Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a cooling water regulating device for a cement grinding roller press. Background Technology

[0002] Roller presses, also known as calenders, double-roll mills, rolling mills, extrusion mills, and roller mills, can replace the pre-grinding system of ball mills, which have high energy consumption and low efficiency. In order to avoid the roller press from overheating during use, cooling water is required to cool it down. At the same time, in order to keep the cooling water at a suitable temperature, cooling water regulating equipment is used to cool the cooling water.

[0003] Because roller presses operate at high temperatures, scale easily forms on the inner walls of the rollers. Vibration during operation causes this scale to flake off. Since existing roller press cooling water regulating equipment lacks a corresponding filtration mechanism, this scale can enter the heat exchanger, affecting its performance. Therefore, we propose a cooling water regulating device for cement mill roller presses. Utility Model Content

The vertical plate matches the internal dimensions and structure of the filter box. A through hole is opened on the vertical plate, and an installation groove is opened on the inner wall of the through hole. A filter plate is placed in the installation groove.

[0008] Preferably, the first connecting pipe is a copper pipe, and multiple heat dissipation fins are provided on the first connecting pipe. A fan is installed on the outer wall of the filter box, and the air outlet of the fan corresponds to the position of the first connecting pipe.

The other end of the first connecting pipe 8 is connected to the plate heat exchanger 2. The inlet and outlet ends of the pump body 5 are respectively fixedly connected to a second connecting pipe 9 and an outlet pipe 7. The other end of the second connecting pipe 9 is connected to the plate heat exchanger 2. The filter box 4 is provided with a cover plate 15. A vertical plate 18 is fixedly connected to the bottom outer wall of the cover plate 15. The vertical plate 18 matches the internal dimensions and structure of the filter box 4. A through hole is opened on the vertical plate 18. An installation groove 19 is opened on the inner wall of the through hole. A filter plate 20 is placed in the installation groove 19.

[0027] This utility model discloses a cooling water regulating device for a cement mill roller press. The first connecting pipe 8 is a copper pipe with multiple heat dissipation fins 10. A fan 11 is installed on the outer wall of the filter box 4. The air outlet of the fan 11 corresponds to the position of the first connecting pipe 8, which can provide a preliminary cooling effect for hot water, thereby improving the cooling efficiency of hot water.

[0028] The present invention relates to a cooling water regulating device for a cement mill roller press. A support seat 12 is provided on the bottom outer wall of the base plate 1. There are four support seats 12, which are evenly distributed at the four corners of the bottom of the base plate 1. They can provide stable support and thus ensure the stability of the entire device during use.

[0029] This utility model discloses a cooling water regulating device for a cement mill roller press. The filter box 4 has a slot 13, and the bottom outer wall of the cover plate 15 has an insert plate 22. The size and position of the insert plate 22 correspond to those of the slot 13. A waterproof sealing ring is bonded to the bottom outer wall of the insert plate 22, which can improve the sealing between the cover plate 15 and the filter box 4 and prevent water leakage.

[0030] The present invention relates to a cooling water regulating device for a cement mill roller press. A lower fixing block 14 is provided on the outer wall of the filter box 4, and a screw hole is provided on the lower fixing block 14. An upper fixing block 16 is provided on the outer wall of the cover plate 15, and a limit bolt 17 is rotatably connected to the upper fixing block 16. The position of the limit bolt 17 corresponds to the screw hole, which can provide a stable installation effect for the cover plate 15.

[0031] This utility model discloses a cooling water regulating device for a cement mill roller press. A rotating rod is welded to the outer wall of the rotating head of the limiting bolt 17, and a rubber sleeve is nested on the rotating rod. This allows the operator to manually rotate the limiting bolt 17 without the need for any tools, thus improving ease of use.

[0032] This utility model discloses a cooling water regulating device for a cement mill roller press. Two baffles 21 are rotatably connected to the outer wall of the vertical plate 18. The two baffles 21 are symmetrically arranged on both sides of the mounting groove 19. A return spring is provided at the rotatable connection between the baffle 21 and the vertical plate 18, which can provide a limiting effect for the filter plate 20 and prevent the filter plate 20 from separating from the vertical plate 18 during use, thus affecting the use effect.

[0033] The present invention relates to a cooling water regulating device for a cement mill roller press. A collection frame 23 is provided on the outer wall of the vertical plate 18 near the water inlet pipe 6. The collection frame 23 is matched with the size and structure of the filter box 4. When the filter plate 20 is replaced, it is convenient to carry the floating scale inside the filter box 4 to the outside for treatment.

[0034] In use, the inlet pipe 6 is connected to the hot water outlet of the cement roller press, and the outlet pipe 7 is connected to the inlet of the cement roller press. During operation, the pump body 5 delivers cooling water to the interior of the cement roller press to provide cooling. The cooling water, after absorbing heat and increasing in temperature, enters the filter box 4 through the inlet pipe 6. At this time, the filter plate 20 filters the cooling water, intercepting scale. The filtered cooling water then enters the plate heat exchanger 2 through the first connecting pipe 8 for further cooling (the plate heat exchanger 2 is existing technology and will not be discussed in detail here). As the cooling water passes through the first connecting pipe 8, some of its heat is dissipated to the outside through the heat dissipation fins 10. Furthermore, the operation of the fan 11 can increase the heat dissipation rate. As the usage time increases, the filter plate 20 will become clogged. At this time, the filter plate 20 needs to be cleaned or replaced. When disassembling the filter plate 20, simply turn the rotating rod to disengage the limiting bolt 17 from the lower fixing block 14. At this time, the cover plate 15 loses its fixing effect and can be removed. During the removal of the cover plate 15, the scale floating in the water can be carried to the outside by the collecting mesh frame 23. When the vertical plate 18 is completely moved to the outside of the filter box 4, rotate the baffle 21 to remove its limiting effect on the filter plate 20, and then disassemble the filter plate 20. When installing the filter plate 20, repeat the above steps.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
