Description

Technical Field

[0001] The utility model belongs to the technical field of cooling liquid filtering devices, and in particular relates to a solid filtering device. Background Art

[0002] In the process of silicon wafer cutting, the use of coolant is very critical. The coolant can not only help reduce the heat generated by the silicon wafer during the cutting process and improve the cutting efficiency, but also prevent the blade from overheating and extend the service life of the blade. However, during the cutting process, some silicon rod powder, silicon rod fragments or broken metal wires will be mixed into the coolant. During the use of the coolant, a large amount of solid particles will be mixed into the coolant. If these solid particles are not filtered out in time, it will have a negative impact on the quality of the coolant and the cutting effect.

[0003] At present, the existing filtering devices on the market have a problem when in use due to their single structure. During the filtration process, the accumulated solids are prone to clogging on the filter net, thus affecting the filtration effect. In addition, the coolant input by the existing filtering devices is mostly discharged directly onto the filter net. The fixed objects mixed in the coolant will cause impact on the filter net. Long-term impact will easily cause damage to the filter net, affecting its service life.

[0004] Based on this, the utility model designs a solid matter filtering device to solve the above problems. Utility Model Content

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides the following technical solutions: a solid matter filtering device, comprising a filter box 1, a base 2, a vibration motor 3, a shock-absorbing spring 4, a machine base 5, a coarse filter screen plate 6, a fine filter screen plate 7, a locking mechanism 8, a fixing frame 9, a buffer bucket 10, a box cover 11, a liquid inlet 12 and a liquid outlet 13, the bottom end of the filter box 1 is fixedly connected with the base 2, the center of the bottom end of the base 2 is fixedly installed with the vibration motor 3, a plurality of shock-absorbing springs 4 are annularly arranged at the bottom end of the base 2, and the lower ends of the plurality of shock-absorbing springs 4 are fixedly connected with the machine base 5, and two groups of card-connecting rails 101 are symmetrically arranged inside the filter box 1, and the coarse filter screen plate 6 and the fine filter screen plate 7 are respectively card-connected and fixed in the two groups of card-connecting rails 101.

[0027] A first silicone strip 601 is provided on the front of the coarse filter screen 6, and the first silicone strip 601 is arranged in a corresponding groove opened on the front of the filter box 1. A second silicone strip 701 is provided on the front of the fine filter screen 7, and the second silicone strip 701 is arranged in a corresponding groove opened on the front of the filter box 1. Two groups of guide grooves 102 are symmetrically opened on the front of the filter box 1, and installation grooves 103 are opened in the guide grooves 102, and locking mechanisms 8 are provided in the installation grooves 103.

[0028] The locking mechanism 8 includes a pull rod 801, a connecting rod 802, a fixed seat 803, a block 804 and an elastic spring 805. The two ends of the pull rod 801 are fixedly connected with connecting rods 802, which are slidably arranged in corresponding guide grooves 102. The two connecting rods 802 are respectively connected to the two fixed seats 803.

[0029] The two fixing seats 803 are fixedly connected to the two stoppers 804 , respectively. The upper ends of the two stoppers 804 are fixedly connected to the corresponding installation slots 103 via two elastic springs 805 .

[0030] Through the above structure, the filter box 1 can be vibrated up and down as a whole under the action of the vibration motor 3, so that the coarse filter screen plate 6 and the fine filter screen plate 7 in the filter box 1 can vibrate. Under the action of the up and down vibration, the solid matter filtered on the coarse filter screen plate 6 and the fine filter screen plate 7 can be vibrated to avoid clogging of the mesh holes, and at the same time, the filtered matter can be spread flat on the screen to avoid the problem of accumulation. The structural design in which the coarse filter screen plate 6 and the fine filter screen plate 7 are fixed to the filter box 1 by the locking mechanism 8 is convenient for the installation and disassembly of the coarse filter screen plate 6 and the fine filter screen plate 7, and for the cleaning of the solid filtered matter.

[0031] Please refer to Figure 2 , Figure 3 and Figure 6 A fixing frame 9 is fixedly connected to the four inner walls of the filter box 1, and a buffer bucket 10 is connected to the four fixing frames 9. The buffer bucket 10 includes a bucket body 1001, a liquid outlet groove 1002, a bottom plate 1003, a buffer spring 1004 and an impact plate 1005. A plurality of liquid outlet grooves 1002 are annularly opened on the wall of the bucket body 1001.

[0032] A bottom plate 1003 is provided at the bottom of the bucket body 1001 . Four buffer springs 1004 are provided in a ring shape on the upper end of the bottom plate 1003 . The upper ends of the four buffer springs 1004 are all connected to the impact plate 1005 .

[0033] A box cover 11 is fixedly mounted on the uppermost end of the filter box 1 , a liquid inlet 12 is arranged at the center of the box cover 11 , and a liquid outlet 13 is opened on the right side of the bottom end of the filter box 1 .

[0035] Through the structure of the buffer bucket 10, the coolant input into the filter box 1 can be buffered to prevent the coolant from directly impacting the filter screen plate, thereby playing a buffering and protective role for the filter screen plate.

[0036] The working principle and use process of the utility model are as follows: when in use, the vibration motor 3 is started, and the vibration generated by the vibration motor 3 makes the filter box 1 vibrate as a whole, so that the coarse filter screen plate 6 and the fine filter screen plate 7 vibrate, and then the coolant is transported into the filter box 1 through the liquid inlet 12, and the coolant transported through the liquid inlet 12 will first impact with the impact plate 1005, and the impact of the coolant is buffered by the impact plate 1005 and the buffer spring 1004, so that the flow rate of the coolant is reduced, and then the coolant falls onto the coarse filter screen plate 6 through the multiple liquid outlet grooves 1002 opened on the bucket body 1001, and the coolant is filtered once by the coarse filter screen plate 6 to filter out larger particles of solid matter, and the filtered coolant falls onto the fine filter screen plate 7 for secondary filtration to filter the coolant. Small and medium-sized solid particles are filtered out to ensure the filtering effect. During the filtering, due to the effect of vibration, the coolant and solids can be vibrated to avoid clogging of the filter mesh holes. At the same time, the filtered matter can be spread flat on the mesh plate to avoid accumulation. The filtered coolant can be discharged through the liquid outlet 13. When it is necessary to clean the filtered matter on the coarse filter mesh plate 6 and the fine filter mesh plate 7, it is only necessary to pull the corresponding pull rod 801 upwards, so that the two connecting rods 802 slide upwards in the guide groove 102, and the two blocks 804 slide upwards into the installation groove 103 until the blocks 804 are separated from the limit of the mesh plate. The mesh plate can be pulled out to clean the filtered matter, and the pull rod 801 is released. Under the action of the elastic spring 805, the blocks 804 are reset, which is convenient for regular cleaning of accumulated solids.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
