Description

Technical Field

[0001] The invention relates to the technical field of steam pipeline sampling, and in particular to a sampling cooler. Background Art

[0002] Steam pipes are pipe systems used to transport steam. They are widely used in industry, commerce, and homes for heating, power transmission, power generation, and various other processes. They are usually made of metals such as steel or stainless steel and are resistant to high temperatures and high pressures. Steam dryness refers to the percentage of liquid water in steam. Wet steam with a high moisture content may cause corrosion to pipes and equipment, especially under high temperature and high pressure conditions. The moisture in wet steam may form rust on the surface of equipment, causing damage to the equipment and reducing its life. Maintaining proper steam dryness can reduce these problems. Steam pipe dryness testing helps ensure the reliable operation of the steam system, protect equipment from damage, improve production efficiency, and meet the requirements of regulations and standards. Taking samples from steam pipes to test steam dryness is a key step in ensuring steam quality. Sampling requires selecting representative locations to ensure that the device is safe and leak-free.

[0004] However, this patent cannot collect and process the water remaining in the condenser.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

[0006] The object of the present invention is to provide a sampling cooler which can effectively solve the above technical problems.

[0010] Furthermore, a support is installed on the sample storage box; The support member includes: a support sleeve, a reset member fixedly installed on the support sleeve, a clamping block fixedly installed on the reset member, a buffer member fixedly installed on the support sleeve, a connecting rod fixedly connected to the buffer member, and the connecting rod is fixedly connected to the sample storage box.

[0011] Furthermore, a drug storage chamber is provided on the contact surface between the sampling box and the detection box, a liquid inlet is provided on the drug storage chamber, and a drug taking rod is provided for taking out the detection liquid in the drug storage chamber and delivering it into the detection box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a sampling cooler.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0020] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 14 As shown, a sampling cooler of the present invention includes: a boiler, a water supply unit, a sampling box 1, a cooling unit 2, and a sampling detection unit 3. The sampling box 1 cools the boiler feed water through the cooling unit 2 and transports the water to the sampling detection unit 3. The sampling detection unit 3 detects the dryness of the boiler feed water and stores it for easy retrieval.

[0022] The cooling unit 2 includes a cooling pipe 22 and a cooling fan 21 for cooling the cooling pipe 22 .

[0023] The water inlet end of the cooling pipe 22 receives boiler feed water, and the cooling fan 21 blows air to the cooling pipe 22 to dissipate heat, thereby accelerating the cooling speed, so that the boiler feed water can be directly cooled to a suitable temperature after the staff takes samples, which is convenient for subsequent testing.

[0024] The cooling pipe 22 includes: a water inlet pipe 222, a threaded cooling pipe 221 connected to the water inlet pipe 222, and an inverter 2221 installed at the connection between the water inlet pipe 222 and the threaded cooling pipe 221. The boiler feed water enters the threaded cooling pipe 221 through the water inlet pipe 222. In this embodiment, two groups of threaded cooling pipes 221 are provided, and the two groups of threaded cooling pipes 221 are connected to each other. The flow path of the boiler feed water is extended by the two groups of threaded cooling pipes 221, which can increase the cooling effect of the boiler feed water. When the ambient temperature is not high, the boiler feed water can be cooled to a suitable temperature without activating the cooling fan 21. When the ambient temperature is high, the heat is exchanged through the threaded cooling pipe 221. When it is difficult for the boiler feed water to reach the ideal temperature, the cooling fan 21 is activated to reasonably optimize the cooling solution and avoid waste of resources.

[0025] The sampling and detection unit 3 includes: a sampling box 31, a detection box 32 fixedly installed on the sampling box 31, and a sample storage box 33 fixedly installed on the sampling box 1; the sampling box 31 can perform preliminary storage on the boiler feed water and transport it to the sampling bottle 317, the detection box 32 is used to perform dryness detection on the boiler feed water, and the sample storage box 33 is used to store part of the boiler feed water for manual collection or sampling.

[0026] A baffle 311 is slidably connected in the sampling box 31, a spring 314 is fixedly installed on the baffle 311, and a sampling bottle 317 is fixedly installed on the sampling box 31; the baffle 311 divides the sampling box 31 into a sampling area and a cleaning area, and the sampling bottle 317 is detachably installed on the sampling area; the threaded cooling pipe 221 is connected to the sampling area, the threaded cooling pipe 221 is connected to a three-way valve, the three-way valve is connected to a shunt pipe 2211, and the shunt pipe 2211 is connected to the cleaning area; During sampling, boiler feed water enters the sampling area and drives the baffle 311 to move, causing the spring 2 314 to deform, and a pressure valve is provided at the connection between the sampling bottle 317 and the water pipe. When the pressure in the sampling box 31 matches, the boiler feed water in the sampling box 31 will flow into the sampling bottle 317, and the sampling of the boiler feed water is stopped at this time; then the spring 2 314 pushes the baffle 311 to reset, and the baffle 311 pushes the boiler feed water in the sampling area into the sampling bottle 317 for storage, which is convenient for quantitative use. At the same time, the baffle 311 is reset under the deformation of the spring 2 314, and the three-way valve is controlled to be connected with the shunt pipe 2211. When the baffle 311 is reset, the pressure in the cleaning area is reduced, and the residual boiler feed water in the threaded cooling pipe 221 is sucked into the cleaning area through the shunt pipe 2211, so as to avoid the boiler feed water remaining in the threaded cooling pipe 221 and affecting the accuracy of subsequent sampling of the boiler feed water.

[0027] It can be seen from the above that when the boiler feed water enters the sampling box 31, on the one hand, it can drive the baffle 311 to move, thereby increasing the space of the sampling area and transferring more boiler feed water; on the other hand, when the baffle 311 is reset, it can clean up the boiler feed water remaining in the threaded cooling tube 221, thereby optimizing the sampling effect and avoiding sampling residues that affect the subsequent sampling accuracy.

[0028] It should be supplemented with respect to the above that a medicine storage chamber 315 is provided on the contact surface between the sampling box 31 and the detection box 32, the medicine storage chamber 315 is provided with a liquid inlet 316, and a medicine taking rod 3131 for taking out the detection liquid in the medicine storage chamber 315 and sending it into the detection box 32, the medicine taking rod 3131 is fixedly connected with a gear 313, the gear 313 is meshed with a rack 312, the rack 312 is fixedly connected to the baffle 311, a medicine taking port 31311 is provided on the medicine taking rod 3131, the medicine taking rod 3131 is connected with a limiting sleeve 3132, a stirring blade 3133 is fixedly connected to the upper part of the medicine taking rod 3131, and a guide groove 31321 is provided on the limiting sleeve 3132.

[0029] That is to say, when the baffle 311 is reset, the remaining boiler feed water in the threaded cooling tube 221 is extracted and enters the detection box 32 through the liquid inlet 316; when the baffle 311 moves, it drives the rack 312 to move, and through the engagement of the rack 312 and the gear 313, the gear 313 drives the medicine taking rod 3131 and the stirring blade 3133 to rotate. The stirring blade 3133 is located inside the detection box 32, and can detect the boiler feed water reduction. A guide block that cooperates with the guide groove 31321 is installed on the surface of the medicine taking rod 3131. When the medicine taking rod 3131 rotates, the guide block slides inside the guide groove 31321. Since the limit sleeve 3132 is rotatably connected to the sampling box 31, the medicine taking rod 3131 moves up and down under the action of the guide groove 31321; since the thickness of the gear 313 is greater than the width of the rack 312, when the gear 313 and the medicine taking rod 3131 move synchronously, the gear 313 and the rack 312 are always engaged. When the medicine taking rod 3131 moves downward, the medicine taking port 31311 enters the interior of the medicine storage chamber 315, and the detection liquid for detecting the boiler feed water in the medicine storage chamber 315 flows out through the medicine taking port 31311 into the interior of the detection box 32, and detects the boiler feed water inside the detection box 32, with good use effect.

[0030] It can be seen from the above description that, on the one hand, when the baffle 311 moves, the engagement of the gear 313 and the rack 312 can drive the stirring blade 3133 to stir the boiler feed water; on the other hand, during the stirring process, the detection liquid in the medicine storage chamber 315 can be continuously input into the detection box 32 in small quantities and multiple times. At the same time, the reaction speed of the detection liquid and the boiler feed water is accelerated by stirring, thereby improving the detection efficiency of the boiler feed water.

[0031] like Fig.10 As shown, the guide groove 31321 is composed of two sets of thread grooves which are coaxially opened on the inner wall of the limiting sleeve 3132, have the same pitch, opposite thread direction, and are connected to each other.

[0032] In order to improve the accuracy of adding the detection liquid when feeding water to the boiler, the device also includes: a medicine feeder 3151 is fixedly installed on the sampling box 31, a medicine feeder port 31511 is provided on the medicine feeder 3151, a shell 1 31512 is installed on the medicine feeder 3151, the shell 1 31512 is slidably connected with the shell 2 31513, a pressure inlet 31514 is installed on the shell 2 31513, a spring 31515 is installed on the shell 2 31513, and a medicine feed pipe 31516 is provided on the shell 1 31512; two groups of pressure inlets 31514 are provided, and the two groups of pressure inlets 31514 are respectively connected to the medicine storage chamber 315 and the detection box 32.

[0033] It should be noted here that a pressure valve is provided at the pressure inlet 31514. When it is necessary to add detection liquid to the inside of the detection box 32, the medicine feeder 3151 is pressed. At this time, the shell 1 31512 moves toward the direction of the shell 2 31513. The pressure in the chamber formed by the shell 1 31512 and the shell 2 31513 increases, causing the pressure valve to open, and the detection liquid in the medicine feeder 3151 is discharged through the pressure inlet 31514, and the detection liquid is added to the inside of the detection box 32. Since the contact surfaces between the medicine inlet 31511 and the shell 1 31512 and the shell 2 31513 are inclined surfaces, when the shell 1 31512 moves, the medicine inlet 31511 moves upward under the guidance of the inclined surface. At this time, the medicine inlet 31511 is not connected to the medicine inlet pipe 31516, and a closed chamber is formed between the shell 1 31512 and the shell 2 31513, which can prevent the detection liquid from flowing out and causing pollution. When the shell 1 31512 approaches the shell 2 31513, the spring 31515 is compressed. When the pressure on the medicine inlet 3151 stops, the spring 31515 is reset, which can drive the shell 1 31512 to reset, so that it is convenient for the next use. The detection medicine added to the detection box 32 is tested again through the medicine inlet 3151, which can more accurately reflect the specific value of the dryness in the boiler feed water, and the test result is more accurate.

[0034] It should be supplemented with respect to the above that, since the drug feeder 3151 is connected to the drug storage chamber 315 through the pressure inlet 31514, and since the same liquid is injected and the liquid is not flowing, the liquid level in the container is always maintained at the same horizontal plane, so that the detection liquid inside the drug feeder 3151 and the detection liquid in the drug storage chamber 315 are highly consistent. This means that when the detection liquid inside the drug feeder is insufficient, the detection liquid inside the drug storage chamber 315 will flow into the drug feeder, thereby ensuring that there is sufficient detection liquid inside the drug feeder. In addition, the detection liquid inside the drug feeder 3151 can be added synchronously through the drug inlet 31511 to supplement the detection liquid inside the drug storage chamber 315, resulting in good use effect.

[0035] A partition 22211 installed on the inverter 2221, a rotating shaft 22212 fixedly installed on the partition 22211, a spring 22214 fixedly connected to the rotating shaft 22212, a sleeve 22213 fixedly connected to the spring 22214, a converter plate 22215 fixedly connected to the sleeve 22213, a sealing plate 22221 slidably connected to the inverter 2221, and a sampling tube 2222 fixedly connected to the sealing plate 22221; the sampling tube 2222 is communicated with the sample storage box 33; the sleeve 22213 is coaxially connected to the rotating shaft 22212, and the sleeve 22213 is rotatably connected to the partition 22211.

[0036] The converter 2221 is divided into a cooling water inlet chamber and a sampling water inlet chamber by a partition 22211. The boiler feed water enters the sampling water inlet chamber through the water inlet pipe 222, and then enters the sample storage box 33 through the sampling tube 2222 for storage. When the internal storage volume of the sample storage box 33 is sufficient, the sample storage box 33 moves downward, driving the sampling tube 2222 to move, and squeezes the converter plate 22215 through the sealing plate 22221. The converter plate 22215 rotates through the sleeve 22213, so that the cooling water inlet chamber and the sampling water inlet chamber are separated. The boiler feed water enters the cooling water inlet chamber and is transported to the sampling box 31 through the threaded cooling pipe 221. The boiler feed water flow path can be replaced through the inverter 2221, and the boiler feed water can be stored separately. The appropriate boiler feed water sample can be selected according to the actual detection needs. It should be noted that when the above-mentioned baffle rotates, the spring 1 22214 is deformed under force. When the sealing plate 22221 stops squeezing the baffle, the spring 1 22214 drives the baffle to reset, which is convenient for the next use.

[0037] The specific structure of the sample storage box 33 moving downward is: a support member 331 is installed on the sample storage box 33; the support member 331 includes: a support sleeve 3311, a reset member 3312 fixedly installed on the support sleeve 3311, a block 3313 fixedly installed on the reset member 3312, a buffer member 3314 fixedly installed on the support sleeve 3311, a connecting rod 3315 fixedly connected to the buffer member 3314, and the connecting rod 3315 is fixedly connected to the sample storage box 33.

[0038] The sample storage box 33 moves inside the support sleeve 3311 through the connecting rod 3315, and at the same time abuts against the block 3313. The block 3313 is provided with an inclined surface. When the connecting rod 3315 is pressed down, the block 3313 is guided by the inclined surface to squeeze the reset member 3312. At the same time, as the pressure of the sample storage box 33 gradually increases, the block 3313 enters the inside of the support sleeve 3311, and at the same time, the connecting rod 3315 squeezes the buffer member 3314 to prevent the connecting rod 3315 from falling directly and causing an impact. The reset member 3312 and the buffer member 3314 can both be springs.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
