DETAILED DESCRIPTION

[0029] 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.

[0030] Example 1

[0031] See also Figure 1 to Figure 7, a structural diagram of a construction wastewater treatment device provided in Example 1 of the present invention, the construction wastewater treatment device includes: a filter device 10, a support frame 20, a flocculation device 30 and a dosing box 40; the filter device 10 is installed on the support frame 20, the flocculation device 30 is arranged inside the support frame 20, and the output end of the filter device 10 is connected to the top of the flocculation device 30. A rotating shaft 301 is rotatably arranged inside the flocculation device 30, a mounting sleeve 302 is sleeved outside the rotating shaft 301, a plurality of stirring blades 303 are arranged in an array outside the mounting sleeve 302, and the mounting sleeve 302 is elastically slidably sleeved up and down on the rotating shaft 301; the flocculation device 30 is unidirectionally rotatably installed inside the support frame 20; two abutment rods 307 are symmetrically arranged outside the mounting sleeve 302, and two second one-way limiting members 308 are arranged inside the flocculation device 30, the second one-way limiting members 308 are symmetrically arranged outside the rotating shaft 301, and the second one-way limiting members 308 are arranged below the abutment rods 307, one side of the second one-way limiting member 308 is a vertical surface, and the other side is an inclined surface; a motor 312 for driving the rotating shaft 301 forward and reverse is also arranged on the support frame 20; a first sewage outlet 309 and a second sewage outlet 313 of different heights are arranged on the flocculation device 30. The flocculation device 30 is cylindrical.

[0032] The first sewage outlet 309 and the second sewage outlet 313 are both provided with a first switch valve to control the switch of the first and second sewage outlets.

[0033] When in use, the filter device 10 filters the wastewater, and the wastewater after filtration flows into the flocculation device 30. When the wastewater inside the flocculation device 30 is added to the set amount, the filter device 10 stops filtering, and the dosing box 40 adds flocculant into the flocculation device 30. After the flocculant is added, the motor 312 drives the shaft 301 to rotate, and the shaft 301 drives the mounting sleeve 302 to rotate. The stirring blade 303 on the mounting sleeve 302 stirs the wastewater inside the flocculation device 30. When the resistance rod 307 rotates with the mounting sleeve 302, the resistance rod 307 resists the inclined surface of the second one-way limiter 308, so that the resistance rod 307 drives The installation sleeve 302 and the stirring blade 303 jump up and down to achieve jumping stirring, so that the wastewater and the flocculant can be evenly mixed. After the mixing is completed, the motor 312 stops driving the rotating shaft 301 to rotate. After standing for a period of time, the motor 312 drives the rotating shaft 301 to rotate in the opposite direction. At this time, the resistance rod 307 resists the vertical surface of the second one-way limiter 308. At this time, the resistance rod 307 drives the flocculation device 30 to rotate through the second one-way limiter 308, and the flocculation device 30 is quickly precipitated under the action of centrifugal force. After the separation is completed, the second sewage outlet 313 at a high position is first opened to discharge the sewage, and then the first sewage outlet 309 at a low position is opened to discharge the sediment. The present invention is provided with stirring blades 303, the rotating shaft 301 and the installation sleeve 302, so that the flocculant can be quickly and evenly mixed with the sewage, and after the mixing is completed, the motor 312 drives the flocculation device 30 to rotate through the second one-way limiter 308 and the resistance rod 307. Under the action of centrifugal force, the flocculants are quickly precipitated and the sewage treatment efficiency is improved.

[0034] like Figure 2 As shown, in some embodiments, two second sliders 311 are symmetrically installed on the outer side of the rotating shaft 301, and the second sliders 311 are slidably arranged in the second slide grooves 310 on the mounting sleeve 302 up and down. There are two second slide grooves 310, and each second slider 311 is slidably arranged in the adjacent second slide grooves 310. The second slide grooves 310 are strip-shaped structures.

[0035] In some embodiments, a second elastic member 304 is disposed between the rotating shaft 301 and the mounting sleeve 302, and two ends of the second elastic member 304 are respectively mounted on the rotating shaft 301 and the mounting sleeve 302, such as elastically mounting the mounting sleeve 302 on the rotating shaft 301. The second elastic member 304 may be a coil spring. The second elastic member 304 may be disposed on the top of the rotating shaft 301.

[0036] In some embodiments, the motor 312 and the rotating shaft 301 may be connected via gears or belts.

[0037] In order to make the flocculation device 30 be installed on the support frame 20 in one direction, a limiting mechanism for limiting the unidirectional rotation of the flocculation device 30 is also arranged between the flocculation device 30 and the support frame 20. The limiting mechanism includes an elastic telescopic rod 306 arrayed on the outside of the flocculation device 30 and a first unidirectional limiting member 305 arrayed on the support frame 20. One side of the first unidirectional limiting member 305 is a limiting side and the other side is a guiding side. The limiting side can be a vertical plane structure, and the guiding side is inclined relative to the vertical plane. In this way, when the elastic telescopic rod 306 hits the limiting side, it cannot slide over. When the elastic telescopic rod 306 hits the guiding side, it can automatically expand and contract under the action of elasticity, so that it can slide over the elastic telescopic rod 306. In this way, the unidirectional rotation of the flocculation device 30 is achieved. In this way, when the flocculation device 30 rotates with the rotating shaft 301, the elastic telescopic rod 306 can slide over the first unidirectional limiting member 305.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, as some embodiments of the present invention, the filter device 10 includes a filter channel 101, a filter screen 103 is rotatably arranged inside the filter channel 101, a slag storage chamber 102 is also arranged on the side wall of the filter channel 101, the slag storage chamber 102 is arranged directly above the filter screen 103, and the slag storage chamber 102 is arranged on the periphery of the filter screen 103; a slag discharge port 104 is also arranged on the slag storage chamber 102, and a second switch valve is arranged on the slag discharge port 104.

[0039] In some embodiments of the present invention, an intermediate disk 105 is installed directly below the filter screen 103, a hydraulic component is arranged directly below the intermediate disk 105, the hydraulic component is rotatably installed in the filter channel 101, and an energy storage component is arranged between the hydraulic component and the intermediate disk 105. During the filtering process, when the sewage passes through the hydraulic component, the hydraulic component is driven to rotate, and the rotation of the hydraulic component stores energy in the energy storage component. When the filtering is completed, the hydraulic component stops rotating, and the energy storage component releases energy, so that the filter screen 103 rotates, and the impurities on the filter screen 103 are caused to enter the residue storage chamber 102 under the action of centrifugal force, thereby realizing the self-cleaning of the filter screen 103.

[0040] In some embodiments of the present invention, the filter screen 103 is circular in shape, and the middle portion thereof is convex upward.

[0041] In some embodiments of the present invention, the hydraulic component includes a center ring 123 and a plurality of spiral blades 124 arranged in an array outside the center ring 123. The center ring 123 is rotatably sleeved on the intermediate shaft 107, and the intermediate shaft 107 is fixedly installed at the center of the filter channel 101. In this way, when the wastewater passes through the spiral blades 124, the center ring 123 can be driven to rotate. The center ring 123 is elastically rotatably installed on the intermediate shaft 107 up and down.

[0042] like Figure 2 , Figure 3 and Figure 4As shown in some embodiments of the present invention, the energy storage assembly includes a matching ring 106, a first energy storage member 111, a first energy storage ring 114 and a transmission assembly; the matching ring 106 is slidably arranged below the middle disk 105, and the matching ring 106 is concentrically arranged with the middle disk 105; the two ends of the first energy storage member 111 are respectively fixedly installed on the matching ring 106 and the first energy storage ring 114, the first energy storage ring 114 is unidirectionally rotatably installed on the first mounting ring 113, and the first mounting ring 113 is slidably arranged in the filter channel 101; two The first slider 110, the two first sliders 110 are both slidably set in the first slide groove 108 of the intermediate shaft 107, and two guide partitions 109 are arranged in an array on the first slide groove 108. The top of the guide partition 109 is lower than the upper edge of the first slide groove 108, and the middle position of the top of the guide partition 109 is higher than the positions on both sides. The transmission component is set between the center ring 123 and the first energy storage ring 114. In this way, when the first slider 110 touches the top of the guide partition 109, it can move downward along the guide partition 109 under the guiding action of the top structure of the guide partition 109. During the wastewater filtration process, under the impact of the water flow, the spiral blades 124 and the first elastic member 125 move downward, and at the same time, the first elastic member 125 drives the first energy storage ring 114 and the first mounting ring 113 to move downward, and the first energy storage ring 114 drives the matching ring 106 to move downward through the first energy storage member 111, so that the first slider 110 on the matching ring 106 is transferred to the position between the two guide partitions 109 due to the position above the guide partition 109, thereby limiting the rotation of the matching ring 106. At this time, under the impact of the water flow, the spiral blades 124 drive the center ring 123 to rotate, and the rotation of the center ring 123 drives the first energy storage ring 114 to rotate through the rotating assembly, and the first energy storage ring 114 stores energy for the first energy storage member 111. When the filtration is stopped, under the action of elasticity, the center ring 123 returns to the initial position, thereby causing the first energy storage ring 114 and the matching ring 106 to return to the initial position, and at the same time, the first slider 110 moves upward. When the first slider 110 is higher than the guide partition 109, the guide partition 109 releases the rotation restriction of the first slider 110. At this time, the first energy storage ring 114 can return to the initial state, release energy, and then drive the matching ring 106, the intermediate disk 105 and the filter screen 103 to rotate. In this way, impurities on the surface of the filter screen 103 enter the slag discharge port 104 under the action of centrifugal force. The first energy storage ring 114 is unidirectionally rotatably mounted on the first mounting ring 113, so that during the energy storage process, the first energy storage ring 114 will have a tendency to rotate in the opposite direction under the action of the second energy storage member 112, and under the action of the first mounting ring 113, it is further restricted from rotating in the opposite direction to ensure that the energy is used by the filter screen 103. The first mounting ring 113 can also be set inside the filter channel 101 by sliding up and down on a linear slide rail. The first energy storage member 111 and the second energy storage member 112 may both be torsion springs.

[0043] A one-way ratchet structure is provided between the first mounting ring 113 and the first energy storage ring 114 , which is a prior art and will not be described in detail herein.

[0044] The first sliding block 110 is gradually contracted toward the center from top to bottom, so that both sides of the first sliding block 110 are inclined surfaces, so that the first sliding block 110 can slide to the bottom of the first sliding groove 108 .

[0045] like Figure 7 In some other embodiments, the top of the guide partition 109 is a slope structure, that is, the top of the guide partition 109 is gradually arranged away from the inner wall of the first slide groove 108 from top to bottom, and the first slider 110 is a telescopic rod, so that when the first slider 110 moves downward, it can pass through the top of the guide partition 109, so that the first slider 110 and the mating ring 106 can move downward.

[0046] In some embodiments of the present invention, in order to improve energy storage, the energy storage assembly further includes a first energy storage member 111, a second energy storage ring 115 and a second mounting ring 116. The upper end of the first energy storage member 111 is fixedly mounted on the matching ring 106, the lower end of the first energy storage member 111 is fixedly mounted on the second energy storage ring 115, the second energy storage ring 115 is unidirectionally mounted on the second mounting ring 116, and the second mounting ring 116 is slidably sleeved on the intermediate shaft 107. The first energy storage ring 114 has the same rotation direction as the second energy storage ring 115.

[0047] The second energy storage ring 115 is rotatably sleeved on the inner side of the first energy storage ring 114 .

[0048] As some embodiments of the present invention, the second mounting ring 116 can be slid up and down on the intermediate shaft 107 by a linear slide rail.

[0049] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the present invention, the transmission assembly includes a rotating shaft 119 unidirectionally mounted on a center ring 123, two first drive plates 120 are arranged in an array at one end of the rotating shaft 119, and two second drive plates 121 are arranged in an array at the other end of the rotating shaft 119, the first drive plates 120 are symmetrically arranged on the rotating shaft 119, and the second drive plates 121 are symmetrically arranged on the rotating shaft 119, and the installation angles of the first drive plates 120 and the second drive plates 121 differ by 90°; two first protruding blocks 117 are symmetrically arranged at the bottom of the first energy storage ring 114, and two second protruding blocks 118 are symmetrically arranged at the bottom of the second energy storage ring 115. In the initial state, one of the first drive plates 120 abuts against one of the first protruding blocks 117, so that the center ring 123 rotates, and drives the first energy storage ring 114 to rotate through the first drive plate 120 and the first protruding block 117. When the second energy storage member 112 on the first energy storage ring 114 completes energy storage, the first energy storage ring 114 cannot rotate. At this time, the rotating shaft 119 deflects, so that the first protruding block 117 is out of contact with the first drive plate 120, and one of the second drive plates 121 at the other end is transferred to the track of the second protruding block 118. In this way, when the second protruding block 118 contacts the second drive plate 121, the center ring 123 drives the second protruding block 118 to drive the second energy storage ring 115 to rotate through the second drive plate 121, and the second energy storage ring 115 drives the first energy storage member 111 to rotate, so that the first energy storage member 111 is in an energy storage state. When the filtration is stopped, the matching ring 106 releases the display, and the first energy storage member 111 and the second energy storage member 112 simultaneously drive the matching ring 106 to rotate, increasing the energy storage. The rotating shaft 119 is rotatably disposed along the radial direction of the center ring 123. The first protruding block 117 is disposed along the radial direction of the first energy storage ring 114, and the second protruding block 118 is disposed along the radial direction of the second energy storage ring 115.

[0050] like Figure 2-Figure 6 As shown, in some embodiments of the present invention, an intermediate disk 122 is sleeved on the middle position of the rotating shaft 119, and four matching grooves 127 are arranged on the intermediate disk 122. A driving rod 126 is also provided on the center ring 123. The driving rod 126 is elastically rotatably mounted on the center ring 123, and the top of the driving rod 126 is set in one of the matching grooves 127. When the second energy storage ring 115 or the first energy storage ring 114 cannot rotate, the driving rod 126 is subjected to a relatively large resistance, so that the driving rod 126 deflects, and the rotation restriction of the intermediate disk 122 is released, so that the rotating shaft 119 rotates, and the rotating shaft 119 rotates less than 90°. When the second protruding block 118 at the bottom of the second energy storage ring 115 contacts the second driving plate 121 or the first protruding block 117 contacts the first driving plate 120, the rotating shaft 119 continues to rotate, so that the rotating shaft 119 rotates a full 90°, and the driving rod 126 enters the next matching groove 127 at this time, and the rotating shaft 119 is limited again.

[0051] In some embodiments of the present invention, the driving rod 126 is rotatably installed in the center ring 123 via a pin shaft, a torsion spring is sleeved on the outer side of the pin shaft, and both ends of the torsion spring are fixedly installed on the driving rod 126 and the center ring 123 respectively.

[0052] In some embodiments of the present invention, a third switch valve is provided at the output end of the medicine adding box 40, and the third switch valve may be a solenoid valve.

[0053] The working principle of the present invention is:

[0054] The filter screen 103 in the filter device 10 filters the wastewater. During the filtering process, the hydraulic components are driven to rotate, thereby causing the energy storage component to store energy. After the filtering is completed, the energy storage component releases energy to the residue storage chamber 102, and the residue storage chamber 102 rotates to remove impurities on its surface. The filtered wastewater flows into the flocculation device 30. When the wastewater inside the flocculation device 30 is added to the set amount, the filter device 10 stops filtering, and the dosing box 40 adds flocculant to the flocculation device 30. After the flocculant is added, the motor 312 drives the shaft 301 to rotate, and the shaft 301 drives the installation sleeve 302 to rotate. The stirring blade 303 on the installation sleeve 302 stirs the wastewater inside the flocculation device 30. As the resistance rod 307 rotates with the installation sleeve 302 , the resistance rod 307 resists the inclined surface of the second one-way limiter 308, so that the resistance rod 307 drives the installation sleeve 302 and the stirring blade 303 to jump up and down, realizing jumping stirring, and the wastewater and flocculant can be evenly mixed. After the mixing is completed, the motor 312 stops driving the rotating shaft 301 to rotate. After standing for a period of time, the motor 312 drives the rotating shaft 301 to rotate in the opposite direction. At this time, the resistance rod 307 resists the vertical surface of the second one-way limiter 308. At this time, the resistance rod 307 drives the flocculation device 30 to rotate through the second one-way limiter 308, and quickly precipitates under the action of centrifugal force. After separation is completed, the second sewage outlet 313 at a high position is first opened to discharge the sewage, and then the first sewage outlet 309 at a low position is opened to discharge the sediment.
