Abstract
Description
Technical Field
[0001] This utility model relates to the field of methyl acetal technology, and in particular to a recycling line for methyl acetal production waste. Background Technology
[0002] Methyl acetal is a colorless and transparent liquid with a chloroform-like odor. It has excellent physical and chemical properties, namely good solubility, low boiling point, and good water miscibility. It can be widely used in cosmetics, pharmaceuticals, household products, industrial automotive products, pesticides, leather polishes, rubber industry products, paints, inks and other products.
[0003] Waste is generated during the production of methyl acetal, so it is necessary to recycle the waste. The waste from methyl acetal production may contain some larger particles. If these particles enter the distillation vessel, they will settle at the bottom of the vessel or on the heating pipe wall, which is not conducive to the normal operation of the recycling line.

A filter tube is installed at the front end of the distillation kettle in the main body of the methyl acetal production waste recycling line. Two filter screen frames are installed inside the filter tube. Filter screen one and filter screen two are installed in the two filter screen frames respectively. The two filter screen frames are connected by two connecting rods. A limit block is provided on the outside of the connecting rods. A limit hole is opened on the limit block.
[0007] Slots are provided on both sides of the inner wall of the filter tube, and an annular groove is provided on the inner wall of the filter tube. The annular groove is connected to the slot. Grooves are provided at both ends of the bottom of the annular groove. A spring is fixedly installed at the bottom of the groove, and a limiting post is fixedly installed at the top of the spring. The top of the limiting post is spherical and is inserted into the limiting hole.
[0008] Furthermore, in a preferred configuration, grooves are provided on both sides of the inner wall of the groove.
[0009] In addition, a preferred structure is that both ends of the bottom of the limiting post are provided with sliders, which slide within the groove.
[0010] In addition, a preferred structure is that the filter frame is provided with a pressure ring, and the filter frame is provided with slots on all four sides, with threaded holes at the bottom of the slots.
[0011] In addition, a preferred structure is that the pressure ring is provided with a locking block on all four sides, the locking block is locked into the locking groove, and a bolt passes through the locking block and is threaded into the threaded hole.
[0012] Furthermore, in a preferred configuration, an operating lever is fixedly mounted on the top of one of the two filter frames.
[0013] The beneficial effects of this utility model are as follows:
[0014] In this invention, particulate matter in the methyl acetal production waste is intercepted by filter screen one and filter screen two, preventing larger particles from entering the distillation kettle, which is beneficial to the normal operation of the recycling line and thus facilitates the recycling of methyl acetal production waste.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-9 A recycling line for methyl acetal production waste includes a main body 1 of the methyl acetal production waste recycling line. A filter tube 2 is installed at the front end of the distillation kettle in the main body 1 of the methyl acetal production waste recycling line. Two filter screen frames 3 are installed inside the filter tube 2. Filter screen 1 5 and filter screen 2 6 are installed in the two filter screen frames 3 respectively. The two filter screen frames 3 are connected by two connecting rods 4. A limit block 41 is provided on the outside of the connecting rod 4. A limit hole 411 is opened on the limit block 41.
[0027] The filter tube 2 has slots 21 on both sides of its inner wall and an annular groove 22 on its inner wall. The annular groove 22 is connected to the slot 21. The bottom of the annular groove 22 has grooves 23 at both ends. A spring 10 is fixedly installed at the bottom of the groove 23. A limiting post 11 is fixedly installed at the top of the spring 10. The top of the limiting post 11 is spherical and is inserted into the limiting hole 411.
[0028] Meanwhile, grooves 231 are provided on both sides of the inner wall of the groove 23.
[0029] Furthermore, sliders 111 are provided at both ends of the bottom of the limiting post 11. The sliders 111 slide within the groove 231, making the movement of the limiting post 11 more stable.
[0030] Meanwhile, a pressure ring 8 is provided on the filter frame 3, and slots 31 are provided on all four sides of the filter frame 3, with threaded holes 311 at the bottom of the slots 31.
[0031] Meanwhile, the pressure ring 8 is provided with a locking block 81 on all four sides. The locking block 81 is locked into the locking groove 31. The bolt 9 passes through the locking block 81 and is threaded into the threaded hole 311, so that the pressure ring 8 is installed on the filter screen frame 3, and the filter screen 1 5 and filter screen 2 6 are pressed tightly.
[0032] Furthermore, an operating lever 7 is fixedly installed on the top of one of the two filter frames 3, which facilitates the removal of both filter frames 3.
[0033] In this embodiment, the methyl acetal production waste enters the distillation kettle through filter screen 5 and filter screen 6 in the filter tube 2, while the larger particles that are ultimately mixed into the methyl acetal production waste are intercepted by the filter screen 5 and filter screen 6, which is beneficial to the normal operation of the recycling line.
[0034] To remove filter tube 2, clean or replace filter screens 5 and 6. Remove filter tube 2 from the top of the delivery pipe. Then, rotate the operating lever 7 90 degrees. At this time, the limiting post 11 is squeezed into the groove 23, and the spring 10 is compressed. When the limiting block 41 rotates to the bottom of the slot 21 within the annular groove 22, pull the operating lever 7 upwards. The limiting block 41 will slide upwards within the slot 21, allowing the two filter screen frames 3 to be removed. Filter screens 5 and 6 can then be cleaned. If filter screens 5 and 6 need to be replaced, loosen bolt 9 and remove bolt 9 from the threaded hole 3. Remove the two pressure rings 8 from the two filter screen frames 3 to replace filter screen 1 5 and filter screen 2 6. Then, insert the bolt 9 through the clip 81 and into the threaded hole 311. The pressure rings 8 will press filter screen 1 5 and filter screen 2 6 tightly. Next, align the limiting block 41 with the slot 21 and insert it. Then, rotate the operating lever 7 90 degrees. The limiting block 41 will squeeze the limiting post 11 into the groove 23. Then, the limiting post 11 will be ejected into the limiting hole 411 under the elastic action of the spring 10, completing the replacement of filter screen 1 5 and filter screen 2 6. Then, install the filter tube 2 onto the conveying pipe.
[0035] In this invention, particulate matter in the methyl acetal production waste is intercepted by filter screen 5 and filter screen 6, preventing larger particles from entering the distillation kettle, which is beneficial to the normal operation of the recycling line and thus facilitates the recycling of methyl acetal production waste.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
