Description

Technical Field

[0001] This utility model relates to the field of heat exchanger cleaning equipment, specifically an automatic granular agent replenishment device and heat exchanger cleaning equipment. Background Technology

[0002] Existing heat exchanger cleaning equipment using forward and reverse pulse cleaning without disassembly is limited by the operating environment, requiring a relatively small equipment size, resulting in a solvent tank volume of only 1 cubic meter. For plate heat exchangers with large cleaning areas, this leads to a sharp drop in cleaning agent concentration, significantly reducing the cleaning effect.

[0003] The original heat exchanger cleaning equipment required manual addition of cleaning agents when the cleaning solution concentration decreased. This was not only cumbersome and time-consuming, but the corrosive agents could also harm personnel. The original equipment could not automatically add cleaning agents. If the cleaning agent was granular, the amount needed to be determined based on the current solution concentration in the cleaning equipment, as granular agents have standard chemical-to-water ratio requirements and optimal solution concentrations. Manual addition resulted in inaccuracies and could not produce the correct dosage. Utility Model Content

[0004] The purpose of this invention is to provide an automatic granular agent replenishing device and heat exchanger cleaning equipment for heat exchanger cleaning. This device can automatically replenish an appropriate amount of granular agent to the heat exchanger cleaning equipment, so as to maintain the concentration of the cleaning agent solution at a high level.

[0005] The technical solution of this utility model:

[0006] An automatic granular agent replenishment device for heat exchanger cleaning equipment includes a support frame, a servo conveyor belt, a storage bin, a radial cylinder, a guide box, a tilting box, a load sensor, a sensor support, sliding guide columns, and a rotary cylinder. A conveyor belt support is fixed on the support frame, and a servo conveyor belt is mounted on the conveyor belt support. A storage bin is located on the upper side of the servo conveyor belt, and the lower end of the storage bin is fixedly connected to the support frame. A radial cylinder is fixedly mounted on the support frame on the side of the storage bin. The extension rod of the radial cylinder is connected to a baffle block, which abuts against the outlet of the storage bin. A tilting box is located below the outlet of the storage bin, and a load sensor is connected to the lower end of the tilting box. The load sensor is mounted on a sensor support frame. The rotary tables of two rotary cylinders are respectively connected to the two sides of the sensor support frame. Sliding guide columns are mounted on both sides of the tilting box on the sensor support frame. A guide box is fixed below the support frame, and the position of the guide box corresponds vertically to that of the tilting box.

[0007] The beneficial effects of this utility model are:

[0008] 1. The automatic granular cleaning agent replenishment device of this application realizes automatic replenishment of granular cleaning agent, and real-time monitoring and control of solution concentration in the solution tank, so as to keep the solution scale cleaning capacity of plate heat exchanger at a high level.

[0009] 2. The automatic granular agent replenishment device of this application has a compact structure and the bracket is equipped with connecting holes and connectors, which can be adapted to the existing heat exchanger pulse cleaning equipment and can achieve quick connection. In the case of cleaning small-area plate heat exchangers or when no replenishment of cleaning agent stock solution is required, the automatic replenishment system can be disassembled, making the operation flexible and convenient.

[0010] 3. The automatic granular agent replenishment device of this application enables unmanned automatic replenishment of granular agents. Some granular agents are corrosive and toxic; using this device can reduce the operational risks for workers and improve operational safety. Furthermore, manual replenishment of granular agents requires calculating the weight of the replenishing granules based on the agent concentration in the solution tank and manual operation from the top of the equipment, resulting in low efficiency and a low margin for error. This device can improve the overall operational efficiency and effectiveness of the equipment. Attached Figure Description

[0027] A heat exchanger cleaning device includes a pulse cleaning device 100 (a pulse cleaning device commonly used in the prior art), an automatic granule agent replenishing device 200, a pH sensor, and an electrical control box. The automatic granule agent replenishing device can be any of the devices described above. The feed box of the automatic granule agent replenishing device is inserted into the solution tank of the pulse cleaning device. The solution tank of the pulse cleaning device is equipped with a pH sensor, which transmits the detected pH data to the electrical control box. The power distribution box of the servo conveyor belt, the radial cylinder, and the rotary cylinder are electrically connected to the electrical control box.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] The current heat exchanger cleaning equipment on the market is not only difficult to operate when adding chemicals, but also very time-consuming. Therefore, it is imperative to design a cleaning device that automatically adds raw granular chemicals and has its own solution pH detection function.

[0030] As shown in the figure, the automatic granule replenishment equipment for the heat exchanger chemical cleaning equipment of this application includes a shaped and storage bin, a radial cylinder, a servo conveyor belt, a slip bar, a baffle block, a tilting box, a sliding guide column, a load sensor, a 180-degree rotating cylinder, a shaped guide box, a channel steel frame for the equipment, and various fixing parts for the mechanism.

[0031] Preparation: Install the automatic granule cleaning agent replenishing device on the upper channel steel frame of the existing pulse cleaning equipment. Connect the automatic granule cleaning agent replenishing device to the pre-drilled holes in the upper channel steel frame of the pulse cleaning equipment using bolts, ensuring that the irregularly shaped guide box mechanism of the automatic granule cleaning agent replenishing device is inserted into the filling port of the solution tank on the upper part of the pulse cleaning equipment. Add the granule cleaning agent into the irregularly shaped storage tank of the automatic granule cleaning agent replenishing device.

[0032] The equipment can set the amount of granular agent to be replenished each time based on the ratio of granular agent to water and the solubility of the solution in the pulse cleaning equipment. It can also be set to detect the concentration of the agent solution in the solution tank of the pulse cleaning equipment every ten minutes, and replenish the granular agent in real time based on the optimal agent concentration value calculated by the cleaning heat exchanger. Furthermore, it can automatically calculate the weight of granular agent to be replenished based on the solution concentration during the operation of the pulse equipment. The load sensor in the automatic granular agent replenishment equipment can detect and provide feedback on the weight of granular agent replenished each time, thereby ensuring the efficient operation of the pulse cleaning equipment.

[0033] When the concentration of cleaning agent in the tank of the pulse cleaning equipment decreases, the electrical control system detects that the pH sensor on the pulse cleaning equipment is below the set value, meaning the concentration of the cleaning solution is below the optimal efficiency concentration. This is defined as a decrease in the concentration of cleaning agent in the pulse cleaning equipment, and the automatic replenishment of granular cleaning agent begins. At this time, the automatic granular cleaning agent replenishment equipment starts working. The servo conveyor belt of the automatic replenishment system starts, and the radial cylinder retracts rapidly. The conveyor belt carries the granular cleaning agent from the irregularly shaped storage box into the tilting box. A slip strip made of polytetrafluoroethylene is installed between the irregularly shaped storage box and the conveyor belt, which protects the conveyor belt from scratches and ensures that the granular cleaning agent in the irregularly shaped storage box does not seep out through the gaps. The load sensor below the tilting box detects the weight of the introduced particles. When the weight reaches the amount of additional granular agent calculated by the equipment's electronic control system, the servo drive belt stops, the radial cylinder extends, and presses against the outlet of the irregularly shaped storage box. Simultaneously, it controls the 180-degree rotating cylinder to rotate downwards, guiding the granular agent from the tilting box into the irregularly shaped guide box. The granular agent then enters the solution tank of the pulse cleaning equipment. During the pulse cleaning equipment's operation cycle, the granular agent dissolves, thereby increasing the concentration of the cleaning solution in the pulse cleaning equipment's solution tank, achieving a high-efficiency cleaning solution concentration. After the granular agent replenishment is complete, the rotating cylinder returns to its original position. When the tilting box is facing down, due to the connection and cooperation between the tilting box and four sliding guide pillars, the tilting box structure will slide up and down, but will be limited by the sliding guide pillars. This ensures that when the tilting box is facing up, it does not affect the load sensor detection; when the tilting box is facing down, it will be limited. The equipment then returns to its initial state. The time interval for replenishing the granular agent is set according to the heat exchange area of ​​the heat exchanger to be cleaned and the type of granular agent, thereby ensuring that the pulse cleaning equipment continuously circulates a high concentration of cleaning solution, improving cleaning efficiency and reducing operation time.

[0034] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and implementations to the above embodiments without departing from the technical essence of the present invention, such designs should fall within the protection scope of the present invention.
