Description

Technical Field

[0001] This utility model relates to the technical field of carbon black storage equipment, and in particular to a heat-insulating and humidifying box for carbon black testing. Background Technology

[0002] In the determination of the blackness of pigment carbon black, the pigment carbon black sample and standard reference carbon black No. 3 are mixed with refined linseed oil No. 44, and ground to obtain a uniform ink paste. This paste is then coated into a thin film of uniform thickness, and its blackness value is measured using a reflectometer. The blackness value of the sample is expressed as reflectance. To ensure the sample's condition during testing and avoid detection errors caused by changes in condition, the pigment carbon black or ink paste is usually stored in a heat-insulating and humidifying cabinet to prevent external interference. Application No. CN202321939967.7 discloses a heat-insulating cabinet with a humidifying structure, including a cabinet body and a support plate inserted into the cabinet body. The cabinet body includes a base, on which a water box is embedded. A heating element is provided at the bottom of the water box, and several exhaust holes are formed on the base to discharge hot air, thus creating a heat-insulating and humidifying space above the base. The aforementioned heat-insulating cabinet heats water, causing it to evaporate, thereby increasing both temperature and humidity. However, the aforementioned insulated cabinets can only achieve heating and humidification simultaneously through hot water evaporation, and cannot perform heating and humidification functions independently. Furthermore, cooling can only be achieved through natural cooling after heating is stopped; rapid temperature reduction is not possible, and it lacks a humidity reduction function, thus failing to effectively meet the requirements for sample preservation. Utility Model Content

[0003] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0004] A heat preservation and humidity control box for carbon black testing includes a box body. A heating box and a cooling box are located at the top of the box body, connected by a pipe.

[0027] refer to Figures 1-6 As shown, one embodiment of this utility model is as follows:

[0028] A heat-insulating and humidifying box for carbon black testing includes a box body 1. The box body 1 is formed by bolting together five double-layer hollow rectangular steel plates. The double-layer hollow rectangular steel plates can form an air layer between the steel plates, which can achieve a heat insulation effect and reduce the rate of heat loss. The five hollow rectangular steel plates respectively form the upper end face, lower end face, left end face, right end face and rear end face of the box body 1. The five end faces enclose a cavity for storing a paper bag containing the sample. The front end face of the box body 1 is hinged with a movable door 15 for opening and closing the box body 1 to facilitate the retrieval or storage of the sample. To facilitate the opening and closing of the movable door 15, a lock is provided at one end of the movable door. The lock is an existing technology, such as a padlock or a pin tumbler lock. Its specific structure and installation method can be selected according to actual needs and will not be described in detail. An observation window 16 is provided at the center of the movable door 15. The observation window 16 is made of heat-insulating transparent glass, such as existing double-layer hollow heat-insulating glass. Through the observation window 16, it is convenient to observe the storage status of the sample in the cavity at any time, and it can also reduce the rate of heat loss in the cavity.

[0029] The upper part of the housing 1 is equipped with a heating chamber 2 and a cooling chamber 3. Both the heating chamber 2 and the cooling chamber 3 store a medium liquid. The heating chamber 2 is equipped with a heating element 10 to raise the temperature of the medium liquid and achieves temperature rise and insulation of the chamber through heat exchange between the medium liquid and the air in the cavity of the housing 1. The cooling chamber 3 is connected to the heating chamber 2 by a pipe 4. The medium liquid in the cooling chamber 3 is transported to the heating chamber 2 to lower the temperature of the medium liquid in the heating chamber 2, thereby reducing the temperature in the cavity of the housing 1. The heating element 10 can be an electric heating rod, etc., and the medium liquid is preferably clean water.

[0030] The housing 1 is provided with a placement plate 5, which is used to place the sample. In this utility model, in order to increase the number of samples that can be placed, at least three placement plates 5 are evenly arranged from top to bottom. The placement plates 5 are detachably installed on the housing 1 by means of bolt connection.

[0031] The left and right side walls of the housing 1 and the interior of the placement plate 5 are all provided with circulation channels 6, and the circulation channels 6 on the left and right side walls of the housing 1 are connected to the circulation channels 6 on the placement plate 5. The circulation channels 6 are used for the flow and heat exchange of the medium liquid. In this utility model, the circulation channels 6 preferably use existing serpentine heat exchange tubes. The circulation channels 6 set on the housing 1 are located between the hollow rectangular steel plates of the double-layer structure. The circulation channels 6 set on the placement plate 5 can be fixed to the lower end face of the placement plate 5 by welding or pressing rings. The bottom of the heating box 2 is provided with an outlet 201 and an inlet 202. The outlet 201 is connected to the circulation channel 6 set on the left side wall of the housing 1. One end of the circulation channel 6 is connected to the outlet 201, and the other end is connected to one end of the circulation channel 6 set on the placement plate 5. The inlet 202 is connected to the circulation channel 6 set on the right side wall of the housing 1. One end of the circulation channel 6 is connected to the inlet 202, and the other end is connected to the other end of the circulation channel 6 set on the placement plate 5. The medium liquid in heating box 2 flows out from outlet 201 and flows in from inlet through circulation channel 6. Through circulation channel 6, it can fully exchange heat with the air in the cavity of box 1, thereby achieving heat preservation of box 1. When connecting circulation channel 6, it can be connected through existing connecting flanges, which can ensure both the flow and the sealing of circulation channel 6 after connection.

[0032] The heating box 2 is equipped with a circulation pump 7, which provides power for the flow of the medium liquid in the heating box 2, allowing the medium liquid to circulate back and forth between the circulation channel 6 and the heating box 2, so that it can continuously exchange heat with the cavity of the box body 1 to achieve the heat preservation function.

[0033] Specifically, the placement plate 5 is equipped with a nozzle 8, which is connected to the circulation channel 6 on the placement plate 5. The nozzle 8 can use an existing atomizing nozzle. When it is necessary to increase the humidity in the cavity of the box 1, the nozzle 8 can be turned on. The nozzle 8 sprays the clean water in the circulation channel 6 into the cavity in the form of water mist to increase the humidity in the cavity. Since the sprayed clean water is from the heating box 2, it will not reduce the temperature in the cavity of the box 1 after spraying, ensuring that the heat preservation temperature is not reduced while humidifying.

[0034] Specifically, a drying chamber 9 is provided at the upper end of the box body 1. The drying chamber 9 is connected to the box body 1 through a pipe 4, and a desiccant is placed in the drying chamber 9. The desiccant is silica gel, activated alumina, etc., which can adsorb water vapor in the cavity of the box body 1 through physical adsorption, thereby reducing the humidity in the cavity of the box body 1.

[0035] Valves 11 are provided on the pipes 4 used to connect the heating box 2 and the cooling box 3, as well as on the pipes 4 used to connect the box body 1 and the drying box 9. The valves 11 are preferably electric valves, and the connection of the pipes 4 can be controlled by controlling the opening and closing of the valves 11.

[0036] Both the heating box 2 and the cooling box 3 are equipped with a booster pump 12, which provides power for the mutual flow of the medium liquid in the heating box 2 and the cooling box 3.

[0037] Specifically, the interior of the enclosure 1 is equipped with a temperature sensor 13 and a humidity sensor 14. The temperature sensor 13 and humidity sensor 14 can monitor the temperature and humidity in the enclosure 1 in real time, which is convenient for real-time adjustment.

[0038] Specifically, the outer wall of the box 1 is provided with a heat insulation layer 17, which is made of polyurethane foam board, graphite modified polystyrene board, etc. The heat insulation layer 17 can reduce the rate of heat loss inside the box 1, improve the heat preservation effect, and allow the heating element 10 to maintain the temperature inside the box 1 with a lower power, thus saving costs.

[0039] Specifically, the upper surfaces of both the heating box 2 and the cooling box 3 can be opened for daily inspection and maintenance of components such as the heating element 10, the booster pump 12, and the circulating pump 7, as well as for daily replenishment or replacement of the medium liquid.

[0040] The working principle of this utility model:

[0041] First, open the movable door 15, place the sample on the placement plate 5, and then close the movable door 15. The heating element 10 starts working, heating the water in the heating chamber 2 to the specified temperature. Then, the circulation pump 7 starts working, allowing the water in the heating chamber 2 to circulate in the circulation channel 6. Through heat exchange between the hot water and the air, the temperature of the cavity of the chamber 1 is increased. When the temperature sensor 13 detects that the temperature has risen to the specified insulation temperature, the heating element 10 operates at a constant power to maintain the temperature. Then, the nozzle 8 is opened, spraying water mist into the chamber to increase the humidity in the chamber 1. When the humidity sensor 14 detects that the humidity has reached the specified humidity, the nozzle 8 is turned off, thus achieving the insulation and humidification function. When the temperature is higher than the specified insulation temperature, valve 11 in pipe 4 connecting heating chamber 2 and cooling chamber 3 can be opened, and booster pump 12 in cooling chamber 3 can be started. Booster pump 12 delivers low-temperature clean water from cooling chamber 3 to heating chamber 2 to lower the temperature. Once the temperature drops to the specified insulation temperature, booster pump 12 in cooling chamber 3 is closed, and booster pump 12 in heating chamber 2 is opened to re-deliver the clean water previously delivered to heating chamber 2 to cooling chamber 3. Then, booster pump 12 and valve 11 are closed, and the water in cooling chamber 3 cools naturally, ready for the next use. Conversely, when the temperature is lower than the specified insulation temperature, the power of heating element 10 can be increased. When the humidity is higher than the specified humidity, valve 11 in pipe 4 connecting chamber 1 and drying chamber 9 can be opened. The desiccant absorbs excess moisture, lowering the humidity. Once the humidity reaches the specified humidity, valve 11 is closed. When the humidity is lower than the specified humidity, nozzle 8 can be opened.
