Description

Technical Field

[0001] This utility model relates to the field of jet cleaning for mineral processing machines, and in particular to a novel jet cleaning device for mineral processing machines. Background Technology

[0002] A coal ore separator, also known as a coal ore separator, is a key piece of equipment in the coal washing and processing technology. Its core purpose is very clear: to efficiently and automatically separate useful coal (clean coal) from useless ore (a type of blackish-gray rock that is associated with coal seams during the coal formation process) and other impurities from the mined raw coal.

[0003] When the mineral processing machine is working, it needs to be purged. However, the solenoid valves used in the existing purging device are expensive and large in size, which means that only a limited number of solenoid valves can be installed in the purging device. This will affect the purging efficiency. In addition, when the purging device is shut down, there is no protective structure for its internal chambers, which can easily cause damage and blockage inside the purging device.

[0004] Therefore, it is necessary to propose a new type of injection device for mineral processing machines to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a novel jetting device for mineral processing machines, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel jetting device for a mineral processing machine includes a device body, a sealed chamber, and a jetting assembly. The device body is installed on one side of the sealed chamber, the jetting assembly is installed on the other side of the sealed chamber, and a jetting nozzle is installed on the top of the jetting assembly. An electromagnetic valve is installed in the inner cavity of the sealed chamber, a throttle valve is installed on the top of the sealed chamber, a manifold assembly is installed on the side of the inner cavity of the sealed chamber, and a first manifold groove is formed on the outer wall of the manifold assembly.

[0007] Preferably, air inlets are symmetrically installed at both ends of the device body away from the sealing chamber, the air inlets are connected to the inner cavity of the sealing chamber, and a controller is installed at the bottom of the sealing chamber to control the solenoid valve.

[0008] Preferably, one end of the solenoid valve communicates with the inner cavity of the sealing chamber, and the other end of the solenoid valve is installed on the side of the ejection assembly. The ejection assembly has a connecting groove, a second manifold groove and a connecting groove on the side near the sealing chamber.

[0009] Preferably, the solenoid valve communicates with the inner cavity of the connecting groove, and a negative pressure cleaning groove is provided between the connecting groove and the second manifold groove, with the inner cavities of the connecting groove and the second manifold groove communicating through the negative pressure cleaning groove.

[0010] Preferably, the top of the ejection assembly has an air outlet, and the inner cavity of the ejection assembly has a through groove that communicates with a connecting groove. The through groove and the connecting groove are "L" shaped, and the negative pressure cleaning groove is located at the top of the inner cavity of the connecting groove.

[0011] Preferably, the number of solenoid valves and the number of first manifolds are the same. The solenoid valves only include valve cores and do not have pipes. The solenoid valves have at least nine air outlets on the side near the first manifold. The positions of the air outlets and the manifold components are corresponding. An air outlet groove is provided in the center of the inner cavity of the first manifold. The first manifold is used to collect the air discharged from the air outlets at the air outlet groove. The sealing chamber is connected to the inner cavity of the connecting groove through the air outlet groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This new type of injection device for mineral processing machines, with its solenoid valve as the valve core, lacks the common valve body shell and pipes. During installation, it can effectively improve space utilization and reduce the cost of the device. Through the setting of the first confluence channel and the air outlet channel, the air discharged from the solenoid valve can be collected in one place, so that the gas pressure of the ejected gas is greater, which can effectively improve the injection efficiency. This new type of jet cleaning device for mineral processing machines features a connecting trough and a through trough. The connecting trough receives air discharged from the solenoid valve, allowing the air to pass through the through trough and then exit through the nozzle, thus completing the jet cleaning operation. A throttling valve, when activated by the solenoid valve, allows some gas to enter the throttling valve's cavity from the sealed chamber. The throttling valve then directs the gas into the connecting trough's cavity. This, combined with the connecting trough and negative pressure cleaning trough, blows the gas outward from the through trough and connecting trough, preventing dust and debris from entering the through trough's cavity through the outlet. When the solenoid valve closes and the outlet returns air, the through trough and connecting trough are under negative pressure, preventing dust and debris from entering deep into the sealed chamber and reducing the flow rate of dust and debris. This prevents wear on the pipes in the jet cleaning components, effectively extending their service life. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-4 As shown, a novel injection device for a mineral processing machine includes a device body 1, a sealed chamber 2, and an injection assembly 3. The device body 1 is installed on one side of the sealed chamber 2, and the injection assembly 3 is installed on the other side of the sealed chamber 2. A nozzle 1 is installed on the top of the injection assembly 3. A solenoid valve 7 is installed inside the sealed chamber 2, and a throttle valve 4 is installed on the top of the sealed chamber 2. A manifold assembly 8 is installed on the side of the sealed chamber 2, and a first manifold groove 9 is formed on the outer wall of the manifold assembly 8. Air inlets 5 are symmetrically installed at both ends of the device body 1 away from the sealed chamber 2, and the air inlets 5 communicate with the inner cavity of the sealed chamber 2. A controller 6 is installed at the bottom of the sealed chamber 2, and the controller 6 controls the solenoid valve 7. One end of the solenoid valve 7 communicates with the inner cavity of the sealed chamber 2, and the other end of the solenoid valve 7 is installed on the side of the injection assembly 3. A connecting groove 17, a second manifold groove 15, and a connecting groove 14 are formed on the side of the injection assembly 3 closest to the sealed chamber 2. 7 communicates with the inner cavity of the connecting groove 17. A negative pressure cleaning groove 16 is provided between the connecting groove 14 and the second manifold 15. The inner cavities of the connecting groove 14 and the second manifold 15 are connected through the negative pressure cleaning groove 16. An air outlet 12 is provided at the top of the spraying component 3. A through groove 13 is provided in the inner cavity of the spraying component 3. The through groove 13 is connected to the connecting groove 14. The through groove 13 and the connecting groove 14 are "L" shaped. The negative pressure cleaning groove 16 is located at the top of the inner cavity of the connecting groove 14. The number of solenoid valves 7 and the first manifold 9 are the same. The solenoid valve 7 only includes the valve core and does not have a pipe. At least nine air outlets are provided on the side of the solenoid valve 7 near the first manifold 9. The positions of the air outlets and the manifold 8 are corresponding. An air outlet groove 10 is provided in the center of the inner cavity of the first manifold 9. The first manifold 9 is used to collect the air discharged from the air outlets in the air outlet groove 10. The sealing chamber 2 is connected to the inner cavity of the connecting groove 14 through the air outlet groove 10. The solenoid valve 7, being a valve core, lacks the common valve body casing and piping, effectively improving space utilization and reducing device cost during installation. The first manifold 9 and outlet 10 collect the gas discharged from the solenoid valve 7, increasing its pressure and improving blowing efficiency. The connecting groove 14 receives the gas discharged from the solenoid valve 7, allowing the gas to enter through the outlet 13 and then exit through the nozzle 11, thus completing the blowing operation. The throttling valve 4, when the solenoid valve 7 is activated, allows a portion of the gas to escape from the sealing chamber 2. The gas enters the inner cavity of the throttle valve 4. At this time, the throttle valve 4 can input the gas into the inner cavity of the connecting groove 17. Therefore, in conjunction with the connecting groove 17 and the negative pressure cleaning groove 16, the gas in the through groove 13 and the connecting groove 14 can be blown outward, which can prevent dust and debris from entering the inner cavity of the through groove 13 through the air outlet 12. When the solenoid valve 7 is closed and the air outlet 12 returns gas, the inner cavity of the through groove 13 and the connecting groove 14 can be in a negative pressure state, which can also prevent dust and debris from entering the deep inner cavity of the sealing chamber 2. At the same time, it can reduce the flow rate of dust and debris, and prevent wear on the pipes in the ejection assembly 3, thus effectively improving its service life.

[0017] It should be noted that this utility model is a new type of spraying device for a mineral processing machine. When in use, the air pump is connected to the air inlet 5, and the device body 1 is installed at the position where spraying is required. After the air pump is started, the gas enters the inner cavity of the sealing chamber 2 through the air inlet 5. The solenoid valve 7 is started to input the gas into the inner cavity of the first confluence channel 9. After the gas flows back through the outlet channel 10, it is uniformly input into the inner cavity of the connecting channel 14. After being discharged into the outlet 12 through the channel 13, the spraying operation can be carried out. When the solenoid valve 7 is activated, a portion of the gas will enter the connecting groove 17 through the throttle valve 4, and then enter the through groove 13 through the negative pressure cleaning groove 16. This can prevent the entry of dust and debris. When the solenoid valve 7 is closed, the remaining gas in the inner cavity of the sealing chamber 2 will still enter the inner cavity of the through groove 13 through the throttle valve 4, thus forming a negative pressure state, which can minimize the entry of dust and debris.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
