Description

Technical Field

[0001] This utility model relates to the technical field of single-effect concentrators, and in particular to a single-effect concentrator liquid replenishment and defoaming linkage device. Background Technology

[0002] Single-effect evaporators, widely used in the chemical, pharmaceutical, and food industries, function by vaporizing the solvent in a solution through heating, thereby increasing the solute concentration. During normal operation, due to the presence of surface-active substances in the material or changes in viscosity upon heating, a large amount of foam is continuously generated within the solution. This foam not only occupies effective evaporation space and reduces heat transfer efficiency but also causes a false rise in liquid level, leading to overflow risks and seriously affecting the stability and safety of the concentration process.

[0003] In existing technologies, defoaming devices mostly adopt a fixed design, which is structurally rigid and cannot automatically adjust to dynamic changes in the liquid level within the concentration tank. This fixed layout prevents the defoaming components from fully covering the liquid surface, especially when the liquid level fluctuates, easily creating defoaming dead zones that prevent timely foam breakage. Furthermore, operators need to frequently intervene manually to adjust the defoaming position, which not only increases labor intensity but also introduces the risk of human error, reducing the automation level and reliability of the process.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a single-effect concentrator liquid replenishment and defoaming linkage device is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a single-effect concentrator with a linkage device for replenishing liquid and defoaming.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a single-effect concentrator liquid replenishment and defoaming linkage device, comprising: a concentrator cylinder and a defoaming component disposed within the concentrator cylinder;

[0007] The defoaming component includes: a transmission rod, the two ends of which are rotatably connected to the top inner wall and bottom inner wall of the concentration cylinder, respectively; a through groove is provided inside the transmission rod; two symmetrical sliding grooves are provided on the inner circumference of the through groove; a servo motor is fixedly connected to the bottom of the concentration cylinder; one end of the output shaft of the servo motor passes through the concentration cylinder and is fixedly connected to the bottom of the transmission rod; a floating block is slidably connected inside the through groove; a connecting rod is fixedly connected to the bottom of the floating block; two stirring rods are fixedly connected to the outer circumference of the connecting rod; the two stirring rods are respectively located in the two sliding grooves and slidably connected; and a defoaming and breaking mesh is fixedly connected to the bottom of each of the two stirring rods.

[0008] A fixing plate is fixedly connected to the outer circumference of the concentration cylinder, and an output unit is provided on the upper surface of the fixing plate.

[0009] In a preferred embodiment of the present invention, the output unit includes a feed pump, which is fixedly connected to the upper surface of the fixed plate. The feed pump input end pipe is connected to a feed pipe, and the feed pump output end pipe is connected to a discharge pipe.

[0010] In a preferred embodiment of the present invention, the other end of the outlet tube passes through the fixing plate and communicates with the inside of the concentration cylinder, and the other end of the outlet tube is located at the bottom of the concentration cylinder.

[0011] In a preferred embodiment of this invention, a liquid level sensor is provided on the inner circumferential wall of the concentration cylinder.

[0012] In a preferred embodiment of this invention, the liquid level sensor is located in the middle of the concentration cylinder, and the liquid level sensor is electrically connected to the output unit and the servo motor.

[0013] In a preferred embodiment of this utility model, a through vent is provided at the bottom of the concentration cylinder.

[0014] In a preferred embodiment of this utility model, the bottom pipe of the concentration cylinder is connected to a discharge pipe.

[0015] In a preferred embodiment of this utility model, a number of support rods are fixedly connected to the bottom of the concentration cylinder.

[0016] In a preferred embodiment of this utility model, a protective shell is fixedly connected to the bottom of the concentration cylinder, and the servo motor is located inside the protective shell.

[0017] In a preferred embodiment of this utility model, the outer circumferential wall of the protective shell is provided with a plurality of through-holes for heat dissipation.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a single-effect concentrator liquid replenishment and defoaming linkage device. The transmission rod is provided with a through groove and a sliding groove. The floating block can slide up and down with the liquid level. The connecting rod drives the stirring rod and the defoaming and breaking net to always be submerged below the liquid surface. When the servo motor drives the transmission rod to rotate, the defoaming and breaking net directly breaks the foam with centrifugal force. This not only ensures that the defoaming action is synchronized with the liquid level fluctuation, but also significantly improves the defoaming efficiency and avoids the overflow problem caused by foam accumulation. Compared with the existing fixed defoaming devices, which often cannot adapt to changes in liquid level and require manual adjustment or have defoaming dead angles, the device body achieves fully automatic adjustment through a floating structure, further reducing the complexity of operation and enhancing the stability of the process.

[0020] (2) This utility model provides a single-effect concentrator liquid replenishment and defoaming linkage device. By placing a liquid level sensor in the middle of the concentrator cylinder, the liquid level is monitored in real time and electrically connected to the feed pump and servo motor. When the liquid level drops to the set position, the liquid replenishment and defoaming operations are automatically triggered. The outlet pipe is located at the bottom of the concentrator cylinder to avoid impacting the liquid surface when injecting materials, thereby reducing the generation of new foam. The servo motor starts synchronously to ensure timely defoaming. This integrated design directly ensures the continuity and uniformity of the concentration process. Compared with the response delay or control incoordination caused by the separation of liquid replenishment and defoaming links in the traditional system, the device body can respond quickly, further optimize energy consumption, and improve production safety and efficiency.

[0021] (3) This utility model provides a single-effect concentrator liquid replenishment and defoaming linkage device. Through details such as the low-position arrangement of the outlet pipe, the pressure balance of the vent hole, the heat dissipation hole of the protective shell, and the stable foundation of the support rod, the overall performance is improved. The outlet pipe reduces liquid replenishment disturbance, the vent hole prevents vacuum accumulation, the protective shell protects the servo motor from contamination, the heat dissipation hole promotes heat dissipation, and the support rod enhances the stability of the device.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figure 1 As shown, a single-effect concentrator liquid replenishment and defoaming linkage device includes: a concentrator cylinder 1, and a defoaming component disposed inside the concentrator cylinder 1;

[0027] like Figure 1As shown, the defoaming component includes: a transmission rod 12, the two ends of which are rotatably connected to the top inner wall and bottom inner wall of the concentration cylinder 1, respectively; a through groove 13 is provided in the transmission rod 12; two symmetrical sliding grooves 14 are provided on the inner circumference of the through groove 13; a servo motor 9 is fixedly connected to the bottom of the concentration cylinder 1; one end of the output shaft of the servo motor 9 passes through the concentration cylinder 1 and is fixedly connected to the bottom of the transmission rod 12; a floating block 15 is slidably connected in the through groove 13; a connecting rod 16 is fixedly connected to the bottom of the floating block 15; two stirring rods 17 are fixedly connected to the outer circumference of the connecting rod 16; the two stirring rods 17 are located in the two sliding grooves 14 and are slidably connected; and a defoaming and breaking mesh 18 is fixedly connected to the bottom of each of the two stirring rods 17.

[0028] A fixed plate 3 is fixedly connected to the outer circumference of the concentration cylinder 1. An output unit is provided on the upper surface of the fixed plate 3. The output unit includes a feed pump 4. The feed pump 4 is fixedly connected to the upper surface of the fixed plate 3. The feed pump 4 has an input pipe connected to a feed pipe 5 and an output pipe connected to an outlet pipe 6. The other end of the outlet pipe 6 passes through the fixed plate 3 and communicates with the inside of the concentration cylinder 1. The other end of the outlet pipe 6 is located at the bottom of the concentration cylinder 1.

[0029] A liquid level sensor 2 is provided on the inner circumference of the concentration cylinder 1. The liquid level sensor 2 is located in the middle of the concentration cylinder 1 and is electrically connected to the output unit and the servo motor 9.

[0030] It should be noted that the transmission rod 12 rotates under the drive of the servo motor 9, and the through groove 13 and the sliding groove 14 allow the floating block 15 to slide up and down with the change of liquid level, thereby driving the connecting rod 16 and the stirring rod 17 to adjust their positions; the floating characteristics of the floating block 15 ensure that the defoaming and breaking mesh 18 is always submerged below the liquid surface.

[0031] Specifically, when the servo motor 9 is running, the stirring rod 17 and the defoaming and breaking net 18 violently agitate the liquid under the action of centrifugal force, directly crushing the foam structure. This not only improves the defoaming efficiency, but also avoids the overflow problem caused by foam accumulation. This makes the defoaming process naturally linked with the liquid level change, and can maintain the best working state without external intervention.

[0032] Furthermore, the output unit on the fixed plate 3 is responsible for the liquid replenishment operation. The feed pump 4 draws in the raw material through the feed pipe 5 and delivers it to the bottom of the concentration cylinder 1 through the outlet pipe 6. The low-position design of the outlet pipe 6 avoids the liquid directly impacting the liquid surface, significantly reducing the generation of new foam during the liquid replenishment process, thus complementing the defoaming component.

[0033] Among them, the liquid level sensor 2 monitors the liquid level in the cylinder in real time. When the liquid level drops to the middle, it automatically triggers the feed pump 4 and servo motor 9 to start, so as to realize the simultaneous replenishment of liquid and defoaming. This electrical connection ensures the fully automated operation of the device, which saves manpower and ensures the continuity and stability of the concentration process.

[0034] The liquid level sensor 2 serves as the control center. Its layout in the middle of the concentration tank 1 can accurately reflect the real liquid level and avoid false triggering by top foam. Through linkage with the output unit and servo motor 9, the sensor can activate the liquid replenishment and defoaming functions in time when the liquid level is low and stop operating when the liquid level is high, thereby maintaining the liquid level within the ideal range.

[0035] like Figure 1 As shown, the bottom pipe of the concentration cylinder 1 is connected to the discharge pipe 19, the bottom of the concentration cylinder 1 is fixedly connected to several support rods 7, the bottom of the concentration cylinder 1 is fixedly connected to the protective shell 10, the servo motor 9 is located inside the protective shell 10, the outer circumferential wall of the protective shell 10 is provided with several through heat dissipation holes 11, and the bottom of the concentration cylinder 1 is provided with through vent holes 8.

[0036] It should be noted that the discharge pipe 19 at the bottom of the concentration cylinder 1 ensures the smooth discharge of concentrated material and supports continuous production process. The discharge pipe 19 is equipped with a valve to control the discharge flow rate. Several support rods 7 provide a stable foundation structure, enhance the overall stability of the device, and prevent vibration or tilting during operation. The protective shell 10 effectively protects the servo motor 9 from external contamination and physical damage. At the same time, the heat dissipation holes 11 on its outer circumference promote air circulation, achieve efficient heat dissipation, prevent the servo motor 9 from overheating, and extend its service life.

[0037] Vent 8 allows for gas exchange inside the cylinder, maintains pressure balance, and prevents vacuum or foam buildup, thereby improving safety and operational efficiency.

[0038] When this invention is in use, when the liquid level in the concentration tank 1 drops to the middle position, the liquid level sensor 2 will immediately detect the change in liquid level and trigger the control unit to start the relevant components; the operator only needs to ensure that the external power supply is connected and the material pipeline is unobstructed, and the device can enter an autonomous operation state without manual intervention. The entire operation process relies on real-time feedback of the liquid level to ensure that the concentration process continues continuously;

[0039] In the defoaming process, after the servo motor 9 starts, it drives the transmission rod 12 to rotate at high speed. The floating block 15 in the through groove 13 floats up and down with the liquid level. The connecting rod 16 drives the stirring rod 17 to move in the sliding groove 14. The defoaming and breaking net 18 at the bottom of the stirring rod 17 is always submerged below the liquid surface. The centrifugal force generated by the rotation directly acts on the foam layer to achieve continuous breaking operation.

[0040] The replenishment operation is performed by the feed pump 4. When the liquid level is too low, the pump body automatically draws in the material from the feed pipe 5 and delivers the liquid to the bottom of the concentration cylinder 1 through the outlet pipe 6 to avoid direct impact on the liquid surface and reduce foam generation. At the same time, the concentrated material can be discharged through the discharge pipe 19 at the bottom. The support rod 7 and the protective shell 10 ensure the stability of the device during operation. The heat dissipation hole 11 promotes the cooling of the servo motor 9 and ensures long-term use.

[0041] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
