Description

Technical Field

[0001] The invention relates to the field of water resource purification, and in particular to a self-cleaning and low-emission water purification device. Background Art

[0002] Water purification equipment is a device used to remove impurities, pollutants and harmful substances in water to provide clean and safe drinking water. With the continuous improvement of science and technology, there are more and more water purification methods to choose from. Using ceramic filters to purify water is one of them. Ceramic filters use microporous ceramic filter elements to filter particles and bacteria in the water, while retaining minerals and trace elements in the water to provide healthy drinking water. However, as the use time of ceramic filters continues to increase, in order to avoid affecting the water purification effect, it is necessary to clean the ceramic filters. The existing technology generally uses an automatically running brush or high-pressure water to clean the water. There are three problems with backwashing the water flow for cleaning: first, the surface of the ceramic filter element is relatively fragile, and the use of cleaning tools such as brushes for automatic cleaning can easily damage the micropores on its surface; second, the equipment itself is in the water, and the impact effect of the high-pressure water flow will be affected, and the still water will weaken the high-pressure water flow; third, the water flow will carry mud and impurities. During the water purification process, because the water flow is stationary, silt will accumulate. When the silt accumulates to a certain extent, it will affect the overall water purification effect. During the cleaning process, the operator is prone to cause a large amount of silt to surge due to operational problems, causing the water flow to be polluted again.

[0003] Therefore, a self-cleaning, low-emission water purification device is now developed to address the above problems. Summary of the invention

The suction generated by the negative pressure device will cause the impurities on the cleaning roller to enter the connecting pipe through the negative pressure guide and be discharged eventually, thereby achieving the effect of quickly cleaning the cleaning roller.

[0016] 4. When the sliding frame moves to the left, the rotating plate will be pushed by the pressure of the silt and flip to the right. At this time, the torsion spring will be deformed by the force. When the silt enters the sliding frame, the rotating plate will no longer be pushed. Under the action of the torsion spring, the rotating plate will flip to the left and reset, thereby blocking the silt and preventing it from gushing out, thus preventing a large amount of silt from surging.

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1 A self-cleaning, low-emission water purification device, such as Figure 1 and Figure 2As shown, it includes a water purification frame 1, a ceramic membrane water purification component 2 for purifying water flow is placed inside the water purification frame 1, a water outlet pipe 3 for guiding the purified water flow to precipitate is connected to the top of the ceramic membrane water purification component 2, a backwash component 4 for backwashing and cleaning the ceramic membrane water purification component 2 is installed on the right side of the water purification frame 1, the backwash component 4 is composed of a water supply pump and a connecting pipe 83, the front and rear parts of the water purification frame 1 are both equipped with water inlets 5, and also include: a self-cleaning mechanism 6, the self-cleaning mechanism 6 is arranged on the ceramic membrane water purification component 2, and the self-cleaning mechanism 6 is used to automatically clean the ceramic membrane water purification component 2; a silt removal mechanism 7, the silt removal mechanism 7 is arranged in the lower part of the water purification frame 1, and the silt removal mechanism 7 is used to push and clean the silt deposited in the lower part of the water purification frame 1.

[0031] It should be noted that the water purification equipment is a device used to remove impurities, pollutants and harmful substances in water and provide clean and safe drinking water. When purifying water, this device can be used to perform processing operations. First, the water flow is introduced into the water purification frame 1 through the water inlet 5 so that the water flow can enter the ceramic membrane water purification component 2. The ceramic membrane water purification component 2 uses a microporous ceramic filter element to filter particles and bacteria in the water while retaining minerals and trace elements in the water. Then, the pumping equipment is connected to the outlet pipe 3. After the water flow purification is completed, the pumping equipment is started, so that the purified water flow is precipitated through the outlet pipe 3 and the discharge is conducted. After the water purification is completed, the self-cleaning mechanism 6 and the silt removal mechanism 7 can be started. The filter element of the ceramic membrane water purification component 2 is cleaned by the self-cleaning mechanism 6 to avoid wear on the filter element during the cleaning process. At the same time, the silt removal mechanism 7 will scrape and clean the silt deposited at the bottom of the water purification frame 1 to avoid excessive silt deposition at the bottom of the water purification frame 1, which affects the water purification effect.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the self-cleaning mechanism 6 includes a driving motor 61, and the driving motor 61 is installed on the upper right front side and the upper left rear side of the ceramic membrane water purification component 2. The output shaft of the driving motor 61 is set downward, and the output shaft of the driving motor 61 is connected to a screw rod 63. The bottom of the screw rod 63 is rotatably connected to the ceramic membrane water purification component 2. The right rear and left front of the ceramic membrane water purification component 2 are connected to a first guide rod 64. A mounting bracket 62 is slidably arranged between the first guide rods 64. The mounting bracket 62 is threadedly connected to the screw rod 63. The front and rear parts of the mounting bracket 62 Six groups of sliding members 65 are slidably arranged, and each two sliding members 65 close to each other form a group. Springs 66 are connected between the sliding members 65 and the mounting frame 62. Cleaning rollers 67 for cleaning the filter elements in the ceramic membrane water purification assembly 2 are rotatably arranged between the front and rear symmetrical sliding members 65. There are twelve cleaning rollers 67 in total, and each cleaning roller 67 has a soft cleaning bump. Gears 68 are connected to the left and right ends of the cleaning rollers 67, and rack racks 69 corresponding to the number of gears 68 are connected to the left and right parts of the ceramic membrane water purification assembly 2.

[0033] It should be noted that by starting the driving motor 61, the self-cleaning mechanism 6 starts to operate automatically. The rotation of the output shaft of the driving motor 61 will drive the screw rod 63 to rotate. During the rotation, the screw rod 63 will drive the mounting frame 62 to slide downward along the first guide rod 64. As the mounting frame 62 starts to slide downward, the sliding member 65 will also move downward synchronously, thereby driving the cleaning roller 67 to move downward. During the downward movement of the cleaning roller 67, the gear 68 will rotate under the action of the corresponding rack rack 69. The two cleaning rollers 67 close to each other rotate in opposite directions. The opposite rotation of the cleaning rollers 67 drives the soft cleaning protrusions to contact the filter elements of the ceramic membrane water purification assembly 2, thereby achieving a flexible cleaning effect and avoiding damage to the filter elements of the ceramic membrane water purification assembly 2. It should be particularly noted that, under the action of the spring 66, the sliding member 65 will keep the cleaning roller 67 in contact with the filter element of the ceramic membrane water purification assembly 2 at all times, thereby avoiding the presence of a gap between the cleaning roller 67 and the filter element of the ceramic membrane water purification assembly 2, which would affect the cleaning effect. In summary, the driving motor 61 provides power so that the mounting frame 62 can move automatically. During the automatic movement of the mounting frame 62, the cleaning roller 67 can rotate automatically by relying on the cooperation of the gear 68 and the rack frame 69, so that the soft cleaning protrusions can scrape and clean the filter element of the ceramic membrane water purification assembly 2, thereby avoiding the attachment of impurities to the filter element of the ceramic membrane water purification assembly 2, which would affect the water purification effect. In addition, the soft cleaning protrusions can also avoid damage to the filter element of the ceramic membrane water purification assembly 2 during the cleaning process.

[0034] like Figure 1 , Figure 7 and Fig.10As shown, the silt removal mechanism 7 includes a second guide rod 71, and the second guide rods 71 ​​are connected to the front and rear sides of the lower part of the water purification frame 1. A sliding frame 72 is slidably arranged between the second guide rods 71. The sliding frame 72 is an L-shaped structure. Two storage bins are connected to the right side of the sliding frame 72, which can collect silt to a certain extent. A fixed frame 73 for positioning and blocking the sliding frame 72 is connected to the left side of the ceramic membrane water purification component 2. Two silt suction pipes 74 are connected to the left side of the fixed frame 73. The silt suction pipes 74 are connected to the fixed frame 7 3 is connected and communicated, the sludge suction pipe 74 is connected to the left part of the water purification frame 1 in a through-type manner, winding components 76 are connected to the left and right side walls of the upper inner part of the water purification frame 1, and the winding components 76 are connected to the pull rope 77, the winding components 76 include a winding motor and a winding shaft, the pull rope 77 is connected to the sliding frame 72, and the left and right side walls of the lower inner part of the water purification frame 1 are connected to the guide components 75 for guiding and limiting the pull rope 77, the guide components 75 include a mounting part and a wire wheel, and the pull rope 77 is wound on the adjacent wire wheels.

[0035] It should be noted that in order to prevent sludge accumulation during the long-term water purification process, the operator needs to regularly process the sludge at the bottom of the water purification frame 1. First, according to the position of the sliding frame 72, the winding assembly 76 on the left is started. As the winding assembly 76 on the left is started, the pull rope 77 on the left will be pulled, so that the sliding frame 72 is pulled to the left. During the movement of the sliding frame 72 to the left, the sludge deposited at the bottom of the water purification frame 1 will be pushed. At the same time, since the sliding frame 72 is an L-shaped structure, it can gather the sludge to a certain extent and push the sludge to the left, so that the sludge can be slowly gathered. On the right side of the fixed frame 73, the extraction device is then connected to the silt suction pipe 74, and then the extraction device is started, so that the silt that slowly accumulates is extracted through the silt suction pipe 74 to complete the cleaning of the silt. After the treatment is completed, the winding assembly 76 on the left is closed, and the winding assembly 76 on the right is started at the same time. At this time, the winding assembly 76 on the right will pull the pull rope 77 on the right, so that the sliding frame 72 starts to slide to the right and reset to its original position. In the process of the pull rope 77 being pulled, the guide assembly 75 will guide the adjacent pull ropes 77 to avoid the pull rope 77 from being offset due to the water flow power.

[0036] Example 2 On the basis of Example 1, Figure 1 , Figure 8 and Fig. 9 As shown, a negative pressure mechanism 8 is also included, and the negative pressure mechanism 8 includes a fixed plate 81. The upper sides of the front and rear parts of the ceramic membrane water purification assembly 2 are connected to the fixed plates 81. Twelve connecting pipes 83 are slidably connected to the fixed plates 81. Twelve negative pressure guide members 82 are connected to the mounting frame 62. The negative pressure guide members 82 are connected and communicated with adjacent connecting pipes 83.

[0037] It should be noted that when the cleaning roller 67 is cleaning the filter element of the ceramic membrane water purification assembly 2, a large amount of impurities will also adhere to the surface of the cleaning roller 67. In order to prevent the impurities from affecting the cleaning effect of the cleaning roller 67, the operator can connect the negative pressure device to the connecting pipe 83. During the movement of the cleaning roller 67, the negative pressure device is started synchronously. The suction force generated by the negative pressure device will cause the impurities on the cleaning roller 67 to enter the connecting pipe 83 through the negative pressure guide 82 and finally be discharged, thereby achieving the effect of quickly cleaning the cleaning roller 67.

[0038] like Figure 7 and Fig.10 As shown, it also includes a surge prevention mechanism 9, which includes a fixing member 91. The fixing member 91 is connected to the left side of the sliding frame 72. A rotating plate 92 is rotatably arranged on the fixing member 91. The rotating plate 92 is an inclined structure as a whole. Two torsion springs 93 are connected between the rotating plate 92 and the fixing member 91.

[0039] It should be noted that when the sliding frame 72 moves to the left, the rotating plate 92 will be pushed by the pressure of the silt and thus flip to the right. At this time, the torsion spring 93 will be deformed by the force. When the silt enters the sliding frame 72, the rotating plate 92 is no longer pushed. Under the action of the torsion spring 93, the rotating plate 92 will flip to the left and reset, thereby blocking the silt and preventing the silt from gushing out, thereby preventing a large amount of silt from surging.

[0040] like Figure 7 and Fig.10 As shown, it also includes a gathering component 10, which includes a first gathering piece 101. The first gathering pieces 101 are connected to the left sides of the front and rear parts of the sliding frame 72, and the first gathering pieces 101 are all inclined structures inclined inwardly. A second gathering piece 102 is connected to the left side of the middle part of the sliding frame 72, and the front and rear sides of the second gathering piece 102 are both inclined structures. The rear side inclined surface of the second gathering piece 102 corresponds to the first gathering piece 101 on the rear side, and the front side inclined surface of the second gathering piece 102 corresponds to the first gathering piece 101 on the front side, which is used to gather the sludge to the middle position when pushing the sludge.

[0041] like Figure 1 and Fig.11 As shown, a buffer mechanism 11 is also included, and the buffer mechanism 11 includes a buffer ramp 111. Two front-to-back symmetrical buffer ramps 111 are connected to the left side wall of the water purification frame 1. The buffer ramps 111 are located below the corresponding water inlet 5. Multiple spoilers 112 are connected to the buffer ramps 111. The buffer ramps 111 and the spoilers 112 cooperate to slow down the water flow entering the water purification frame 1 to prevent the water flow from being too fast and washing up the bottom silt.
