Description

Technical Field

[0001] The invention relates to the technical field of agitators, and more particularly to a novel urea solution stirring and defoaming device. Background Art

[0002] During the production or use of urea solution, it is often necessary to stir it to ensure the uniformity of the solution and other related properties. However, foam is easily generated during the stirring process, which not only affects the stirring effect, but may also have a negative impact on subsequent process links.

[0003] There are some shortcomings in the existing stirring and defoaming devices. On the one hand, the stirring height of most stirring devices is fixed, and the height of the stirring motor cannot be flexibly adjusted according to factors such as the actual urea solution capacity and the size of the reactor, so that the stirring blade cannot be guaranteed to stir at the best position, affecting the defoaming and stirring efficiency. On the other hand, during the stirring process, there is a lack of real-time monitoring function for parameters such as solution temperature, and it is difficult for operators to accurately grasp the state changes of the solution, which is not conducive to timely adjustment of the stirring strategy. Moreover, the convenience of operation needs to be improved. For example, there is no integrated control interface for operations such as the extension and retraction of the stirring rod and the start-up of the stirring motor, which increases the difficulty and complexity of the operator's work. At the same time, the stability and durability of the device also need to be further optimized. For example, the design of the base may not be reasonable enough, and the problems of anti-slip and anti-corrosion are not taken into account. These problems have prompted the research and development of this new urea solution stirring and defoaming device. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a novel urea solution stirring and defoaming device, aiming to solve the problems in the prior art.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0008] A novel urea solution stirring and defoaming device comprises a base, wherein a vertical pole is arranged on the upper side of the base, a cross bar is arranged on one side of the vertical pole, a stirring motor is fixedly connected to the side end of the cross bar, a locking mechanism is arranged on the lower side of the vertical pole, and a lifting mechanism for adjusting the height of the stirring motor is arranged on the upper side of the base.

[0009] As a preferred solution of the present invention, the locking mechanism includes a rotating groove, which is drilled at the upper end of the base, and the inner wall of the rotating groove is rotatably connected to a rotating block, and the surface of the rotating block is drilled with multiple grooves, and the upper end of the base is drilled with a sliding groove, and the inner wall of the sliding groove is slidably connected to a locking block, the side end of the locking block is fixedly connected to a drag rod, and the drag rod slides through the side end of the base, and the adjacent ends of the sliding groove and the locking block are fixedly connected to a spring, and the spring is sleeved on the surface of the drag rod.

[0010] As a preferred solution of the present invention, the lifting mechanism includes a rack, the vertical rod is fixedly connected to the upper end of the rotating block, the rack is fixedly connected to the side end of the vertical rod, the surface of the vertical rod is slidably connected to the sliding frame, the cross bar is fixedly connected to the side end of the sliding frame, the surface of the cross bar is fixedly connected to the driving motor, the output shaft of the driving motor is fixedly connected to a gear, and the gear is meshingly connected to the rack.

[0011] As a preferred embodiment of the present invention, the output shaft of the stirring motor is fixedly connected to a telescopic stirring rod, the lower end of the telescopic stirring rod is fixedly connected to a stirring blade, and the lower end surface of the stirring blade is provided with a temperature probe.

[0012] As a preferred solution of the present invention, a placement plate is fixedly connected to the surface of the cross bar, and two lifting buttons, two telescopic buttons, a display screen and a stirring button are fixedly connected to the surface of the placement plate, the two lifting buttons are both connected to the drive motor signal, the two telescopic buttons are both connected to the telescopic stirring rod signal, the display screen is connected to the temperature probe signal, and the stirring button is connected to the stirring motor signal.

[0013] As a preferred solution of the present invention, the base has a size of 10 cm×20 cm, the rotating block is located in the middle of the base, and the material is stainless steel.

[0014] As a preferred solution of the present invention, a rubber pad is laid on the lower end of the base.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The lifting mechanism in the device can effectively solve the problem of fixed height of existing stirring devices. The gear is driven by the driving motor to rotate, and the meshing of the gear and the rack causes the sliding frame on the vertical rod to move up and down, thereby changing the height of the stirring motor. This design can flexibly adjust the position of the stirring blade according to the actual capacity of the urea solution and the size of the reactor. The operator can easily place the stirring blade at the optimal stirring height, making the stirring more sufficient and uniform, greatly improving the defoaming and stirring efficiency. Whether it is a large reactor in large-scale production or a small container in a small-scale experiment, this device can adapt to it, ensuring the consistency of the stirring effect and reducing the problems of foam residue and uneven stirring caused by improper stirring position.

[0017] The temperature probe installed on the lower end of the stirring blade is a highlight of this device. During the stirring process, the temperature probe can obtain the temperature information of the solution in real time and transmit it to the display screen. The operator can accurately grasp the state changes of the solution based on this. For example, when the temperature rises abnormally, it may indicate that an abnormal reaction has occurred inside the solution. The operator can adjust the stirring speed, suspend stirring, or take other corresponding measures in time. This helps to optimize the stirring strategy and avoid adverse effects on the quality of the urea solution due to excessively high or low temperatures. It can also prevent safety hazards caused by temperature problems, such as volatilization and explosion caused by overheating of the solution, thereby ensuring the safety and stability of the production process.

[0018] The control buttons on the surface of the plate placed on the crossbar realize the integrated control of the device. The two lifting buttons are connected to the drive motor signal, which is convenient for the operator to adjust the height of the stirring motor; the two telescopic buttons are connected to the telescopic stirring rod signal, which can easily control the extension and retraction of the stirring rod; the stirring button is connected to the stirring motor to start and stop stirring. This centralized control method greatly improves the convenience of operation. The operator does not need to find multiple control switches in different parts of the device, which reduces the operation steps and work difficulty. Moreover, the temperature information can be intuitively obtained through the display screen, so that the operator can fully understand the operating status of the device during the operation, further improving the operating efficiency and reducing the risk of misoperation due to complex operation.

[0019] The base size of the device is 10cm×20cm, and the rotating block is located in the middle of the base. Both are made of stainless steel. This design ensures the structural stability of the device. Stainless steel has good strength and corrosion resistance, and can withstand various forces during the stirring process, preventing the device from deformation, damage and other problems due to long-term use. At the same time, the rubber pad laid at the bottom of the base enhances the anti-slip performance of the device, so that it can be placed firmly on the operating platform during work, avoiding displacement of the device due to vibration or other external factors, and further ensuring the stability of the stirring process. This stable and durable design reduces the maintenance and replacement frequency of the device, reduces the cost of use, and increases the service life of the device, providing reliable hardware support for long-term stable urea solution stirring and defoaming work.

[0029] Example:

[0030] See also Figure 1-4 A novel urea solution stirring and defoaming device comprises a base 1, a vertical pole 9 is arranged on the upper side of the base 1, a cross bar 12 is arranged on one side of the vertical pole 9, a stirring motor 19 is fixedly connected to the side end of the cross bar 12, a locking mechanism is arranged on the lower side of the vertical pole 9, and a lifting mechanism for adjusting the height of the stirring motor 19 is arranged on the upper side of the base 1.

[0031] In this embodiment, the locking mechanism can lock the vertical rod 9 on the surface of the base 1 to prevent rotation, thereby increasing the working range of the stirring motor 19 and indirectly improving production efficiency. The lifting mechanism can raise and lower the stirring motor 19 so that the stirred materials and material barrels can be easily taken out and placed.

[0032] For details, please refer to Figure 1 and Figure 2 The locking mechanism includes a rotating groove 2, which is excavated at the upper end of the base 1. The inner wall of the rotating groove 2 is rotatably connected with a rotating block 3. A plurality of grooves 4 are excavated on the surface of the rotating block 3. A sliding groove 5 is excavated at the upper end of the base 1. A locking block 8 is slidably connected to the inner wall of the sliding groove 5. A drag rod 6 is fixedly connected to the side end of the locking block 8, and the drag rod 6 slides through the side end of the base 1. A spring 7 is fixedly connected to the adjacent ends of the sliding groove 5 and the locking block 8, and the spring 7 is sleeved on the surface of the drag rod 6.

[0033] In this embodiment, when it is necessary to deflect the direction of the vertical rod 9, the drag rod 6 is pulled outward to disengage the locking block 8 from the multiple slots 4, and then the vertical rod 9 is manually rotated to adjust the direction. After the adjustment is completed, the drag rod 6 is released, and the locking block 8 is reinserted into the corresponding slot 4 under the elastic recovery force of the spring 7. At this time, the rotating block 3 and the locking block 8 are locked, thereby preventing the rotating block 3 from shifting when vibrated, thereby expanding the working coverage area of ​​the stirring motor 19.

[0034] For details, please refer to Figure 1 and Figure 3 The lifting mechanism includes a rack 10, a vertical rod 9 fixedly connected to the upper end of the rotating block 3, the rack 10 fixedly connected to the side end of the vertical rod 9, a sliding frame 11 is slidably connected to the surface of the vertical rod 9, a cross bar 12 is fixedly connected to the side end of the sliding frame 11, a driving motor 13 is fixedly connected to the surface of the cross bar 12, and a gear 14 is fixedly connected to the output shaft of the driving motor 13, and the gear 14 is meshed with the rack 10.

[0035] In this embodiment, when the height of the cross bar 12 needs to be adjusted, the two lifting buttons 15 are pressed respectively as needed to start the drive motor 13, and the output shaft of the drive motor 13 drives the rotation of the gear 14. Since the gear 14 and the rack 10 are engaged with each other, the sliding frame 11 is driven to move up and down along the direction of the vertical rod 9, thereby completing the lifting function of the cross bar 12.

[0036] For details, please refer to Figure 1 The output shaft of the stirring motor 19 is fixedly connected with a telescopic stirring rod 20 , the lower end of the telescopic stirring rod 20 is fixedly connected with a stirring blade 21 , and the lower end surface of the stirring blade 21 is provided with a temperature probe.

[0037] In this embodiment, the telescopic stirring rod 20 is used to achieve fine adjustment in a small range, and the maximum telescopic length does not exceed 3CM. The temperature probe is set to monitor the solution temperature in real time.

[0038] Please refer to the figure and Figure 4 A placement plate 22 is fixedly connected to the surface of the cross bar 12, and two lifting buttons 15, two telescopic buttons 18, a display screen 16 and a stirring button 17 are fixedly connected to the surface of the placement plate 22. The two lifting buttons 15 are both connected to the drive motor 13 signal, the two telescopic buttons 18 are both connected to the telescopic stirring rod 20 signal, the display screen 16 is connected to the temperature probe signal, and the stirring button 17 is connected to the stirring motor 19 signal.

[0039] In this embodiment, two lifting buttons 15 control the operation of the driving motor 13 for lifting and lowering, two telescopic buttons 18 control the telescopic stirring rod 20 to extend and retract slightly, the display screen 16 is used to display the real-time temperature of the temperature probe for reading, and the stirring button 17 controls the stirring motor 19 to operate for stirring.

[0040] For details, please refer to Figure 1 The size of the base 1 is 10cm×20cm, and the rotating block 3 is located in the middle of the base 1, and the material is stainless steel.

[0041] In this embodiment, the rotating block 3 is located in the middle of the base 1 to maintain the stability of the center.

[0042] For details, please refer to Figure 1 , a rubber pad is laid on the lower end of the base 1.

[0043] In this embodiment, it is used to increase the friction between the base 1 and the ground.

[0044] Working principle: Before use, the device is placed on the operating platform through the base 1. The rubber pad at the lower end of the base 1 can ensure the stable placement of the device and prevent displacement due to external forces such as vibration during the stirring process. Since the base 1 and the rotating block 3 are made of stainless steel, the size is 10cm×20cm and the rotating block 3 is located in the middle of the base 1, a stable structural foundation is provided for the entire device, which can withstand the force generated by stirring and ensure the stability of long-term use. Then, the device is started. The operator can control the height of the stirring motor 19 through the lifting button 15 on the plate 22 on the surface of the crossbar 12. After pressing the lifting button 15, the signal is transmitted to the drive motor 13, the drive motor 13 is started, and its output shaft drives the gear 14 to rotate. Since the gear 14 is meshed with the rack 10 fixed on the side end of the vertical pole 9, and the vertical pole 9 is connected to the base 1 through the rotating block 3, the rotation of the gear 14 causes the sliding frame 11 connected to the crossbar 12 to slide up and down on the vertical pole 9, thereby realizing the adjustment of the height of the stirring motor 19. According to the capacity of the urea solution and the size of the reactor, the stirring motor 19 is adjusted to a suitable height so that the stirring blade 21 is in the best stirring position. Then, if the length of the stirring rod needs to be adjusted, the telescopic button 18 on the operating plate 22 can be operated. The telescopic button 18 sends a signal to the telescopic stirring rod 20 to achieve the telescopic stirring rod. After preparation, press the stirring button 17 to start the stirring motor 19, and the stirring motor 19 drives the telescopic stirring rod 20 and the stirring blade 21 to stir the urea solution. During the stirring process, the temperature probe on the lower end face of the stirring blade 21 monitors the solution temperature in real time and transmits the temperature information to the display screen 16. The operator observes the temperature data on the display screen 16 to grasp the change of the solution state. If the temperature is abnormal, such as too high or too low, the operator can adjust the stirring speed, suspend stirring or take other countermeasures in time to ensure the stirring effect and avoid safety hazards. The entire stirring and defoaming process is carried out in an orderly manner through such a process, which ensures the high efficiency, stability and safety of the stirring and defoaming work of the urea solution.
