Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:

a high-speed mixed bed with the function of reducing the loss of fine processing resin is shown in figure 1 and comprises a bracket 1, a box body 2, an upper porous plate 3, a water inlet cap 4, a lower porous plate 5 and a water outlet cap 6.

The box body 2 is arranged on the bracket 1, and the box body 2 is provided with an upper water inlet 21, a lower water outlet 22, a resin inlet 23, a resin outlet 24 and an exhaust port 25. The stand 1 provides the tank 2 with a certain height so as to facilitate discharge from the bottom end of the tank 2 for use.

Go up the perforated plate 3 and set up in box 2, go up the perforated plate 3 and be located the below of going up inlet of a river 21, inlet cap 4 sets up the below at last perforated plate 3. Go up the porous plate 3 and can cushion the water that gets off from last inlet opening 21, inlet cap 4 is equipped with small-size through-hole, is convenient for lead to the box 2 with the water on the porous plate 3 in.

The lower porous plate 5 is arranged in the box body 2 and is positioned below the upper porous plate 3, the lower porous plate 5 is positioned above the lower water outlet 22, and the resin outlet 24 is communicated with the lower porous plate 5 through a pipeline.

The resin outlet 24 can directly discharge the resin above the lower perforated plate 5. The water outlet cap 6 is arranged above the lower porous plate 5, and the water outlet cap 6 and the lower porous plate 5 have a certain height which is used for preventing the resin in the condensed water from blocking the water outlet cap 6. When water flows out of the water outlet cap 6, a certain attraction force is generated, and the resin is likely to block the water inlet of the water outlet cap 6. Here, the outlet cap 6 has a certain height, and the condensed water at the bottom end of the lower porous plate 5 can make the resin flow along with the condensed water during the flowing process, so as to avoid the blockage of the inlet of the resin at the outlet cap 6. Preferably, lower perforated plate 5 is the arch of downward jut, and the face of play water cap 6 and lower perforated plate 5 sets up perpendicularly, and the through-hole of perforated plate 5 under the pressure impact of condensate can be avoided to this shape, reduces the damage of condensate to lower perforated plate 5. Go up the perforated plate 3 and be the plane shape, the face of intaking water cap 4 and last perforated plate 3 sets up perpendicularly, plays the effect to the perforated plate 5 step-down. The below of lower perforated plate 5 is equipped with water-collecting sheet 7, and lower delivery port 22 passes through pipeline and water-collecting sheet 7 intercommunication, and the effect of erosion to box 2 of minimizing can increase box 2's life through this design, when water-collecting sheet 7 damaged, only need to change water-collecting sheet 7 can. A plurality of support frames 8 are arranged between the bottom surface of the lower porous plate 5 and the water collection plate 7, so that the support strength of the water collection plate 7 is improved.

Further, the resin inlet port 23 is located between the upper perforated plate 3 and the lower perforated plate 5, and the resin outlet port 24 is located below the lower perforated plate 5. The exhaust port 25 is located above the upper porous plate 3. The top end of the box body 2 is provided with a lifting lug 9 for lifting the box body 2.
