Description

Technical Field

[0001] The invention relates to the technical field of gas detection, and in particular to an encoder cleaning system. Background Art

[0002] In modern industry, encoders are widely used in various automation equipment to detect parameters such as position, speed and direction. However, during long-term operation, encoders are susceptible to harmful gases in the air, which may damage the precision components of the encoder and cause equipment failure. Therefore, it is particularly important to ensure the cleanliness and normal operation of the encoder.

[0003] In the prior art, common encoder cleaning methods mainly include manual cleaning and simple mechanical cleaning. However, these methods have obvious shortcomings. Manual cleaning requires a lot of manpower, is inefficient, and cannot guarantee the consistency of the cleaning effect. At the same time, secondary damage may be caused to the encoder during operation. Although simple mechanical cleaning reduces labor costs, its cleaning effect is also unsatisfactory, especially when facing complex toxic gas pollution, the existing mechanical cleaning equipment is difficult to deal with effectively. In addition, the prior art lacks means for detecting and treating toxic gases, which makes it impossible for the encoder to monitor and purify harmful gases in the air in real time during the cleaning process, thereby affecting the cleaning effect and the safety of the equipment.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-7 , the present invention provides a technical solution: including a gas detection module, a receiving module, a controller module and an exhaust device, the system introduces the identified toxic gas into the exhaust device, and the exhaust device purifies the toxic gas before discharging it;

[0050] Wherein, the gas detection module is used to detect the concentration of harmful gases discharged during the cleaning process and send the detection results to the receiving module;

[0051] The receiving module is used to receive the detection data sent by the gas detection module, encode the detection data through a specific encoding algorithm, and generate a coded signal containing information such as gas type and concentration;

[0052] The controller module is used to receive the coded signal sent by the receiving module, parse the gas type and concentration information, and generate a control signal to send to the exhaust module according to the preset processing strategy and control algorithm;

[0053] The exhaust device receives the control signal sent by the controller module, and adjusts the operating state of the exhaust device according to the control signal to achieve the purification and discharge of harmful gases. The cleaning mechanism is arranged below the exhaust device and is used to clean the encoder;

[0054] The exhaust port of the cleaning mechanism is communicated with the interface of the exhaust device.

[0055] It should be noted that: a custom encoding program is set in the receiving module;

[0056] There are three types of gases we detect: methane (CH4), carbon monoxide (CO) and hydrogen sulfide (H2S). Each gas has a unique ID and the concentration is represented by an 8-bit unsigned integer (0-255)

[0057] Gas type code:

[0058] Methane (CH4): ID = 001

[0059] Carbon monoxide (CO): ID = 010

[0060] Hydrogen sulfide (H2S): ID = 100

[0061] These IDs can be represented by 3-bit binary numbers.

[0062] Concentration Code:

[0063] The concentration is represented by an 8-bit binary number ranging from 0 to 255. For example, if the detected methane concentration is 123, the concentration is encoded as 01111011.

[0064] Coding example:

[0065] Assuming that the gas detection module detects that the methane concentration in the air is 123, we need to generate a coded signal according to the above procedure.

[0066] Gas type code: The ID of methane is 001.

[0067] Concentration coding: The concentration of methane is 123, coded as 01111011.

[0068] Combining the two, we get an 11-bit coded signal: 00101111011.

[0069] Data transmission: This coded signal can be sent to the controller module via serial communication (such as UART, SPI, etc.) or other communication methods. After receiving the signal, the controller module will decode it according to the same protocol to obtain the gas type and concentration information.

[0070] Controller module processing: After receiving the coded signal, the controller module will decode it according to the protocol to obtain the gas type (methane) and concentration (123). Then, it will generate a corresponding control signal and send it to the exhaust device according to the preset processing strategy and control algorithm. For example, if the methane concentration exceeds the preset safety threshold, the controller may send a signal to the exhaust device to increase the exhaust volume to quickly exhaust the harmful gas.

[0071] It should be further explained that: in the actual encoding process of concentration coding, there are measurement errors or noises. We can add a check bit to the concentration data, and the check bit adopts parity check;

[0072] Check digit

[0073] After the gas type code and the concentration code, a check bit is added to check the integrity of the data, which can be achieved by calculating the checksum of the data field, parity check or other methods.

[0074] Message Format

[0075] A complete message can include the following parts:

[0076] Start byte: used to mark the beginning of a message, such as a fixed ASCII character or binary sequence.

[0077] Gas type code: 4-bit binary number.

[0078] Concentration code: 8 binary digits, plus 1 check digit.

[0079] End byte: used to mark the end of the message, corresponding to the start byte.

[0080] Coding Example

[0081] Assume that the gas detection module detects that the methane concentration in the air is 123, and we use even parity.

[0082] Gas type code: The ID of methane is 0010 (extension bit is reserved).

[0083] Concentration encoding: The concentration of methane is 123, encoded as 01111011, and the even parity bit (obtained by calculation) is 0.

[0084] Complete message (assuming the start byte is 0xAA and the end byte is 0xBB): 0xAA 0010 0111101100xBB

[0085] See also Figure 1 - Figure 7 , the exhaust equipment includes an exhaust hood 1 and a purification box 7;

[0086] The exhaust hood 1 comprises a grille plate 2 mounted on the exhaust hood 1, an exhaust pipe 3 is mounted on the top of the exhaust hood 1, an exhaust passage 4 for gas circulation is arranged inside the exhaust pipe 3, a wind wheel 6 is rotatably mounted inside the exhaust passage 4, and a driving motor 5 for driving the wind wheel 6 to rotate is also mounted inside the exhaust passage 4;

The first purification chamber 12 and the second purification chamber 13 are filled with activated carbon particles for filtering toxic gases. The partition 11 is provided with a first vent hole 14 connecting the first purification chamber 12 and the second purification chamber 13, and the inner diameter of the first vent hole 14 is larger than the diameter of the activated carbon particles.

[0088] A valve channel 15 is provided in the partition 11, a valve plate 16 is airtightly slidably provided in the valve channel 15, a return spring is installed on the inner side wall of the valve channel 15, one end of the return spring away from the valve channel 15 is connected to the valve plate 16, and second vent holes 35 are provided on the valve plate 16 corresponding to the first vent holes 14 one by one, the valve plate 16 can reciprocate horizontally along the inner wall of the valve channel 15 to adjust the size of the connecting portion of the second vent hole 35 and the first vent hole 14, and a driving component for controlling the horizontal reciprocating motion of the valve plate 16 is provided on the side wall of the purification box 7;

[0089] Specifically, by driving the wind wheel 6 to rotate through the driving motor 5, a negative pressure can be generated inside the exhaust channel 4, so that the external gas can enter the exhaust channel 4 through the exhaust hood 1, and then be transported to the interior of the purification box 7 through the exhaust channel 4. The gas entering the purification box 7 passes through the first air vent 14 and the second air vent 35 and then enters the first purification chamber 12 and the second purification chamber 13.

[0090] By utilizing the natural airflow of the gas to push the activated carbon particles filled in the first purification chamber 12 and the second purification chamber 13 into a suspended state, the contact area and contact time between the gas and the activated carbon particles can be significantly increased, and they can be more evenly distributed in the airflow, so that harmful substances in the gas can more comprehensively undergo adsorption reactions with the activated carbon, thereby improving the efficiency and effect of gas purification; ensuring full utilization of the activated carbon: the activated carbon can continuously move and disperse in a suspended state, which helps prevent the accumulation and blockage of the activated carbon particles and maintain its good adsorption performance. At the same time, since the activated carbon particles can be more evenly distributed in the airflow, its adsorption capacity can also be more fully utilized, extending the service life of the activated carbon and reducing the frequency and cost of replacing the activated carbon.

[0091] See also Figure 4 and Figure 5 The driving assembly includes a fixed plate 23 mounted on the side wall of the purification box 7, a driving shaft 24 is rotatably mounted on the fixed plate 23, and a servo motor 25 for driving the driving shaft 24 to rotate is fixedly mounted on the bottom surface of the fixed plate 23;

[0092] A shaft sleeve 19 is fixedly mounted on the outer wall of the servo motor 25, a turntable 20 is fixedly mounted on the outer wall of the shaft sleeve 19, a swing rod 22 is adjustably mounted on the outer wall of the turntable 20, an extension plate 17 is fixedly mounted on one side of the valve plate 16 extending to the outside of the purification box 7, a roller 18 is rotatably mounted on the extension plate 17, and the elastic force of the return spring pushes the valve plate 16 and the extension plate 17 to slide toward the outside of the purification box 7, so that the roller 18 and the swing rod 22 are always in a state of abutment;

[0093] Specifically, the servo motor 25 can drive the driving shaft 24 to rotate, and the driving shaft 24 can drive the shaft sleeve 19 installed on the outer wall thereof to rotate, and the shaft sleeve 19 drives the turntable 20 and the swing rod 22 installed on the turntable 20 to rotate. The swing rod 22 can drive the roller 18 to drive the extension plate 17 to move synchronously in the process of following the rotation of the turntable 20, thereby achieving the effect of the valve plate 16 sliding back and forth horizontally inside the valve channel 15;

[0094] The reciprocating sliding of the valve plate 16 can drive the size of the connecting portion between the second air vent 35 installed thereon and the first air vent 14 to be reciprocatedly adjusted, thereby causing the gas flow rate entering the first purification chamber 12 and the second purification chamber 13 to change reciprocatingly, thereby causing the activated carbon particles inside the first purification chamber 12 and the second purification chamber 13 to be in a reciprocating suspension state, further increasing the contact area between the gas and the activated carbon.

[0095] See also Figure 4 and Figure 5 A rotating shaft 21 is rotatably mounted on the rotating disk 20, a swing rod 22 is rotatably mounted on the rotating shaft 21, a driven pinion 26 is fixedly mounted on the outer wall of the top of the rotating shaft 21, a driving large gear 27 meshingly connected with the driven pinion 26 is sleeved on the outer wall of the shaft sleeve 19, and a locking nut 28 for pressing the driving large gear 27 is threadedly connected on the outer wall of the shaft sleeve 19;

[0096] Specifically, the driving gear 27 can be unlocked by rotating the locking nut 28, so that the driving gear 27 can rotate on the shaft sleeve 19, and the driven gear 26 meshing with the driving gear 27 can be driven to rotate, and the driven gear 26 drives the rotating shaft 21 and the swing rod 22 to rotate, thereby achieving the effect of adjusting the rotation of the swing rod 22. The distance between the swing rod 22 and the rotating disk 20 can be changed by adjusting the swing rod 22, and the stroke of the horizontal reciprocating sliding of the valve plate 16 can be adjusted;

[0097] When the activated carbon particles inside the first purification chamber 12 and the second purification chamber 13 are in a saturated state, the rocker arm 22 is adjusted to the maximum stroke, and then the valve plate 16 is moved to the deepest position. At this time, the first air hole 14 and the second air hole 35 are in an overlapping state. In this state, the activated carbon particles inside the first purification chamber 12 and the second purification chamber 13 can be discharged from the first air hole 14 and the second air hole 35.

[0098] See also Figure 1 and Figure 6 The purification box 7 is composed of a wide square section, a middle funnel section and a narrow square section which are integrally formed at the top, the middle and the bottom. An exhaust passage 9 is arranged on the wide square section at the upper end of the purification box 7. A dustproof net 10 is arranged inside the exhaust passage 9. An air inlet passage 8 which is connected to the exhaust passage 4 is arranged inside the narrow square section. A first baffle 29 and a second baffle 33 which can be opened or closed relative to the narrow square section are arranged in the narrow square section. When the first baffle 29 is in an open state and the second baffle 33 is in a closed state, it is a gas purification processing state. When the first baffle 29 is in a closed state and the second baffle 33 is in an open state, the active gas inside the first purification chamber 12 and the second purification chamber 13 can be cleaned. The carbon particles are replaced; a discharge port 32 is provided on the side wall of the narrow square section, and a second baffle 33 is slidably connected to the inside of the discharge port 32.

A first electric telescopic rod 31 for controlling the horizontal sliding of the connecting strip 30 is fixedly installed on the side wall of the purification box 7; the first baffle 29 is inclined, and the bottom end of the first baffle 29 corresponds to the port at the lower end of the discharge port 32;

[0099] Specifically, by setting a certain slope of the first baffle 29, when the first baffle 29 is in a closed state and the second baffle 33 is in an open state, the activated carbon particles inside the first purification chamber 12 and the second purification chamber 13 will fall on the surface of the first baffle 29 and then be discharged from the discharge port 32 to replace the activated carbon.

[0100] Specifically, the purification box is provided with a finned heat sink, a thermoelectric battery connected to the finned heat sink, a collector connected to the thermoelectric battery, a negative ion generator connected to the collector, and a voltage regulator connected to the negative ion generator. The finned heat sink is mainly used to increase the heat dissipation area and improve the heat dissipation effect. As a key component for the thermoelectric battery group to absorb heat from the heat source, the collector directly determines the hot end temperature of the thermoelectric battery. Therefore, it is necessary to analyze the temperature distribution on the surface of the collector through simulation, and further calculate the open circuit voltage of the thermoelectric battery to determine the number of thermoelectric batteries required. The collector consists of a collector box and fins. The structure of the collector box is a flat aluminum alloy structure with a size of 400 mm×100mm×100 mm. The front and back of the collector box are connected to connect the dry exhaust gas outlet and the exhaust gas purification chamber; the four outer wall surfaces of the collector box are in contact with the hot end of the thermoelectric battery to heat the hot end of the thermoelectric power generation module, and the fins play a role in enhancing the heat collection effect.

[0101] The thermoelectric cell obtains the heat difference of the external environment through the finned heat sink and generates electricity. The electricity is transmitted to the negative ion generator through the collector, and the negative ion generator uses electricity to generate negative ions to purify the air. The voltage stabilizer is used to adjust and stabilize the input voltage of the negative ion generator to ensure its stable operation. The purification box realizes efficient heat energy utilization and electricity conversion through the combination of finned heat sink, thermoelectric cell and collector. The negative ion generator effectively improves the air purification effect, and the voltage stabilizer ensures the stable operation of the system, thereby improving the overall performance and reliability of the purification box.

[0102] Finned heat sinks can be replaced with other forms of heat sinks, such as water-cooled heat sinks, to adapt to different usage environments and needs. Thermoelectric batteries can also be selected in different types according to different working environments, such as semiconductor thermoelectric batteries. Negative ion generators and voltage stabilizers can be selected in different models and specifications according to actual needs to achieve a better system configuration.

[0117] 2. Calculate the control signal:

[0118] ;

[0119] In summary, the calculation formula of the control algorithm function is: ;

[0120] in, and Based on the type of gas and concentration From the preset processing strategy The control parameters extracted from

[0121] Through the control algorithm, the corresponding adjustment coefficient and concentration threshold are found through the control parameter matrix according to different gas types and their corresponding concentration ranges. When the gas concentration is within the specified range, the control signal is calculated through the adjustment coefficient, and the control signal is linearly related to the concentration. This control signal is used to adjust the working state of the purification equipment to effectively control the gas concentration and maintain the ambient air quality. The above control algorithm realizes precise control of the concentration of multiple gases by introducing the control parameter matrix. Its linear relationship simplifies the calculation process and improves the response speed and control accuracy. By setting different concentration thresholds and adjustment coefficients, the algorithm can adapt to a variety of complex environments, greatly improving the intelligence level and adaptability of the air purification system.

[0122] Working principle: through the provision of gas detection module, receiving module, controller module and exhaust equipment; the gas detection module detects the type and concentration of gas in the environment in real time through the gas sensor, and transmits the detection signal to the receiving module; the receiving module encodes the received detection signal to generate a digital signal containing information such as gas type and concentration; the controller module determines the gas condition in the current environment according to the digital signal output by the receiving module, and intelligently adjusts the operating parameters of the exhaust equipment, such as exhaust speed and exhaust time, to achieve efficient and energy-saving exhaust processing, and drives the wind wheel 6 to rotate by the driving motor 5, so that negative pressure can be generated inside the exhaust channel 4, so that the external gas can enter the exhaust channel 4 through the exhaust hood 1, and then be transported to the inside of the purification box 7 by the exhaust channel 4. The gas entering the purification box 7 passes through the first vent 14. , and then enter the interior of the first purification chamber 12 and the second purification chamber 13 through the second air vent 35; by utilizing the natural airflow of the gas to push the activated carbon particles filled in the first purification chamber 12 and the second purification chamber 13 into a suspended state, the contact area and contact time between the gas and the activated carbon particles can be significantly increased, and they can be more evenly distributed in the airflow, so that the harmful substances in the gas can be more comprehensively adsorbed by the activated carbon, thereby improving the efficiency and effect of gas purification; ensuring full utilization of the activated carbon: the activated carbon can continuously move and disperse in a suspended state, which helps to prevent the accumulation and blockage of the activated carbon particles and maintain its good adsorption performance. At the same time, since the activated carbon particles can be more evenly distributed in the airflow, its adsorption capacity can also be more fully utilized, extending the service life of the activated carbon and reducing the frequency and cost of replacing the activated carbon.

[0123] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
