Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment in chemical and metallurgical industries, and in particular to a wastewater treatment device containing industrial solid waste. Background Art

[0002] The chemical and metallurgical industries have processes such as mineral processing and coal washing, and their wastewater / sewage contains suspended matter, gravel, heavy metal ions, and soil.

[0003] Generally, the above wastewater needs to be treated at multiple levels and can only be recycled or discharged after meeting the standards. The main steps include pretreatment, main treatment, deep treatment, and post-treatment. There are two steps: pH adjustment and solid-liquid separation. pH adjustment is to adjust the acidity and alkalinity according to the composition of the wastewater to meet the requirements of the subsequent treatment process. Solid-liquid separation: solid particles in the wastewater are separated by precipitation or filtration. The above precipitation is often carried out in a sedimentation tank using the principle of natural sedimentation. The disadvantages of precipitation in a sedimentation tank are:

[0004] 1. Some floating objects cannot be removed, which puts a burden on subsequent process equipment.

[0005] 2. The gravel and soil in the sedimentation tank are mixed together after settling. Firstly, it is inconvenient to directly collect the gravel as building materials, and secondly, it brings a burden to the dredging work of the sediment at the bottom of the sedimentation tank.

[0044] The idea of the present application is to utilize a rotating gravel salvage device 20 to cyclically salvage gravel in wastewater, and the gravel salvage device 20 throws the gravel onto a slideway 30 for unified collection of the gravel.

[0045] Wastewater treatment plants containing industrial solid waste,

[0046] See Figure 1 , where the arrows represent the direction of water flow; the front end of the waterway 10 receives the wastewater, and the rear end of the waterway 10 discharges the wastewater into the sedimentation tank.

[0047] The gravel salvage device 20 includes a stone filtering end plate 21, a water trough 211, a salvage plate 22, a rotating shaft 23, and a ring plate 24; the stone filtering end plate 21 is circular and coaxially fixedly connected to the rotating shaft 23; multiple salvage plates 22 are arranged around the axis of the rotating shaft 23, and are fixedly connected to the outer peripheral wall of the rotating shaft 23 and the stone filtering end plate 21; the stone filtering end plate 21 is radially radiated with multiple water troughs 211 along its circular shape; the width of the water trough 211 is smaller than the particle size of the gravel to be salvaged.

[0048] Two support beams 40 are provided, with both ends of the rotating shaft 23 rotatably connected to the support beams 40. The support beams 40 span both sides of the waterway 10 and are fixed to the upper side of the waterway 10. The waterway 10 is provided with an arc surface, at least where the gravel catcher 20 is located. This arc surface contacts the underside of the salvage plate 22 of the gravel catcher 20. In other words, when the salvage plate 22 rotates, it can scoop up gravel trapped by the filter end plate 21. A gravel outlet 11 is provided on one side of the waterway 10, above the water surface, allowing gravel on the salvage plate 22 to slide out of the gravel outlet 11.

[0049] A rotational drive device is used to drive the rock breaker 20 to rotate along its axis. The rotational drive device can be a reduction motor, the output end of which is directly and fixedly connected to the end of the rotating shaft 23 of the rock breaker 20. Alternatively, a driving gear can be provided at the end of the reduction motor, and a driven gear can be provided at the end of the rotating shaft 23 of the rock breaker 20, with the driven gear meshing with the driving gear. Alternatively, a belt drive can be used, with pulleys provided at the ends of the reduction motor and the ends of the rotating shaft 23 of the rock breaker 20, and a belt can be placed outside the two pulleys.

[0050] In summary, the gravel salvage device 20 is used to treat wastewater before it enters the sedimentation tank; the rotating salvage plate 22 of the gravel salvage device 20 salvages the wastewater and throws it out from the gravel outlet 11; the gravel can be easily collected at the gravel outlet 11; for the wastewater treatment field of the chemical and metallurgical industries, the purpose of separating gravel from the wastewater on the front side of the sedimentation tank is achieved.

[0051] Furthermore, the wastewater contains a small amount of floating matter.

[0052] The floating object blocking box 60 is fixed with shoulders 62 on both sides, and the shoulders 62 are installed together with the waterway 10; the shoulders 62 define a water inlet 61, the lowest point of which is submerged 1-2 cm below the water surface; the floating object blocking box 60 is provided with a water hole 63 on the opposite side of the water inlet 61.

[0053] Furthermore, a downward protrusion is provided on the lower side of the shoulder 62; the waterway 10 is provided with a groove for accommodating the protrusion; the protrusion and the groove are embedded and matched to fix the shoulder 62.

[0054] Furthermore, guardrails are provided on both sides of the slide 30 , and one end of the slide 30 is connected to the gravel outlet 11 ; the gravel coming out of the gravel outlet 11 can slide down the slide 30 , and the lower end of the slide 30 can collect the gravel. Example

[0055] See Figures 4 to 6Because the gravel is irregular, one end of the conical gravel is stuck in the water trough 211, and the other end cannot pass through the water trough 211 and is stuck, and the water outlet of the direct filter stone end plate 21 is not smooth; in order to solve this problem, an improvement is made.

[0056] The difference between the second embodiment and the first embodiment is that it further includes an anti-jamming device 90 and a linear drive module 100;

[0057] The anti-stuck device 90 specifically includes a cleaning block 91, a connecting rod 92, a connecting head 93, and a sliding sleeve 94; wherein the cleaning block 91 is slidably arranged in the water trough 211; the connecting head 93 is inserted into the outer side of the rotating shaft 23, and the connecting head 93 is on the side of the filter end plate 21 away from the salvage plate 22; the two ends of the connecting rod 92 are respectively pivotally connected to the connecting head 93 and the two ends of the cleaning block 91; that is, in the process of pushing the connecting head 93, the cleaning block 91 slides in the water trough 211 and squeezes the stuck gravel out of the water trough 211, and then almost all of it is thrown out from the gravel outlet 11.

[0058] The linear drive module 100 is used to push the connecting head 93 back and forth; the linear drive module 100 includes a sliding sleeve 94, a driving member 110, a slide plate 120, a slide 121, and a pushing plate 130; the sliding sleeve 94 slides through the outside of the rotating shaft 23, the sliding sleeve 94 is in the hole of the connecting head 93, and the connecting head 93 and the sliding sleeve 94 are directly connected through a bearing; the driving member 110 is a linear reciprocating driving member, which can be an electric cylinder, a hydraulic cylinder or an air cylinder; the pushing plate 130 is fixedly connected to the sliding sleeve 94; the outer wall of the driving member 110 is fixedly set, and the driving component of the driving member 110 is fixedly connected to the pushing plate 130. The linear extension and contraction of the driving member 110 can make the clearing block 91 slide in the stone filter end plate 21, thereby completing the action of clearing the gravel stuck in the stone filter end plate 21.

[0059] Furthermore, in order to make the movement of the push plate 130 smoother, a fixed chute plate 120 is set on both sides of the waterway 10, and the chute plate 120 has a chute 121 along the axis of the rotating shaft 23; the push plate 130 is provided with a protruding slider, which is slidably set in the chute 121.

[0060] Furthermore, the water pressure sensor 200 is disposed between the floating object blocking box 60 and the gravel salvage device 20 , and the water pressure sensor 200 is below the water surface;

[0061] When too much gravel is stuck in the water channel 211 of the stone filtering end plate 21, the water flow rate of the stone filtering end plate 21 becomes smaller, the water where the water pressure sensor 200 is located accumulates and the water level rises; the water pressure sensor 200 can monitor the water pressure in real time.

[0062] The controller is used to receive the signal from the water pressure sensor 200; and the controller can control the sliding of the connector 93 through the signal, thereby starting the work of clearing the stuck gravel.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
