Description

Technical Field

[0001] This utility model relates to the field of ultrasonic descaling technology, specifically to an ultrasonic descaling device for heat exchangers. Background Technology

[0002] Ultrasonic descaling is a physical descaling method based on ultrasonic technology. It mainly uses high-frequency sound energy to act on the surface of fluids or metals to remove and inhibit scale. Ultrasonic waves generate high-frequency vibrations in liquids, forming microbubbles that burst instantly, generating high-pressure shock waves that destroy the scale structure. Ultrasonic descaling is used to clean heat exchangers and can effectively remove dirt remaining in narrow crevices. It uses mechanical shearing force to peel off the attached scale, and is especially suitable for high-hardness and strong-adhesion scale.

[0003] The utility model disclosed in CN204854465U is an ultrasonic descaling device for heat exchangers. The descaling device also includes a feedback measurement unit electrically connected to the ultrasonic generator. The feedback measurement unit includes a sensor disposed on the inner wall of the heat exchanger and a controller electrically connected to the sensor. The sensor is used to periodically detect the thickness of scale on the inner wall of the heat exchanger and transmit it to the controller. The controller can control the ultrasonic generator to generate an excitation signal of a corresponding frequency according to the detection value, thereby dynamically adjusting the frequency and amplitude of the ultrasonic waves.

[0004] However, the ultrasonic descaling devices for heat exchangers disclosed above still have the following problems in actual use: the descaling operation is achieved by adjusting the ultrasonic frequency inside the descaling device, but the volume, specifications, and arrangement of existing heat exchangers vary greatly, and such descaling devices cannot be uniformly adapted. As a result, the heat exchanger cannot be effectively positioned inside the descaling device, and resonance occurs when it comes into contact with the inner wall of the descaling device. This can easily cause the internal heat exchange components to loosen and be damaged, affecting the normal operation of the heat exchanger.

[0005] Therefore, we propose an ultrasonic descaling device for heat exchangers to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an ultrasonic descaling device for heat exchangers. It aims to solve the problem that existing descaling devices use adjustable ultrasonic frequencies to perform descaling operations. However, existing heat exchangers vary greatly in size, specifications, and arrangement, making it impossible to uniformly adapt such descaling devices. This results in the heat exchanger not being effectively positioned and placed inside the descaling device, causing resonance when in contact with the inner wall of the device. This can easily lead to loosening and damage of the internal heat exchange components, affecting the normal operation of the heat exchanger.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic descaling device for heat exchangers, comprising a support bracket and a cleaning tank fixedly installed inside the support bracket for ultrasonic descaling of the heat exchanger;

[0008] It also includes: a drive mechanism is provided above the support bracket, and the drive mechanism includes a drive platform, and a guide window is provided inside the drive platform;

[0009] The driver platform contains driver components.

[0010] The cleaning tank is equipped with a positioning mechanism, which includes a positioning filter plate, and the positioning filter plate is fixedly installed on the bottom surface inside the cleaning tank.

[0011] Preferably, the drive platform included in the drive mechanism is fixedly installed inside the support bracket, and the drive platform and the cleaning pool are coaxially aligned and correspond to each other. Furthermore, the length and width of the guide window inside the drive platform are greater than the length and width of the cleaning area inside the cleaning pool.

[0012] Preferably, the drive assembly includes a bidirectional threaded rod, which is rotatably mounted on the front and rear sides inside the drive platform via bearings, and the right ends of the bidirectional threaded rod are connected to each other via a pulley assembly, and the rear end of the bidirectional threaded rod is fixedly connected to the output shaft end of the servo motor.

[0013] Preferably, the drive assembly includes a pressure cylinder, which is fixedly installed on the left and right sides behind the drive platform, and a guide slide is fixedly installed in front of the drive platform to achieve clamping and positioning when performing ultrasonic descaling on the heat exchanger.

[0014] Preferably, the positioning mechanism includes a positioning bracket, the lower end of which is slidably mounted on the left and right sides inside the cleaning tank, and the upper end of which extends into the interior of the drive platform. By connecting with the drive components inside the drive platform, the positioning brackets on the left and right sides can move to achieve positioning during the descaling operation of the heat exchanger.

[0015] Preferably, the positioning mechanism includes positioning slide rods, which are fixedly installed on the front and rear sides of the positioning bracket near the top surface of the cleaning tank. The symmetrically arranged positioning slide rods are slidably installed inside the cleaning tank to improve the stability of the positioning bracket during movement and increase the clamping force when fitting the heat exchanger.

[0016] Preferably, the bottom end of the positioning bracket included in the positioning mechanism is slidably sleeved on the outside of the positioning filter plate, and the positioning filter plate is used to support the heat exchanger. Elastic contact rods are fixedly installed at equal intervals inside the positioning bracket. The elastic contact rods contact the outer wall of the heat exchanger to achieve close positioning and avoid affecting the ultrasonic descaling effect.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This heat exchanger uses an ultrasonic descaling device, which limits the positioning bracket through a drive platform above the cleaning tank, so that the drive assembly drives the positioning bracket to position and clamp the heat exchanger. The elastic clamping method keeps the heat exchanger confined inside the cleaning tank, improving the ultrasonic cleaning effect. The specific details are as follows:

[0018] 1. The heat exchanger is placed vertically in the center of the cleaning tank. Then, the servo motor on the right side of the drive platform drives the bidirectional threaded rod connected to the pulley assembly to rotate, which in turn drives the positioning brackets connected to the left and right sides to slide inward synchronously, so that the elastic contact rods set inside the positioning brackets can elastically position the heat exchanger.

[0019] Furthermore, the pressure cylinders installed on the left and right sides of the rear of the drive platform work, and the telescopic end of the cylinder drives the fixedly connected positioning bracket to slide inward synchronously. The guide slide rod at the front limits the positioning bracket, and cooperates with the positioning slide rod above the sliding cleaning tank to limit it, so that the positioning bracket can be adapted to clamp heat exchangers of different models and specifications.

[0020] 2. During the movement of the cleaning tank, the positioning brackets on the left and right sides are positioned by the positioning filter plates set at the bottom of the cleaning tank. After the dust and dirt inside the heat exchanger are cleaned and fallen off by ultrasonic waves, the positioning filter plates filter the dust and dirt, thereby improving the effect of ultrasonic cleaning.

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.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] Example 1: To address the problems existing in the use of existing ultrasonic descaling equipment, this example provides an ultrasonic descaling device for heat exchangers, comprising a support bracket 1 and a cleaning tank 2 fixedly installed inside the support bracket 1 for ultrasonic descaling of the heat exchanger; a driving mechanism is provided above the support bracket 1, and the driving mechanism includes a driving platform 3, and a guide window 4 is provided inside the driving platform 3; the driving platform 3 is fixedly installed inside the support bracket 1, and the driving platform 3 and the cleaning tank 2 are coaxially aligned vertically, and the length and width of the guide window 4 inside the driving platform 3 are greater than the length and width of the cleaning area inside the cleaning tank 2.

[0032] The drive platform 3 is equipped with a drive assembly; the drive assembly includes a bidirectional threaded rod 6, which is rotatably mounted on the front and rear sides inside the drive platform 3 via bearings, and the right ends of the bidirectional threaded rod 6 are connected to each other via a pulley assembly 7, and the rear end of the bidirectional threaded rod 6 is fixedly connected to the output shaft end of the servo motor 8.

[0033] like Figure 3 , Figure 5As shown, the drive assembly is installed on the drive platform 3 above the support bracket 1. During the descaling and cleaning of the heat exchanger, the heat exchanger is first placed vertically inside the cleaning tank 2. Then, the servo motor 8 installed on the outside right side of the drive platform 3 works to drive the bidirectional threaded rod 6 connected by the pulley assembly 7 to rotate. The positioning bracket 11, which is threadedly connected to the bidirectional threaded rod 6, is limited by the guide window 4 opened inside the drive platform 3 so that the rotating bidirectional threaded rod 6 can drive the threaded positioning bracket 11 to move towards the middle of the cleaning tank 2, thereby positioning the heat exchanger.

[0034] Example 2: To address the problems existing in the use of existing ultrasonic descaling equipment, this example employs the following technical solution: The drive assembly includes a pressure cylinder 9, which is fixedly installed on the left and right sides behind the drive platform 3. A guide slide rod 10 is fixedly installed on the front of the drive platform 3 to achieve clamping and positioning during ultrasonic descaling of the heat exchanger. The positioning mechanism includes a positioning bracket 11, the lower end of which is slidably installed on the left and right sides inside the cleaning tank 2. The upper end of the positioning bracket 11 extends into the interior of the drive platform 3 and is connected to the drive assembly inside the drive platform 3, allowing the positioning brackets 11 on the left and right sides to move and achieve positioning during the descaling operation of the heat exchanger.

[0035] like Figures 2-4 As shown, the heat exchanger is placed vertically inside the cleaning tank 2. Then, the pressure cylinders 9 installed on the left and right sides behind the drive platform 3 are pressurized by the oil pump, which drives the positioning brackets 11 fixedly connected to the inner end to move inward synchronously. At the same time, the front end of the positioning bracket 11 is positioned by the sliding guide rod 10, so that the positioning brackets 11 on the left and right sides can move synchronously to the outside of the heat exchanger to achieve positioning.

[0036] Example 3: To solve the problems existing in the use of existing ultrasonic descaling equipment, this example adopts the following technical solution: the cleaning tank 2 is provided with a positioning mechanism, and the positioning mechanism includes a positioning filter plate 5, which is fixedly installed on the bottom surface inside the cleaning tank 2; the positioning mechanism includes a positioning slide rod 12, which is fixedly installed on the front and rear sides of the positioning bracket 11 near the top surface of the cleaning tank 2, and the symmetrically arranged positioning slide rods 12 are slidably installed inside the cleaning tank 2 to improve the stability of the positioning bracket 11 during movement and increase the clamping force when fitting the heat exchanger.

[0037] The bottom end of the positioning bracket 11 included in the positioning mechanism is slidably sleeved on the outside of the positioning filter plate 5, and the positioning filter plate 5 is used to support the heat exchanger. Elastic contact rods 13 are fixedly installed at equal intervals inside the positioning bracket 11. The elastic contact rods 13 contact the outer wall of the heat exchanger to achieve close positioning and avoid affecting the ultrasonic descaling effect.

[0038] like Figures 5-7 As shown, the cleaning tank 2 is used to load the heat exchanger. Then, during the movement of the cleaning tank 2, the positioning brackets 11 on the left and right sides are positioned by the positioning filter plate 5 set at the bottom of the cleaning tank 2. After the dust and dirt inside the heat exchanger are cleaned and fallen off by ultrasonic waves, the dust and dirt are filtered by the positioning filter plate 5 and moved to the bottom of the positioning filter plate 5. Then, the positioning brackets 11 are elastically positioned by the elastic contact rods 13 set at equal intervals inside, which improves the descaling effect of ultrasonic vibration.
