Description

Technical Field

[0001] This utility model relates to the field of diethylene glycol monoethylene diether production technology, and specifically discloses a waste recycling device for diethylene glycol monoethylene diether production. Background Technology

[0002] In the industrial production of diethylene glycol monoethylene diether, the post-reaction waste mainly includes unreacted raw materials, by-product polymers (particle size 10-500 μm), solid catalyst particles (particle size 50-200 μm), and mechanical impurities (iron filings, sealing packing debris, etc.). To achieve catalyst reuse, improve product purity (requiring impurity content in liquid phase recovery to be <0.5%), and meet environmental emission standards, gradient solid-liquid separation of the waste is required. The key challenge lies in the efficient retention of micron-sized particles in high-viscosity media (dynamic viscosity 3000-6000 mPa·s) and the rapid cleaning of filter residue.

[0003] Traditional filtration technologies have significant limitations: when fixed vibrating screens process high-viscosity waste, the screen holes become clogged at a high rate, requiring frequent shutdowns for cleaning; although centrifugal separation equipment can separate solid impurities and particles, the filter residue adhering to the inner wall of the filter cartridge requires manual disassembly and cleaning, which is time-consuming, labor-intensive, and reduces work efficiency. Utility Model Content

The device is convenient to discharge, highly automated, and improves work efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-3 A waste recycling device for the production of diethylene glycol monoethylene diether includes:

[0025] Outer cylinder 1 is a cylindrical body with a conical bottom. The top and bottom of the outer cylinder 1 are respectively provided with a feed inlet 2 and a discharge outlet 3.

[0026] The primary filtration mechanism includes a primary filter screen 4 installed inside the upper part of the outer cylinder 1. Support plates 6 are fixedly connected to both sides of the upper part of the inner wall of the outer cylinder 1 by spring seats 5. The primary filter screen 4 is set between the two support plates 6. The primary filter screen 4 has a funnel-shaped structure. Vibration motors 7 are installed on the lower end faces of the two support plates 6.

[0027] The secondary filtration mechanism includes a connecting cylinder 8 installed inside the lower part of the outer cylinder 1. The bottom of the connecting cylinder 8 is rotatably connected to a bracket 24 via a rotating rod 10. The top of the bracket 24 is fixedly connected to a separating filter cylinder 11. The connecting cylinder 8 is rotatably connected to the outer cylinder 1 via a horizontally set rotating shaft 9. Both sides of the bottom of the connecting cylinder 8 are provided with material leakage ports 20.

[0028] In this embodiment: the outer cylinder 1 is a cylindrical structure with a conical bottom. High-viscosity waste is injected into the top feed port 2, and the slag is discharged through the cone bottom discharge port 3. The funnel-shaped primary filter screen 4 generates high-frequency vibration through the vibration motor 7 on the two side support plates 6, which intercepts large particles of impurities and effectively avoids clogging of the primary filter screen 4, eliminating the need for repeated shutdowns for cleaning. The waste after preliminary filtration enters the interior of the separation filter cylinder 11 under the guidance of the two guide plates 17. The guide plates 17 are inclined and coated with an anti-stick coating to prevent sticking. The separation filter cylinder 11 is driven to rotate at high speed by the rotating rod 10. Centrifugal force causes the liquid to penetrate the filter holes of the separation filter cylinder 11, and the solid slag adheres to the inner wall. The connecting cylinder 8 rotates 180° through the rotating shaft 9. With the help of the bottom scraper 26 and the side wall scraper 27 inside the separation filter cylinder 11, the waste adhering to the inner wall of the separation filter cylinder 11 is scraped off, thereby using gravity to discharge the slag. The discharge is convenient, the degree of automation is high, and the work efficiency is improved.

[0029] As a technical optimization of this utility model, a first motor 12 is installed at the bottom of the connecting cylinder 8. The output end of the first motor 12 is fixedly connected to the rotating rod 10. One end of the rotating shaft 9 extends to the outside of the outer cylinder 1 and is fixedly connected to the driven gear 13. An mounting plate 14 is fixedly connected to the outer wall of the outer cylinder 1. A second motor 15 is installed on the upper surface of the mounting plate 14. The output end of the second motor 15 is fixedly connected to the driving gear 16 that meshes with the driven gear 13. A third motor 25 is installed on the upper surface of the bracket 24. The output end of the third motor 25 extends to the inside of the separating filter cylinder 11 and is fixedly connected to a horizontally arranged bottom scraper 26. Side wall scrapers 27 are fixedly connected to both the left and right sides of the upper surface of the bottom scraper 26.

[0030] In this embodiment: the driving gear 16 meshes with the driven gear 13 to precisely control the flipping angle of the connecting cylinder 8, the first motor 12 drives the separating filter cylinder 11 to rotate, and the second motor 15 controls the flipping.

[0031] As a technical optimization of this utility model, two symmetrical and inclined guide plates 17 are fixedly connected to the inner wall of the outer cylinder 1. The two guide plates 17 are located between the primary filter screen 4 and the separation filter screen cylinder 11. The outer wall of the guide plate 17 is coated with a polytetrafluoroethylene anti-stick coating.

[0032] In this embodiment: the polytetrafluoroethylene coating of the guide plate 17 reduces the amount of high-viscosity liquid adhering, the tilt angle optimizes the fluid path, and shortens the filtration time.

[0033] As a technical optimization of this utility model, two rollers 18 are installed at the bottom of the separating filter cylinder 11. Both rollers 18 are rolledly connected to the bottom of the inner end of the connecting cylinder 8. A shock absorber 19 is provided between the rollers 18 and the separating filter cylinder 11.

[0034] In this embodiment, the roller 18 has a low coefficient of rolling friction. When the separating filter cylinder 11 rotates, the roller 18 rolls with the bottom of the inside of the separating filter cylinder 11, which improves the stability of the separating filter cylinder 11.

[0035] As a technical optimization of this utility model, both ends of the primary filter screen 4 are detachably connected by fixing bolts 21 and support plate 6.

[0036] In this embodiment, both ends of the primary filter screen 4 are detachably connected to the support plate 6 via fixing bolts 21, which facilitates replacement and cleaning.

[0037] As a technical optimization of this utility model, a sealing door 22 is provided on the upper part of the outer wall of the outer cylinder 1, and a transparent observation window 23 is provided on the lower part of the outer wall of the outer cylinder 1.

[0038] In this embodiment: a sealing door 22 is provided on the upper part of the outer wall of the outer cylinder 1 to facilitate the replacement and cleaning of the primary filter screen 4, and a transparent observation window 23 to facilitate the observation of the internal condition of the outer cylinder 1.

[0039] As a technical optimization of this utility model, the vibration motor 7, the first motor 12, the second motor 15 and the third motor 25 are all electrically connected to the external control system.

[0040] In this embodiment, the vibration motor 7, the first motor 12, and the second motor 15 are controlled by an external control system.

[0041] The working principle and usage process of this utility model are as follows: During use, waste material enters the outer cylinder 1 through the feed inlet 2 and is screened by the vibrating screen 4 of the funnel-shaped primary filter. Large particles of impurities are retained on the surface of the primary filter screen 4. The vibration motor 7 is started to drive the primary filter screen 4 to vibrate, which improves the filtration effect and reduces the clogging rate. The waste material after preliminary filtration enters the interior of the separation filter cylinder 11 under the guidance of two guide plates 17. The guide plates 17 are inclined and coated with an anti-stick coating to prevent sticking. The separation filter cylinder 11 is driven by the rotating rod 10 to rotate at high speed. The centrifugal force causes the liquid to penetrate the filter holes of the separation filter cylinder 11, while the solid residue adheres to the inner wall. When the second motor 15 is started, it drives the drive gear 16 to rotate, which in turn drives the driven gear 13 to rotate. The driven gear 13 further drives the rotating shaft 9 to rotate, thereby causing the connecting cylinder 8 to rotate 180° through the rotating shaft 9. The third motor 25 is then started to drive the bottom scraper 26 and the side wall scraper 27 to rotate, scraping off the waste material adhering to the inner wall of the separation filter cylinder 11. The residue is then discharged by gravity, making discharge convenient.
