Description

Technical Field

[0001] The invention belongs to the field of ceramic product production, in particular to a temperature cycle test system for ceramic products, and relates to a ceramic production temperature cycle technology. Background Art

[0002] During the ceramic firing process, it is often necessary to accurately control the temperature and air pressure in the kiln. Too high a kiln temperature or too high an air pressure will affect the quality of the finished ceramic products. However, the current kilns lack effective temperature monitoring measures, which causes ceramics to be fired for too long at inappropriate temperatures, resulting in product quality problems. There is a lack of effective monitoring and implementation measures. At the same time, traditional ceramic kiln temperature measurement often uses a single signal as the transmission data when detecting temperature, and has weak temperature control capabilities. For different ceramic products, it is impossible to select the most suitable firing temperature by comparing multiple data. Therefore, we need to propose a new design solution. Summary of the invention

[0003] The object of the present invention is to provide a temperature cycle test system for ceramic products.

[0004] The technical problems solved by the present invention are:

[0005] (1) How to specifically control the temperature through a heating signal or a cooling signal, cut off the power supply of the compressor and connect the power supply of the evaporator when receiving the heating signal, cut off the power supply of the condenser and connect the power supply of the heater after a first preset time, cut off the power supply of the evaporator and connect the power supply of the compressor when receiving the cooling signal, cut off the power supply of the heater and connect the power supply of the condenser after a second preset time, and transmit the signal to the staff in a timely manner so as to facilitate the subsequent process;

[0006] (2) How to select the most suitable firing temperature for different ceramic products, collect and compare multiple data, and fire the ceramic products at the appropriate temperature.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A temperature cycle test system for ceramic products, comprising an execution unit for changing temperature, a heating unit for generating a heating signal, a cooling unit for generating a cooling signal, a temperature monitoring unit for monitoring the temperature of the execution unit, and a control unit for generating an execution signal;

[0009] Among them, the control unit, the execution unit, the heating unit, the refrigeration unit and the temperature monitoring unit are all connected in communication. The control unit generates an execution signal based on the temperature of the execution unit and the temperature of the previous cycle. The heating unit and the refrigeration unit are both connected to the execution unit. The heater is used to heat the liquid delivered to the load device by the circulation system. The condenser is used to exchange heat with the plant water to condense the gas in the refrigeration system pipeline. When the compressor is working, the gas enters the condenser, and then enters the evaporator after condensation. After heat exchange in the evaporator, the temperature rises and finally returns to the compressor. The temperature control device realizes precise temperature control through different control methods of the load device under different states. Since the heater only works when the temperature rises rapidly and does not work in normal temperature control, the device achieves energy saving while realizing precise temperature control.

[0010] The heating unit and the cooling unit generate a heating signal or a cooling signal based on the received execution signal and send it to the execution unit. The execution unit performs temperature control based on the heating signal or the cooling signal. The temperature monitoring unit is connected to the execution unit to record the current cycle temperature.

[0011] Furthermore, the current cycle temperature is specifically a temperature spectrum difference within a preset time period, wherein the temperature spectrum difference is the difference between the highest temperature within the preset time period and the temperature with the highest frequency of occurrence, the previous cycle temperature is specifically a temperature spectrum difference within the previous preset time period, and the execution signal includes a first execution signal and a second execution signal, and the control unit generates an execution signal based on the temperature of the execution unit and the previous cycle temperature, specifically including the following steps: obtaining the current round temperature and the previous cycle temperature; calculating the cycle difference between the current round temperature and the previous cycle temperature, and the sum of the cycle difference and the highest temperature in the current round temperature; judging whether the ratio of the cycle difference to the sum of the highest temperature in the current round temperature to the highest temperature in the previous cycle temperature satisfies a preset relationship, and if so, a first execution signal is generated, otherwise, a second execution signal is generated.

[0012] Furthermore, the preset relationship is specifically:

[0013] If the ratio is <1.1, a first execution signal is generated;

[0014] If the ratio is ≥1.1, a second execution signal is generated;

[0015] The first execution signal is first encoded by a first encoder, and the heating unit includes a first decoder, which is used to decode the first encoding; the second execution signal is second encoded by a second encoder, and the refrigeration unit includes a second decoder, which is used to decode the second encoding.

[0016] Furthermore, the execution unit includes a heater, an evaporator, a heat exchanger, a compressor and a condenser, wherein the heater and the condenser are both connected to the heat exchanger, the heat exchanger is connected to the load device, the compressor is connected to the condenser, the evaporator is connected to the heater, and the execution unit performs temperature control based on the heating signal or the cooling signal specifically as follows:

[0017] When a heating signal is received, the power supply of the compressor is cut off and the power supply of the evaporator is connected. After the first preset time, the power supply of the condenser is cut off and the power supply of the heater is connected. When a cooling signal is received, the power supply of the evaporator is cut off and the power supply of the compressor is connected. After the second preset time, the power supply of the heater is cut off and the power supply of the condenser is connected. The first preset time is the sum of the time required for heater preheating and self-testing; the second preset time is the sum of the time required for condenser precooling and self-testing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) By setting a temperature monitoring unit and a control unit, the cycle difference between the current round of temperature and the previous cycle of temperature, as well as the sum of the cycle difference and the highest temperature in the current round of temperature are calculated; it is determined whether the ratio of the sum of the cycle difference and the highest temperature in the current round of temperature to the highest temperature in the previous cycle of temperature satisfies a preset relationship. If it satisfies the preset relationship, a heating signal is executed to cut off the condenser power supply and turn on the heater power supply; if it does not satisfy the preset relationship, a cooling signal is executed to cut off the heater power supply and turn on the condenser power supply; by automatically adjusting heating and cooling, the firing temperature of ceramic products is controlled, the error rate of ceramic products is reduced, and the production quality of ceramic products is improved;

[0020] (2) By measuring the temperature of multiple cycles and selecting the appropriate temperature, the firing temperature of ceramic products is controlled during the heating process, and the most suitable firing temperature is selected to improve the control over the firing of ceramic products.
