[0044] The method for using the organic wastewater pretreatment device according to any one of the above items comprises the following steps:

[0045] Step 1: Inject wastewater and flocculant into the sedimentation chamber through the liquid inlet pipe. Then the first servo motor drives the rotating rod to rotate, and the rotating rod drives the stirring blade to rotate to stir the wastewater. Then the valve is opened, allowing the wastewater to flow into the filter chamber through the valve. The liquid in the wastewater flows through the filter screen and flows out of the box through the corresponding discharge hole. The solid components in the wastewater remain on the top of the filter screen.

[0046] Step 2: The second servo motor drives the screw to rotate, and the screw rotation drives the slider to rise.

[0047] Step 3. When the slider rises, it drives the push rod to rise. The push rod squeezes the second spring upward, and the second spring squeezes the third rack upward. The movement of the third rack drives the second gear to rotate. At the same time, the movement of the third rack drives the limit block to move until the limit block moves to the inner wall of the third limit groove. At this time, the second gear rotates 180°, so that the first connecting hole faces downward and multiple exhaust holes face upward. During the rising process of the slider, the fourth inclined surface squeezes the piston block, so that the piston block squeezes the first spring and moves until the second connecting hole is connected to the air inlet groove. The external air supply equipment blows the gas to the bottom end of the filter through the air inlet groove, the first connecting hole, the connecting pipe and the exhaust hole in sequence, so that the solid components stuck in the filter holes of the filter can be blown away from the filter holes.

[0048] The present invention discloses an organic wastewater pretreatment device and a method for using the same, which have the following beneficial effects:

[0049] The present invention cooperates with the discharging mechanism and the cleaning mechanism, so that the solids can be directly cleaned on the separation mechanism after the wastewater is separated into solids and liquids by the separation mechanism, avoiding manual participation and increasing the convenience and efficiency of treatment. At the same time, under the action of the cleaning mechanism and through the cooperation of the blocking mechanism and the flipping mechanism, the cleaning mechanism cleans the filter screen by back-blowing the airflow while the discharging mechanism is working, thereby blowing out the solid particles stuck in the filter holes of the filter screen upward, thereby improving the convenience of cleaning the filter screen.

The outer wall of the limiting block 705 is slidably connected with the inner wall of the third limiting groove 704. When the slider 302 rises, the top rod 701 is driven to rise, the top rod 701 presses the second spring 702 upward, and the second spring 702 presses the third rack 507 upward, and the third rack 507 moves The second gear 505 can be driven to rotate, and the third rack 507 moves to drive the limit block 705 to move until the limit block 705 moves to the inner wall of the third limit groove 704. At this time, the second gear 505 rotates 180 degrees, so that the first connecting hole 602 faces downward and the multiple exhaust holes 502 face upward. During the rising process of the slider 302, the fourth inclined surface 608 squeezes the piston block 605, so that the piston block 605 squeezes the first spring 609 and moves until the second connecting hole 606 is connected to the air inlet groove 601. The external air supply equipment blows the gas to the bottom end of the filter screen 107 through the air inlet groove 601, the first connecting hole 602, the connecting pipe 501 and the exhaust hole 502 in sequence, so that the solid components stuck in the filter holes of the filter screen 107 can be blown away from the filter holes.The filter holes can be prevented from being clogged, thus ensuring that the separation mechanism can work stably. At the same time, by setting the flip mechanism, when the cleaning mechanism is not working, that is, after the wastewater passes through the separation mechanism, when the liquid component passes through the filter screen 107, since the exhaust hole 502 is set downward, the liquid will not flow into the inside of the connecting pipe 501, thus avoiding affecting the work of the cleaning mechanism. When the solid-liquid separation of the wastewater is completed, the mobile mechanism drives the discharge mechanism to work. At this time, the fourth inclined surface 608 squeezes the hemispherical surface 607, and the push rod 701 moves upward to squeeze, so that the external gas can pass through the air inlet groove 60 1 enters, and at the same time, the connecting pipe 501 also completes the flipping operation, without the need for manual control. The entire working process of the cleaning mechanism is synchronized with the operation of the discharging mechanism, thereby improving the convenience of the equipment operation. In addition, the setting of the second spring 702 in the flipping mechanism prevents the push rod 701 from controlling the stroke of the third rack 507. The stroke of the third rack 507 is controlled by the movement of the limit block 705 in the third limit groove 704, so that the maximum movement distance of the third rack 507 can just drive the second gear 505 to rotate 180 degrees, thereby improving the stability of the flipping mechanism.

[0070] A method for using an organic wastewater pretreatment device according to any one of the above items comprises the following steps:

[0071] Step 1: Wastewater and flocculant are injected into the sedimentation chamber 103 through the liquid inlet pipe 104. Then, the first servo motor 111 is driven to rotate the rotating rod 109. The rotating rod 109 rotates and drives the stirring blade 110 to stir the wastewater. Then, the valve 113 is opened, allowing the wastewater to flow into the filter chamber 105 through the valve 113. The liquid in the wastewater flows through the filter screen 107 and flows down through the corresponding discharge hole 200 to be discharged from the box 101. The solid components in the wastewater remain on the top of the filter screen 107.

[0072] Step 2: The second servo motor 316 drives the screw rod 313 to rotate. The screw rod 313 rotates and drives the slider 302 to rise. The slider 302 rises and drives the second slider 305 to rise through the connecting block 303. Then, the first rack 306 and the second rack 309 are respectively engaged with the first gear 308, which can drive the first slider 206 to tilt downward, thereby causing the movable baffle 202 to fall. The movable baffle 202 falls and drives the fixed rod 402 to fall. The fixed rod 402 falls and drives the roller 404 to fall, so that the roller 404 The roller 404 rolls along the third inclined surface 401 until it reaches the arc surface 405. At this time, the movable baffle 202 rotates counterclockwise around the end of the first slide bar 206 to be inclined. At this time, the scraper 112 rotates on the filter screen 107, so that the solid components on the filter screen 107 move to the communication groove 201 as the scraper 112 moves. The solid components fall onto the inclined movable baffle 202, then slide down through the gap between the movable baffle 202 and the inner wall of the box body 101, and finally discharge from the box body 101 through the corresponding discharge hole 200;

[0073] Step 3. When the slider 302 rises, the push rod 701 rises, and the push rod 701 presses the second spring 702 upward, and the second spring 702 presses the third rack 507 upward. The movement of the third rack 507 drives the second gear 505 to rotate. At the same time, the movement of the third rack 507 drives the limit block 705 to move until the limit block 705 moves to the inner wall of the third limit groove 704. At this time, the second gear 505 rotates 180 degrees, so that the first connecting hole 602 faces downward. , multiple exhaust holes 502 face upward, and during the rising process of the slider 302, the fourth inclined surface 608 squeezes the piston block 605, causing the piston block 605 to squeeze the first spring 609 and move until the second connecting hole 606 is connected to the air inlet groove 601. The external air supply equipment blows the gas to the bottom end of the filter 107 through the air inlet groove 601, the first connecting hole 602, the connecting pipe 501 and the exhaust hole 502 in sequence, so that the solid components stuck in the filter holes of the filter 107 can be blown away from the filter holes.
