Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a circulating water recovery device. Background Art

[0002] In the processing and production of wood and wood boards, a large amount of saw blade cutting operations are required; during this process, it is necessary to cool down the saw blade and the motor to keep them in a good working state. In order to reduce resource consumption, the form of circulating water is mostly adopted; during the circulation process of the cooling water, some impurities will be mixed in. Therefore, corresponding designs are needed for the recovery of circulating water.

[0003] For example, the patent with the application number "CN202311702453.4" discloses a cooling tower circulating water filtration and recovery device, which includes a recovery device body. The top of the recovery device body is detachably connected with a top cover. A pressing plate is slidably and horizontally arranged inside the recovery device body, and a matching lower sealing retaining ring is horizontally and fixedly installed at the bottom inside the recovery device body. A matching filter element is installed above the lower sealing retaining ring, and an upper sealing retaining ring is horizontally arranged at the top of the filter element. The upper sealing retaining ring is fixedly installed on the inner wall of the recovery device body, and a slope structure is provided at the top of the upper sealing retaining ring. A cleaning and sewage discharging component for cleaning the filter element is arranged on the pressing plate; it can continue to use the recovery device body while discharging sewage from the recovery device body and cleaning the filter element without stopping the machine operation, making the use more stable. And during sewage discharge, the impurities blocked on the inner wall of the filter element can be synchronously cleaned and discharged through the sewage discharge pipe. The patent with the application number "CN202223477251.8" discloses a sewage filtration and recovery device, which includes a treatment tank. A recovery cover is arranged at the middle position of the treatment tank. A drain pipe is arranged on one side of the recovery cover. An upper ring seat and a lower ring seat are respectively movably installed at both ends inside the treatment tank. A connecting rod is fixedly installed between the upper ring seat and the lower ring seat. A support frame is fixedly installed inside the lower ring seat. A filter mesh cover is inserted between the upper ring seat and the lower ring seat. The lower end of the filter mesh cover is in contact with the upper end of the support frame. The driving motor drives the transmission rod to rotate. The transmission rod drives the upper ring seat and the lower ring seat to rotate through the transmission gear and the transmission gear ring, so that the filter mesh cover rotates. The clamping gear at the lower end of the rotating shaft is inserted into the clamping tooth seat, so that the rotating shaft cannot rotate. Then the rotating shaft comprehensively cleans the inner wall of the filter mesh cover through the stirring frame, avoiding the blockage of the filter mesh cover and affecting the filtering effect.

[0004] The above technical solution and the conventional circulating water recovery devices currently on the market can all achieve the treatment and recovery of circulating water; moreover, they mostly filter impurities in the form of a filter screen, which has corresponding practicality. However, their structures are often relatively complex, resulting in inconvenient maintenance; at the same time, the collection and cleaning of the filtered impurities are also not very convenient; it is also not easy to keep track of the quantity of the filtered debris at any time. In addition, precipitation is required during the recovery of circulating water; the depth of the conventional precipitation area is relatively large, occupying a large volume; and the water flow impacts the water surface, easily causing the sediment at the bottom to float up.

[0035] Correspondingly, a water outlet pipe 12 is arranged on the side of the recovery tank 1, and a sediment discharge pipe 13 is arranged at the bottom; through the water outlet pipe 12 arranged at a position close to the lower side on the side, the treated water is discharged and enters the cycle again; the lowermost sediment discharge pipe 13 is used to discharge the sediment at the bottom to the outside.

[0036] An upwardly convex filter screen 2 is arranged above the interior of the recovery tank 1 to filter out impurities in the water flow; at the same time, the filter screen 2 extends to the outside of the recovery tank 1, and an impurity outlet 3 corresponding to the upper position of the filter screen 2 is circumferentially opened on the side wall of the recovery tank 1; for discharging impurities; moreover, the impurities are all exposed outside, and personnel can directly see the current amount of filtered impurities.

[0037] As Figures 2-7 shown; the water flow falls from above and lands on the inclined filter screen 2, and the impurities are filtered out; at the same time, with the scouring of the water flow and the inclined state of the filter screen 2, the impurities are pushed to the outer ring side at the lower end, and along the surface of the filter screen 2 and through the impurity outlet 3, they reach the outer area of the filter screen.

[0038] At the same time, a return water ring plate 4 is arranged outside the recovery tank 1 at a position below the filter screen 2, and a return water port 5 is opened on the side wall of the recovery tank 1 at a position corresponding to the upper position of the return water ring plate 4.

[0047] In some embodiments, a spiral blade 8 is provided at the lower position inside the recovery tank 1 to prevent the water flow from falling directly and impacting the sediment part below; and, the depth of the sediment can be reduced, saving the occupied area.

[0048] Among them, the number of spiral turns of the spiral blade 8 is not less than 1.5 turns to form an effective block and have a longer path.

[0049] Preferably, the height of the sediment water area below is higher than the lowest end of the spiral blade 8.

[0050] Correspondingly, the water outlet pipe 12 is located at the lower position of the spiral blade 8.

[0051] In some embodiments, a maintenance opening 9 is provided at the top of the recovery tank 1.

[0052] When the utility model is in use, the recycled water used externally is collected into the recovery tank 1 through the water inlet pipe 11; the water flow entering from the upper part is collected to the central position by the collecting hopper 6 and then falls on the filter net 2; the sundries are discharged outwards and the water falls downwards; then, the water falls on the spiral blade 8 and is guided to flow downwards; sediment is formed in the sediment area, and at the same time, the upper layer of water is led out by the water outlet pipe 12.

[0053] In the utility model, the water inlet pipe 11 can introduce multiple circulating water at the same time, and recycle it after centralized treatment, which saves the number of recycling tanks 1, reduces the overall occupied area, and is convenient for centralized maintenance; the upwardly protruding filter screen 2 cooperates with the impurity outlet 3 to filter the impurities to the outside, and the current amount of impurities can be intuitively seen; the position return water ring plate 4 cooperates with the return water outlet 5 to recycle again, and the up and down moving baffle ring 7 cooperates to form a barrier or impurity discharge; the gathering bucket 6 gathers the water flow of each pipeline to the central position, corresponding to the highest end of the filter screen 2, for better filtering; spiral blades 8 are provided to prevent the water flow from falling directly and impacting the sedimentation part below; and the depth of the sedimentation can be reduced, saving the occupied area.
