Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, and in particular to a stirring device for uniformly mixing heat insulation material particles. Background Technology

[0002] Thermal insulation materials are typically composed of various particles with different components, such as ceramic particles, glass fibers, and organic fibers. Due to the differences in the shape, size, density, and other physical properties of these particles, a mixing and stirring device is needed to mix these various thermal insulation material particles to ensure uniform mixing and overall thermal insulation performance.

[0003] Mixing and stirring devices are used to mix materials, and mixing and stirring devices for modified plastic granules are one type. However, most of the previous mixing and stirring devices for modified plastic granules were inefficient and could not efficiently mix the modified plastic granules, which reduced the user experience and failed to meet the needs of today's market. Due to the above problems, the practicality and usability of mixing and stirring devices for modified plastic granules were reduced. Therefore, a uniform and efficient mixing and stirring device for modified plastic granules was specifically launched.

[0004] An existing patent (publication number: CN214163602U) discloses a uniform and efficient mixing device for modified plastic granules. This utility model achieves high efficiency through the cooperation of a base plate, a first vertical plate, a second vertical plate, a first rotating rod, a first gear, a first motor, a second rotating rod, a second gear, a housing, a horizontal tube, a stirring rod, a stirring blade, a third gear, a second motor, and a fourth gear. It can efficiently mix modified plastic granules, improve the user experience of the mixing device for modified plastic granules, and meet the needs of today's market.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when existing mixing devices mix various thermal insulation material particles together, they add all the particles into the mixing tank through the feeding hopper. This results in the particles not being pre-dispersed, which naturally affects the efficiency and uniformity of subsequent mixing. Furthermore, the feeding process cannot be intermittent, leading to uneven mixing caused by the raw materials entering the mixing tank all at once.

[0006] To address this, a device for uniformly mixing and stirring thermal insulation material particles is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a uniform mixing and stirring device for thermal insulation material particles. This device can solve the problems of existing mixing and stirring devices, which add multiple thermal insulation material particles into the mixing tank at the same time through the feeding hopper. This results in the particles not being pre-dispersed, which naturally affects the efficiency and uniformity of subsequent mixing. In addition, the feeding process cannot be intermittent, which leads to uneven mixing caused by the raw materials entering the mixing tank all at once.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for uniformly mixing and stirring thermal insulation material particles, comprising a mixing tank, a feeding hopper connected to the top of the mixing tank, a material control mechanism provided inside the feeding hopper, a stirring mechanism provided inside the mixing tank, and a discharge valve connected to the bottom of the mixing tank;

[0009] The stirring mechanism includes a motor bolted to the bottom of the stirring tank, the output end of the motor penetrating through the bottom of the stirring tank, a circular frame fixedly connected to the top of the inside of the stirring tank, a dispersing net fixedly connected to the bottom of the circular frame, a shaft fixedly connected to the output end of the motor, the top of the shaft penetrating through the bottom of the dispersing net, a dispersing rod bolted to the top of the shaft, the dispersing rod being located at the top of the dispersing net, and a stirring rod provided on the outside of the shaft.

[0010] Preferably, the material control mechanism includes inclined plates fixedly connected to both sides inside the feeding hopper, and material control plates are provided on both sides of the bottom side inside the feeding hopper, with the material control plates located at the bottom of the inclined plates.

[0011] Preferably, electric telescopic rods are bolted to both sides of the feeding hopper, the telescopic ends of the electric telescopic rods penetrate through the outer side of the feeding hopper, and the telescopic ends of the electric telescopic rods are bolted to the outer side of the material control plate.

[0012] Preferably, a controller is provided on the right side of the mixing tank, and the controller is electrically connected to the electric telescopic rod.

[0013] Preferably, a fixing rod is fixedly connected inside the circular frame, and the fixing rod is located at the top of the dispersing net.

[0014] Preferably, auxiliary stirring rods are fixedly connected to both sides of the bottom of the dispersing net, and coarse flow holes are opened on the surface of the auxiliary stirring rods.

[0015] Preferably, the surface of the stirring rod is provided with a diversion hole, which is a circular groove shape.

[0016] Preferably, a bottom stirring rod is fixedly connected to the bottom of the stirring rod, and the bottom stirring rod is located on the bottom side inside the mixing tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application uses a stirring mechanism where a motor drives a shaft to rotate, causing a dispersing rod to pre-disperse various heat insulation material particles entering the top of the dispersing net, effectively eliminating particle agglomeration. The dispersed particles then fall into the mixing tank through the dispersing net, while the stirring rod stirs the dispersed particles, effectively improving the stirring efficiency and uniformity.

[0019] 2. By setting up a material control mechanism, the feeding frequency of the insulation material particles can be adjusted to intermittent feeding when they are added to the feeding hopper. This avoids the problems of local overload or uneven stirring resistance caused by the one-time influx of raw materials in traditional devices. Combined with the pre-dispersion mechanism of the stirring mechanism, the stability of the stirring process and the mixing effect are further guaranteed. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A device for uniformly mixing and stirring thermal insulation material particles includes a mixing tank 1, a feeding hopper 2 connected to the top of the mixing tank 1, a material control mechanism 3 provided inside the feeding hopper 2, a stirring mechanism 4 provided inside the mixing tank 1, and a discharge valve 5 connected to the bottom of the mixing tank 1.

[0029] The stirring mechanism 4 includes a motor 41 bolted to the bottom of the stirring tank 1. The output end of the motor 41 passes through the bottom of the stirring tank 1. A circular frame 42 is fixedly connected to the top inside the stirring tank 1. A dispersing net 43 is fixedly connected to the bottom of the circular frame 42. A shaft 44 is fixedly connected to the output end of the motor 41. The top of the shaft 44 passes through the bottom of the dispersing net 43. A dispersing rod 45 is bolted to the top of the shaft 44. The dispersing rod 45 is located at the top of the dispersing net 43. A stirring rod 46 is provided on the outside of the shaft 44.

[0030] In this embodiment: By setting up a material control mechanism 3 and a stirring mechanism 4, the heat insulation material particles are added from the feeding hopper 2. The material control mechanism 3 plays a role in adjusting the feeding frequency of the heat insulation material particles to intermittent feeding, avoiding a large amount of raw materials flowing into the mixing tank 1 at once, and preventing problems such as local overload or uneven stirring resistance. At the same time, the motor 41 is started, and the motor 41 drives the shaft 44 to rotate. The dispersing rod 45 at the top of the shaft 44 rotates accordingly, pre-dispersing the various heat insulation material particles entering the top of the dispersing net 43, effectively eliminating particle agglomeration. The dispersed particles fall into the mixing tank 1 through the dispersing net 43. At this time, the stirring rod 46 on the outside of the shaft 44 stirs the falling particles, improving the stirring efficiency and uniformity. After stirring is completed, the discharge valve 5 is opened to discharge the mixed heat insulation material particles.

[0031] Specifically, such as Figure 3 As shown, the material control mechanism 3 includes inclined plates 31 fixedly connected to both sides inside the feeding hopper 2, and material control plates 32 are provided on both sides of the bottom inside the feeding hopper 2. The material control plates 32 are located at the bottom of the inclined plates 31.

[0032] Specifically, such as Figure 3 As shown, electric telescopic rods 33 are bolted to both sides of the feeding hopper 2. The telescopic ends of the electric telescopic rods 33 penetrate through the outside of the feeding hopper 2, and the telescopic ends of the electric telescopic rods 33 are bolted to the outside of the material control plate 32.

[0033] Specifically, such as Figure 3 As shown, a controller 34 is provided on the right side of the mixing tank 1, and the controller 34 is electrically connected to the electric telescopic rod 33.

[0034] In this embodiment: by setting up a material control mechanism 3, when the heat insulation material particles are added to the feeding hopper 2, the particles slide down the inclined plate 31. The operator can control the extension and retraction of the electric telescopic rod 33 through the controller 34. The extension and retraction end of the electric telescopic rod 33 drives the material control plate 32 to move. When the electric telescopic rod 33 extends, the material control plate 32 closes to prevent the particles from falling. When the electric telescopic rod 33 retracts, the material control plate 32 opens and the particles fall, thereby realizing intermittent feeding, avoiding the raw materials from entering the mixing tank 1 in large quantities at one time, and ensuring uniform mixing.

[0035] Specifically, such as Figure 5 As shown, a fixing rod 6 is fixedly connected inside the circular frame 42, and the fixing rod 6 is located at the top of the dispersing net 43.

[0036] Specifically, such as Figure 4 As shown, auxiliary stirring rods 7 are fixedly connected to both sides of the bottom of the dispersing net 43, and coarse flow holes 8 are opened on the surface of the auxiliary stirring rods 7.

[0037] In this embodiment: by setting a fixed rod 6, an auxiliary stirring rod 7 and a coarse flow hole 8, the fixed rod 6 inside the circular frame 42 enhances the stability of the dispersing net 43, making it less prone to shaking when the dispersing rod 45 is working. After the heat insulation material particles are dispersed, they pass through the dispersing net 43. The auxiliary stirring rod 7 at the bottom of the dispersing net 43 rotates with the shaft 44, further stirring the heat insulation material particles in the mixing tank 1. The coarse flow hole 8 on the surface of the auxiliary stirring rod 7 allows the particles to pass through more smoothly, and at the same time, it disrupts the movement trajectory of the particles to a certain extent, improving the stirring effect.

[0038] Specifically, such as Figure 4 As shown, the surface of the stirring rod 46 is provided with a flow divider hole 9, which is a circular groove shape.

[0039] Specifically, such as Figure 4 As shown, a bottom stirring rod 10 is fixedly connected to the bottom of the stirring rod 46, and the bottom stirring rod 10 is located on the bottom side inside the stirring tank 1.

[0040] In this embodiment: by setting the diversion hole 9 and the bottom stirring rod 10, when the stirring rod 46 rotates and stirs, the diversion hole 9 on its surface can disperse and flow the particles during the stirring process, increase the contact and mixing opportunities between particles, and improve the stirring uniformity. In addition, the bottom stirring rod 10 at the bottom of the stirring rod 46 is located on the bottom side inside the stirring tank 1, which can stir the particles that have settled at the bottom, avoid the accumulation of particles at the bottom, and ensure that the particles in the entire stirring tank 1 can be fully mixed.

[0041] Working Principle: During the use of the heat insulation material granule uniform mixing device, the heat insulation material granules are first added from the feeding hopper 2. The granules slide down the inclined plate 31. The operator controls the extension and retraction of the electric telescopic rod 33 via the controller 34 on the right side of the mixing tank 1. The extension and retraction of the electric telescopic rod 33 drives the control plate 32 to move. When the electric telescopic rod 33 extends, the control plate 32 closes, preventing the granules from falling. When the electric telescopic rod 33 retracts, the control plate 32 opens, allowing the granules to fall. This achieves intermittent feeding, avoiding a large influx of raw materials into the mixing tank 1 at once, preventing local overload or uneven mixing resistance. Simultaneously, the motor 41 at the bottom of the mixing tank 1 is started. The motor 41 drives the shaft 44 to rotate, and the dispersing rod 45 at the top of the shaft 44 rotates accordingly, pre-dispersing the various heat insulation material granules entering the top of the dispersing net 43, effectively eliminating particle agglomeration. The fixing rod 6 inside the circular frame 42 enhances the... The stability of the dispersing net 43 prevents it from shaking when the dispersing rod 45 is working. After being dispersed, the particles pass through the dispersing net 43. The auxiliary stirring rods 7 on both sides of the bottom of the dispersing net 43 rotate with the shaft 44, further stirring the heat insulation material particles. The coarse flow holes 8 on the surface of the auxiliary stirring rods 7 allow the particles to pass through more smoothly, while disrupting the movement trajectory of the particles and improving the stirring effect. After the particles fall into the mixing tank 1, the stirring rod 46 on the outside of the shaft 44 begins to stir them. The circular diversion holes 9 on the surface of the stirring rod 46 can disperse and flow the particles during the stirring process, increasing the contact and mixing opportunities between the particles and improving the uniformity of the stirring. The bottom stirring rod 10 at the bottom of the stirring rod 46 is located inside the bottom of the mixing tank 1 and can stir the particles that have settled at the bottom, preventing the particles from accumulating at the bottom and ensuring that all the particles in the mixing tank 1 are fully mixed. After the stirring is completed, the discharge valve 5 at the bottom of the mixing tank 1 is opened to discharge the mixed heat insulation material particles.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
