Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a temperature-controllable warm water sample detection chamber. Background Art

[0002] After the sewage enters the sewage treatment plant, it is first filtered through a coarse screen to remove large impurities; then it is filtered through a fine screen to remove small impurities in the sewage; then the filtered sewage is sequentially processed through a grit chamber, a biochemical tank, a high-density tank, and a disinfection tank, and finally discharged into the water body. Before the sewage is discharged into the water body, the water quality needs to be tested to ensure that the water quality meets the standards.

[0003] The appropriate range of water temperature for water quality testing should be controlled between 20 and 25 degrees. In water quality testing, water temperature is a parameter that cannot be ignored. Water temperature has different degrees of influence on many physical and chemical parameters. Too high or too low water temperature will affect the results of water quality testing, which may lead to errors or even failures. Some existing water quality testing devices are not convenient for controlling the temperature of water quality samples, and the test results have large errors, which have certain shortcomings.

DETAILED DESCRIPTION

[0022] 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 without creative work are within the scope of protection of the utility model.

Heat dissipation port 1208 is arranged at the gap of heat sink 1203, and dustproof net is arranged on heat dissipation port 1208.

[0025] Analysis of the above content: The cooling liquid in the detection chamber 1 is cooled by the semiconductor refrigeration sheet 1201. The heat generated by the semiconductor refrigeration sheet 1201 is transferred to the heat sink 1203 by the heat conducting plate 1202, and heat is exchanged with the air through the heat sink 1203, thereby dissipating the heat of the semiconductor refrigeration sheet 1201 and ensuring the cooling efficiency of the semiconductor refrigeration sheet 1201. The fan blade 1205 is driven to rotate by the high-speed motor 1204 to accelerate the air flow speed at the heat sink 1203, thereby improving the heat dissipation effect of the heat sink 1203. A dustproof net is set to prevent dust from being sucked into the detection chamber 1, and to prevent dust from falling on the heat sink 1203, resulting in poor heat dissipation. The water quality sample to be tested is added into the test tube 4, and the temperature of the coolant is adjusted by the cooperation of the heating tube 1206 and the semiconductor refrigeration sheet 1201, so as to control the temperature of the sample in the test tube 4 to ensure that the temperature is within a suitable range, and the water quality is tested by the test probe 10 to check whether the water quality is qualified (the test probe 10 is an existing test equipment probe, and the test probe 10 is replaced accordingly according to the test object, which will not be elaborated here).

[0026] Embodiment 2:

[0027] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the controller 14 is electrically connected to the heating tube 1206, the temperature sensor 1207 and the high-speed motor 1204 respectively, and the heating tube 1206 and the detection tube 4 do not contact each other.

[0034] Analysis of the above content: The detection tube 4 is covered by the sliding cover 7 to prevent dust from falling into the detection tube 4 and causing detection errors when the detection tube 4 is not in use. The cooperation between the magnet bar 5 and the iron sheet ensures that the sliding cover 7 is always located above the detection tube 4, thereby sealing the detection tube 4. When detection is required, the sliding cover 7 can be removed by moving the shifting block 8.

[0035] Embodiment five:

[0036] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: a stirring assembly 11 is arranged in the detection bin body 1, and the stirring assembly 11 includes a driven stirring blade 1101, and the driven stirring blade 1101 is rotatably connected to the bottom of the detection tube 4. A motor 1102 is fixedly installed at the bottom of the detection bin body 1, and an active roller stirring blade 1103 is fixedly connected to the output shaft end of the motor 1102.

[0037] Analysis of the above content: The active roller stirring blade 1103 is driven to rotate by the motor 1102, and the driven stirring blade 1101 is also driven to rotate under the action of magnetic force. The coolant in the detection chamber 1 is circulated by the rotation of the active roller stirring blade 1103, thereby ensuring the uniform temperature of the coolant in the detection chamber 1 and the accuracy of temperature control. Some tests require the addition of specific liquid medicine to the water quality, and the sample in the detection tube 4 is rotated by the rotation of the driven stirring blade 1101 to increase the speed of liquid medicine dissolution.

The active roller stirring blade 1103 and the driven stirring blade 1101 are connected by magnetic force to avoid setting a transmission structure at the bottom of the detection tube 4. The structure is relatively simple, and the active roller stirring blade 1103 and the driven stirring blade 1101 can be set to be magnet materials that attract each other.
