Description

Technical Field

[0001] The invention relates to the technical field of coal mine blasting, in particular to a device for simultaneously removing dust and eliminating CO during blasting. Background Art

[0002] With the increasing demand for mining of resources such as coal, blasting technology is widely used in mining and other fields. However, a large amount of dust and harmful gases will be generated during the blasting process, among which CO is an extremely dangerous gas. At present, blasting operations are facing severe environmental challenges. On the one hand, the large amount of dust not only affects the vision of the operators and reduces work efficiency, but also long-term exposure will cause serious harm to the health of the operators, such as causing occupational diseases such as pneumoconiosis. On the other hand, the presence of CO poses a huge threat to the life safety of the operators.

[0003] In traditional blasting operations, a single method of dust removal or CO treatment is often used, which has limited effect and cannot solve both problems at the same time. In addition, the existing CO eliminators have strict requirements on the use environment due to their characteristics and are difficult to be directly applied to the high-temperature and high-dust concentration working face environment of blasting. Therefore, it is of great practical significance to develop a device that can simultaneously remove dust and eliminate CO during blasting.

When the temperature is appropriate in the presence of CO, the explosion-proof electromagnetic valve is opened to spray a mist catalyst solution to efficiently adsorb CO, thereby providing a device for simultaneously removing dust and eliminating CO during blasting.

[0033] 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.

[0034] As shown in the accompanying drawings, a device for simultaneously removing dust and eliminating CO during blasting of the present invention comprises:

[0035] A mobile trolley 1 can move on the ground, and a horizontal mounting surface is also provided on the mobile trolley 1;

[0036] The liquid storage tank 2 is arranged on the mounting surface of the mobile vehicle 1, wherein the liquid storage tank 2 comprises a water tank 21 and a catalyst solution tank 22, both of which are fixedly mounted on the mounting surface of the mobile vehicle 1, wherein the water tank 21 is filled with a dust removal solution, and the catalyst solution tank 22 is filled with a catalyst solution for eliminating CO;

[0037] The nozzle assembly 3 is arranged on the mounting surface of the mobile vehicle 1;

[0038] The liquid pumping assembly 4 is arranged on the mounting surface of the mobile vehicle 1 and is interconnected with the liquid storage tank 2 and the nozzle assembly 3;

[0039] The sensor assembly 5 is disposed on the mounting surface of the mobile vehicle 1 and is electrically connected to the liquid extraction assembly 4 .

[0040] The core carrier of the device is a mobile trolley 1, which can walk freely on the ground of blasting operation 1. With its flexible mobility, it can quickly reach the working area. A horizontal mounting surface is designed on the top of the mobile trolley 1. This design provides a stable and convenient platform for the installation of subsequent components. On the mounting surface, a liquid storage tank 2 is fixedly installed, which is further subdivided into two independent parts: a water tank 21 and a catalyst solution tank 22. The water tank 21 is pre-filled with a solution for dust removal. After spraying, these solutions can quickly combine with dust particles in the air to achieve the effect of dust removal, while the catalyst solution tank 22 is filled with a catalyst solution specifically used to eliminate CO. After contacting with CO gas, this solution can undergo a chemical reaction to convert toxic CO into harmless substances. In order to effectively spray the solution in the liquid storage tank 2 to the working area, the device is also equipped with a nozzle assembly 3, which is also installed on the mounting surface of the mobile trolley 1. The design of the nozzle assembly 3 ensures the uniform spraying of the solution, thereby improving the efficiency of dust removal and CO elimination. In order to achieve automatic In order to realize the transportation of CO, a pumping assembly 4 is provided in the device, one end of which is connected to the liquid storage tank 2, and the other end is connected to the nozzle assembly 3, so as to form a complete transportation system. When the solution needs to be sprayed, the pumping assembly 4 will be started to extract the solution in the liquid storage tank 2 and spray it to the working area through the nozzle assembly 3. In order to improve the intelligence level of the device, a sensor assembly 5 is also provided. The sensor assembly 5 is installed on the explosion-proof battery 9 and is electrically connected to the pumping assembly 4. The sensor assembly 5 can monitor the CO concentration and the ambient temperature. When it is detected that CO is generated on the working face and the temperature is appropriate, the sensor assembly 5 will send a signal to the explosion-proof solenoid valve 47 to instruct it to open, so as to realize the dust removal and elimination of CO in the working area at the same time. In summary, the device realizes the function of dust removal and elimination of CO at the same time during blasting operation through the flexible movement of the mobile trolley 1, the partitioned storage of the liquid storage tank 2, the uniform spraying of the nozzle assembly 3, the automatic transportation of the pumping assembly 4 and the intelligent monitoring of the sensor assembly 5, which greatly improves the safety and environmental protection of the operation.

[0041] In a preferred embodiment of the present invention, the following configuration can be further adopted: a handle 6 is fixedly mounted on the mounting surface of the mobile trolley 1. During blasting operation, when the device needs to be moved to a new operating area, the operator can hold the handle 6 and push the mobile trolley 1 to move by manpower. This manual pushing method is not only simple and direct, but also can ensure that the mobile trolley 1 maintains a stable moving trajectory in a complex and changeable operating environment. At the same time, the presence of the handle 6 also enhances the operator's control over the mobile trolley 1. When an emergency stop or change of the moving direction is required, the operator can quickly adjust the motion state of the mobile trolley 1 by holding the handle 6, thereby ensuring the safety and efficiency of the operation. During the operation of the device, the handle 6 does not directly participate in the dust removal and CO elimination operations, but it is an important component to ensure that the entire device can be flexibly and safely moved to the designated operating area. By holding the handle 6, the operator can easily push the mobile trolley 1 to quickly arrive at the operating site to prepare for subsequent dust removal and CO elimination operations.

[0042] In a preferred embodiment, the present invention can be further configured as follows: the water tank 21 and the catalyst solution tank 22 are two independent and non-interconnected containing boxes, wherein the volume ratio between the water tank 21 and the catalyst solution tank 22 is 2:1. The main function of the water tank 21 is to store a solution for dust removal. In blasting operations, dust is one of the main pollutants, and the dust removal solution can effectively combine with dust particles to make them settle down, thereby achieving the effect of dust removal. Since dust removal operations usually require a large amount of solution to cover and wet the operating area, the volume of the water tank 21 is designed to be relatively large to ensure sufficient solution supply. The catalyst solution tank 22 is used to store a catalyst solution specifically used to eliminate CO. After this solution comes into contact with CO gas, it can undergo a chemical reaction to convert toxic CO into harmless substances. Since the concentration of CO is usually high, the water tank 21 is relatively large. The reaction efficiency of the catalyst solution is low, and the reaction efficiency of the catalyst solution is high, so the volume of the catalyst solution tank 22 is relatively small, but it is still sufficient to meet the demand for eliminating CO. It is worth noting that the dependent claims clearly stipulate that the volume ratio between the water tank 21 and the catalyst solution tank 22 is 2:1. This ratio is determined based on the actual needs of dust removal and CO elimination in blasting operations. During the operation of the device, the water tank 21 and the catalyst solution tank 22 are respectively connected to the nozzle assembly 3 through the pumping assembly 4. When the sensor assembly 5 detects that CO is generated on the working surface and the temperature is appropriate, the sensor assembly 5 will send a signal to the explosion-proof solenoid valve 47 to spray water mist first and then spray the catalyst solution, so as to effectively remove dust and eliminate CO. Since the water tank 21 and the catalyst solution tank 22 are independent, they can replace and maintain the solutions separately without interfering with each other.

[0043] In a preferred embodiment, the present invention can be further configured as follows: the nozzle assembly 3 includes:

[0044] The bracket 31 is fixedly mounted on the mounting surface of the moving trolley 1, and is perpendicular to the mounting surface of the moving trolley 1;

[0045] Two superchargers 32 are fixedly mounted on the surface of the bracket 31, wherein the two superchargers 32 are arranged in an up-and-down arrangement; and

[0046] The nozzles 33 are arranged in two groups in equal numbers. The two groups of nozzles 33 are respectively distributed on the surfaces of the two boosters 32 and are interconnected with the boosters 32. The bracket 31, as the supporting structure of the nozzle assembly 3, is firmly fixed on the mounting surface of the mobile trolley 1 and is arranged perpendicular to the mounting surface. This design ensures that the nozzle assembly 3 can be stably suspended above the mobile trolley 1, providing precise positioning and stable spraying direction for the spraying of the solution. The booster 32 is the power source in the nozzle assembly 3. There are two of them, both of which are fixedly installed on the surface of the bracket 31 and arranged up and down. This layout not only optimizes the space utilization, but also enables the solution to be pressurized by the booster 32 and then sprayed out from the nozzle 33 at a higher speed and pressure, thereby enhancing the coverage and penetration ability of the solution. The nozzle 33 is the final spray of the solution. There are several nozzles, which are equally divided into two groups and distributed on the surfaces of the two superchargers 32 respectively. Each group of nozzles 33 is interconnected with the corresponding supercharger 32, ensuring that the solution can flow smoothly into the nozzle 33 after being pressurized, and be sprayed out at its set spray angle and flow rate. This design not only improves the spraying efficiency of the solution, but also makes the spraying range more uniform, covering a wider working area. During the working process, the liquid extraction component 4 extracts the corresponding solution from the liquid storage tank 2. After the solution is transported by the liquid extraction component 4, it enters the two superchargers 32 respectively. Under the pressurization of the supercharger 32, the solution is given a higher speed and pressure, and then is evenly sprayed to the working area in the form of atomization through the nozzle 33. This spraying method not only improves the dust removal and CO elimination effect, but also reduces the waste of solution and ensures the effective use of resources.

[0047] In a preferred embodiment of the present invention, the nozzles 33 can be further configured as follows: the nozzles 33 are divided into two types: the nozzles located on the upper supercharger 32 are high-pressure spray nozzles for mining, and the nozzles located on the lower supercharger 32 are small-sized spray nozzles for mining. This design is based on the needs of dust removal and CO elimination in blasting operations. The high-pressure spray nozzles for mining located on the upper side can withstand higher pressures, so they can spray out finer and denser droplets. These droplets can quickly combine with dust particles in the air to form larger particles and settle down, thereby achieving an efficient dust removal effect. The small-sized spray nozzles for mining located on the lower side can Characterized by its smaller size and lower spray pressure, this nozzle can produce a softer spray effect and is suitable for eliminating CO. Due to the explosion-proof solenoid valve 47 controlled by the sensor assembly 5, water mist is first sprayed to contact the high-temperature air mass and dust mass for cooling and dust removal, providing a good elimination environment for the catalyst solution with a short spray distance, thereby achieving CO elimination. Through the coordinated work of these two different types of nozzles 33, the nozzle assembly 3 can provide a more accurate and efficient spray effect according to the dust removal and CO elimination needs of different areas. This design not only improves operating efficiency, but also reduces solution waste and ensures effective use of resources.

[0048] In a preferred embodiment, the present invention can be further configured as follows: the liquid extraction component 4 includes:

[0049] A first liquid pump 41 is fixedly mounted on the mounting surface of the mobile vehicle 1, and a water suction pipe 42 is fixedly mounted on its water suction end, one end of which penetrates and extends into the water tank 21, wherein a water outlet pipe 43 is fixedly mounted on the water delivery end of the first liquid pump 41, and the other end of the water outlet pipe 43 is connected to the upper supercharger 32; and

[0050] The second liquid pump 44 is fixedly mounted on the mounting surface of the mobile trolley 1, and a catalyst liquid pumping pipe 45 having one end penetrating and extending into the catalyst solution tank 22 is fixedly mounted on the water suction end of the second liquid pump 44, wherein a catalyst liquid infusion pipe 46 is fixedly mounted on the water delivery end of the second liquid pump 44, and the other end of the catalyst liquid infusion pipe 46 is interconnected with the lower supercharger 32, and an explosion-proof electromagnetic valve 47 is also arranged on the catalyst liquid infusion pipe 46. The liquid pumping assembly 4 is a key component in the device, and its design fully considers the needs of dust removal and CO elimination in blasting operations. The assembly mainly includes a first liquid pump 41 and a second liquid pump The liquid pumps 44 are responsible for extracting solutions from the water tank 21 and the catalyst solution tank 22, respectively, and conveying them to the booster 32 in the nozzle assembly 3. The first liquid pump 41 is fixedly mounted on the mounting surface of the mobile vehicle 1, and its water suction end is connected to the water tank 21 through the water suction pipe 42. When the first liquid pump 41 is started, it will suck the dust removal solution in the water tank 21 through the water suction pipe 42, and convey the solution to the upper booster 32 through the outlet pipe 43 connected to its water delivery end. After receiving the solution, the upper booster 32 will pressurize it, and then pass the nozzle 33 on its surface to The second pump 44 is also fixedly mounted on the mounting surface of the mobile trolley 1, and its water suction end is connected to the catalyst solution tank 22 through the catalyst suction pipe 45. When the second pump 44 is started, it will suck the catalyst solution in the catalyst solution tank 22 through the catalyst suction pipe 45, and deliver the solution to the lower supercharger 32 through the catalyst infusion pipe 46 connected to its water delivery end. An explosion-proof solenoid valve 47 is also provided on the catalyst infusion pipe 46 to achieve the delay of the injection. The lower supercharger 32 receives the catalyst solution in the catalyst solution tank 22 through the catalyst suction pipe 45. After the catalyst solution arrives, it will also be pressurized and then sprayed into the working area in the form of a spray through the nozzle 33 on its surface to react chemically with the CO gas in the air to achieve the effect of eliminating CO. During operation, the liquid extraction component 4 will intelligently start or shut down the second liquid extraction pump 44 according to the monitoring results of the sensor component 5 to meet the needs of dust removal and CO elimination in different working areas. At the same time, the setting of the explosion-proof solenoid valve 47 also increases the safety and reliability of the entire device, ensuring that no accidents will occur due to excessive pressure or high temperature when transporting the catalyst solution.

[0051] In a preferred embodiment, the present invention can be further configured as follows: the sensor assembly 5 includes:

[0052] A CO concentration sensor 51 is fixedly mounted on the explosion-proof battery 9; and

[0053] The temperature sensor 52 is fixedly mounted on the explosion-proof battery 9. The sensor assembly 5 is an intelligent monitoring component in the device. Its design fully considers the complexity and safety requirements of the blasting working environment. The assembly mainly includes a CO concentration sensor 51 and a temperature sensor 52, both of which are fixedly mounted on the explosion-proof battery to ensure that the CO concentration and temperature in the working environment can be accurately and real-time monitored. The CO concentration sensor 51 can capture the CO gas molecules in the working environment in real time through its highly sensitive detection element, and convert them into electrical signals for transmission. When the CO concentration in the working environment exceeds the preset safety threshold, the CO concentration sensor 51 will immediately send a signal to the explosion-proof solenoid valve 47, and the temperature sensor 52 will send a signal to the explosion-proof solenoid valve 47 through its internal The thermistor in the part can sense the temperature change of the working environment in real time and convert it into corresponding electrical signals for transmission. The sensor component 5 detects the CO concentration and the ambient temperature at the same time. The purpose is that the explosion-proof solenoid valve 47 cannot be opened when only CO is produced, because the CO catalytic solution will be inactivated when the temperature is too high. When the temperature sensor 52 detects that the temperature is appropriate after the water mist dust removal and cooling, the CO concentration sensor 51 and the temperature sensor 52 jointly control the explosion-proof solenoid valve 47 to open, and when the CO sensor 51 detects that there is no CO concentration on the working surface, the explosion-proof solenoid valve 47 will be closed, and the catalyst solution will no longer be sprayed continuously. The CO concentration sensor 51 and the temperature sensor 52 are both provided with a fixed value to control the explosion-proof solenoid valve 47 to open after it is met.

[0054] In a preferred embodiment of the present invention, the following configurations can be further adopted: a liquid injection port 7 is provided on the surface of the water tank 21 and the catalyst solution tank 22, and a dustproof air inlet net 8 is also embedded on the surface of the water tank 21 and the catalyst solution tank 22. The water tank 21 and the catalyst solution tank 22 are key components in the device, and are responsible for storing the dust removal solution and the catalyst solution for extraction by the liquid extraction component 4 and transporting them to the nozzle component 3 for spraying. In order to meet the needs of actual operations, the design of the two boxes fully considers ease of use, safety and durability. First, a liquid injection port 7 is provided on the surface of the water tank 21 and the catalyst solution tank 22. The design of the liquid injection port 7 allows the operator to conveniently It is convenient to add solution to each box through it without disassembling or moving the box, which not only improves the convenience of operation, but also reduces the risk of box damage and solution leakage caused by frequent disassembly. In actual operation, the operator can add dust removal solution to the water tank 21 through one of the injection ports 7, and add catalyst solution to the catalyst solution tank 22 through the other injection port 7 as needed to ensure the continuous operation and efficient operation of the device. Secondly, a dust-proof air inlet net 8 is embedded on the surface of the water tank 21 and the catalyst solution tank 22. The main functions of the dust-proof air inlet net 8 are one to prevent dust, and the other to maintain pressure balance in the box when pumping liquid.

[0055] The specific working principle of the device for simultaneously removing dust and eliminating CO during blasting is as follows:

[0056] First, the operator needs to move the device to the blasting operation area, which is achieved by the walking function of the mobile trolley 1. The design of the mobile trolley 1 enables it to move easily on the ground, and the horizontal mounting surface provided on it provides stable support for other components;

[0057] Before the operation begins, the operator needs to fill the dust removal solution and the catalyst solution for eliminating CO into the two storage tanks through the liquid injection ports 7 on the surface of the water tank 21 and the catalyst solution tank 22. The water tank 21 and the catalyst solution tank 22 are two independent and non-interconnected containing boxes, which ensure the purity of the solution and non-interference. At the same time, the volume ratio of the two boxes is 2:1 to adapt to the amount of solution used under different operation requirements;

[0058] After filling the solution, the operator can start the device. The first liquid pump 41 extracts the dust removal solution from the water tank 21 through the water suction pipe 42 and transports it to the upper supercharger 32 through the water outlet pipe 43. After the upper supercharger 32 pressurizes the solution, it is sprayed to the working area in the form of high-pressure spray through the mining high-pressure spray nozzle 33 on its surface to achieve the dust removal effect. The sprayed water mist first contacts the high-temperature air mass and the dust mass to cool down and remove the dust, providing a good elimination environment for the catalyst solution with a short spray distance;

[0059] In addition, the CO concentration sensor 51 and the temperature sensor 52 in the sensor assembly 5 will start to monitor the CO concentration and temperature in the working environment in real time. The sensors detect the CO concentration and the ambient temperature. When the temperature sensor 52 detects that the temperature is appropriate after the water mist cools down, the CO concentration sensor 51 and the temperature sensor 52 jointly control the explosion-proof electromagnetic valve 47 to open. At this time, the second liquid pump 44 will extract the catalyst solution from the catalyst solution tank 22 through the catalyst liquid extraction pipe 45, and transport it to the lower supercharger 32 through the catalyst liquid delivery pipe 46. After the lower supercharger 32 pressurizes the catalyst solution, it is sprayed into the working area in the form of a spray through the small mining spray nozzle 33 on its surface, and chemically reacts with the CO gas in the air to achieve the effect of eliminating CO.

[0060] During the whole operation process, the operator can conveniently push the mobile trolley 1 through the handle 6 to flexibly move the device in the operation area to meet the needs of dust removal and CO elimination at different locations. At the same time, the explosion-proof battery 9 provides stable power support for the device to ensure the normal operation of all electronic components.

[0061] When the operation is finished, the operator can turn off the device and clean and maintain the water tank 21 and the catalyst solution tank 22 through the liquid injection port 7 for next use. The dustproof air intake net 8 effectively prevents external dust and impurities from entering the box, maintaining the cleanliness and purity of the solution.

[0062] In summary, the device, through its ingenious design and intelligent control, achieves the functions of dust removal and CO elimination during blasting operations, providing a strong guarantee for the safety and health of operators.
