Description

Technical Field

[0001] This utility model relates to the field of calorimeter technology, and in particular to an automatic oxygen bomb calorimeter cold water tank. Background Technology

[0002] An automatic oxygen bomb calorimeter is an instrument widely used in chemistry, food, and environmental fields. It is primarily used to determine the calorific value of substances. Its working principle involves burning a sample in a high-temperature, high-pressure oxygen environment, with the released heat being absorbed by a surrounding cold water tank. The cold water tank is a key component of the automatic oxygen bomb calorimeter, and its design and performance significantly impact the overall accuracy and stability of the instrument.

[0003] In existing technologies, fins are installed inside the cold water tank. In conjunction with other cooling mechanisms, they can quickly dissipate heat and cool the water inside the cold water tank that has absorbed heat. During long-term use, a large amount of impurities will accumulate on the surface of the fins and damage will occur. However, the traditional cold water tank and fins are fixed together by welding, which is inconvenient to disassemble. As a result, the maintenance or replacement of the fins will consume a lot of time and labor costs, which will seriously affect the efficiency of replacement and maintenance and reduce its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose an automatic oxygen bomb calorimeter cold water tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic oxygen bomb calorimeter cold water tank includes a base plate with a mounting groove on the top. A housing is movably inserted into the inner wall of the mounting groove. Two fixing blocks are fixedly installed on the outer wall of the housing. Two first bolts are movably inserted between each fixing block and the inner wall of the base plate, and the outer walls of the first bolts are threadedly connected to the fixing blocks and the inner wall of the base plate. A top cover is provided on the top of the housing, and two second bolts are movably inserted between the top cover and the inner wall of the housing, and the outer walls of the second bolts are threadedly connected to the top cover and the inner wall of the housing. A square groove is provided on the top of the base plate, and fins are movably inserted into the inner wall of the square groove.

[0007] Preferably, the outer wall of the fin has two limiting grooves, the outer wall of the base plate has two fixing grooves, the inner wall of each of the two fixing grooves is provided with a set of limiting springs, the inner wall of each of the two fixing grooves is movably embedded with a limiting plate, and one side of the outer wall of the limiting plate is fixedly connected to one side of the outer wall of the limiting spring.

[0008] Preferably, the outer walls of both limiting plates are movably inserted into the limiting groove.

[0009] Preferably, a heat insulation plate is movably inserted into the inner surface wall of the outer shell.

[0010] Preferably, an insulation plate is movably inserted into the inner surface wall of the outer shell, and a first sealing ring is provided on the outer surface wall of the top cover.

[0011] Preferably, the inner wall of the outer shell is provided with a second sealing ring, and a heat-conducting plate is fixedly installed on the inner wall of the square groove, with one side of the outer wall of the heat-conducting plate in contact with one side of the outer wall of the fin.

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

[0013] In use, when the fins inside the cold water tank need to be maintained or replaced, the cooling water inside is first drained, and the first and second bolts are removed under the operation of the staff, thereby completing the disassembly of the outer shell and top cover. Then, the limiting plate is pressed to remove it from the limiting groove, so that it no longer limits the fins, thereby completing the disassembly of the fins. This avoids the problem of inconvenient disassembly when the fins need to be replaced or maintained, greatly reduces the consumption of time and manpower, and improves the practicality of the device.

[0014] In use, when the cooling water is circulated and cooled through the cold water tank, the airtightness of the cold water tank can be improved by the action of the first and second sealing rings, avoiding the problem of cooling water leakage during use. At the same time, the heat insulation plate and the heat preservation plate can prevent external heat from being transferred to the inside of the cold water tank and thus prevent the cooling water from being cooled. This ensures the cooling efficiency of the fins and greatly reduces energy consumption. Attached Figure Description

[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 described in these embodiments 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: As Figures 1-4 As shown, this utility model provides a cold water tank for an automatic oxygen bomb calorimeter, including a base plate 1. A mounting groove 2 is formed on the top of the base plate 1. A housing 3 is movably inserted into the inner wall of the mounting groove 2. Two fixing blocks 4 are fixedly installed on the outer wall of the housing 3. Two first bolts 5 are movably inserted between each fixing block 4 and the inner wall of the base plate 1, and the outer wall of the first bolts 5 is threadedly connected to the fixing blocks 4 and the inner wall of the base plate 1. A top cover 8 is provided on the top of the housing 3, and a square opening is formed on the top of the base plate 1. The inner wall of the square groove 11 is movably fitted with fins 13. The outer wall of the fins 13 has two limiting grooves 17. The outer wall of the base plate 1 has two fixing grooves 14. The inner wall of each fixing groove 14 is provided with a set of limiting springs 15. The inner wall of each fixing groove 14 is movably fitted with a limiting plate 16. One side of the outer wall of the limiting plate 16 is fixedly connected to one side of the outer wall of the limiting spring 15. The outer walls of the two limiting plates 16 are movably inserted into the inside of the limiting groove 17.

[0024] The overall effect of Embodiment 1 is that when the fins 13 inside the cold water tank have accumulated a lot of impurities or become damaged during long-term use and need to be maintained or replaced, the cooling water inside the cold water tank is first discharged by the action of the external pump. Then, under the operation of the operator, the first bolt 5 is removed from the bottom plate 1 and the fixing block 4, so that it no longer fixes the bottom plate 1 and the outer shell 3. The outer shell 3 is then removed from the mounting groove 2. Under the operation of the operator, the limiting plate 16 is pressed to move outward in the fixing groove 14, and the limiting spring 15 is compressed, so that the limiting plate 16 is removed from the limiting groove 17. Thus, the limiting plate 16 no longer limits the fins 13, and the disassembly of the fins 13 is completed, making it easier for the operator to maintain or replace them, which greatly improves work efficiency.

[0025] Example 2: As Figures 2-4 As shown, a heat insulation plate 6 is movably inserted into the inner wall of the outer shell 3, a heat insulation plate 7 is movably inserted into the inner wall of the outer shell 3, a first sealing ring 9 is provided on the outer wall of the top cover 8, a second sealing ring 10 is provided on the inner wall of the outer shell 3, a heat conducting plate 12 is fixedly installed on the inner wall of the square groove 11, one side of the outer wall of the heat conducting plate 12 is in contact with one side of the outer wall of the fin 13, and two second bolts 18 are movably inserted between the top cover 8 and the inner wall of the outer shell 3, and the outer wall of the second bolts 18 is connected to the top cover 8 and the inner wall of the outer shell 3 by threads.

[0026] The overall effect of Embodiment 2 is that when a cold water tank is used to circulate cooling water to absorb the heat generated by the automatic oxygen bomb calorimeter, the cooling water circulates inside the cooling tank. Under the action of the fins 13, the heat-conducting plate 12, and the external cooling device, the cooling water can be cooled down. Furthermore, the sealing performance of the cold water tank can be improved by the action of the first sealing ring 9 and the second sealing ring 10, preventing leakage of cooling water during long-term use, thereby greatly improving the practicality of the cold water tank. At the same time, the insulation plate 6 and the insulation plate 7 can isolate the external heat of the cold water tank from the internal cooling water, thereby improving the heat dissipation and cooling efficiency of the fins 13 and reducing energy consumption. When the insulation plate 6 and the insulation plate 7 need to be replaced after long-term use, the second bolt 18 between the top cover 8 and the inner wall of the outer shell 3 is removed by the operator, thereby completing the disassembly of the top cover 8 and removing the insulation plate 6 and the insulation plate 7 from the inside of the outer shell 3 for replacement, further improving the work efficiency of the operator.

[0027] Working Principle: When a cold water tank is used to circulate cooling water to absorb the heat generated by the automatic oxygen bomb calorimeter, the cooling water circulates within the tank. Through the action of fins 13, heat-conducting plates 12, and external cooling devices, the cooling water is cooled. Furthermore, the first and second sealing rings 9 and 10 improve the tank's sealing, preventing leakage during prolonged use. Simultaneously, the insulation plates 6 and 7 prevent external heat transfer to the cooling water, thus improving the cooling efficiency of the fins 13 and reducing energy consumption. When the insulation plates 6 and 7 need replacement after prolonged use, the second bolt 18 between the top cover 8 and the inner wall of the outer shell 3 is removed by the operator, allowing the top cover 8 to be disassembled and the insulation plates 6 and 7 to be removed from the inside of the outer shell 3. After replacing the insulation plate 6 and insulation plate 7, when the fins 13 inside the cold water tank have accumulated a lot of impurities or are damaged during long-term use and need to be maintained or replaced, the cooling water inside the cold water tank is first discharged by the action of the external pump. Then, under the operation of the operator, the first bolt 5 is removed from the bottom plate 1 and the fixing block 4, so that it no longer fixes the bottom plate 1 and the outer shell 3. The outer shell 3 is then removed from the mounting groove 2. Under the operation of the operator, the limiting plate 16 is pressed to move outward in the fixing groove 14, and the limiting spring 15 is compressed, so that the limiting plate 16 is removed from the limiting groove 17. Thus, the limiting plate 16 no longer limits the fins 13, and the disassembly, maintenance and replacement of the fins 13 are completed. Through the above structure and method, the replaced and maintained fins 13, insulation plate 6 and insulation plate 7 can be reinstalled and put into use.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
