Description

Technical Field

[0001] The utility model relates to the technical field of wallboard raw material processing devices, in particular to a stirring device. Background Art

[0002] Bamboo fiber wall panels are a new type of environmentally friendly wall panels. Their production process is to use bamboo wood powder, stone powder and plastic powder to press integrated wall panels. They do not contain harmful substances such as formaldehyde, meet national environmental protection standards, and are harmless to human health. They are environmentally friendly, beautiful, durable, sound-insulating, heat-insulating, fire-retardant wall panels with many advantages. During production, the raw materials need to be stirred.

[0003] However, when the existing raw material stirring devices for the production of bamboo and wood fiber decorative wall panels are used, most of them use a motor to drive the stirring shaft and the stirring rod to rotate, thereby stirring the raw materials. The stirring rod can only stir the middle part of the stirring box, which not only makes the stirring efficiency low and the effect poor, but also makes the raw materials easily adhere to the inner wall of the stirring box, which not only affects the stirring effect but also easily causes raw materials to be wasted. Utility Model Content

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a stirring device to solve the problem that raw materials easily adhere to the inner wall of the stirring box, resulting in poor stirring effect.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A stirring device comprises a stirring drum, wherein a cover plate is provided at the upper end of the stirring drum, a motor is fixedly mounted on the cover plate, a shaft is fixedly connected to the output shaft of the motor, the shaft rod passes through the cover plate into the stirring drum, a middle stirring piece, a bottom stirring piece and a side stirring piece are provided on the shaft rod located inside the stirring drum, and a conveying mechanism is provided at the bottom of the stirring drum.

[0007] Through the above scheme, different stirring components (middle stirring component, bottom stirring component and side stirring component) are installed on the shaft, which can achieve full mixing of materials at different levels and directions, improve stirring uniformity, and accelerate the mixing speed of powder. A conveying mechanism is provided at the bottom of the mixing drum, which facilitates the discharge of materials after stirring, simplifies the unloading process, and improves work efficiency.

[0008] Furthermore, a vent is provided on the cover plate, a sealing cover is provided on the cover plate at the vent, an air hole is provided on the sealing cover, a hole plug is provided in the air hole, and a filter cartridge is provided in the vent.

[0009] Through the above-mentioned further scheme, when feeding or discharging materials into the mixing drum, exhaust or air intake can be carried out through the vents on the cover or the air holes on the cover, so as to prevent a large difference between the pressure inside the mixing drum and the external pressure, which may cause a safety hazard. At the same time, proper air intake and exhaust can also help maintain temperature control during the mixing process. The filter cartridge can filter the exhausted gas to avoid a large amount of dust in the exhausted gas, thereby reducing the impact on the environment.

[0010] Furthermore, a plurality of feed pipes are provided on the cover plate.

[0011] According to the above further solution, a variety of different raw materials can be added to the mixing drum at the same time or as needed through different feeding pipes, which can increase the mixing rate of the raw materials.

[0012] Furthermore, the middle stirring member includes a middle mounting shaft, multiple middle stirring blades and a connecting ring. The middle mounting shaft is fixedly installed in the middle of the shaft rod. One end of the multiple middle stirring blades is evenly arranged and installed on the outside of the middle mounting shaft, and the other end is connected to the connecting ring.

[0013] Through the above-mentioned further scheme, multiple middle stirring blades are evenly arranged on the middle mounting shaft and connected to each other through connecting rings to form a relatively solid overall structure, which can ensure that the stirring blades can effectively cut the material flow during rotation and promote sufficient contact and mixing between materials. The middle stirring piece is located in the center of the mixing drum, which can better drive the surrounding materials to circulate and thus accelerate mixing.

[0014] Furthermore, the middle stirring blade is provided with a plurality of holes, and the middle stirring blade is curved.

[0015] Through the above-mentioned further solution, the holes allow part of the material to pass through the mixing blades instead of being pushed aside. This "penetration" effect can enable the material to exchange between different layers, improving the uniformity of material distribution and the degree of mixing in the entire mixing drum. The curved mixing blades can create more turbulent areas, further increasing the contact opportunities between materials and making the mixing more thorough.

[0016] Furthermore, the bottom stirring member includes a bottom mounting shaft and a plurality of bottom stirring blades, the bottom mounting shaft is fixedly mounted on the connecting ends of the shaft rod and the motor output shaft, and the plurality of bottom stirring blades are evenly arranged and mounted on the outer side of the bottom mounting shaft.

[0017] Through the above further solution, the bottom stirring blades are designed specifically for the material at the bottom of the mixing drum, which helps to prevent the material from settling at the bottom or forming dead corners, ensuring that even the material at the bottom of the mixing drum can be effectively turned and mixed.

[0018] Furthermore, a brush rod is provided on the bottom side of the bottom stirring blade, and beveled edges are provided on both sides of the brush rod. The shape of the bottom side of the brush rod is adapted to the shape of the bottom of the mixing drum.

[0019] Through the above-mentioned further solution, the brush rod can fit tightly to the bottom of the mixing drum, effectively remove the material deposited at the bottom, help prevent the material from adhering or agglomerating, ensure that the bottom of the mixing drum remains clean after each mixing, and can minimize material residue, improve material utilization, and thus reduce production costs.

[0020] Furthermore, the side stirring member includes an upper mounting shaft, a lower mounting shaft, multiple upper stirring blades, multiple lower stirring blades and multiple brush plates, the upper mounting shaft and the lower mounting shaft are fixedly mounted on the shaft rod, the upper mounting shaft and the lower mounting shaft are respectively located on the upper and lower sides of the middle stirring member, the upper stirring blades, the lower stirring blades and the brush plates are the same in number, the multiple upper stirring blades are evenly arranged and mounted on the upper mounting shaft, the multiple lower stirring blades are evenly arranged and mounted on the lower mounting shaft, the brush plates are connected to the upper stirring blades and the lower stirring blades, and inclined surfaces are provided on both sides of the brush plates.

[0021] Through the above-mentioned further scheme, the brush plate is attached to the inner wall of the mixing drum, and the upper stirring blade and the lower stirring blade are respectively located on the upper and lower sides of the middle stirring piece, so that the material can be stirred at different heights to ensure that the material in the entire mixing drum can be fully mixed. The brush plate is connected to the upper stirring blade and the lower stirring blade to form a whole. The brush plate can effectively scrape off the material adhering to the inner wall of the mixing drum, and the material in the edge area of the mixing drum can also be fully stirred to avoid the formation of dead corners.

[0022] Furthermore, the conveying mechanism includes a discharge pipe, a conveying pump and a connecting pipe. A discharge port is provided at the bottom of the mixing drum. One end of the connecting pipe is connected to the discharge port, and the other end is connected to the feed end of the conveying pump. The discharge end of the conveying pump is connected to one end of the discharge pipe.

[0023] Through the above further solution, by using a conveying pump, the mixed material can be quickly and effectively conveyed from the discharge port at the bottom of the mixing drum to the discharge pipe, which not only speeds up the discharge speed but also ensures the continuity and stability of the discharge process.

[0024] In summary, the stirring device provided by the present invention has the following technical effects:

DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example:

[0038] refer to Figure 1 and Figure 2 As shown, a stirring device includes a stirring drum 1, which is fixedly mounted on a base. A cover plate 11 is provided on the upper end of the stirring drum 1. The cover plate 11 can prevent materials from splashing during the stirring process, ensure the cleanliness of the operating environment, and reduce the waste of raw materials.

[0039] Among them, three feeding pipes 116 are provided on the cover plate 11, which are used to add bamboo powder, stone powder and plastic powder respectively. Through the three feeding pipes 116, a variety of different raw materials can be added to the mixing drum 1 at the same time or as needed, which can increase the mixing rate of the raw materials.

[0040] As a further development of this embodiment, each feed pipe 116 can be individually equipped with flow meters, valves and other control equipment, making it possible to accurately control the input amount of various raw materials. In addition, this also provides a basis for realizing automated control, such as using a PLC (programmable logic controller) to manage the entire feeding process.

[0041] Among them, reference figure Figure 2As shown, a vent 111 is provided on the cover plate 11, a sealing cover 112 is provided on the cover plate 11 at the vent 111, an air hole 113 is provided on the sealing cover 112, a hole plug 114 is provided in the air hole 113, and a filter cartridge 115 is provided in the air vent 111. When feeding or discharging the mixing drum 1, exhaust or air intake can be carried out through the vent 111 on the cover plate 11 or the air hole 113 on the sealing cover 112 to prevent a large difference between the pressure in the mixing drum 1 and the external pressure, which may cause a safety hazard. At the same time, proper air intake and exhaust can also help maintain temperature control during the mixing process. The filter cartridge 115 can filter the exhausted gas to avoid a large amount of dust in the exhausted gas, reduce the impact on the environment, and required substances can also be added through the vent 111.

[0042] It should be noted that when the exhaust or air intake demand of the mixing drum 1 is large, the cover 112 is opened and the gas is circulated through the vent 111. When the exhaust or air intake demand of the mixing drum 1 is small, the cover 112 is closed, the hole plug 114 is removed, and the air hole 113 is opened to realize the circulation of gas and control the size of the gas circulation, which can prevent the gas from carrying a large amount of dust into the air.

[0043] refer to Figure 3 and Figure 4 As shown, a motor 2 is fixedly mounted on the cover plate 11, and a shaft 21 is fixedly connected to the output shaft of the motor 2. The shaft 21 passes through the cover plate 11 to the mixing drum 1, and a middle mounting shaft 31 is fixedly mounted in the middle of the shaft 21. A plurality of middle stirring blades 32 are evenly arranged and mounted on the outer side of the middle mounting shaft 31. The middle stirring blades 32 and the middle mounting shaft 31 are connected end to end with connecting rings 33, thereby forming a relatively solid overall structure, which can ensure that the stirring blades can effectively cut the material flow during rotation and promote sufficient contact and mixing between materials. The middle stirring element 3 is located in the center of the mixing drum 1, which can better drive the surrounding materials to circulate, thereby accelerating mixing. Since the stirring blades are connected by the connecting ring 33, this increases the stability of the entire stirring element and reduces the risk of affecting the overall stirring effect due to deformation or damage of a single blade.

[0044] Among them, a plurality of holes 321 are provided on the middle stirring blade 32, and the middle stirring blade 32 is curved. The holes 321 allow part of the material to pass through the stirring blade instead of just being pushed aside. This "penetration" effect can enable the material to be exchanged between different layers, thereby improving the uniformity of material distribution and the mixing degree of the material in the entire mixing drum 1. The curved stirring blade can create more turbulent areas, further increase the contact opportunities between materials, and make the mixing more thorough.

[0045] refer to Figure 3 and Figure 4As shown, a bottom mounting shaft 41 is fixedly mounted on the end-to-end connection between the shaft 21 and the output shaft of the motor 2, and a plurality of bottom stirring blades 42 are evenly arranged and mounted on the outer side of the bottom mounting shaft 41. The design of the bottom stirring blades 42 is specifically for the material at the bottom of the mixing drum 1, which helps to prevent the material from settling at the bottom or forming a dead angle, ensuring that even the material at the bottom of the mixing drum 1 can be effectively turned and mixed.

[0046] Among them, a brush rod 421 is provided on the bottom side of the bottom stirring blade 42, and a bevel 422 is provided on both sides of the brush rod 421. The shape of the bottom side of the brush rod 421 is adapted to the shape of the bottom of the mixing drum 1. The brush rod 421 can fit tightly to the bottom of the mixing drum 1, effectively remove the material deposited at the bottom, help prevent the material from adhering or agglomerating, ensure that the bottom of the mixing drum 1 remains clean after each stirring, and can minimize material residue, improve material utilization, and thus reduce production costs. The brush rod 421 can also effectively remove the material at the bottom of the mixing drum 1, reducing the need for regular manual cleaning and simplifying daily maintenance work.

[0047] As a further development of this embodiment, the cross bar on the bottom stirring blade 42 is designed to have a specific tilt angle to generate an upward thrust, causing the bottom material to move upward. This flow pattern helps to break up the layered structure, enhance the turbulence effect during the entire stirring process, and further improve the mixing effect.

[0048] refer to Figure 3 and Figure 4 As shown, an upper mounting shaft 51 and a lower mounting shaft 52 are respectively provided on the upper and lower sides of the middle stirring member 3 on the shaft rod 21, and a plurality of upper stirring blades 53 are evenly arranged and installed on the outer side of the upper mounting shaft 51, and a plurality of lower stirring blades 54 are evenly arranged and installed on the outer side of the lower mounting shaft 52. Brush plates 55 are connected to the upper stirring blades 53 and the lower stirring blades 54. The number of upper stirring blades 53, lower stirring blades 54 and brush plates 55 is the same. The upper stirring blades 53 and the lower stirring blades 54 are respectively located on the upper and lower sides of the middle stirring member 3, and the materials can be stirred at different heights to ensure that the materials in the entire mixing drum 1 can be fully mixed. The brush plates 55 are connected to the upper stirring blades 53 and the lower stirring blades 54 to form a whole, which not only enhances the mixing effect in the central area, but also optimizes the material flow in the edge area, thereby improving the overall mixing efficiency.

[0049] The brush plate 55 is close to the inner wall of the mixing drum 1 , and the brush plate 55 can effectively scrape off the material adhering to the inner wall of the mixing drum 1 , and the material in the edge area of the mixing drum 1 can also be fully stirred to avoid the formation of dead corners.

[0050] Among them, both sides of the brush plate 55 are provided with inclined surfaces, which enable the brush plate 55 to scrape off materials adhering to the wall surface more effectively, reducing the workload of cleaning and maintenance.

[0051] refer to Figure 1 and Figure 5 As shown, a discharge port 12 is provided at the bottom of the mixing drum 1, the discharge port 12 is connected to one end of a connecting pipe 63, the other end of the connecting pipe 63 is connected to the feed end of a delivery pump 62, the discharge end of the delivery pump 62 is connected to a discharge pipe 61, and the discharge pipe 61 and the delivery pump 62 are connected end to end to the feed end of the extruder. The delivery pump 62 is fixedly mounted on the base and is located next to the mixing drum 1. By using the delivery pump 62, the mixed material can be quickly and effectively transported from the discharge port 12 at the bottom of the mixing drum 1 to the discharge pipe 61, which not only speeds up the discharging speed, but also ensures the continuity and stability of the discharging process.

[0052] As a further development of this embodiment, the configuration of the delivery pump 62 and the pipeline system can be adjusted according to actual production needs, such as replacing different types of pump heads or adjusting the pipeline size to adapt to different material properties and output requirements. A valve is set on the connecting pipe 63 to control the opening and closing of the connecting pipe 63, and can be controlled by a PLC (programmable logic controller), laying the foundation for full automation.

[0053] The working principle of this utility model is:

[0054] Through the feed pipe 116, bamboo powder, stone powder and plastic powder are added into the mixing drum 1 respectively. During this period, the vent 111 or the air hole 113 is opened, and the motor 2 is started. The motor 2 drives the bottom stirring blade 42, the middle stirring blade 32, the upper stirring blade 53 and the lower stirring blade 54 to stir and mix the raw materials. The brush rod 421 and the brush plate 55 on the bottom stirring blade 42 can scrape off the materials adhering to the bottom and sides of the mixing drum 1. After the mixing is completed, the delivery pump 62 is started, and the delivery pump 62 discharges the mixed raw materials through the discharge pipe 61.
