Description

Technical Field

[0001] This invention belongs to the field of coal temperature control technology, and specifically relates to a temperature control device. Background Technology

[0002] In the process of determining the calorific value of coal, a cooling coil and heating tubes are typically installed inside the water cylinder of the calorimeter to maintain a constant temperature environment. Existing cooling coils are mostly spiral or serpentine wound, lacking effective spacing and lateral restraint structures during installation. During operation, the impact of water flow easily causes the coils to collide with each other, resulting in pipe wall wear, uneven heat exchange, and even interference with the heating tubes. Simultaneously, gaps exist between the cooling coil and the inner wall of the water cylinder, making the coil prone to lateral swaying and affecting temperature control stability. Furthermore, the inner diameter of the water cylinder varies among different calorimeter specifications, and existing fixing methods make it difficult to flexibly adjust the distance between the coil and the cylinder wall, resulting in poor installation adaptability. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art. To this end, embodiments of the present invention provide a temperature control device that can reduce the mutual shaking and collision of the coils of the cooling coil during use, thereby improving the stability of temperature control.

[0004] The temperature control device of this invention includes a cooling coil, multiple isolation plates, multiple bonding plates, and multiple adjusting components.

[0005] The cooling coil is a multi-layered tubular structure, installed inside the water cylinder of the calorimeter, and used to circulate a temperature-regulating medium. Multiple isolation plates are spaced apart circumferentially on the periphery of the cooling coil, with at least a portion of the isolation plates connected to the cooling coil in layers. Multiple bonding plates are spaced apart circumferentially on the side of the isolation plates away from the cooling coil. An adjusting element is connected between the isolation plates and the bonding plates, used to adjust the distance between the bonding plates and the isolation plates so that the bonding plates fit snugly against the inner wall of the water cylinder.

[0006] The temperature control device of this invention uses multiple isolation plates spaced apart along the periphery of the cooling coil to separate and support the various concentric pipes of the cooling coil, preventing water flow impact from causing collisions between the pipes. Simultaneously, by adjusting the distance between the bonding plate and the isolation plates using an adjusting component, the bonding plate can adapt to water cylinders of different inner diameters and fit tightly against their inner walls. This reliably fixes the cooling coil in the center of the water cylinder or a designated position, preventing lateral swaying of the cooling coil or interference with the heating pipe, significantly improving the installation stability and heat exchange uniformity of the cooling coil within the water cylinder.

[0007] In some embodiments, the adjusting element includes a screw and an inner threaded tube. One end of the screw is fixedly connected to the isolation plate, the inner threaded tube is threaded to the outside of the screw, and the end of the inner threaded tube is rotatably connected to the bonding plate.

[0008] In some embodiments, the adjusting member further includes a plurality of telescopic sleeves, which are spaced apart between the isolation plate and the bonding plate along the stacking direction of the cooling coil, and the telescopic sleeves are used to guide the movement of the bonding plate.

[0009] In some embodiments, the isolation plate is provided with a plurality of retaining rings, which are sleeved on the outside of the cooling coil to connect the isolation plate with at least a portion of the cooling coil.

[0010] In some embodiments, the retaining ring is a semi-circular elastic plate, and the inner wall of the retaining ring is provided with an anti-slip layer.

[0011] In some embodiments, the side of the bonding plate near the inner wall of the water tank is an arc surface, and a rubber layer is provided on the arc surface.

[0012] In some embodiments, the temperature control device further includes a chassis disposed at the bottom of the cooling coil for placement on the inner bottom wall of the water cylinder.

[0013] In some embodiments, the bottom of the chassis is provided with an anti-slip pad, and the bottom of the anti-slip pad has an adsorption groove.

[0014] In some embodiments, the temperature control device further includes a constant temperature control box, which is connected to the cooling coil via a circulation pipe, and the constant temperature control box is used to control the temperature of the temperature regulating medium.

[0015] In some embodiments, the temperature control device further includes a heating tube and a heating control module. The heating control module is disposed on the constant temperature control box, and the heating tube is connected to the heating control module. The heating tube is used to heat the water in the water tank. Attached Figure Description

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1-4 As shown, the temperature control device of this embodiment includes a cooling coil 1, multiple isolation plates 2, multiple bonding plates 3, and multiple adjusting members 4. The cooling coil 1 is a multi-layered tubular structure, disposed in the water cylinder of the calorimeter, and is used to circulate the temperature-regulating medium. The multiple isolation plates 2 are spaced apart along the circumference of the cooling coil 1, and at least a portion of the isolation plates 2 are connected to the cooling coil 1. The multiple bonding plates 3 are spaced apart along the circumference of the isolation plates 2 on the side away from the cooling coil 1. The adjusting members 4 are connected between the isolation plates 2 and the bonding plates 3, and are used to adjust the distance between the bonding plates 3 and the isolation plates 2 so that the bonding plates 3 are in contact with the inner wall of the water cylinder.

[0023] The temperature control device of this invention uses multiple isolation plates 2 spaced apart along the periphery of the cooling coil 1 to separate and support the various concentric pipes of the cooling coil 1, preventing water flow impact from causing collisions between the pipes. Simultaneously, the spacing between the bonding plate 3 and the isolation plates 2 is adjusted by the adjusting component 4, allowing the bonding plate 3 to adapt to water cylinders of different inner diameters and fit tightly against their inner walls. This reliably fixes the cooling coil 1 in the center of the water cylinder or a designated position, preventing lateral swaying of the cooling coil 1 or interference with the heating pipe, significantly improving the installation stability and heat exchange uniformity of the cooling coil 1 within the water cylinder.

[0024] Specifically, the cooling coil 1 consists of a multi-layered, stacked tubular structure, such as a spiral coil or a serpentine stacked coil. The cooling coil 1 can be made of copper or stainless steel, offering good thermal conductivity and corrosion resistance. The upper and lower ends of the cooling coil 1 are connected to a thermostatic control box 7 via circulation pipes 8. The thermostatic control box 7 provides a circulating temperature-regulating medium (such as constant-temperature water or coolant). As the temperature-regulating medium flows through the cooling coil 1, it exchanges heat with the water in the water tank, absorbing excess heat.

[0025] In some embodiments, the adjusting member 4 includes a screw 401 and an inner threaded tube 402. One end of the screw 401 is fixedly connected to the isolation plate 2, the inner threaded tube 402 is threadedly connected to the outside of the screw 401, and the end of the inner threaded tube 402 is rotatably connected to the bonding plate 3.

[0026] In this embodiment, the adjusting component 4 uses a threaded adjustment method to achieve stepless adjustment of the distance between the bonding plate 3 and the isolation plate 2. When it is necessary to adapt to water tanks of different diameters, rotating the inner threaded tube 402 will drive the bonding plate 3 to move axially along the screw 401. Since the inner threaded tube 402 is rotatably connected to the bonding plate 3, the bonding plate 3 will not rotate with the inner threaded tube 402 during the adjustment process, keeping the orientation of the bonding plate 3 unchanged, which facilitates stable contact with the inner wall of the arc-shaped water tank. This structure has high adjustment accuracy, is easy to operate, and can self-lock to prevent loosening due to vibration after adjustment.

[0027] Specifically, the screw 401 is welded or threaded to the outer center of the isolation plate 2. The internal threaded tube 402 is an internally threaded fitting, and its outer wall may be provided with knurled or hexagonal operating parts for manual rotation. The end of the internal threaded tube 402 is rotatably connected to the inner side of the bonding plate 3 through a thrust bearing or a smooth ring.

[0028] Furthermore, the adjusting element 4 also includes multiple telescopic sleeves 403. The multiple telescopic sleeves 403 are spaced apart between the isolation plate 2 and the bonding plate 3 along the stacking direction (i.e., the vertical direction) of the cooling coil 1, and the telescopic sleeves 403 are used to guide the movement of the bonding plate 3.

[0029] In this embodiment, the telescopic sleeve 403 serves as a guide and limiter during the movement of the bonding plate 3, preventing the bonding plate 3 from tilting or shifting during adjustment and ensuring that the bonding plate 3 always moves parallel to the isolation plate 2. This ensures that the outer surface of the bonding plate 3 can uniformly adhere to the inner wall of the water cylinder. Simultaneously, the telescopic sleeve 403 also bears part of the supporting load, reducing the stress on the screw 401 and the inner threaded tube 402, and improving structural stability.

[0030] Specifically, the telescopic sleeve 403 includes a sliding rod and a sleeve. One end of the sliding rod is fixedly connected to the isolation plate 2, and one end of the sleeve is fixedly connected to the bonding plate 3. The sleeve is fitted onto the outside of the sliding rod and slidably connected to it. Multiple telescopic sleeves 403 can be symmetrically arranged on the upper and lower sides of the screw 401.

[0031] In some embodiments, the isolation plate 2 is provided with a plurality of retaining rings 5. The retaining rings 5 ​​are sleeved on the outside of the cooling coil 1 so that the isolation plate 2 is connected to at least a portion of the coils of the cooling coil 1.

[0032] In this embodiment, the isolation plate 2 and the cooling coil 1 are detachably connected via retaining rings 5. During installation, the retaining rings 5 ​​are sequentially engaged on the outer sides of each coil of pipe in the cooling coil 1 to fix the isolation plate 2 to the periphery of the cooling coil 1 without the need for tools, making assembly and disassembly convenient. The retaining rings 5 ​​are spaced apart along the stacking direction of the cooling coil 1, which can isolate the coils of pipe in the cooling coil 1 vertically and prevent collisions between pipes.

[0033] Specifically, such as Figure 2 As shown, the retaining ring 5 is a semi-circular elastic plate with an anti-slip layer on its inner wall. The semi-circular elastic plate is elastic, allowing it to slightly open to accommodate cooling coils 1 of different diameters, and then tightly engages with the outside of the pipe after its elasticity returns. The anti-slip layer can be made of rubber or silicone to increase friction with the pipe surface and prevent the cooling coil 1 from sliding or rotating within the retaining ring 5. The retaining ring 5 and the isolation plate 2 can be integrally molded to improve overall strength and durability; alternatively, they can be detachably connected to adjust the number and position of the retaining rings 5 ​​according to the number of coils in the cooling coil 1.

[0034] In some embodiments, the side of the bonding plate 3 closest to the inner wall of the water cylinder is an arc surface, and a rubber layer is provided on the arc surface. The arc surface matches the curvature of the inner wall of the cylindrical water cylinder, increasing the contact area and improving the bonding stability. The rubber layer has elastic and anti-slip properties, which can buffer vibration and increase friction, further preventing the device from lateral shaking.

[0035] In some embodiments, the temperature control device further includes a chassis 6. The chassis 6 is disposed at the bottom of the cooling coil 1 for placement on the inner bottom wall of the water tank.

[0036] In this embodiment, the chassis 6 provides bottom support for the cooling coil 1, keeping the cooling coil 1 vertical and preventing it from sinking or tilting due to gravity. The chassis 6 can be designed as a circular plate or a cross-shaped bracket, and its size is adapted to the inner diameter of the water tank.

[0037] Furthermore, the bottom of the chassis 6 is equipped with an anti-slip pad, and the bottom of the anti-slip pad has an adsorption groove. The anti-slip pad can be made of rubber or silicone. When the chassis 6 presses against the bottom of the water tank, the adsorption groove expels the internal air, forming a negative pressure adsorption effect, which enhances the fixing force between the chassis 6 and the bottom of the tank and prevents the chassis 6 from shifting due to water flow impact.

[0038] In some embodiments, the temperature control device further includes a constant temperature control box 7. The constant temperature control box 7 is connected to the cooling coil 1 via a circulation pipe 8, and is used to control the temperature of the temperature regulating medium.

[0039] The thermostatic control box 7 can be equipped with a circulating pump, a refrigeration unit, and a temperature controller. During operation, the circulating pump drives the temperature regulating medium to circulate between the thermostatic control box 7 and the cooling coil 1. The temperature controller adjusts the start / stop or power of the refrigeration unit according to the temperature control requirements of the calorimeter, so that the temperature regulating medium entering the cooling coil 1 is maintained at the set temperature, thereby accurately controlling the water temperature in the water tank.

[0040] Furthermore, the temperature control device also includes a heating tube 9 and a heating control module 10. The heating control module 10 is installed on the constant temperature control box 7, and the heating tube 9 is connected to the heating control module 10. The heating tube 9 is used to heat the water in the water tank.

[0041] In this embodiment, the heating tube 9 serves as an auxiliary heating element, working in conjunction with the cooling coil 1 to achieve bidirectional regulation of the water temperature inside the water tank. When the water temperature inside the water tank is lower than the set value, the heating control module 10 activates the heating tube 9 to heat the water; when the water temperature is higher than the set value, the constant temperature control box 7 drives the cooling medium to flow through the cooling coil 1 for cooling. Through the coordination of cooling and heating, the water temperature inside the water tank is stabilized within the required range, meeting the stringent requirements of a constant temperature environment for coal calorific value determination.

[0042] Specifically, the heating element 9 can be a stainless steel electric heating element, arranged vertically or bent inside the water tank, located inside or outside the cooling coil 1. The heating control module 10 includes a temperature controller and a solid-state relay, which can receive signals from the temperature sensor inside the water tank to achieve automatic constant temperature control.

[0043] The usage process of the temperature control device according to an embodiment of the present invention will be described below in conjunction with its specific working method.

[0044] First, place the base plate 6 on the inner bottom wall of the calorimeter water cylinder. The anti-slip pad and adsorption groove on the bottom of the base plate 6 adhere to the bottom of the cylinder, thus securing the bottom. Then, place the cooling coil 1 vertically on the base plate 6. Adjust the adjusting components 4 according to the inner diameter of the water cylinder: rotate the inner screw tube 402. Driven by the thread of the screw 401, the inner screw tube 402 moves the bonding plate 3 away from or towards the isolation plate 2. At the same time, the telescopic sleeve 403 provides guidance for the bonding plate 3, keeping it moving parallel. When the outer arc surface and rubber layer of the bonding plate 3 are tightly attached to the inner wall of the water cylinder, stop rotating. The adjusting components 4 retain their position by the self-locking of the threads. At this time, multiple bonding plates 3 are supported from multiple points around the inner wall of the water cylinder, fixing the cooling coil 1 at the center of the water cylinder.

[0045] Subsequently, the retaining rings 5 ​​on each isolation plate 2 are sequentially engaged with the outer sides of each coil of pipe in the cooling coil 1. The retaining rings 5 ​​use their own elasticity to hold the pipe tightly, and the anti-slip layer increases friction, ensuring that the isolation plates 2 are firmly installed around the perimeter of the cooling coil 1. The isolation plates 2 separate the upper and lower adjacent coils of the cooling coil 1, preventing water flow impact from causing collisions between pipes.

[0046] After the device is installed, the calorimeter is started to determine the calorific value of the coal. The constant temperature control box 7 drives the temperature regulating medium to circulate through the cooling coil 1, while the heating control module 10 automatically controls the start and stop of the heating tube 9 based on the water temperature in the water tank. When the water temperature in the water tank is too high, the temperature regulating medium flowing in the cooling coil 1 absorbs heat from the water and carries it back to the constant temperature control box 7 through the circulation pipe 8 for heat dissipation; when the water temperature is too low, the heating tube 9 is energized to heat up and raise the water temperature. Through the combined effect of cooling and heating, the water temperature in the water tank is maintained within the set constant temperature range.

[0047] During the operation of the device, the isolation plate 2 maintains the spacing between the layers of the cooling coil 1, and the bonding plate 3 and the adjusting piece 4 together maintain the lateral fixation of the cooling coil 1 to prevent shaking and collision caused by water flow impact or external vibration, so as to ensure uniform and stable heat exchange and improve the accuracy of coal calorific value measurement results.
