Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a multi-stage filtering device for recovering scum from production wastewater. Background Art

[0002] When recycling production wastewater, it is necessary to separate the scum on its surface. First, the generated wastewater is pretreated to remove large particles of impurities and solid waste to reduce the burden of subsequent treatment processes. Then, the scum in the wastewater is separated from the water by physical or chemical methods, and then the separated scum is recycled. In the process of separating scum from water, a problem is prone to occur, that is, the water flow speed is too fast. During the scum deposition process, it is easy to be driven by the high-speed flowing water, resulting in incomplete scum deposition, causing part of the scum to flow with the water flow, affecting the effect of scum recovery treatment.

[0003] Therefore, a multi-stage filtering device for recovering wastewater scum is now developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that are easily driven by high-speed flowing water during the scum deposition process, resulting in incomplete scum deposition, causing part of the scum to flow with the water flow, and affecting the scum recovery and treatment effect, the utility model provides a multi-stage filtering device for recovering production wastewater scum.

[0006] In one of the embodiments, a standing mechanism is also included, which includes a slide rail, and the slide rail is connected to the left and right side walls of the right front chamber of the chamber platform, and two push plates are slidably arranged on the slide rail, and two locking parts for locking and limiting the push plates are slidably arranged on the slide rail.

[0007] In one embodiment, the length of the first filter plate at the front side is greater than that of the first filter plate at the rear side.

[0008] In one of the embodiments, the guide plate is an inclined structure.

[0009] In one embodiment, the second filter plate has handles on both the front and rear upper sides.

[0010] In one embodiment, the sinking assembly includes a guide rod, a sinking plate and a spring. The guide rod is connected to the middle position of the bottom of the installation box. The sinking plate is slidably arranged on the guide rod. A spring is connected between the sinking plate and the installation box.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model uses the guide plate to make the wastewater drive the scum to gather in the installation box, so that the scum can be deposited under the blocking and filtering action of the second filter plate, and at the same time relies on the sinking component to limit the flow speed of the wastewater, to avoid the wastewater flowing too fast during the filtering process to cause the scum to flow out with the wastewater, thereby improving the deposition effect of the scum, and after the scum treatment is completed, the wastewater is guided back to the cavity table by the water pipe, so as to facilitate centralized wastewater treatment.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] Example 1

[0019] A multi-stage filtration device for recovering scum from production wastewater, such as Figure 1As shown, it includes a chamber platform 1, two first filter plates 2 are installed on the left side of the chamber platform 1, the length of the first filter plate 2 on the front side is greater than that of the first filter plate 2 on the rear side, and the right side of the chamber platform 1 is connected to a guide plate 3 for guiding the water flow, and the guide plate 3 is an inclined structure. A valve 4 is slidingly arranged on the right side of the chamber platform 1, and a scum recovery mechanism 5 for recovering scum floating on the upper surface of wastewater is arranged on the right side of the rear side of the chamber platform 1.

[0020] like Figure 1 and Figure 2 As shown, the scum recovery mechanism 5 includes an installation box 51, which is installed on the right side of the rear part of the cavity platform 1 by bolts, and a second filter plate 52 for blocking and limiting the scum is slidably arranged in the installation box 51, and the second filter plate 52 is provided with handles on the upper sides of the front and rear parts, and a sinking component 53 for slowing down the water discharge speed is arranged in the installation box 51, and the sinking component 53 includes a guide rod, a sinking plate and a spring, and the guide rod is connected to the middle position of the bottom of the installation box 51, and a sinking plate is slidably arranged on the guide rod, and a spring is connected between the sinking plate and the installation box 51, and a water pipe 54 is connected between the front side of the lower part of the installation box 51 and the cavity platform 1.

[0021] It should be noted that when treating production wastewater, it is necessary to separate the scum on its surface. First, the wastewater is introduced into the left side of the chamber platform 1 through the guiding device, so that the wastewater is filtered through the first filter plate 2 to filter out some larger solid impurities. After that, the wastewater will flow to the right under the guidance of the guide plate 3 and gradually form a convergence state, so that the scum enters the installation box 51 and is deposited on the second filter plate 52. At this time, under the blocking effect of the sinking plate in the sinking assembly 53, the water flow in the installation box 51 will slowly squeeze the sinking plate, causing the sinking plate to slowly descend, thereby preventing the water flow from sinking too fast, causing the deposited scum to be driven out, and the outflowing wastewater will enter the lower part of the installation box 51 and The wastewater is guided by the water pipe 54 and returns to the chamber 1. When the scum is processed, the valve 4 is pulled upward to open so that the wastewater in the chamber 1 is collected in the chamber at the right front part of the chamber 1 and stored. Finally, the operator uses the pumping equipment to pump out the stored wastewater. In summary, the guide plate 3 is used to make the wastewater drive the scum to gather in the installation box 51, so that the scum can be deposited under the blocking and filtering effect of the second filter plate 52. At the same time, the flow rate of the wastewater is limited by the sinking component 53 to avoid the wastewater flowing too fast during the filtration process, causing the scum to flow out with the wastewater, thereby improving the scum deposition effect. After the scum is processed, the wastewater is guided back to the chamber 1 by the water pipe 54 to facilitate centralized wastewater treatment.

[0022] Example 2

[0023] On the basis of Example 1, Figure 1 and Figure 3As shown, it also includes a standing mechanism 6, which includes a slide rail 61. The slide rail 61 is connected to the left and right side walls of the right front chamber of the chamber platform 1. Two push plates 63 are slidably arranged on the slide rail 61. Two locking members 62 for locking and limiting the push plates 63 are slidably arranged on the slide rail 61.

[0024] It should be noted that during the wastewater treatment process, the operator can stand on the push plate 63 to observe the treatment process, so as to facilitate subsequent adjustments. After the treatment is completed, the operator stands on the push plate 63 to pull the valve 4 upward to open it, and then pulls the locking piece 62 upward to unlock the push plate 63, and then slides the push plate 63 open so that the chamber on the right front of the chamber platform 1 is no longer blocked, and finally uses the pumping equipment to pump out the wastewater.

Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention.
