Description

Technical Field

[0001] The utility model relates to the technical field of grinding fluid recovery equipment, in particular to a grinding fluid recovery device for a roll grinder. Background Art

[0002] When the roll grinder is performing processing work, a large amount of grinding heat will be generated due to the long-term friction between the grinder and the roll. The high heat generated will cause serious wear on the roll and the grinder, thereby reducing the quality of roll processing and the life of the grinder. In order to avoid this situation, grinding fluid is generally used for physical cooling during grinding work. When the grinding fluid is in use, it is directly pumped to the grinding site through a conduit. The flow of the grinding fluid will take away the heat generated by friction, and the grinding fluid after cooling will flow into the collection tank for recycling. While cooling the grinding fluid, it sometimes brings the waste chips generated by grinding into the collection tank. If these waste chips are not filtered, they will cause damage to the circulation pump. The current filtering method generally uses a partition net to block the waste chips. When the waste chips are subsequently cleaned, the staff is required to clean the entire grinding fluid tank, which greatly increases the workload of the staff and brings great inconvenience to production work.

[0018] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4 As shown, a grinding fluid recovery device for a roll grinder described in this embodiment includes a recovery tank 1, a delivery pipe 2 for delivering grinding fluid extends into the recovery tank 1, a filter 3 is provided at one end of the delivery pipe 2 located in the recovery tank 1, a radiator 4 is provided in the recovery tank 1 at a position corresponding to the lower end of the filter 3, a circulation pump 5 is also provided in the recovery tank 1, and a circulation pipe 6 for pumping out the grinding fluid in the recovery tank 1 is provided on the circulation pump 5;

[0021] One end of the delivery pipe 2 located in the recovery tank 1 and the top of the filter 3 are both provided with a mounting flange 7, and the two mounting flanges 7 are fixedly connected by a retaining pin 8;

[0022] The retaining pin 8 includes a pin rod 81 that penetrates the two mounting flanges 7 simultaneously in the vertical direction, and a rod head 82 is provided at the upper end of the pin rod 81, and the rod head 82 abuts against the upper end of the mounting flange 7 on the conveying pipe 2, and a retaining ring 83 that can be offset to the outside of the pin rod 81 is provided at the lower end of the pin rod 81, and the upper end surface of the offset retaining ring 83 abuts against the lower end surface of the mounting flange 7 on the filter 3.

[0023] The lower end of the pin rod 81 is provided with a boss 84 extending outward from the mounting flange 7 on the filter 3, and the diameter of the boss 84 is smaller than the diameter of the pin rod 81. The snap ring 83 is sleeved on the boss 84. The outer diameter of the snap ring 83 is the same as the diameter of the pin rod 81 and the inner diameter of the snap ring 83 is larger than the diameter of the boss 84. The lower end of the boss 84 is provided with a locking cap 85 for fixing the snap ring 83 in place.

[0024] A threaded rod 86 is disposed at the upper end of the locking cap 85 , and a threaded hole is disposed at the lower end of the boss 84 . The locking cap 85 is locked in the threaded hole through the threaded rod 86 .

[0025] When installing the filter 3, firstly, the mounting flange 7 on the filter 3 is connected with the mounting flange 7 on the conveying pipe 2, and then the pin rod 81 is used to penetrate the two mounting flanges 7. When the rod head 82 abuts against the upper end surface of the upper mounting flange 7, the end of the pin rod 81 with the boss 84 just extends out from the lower end surface of the lower mounting flange 7. Then, the locking cap 85 is loosened to release the restriction on the snap ring 83. Then, the snap ring 83 is moved to make one side extend outward of the pin rod 81. At this time, the snap ring 83 is eccentric relative to the pin rod 81, and the upper edge of the extended snap ring 83 abuts against the lower end surface of the lower mounting flange 7. Then, the locking cap 85 is tightened to fix the eccentric snap ring 83 in place. At this time, the filter 3 is fixedly connected to the conveying pipe 2. When it needs to be disassembled and cleaned, it only needs to loosen the locking cap 85 again and reset the snap ring 83 to a position coaxial with the pin rod 81, so that the retaining pin 8 can be removed, thereby removing the filter 3 for cleaning.

[0026] The filter 3 comprises a hollow filter cartridge 31 , a lower mounting flange 7 is arranged at the top of the filter cartridge 31 , a filter screen 32 is arranged at the opening at the bottom of the filter cartridge 31 , and waste chips in the grinding fluid are blocked by the filter screen 32 .

[0027] The radiator 4 includes a wave-shaped partition plate 41 , and a plurality of drainage ports 42 are evenly distributed on a flat plate at the bottom of the partition plate 41 .

[0028] The partition plate 41 is provided with a surrounding plate 43 at its outer periphery, and the surrounding plate 43 is arranged vertically upward.

[0029] The radiator 4 blocks the filtered grinding fluid, and the flowing grinding fluid first falls on the partition 41, and then flows down from the discharge port 42 on the partition 41, so that the grinding fluid can be diverted. In this way, the grinding fluid with a small flow rate will be cooled in the process of falling into the recovery tank 1, thereby facilitating the subsequent use of the grinding fluid.

[0030] A support rod 9 is provided on the inner wall of the recovery tank 1 , and the filter 3 is installed on the upper end of the support rod 9 .

[0031] The working principle of the utility model is as follows: the grinding fluid used for cooling is recovered by the collecting tank, and then transported to the recovery tank 1 through the transport pipe 2. The grinding fluid will first be filtered through the filter 3 to filter out the waste chips mixed inside, and then the filtered grinding fluid will flow to the radiator 4. Subsequently, the grinding fluid will be diverted through the radiator 4 and fall into the recovery tank 1. At this time, the diverted grinding fluid will be fully cooled in the process of flowing down, thereby facilitating the reuse of the grinding fluid. The grinding fluid after filtering and heat dissipation will finally be pumped out through the circulation pump 5 and transported to the grinding station through the circulation pipe 6 for cooling.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
