Referring to fig. 1, the embodiment relates to a backwater filtering device for a paper machine industry water pool 10, which comprises a bracket 20, a water inlet pipe 31, an inclined screen 40 and screen cloth.
In this embodiment, the support 20 is arranged in the middle of the industrial pool 10, the wall surface of the support 20 formed by pouring concrete or masonry is connected to the support 20, the two ends of the industrial pool 10 are connected to the support 20, the industrial pool 10 is divided into two parts, the two ends of the top of the support 20 along the length direction of the support 20 (namely along the axial direction of the water inlet pipe 31 on the support 20) are provided with the stop blocks 21, the thickness of the stop blocks 21 is the same as that of the wall surface of the support 20, the water inlet pipe 31 is placed above the two stop blocks 21 and is supported by the two stop blocks 21, the stop blocks 21 can support the water inlet pipe, and the water is prevented.
The inclined screen 40 is composed of a rectangular frame and a built-in metal mesh, the length of the inclined screen 40 is 10m, the height of the inclined screen is 2m, the inclination of the inclined screen is 45 degrees, the length of the inclined screen is slightly smaller than that of the support 20, the bottom of the inclined screen 40 is connected to the surface of the industrial water pool 10, and the top of the inclined screen 40 is connected to the side surface of the wall surface of the support 20, so that the inclined screen 40 is located below the water inlet pipe 31. Two sides of the bracket 20 are respectively provided with an inclined screen 40 to form a bidirectional inclined screen 40, so that the filtering efficiency is improved. The upper surface of the inclined screen 40 is covered with a layer of 100-mesh screen cloth, algae substances can be effectively filtered under the condition of ensuring water passing, and the screen cloth is detachably connected to the upper surface of the inclined screen 40 and is convenient to replace after being damaged.
The inlet tube 31 is a DN200 pipeline, 31 one end of the inlet tube is sealed, the other end is connected with the DN500 outlet pipe of the sedimentation tank, the bottom of the inlet tube 31 is uniformly provided with a plurality of water outlets, the diameter of the DN200 pipeline is smaller than that of the DN500 pipeline, the outlet pipe diameter of the inlet tube 31 relative to the sedimentation tank is reduced, the flow rate of water is increased and the pressure is increased, so that the water can be uniformly distributed in the inlet tube 31 and is full of, and the water can uniformly flow out from the water outlet at the bottom of the inlet tube 31.
Furthermore, a water tank 22 is arranged on the top of the wall surface of the bracket 20, the water tank 22 is arranged along the axial direction of the water inlet pipe 31, the water tank 22 is positioned below the water outlet of the water inlet pipe 31, and the inclined screen 40 is connected to two sides of the water tank 22. The water flowing out from the water outlet of the water inlet pipe 31 falls into the water tank 22 and then overflows from the water tank 22 and uniformly flows onto the inclined sieves 40 on the two sides, so that the phenomenon that the water directly falls onto the inclined sieves 40 from the water outlet to cause the accumulation of algae substances at one position is avoided. Furthermore, a water guide pipe is arranged at the water outlet at the bottom of the water inlet pipe 31 and extends into the water tank 22, so that water outlet from the water outlet is prevented from directly impacting on the water surface of the water tank 22 or the support 20, water splash is avoided, and water resources are wasted.
Further, a valve is arranged at the connection position of the water inlet pipe 31 and the water outlet pipe of the sedimentation tank. When the algae that accumulates on the screen cloth needs to be cleared up, the valve can be closed, the water outlet pipe 31 is stopped, and the screen cloth is conveniently cleared up or replaced to the algae on the screen cloth.
When the water treatment device works, water containing algae in the sedimentation tank is conveyed to the water inlet pipe 31 of the industrial water tank 10 through the water outlet pipe of the sedimentation tank, because the pipe diameter of the water inlet pipe 31 is reduced, the water containing algae can uniformly flow out of each water guide pipe at the bottom of the water inlet pipe 31 and fall into the water tank 22 under the action of gravity, after the water tank 22 is full, the water containing algae overflows from the water tank 22 and uniformly flows to the inclined screens 40 at two sides, under the interception effect of the mesh cloth on the inclined screens 40, the algae are intercepted on the inclined screens 40, because the inclined screens 40 incline at a certain angle, under the washing of water flow, the algae can be spread on the inclined screens 40 and slide down, the algae are easily accumulated at the bottoms of the inclined screens 40 and are convenient to clean, after the water in the sedimentation tank is filtered by the inclined screens 40, algae substances are intercepted on the inclined screens 40, the water quality is greatly improved, the blocking problem of a filter element of a paper machine is avoided, the, but also can fully utilize the surplus time to finish other works.
In some embodiments, where the industrial pond 10 is small, only one inclined screen 40 may be provided. The diameter of the water inlet pipe 31 and the diameter of the water outlet pipe of the sedimentation tank depend on the actual scale of the process and are not limited to the two specifications in the above-described embodiment. When the size of the main algae bred in the sedimentation tank is small, a mesh with 50 meshes and small meshes can be adopted, when the size of the main algae bred in the sedimentation tank is large, a mesh with 200 meshes and small meshes can be adopted, and the mesh with the size corresponding to the meshes can be selected according to the type of the algae to be processed as required.
It should be noted that, although the above embodiments have been described herein, the scope of the present invention is not limited thereby.
