[0002] The enzyme substrate method is a common detection method for the detection of total coliform bacteria, thermotolerant coliform bacteria and Escherichia coli in drinking water, urban sewage, etc. When using the enzyme substrate method, the sample needs to be cultured at an appropriate temperature for a specified time. According to the relevant provisions of the national standards GB / T5750.12-2006 "Microbiological Indicators of Standard Test Methods for Drinking Water", HJ1001-2018 "Determination of Total Coliform Bacteria, Fecal Coliform Bacteria and Escherichia coli in Water Quality", the enzyme substrate method culture temperature uniformity requirements need to meet 37±1℃, 44.5±0.5℃.

[0003] The temperature probe of the existing enzyme substrate method incubator is often placed inside the storage incubator, and the heating plate is controlled according to the temperature collected by the internal probe, which has a certain lag and cannot control the temperature in different zones. The temperature inside the box is also affected by the external ambient temperature, and there are many cold spots and hot spots, which makes the internal temperature unstable and difficult to control, and the temperature uniformity is relatively poor, making it difficult to meet the use requirements. Utility Model Content

[0004] The utility model aims to provide a temperature control system for an enzyme substrate method quantitative disk incubator, which improves the temperature uniformity of each vertical surface of the internal space of the incubator and simultaneously forms the internal airflow into circulating wind so as to make the temperature of the internal space of the incubator uniformly circulate.

[0005] In order to solve the above technical problems, the utility model provides a temperature control system for an enzyme substrate method quantitative disk incubator, comprising a main frame and a plurality of heating plates arranged on each vertical surface of the main frame, so that the main frame and the plurality of heating plates surround a constant temperature space, and a plurality of temperature sensors are installed inside the constant temperature space, and the plurality of temperature sensors are respectively used to detect the temperature of each vertical surface.

[0006] Furthermore, a heat preservation plate is arranged on the outer side of the heating plate.

[0007] Furthermore, a plurality of fan groups are arranged at the top of the constant temperature space, and the air inlets of the plurality of fan groups are all oriented toward the top horizontal plane of the constant temperature space, and the air outlets of the plurality of fan groups are all oriented toward the lower part of the constant temperature space.

[0008] Furthermore, a single fan group includes at least two fans.

[0009] Furthermore, a front panel is arranged at the front of the main frame, a front door is rotatably mounted on the front panel, and a transparent window is provided on the front door.

[0010] Furthermore, a through slot is provided on the front door, and the through slot is used to install a window, and the through slot passes through the heating plate and the insulation plate located at the front panel.

[0011] Furthermore, a heat conducting plate is provided on a side of the heating plate located at the front panel away from the heat preservation plate.

[0012] Furthermore, a sealing ring is provided on the inner edge of the front door so that the heating plate and the insulation plate located at the front panel are connected to one side of the front door through the sealing ring.

[0013] The beneficial effect of the utility model is that when it is necessary to control the temperature inside the constant temperature space, the temperature of each facade is detected separately by a number of temperature sensors, and then the temperature of a number of heating plates is raised to different degrees according to the different temperature feedback information of different facades, so that the temperature of each facade after heating is finally uniform, thereby avoiding the situation where multiple cold spots and hot spots appear in the constant temperature space, which leads to uneven temperature inside the constant temperature space. At the same time, in the subsequent process of maintaining the constant temperature, real-time detection can also be carried out by various temperature sensors, and then the heating temperature of the heating plate corresponding to each facade can be adjusted in real time to ensure a long-term constant temperature effect.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

Therefore, the above terms should not be understood as limiting the present invention.

[0021] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0022] like Figure 1-4 The utility model provides a temperature control system for an enzyme substrate method quantitative disk incubator, comprising a main frame 1 and a plurality of heating plates 2 arranged on each vertical surface of the main frame 1, so that the main frame 1 and the plurality of heating plates 2 surround a constant temperature space, wherein a plurality of temperature sensors 3 are installed inside the constant temperature space, and the plurality of temperature sensors 3 are respectively used to detect the temperature of each vertical surface.

[0023] When it is necessary to control the temperature inside the constant temperature space, the temperature of each facade is detected separately through a number of temperature sensors, and then the temperature of several heating plates is increased to different degrees according to the different temperature feedback information of different facades, so that the temperature of each facade is unified after the heating, thereby avoiding the situation where multiple cold spots and hot spots appear in the constant temperature space, which leads to uneven temperature inside the constant temperature space. At the same time, in the subsequent process of maintaining the constant temperature, real-time detection can also be carried out through various temperature sensors, and then the heating temperature of the heating plates corresponding to each facade can be adjusted in real time to ensure a long-term constant temperature effect.

[0024] It is worth mentioning that this solution is used in conjunction with a PLC system, which controls the temperature of each heating plate individually to ensure that the overall temperature of each position is uniform.

[0025] In a preferred embodiment of the present solution, the temperature sensor uses a 12-channel PT100 thermal resistance temperature sensor.

[0026] Preferably, a heat preservation plate 4 is provided on the outer side of the heating plate 2 so that the heat preservation plate can maintain the temperature inside the constant temperature space to prevent heat from escaping.

[0027] Among them, the insulation board adopts aluminum foil polyurethane insulation board.

[0028] Preferably, a plurality of fan groups 5 are arranged at the top of the constant temperature space, and the air inlets of the plurality of fan groups are all oriented toward the top horizontal plane of the constant temperature space, and the air outlets of the plurality of fan groups 5 are all oriented toward the lower part of the constant temperature space.

[0029] Specifically, the airflow at the top of the constant temperature space is sucked in through a plurality of fan groups, and the airflow is discharged to the lower part of the constant temperature space, so that the airflow inside the constant temperature space forms a circulation flow, thereby driving the overall temperature inside the constant temperature space to be uniform.

[0030] In an embodiment of the present solution, a single fan group 5 includes at least two fans.

[0031] Preferably, a front panel 6 is provided at the front of the main frame 1 , a front door 7 is rotatably mounted on the front panel 6 , and a transparent window 8 is provided on the front door 7 .

[0032] Specifically, the condition of the culture in the constant temperature space can be directly observed through the viewing window, and when the culture needs to be taken out or put in, the front door can be opened for taking or putting.

[0033] Among them, the windows adopt a hollow glass structure.

[0034] Preferably, a through slot 9 is provided on the front door 7 , and the through slot 9 is used to install the viewing window 8 , and the through slot 9 passes through the heating plate 2 and the insulation plate 4 located at the front panel 6 .

[0035] Specifically, by setting the through groove, the heating plate and the insulation plate will not block the position of the window, thereby ensuring the observation effect of the window. At the same time, the periphery of the window is also insulated and heated to prevent heat from escaping from the installation position of the window.

[0036] In one embodiment of the present solution, a heat conducting plate 10 is provided on a side of the heating plate 2 located at the front panel 6 away from the heat preservation plate 4 .

[0037] Preferably, a sealing ring 11 is provided on the inner edge of the front door 7 so that the heating plate 2 and the insulation plate 4 located at the front panel 6 are connected to one side of the front door 7 through the sealing ring 11 .

[0038] Specifically, the position of the front door is further sealed by a sealing ring, thereby improving the sealing effect of the front door, the heating plate and the insulation plate, thereby improving the insulation effect.

[0039] In the actual use of this solution, the following process can be adopted:

[0040] After actual measurement, the cold spot temperature is on the left side of the constant temperature space, and the hot spot temperature is on the right side of the constant temperature space. For the cold spot, a local heating plate is used to increase the control temperature. Each temperature sensor corresponds to a nearby heating plate, and the control temperature of the cold spot is set to +10°C of the required temperature. At the same time, the heating plates of the remaining facades are turned on, and the heating temperature is the required temperature +5°C. When the temperature rises to the required temperature -2°C, the control temperature is adjusted until the detection temperature of each facade reaches the required temperature setting value. When the temperature on the left is detected to be low, the temperature of the left heating plate is appropriately increased. When the temperature on the right is detected to exceed the set value, the temperature of the right heating plate is appropriately lowered. When the overall temperature reaches the required set temperature, the heating plate is relied on to provide continuous heat energy for the incubator to ensure temperature uniformity.

[0041] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
