Description

Technical Field

[0001] The utility model relates to the technical field of cotton moisture and drying temperature, and in particular to an automatic monitoring and control device for seed cotton moisture regain and temperature. Background Art

[0002] The moisture regain of seed cotton is very critical in the cotton ginning process. Moisture regain is an important factor affecting the quality of cotton processing. Different technological links in cotton processing have different requirements for moisture regain.

[0003] In the process of seed cotton drying, drying temperature and moisture regain are the biggest factors affecting the length of cotton fibers. If the moisture regain of seed cotton is too high, the adhesion between impurities and fibers will increase, and impurities will be difficult to remove. Not only will it be difficult to clean, affecting the smooth entry of seed cotton into the cotton ginning box, but it may also form lumps and cause blockage, damage the cotton gin or stop the cotton ginning process completely; if the moisture regain of seed cotton is too low, the strength of the fiber will decrease, the cotton fiber will become brittle, the amount of short fibers will increase, and the quality of cotton will be seriously affected. At the same time, the seed cotton will adhere to the metal surface, generating static electricity in the fiber, causing mechanical blockage or shutdown.

[0004] The current situation is affected by technical means and human factors. On the one hand, it is difficult to record data manually in a continuous, complete and accurate manner. On the other hand, due to the complexity of the relationship between the moisture regain of seed cotton (6.5% to 8.5%) and the drying temperature, manual adjustment of parameters or indirect estimation methods are not real-time and accurate, and it is difficult to achieve dynamic control, thus affecting the normal operation of the entire processing and production.

[0032] Combine the following Figure 1 , some embodiments of the present utility model are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The utility model provides an automatic monitoring and control device for moisture regain and temperature of seed cotton, which comprises a controller 3, a heat preservation box 1 and an automatic seed cotton feeder 2; an air supply channel 6 is arranged in the heat preservation box 1, a heater 8 and a temperature sensor 9 are arranged in the air supply channel 6, an air supply device 4 is arranged at the air inlet of the air supply channel 6, and an air outlet 7 of the air supply channel 6 is arranged corresponding to the automatic seed cotton feeder 2; a moisture collector 11 is arranged in the automatic seed cotton feeder 2; the controller 3 is respectively connected to the heater 8, the air supply device 4, the temperature sensor 9 and the moisture collector 11.

[0034] In this embodiment, the seed cotton is placed in the automatic seed cotton feeding machine 2, and the moisture of the seed cotton is taken away by blowing air into the automatic seed cotton feeding machine 2 through the heat preservation box 1, so as to adjust the moisture regain of the seed cotton.

[0035] In this embodiment, the temperature of the cotton seeds is automatically monitored by the temperature sensor 9, and after the monitoring result is transmitted to the controller 3, the controller 3 performs analysis and comparison. When the temperature value transmitted by the temperature sensor 9 does not meet the standard, the controller 3 controls the heater 8 to turn on, and uses the heater 8 to heat the air passing through the heat preservation box 1, and the heated air is sent to the seed cotton automatic feeder 2 to dry the seed cotton.

[0036] Specifically, in this embodiment, the controller 3 detects the outlet air temperature of the heat preservation box 1 through the temperature sensor 9, and then adjusts the air supply temperature by controlling the heater 8, and controls the air supply speed of the air supply device 4 to adjust the moisture regain of the seed cotton.

[0037] Furthermore, a wind speed collector, an air volume collector and a temperature collector are provided at the air outlet 7 of the air supply channel 6 .

[0038] Specifically, different information collectors 10 are provided at the air outlet 7 of the air supply channel 6 to collect different information. For example, a wind speed collector is provided at the air outlet 7 of the air supply channel 6 to collect the air speed at the air outlet 7, a wind volume collector is provided at the air outlet 7 of the air supply channel 6 to collect the air volume at the air outlet 7, and a temperature collector is provided at the air outlet 7 of the air supply channel 6 to collect the air temperature at the air outlet 7.

[0039] After different parameters are collected by different information collectors 10, the controller 3 controls the heater 8 and the air supply device 4 according to the moisture regain requirement of the seed cotton, so that the moisture regain of the seed cotton in the automatic seed cotton feeding machine 2 automatically reaches the target value.

[0040] It should be pointed out that in the present embodiment, a wind speed collector, an air volume collector and a temperature collector are provided at the air outlet 7, but they are not limited to these information collectors 10. Different information collectors 10 can also be provided according to different requirements. For example, a humidity sensor can be added as a humidity information collector 10, etc. As long as the controller 3 can control the air outlet parameters according to the corresponding parameters, the moisture regain requirement of the seed cotton of the automatic seed cotton feeding machine 2 can be finally achieved.

[0041] Furthermore, the heater 8 is an electric heating device.

[0042] Electric heating has the advantages of fast heating speed and stable heating temperature, and the heating temperature is easy to adjust, which can better control the temperature of the flowing gas in the air supply channel 6.

[0043] Specifically, in this embodiment, the electric heating device is an electric heating rod.

[0044] It should be pointed out that in the present embodiment, the heater 8 is an electric heating rod, but it is not limited to electric heating rods, it can also be an electric heating plate, etc., that is, as long as it can heat the flowing gas in the air supply channel 6 of the insulation box 1 by electric heating.

[0045] It should also be pointed out that, in the present embodiment, the heater 8 is an electric heating device, but it is not limited to electric heating, and it can also be other heating methods, such as water heating, that is, heat exchange through hot water to achieve the heating purpose, and chemical heating, etc. In other words, as long as the heater 8 can heat the flowing gas in the air supply channel 6, it will be fine.

[0046] Furthermore, the number of the heaters 8 is multiple groups, and the multiple groups of heaters 8 are distributed along the wind flow direction of the air supply channel 6.

[0047] In this embodiment, the number of heaters 8 is multiple groups, which are distributed along the wind flow direction of the flowing gas in the air supply channel 6.

[0048] Specifically, the distribution mode may be a linear distribution or a spiral distribution.

[0049] Such an arrangement can increase the heating time of the flowing gas, so that the temperature of the flowing gas increases faster, thereby facilitating the adjustment of the gas temperature at the air outlet 7.

[0050] In this embodiment, the heating temperatures of the multiple heaters 8 can be the same or different. When the same temperature is set, the heaters 8 are all set to the same heating value, and the flowing gas is heated to the same temperature; when the heating temperatures of the heaters 8 are different, the heating temperature of the heater 8 near the air inlet 5 is lower than the heating temperature of the heater 8 near the air outlet 7, so that the flowing gas is gradually heat exchanged, further improving the heat exchange efficiency and reducing the waste of heat energy.

[0051] Furthermore, the temperature sensor 9 is arranged between two adjacent groups of heaters 8 .

[0052] Specifically, in this embodiment, a temperature sensor 9 is provided between two adjacent groups of heaters 8, which can detect the temperature of the heater 8 each time it is heated, and enable the controller 3 to make timely adjustments to the subsequent heaters 8 according to the heating conditions of each group to meet the requirements of the outlet air temperature.

[0053] Furthermore, an isolation cover 12 is provided on the heat preservation box body 1 , and the isolation cover 12 is used to isolate and protect the connecting wires outside the heat preservation box body 1 .

[0054] In this embodiment, after the isolation cover 12 is provided on the insulation box 1, the internal temperature can be reduced from being dissipated outward, thereby preventing the temperature of the insulation box 1 from affecting the power cords of devices such as the heater 8, temperature sensor 9, and information collector 10, thereby ensuring the service life of the power cords.

[0055] Furthermore, there are multiple moisture collectors 11.

[0056] Specifically, in this embodiment, a pair of moisture collectors 11 are provided to realize rapid collection of moisture from seed cotton and improve the adjustment efficiency of moisture regain of seed cotton.

[0057] Further, more specifically, in this embodiment, the moisture collector 11 is arranged on the inner wall of the automatic seed cotton feeder 2 .

[0058] The moisture collector 11 is arranged on the inner wall of the seed cotton automatic flower feeder 2, so as to facilitate the discharge of the collected moisture to the outside.

[0059] Furthermore, the air supply device 4 is a fan.

[0060] In this embodiment, a fan is used as the air supply device 4 to supply air to the air supply channel 6 in the heat preservation box 1 , and the wind speed of the fan can be controlled by the controller 3 .

[0061] It should be pointed out that, in the present embodiment, the air supply device 4 is a blower, but it is not limited to a blower, and it can also be other devices, that is, as long as it can blow the heated gas flowing in the heat preservation box 1 into the automatic seed cotton feeder 2.

[0062] Furthermore, an air inlet filter 13 is provided at the entrance of the air supply channel 6 .

[0063] By providing the air inlet filter 13, the flowing air passing through the air supply channel 6 can be made relatively clean, thereby reducing the entry of dust and other debris into the seed cotton, thereby ensuring the cleanliness of the seed cotton.

[0064] In this embodiment, the controller 3 is also connected to a data display for displaying the monitored data in real time.

[0065] In this embodiment, the controller 3 is also connected to an input device for inputting required parameters into the controller 3 , and then controlling each component through the controller 3 .

[0066] In this embodiment, an alarm device is also connected to the controller 3. When the data shows abnormality, the controller 3 controls the alarm device to sound an alarm so that the operator can check and eliminate the fault in time.

[0067] Specifically, in the present embodiment, the filter screen 13 at the air inlet 5 can be configured as a multi-layer filter screen 13 with certain gaps between the multi-layer filter screens 13, which can further improve the cleanliness of the air.

[0068] It can be seen from the above that the automatic monitoring and control device for moisture regain and temperature of seed cotton provided by the utility model can realize automatic monitoring of moisture regain of seed cotton, and perform real-time adjustment and control according to the data of automatic monitoring, and can also realize automatic monitoring and control of seed cotton temperature, and perform real-time adjustment and control according to the data of automatic monitoring. The specific monitoring and control process is as follows:

[0069] The power supply is connected to the heater 8 through a wire to convert electrical energy into thermal energy. After the heater 8 is powered on, the thermal energy emitted by the heater 8 exchanges heat with the cold air delivered by the air supply device 4. The cold air of the air supply device 4 passes through the hot air channel with the temperature heater 8 at a uniform speed. After the cold air exchanges heat with the heater 8, it becomes high-temperature air, which is delivered to the air outlet 7 of the air supply channel 6. The high-temperature air is further delivered to the automatic seed cotton feeding machine 2. The seed cotton moisture collector 11 installed on the side of the automatic seed cotton feeding machine 2 cooperates with the information collectors 10 such as the air volume collector, wind speed collector and temperature collector at the air outlet 7 of the air supply channel 6 to transmit the data to the controller 3. The wind speed, air volume and temperature are automatically adjusted by the controller 3. The requirements of the moisture regain and drying temperature of the seed cotton can be achieved without manual intervention, thereby ensuring the cotton processing quality while improving the production efficiency.

[0070] The utility model uses a temperature sensor 9, a hot air velocity meter, a hot air volume flow meter, and a seed cotton moisture collector 11 to perform scientific statistical analysis on the data collected according to a certain mathematical model, and accurately calculates the dynamic drying temperature and moisture regain of the seed cotton, thereby ensuring the cotton processing quality and improving the production efficiency.

[0071] It can be seen from the above that the utility model has the following advantages compared with the prior art:

[0072] Instead of manual labor, the dynamic moisture regain of seed cotton can be automatically monitored reliably and continuously for a long time, and the data can be backed up and queried; the seed cotton moisture collector 11 is set with multiple sampling points, and the collected data is scientifically statistically analyzed according to a certain mathematical model. The data is more representative and can accurately calculate the real-time moisture regain and real-time drying temperature in the seed cotton production process; the seed cotton moisture regain (6.5% to 8.5%) and drying temperature (120°C to 170°C) are automatically and accurately adjusted according to the set operating parameters, ensuring the cotton processing quality while improving production efficiency.

[0073] The beneficial effects of the embodiments of the utility model are:

[0074] The moisture regain of the seed cotton is monitored and controlled by data transmission between the controller 3 and the moisture collector 11 in the seed cotton feeder, and the temperature of the seed cotton is monitored and controlled by data transmission between the controller 3 and the heater 8 and the temperature sensor 9 in the heat preservation box 1, thereby achieving the purpose of dynamically controlling the moisture regain and temperature of the seed cotton, thereby improving the production efficiency during cotton processing.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
