Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a cooling screening device for biochemical industry. Background Art

[0002] Biochemical engineering is an interdisciplinary subject consisting of biology, chemistry, engineering and other disciplines. It studies the basic theories and engineering technologies in processes involving organisms or bioactive substances. Biochemical materials need to be screened during processing. During material screening, a cooling screening device is usually required to cool the screened materials with fan wind power.

[0003] At present, when cooling and screening biochemical materials, air-cooled vibrating screens are usually used to cool and screen the materials. However, this vibrating screen usually only has a few fans at the cover box above the screen seat to cool the biochemical materials on the screen surface. Since the fans are close to the cover box, the cover box dissipates heat outward under the influence of the thermal radiation of the materials. At this time, the temperature of the wind blown in by the fans near the cover box will also be affected by the temperature dissipated by the materials, resulting in the biochemical materials being unable to be effectively cooled during screening. For this reason, we propose a cooling screening device for biochemical industry. Utility Model Content

[0004] The main purpose of the utility model is to provide a cooling screening device for biochemical industry, in which an exhaust fan and a cooling mechanism are arranged at the cover box of the vibrating screen body, and the cooling mechanism is connected to the external circulating water supply equipment through the pipe structure arranged in the transfer box, so that there are low-temperature pipes in the transfer box, and then the transfer box uses the air inlet fan to blow the cold air formed by the low-temperature pipe into the vibrating screen body below the cover box to cool the biochemical materials, and the hot air rising in the cover box can be sucked away by the exhaust fan and discharged to the outside, thereby ensuring the efficient cooling of the biochemical materials inside the vibrating screen body, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cooling screening device for biochemical industry, comprising a vibrating screen body and a cover box, wherein a cover box is installed above the seat of the vibrating screen body, and further comprising an exhaust fan, an oblique inlet and a cooling mechanism. The exhaust seat of the cover box is fastened with bolts to an exhaust fan for guiding the heat inside the exhaust port to be discharged outwards, and the flat box wall surface of the cover box away from the exhaust fan is symmetrically provided with an oblique inlet. The cooling mechanism comprises a curved conduit, a transfer box, an air inlet, a connecting pipe, a U-shaped connecting pipe, a return flow pipe and an L-shaped support leg, and an oblique pipe with a curved conduit is inserted into the oblique inlet. The transfer box has an L-shaped support leg fixed to the bottom of the box body, and the L-shaped support leg is fixed to the cover box surface by bolts.

[0007] Furthermore, the air inlet of the exhaust fan faces the heat exhaust port of the cover box, and the seat plate of the exhaust fan and the heat exhaust seat raised on the surface of the cover box are locked by bolts;

[0008] By adopting the above technical solution, the exhaust fan can exhaust the hot air upward from the heat exhaust port of the cover box.

[0009] Furthermore, four groups of side-facing holes are symmetrically opened on the opposite vertical box walls of the transfer box, and two groups of pipe bodies with connecting pipes and straight pipe bodies of U-shaped connecting pipes are respectively inserted and welded into the four groups of side-facing holes.

[0010] By adopting the above technical solution, the transfer box can be connected to the two groups of pipe bodies of the connecting pipe and the straight pipe body of the U-shaped connecting pipe by welding the four groups of side holes.

[0011] Furthermore, the two straight pipe openings of the U-shaped connecting pipe are welded to the two pipe bodies of the return flow pipe, and the other end of the return flow pipe away from the U-shaped connecting pipe is welded to the two pipe bodies of the connecting pipe;

[0012] By adopting the above technical solution, the U-shaped connecting pipe and the butt-connecting pipe are welded with two groups of return flow pipes to form a pipe body that can reflux cooling water.

[0014] By adopting the above technical solution, the L-shaped legs below the transfer box are fastened to the surface of the cover box by bolts to provide support for the transfer box.

[0015] Furthermore, the transfer box is a hollow box with box holes symmetrically opened on both sides of the box body, and the diameter of the box hole is the same as the diameter of the straight tube body of the curved conduit;

[0016] By adopting the above technical solution, the middle hole box body of the transfer box can accommodate the return deflection pipe, and the straight pipe body of the curved pipe can be inserted into the box hole of the transfer box for welding.

The cooling mechanism is connected to the external circulating water supply equipment through the pipe structure provided in the transfer box, so that there is a low-temperature pipe in the transfer box. Then, the transfer box uses the air inlet fan to blow the cold air formed by the low-temperature pipe into the vibrating screen body below the cover box to cool the biochemical materials. The hot air rising in the cover box can be sucked away by the exhaust fan and discharged to the outside, thereby ensuring the efficient cooling of the biochemical materials inside the vibrating screen body.

[0019] And because there is a pipe structure at the transfer box that can circulate cooling water, and the air inlet fan can be connected to the cover box at a distance through the transfer box and the curved duct, the heat in the cover box will not affect the air supply temperature of the air inlet fan when it radiates outward.

Side holes 11 for inserting connecting pipes 12 and U-shaped connecting pipes 13 are opened on the outside of the vertical walls on both sides of the transfer box 7. The connecting pipes 12 and U-shaped connecting pipes 13 extend into the pipe body of the transfer box 7 and are communicated with each other by welded return flow pipes 14. An L-shaped support leg 15 is fixed to the bottom of the box body of the transfer box 7, and the L-shaped support leg 15 is locked to the surface of the cover box 2 by bolts.

[0027] The air inlet of the exhaust fan 3 faces the heat exhaust port of the cover box 2, and the seat plate of the exhaust fan 3 is locked with the heat exhaust seat raised on the surface of the cover box 2 by bolts;

[0028] By adopting the above technical solution, the exhaust fan 3 can exhaust the hot air upward from the heat exhaust port of the cover box 2.

[0029] The side holes 11 are symmetrically opened in four groups on the vertical box wall opposite to the transfer box 7, and the four groups of side holes 11 are respectively inserted and welded with two groups of connecting pipes 12 and a straight pipe body of a U-shaped connecting pipe 13;

[0030] By adopting the above technical solution, the transfer box 7 can be connected to the two groups of pipe bodies of the connecting pipe 12 and the straight pipe body of the U-shaped connecting pipe 13 by welding the four groups of side holes 11.

[0031] The two straight pipe openings of the U-shaped connecting pipe 13 are welded to the two pipe bodies of the return flow pipe 14, and the other end of the return flow pipe 14 away from the U-shaped connecting pipe 13 is welded to the two pipe bodies of the connecting pipe 12.

[0033] The vertical frame plate of the L-shaped support leg 15 is welded to the lower surface of the transfer box 7, and a mounting hole for screwing bolts is opened between the bottom frame plate surface of the L-shaped support leg 15 and the cover box 2;

[0034] By adopting the above technical solution, the L-shaped legs 15 below the transfer box 7 are fastened to the surface of the cover box 2 by bolts to provide support for the transfer box 7 .

[0035] The transfer box 7 is a hollow box with box holes 8 symmetrically opened on both sides of the box body, and the diameter of the box hole 8 is the same as the diameter of the straight tube body of the curved conduit 6;
