When the rotating shaft 151 drives the rotating rod 152 to rotate, a vortex can be formed in the inclined tube 200, the cleaning mode can improve the impact of water flow on the inner wall of the inclined tube 200, impurities mixed into the water flow can flow away from the inclined tube 200 quickly, the possibility that the impurities are adhered to the inner wall of the inclined tube 200 again is reduced, the cleaning effect on the inclined tube 200 is improved, and the fluxion and the service life of the inclined tube 200 are obviously improved.
After cleaning, the rotary driving piece does not drive the rotating shaft 151 to rotate any more, the rotating rod 152 is suspended at the bottom of the rotating shaft 151 under the action of gravity, the lifting driving piece 130 drives the bracket 120 to move upwards so that the rotating piece 150 leaves the water body, and the rotating rod 152 is not easy to carry up the stirred solid impurities in the water body due to the suspension state. The conventional sedimentation treatment can be continued after the rotating member 150 leaves the water body, and the rotating member 150 and the bracket 120 do not interfere with the normal progress of the sedimentation treatment.
Referring to fig. 6, in an alternative embodiment, the rotary 150 further includes: the cleaning liquid is injected into the shaft 153. The cleaning liquid injection shaft 153 is provided with a liquid injection channel 153a through which the cleaning liquid flows, that is, the cleaning liquid injection shaft 153 is a hollow shaft. In view of the acidity of the waste water in the sulfuric acid production, a cleaning liquid such as an alkaline solution may be injected into the liquid injection passage 153a, so that the neutralization reaction is performed by injecting the cleaning liquid into the inclined tube 200 later, and the cleaning liquid may be a flocculant or the like. The rotating shaft 151 is a hollow shaft, and the cleaning solution injection shaft 153 is coaxially arranged with the rotating shaft 151 and is positioned at the inner side of the rotating shaft 151; the bottom end of the liquid injection channel 153a penetrates the cleaning liquid injection shaft 153, i.e., the cleaning liquid in the liquid injection channel 153a can be sprayed out from the bottom end of the cleaning liquid injection shaft 153.
Thus, the cleaning liquid can be injected into the inclined tube 200 through the liquid injection passage 153a, thereby further improving the cleaning effect. The direct injection of the cleaning liquid into the inside of each inclined tube 200 instead of the entire injection of the cleaning liquid into the accommodating chamber 110a can also enhance the cleaning effect and reduce the consumption of the cleaning liquid.
Referring to fig. 7, in an alternative embodiment, the cleaning solution injection shaft 153 is connected to the rotating shaft 151 in a rotation-stopping manner, for example, a protrusion may be disposed on a side wall of the rotating shaft 151 in which the cleaning solution injection shaft 153 is sleeved, a groove into which the protrusion is inserted is disposed on an inner wall of the rotating shaft 151, and the relative rotation of the cleaning solution injection shaft 153 and the rotating shaft 151 is limited by the cooperation of the protrusion and the groove, which is not shown in the drawings. Of course, those skilled in the art may set the specific form of the rotation-stopping connection of the cleaning solution injection shaft 153 to the rotation shaft 151 according to actual needs, which is not limited herein. The rotary 150 further includes: a tip 154. Wherein, the tip 154 is fixedly disposed at the bottom end of the cleaning liquid injection shaft 153. The tip 154 is provided with a plurality of perforations 154a communicating with the pouring channel 153 a. The axial direction of the through hole 154a is disposed obliquely to the axial direction of the rotation shaft 151.
By adopting the technical scheme, the cleaning solution is sprayed out from the through holes 154a and is inclined to the rotating shaft 151, so that the cleaning solution is favorable to be close to the inner wall of the inclined tube 200, and the concentration of the cleaning solution in the part, close to the inner wall of the inclined tube 200, of the inclined tube 200 is higher than that of the cleaning solution in the central part, thereby fully utilizing the cleaning solution and improving the use effect of the cleaning solution.
In an alternative embodiment, the cleaning fluid injection shaft 153 is inserted into the lumen 121 at its top end. The cleaning solution injection shaft 153 is slidably connected to the rotating shaft 151 in the up-down direction, for example, on the basis of the above-mentioned engagement between the protrusions and the grooves, the length of the grooves extending in the axial direction of the rotating shaft 151 is longer than the length of the protrusions in the axial direction of the cleaning solution injection shaft 153, so that the protrusions can slide in the grooves. Meanwhile, defining the rotation member 150 further includes: a guide ring 155 and a spring 156. Wherein, the guide ring 155 is coaxially and fixedly arranged at the part of the cleaning liquid injection shaft 153 located in the inner cavity 121. The elastic member 156 is disposed between the bracket 120 and the guide ring 155 to bias the guide ring 155 to have a tendency to slide with respect to the rotation shaft 151. The bottom of the guide ring 155 is provided with a guide curved surface 155a. Contacts 122 are disposed within the interior 121 of the holder 120. The contact 122 contacts the guide curved surface 155a to restrict the guide ring 155 from sliding with respect to the rotation shaft 151.
Referring to fig. 6, the guide curved surface 155a may be a complete ring surface with one side high and the other side low, or may be formed by splicing a plurality of uneven surfaces, so that when the guide curved surface 155a contacts the contact 122, the contact 122 provides support to the guide ring 155, and the elastic member 156 applies pressure to the guide ring 155. When the guide ring 155 rotates along with the cleaning solution injection shaft 153, the elastic member 156 and the contact member 122 drive the guide ring 155 to move up and down, so that the cleaning solution injection shaft 153 moves up and down relative to the rotating shaft 151.
Through adopting above-mentioned technical scheme, the rotation of guide ring 155 relative contact 122 can drive washing liquid injection shaft 153 relative pivot 151 to slide from top to bottom, and then at the in-process of washing liquid at injection chute 200, washing liquid injection shaft 153's upper and lower slip can promote rivers and relapse the impact chute 200 inner wall from top to bottom for rotating member 150 promotes the disturbance effect of rivers in chute 200, further makes the impurity on the inner wall of chute 200 lower position can be cleared up by rivers and the washing liquid in the rivers, further promotes the cleaning effect.
Further, it is contemplated that the shaft 151 may be rotated at a relatively high rotational speed (e.g., greater than 120 r/min) in order to form a vortex within the chute 200. At this time, if the cleaning liquid injection shaft 153 moves up and down too frequently, the vortex formed in the water body in the inclined tube 200 is easily broken. Therefore, it is preferable that the guide curved surface 155a is a complete annular surface with one side being high and the other side being low in the present application to limit the frequency of the up-and-down movement of the cleaning liquid injection shaft 153.
Alternatively, the contact 122 may be a sphere, and the sphere is rotatably disposed in the cavity 121 of the bracket 120 to reduce wear between the contact 122 and the guide surface.
Referring to fig. 8, in an alternative embodiment, a cleaning solution adapter ring 123 is fixedly provided at the bottom of the bracket 120. The cleaning solution transferring ring 123 is sleeved outside the rotating shaft 151, that is, the cleaning solution transferring ring 123 can rotate relative to the rotating shaft 151. The cleaning solution adapter ring 123 is provided with an intermediate chamber 123a, and the intermediate chamber 123a can be used for filling the cleaning solution to be injected into the liquid inlet channel. The rotary 150 further includes: collar 157 and several transition tubes 158. Wherein, a plurality of transfer tubes 158 are connected between the middle chamber 123a and the filling channel 153 a. Collar 157 is fixedly disposed at one end of several transfer tubes 158 near middle chamber 123a and inserted into middle chamber 123a, and the connection between collar 157 and transfer tubes 158 may be, for example, welding. The rotating shaft 151 is circumferentially provided with sliding grooves 151a corresponding to the adapter tubes 158 one by one. One end of the transfer tube 158, which is close to the cleaning liquid injection shaft 153, passes through the slide groove 151a and is fixedly connected with the cleaning liquid injection shaft 153. Collar 157 is sleeved outside of shaft 151. That is, when the cleaning liquid injection shaft 153 moves up and down with respect to the rotation shaft 151, the switching tube 158 moves in synchronization with the collar 157, wherein the collar 157 moves up and down in the intermediate chamber 123 a.
By adopting the above technical scheme, in the process of moving the cleaning solution injection shaft 153 up and down, the collar 157 also moves up and down relative to the cleaning solution transfer ring 123, so that the cleaning solution in the middle chamber 123a can be extruded to be sprayed into the inclined tube 200 with higher hydraulic pressure and flow rate, so that the cleaning solution can be quickly near the inner wall of the inclined tube 200 after being sprayed into the inclined tube 200, and the concentration of the cleaning solution in the inclined tube 200 near the inner wall is further improved, thereby improving the cleaning effect.
It is understood that sealing treatment is performed between the inner wall of the intermediate chamber 123a and the collar 157, between the collar 157 and the rotation shaft 151, and between the cleaning liquid transferring ring 123 and the rotation shaft 151, for example, a sealing ring is provided at each contact position to form a contact seal, etc., so as to avoid leakage of the cleaning liquid.
In an alternative embodiment, the bracket 120 is fixedly provided with piston shafts 124 in one-to-one correspondence with the cleaning liquid injection shafts 153.

The liquid injection passage 153a penetrates the top of the cleaning liquid injection shaft 153.
With the above arrangement, the piston shaft 124 can press the cleaning liquid in the liquid injection passage 153a during the up-and-down movement of the cleaning liquid injection shaft 153, and further enhance the flow rate of the cleaning liquid flowing out to the inclined tube 200, thereby enhancing the cleaning effect. The injection passage 153a penetrates the cleaning liquid injection shaft 153 up and down to facilitate the relative movement between the piston shaft 124 and the cleaning liquid injection shaft 153.
In an alternative embodiment, the elastic member 156 includes: a fixed member 156a, a sliding member 156b, and a spring 156c. Wherein the fixing member 156a is fixedly coupled in the inner cavity 121 of the bracket 120 and above the guide ring 155. The slider 156b is located between the fixing 156a and the guide ring 155. Spring 156c is located between mount 156a and sled 156 b. The sliding member 156b is slidably connected to the fixed member 156a in a manner such as shown in fig. 9, wherein a flange 156d is provided on a side wall of the sliding member 156b, a notch 156e is provided on a side wall of the fixed member 156a into which the flange 156d is inserted, and the flange 156d is at least partially inserted into the notch 156e and is slidable in the notch 156e, so that the fixed member 156a and the sliding member 156b are prevented from rotating and form a sliding connection. The slider 156b is rotatably connected to the guide ring 155, and a rotational connection may be provided between the guide ring 155 and the slider 156b, for example, with bearings, balls, or the like, which are not shown in the drawings.
Through the adoption of the technical scheme, the fixing piece 156a and the sliding piece 156b are matched, so that the spring 156c does not need to synchronously rotate along with the cleaning liquid injection shaft 153, and further two ends of the spring 156c are not worn due to relative rotation between the cleaning liquid injection shaft 153 and the bracket 120, so that the cleaning liquid injection shaft 153 can continuously and stably move up and down.
In an alternative embodiment, the cleaning solution adapter ring 123 is provided with a solution inlet 123b in communication with the intermediate chamber 123 a. The liquid inlet 123b of the cleaning liquid transferring ring 123 and the bottom end of the cleaning channel of the cleaning liquid injecting shaft 153 are fixedly provided with a check valve 160.
Specifically, when the cleaning solution injection shaft 153 moves downward relative to the rotating shaft 151, the water in the inclined tube 200 easily enters the solution injection channel 153a, and at this time, the one-way valve 160 disposed at the cleaning solution injection shaft 153 is closed, the one-way valve 160 at the cleaning solution transfer ring 123 is opened, preventing the water in the inclined tube 200 from entering the solution injection channel 153a, and simultaneously, facilitating the replenishment of the cleaning solution from the middle chamber 123a into the solution injection channel 153 a. When the cleaning solution injection shaft 153 moves up relative to the rotating shaft 151, the one-way valve 160 arranged at the cleaning solution injection shaft 153 is opened, the one-way valve 160 at the cleaning solution adapter ring 123 is closed, and the cleaning solution is injected into the water body in the inclined tube 200 after being pressurized.
Thus, by providing the check valve 160 in the pouring channel 153a, the bottom of the pouring channel 153a can be closed to prevent the water flow in the inclined tube 200 from entering the pouring channel 153a when the cleaning liquid is replenished in the pouring channel 153a. By using the check valve 160 at the liquid inlet 123b, the liquid inlet 123b can be closed when the collar 157 presses the cleaning liquid in the intermediate chamber 123a, and the cleaning liquid can be sufficiently pressed into the liquid filling channel 153a.

The first support plate 115 is slidably disposed over the frame 114. The second support plate 116 is slidably disposed under the frame 114. The fixing block 117 is fixedly coupled between the first support plate 115 and the second support plate 116, i.e., the first support plate 115 and the second support plate 116 are coupled by the fixing member 156 a. The sliding driving member 118 is connected between the first support plate 115 and the frame 114 to drive the first support plate 115 and the second support plate 116 to slide relative to the frame 114, and specifically, the sliding driving member 118 may be, for example, a rodless cylinder, a hydraulic cylinder, etc., where the first support plate 115 is connected to a movable end of the rodless cylinder/hydraulic cylinder, so that the sliding driving member 118 can drive the first support plate 115 to slide. The bracket 120 is located below the second support plate 116, sliding the driving member 118. The elevation driving member 130 is fixedly coupled to the first support plate 115. Specifically, the elevation driving member 130 is fixed to the first support plate 115, and its bottom end passes through one of the fixing members 156a and is fixedly coupled to the bracket 120.
In this way, the first support plate 115 and the second support plate 116 slide relative to the frame 114 to drive the bracket 120 to slide relative to the frame 114. So that the rotary 150 can move in a horizontal plane. Considering that the plurality of inclined tubes 200 are generally distributed in an array of rows and columns within the settling chamber 110e, the manner in which the rotating member 150 is slidable in a horizontal plane relative to the frame 114 may enable cleaning of the plurality of inclined tubes 200 with fewer rotating members 150. The cooperation of the first support plate 115, the second support plate 116 and the fixing block 117 can limit the elevation driving member 130, so that the support 120 and the rotating member 150 installed on the support 120 move stably. The frame 114 can move up and down relative to the tank 111 so that the rotating member 150 can be further moved up and away from the tank 111, thereby facilitating the user to observe the internal condition of the inclined tube sedimentation tank 110 and also facilitating the replacement of the inclined tube 200.
