[0034] Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments, based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present application. The various technical features in the present application can be combined interactively under the premise of not being contradictory and conflicting.

[0035] With reference to Figure 1 and Figure 2 The embodiment of the present application provides a stirring device, which can solve the overheating problem in the stirring process, avoid the modification of the material due to overheating, avoid the wall sticking phenomenon, improve the rapid stirring and mixing effect of the material, and is also beneficial to subsequent cleaning and maintenance.

[0036] In the embodiment, the stirring device comprises a stirring cylinder 100, a stirring part 200 and a stirring driving part 300. The stirring cylinder 100 is provided with a stirring cavity 130, and is provided with a feeding port and a discharging port. The feeding port and the discharging port are respectively arranged in communication with the stirring cavity 130. The feeding port is used for feeding the material into the stirring cavity 130, and the discharging port is used for discharging the material in the stirring cavity 130. The output end of the stirring driving part 300 is drivingly connected with the stirring part 200. The stirring part 200 is arranged in the stirring cavity 130. Under the driving action of the stirring driving part 300, the stirring part 200 can rotate in the stirring cavity 130, so as to realize the stirring action of the material.

[0037] It is worth noting that in the embodiment, the stirring cylinder 100 is also provided with a cooling cavity 140, and the cooling cavity 140 is located at the outer periphery of the stirring cavity 130. The stirring cylinder 100 is provided with a cooling water outlet 150 and a cooling water inlet 160. The cooling water inlet 160 and the cooling water outlet 150 are respectively arranged in communication with the cooling cavity 140. When the temperature in the stirring cavity 130 is increased, the cooling water is introduced into the cooling cavity 140 from the cooling water inlet 160. The cooling water can flow along the cooling cavity 140 to the outer periphery of the stirring cavity 130, and can carry away part of the heat in the stirring cavity 130, so as to reduce the temperature in the stirring cavity 130, avoid the modification of the material due to overheating, and avoid the wall sticking phenomenon of the material due to overheating.

[0038] In the embodiment, the cooling water inlet 160 is arranged at the bottom of the stirring cylinder 100, and the cooling water outlet 150 is arranged above the cooling water inlet 160, and the cooling water flows out of the cooling water inlet 160 after filling the cooling cavity 140. It can be understood that, in this way, when the cooling water fills the cooling cavity 140 from bottom to top, the cooling water can surround the outside of the stirring cavity 130, thereby cooling each position in the cooling cavity 140. After the cooling water fills the cooling cavity 140, it can flow out of the cooling water outlet 150, so that the cooling water can flow in the cooling cavity 140, further improving the cooling effect of the cooling water on the stirring cavity 130.

[0039] It can be understood that a partition wall is arranged between the discharge port and the cooling cavity 140, which can separate the discharge port and the cooling cavity 140, so that the cooling cavity 140 and the stirring cavity 130 are isolated from each other, and the cooling water cannot enter the stirring cavity 130, thereby avoiding the influence of the cooling water on the material mixing ratio.

[0040] It can be understood that the stirring device can dry mix the powder or wet mix the powder.

[0041] In some embodiments, the stirring device is a wet stirring device, which further comprises a spraying component 400. Referring to Figure 2 The spraying component 400 is connected to the top of the stirring cavity 130 and is arranged downwardly. The required liquid mixture enters the stirring cavity 130 in a spraying manner through the spraying component 400, and is mixed and stirred with the powder, which can greatly improve the uniformity of the mixture of the liquid mixture and the powder, improve the stirring efficiency, and further avoid the heating phenomenon in the stirring process and reduce the risk of material wall sticking.

[0042] In the embodiment, the spraying component 400 is provided with two, and the two spraying components 400 can uniformly spray the liquid mixture in the stirring cavity 130. It can be understood that the spraying component 400 can also be provided in other quantities, such as one, three, etc., which are not limited here.

[0043] In some embodiments, referring to Figure 2The stirring device further comprises a material lifting plate 500, which is connected to the inner side wall of the stirring cavity 130 and arranged at the upper end of the stirring cavity 130. Before stirring starts, the material generally settles at the bottom of the stirring cavity 130. Through the driving action of the stirring driving part 300, the stirring part 200 rotates to make the material fly in the stirring cavity 130. Under the rotating action of the stirring part 200, the material is lifted in a vortex along the inner wall of the stirring cavity 130. When the material touches the material lifting plate 500 at the upper end of the stirring cavity 130, the material is blocked by the material lifting plate 500 and falls from the center of the stirring cavity 130. The fallen material is stirred again by the stirring part 200, and the cycle is repeated to achieve uniform mixing.

[0044] In some embodiments, referring to Figure 2 The stirring part 200 comprises an upper paddle 210 and a lower paddle 220. The lower paddle 220 is arranged at the bottom of the stirring cavity 130, and the upper paddle 210 is arranged above the lower paddle 220. The upper paddle 210 and the lower paddle 220 are respectively connected to the stirring driving part 300 and rotate under the driving action of the stirring driving part 300. The lower paddle 220 mainly lifts the material ready for stirring to achieve better uniform stirring. The upper paddle 210 mainly provides material uniformity during mixing to make the material more uniformly stirred.

[0045] Before stirring starts, the material settles at the bottom of the stirring cavity 130. When stirring starts, under the driving action of the stirring driving part 300, the lower paddle 220 lifts the settled material in a vortex along the inner wall of the stirring cavity 130. The lifted material rotates along the inner wall of the stirring cavity 130 with the rotation of the lower paddle 220. When the material at the top of the stirring cavity 130 rotates and touches the material lifting plate 500, it falls from the center of the stirring cavity 130 and falls onto the upper paddle 210. The upper paddle 210 stirs the fallen material uniformly and then falls onto the lower paddle 220. The material falling onto the lower paddle 220 is lifted in a vortex again under the driving action of the lower paddle 220. This cycle of stirring further improves the uniformity of material mixing.

[0046] In some embodiments, referring to Figure 2 The stirring driving part 300 comprises a motor 310, a transmission belt 330, a driving wheel 320, a driven wheel 340, and a driving shaft 350. The output end of the motor 310 is drivingly connected to the driving wheel 320. The transmission belt 330 is sleeved on the outer periphery of the driving wheel 320 and the driven wheel 340. The driving shaft 350 is coaxially connected to the driven wheel 340 and extends upward. The upper end of the driving shaft 350 extends into the stirring cavity 130 and is connected to the stirring part 200.

[0047] After the motor 310 is started, the motor 310 provides rotating power to the driving wheel 320, the power is transmitted to the driven wheel 340 through the transmission belt 330, and is transmitted to the driving shaft 350 through the driven wheel 340. The driving shaft 350 rotates to drive the stirring member 200 to rotate, and the rotation of the stirring member 200 can drive the material in the stirring cavity 130 to rotate and mix.

[0048] In the embodiment, the stirring device further comprises a rack 380, and the motor 310 and the stirring drum 100 are respectively installed on the rack 380 to bear the dynamic load and static load of the motor 310 and the stirring drum 100. The rack 380 is hollow to form an installation cavity, the transmission belt 330, the driving wheel 320 and the driven wheel 340 are arranged in the installation cavity, and the rack 380 can protect the transmission assembly formed by the transmission belt 330, the driving wheel 320 and the driven wheel 340 to improve the service life of the stirring device.

[0049] The driving shaft 350 penetrates the rack 380 to be connected with the driven wheel 340 in the installation cavity. In the embodiment, the driving shaft 350 is connected with the rack 380 through a thrust bearing 360 and can rotate relative to the rack 380. In addition, the thrust bearing 360 can support the downward axial pressure.

[0050] In the embodiment, the motor 310 and the driving wheel 320 are installed as a whole, and there is no energy loss in the power transmission process; the driven wheel 340 and the driving shaft 350 are installed as a whole, and there is also no energy loss in the power transmission process; the transmission belt 330 is a V-shaped ordinary belt, the driving wheel 320 and the driven wheel 340 transmit torque through a plurality of V-shaped ordinary belts, and the transmission efficiency can reach 97%, so the torque can be efficiently output.

[0051] It can be understood that the driving shaft 350 penetrates the bottom of the stirring drum 100 and extends into the stirring cavity 130. A through hole structure is arranged at the bottom of the stirring drum 100 to facilitate the extension of the driving shaft 350. In order to avoid the material flowing out through the gap between the hole wall of the through hole structure and the outer periphery of the driving shaft 350, a sealing component 370 is arranged in the through hole structure in some embodiments.

[0052] In the embodiment, the two ends of the sealing component 370 are polytetrafluoroethylene wear-resistant rings, and the middle part is a four-layer packing seal.

[0053] In the embodiment, the stirring device further comprises a pressing member 390, and a boss structure is arranged on the outer periphery of the driving shaft 350, the lower end surface of the boss structure abuts against the bottom surface of the stirring cavity 130, and can play a certain blocking role on the upper end of the through-hole structure. The pressing member 390 is arranged at the upper end of the driving shaft 350, and the upper paddle 210 and the lower paddle 220 are arranged between the pressing member 390 and the boss structure. The pressing member 390 can fix and lock the upper paddle 210 and the lower paddle 220, so as to prevent the upper paddle 210 and the lower paddle 220 from loosening and causing damage to the equipment during stirring.

[0054] In the embodiment, the motor 310 is a variable frequency motor 310. In the early stage of stirring, the motor 310 slowly accelerates to run, so that the material gradually changes from static to dynamic. In the late stage of stirring, the motor 310 keeps high-speed running. When the stirring process is about to end, the motor 310 slowly reduces speed.

[0055] During stirring, the stirring speed is adjusted by frequency conversion in stages. When starting in the early stage, the rotating speed of the motor 310 is controlled at 50 rpm, and runs for 20 seconds. After 20 seconds, the rotating speed of the motor 310 is increased to 200 rpm, and runs for 10 seconds. Then, the rotating speed of the motor 310 is increased to 500 rpm, and runs for 10 seconds. Then, the rotating speed of the motor 310 is increased to 800 rpm, at this time, the driving shaft 350 stably runs, and the stirring member 200 stably stirs. When the set mixing time is reached, the rotating speed of the motor 310 starts to linearly reduce from 800 rpm to 0 within 20 seconds.

[0056] It can be understood that the working condition of the cooling water can be selected according to the temperature drop requirement of operation, for example, when the rotating speed of the motor 310 is high, the rotating speed of the material is high, and the heat generated by the friction between the material and the inner wall of the stirring cavity 130 is more, so that the cooling water needs to be increased.

[0057] In addition, the rotating speed of the motor 310 can also be adjusted according to the characteristics of the material, for example, when the lighter material is stirred, the rotating speed of the motor 310 can be reduced, so as to avoid the situation that the material flies to the top surface of the stirring cavity 130.

[0058] In some embodiments, the discharge port is arranged on the side wall of the stirring barrel 100 and is arranged at the lower end of the stirring barrel 100. Referring to Figure 1 , Figure 2 and Figure 3 , the stirring device further comprises a discharging assembly 600, and the automatic discharging action can be realized by arranging the discharging assembly 600.

[0059] The discharging assembly 600 comprises a discharging cylinder 610, a sealing plug 620 and a discharging driving component. The discharging cylinder 610 is provided with a discharging cavity and a discharging port 630, is installed at the discharging port of the stirring drum 100, is connected with the side wall of the stirring drum 100, and the stirring cavity 130 is communicated with the stirring cavity 130 through the discharging port. The discharging port 630 is arranged at the side wall of the discharging cylinder 610 and is communicated with the discharging cavity. The sealing plug 620 is arranged at the discharging port, and the discharging driving component is drivingly connected with the sealing plug 620. Under the driving action of the discharging driving component, the sealing plug 620 can open or close the discharging port.

[0060] In the embodiment, the discharging driving component comprises a cylinder 650 and a push rod 640. The cylinder 650 is installed at the end of the discharging cylinder 610, and the push rod 640 is arranged in the length direction of the discharging cavity. One end of the push rod 640 is connected with the cylinder 650, and the other end is connected with the sealing plug 620. Under the driving action of the cylinder 650, the push rod 640 drives the sealing plug 620 to move in the length direction of the discharging cavity, so as to open or close the discharging port.

[0061] In the embodiment, the discharging cavity is arranged in a downward inclined manner from the discharging port, and the discharging port 630 is located at the lower wall of the discharging cylinder 610.

[0062] After the stirring is completed, the cylinder 650 is started, and the sealing plug 620 is driven by the push rod 640 to move downwardly and obliquely in the discharging cavity, so that the discharging port is opened. The sealing plug 620 moves to the position where the discharging port 630 is communicated with the discharging port. The material can enter the discharging cavity from the stirring cavity 130 through the discharging port, and flow out to the downstream device through the discharging port 630.

[0063] It can be understood that, in the process of stirring, the sealing plug 620 keeps the discharging port closed under the action of the cylinder 650 and the push rod 640, so as to avoid the material flowing out of the stirring cavity 130 before the stirring is completed.

[0064] In some embodiments, the stirring drum 100 comprises a drum body 110 and an upper cover plate 120. The upper cover plate 120 is movably connected with the upper end of the drum body 110. The upper cover plate 120 and the drum body 110 jointly form the stirring cavity 130. The cooling cavity 140 is arranged in the drum wall of the drum body 110. After the upper cover plate 120 is opened, the worker can enter the stirring cavity 130 to maintain the stirring cavity 130 and the components inside the stirring cavity 130, so as to ensure the safety of the stirring device.

[0065] In some embodiments, referring to Figure 4The upper cover plate 120 and the barrel 110 are connected by the fixed buckle 121, and the barrel 110 is further provided with a turning shaft 122 at the upper end, the turning shaft 122 extends in the up-down direction, and the upper cover plate 120 is rotationally connected with the turning shaft 122. When it is necessary to overhaul the inside of the stirring cavity 130, the fixed buckle 121 is opened, and the upper cover plate 120 can be rotated around the turning shaft 122 to be flatly opened, at this time, the upper part of the stirring cavity 130 is opened, and the staff can overhaul the inside of the stirring cavity 130.

[0066] It can be understood that the movable connection between the upper cover plate 120 and the barrel 110 is realized by the above method, and the upper cover plate 120 can more conveniently open or close the stirring cavity 130. The upper cover plate 120 and the barrel 110 can also be connected by screws or other connecting members.

[0067] In some embodiments, referring to Figure 2 The stirring barrel 100 further comprises a sealing ring 170, the upper end of the barrel 110 is provided with a sealing groove, the sealing groove is provided with an opening facing upward and is located at the outer periphery of the stirring cavity 130, and the sealing ring 170 is installed in the sealing groove, and the upper end of the sealing ring 170 is connected with the lower end surface of the upper cover plate 120.

[0068] It can be understood that the sealing ring 170 can seal the gap between the upper cover plate 120 and the barrel 110, avoid the material flying out from the gap between the upper cover plate 120 and the barrel 110 during stirring, effectively prevent the environmental pollution caused by the leakage of the material dust, and avoid the influence of the flying dust on the health of the operator.

[0069] In the embodiment, the sealing ring 170 is made of silica gel material.

[0070] In some embodiments, the feeding port is arranged at the upper end of the stirring barrel 100, and a valve 800 is arranged at the feeding port. When feeding is needed, the feeding port is opened by the valve 800, and the material enters the stirring cavity 130 through the feeding port; and when the equipment is running, the feeding port is closed by the valve 800 to ensure that the material does not leak out.

[0071] In the embodiment, the valve 800 is a butterfly valve, which has the advantages of simple structure, convenient and rapid opening and closing, flexible operation, and good sealing under low pressure.

[0072] In some embodiments, the stirring device further comprises an exhaust filter 700, which is connected with the upper end of the stirring barrel 100 and is arranged in communication with the stirring cavity 130. It can be understood that the exhaust filter 700 can exhaust the gas entering the stirring cavity 130 through the feeding port, and effectively solve the problems of dust leakage during feeding and discharging and high pressure in the stirring cavity 130.

[0073] In some embodiments, a feed port flange 810 is provided at the feed port for connecting with upstream equipment to ensure normal feeding.

[0074] The stirring device can realize automatic feeding, stirring and discharging, can avoid the influence of heat generated during stirring on material properties, avoid the situation that the material sticks to the wall, and improve the material mixing and stirring efficiency and mixing effect.

[0075] Before stirring, the valve 800 is opened, the powder is fed into the stirring cavity 130 from the upstream equipment through the feed port, and is settled on the lower paddle 220 at the bottom of the stirring cavity 130, and the exhaust filter 700 exhausts the gas in the stirring cavity 130. After feeding is completed, the valve 800 is closed, and the feed port is closed. At this time, the required liquid mixture enters the stirring cavity 130 in the form of spraying through the spraying component 400, and at the same time, the motor 310 is started, and the lower paddle 220 and the upper paddle 210 stir and mix the material.

[0076] The speed of the motor 310 gradually increases, and the material rotates in a vortex under the action of the lower paddle 220 and flies to the upper part of the stirring cavity 130 until it contacts the material lifting plate 500 and falls onto the upper paddle 210. The upper paddle 210 further stirs and mixes the material, so that the material is more uniform, and the material falls onto the lower paddle 220, and the stirring is repeated.

[0077] Due to the increase of the speed of the motor 310, the speed of the material also increases, and heat energy is generated due to continuous high-speed rotation. The friction between the blade and the material and the friction between the material and the inner wall of the stirring cavity 130 will generate heat energy. A long-term overheating environment will modify the material, and some materials will even stick to the wall. At this time, cooling water is introduced into the cooling cavity 140 through the cooling water inlet 160, which can cool the stirring cavity 130, and the heat is taken away by the cooling water, thereby avoiding the modification or sticking of the material due to overheating.

[0078] After stirring is completed, the motor 310 gradually slows down until it stops running, the sealing plug 620 is opened by the push rod 640 driven by the cylinder 650 to open the discharge port, the mixed material leaves the stirring cavity 130 through the discharge port and enters the discharge cavity, and then is discharged to the downstream equipment through the discharge port 630.
