Description

A quick-install structure for a boiler sampling cooler Technical Field

[0001] This utility model relates to the field of sampling cooler technology, and in particular to a quick-assembly structure for a sampling cooler for boilers. Background Technology

[0002] Sampling coolers are used for cooling steam and water samples taken in boiler rooms or power plants. The water in boilers and thermal systems is mostly at a high temperature, which is not convenient for sampling or measurement. Therefore, the samples at the sampling point should be introduced into the sampling cooler for cooling.

[0003] However, existing sampling cooler designs are flawed, with cumbersome connections between components, typically requiring numerous bolts and other fasteners for fixation. When installed in the limited space around the boiler, this makes assembly difficult for operators, consuming significant time and manpower. Therefore, a quick-assembly structure for a boiler sampling cooler is proposed. Summary of the Invention

[0004] To overcome the technical shortcomings of existing sampling coolers, such as unreasonable structural design, cumbersome connection methods between various components, the need for a large number of bolts and other connectors for fixing, and the high time and manpower required, this utility model provides a quick-assembly structure for a boiler sampling cooler.

[0005] This utility model provides a quick-assembly structure for a boiler sampling cooler, including a topless cooling tank, a fixed cover, two sets of telescopic cylinders, a placement frame, and a cooler. The fixed cover is located on the top of the cooling tank. The two ends of the two sets of telescopic cylinders are respectively fixedly connected to the outer wall of the cooling tank and the bottom of the fixed cover, and are used to drive the fixed cover to move up and down along the axis of the cooling tank. The placement frame is located inside the cooling tank, and the top of the placement frame is detachably connected to the bottom of the fixed cover. The cooler is located inside the placement frame. The lower part of the cooling tank is connected to an inlet pipe and an outlet pipe.

[0006] The fixed cover, driven by two sets of telescopic cylinders, can move up and down along the axis of the cooling tank. The placement rack is fixed to the bottom of the fixed cover. When the fixed cover is raised or lowered, the placement rack, carrying the cooler, moves up and down together, allowing the cooler to be removed or placed in. The entire operation is very simple. The top of the placement rack is detachably connected to the fixed cover for easy removal of the cooler for replacement or maintenance. Boiler sampling water flows into the cooling tank through the inlet pipe. The sampling water passes through the cooler in the cooling tank. The cooler does not require electricity and uses a 50% ethylene glycol aqueous solution as refrigerant. The outer wall of the cooler is made of 316 stainless steel. The cooled sampling water then flows out through the outlet pipe. The rotating fan on top of the cooling tank is connected to an external power source and dissipates heat from the cooling tank. In actual use, valves are installed on both the inlet and outlet pipes.

[0007] Preferably, the placement rack has a barrel-shaped structure, with its axis parallel to the axis of the cooling tank and both located vertically. Multiple notches are evenly spaced along the side wall of the placement rack, and two clamping mechanisms are positioned opposite each other on the inner bottom of the rack. The cooler is fixedly installed between these two clamping mechanisms. The multiple notches allow direct contact between the cooler and the sampled water, enhancing the cooling effect. The two clamping mechanisms ensure stable installation of the cooler within the placement rack.

[0008] Preferably, the clamping mechanism includes a fixed plate, two compression springs, a push plate, and two insert rods. The fixed plate is fixedly connected to the inner wall of the placement frame. The outer wall of the push plate is connected to the inner wall of the fixed plate via the two compression springs. The two insert rods are fixedly connected to the inner wall of the push plate. The axes of the two insert rods and the two compression springs are parallel and perpendicular to the axis of the placement frame. The bottom of the cooler has a fixing slot corresponding to the insert rod. The insert rod and the fixing slot are fitted to fix the cooler between the clamping mechanisms of the placement frame. The fixed plate, compression springs, push plate, and insert rods are arranged horizontally, meaning the direction of movement of the clamping mechanism is horizontal. By pressing the insert rod and the push plate connected to the insert rod, the compression spring can be compressed, causing the insert rod to move outward, thereby increasing the distance between the two sets of clamping mechanisms and allowing the cooler to be removed from between the two sets of clamping mechanisms. Similarly, the cooler can also be installed between the two sets of clamping mechanisms.

[0009] Preferably, the top of the fixed cover has a heat dissipation vent, and a rotary fan for heat dissipation is mounted on the vent via a mounting bracket. The rotary fan can further remove heat from the cooling tank, thereby further cooling the sampled water.

[0010] Preferably, the telescopic cylinder includes a cylinder body and a piston rod connected together. The cylinder body is fixedly connected to the outer wall of the cooling tank, and the piston rod is movably connected to the upper side of the cylinder body. The top of the piston rod is fixedly connected to the bottom of the fixed cover. This arrangement is structurally sound.

[0011] Preferably, the top of the cooling tank has a circumferentially extending rim, on which a guide hole is formed for the piston rod to pass through. The piston rod passing through the guide hole ensures stability during operation.

[0012] Preferably, the bottom of the cooling tank is fixedly connected with at least three support legs. This arrangement is structurally sound.

[0013] Preferably, the top of the side wall of the shelf is connected to the fixed cover by bolts or threads. This arrangement is structurally sound. Besides bolted connections, other detachable connection structures can also be used.

[0014] The technical solution provided by this utility model has the following technical advantages compared with the prior art:

[0015] The quick-installation structure of this cooler features a reasonable design and simple, easy-to-operate connection between components. It requires no large number of bolts or other fasteners, making it very convenient for installation in limited spaces around the boiler. It makes full use of vertical space, is flexible in deployment and retraction, and saves time and manpower when replacing or repairing the cooler. During installation or repair, the telescopic cylinder extends upwards, moving the fixing plate upwards, which in turn moves the placement frame upwards, lifting the cooler from the cooling tank. The fixing cover and placement frame are then disassembled, and pressure is applied to the compression spring to remove the cooler from between the two opposing clamping mechanisms, facilitating disassembly and reducing the difficulty of installation and maintenance. During installation, the clamping mechanism's insert rod is inserted into the fixing slot at the bottom of the cooler for stable installation, ensuring the normal operation of the entire device. A heat dissipation vent and rotating fan are installed on the top of the fixing cover, further significantly improving the cooling tank's heat dissipation efficiency. Attached Figure Description

When the fixed cover 403 is raised or lowered, the placement rack 6, carrying the cooler 7, moves up and down together, allowing the cooler 7 to be removed or placed in. The entire operation is very simple. The top of the placement rack 6 is detachably connected to the fixed cover 403 to facilitate the removal of the cooler 7 for replacement or maintenance. Boiler sampling water flows into the cooling tank 1 through the inlet pipe 3. The sampling water passes through the cooler 7 in the cooling tank 1. The cooler 7 does not require electricity. The refrigerant used in the cooler 7 is a 50% ethylene glycol aqueous solution. The outer wall of the cooler 7 is made of 316 stainless steel.
