Description

Technical Field

[0001] The invention belongs to the technical field of water impurity removal, and in particular relates to a maintenance-free reverse flushing water impurity removal device with multiple gears. Background Art

[0002] During coal mining, tunneling and tunnel construction, dust generation needs to be suppressed. Spraying water mist on the mining site is the first step in dust reduction. The water used for spraying is also the water for equipment cooling. Since spraying dust reduction needs to form water mist, the diameter of the nozzle water channel is very fine, and the cleanliness of the water is required to be high. The water entering the inner cavity of the equipment also needs to be kept clean. The clean supply of water is very important in the application of coal mining equipment.

[0003] Before and after being pumped out, water must pass through the filter element to remove impurities and provide the system with clean water that has been removed of impurities. During use, the reverse flushing water impurity removal device needs to maintain the impurity removal effect and smooth flow. When water flows through the filter element, the removed impurities will adhere to the outer wall of the filter element. After a period of use, the filter element channel will be blocked. At this time, the filter element needs to be removed and replaced or cleaned. Frequent replacement or removal of the filter element affects production efficiency and increases labor intensity. Some cleanable impurity removers have complex structures and cumbersome operations. The original system design must be changed during installation.

[0042] Reference Figure 3As shown, an outer cavity 502 is formed between the outer shell 2 and the inner shell 3, an isolation cavity 501 is formed on the inner shell 3, the isolation ring 5, the filter element 4 and the side of the inner shell 3 away from the base 1, and an inner cavity 503 is formed between the inner shell 3, the isolation ring 5, the filter element 4 and the base 1; a plurality of water inlets include a first water inlet 101, a main water inlet 103 and a secondary water inlet 102, the first water inlet 101 is opened at the end of the base 1 and is connected to the water pump, which is the water inlet of the device, the main water inlet 103 and the inner shell 3 are connected to the water pump, and the water inlet 102 is connected to the water pump. The secondary water inlet 102 is connected to the outer cavity 502; the multiple sewage outlets include a first sewage outlet 104, a second sewage outlet 105 and a third sewage outlet 106, the first sewage outlet 104 is opened at the end of the base 1, the second sewage outlet 105 is connected to the sewage channel of the inner cavity 503, and the third sewage outlet 106 is connected to the sewage channel of the outer cavity 502. The base 1 is also provided with a mounting hole 107 for installing a maintenance-free reverse flushing water impurity removal device with multiple gears.

[0043] In order to ensure that the water medium can flow between the multiple chambers, a plurality of through holes 301 are provided on the inner shell 3 at positions corresponding to the isolation chambers 501 .

[0044] When the device is in normal impurity removal state, refer to Figure 3 and Figure 4 As shown, when the extension direction of the control mechanism is the same as the extension direction of the shell 2, the main channel 1101 connects the first water inlet 101 and the main water inlet 103, and the secondary water inlet 102 is connected to the secondary channel 1102. The water medium enters from the first water inlet 101, and enters the inner cavity 503 and the outer cavity 502 through the main water inlet 103 and the secondary water inlet 102 respectively. The water medium flows out from the inner cavity 503 through the filter element 4 and the output flange 7. The water medium enters the isolation cavity 501 from the outer cavity 502 through the through hole 301, and flows out from the output flange 7 through the filter element 4. Specifically, when the direction of the arrow 10 is the same as the extension direction of the housing 2, the handle 8 is in the initial position. At this time, the main channel 1101 of the water supply ball valve 11 is connected to the first water inlet 101 and the main water inlet 103 of the base 1, and the secondary water inlet 102 of the base 1 is connected to the secondary channel 1102. The water medium enters from the first water inlet 101 and flows through the water supply ball valve 11 in two ways. One way enters the inner cavity 503 through the main water inlet 103, and then removes impurities along the inner cavity 503 through the filter element 4, and flows out from the output flange 7 to the subsequent pipeline of the system. Figure 4 As shown, the water medium in the other path enters the outer cavity 502 through the secondary channel 1102 and the secondary water inlet 102, and the water medium in the outer cavity 502 enters the isolation cavity 501 through the through hole 301. After the impurities in the water medium in the isolation cavity 501 are removed by the filter element 4, it merges with the water medium after the impurities are removed in the previous path and enters the subsequent pipeline. This process realizes the removal of impurities in the water medium.

[0045] When the device is in the off state, refer to Figure 5 and Figure 6 As shown, the control mechanism rotates 90° clockwise, perpendicular to the extension direction of the housing 2, and the main channel 1101 is perpendicular to the first water inlet 101, and is in a closed state. Specifically, the handle 8 rotates the knob 9 clockwise 90° from the normal impurity removal state position, and the arrow 10 now points to a position perpendicular to the extension direction of the device, and the main channel 1101 is not connected to the first water inlet 101, which is equivalent to the water inlet of the device being in a closed state, and the water medium cannot enter the device, and the device does not work. When the arrow 10 points to this position, the filter element 4 can be replaced, or the device can be repaired.

[0046] The filter element 4 includes a filter element isolation section 401 and a filter element inner cavity section 402. The filter element isolation section 401 is arranged corresponding to the isolation cavity 501 and has a filter element isolation section outer wall 4011. The filter element inner cavity section 402 is arranged corresponding to the inner cavity 503 and has a filter element inner cavity section outer wall 4021.

[0047] When the device is in the first backwash state, refer to Figure 7 and Figure 8 As shown, the control mechanism rotates 180° in the clockwise direction. At this time, the angle between the direction of the arrow 10 and the straight line where the extension direction of the housing 2 is located is 180°, that is, the handle 8 rotates the knob 9 from the closed state position by another 90°, the main channel 1101 connects the first water inlet 101 and the main water inlet 103, the opening direction of the secondary channel 1102 deviates from the opening direction of the secondary water inlet 102, that is, the main inlet is connected and the secondary inlet is closed. At this time, the first drain valve hole 1201 of the drain valve 12 that rotates synchronously with the knob 9 is connected to the first drain port 104, the second drain valve hole 1202 is connected to the third drain port 106, the water medium enters the inner cavity 503 from the main water inlet 103, and is separated into two paths after the impurities are removed by the filter element 4. Outflow, one way flows through the output flange 7 to the subsequent pipeline of the system, and the other way enters the isolation chamber 501 through the filter element 4 in the filter element isolation section 401. The water medium enters the outer chamber 502 through the through hole 301 from the isolation chamber 501, and passes through the third sewage outlet 106, the second sewage valve hole 1202 and the first sewage valve hole 1201 in sequence, and is discharged from the base 1 from the first sewage outlet 104. In this process, the water medium flows from the filter element 4 from the inside to the outside in the filter element isolation section 401, which can flush the filter element isolation section 401 and take away the dirt removed from the outer wall 4011 of the filter element isolation section when the device is normally used, and is discharged from the device through the above-mentioned channel. This process realizes a first-stage backwashing function, that is, the cleaning of the outer wall 4011 of the filter element isolation section.

[0048] When the device is in the second backwash state, refer to Fig. 9 and Fig.10As shown, the control mechanism rotates 270° in the clockwise direction. At this time, the pointing direction of the arrow 10 is perpendicular to the extension direction of the shell 2, that is, the handle 8 drives the knob 9 to rotate another 90° from the first backwash state. At this time, the main channel 1101 is perpendicular to the water channel of this device, that is, the main channel 1101 is perpendicular to the first water inlet 101, the main channel 1101 is connected to the secondary water inlet 102, the secondary channel 1102 is connected to the first water inlet 101, the first sewage valve hole 1201 of the sewage valve 12 that rotates synchronously with the knob 9 is connected to the first sewage outlet 104, and the second sewage valve hole 1202 is connected to the second sewage outlet 105, the water medium cannot enter the chamber from the main water inlet 103, the water medium enters the outer cavity 502 along the main channel 1101 through the secondary water inlet 102, and the water medium in the outer cavity 502 passes through the The hole 301 enters the isolation chamber 501, and after impurities are removed from the filter element isolation section 401, it enters the interior of the filter element 4. The water medium entering the filter element 4 flows out in two ways. One way flows out of the device from the output flange 7 and enters the subsequent pipeline of the system. The other way flows in the opposite direction along the interior of the filter element 4, flows to the filter element inner cavity section 402, and flows outward along the filter element inner cavity section 402 to the inner cavity 503, so as to flush the filter element inner cavity section 402 and take away the dirt removed from the outer wall 4021 of the filter element inner cavity section when the device is used. With the flushed dirt, the water medium is discharged from the base 1 from the first sewage outlet 104 through the second sewage outlet 105, the second sewage valve hole 1202 and the first sewage valve hole 1201 in sequence. This process realizes the second-speed backwashing function, that is, the cleaning of the outer wall 4021 of the filter element inner cavity section.

[0049] To ensure the sealing of the water inlet channel, a first seal 14 and a second seal 15 are respectively provided at both ends of the water inlet channel. To ensure the sealing of the sewage discharge channel, a third seal 16 and a fourth seal 17 are respectively provided at both ends of the sewage discharge channel.

[0050] The present embodiment provides a maintenance-free backwash water impurity removal device with multiple gears. By setting a handle 8, a knob 9 and a drain valve 12, a water supply ball valve 11 and a follower rod 13 that rotate synchronously with the knob 9, the handle 8 is turned to drive the knob 9 to move clockwise, so that the follower rod 13 rotates synchronously with the knob 9, so that the water inlet channel, the drain channel inside the base 1 and the multiple chambers in the shell 2 form different connection structures, and the arrows 10 on the knob 9 indicate different working states, which not only realizes the removal of impurities in the water medium, but also when the device is in the normal impurity removal state, the filter element isolation section 401 and the filter element inner cavity section 402 of the filter element 4 are involved in the impurity removal work, which increases the removal channel, improves the efficiency of impurity removal, and realizes the cleaning of the filter element 4. In addition, two backwash gears are provided, which can fully clean the filter element 4 as a whole, improve the cleaning efficiency, and extend the service life of the filter element 4.
