column head 702 matches the inner diameter of the rotating tube 4, and the column head 702 is respectively provided with a first air vent 703 and a second air vent 704, the first air vent 703 is connected to the cold air source, the first air vent 703 is used to be connected with the air inlet of the air path 601 when the rotating tube 4 rotates, and the second air vent 704 is used to be connected with the air outlet of the air path 601 when the rotating tube 4 rotates. When the stirring and mixing assembly is rotated by the driving device 3, the cold air source is first transmitted from the first air hole 703 to the first air port 401, and the first air port 401 then transmits the cold air to the air inlet of the air path 601 through the first air hole 502. After the cold air circulates in the air path 601, it is output to the outside through the second air hole 503, the second air port 402 and the second air hole 704 respectively, so as to realize the rapid cooling of the rotary blade 6. In order to improve the cooling efficiency of the rotary blade 6, it is preferred to arrange the air path 601 in a mesh shape inside the rotary blade 6, so as to increase the cooling area of ​​the air path 601 and thus improve the heat exchange efficiency. The cold air source can preferably be liquid nitrogen. Therefore, a liquid nitrogen storage tank 8 and an air supply pipe 9 connected to the air inlet and exhaust support column 7 for transmitting liquid nitrogen can be preferably arranged on the device. When the above device is in use, the metal rotor blade 6 is quickly cooled down by the cold air source. After the temperature is transmitted to the surface of the blade, it can also cool down the nearby materials to be mixed. When the operation is performed in a slow stirring manner, the materials to be mixed can be pre-regulated to a certain low temperature level. When the equipment is running at high speed, the heat generated by friction is taken away by the cold air and heat exchange interaction is realized, so as to keep the rotor blade 6 working at a low temperature level for a long time. Since the low temperature ensures the rigidity of the blade head position of the rotor blade 6, the wear of the rotor blade 6 caused by high temperature softening can be effectively prevented, so as to increase the service life and service life of the equipment. In addition, the low temperature can ensure that the long-term stirring action will not increase the temperature inside the container, so as to ensure the good chemical properties of the materials to be mixed and the stability of the mixing process.

[0042] The embodiment of the utility model provides a high-speed mixer which is convenient for cleaning residual materials. In order to prevent powdered materials to be mixed from entering the fitting gap between the air inlet and outlet support column 7 and the rotating tube 4, one end face of the annular mounting seat 5 is preferably a sealing surface, and the sealing surface is used to shield the rotating tube 4 and the air inlet and outlet support column 7, which is not shown in the figure. Preferably, the sealing surface is in the shape of a bullet head hemispherical, which is smooth and not easy to adhere to materials.

[0043] The embodiment of the utility model provides a high-speed mixer that is convenient for cleaning residual materials. Considering that the time for the high-speed rotating impeller 6 to supply cold air to the air path 601 is very short when it briefly passes through the first air hole 502, it may be difficult for the cold air source to enter the air path 601 to achieve cooling of the impeller 6. For this reason, the first air vent 401 and the second air vent 402 are both set to be long grooves, and the first air vent 401 and the second air vent 402 are both provided with multiple and arranged in a circular array on the rotating tube 4. The first air vent 401 and the second air vent 402 are offset in position in the axial direction of the rotating tube 4. The offset is matched with the position height difference between the air inlet and the air outlet of the air path 601. Assuming that the impeller 6 rotates at a speed of one revolution per second, if the long groove-shaped air vent occupies half of the arc of the rotating tube 4, the ventilation time can be extended to 0.5 seconds. By supplying the cold air source at a certain air pressure, the impeller 6 can meet the air supply and ventilation needs when rotating at a high speed.

[0044] The utility model provides a high-speed mixer that is convenient for cleaning residual materials. Considering that the overall volume of the rotor blade 6 is small, the rotor blade 6 can be processed by first opening a gas path 601 inside it, and then processing its overall shape. The side shape of the rotor blade 6 is usually as follows: Fig.12As shown, it can be clearly seen that the air inlet and the air outlet of the air path 601 need to have a certain degree of skewness deviation in the lateral position so that the air holes can be easily opened. If the positions of the first air vent 401 and the second air vent 402 are opened blindly, the air outlet channel may not be connected when the cold air supply channel is connected, resulting in the cold air being unable to normally enter the air path 601 to realize gas circulation. For this reason, it is also necessary to set the first air vent 401 and the second air vent 402 to have the same size, shape, and number of annular arrays. The first air vent 401 has a rotation angle offset relative to the second air vent 402. The offset of the rotation angle is the arc angle formed by the air inlet and the air outlet of the air path 601 and the rotation axis of the air path 601. This state can ensure that the rotating tube 4 maintains the air inlet and the air outlet in a closed state or an open state at the same time during rotation, thereby improving the heat exchange efficiency of the air path 601. In order to match the air connection between the air inlet and exhaust support column 7 and the rotating tube 4, the number and size of the first air hole 703 and the second air hole 704 opened on the column head 702 are the same, where as shown above, there is a height difference between the first air hole 703 and the second air hole 704, and the first air hole 703 has a rotation angle offset relative to the second air hole 704, and the offset of the rotation angle is the arc angle formed by the air inlet and outlet of the air path 601 and its rotation axis, and the rotation offset direction of the first air hole 703 relative to the second air hole 704 is the same as the rotation offset direction of the first air hole 401 relative to the second air hole 402, thereby ensuring that the rotating tube 4 can connect the first air hole 703 and the second air hole 704 at the same time when rotating.

[0045] The utility model provides a high-speed mixer that is convenient for cleaning residual materials, such as Fig.12 As shown in the rotor blade 6, since the height difference between the air inlet and the air outlet of the air path 601 is very short, it is difficult to open the air grooves with appropriate spacing to connect the corresponding air holes. In order to ensure the accuracy of the air hole connection and reduce the matching error to improve the ventilation yield, a first ventilation groove 504 matching the position of the first ventilation port 401 and a second ventilation groove 505 matching the position of the second ventilation port 402 are respectively provided on the inner side of the annular body 501 of the annular mounting seat 5, as shown in FIG. Figure 6 and Figure 7 As shown, specifically, the distance between the first ventilation groove 504 and the second ventilation groove 505 is greater than the radial height offset distance between the air inlet and the air outlet of the air path 601, and the first air hole 502 and the second air hole 503 are respectively connected to the first ventilation groove 504 and the second ventilation groove 505, and the corresponding first air hole 502 and the second air hole 503 can be directly inserted obliquely into the first ventilation groove 504 and the second ventilation groove 505, thereby increasing the matching distance with the air inlet and exhaust support column 7 to avoid the problem of low assembly yield.

[0046] The utility model embodiment provides a high-speed mixer that is convenient for cleaning residual materials. Since the oblique insertion method does not have good angle accuracy in processing the air holes, in order to facilitate the processing of the annular mounting seat 5, the height range of the column head 702 can be set to span the first ventilation groove 504 and the second ventilation groove 505. Specifically, the first air hole 502 passes through the inner position of the annular body 501 and is connected to the first ventilation groove 504 through the connecting groove 506, and the second air hole 503 passes through the inner position of the annular body 501 and is connected to the second ventilation groove 505 through the connecting groove 506. As a preferred embodiment, in order to avoid the staggered air grooves, the first air hole 502 and the second air hole 503 are arranged here within the range between the first ventilation groove 504 and the second ventilation groove 505, such as Figure 7 As shown, in this state, when the gas path 601 is connected, it is first connected to the corresponding ventilation groove through the corresponding connecting groove 506, and then the gas circulation is achieved.

[0047] The utility model provides a high-speed mixer that is convenient for cleaning residual materials. When the gas circuit 601 of the system works normally, the temperature rise will cause the temperature of the gas finally discharged by the cooling gas to rise. The higher the temperature, the greater the heat carried by the discharged gas. In order to facilitate monitoring whether the operation of the rotary blade 6 produces a high abnormal temperature, a connecting pipe 705 can be provided at the outlet position of the second vent hole 704 on the column head 702. The connecting pipe 705 passes through the position between the rotating tube 4 and the positioning rod 701, such as Fig.10 As shown, the outlet of the connecting pipe 705 is positioned on the base 1, and the base 1 is also provided with a first temperature sensor 11 for monitoring the outlet temperature. When the temperature of the first temperature sensor 11 rises abnormally, corresponding measures should be taken in time to prevent the temperature from rising further. If liquid nitrogen is used as the cooling source, its temperature is about minus one hundred degrees Celsius, and conventional infrared temperature sensors are no longer applicable. Correspondingly, low-temperature thermocouples or silicon diode temperature sensors can be selected. When supplying gas, if the air pressure of the cold air source is increased, the gas consumption speed will be very fast. If it is too low, it will be difficult to quickly change the air at a high speed. Therefore, it is also preferred to use compressed gas generated by other air compressors for mixed supply to avoid the situation of too low temperature or too fast gas consumption. Embodiment 2:

[0048] The embodiment of the utility model provides a high-speed mixing method of materials, including the above-mentioned high-speed mixer, which is used to provide a method of monitoring the temperature of the rotary blade 6 and performing feedback adjustment to achieve rapid and stable operation of the high-speed mixer. Specifically, the device part also includes a second temperature sensor 12 provided on the mixing tank 2. The specific method includes the following steps:

[0049] Add the material to be mixed into the mixing tank 2, introduce cold air into the first vent hole 703 of the air inlet and outlet support column 7, and drive the stirring and mixing assembly to rotate at a first speed, which is only used for simple and slow stirring of the material to pre-lower the temperature of the material to be mixed;

[0050] The temperature of the mixed material in the tank is detected by the second temperature sensor 12. When the temperature is lower than the set threshold, the stirring and mixing assembly is driven to rotate at a second speed. The second speed is used to quickly cut off the mixed material, crush large particles and ensure uniform mixing of the materials.

[0051] The temperature of the cold air discharged from the second vent hole 704 during the rotation process is detected by the first temperature sensor 11. When the first temperature sensor 11 detects that the temperature of the exhaust air is too high, the stirring and mixing component is driven to rotate at the third speed until the temperature is lower than the set threshold again, and then the stirring and mixing component is driven to rotate at the second speed or the fourth speed obtained by negative feedback regulation, wherein the second speed is higher than the first speed, the third speed is lower than the second speed and can be the first speed, the fourth speed is higher than the third speed and lower than the second speed, and the third speed can also be a speed manually set so that the temperature of the rotor blade 6 does not increase significantly;

[0052] Until the materials are mixed.

[0053] In the above-mentioned material mixing method, the first temperature sensor 11 can calculate the temperature change of the rotor blade 6, and can more intuitively reflect the temperature abnormality at the position of the rotor blade 6, and timely adjust the rotation speed of the equipment to avoid further increase in temperature, thereby monitoring the operating status of the rotor blade 6 and realizing corresponding automatic adjustment, maintaining the operation of the equipment and avoiding abnormal operation.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
