Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a stirring device that is easy to install and maintain. Background Technology

[0002] In industries such as chemical, food, and building materials, mixing devices are widely used due to their high mixing efficiency and continuous operation capabilities. Traditional mixing devices typically employ a welded integral structure, where the tank and base are fixed together by welding. While this ensures structural stability, it suffers from the following significant drawbacks:

[0003] Maintenance is difficult: Components inside the tank, such as the mixing shaft and impellers, are prone to wear and tear or residue buildup due to prolonged contact with materials, requiring regular cleaning and maintenance. However, the welded structure forces maintenance personnel to enter the tank through narrow manholes, resulting in incomplete cleaning and extremely low efficiency in spare parts replacement. For medium-sized equipment with a volume greater than 2m³, maintenance can take more than 48 hours.

[0004] Disassembly costs are high: If a thorough overhaul of the tank's interior or replacement of the main shaft bearing is required, the welded joints must be cut and removed. For example, a building materials company would need to invest approximately 30,000 yuan in cutting / re-welding costs to disassemble a 270,000 yuan piece of equipment, and the re-welded structure would pose safety risks. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a stirring device that is easy to install and maintain, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, one embodiment of the present invention provides a mixing device that is easy to install and maintain, including a base, a fixing plate, a tank, a feed inlet, and a discharge outlet. The top of the base is detachably connected to several fixing plates, and the tank is fixedly connected between the fixing plates. The top of the tank is fixedly connected to the feed inlet, and the bottom of the tank is fixedly connected to the discharge outlet.

[0008] The discharge port passes through the base from top to bottom. A transmission unit is fixedly connected to the end of the tank. A reduction motor is fixedly connected to the top of the base. The transmission unit has a built-in belt drive mechanism.

[0009] The tank is internally connected to a main shaft, and the geared motor is linked to the main shaft via a belt drive mechanism.

[0010] Several stirring rods are fixedly connected to the outer surface of the main shaft, and a fan-shaped stirring head is fixedly connected to the outer end of each stirring rod;

[0011] The top of the base is fixedly connected with several pins, which are inserted into a fixing plate from bottom to top. A pressure claw is movably connected to the surface of the fixing plate, and the bottom surface of the pressure claw also presses against the top surface of the base. A crossbeam is fixedly connected to the end of the pressure claw, and the crossbeam is inserted into the gap on the side of the base.

[0012] The base is fixedly connected to a connector on its side. The connector is inserted into the crossbeam, and a fastening head is threaded to the end of the connector. The fastening head is tightened onto the surface of the crossbeam.

[0013] Preferably, in any of the above solutions, the base is I-shaped and is welded to the tank body.

[0014] The above technical solution is adopted: This device is a stirring device. The material enters the tank through the feed port. When the reduction motor is working, the pulley connected to the output end of the motor drives the belt to rotate. The belt drives the pulley at the end of the main shaft to rotate, thereby driving the main shaft to rotate. The stirring rod and stirring head stir the material, and finally output it through the discharge port.

[0015] The tank body is fixed between the fixing plates. The tank body and the base are not directly welded together, but rather assembled, allowing for quick assembly and disassembly. This allows the tank body to be lifted away after separation from the base, facilitating comprehensive inspection, maintenance, and internal cleaning.

[0016] The fixing plate is first installed on the base, and then the fixing plate is fitted onto the pin. After initial positioning, the crossbeam is fitted onto the connector from the side of the base. The pressure claw is movably connected to the bottom surface of the fixing plate, and the pressure claw repositions the fixing plate. After the crossbeam is in place, multiple fastening heads are tightened to achieve quick mounting of the mixing tank. The entire installation of the mixing tank can be achieved with fewer connecting mechanisms, and the disassembly and separation of the mixing tank from the base is also relatively quick and simple.

[0017] Preferably, in any of the above embodiments, the transmission unit includes a housing connected to the end of the tank, a pulley connected to the end of the main shaft, another pulley connected to the output end of the geared motor, and a belt movably connected to the surface of the pulleys.

[0018] The above technical solution is adopted as follows: Foundation and support: The base constitutes the basic support structure of the device, and is preferably designed as an I-beam structure to provide good stability and load-bearing capacity.

[0019] Several fixing plates are mounted on top of the base. These plates are not welded or permanently fixed to the base, but are detachably connected. The fixing plates are connected to the tank by welding or other secure methods, collectively providing support and stability for the tank.

[0020] A feed inlet is fixedly installed at the top of the tank for material input. A discharge outlet is fixedly installed at the bottom of the tank for material output after mixing. The discharge outlet passes through a pre-drilled hole on the base from top to bottom.

[0021] Power and transmission: The geared motor is fixedly mounted on the top of the base. This is the power source for the device.

[0022] The transmission unit is fixedly connected to the end of the tank (usually the drive end away from the geared motor). The transmission unit contains a belt drive mechanism. This mechanism typically includes: a main pulley (A) fixed to the transmission unit housing (usually the housing is fixed to the end of the tank) for connecting to and driving the main shaft; a secondary pulley (B) connected to the output shaft of the geared motor; and a belt wrapped around the surfaces of pulleys A and B for transmitting power.

[0023] The main shaft is movably connected inside the tank, with its end (drive end) extending into the transmission unit and connecting to an internal pulley. The geared motor drives the main shaft to rotate via its output pulley and belt drive mechanism (located inside the transmission unit).

[0024] Stirring component: Multiple stirring rods are fixedly connected to the outer surface of the main shaft. Preferably, the root of the stirring rod is connected to the main shaft by riveting to ensure strength.

[0025] Each stirring rod has a fan-shaped stirring head fixedly connected to its outer end. Preferably, the stirring rod and the fan-shaped stirring head are connected by screws. The fan-shaped design helps to improve stirring efficiency and reduce resistance.

[0026] Quick assembly and disassembly mechanism (core advantage):

[0027] Several pins are fixedly installed on the top of the base. During installation, the bottom of the fixing plate is pre-drilled with corresponding holes so that it can be fitted onto the pins from bottom to top, thus achieving the initial positioning of the tank assembly (including the fixing plate and the tank) on the base.

[0028] Each fixed plate has a pressure claw (e.g., via a pivot connection) movably connected to its surface. One working surface of the pressure claw is located below the fixed plate.

[0029] The bottom surface (i.e. the working surface) of the pressure claw has a downward pressing function, and the bottom surface eventually presses against the top surface of the base.

[0030] A crossbeam is fixedly connected to the end of the pressure claw (the end opposite to the end of the connecting fixing plate). The pressure claw and the crossbeam are preferably connected by welding. After installation, the crossbeam snaps into a specific gap or groove on the side of the base.

[0031] The base has a connector fixedly attached to its side. When the crossbeam is inserted into the gap on the side of the base, the connector passes through or is inserted into a pre-set hole on the crossbeam.

[0032] The end of the connector (typically the portion extending beyond the crossbeam) is provided with external threads, forming a threaded connection with the fastening head. The fastening head is preferably a washered nut. By tightening the fastening head, its washer is pressed tightly against the surface of the crossbeam, thereby pulling the crossbeam and the connected pressure claw downwards. After the pressure claw is pressed down, its bottom surface applies a downward force, firmly pressing the fixing plate against the top surface of the base, while simultaneously pressing the bottom surface of the pressure claw itself firmly onto the base, thus achieving final locking and positioning of the tank assembly on the base. A rubber gasket can be provided on the bottom surface of the pressure claw to increase friction and prevent slippage and wear.

[0033] Preferably, in any of the above embodiments, the main shaft is riveted to the root of the stirring rod, and the stirring rod is connected to the stirring head by screws.

[0034] The working process of this device is as follows: During the mixing process, the material enters the tank through the inlet. When the geared motor is started, its output drives the pulley to rotate. This pulley, through a belt inside the transmission unit, drives the main pulley connected to the end of the main shaft to rotate. The main pulley drives the main shaft to rotate within the tank. The stirring rod and fan-shaped stirring head, fixedly mounted on the main shaft, rotate together with the main shaft, thoroughly and efficiently mixing the material inside the tank. The mixed material is then discharged from the outlet at the bottom of the tank under the action of gravity or the discharge mechanism.

[0035] Assembly Process (Quick Installation): First, hoist the tank assembly (including the main shaft, stirring rod, stirring head, transmission housing, etc.) with the welded fixing plate onto the base. Initial positioning is achieved using pins, allowing the pins to fit into the holes at the bottom of the fixing plate, thus initially placing the tank assembly on the base. Next, operate the clamping claws to insert the connected crossbeam into the gap on the side of the base. Then, insert the connectors into the corresponding holes on the crossbeam. Finally, tighten the fastening heads (with washer nuts) at the ends of each connector thoroughly. The tightening process causes the fastening heads to press down on the crossbeam, which, through the clamping claws, firmly presses the fixing plate and tank assembly onto the base. The entire installation process requires only the operation of a few fastening heads, making it very quick.

[0036] Disassembly Process (Quick Maintenance): When a comprehensive overhaul, cleaning, or maintenance of internal parts such as the main shaft is required, the operation is extremely simple: just loosen and remove all fasteners. After releasing the fasteners, the crossbeam along with the pressure claws can be easily moved away from the joint and base. At this point, the fixing plate loses the downward pressure of the pressure claws, and the tank assembly (along with the fixing plate) can be lifted upwards to remove it from the pins. After disassembly, the tank can be lifted off the base as a whole, providing ample operating space for comprehensive overhaul, maintenance, internal cleaning, or replacement of parts. After maintenance, it can be quickly reassembled and put back into use following the assembly process described above.

[0037] While ensuring stable installation, the device offers high maintainability: the tank and base are connected by a non-welded, detachable structure (pins, clamps, crossbeams, connectors, and fasteners), allowing for quick separation of the tank and base during maintenance. After separation, the tank can be lifted away as a whole, providing ample operating space and greatly facilitating internal inspection, cleaning, maintenance, and replacement of internal parts such as the main shaft and agitator.

[0038] Easy installation and disassembly: The entire assembly and disassembly process is simple and quick, with the main operations being only tightening and loosening a small number of fasteners (nuts) and adjusting the crossbeam, which significantly reduces the maintenance time and operational difficulty of the equipment.

[0039] Preferably, in any of the above embodiments, the bottom surface of the pressure claw has a rubber pad, and the pressure claw is welded to the crossbeam.

[0040] Preferably, from any of the above solutions, the fastening head is a washer-type nut.

[0041] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0042] This easy-to-install and maintain mixing device, under the premise of ensuring stable installation, has the tank fixed between the fixing plates. The tank and the base are not directly welded, but assembled, which can be quickly assembled and disassembled. After the tank is separated from the base, the tank can be lifted away, which makes it relatively convenient to carry out a comprehensive inspection, maintenance and internal cleaning of the tank. The time and economic costs of disassembly and maintenance are low.

[0043] The fixing plate is first installed on the base, and then the fixing plate is fitted onto the pin. After initial positioning, the crossbeam is fitted onto the connector from the side of the base. The pressure claw is movably connected to the bottom surface of the fixing plate, and the pressure claw repositions the fixing plate. After the crossbeam is in place, multiple fastening heads are tightened to achieve quick mounting of the mixing tank. The entire installation of the mixing tank can be achieved with fewer connecting mechanisms, and the disassembly and separation of the mixing tank from the base is also relatively quick and simple.

[0055] The tank body 3 is internally connected to a main shaft 8, and the geared motor 7 is linked to the main shaft 8 via a belt drive mechanism.

[0056] Several stirring rods 9 are fixedly connected to the outer surface of the main shaft 8, and a fan-shaped stirring head 10 is fixedly connected to the outer end of the stirring rods 9;

[0057] Several pins 11 are fixedly connected to the top of the base 1. The pins 11 are inserted into the fixing plate 2 from bottom to top. The surface of the fixing plate 2 is movably connected to the pressure claw 12. The bottom surface of the pressure claw 12 also presses against the top surface of the base 1. The end of the pressure claw 12 is fixedly connected to the crossbeam 13. The crossbeam 13 is stuck in the gap on the side of the base 1.

[0058] A connector 14 is fixedly connected to the side of the base 1. The connector 14 is inserted into the crossbeam 13. A fastening head 15 is threaded to the end of the connector 14 and is tightened on the surface of the crossbeam 13.

[0059] Example 1: The base 1 is I-shaped and welded to the tank 3. The transmission unit 6 includes a housing connected to the end of the tank 3, a pulley connected to the end of the main shaft 8, another pulley connected to the output end of the geared motor 7, and a belt movably connected to the surface of the pulleys. The main shaft 8 is riveted to the root of the stirring rod 9, and the stirring rod 9 is connected to the stirring head 10 by screws. The bottom surface of the pressure claw 12 has a rubber gasket, and the pressure claw 12 is welded to the crossbeam 13. The fastening head 15 is specifically a nut with a washer.

[0060] Example 2: Structural composition of the device: Foundation and support: The base 1 constitutes the basic support structure of the device, preferably designed as an I-beam structure to provide good stability and load-bearing capacity.

[0061] Several fixing plates 2 are disposed on the top of the base 1. The fixing plates 2 are not welded or permanently fixed to the base 1, but are detachably connected. The fixing plates 2 are fixedly connected to the tank 3 by welding or other secure methods, and together they bear the supporting and fixing functions of the tank.

[0062] A feed inlet 4 is fixedly installed at the top of the tank body 3 for material input. A discharge outlet 5 is fixedly installed at the bottom of the tank body 3 for material output after mixing. The discharge outlet 5 passes through a pre-drilled hole on the base 1 from top to bottom.

[0063] Power and transmission: The geared motor 7 is fixedly mounted on the top of the base 1. This is the power source of the device.

[0064] The transmission unit 6 is fixedly connected to the end of the tank body 3 (usually the drive end away from the geared motor 7). A belt drive mechanism is installed inside the transmission unit 6. This mechanism typically includes: a main pulley (A) fixed to the housing of the transmission unit 6 (usually the housing is fixed to the end of the tank body 3) for connecting to and driving the main shaft 8; a secondary pulley (B) connected to the output shaft of the geared motor 7; and a belt wrapped around the surfaces of pulleys A and B for transmitting power.

[0065] The main shaft 8 is movably connected inside the tank body 3, with its end (drive end) extending into the transmission section 6 and connecting to the internal pulley. The geared motor 7 drives the main shaft 8 to rotate via the pulley at its output end and the belt drive mechanism (located inside the transmission section 6).

[0066] Stirring components: Multiple stirring rods 9 are fixedly connected to the outer surface of the main shaft 8. Preferably, the root of the stirring rod 9 is connected to the main shaft 8 by riveting to ensure strength.

[0067] Each stirring rod 9 has a fan-shaped stirring head 10 fixedly connected to its outer end. Preferably, the stirring rod 9 and the fan-shaped stirring head 10 are connected by screws. The fan-shaped design helps to improve stirring efficiency and reduce resistance.

[0068] Quick assembly and disassembly mechanism (core advantage):

[0069] Several pins 11 are fixedly installed on the top of the base 1. During installation, the bottom of the fixing plate 2 is pre-drilled with corresponding holes so that it can be fitted onto the pins 11 from bottom to top, thereby achieving the initial positioning of the tank 3 assembly (including the fixing plate 2 and the tank 3) on the base 1.

[0070] Each fixed plate 2 has a pressure claw 12 movably connected to its surface (e.g., via a pivot connection). One working surface of the pressure claw 12 is located below the fixed plate 2.

[0071] The bottom surface (i.e. the working surface) of the pressure claw 12 has a pressing function, and the bottom surface eventually presses against the top surface of the base 1.

[0072] A crossbeam 13 is fixedly connected to the end of the pressure claw 12 (the end opposite to the end of the connecting fixing plate 2). The pressure claw 12 and the crossbeam 13 are preferably connected by welding. After installation, the crossbeam 13 is inserted into a specific gap or groove on the side of the base 1.

[0073] A connector 14 is fixedly connected to the side of the base 1. When the crossbeam 13 is inserted into the gap on the side of the base 1, the connector 14 passes through or is inserted into the preset hole on the crossbeam 13.

[0074] The end of connector 14 (typically extending beyond the crossbeam 13) is provided with external threads, forming a threaded connection with fastening head 15. Fastening head 15 is preferably a washered nut. By tightening fastening head 15, its washer is pressed tightly against the surface of crossbeam 13, thereby pulling crossbeam 13 and the connected pressure claw 12 downwards. After pressure claw 12 is pressed down, its bottom surface applies a downward force, firmly pressing the fixing plate 2 against the top surface of base 1, and simultaneously pressing the bottom surface of pressure claw 12 itself firmly onto base 1, thus achieving final locking and positioning of the tank body 3 assembly on base 1. A rubber gasket can be provided on the bottom surface of pressure claw 12 to increase friction and prevent slippage and wear.

[0075] The working principle of this utility model is as follows:

[0076] Mixing Process: The material enters the tank 3 through the feed inlet 4. When the reduction motor 7 is started, its output drives the pulley to rotate. This pulley, through a belt inside the transmission unit 6, drives the main pulley connected to the end of the main shaft 8 to rotate. The main pulley drives the main shaft 8 to rotate inside the tank 3. The stirring rod 9 and the fan-shaped stirring head 10, fixedly mounted on the main shaft 8, rotate together with the main shaft 8, thoroughly and efficiently mixing the material inside the tank 3. The mixed material is then discharged from the discharge port 5 at the bottom of the tank 3 under the action of gravity or the discharge mechanism.

[0077] Assembly Process (Quick Installation): First, hoist the tank body 3 assembly (including the main shaft 8, stirring rod 9, stirring head 10, transmission part 6 housing, etc.) with the welded fixing plate 2 onto the base 1. Initially position it using the pin 11, fitting the pin 11 into the hole at the bottom of the fixing plate 2, and initially place the tank body 3 assembly on the base 1. Next, operate the clamping claw 12 to insert the crossbeam 13 connected to it into the gap on the side of the base 1. Then, insert the connector 14 into the corresponding hole in the crossbeam 13. Finally, tighten the fastening head 15 (with washer nut) at the end of each connector 14. The tightening process causes the fastening head 15 to press down on the crossbeam 13, and the crossbeam 13, through the clamping claw 12, firmly presses and fixes the fixing plate 2 and tank body 3 assembly onto the base 1. The entire installation process only requires operation on a few fastening heads 15, making it very quick.

[0078] Disassembly Process (Quick Maintenance): When a comprehensive overhaul, cleaning, or maintenance of internal parts such as the main shaft 8 is required inside the tank 3, the operation is extremely simple: simply loosen and remove each fastener 15. After releasing the fasteners, the crossbeam 13, along with the pressure claw 12, can be easily moved away from the joint 14 and the base 1. At this point, the fixing plate 2 loses the downward pressure of the pressure claw 12, and the tank 3 assembly (along with the fixing plate 2) can be lifted upwards to remove it from the pin 11. After disassembly, the tank 3 can be lifted off the base 1 as a whole, providing ample operating space for comprehensive overhaul, maintenance, internal cleaning, or replacement of parts. After maintenance, it can be quickly reassembled and put back into use following the assembly process described above.

[0079] Compared with the prior art, the present invention has the following advantages:

[0080] This easy-to-install and maintain mixing device, under the premise of ensuring stable installation, has the tank body 3 fixed between the fixing plates 2. The tank body 3 and the base 1 are not directly welded, but assembled, which can be quickly assembled and disassembled. After the tank body 3 is separated from the base 1, the tank body 3 can be lifted away, which makes it relatively convenient to carry out a comprehensive inspection, maintenance and internal cleaning of the tank body 3. The time and economic costs of disassembly and maintenance are low.

[0081] The fixing plate 2 is first installed on the base 1. The fixing plate 2 is then fitted onto the pin 11. After initial positioning, the crossbeam 13 is fitted onto the connector 14 from the side of the base 1. The pressure claw 12 is movably connected to the bottom surface of the fixing plate 2. The pressure claw 12 repositions the fixing plate 2. After the crossbeam 13 is in place, multiple fastening heads 15 are tightened to achieve quick mounting of the mixing tank. The entire installation of the mixing tank can be achieved with fewer connecting mechanisms. The disassembly and separation of the mixing tank from the base 1 is also relatively quick and simple.
