[0023] In an exemplary embodiment, Figure 1 、 2As shown, this embodiment provides a glass grinding waste liquid filtration and treatment system, which includes an outer shell 1, the outer shell 1 is provided with an inner filter tank 2 located therein and an outer filter tank 3 located directly above the inner filter tank 2, and a plurality of filter rods 4 that are vertically detachable and extend through the outer filter tank 3 to the inner filter tank 2, a plurality of first filter holes are provided at the bottom of the inner filter tank 2, a channel 5 extending from the outer filter tank 3 to the inner filter tank 2 is provided in the filter rod 4, and a plurality of second filter holes and a plurality of third filter holes are provided on the filter rod 4, which are respectively located in the inner filter tank 2 and the outer filter tank 3 and are respectively connected to the channel 5, and the upper end of the filter rod 4 is also detachably connected to an end head 6 for opening and closing the top of the channel 5. In this solution, the waste liquid to be treated is directly added to the outer filter tank 3, and then enters the channel 5 through the second filter hole on the filter rod 4, and then enters the inner filter tank 2 below from the channel 5 through the third filter hole, and finally passes through the first filter hole to the bottom of the outer shell 1 to realize overall filtration. When cleaning is required during the process, most of the impurities will be intercepted in the outer filter tank 3, which can be easily cleaned without having to stop the machine for cleaning, thereby improving the overall efficiency and solving the problem that the overall processing efficiency cannot be improved due to the need for more frequent shutdowns for cleaning in the prior art; furthermore, an annular support platform is provided on the inner wall of the outer filter tank 3, and a top groove 7 is provided on the support platform, and a plurality of sleeves 8 corresponding to a plurality of filter rods 4 are fixedly connected to the bottom of the top groove 7, and the inner diameter of the sleeve 8 is larger than the outer diameter of the filter rod 4, and a plurality of fourth filter holes are provided on the sleeve 8 and the bottom of the top groove 7. The provided top groove 7 plays the role of the first filtration, and most of the impurities are removed. The impurities in the top groove 7 are intercepted by the fourth filter hole, and the waste liquid passes through the fourth filter hole and then enters the channel 5 through the second filter hole on the filter rod 4. In this way, when cleaning, most of the impurities can be cleaned by directly taking out the top groove 7, and the waste liquid still needs to be intercepted by the second filter hole during the removal process, which will not cause adverse effects. In more detail, there is also a fourth filter hole on the sleeve 8, and there is also a second filter hole on the filter rod 4 located in the sleeve 8. In this way, when more waste liquid is added, there is more filtering area to cooperate, so as to achieve efficient filtration treatment, and the outer diameter of the filter rod 4 is smaller, so that the top groove 7 can be installed and removed without affecting the stability of the filter rod 4, so that the first cleaning does not affect the normal progress of the overall filtration treatment; in a further solution, an elastic sleeve 9 is also fixedly sleeved on the end head 6, and the elastic sleeve 9 is elastically pressed against the inner wall of the sleeve 8 to seal them.

[0024] like Figure 1As shown, the outer shell 1 is also fixedly connected to a balance pipe, which includes an upper pipe section 10 located outside the outer shell 1 and a first lower pipe section 11 located inside the outer shell 1. The first lower pipe section 11 is connected to the space below the inner filter tank 2 of the outer shell 1. The upper pipe section 10 extends upward. The provided balance pipe serves to balance the air pressure inside and outside the outer shell 1 so that the filtration process can proceed smoothly. In more detail, the lower end of the upper pipe section 10 is also fixedly connected to a second lower pipe section 12 located outside the outer shell 1 and extending downward. A valve 13 is provided on the second lower pipe section 12. The upper pipe section 10 is arranged to face upward and the second lower pipe section 12 is arranged to face downward. When the liquid in the outer shell 1 After the liquid enters the upper pipe section 10 (entering the upper pipe section 10 also enters the second lower pipe section 12, which can be viewed from the top of the upper pipe section 10, or the upper pipe section 10 or the second lower pipe section 12 can be set to a transparent material for easy observation), the valve 13 can be opened to quickly drain the liquid. A drain pipe 14 is also provided at the bottom of the outer shell 1, which can also provide a drainage path for the liquid. The reason for setting the balance pipe is to filter first to load more liquid into the outer shell 1, and then uniformly drain it. This can make the system have better and more convenient mobility, that is, it can be moved more conveniently between various workstations.

[0025] like Figure 1 、 2 As shown, in a further solution, the bottom of the outer filter tank 3 is fixedly connected with a plurality of connecting sleeves 15 corresponding to the plurality of filter rods 4 one by one, and a first external thread section is provided on the outer wall of the middle section of the filter rod 4, and a first internal thread section cooperating with the first external thread section is provided on the inner wall of the connecting sleeve 15, and the lower end of the filter rod 4 can pass through the connecting sleeve 15, and the connecting sleeve 15 and the filter rod 4 are threadedly connected, so that they are relatively fixed as a whole, and the filter rod 4 can be relatively stable during the process of removing the top tank 7, and the channel 5 passes through the middle of the first external thread section, so that the liquid passes through the connecting sleeve 15 smoothly to the inner filter tank 2 below, and the lower end of the filter rod 4 is smaller to avoid excessive collision with the first internal thread section when installing the filter rod 4, thereby avoiding damage to the first internal thread section. In addition, the bottom of the inner filter tank 2 is also fixedly connected with a plurality of top heads 16 corresponding to the plurality of filter rods 4 one by one. The lower end surface of the filter rod 4 is recessed and provided with a groove for the top head 16 to be inserted. The lower end of the filter rod 4 passes through the groove provided on the rear end surface of the connecting sleeve 15 and docks with the top head 16. At this time, the first internal thread section and the first external thread section are also just matched and connected, so that the filter rod 4 is installed; in further detail, a second internal thread section is provided on the inner wall of the upper end of the channel 5, and the lower end of the end head 6 is fixedly connected with a connecting head, and a second external thread section matching the second internal thread section is provided on the connecting head. The setting of the connecting head enables the end head 6 to be connected to the channel 5. At the same time, the set end heads 6 are all located in the sleeve 8, so the top groove 7 must be removed first before the filter rod 4 can be disassembled.

[0026] like Figure 1 、 2 As shown in FIG3 , further, a first support ring 17 is fixedly provided on the upper end of the outer shell 1, and a bottom ring 18 is fixedly connected to the lower end of the outer filter tank 3. The bottom ring 18 is against the first support ring 17 and all the connecting sleeves 15 are located in the first support ring 17. The bottom ring 18 and the first support ring 17 are also locked by bolts to achieve a detachable connection. Furthermore, a second support ring 19 is fixedly provided in the outer shell, and a support ring 20 is fixedly connected to the upper end of the inner filter tank 2. The support ring 20 is placed on the second support ring 19. Due to the setting of the head 16 and the groove (the head 16 can be an arc-shaped upper The filter rod 4 is convex in shape, and the groove is correspondingly arc-shaped. In this way, when the filter rod 4 is installed, the filter rod 4 is rotated downward so that the lower end of the filter rod 4 moves downward, so that the top head 16 can be better accommodated in the corresponding groove, and the positioning is achieved to lock the relative position between the filter rod 4 and the inner filter tank 2). The support ring 20 and the second support ring 19 do not need to be tightened with bolts like the first support ring 17 and the bottom ring 18 to achieve relative fixation. The second support ring 19 is smaller than the first support ring 17, so that the inner filter tank 2 can be smoothly taken out, so as to facilitate the subsequent thorough cleaning of the internal structural components.
