A boiler cleaning and dosing device

Abstract

This utility model provides a boiler cleaning chemical dosing device, relating to the field of boiler cleaning technology. It includes an operation panel with a chemical dosing rack fixedly mounted on its top. Two columns are fixedly mounted on the top of the dosing rack. Each of the two columns has two limiting grooves on its inner surface. L-shaped limiting blocks are movably embedded in the inner surface of each of the four limiting grooves. A strip plate is fixedly installed between the tops of the four L-shaped limiting blocks. In this utility model, starting the drive motor causes it to drive a drive rod and multiple stirring blades to mix the chemical and water. Then, activating two electric push rods causes them to move the strip plate stably up and down, thereby moving the drive motor, drive rod, and multiple stirring blades up and down.

This improves the dissolution rate, uniform distribution, and contact of the chemical with substances inside the boiler, thus enhancing the cleaning and protection effect on the boiler.

Description

Technical Field

[0001] This utility model relates to the field of boiler cleaning technology, and in particular to a boiler cleaning chemical dosing device. Background Technology

[0002] A boiler is a device used to heat liquids and convert them into steam or hot water. It consists of components such as a combustion chamber, heat exchange pipes, and a control system. The function of a boiler is to heat water to a certain temperature and produce steam for industrial production, heating, or power generation. Because harmful substances such as oxides, alkaline substances, and scale are generated inside the boiler, they can cause corrosion and blockage of the boiler's metal parts or pipes. By adding chemicals, these problems can be prevented, extending the boiler's service life.

[0003] However, in existing technologies, the chemicals are usually added directly into the boiler, which cannot guarantee that the chemicals can be evenly distributed inside the boiler, and thus cannot guarantee the cleaning effect on the boiler. Therefore, a chemical dosing device for boiler cleaning is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing equipment cannot guarantee the cleaning effect of the boiler because it cannot ensure that the chemical can be evenly distributed in the boiler. Therefore, a boiler cleaning chemical dosing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a boiler cleaning chemical dosing device, comprising an operation panel, a chemical dosing rack fixedly installed on the top of the operation panel, two columns fixedly installed on the top of the chemical dosing rack, two limiting grooves opened on the inner surface of each of the two columns, L-shaped limiting blocks movably embedded in the inner surface of each of the four limiting grooves, a strip plate fixedly installed between the tops of the four L-shaped limiting blocks, an electric push rod fixedly installed on one side of the inner wall of each of the two columns, and the output ends of the two electric push rods fixedly connected to the bottom of the strip plate, a drive motor fixedly installed on the top of the strip plate, a drive rod fixedly installed on the bottom of the drive motor, and the outer surface of the drive rod movably inserted into the inside of the strip plate.

[0006] Preferably, a plurality of stirring blades are fixedly installed on the outer wall of the drive rod, and a dosing box is fixedly installed on the top of the dosing rack.

[0007] Preferably, a controller is fixedly installed on one side of the outer wall of the dosing tank, and the outer wall of the controller is electrically connected to the outer wall of the drive motor.

[0008] Preferably, the bottom of the dosing tank is provided with a dosing hole, and a dosing pipe is fixedly installed on the inner wall of the dosing hole.

[0009] Preferably, a solenoid valve is fixedly installed on the outer wall of the dispensing tube, and one side of the outer wall of the controller is electrically connected to the outer wall of the solenoid valve.

[0010] Preferably, a protective cover is fixedly installed on the top of the strip plate, and a through hole is opened on the top of the dosing rack, with the outer wall of the dispensing tube connected to the inside of the through hole.

[0011] Preferably, the boiler body is fixedly installed on the top of the control panel.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the agent and water are first placed in the dosing tank. Then, the drive motor is started by the controller, which drives the drive rod and multiple stirring blades to mix the agent and water. Then, two electric push rods are started. Under the action of four limit grooves and four L-shaped limit blocks, they drive the strip plate to move up and down stably, thereby driving the drive motor, drive rod and multiple stirring blades to move up and down, thereby changing the running trajectory of the stirring, so that the agent and water in the dosing tank can be fully mixed. This can improve the dissolution rate, uniform distribution and contact of the agent with the substances inside the boiler, thereby improving the cleaning and protection effect of the boiler.

[0014] 2. In this utility model, after the agent and water are fully mixed, the solenoid valve is opened by the controller, so that the agent-water mixture in the dosing tank enters the boiler through the dosing hole and the outlet pipe. Under the action of the solenoid valve and the controller, an appropriate amount of agent can be added in a certain proportion to ensure that the concentration and dosage of the agent meet the requirements and will not have an adverse effect on the boiler, thereby further improving the effect of the dosing device in boiler cleaning.

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, such as Figures 1-4 As shown, this utility model provides a boiler cleaning chemical dosing device, including an operation panel 1, a chemical dosing rack 2 fixedly installed on the top of the operation panel 1, two columns 3 fixedly installed on the top of the chemical dosing rack 2, two limiting grooves 4 opened on the inner surface of each of the two columns 3, L-shaped limiting blocks 5 movably embedded in the inner surface of each of the four limiting grooves 4, a strip plate 6 fixedly installed between the tops of the four L-shaped limiting blocks 5, an electric push rod 7 fixedly installed on one side of the inner wall of each of the two columns 3, and the output ends of the two electric push rods 7 are fixedly connected to the bottom of the strip plate 6, a drive motor 8 fixedly installed on the top of the strip plate 6, a drive rod 9 fixedly installed on the bottom of the drive motor 8, and the outer surface of the drive rod 9 movably inserted into the inside of the strip plate 6.

[0024] The overall effect of Embodiment 1 is as follows: the controller 12 starts the drive motor 8, which drives the drive rod 9 and multiple stirring blades 10 to rotate, so that the agent and water in the dosing tank 11 are fully mixed. Then, the controller 12 starts two electric push rods 7. Since four limiting grooves 4 are opened on the inner surface of the two columns 3, and the four L-shaped limiting blocks 5 installed on both sides of the strip plate 6 are movably embedded in the four limiting grooves 4, the two electric push rods 7 can drive the strip plate 6 to move up and down stably, thereby driving the drive motor 8, drive rod 9 and multiple stirring blades 10 to move up and down, thereby changing the running trajectory of multiple stirring blades 10. Then, the drug-water mixture is added to the boiler instead of adding the drug directly, so that the agent and water in the dosing tank 11 are fully mixed. This can improve the dissolution rate, uniform distribution and contact of the agent with the substances inside the boiler, thereby improving the cleaning and protection effect of the boiler.

[0025] Example 2, as Figures 2-4 As shown, multiple stirring blades 10 are fixedly installed on the outer wall of the drive rod 9, a dosing box 11 is fixedly installed on the top of the dosing rack 2, a controller 12 is fixedly installed on one side of the outer wall of the dosing box 11, and one side of the outer wall of the controller 12 is electrically connected to the outer wall of the drive motor 8, a dosing hole 13 is opened at the bottom of the dosing box 11, a dispensing pipe 14 is fixedly installed on the inner wall of the dosing hole 13, a solenoid valve 15 is fixedly installed on the outer wall of the dispensing pipe 14, and one side of the outer wall of the controller 12 is electrically connected to the outer wall of the solenoid valve 15, a protective cover 16 is fixedly installed on the top of the strip plate 6, a through hole 17 is opened on the top of the dosing rack 2, and the outer wall of the dispensing pipe 14 is connected to the inside of the through hole 17, and a boiler body 18 is fixedly installed on the top of the control panel 1.

[0026] The overall effect of Embodiment 2 is that after the agent and water are fully mixed, the solenoid valve 15 is opened by the controller 12, so that the mixed agent enters the boiler through the dosing hole 13 and the outlet pipe 14. Through the action of the solenoid valve 15 and the controller 12, an appropriate amount of agent can be added in a certain proportion to ensure that the concentration and dosage of the agent meet the requirements and will not have an adverse effect on the boiler. Then, by quantitatively adding the agent-water mixture, the cleaning effect can be maximized and the risk of waste and environmental pollution can be reduced, thereby further improving the effect of the dosing device in boiler cleaning.

[0027] Working principle: First, when boiler cleaning is required and chemicals need to be added, the chemicals and water are added to the dosing tank 11. Then, the drive motor 8 is started by the controller 12, which drives the drive rod 9 and multiple stirring blades 10 to mix the chemicals and water. Next, the two electric push rods 7 are started. Since the four L-shaped limit blocks 5 installed on both sides of the strip plate 6 are movably embedded in the four limit grooves 4, the two electric push rods 7 can drive the strip plate 6 to move stably up and down, thereby changing the running trajectory of the multiple stirring blades 10 in the dosing tank 11 and making the chemicals and water fully mixed. After the mixture is uniform, the controller 12 is then opened. The solenoid valve 15 allows the uniformly mixed chemical solution to enter the boiler through the outlet pipe 14 for thorough cleaning. The controller 12 and solenoid valve 15 provide automated control and quantitative dispensing, ensuring the chemical solution enters the boiler at a specific ratio, guaranteeing the concentration and dosage of the chemicals meet requirements and do not adversely affect the boiler. In summary, when boiler cleaning is required, the chemical dosing device ensures uniform mixing of the chemicals, improving the dissolution rate, even distribution, and full contact with the boiler's internal substances, thereby enhancing the cleaning and protection effects and improving the overall effectiveness of the boiler cleaning chemical dosing device.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
