Description

Technical Field

[0001] This utility model relates to the field of titanium-silicon molecular sieve production technology, and in particular to a device for recycling washing wastewater from titanium-silicon molecular sieve production. Background Technology

[0002] In the production of titanium-silicon molecular sieves, washing is a crucial post-processing step, designed to remove impurities such as template agents and salts adhering to the surface of the molecular sieve crystals to obtain a final product with high purity and high catalytic activity. This process generates a large amount of washing wastewater containing suspended solids, mainly ultrafine molecular sieve powder.

[0003] Currently, the conventional recycling and treatment methods for this type of washing wastewater mostly adopt the static sedimentation method to achieve material recovery; Because the particles of titanium silicon molecular sieves are extremely fine, their settling speed in water is slow. Complete solid-liquid separation often takes several hours or even tens of hours, which severely restricts the production rhythm and cannot be effectively matched with continuous production lines. At the same time, in order to achieve large-scale processing, it is necessary to build a huge sedimentation tank, which occupies a large area. Moreover, relying solely on gravity sedimentation, some fine particles may remain in a suspended state for a long time, making it difficult to settle completely and reducing the recovery effect. Utility Model Content

[0004] In view of the problem that the existing static sedimentation process takes a long time and seriously restricts the production pace, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a wastewater recovery device for the production of titanium silicon molecular sieves, which aims to continuously recover wastewater, improve recovery efficiency, and increase the recovery rate of materials.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a wastewater recycling device for washing in the production of titanium silicon molecular sieves, including a recycling bin with a notch, a rotating platform rotatably installed at the center of the recycling bin, and screen cylinders rotatably installed on both sides of the top of the rotating platform, with filter bags detachably installed inside the screen cylinders. A linear motor is installed inside the recovery chamber on the side away from the notch. A splash guard for covering the screen cylinder is installed on the movable end of the linear motor. An injection pipe is fixed to the top of the splash guard by a pipe rack. A drive assembly for driving the screen cylinder to rotate is installed inside the recovery chamber on the side close to the linear motor, and the drive assembly is detachably connected to the screen cylinder.

[0007] As an improved technical solution, a pad column is installed at the center of the inside of the recycling bin, and a servo motor for driving the rotating table is installed at the top of the pad column. Support columns are installed on both sides of the bottom of the rotating table, and a roller that rolls inside the recycling bin is installed at the end of the support column away from the rotating table.

[0008] As an improved technical solution, a rotating column is welded to the center of the bottom of the screen cylinder, and round holes are opened on both sides of the top of the rotating platform for the rotating column to pass through. The rotating column is rotatably installed inside the round holes through bearings, and a ring of universal ball bearings is fixed at the bottom of the screen cylinder.

[0009] As an improved technical solution, the drive assembly is installed inside the recycling bin via a pad block on an electric telescopic rod. The movable end of the electric telescopic rod is fixedly connected to a drive motor, and the drive end of the drive motor is fixedly connected to a cross-shaped locking block. A cross-shaped locking slot for locking the cross-shaped locking block is provided at the center of the end of the rotating column away from the screen cylinder.

[0010] As an improved technical solution, the drive assembly also includes a water-proof cover fixed inside the recycling bin, and the electric telescopic rod is located in the inner cavity of the water-proof cover.

[0011] As an improved technical solution, a pressure ring is detachably installed at the top of the screen cylinder, and an annular groove is provided at one end of the pressure ring near the screen cylinder.

[0012] As an improved technical solution, the end of the screen cylinder near the pressure ring is welded with four first threaded hole blocks at equal intervals in an annular shape, and the end of the pressure ring near the screen cylinder is welded with four second threaded hole blocks at equal intervals in an annular shape. The first threaded hole blocks and the second threaded hole blocks correspond one-to-one, and hexagonal bolts are threaded between the first threaded hole blocks and the second threaded hole blocks.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. This utility model uses a pressure ring to press the filter bag onto the top of the screen cylinder, firmly fixing the filter bag inside the screen cylinder to prevent it from shifting and ensuring continuous filtration of wastewater. Furthermore, the pressure ring is detachably installed on the top of the screen cylinder using hexagonal bolts, facilitating the installation and removal of the filter bag.

[0014] 2. In this utility model, two screen cylinders are provided at both ends of the rotating table. The positions of the two screen cylinders can be interchanged by a servo motor, which reduces the downtime of the device caused by filter bag replacement, improves the utilization rate of the device, and further improves the filtration efficiency of the device.

[0015] 3. This utility model generates a powerful centrifugal force through high-speed rotation, which can forcibly separate solid particles in wastewater in a very short time and trap them in the filter bag. This avoids the inherent defects of the time-consuming static sedimentation method, and the separation efficiency is improved by orders of magnitude. Furthermore, the powerful centrifugal force ensures the effective separation of extremely fine particles. The solids collected by the filter bag have low water content and high purity, making them easy to recycle as valuable products and improving economic benefits. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figures 1-4This is the first embodiment of the present invention, which provides a wastewater recycling device for the production of titanium silicon molecular sieves. This wastewater recycling device for the production of titanium silicon molecular sieves includes a recycling chamber 1 with a notch, a drainage hole at the bottom of the recycling chamber 1, a pad at the bottom of the recycling chamber 1, a rotating platform 5 rotatably installed at the center of the inside of the recycling chamber 1, and a screen cylinder 7 rotatably installed on both sides of the top of the rotating platform 5. A filter bag 14 is detachably installed inside the screen cylinder 7. A linear motor 2 is installed inside the recovery chamber 1 on the side away from the notch. A splash guard 3 is installed on the movable end of the linear motor 2 to cover the screen cylinder 7. When the wastewater is filtered through the screen cylinder 7, the linear motor 2 drives the splash guard 3 to move towards the screen cylinder 7, completely covering the screen cylinder 7 and blocking the splashed wastewater to prevent it from splashing, thus improving the cleanliness of the environment and preventing it from polluting the environment. The top of the splash guard 3 is fixed with an injection pipe 4 by a pipe rack, and the outlet end of the injection pipe 4 is angled towards the screen cylinder 7. A drive assembly 6 for driving the screen cylinder 7 to rotate is installed inside the recovery chamber 1 on the side close to the linear motor 2, and the drive assembly 6 is detachably connected to the screen cylinder 7.

[0023] A support column is installed at the center of the inside of the recovery chamber 1. A servo motor 8 is installed at the top of the support column to drive the rotating table 5 to rotate. The drive end of the servo motor 8 is connected to the bottom of the rotating table 5. Two screen cylinders 7 are set at both ends of the rotating table 5. The positions of the two screen cylinders 7 can be interchanged by the servo motor 8 to reduce the downtime caused by the replacement of filter bags 14, improve the utilization rate of the device, and further improve the filtration efficiency of the device. Support columns 9 are installed on both sides of the bottom of the rotating table 5. Rollers that roll inside the recovery chamber 1 are installed at the ends of the support columns 9 away from the rotating table 5. The support columns 9 and the rollers installed at their bottoms provide support for the rotating table 5, improve the stability of the rotating table 5 when supporting the screen cylinders 7, and extend the stability and service life of the device.

[0024] A rotating column 12 is welded to the center of the bottom of the screen cylinder 7. The rotating platform 5 has round holes on both sides of the top for the rotating column 12 to pass through. The rotating column 12 is rotatably installed inside the round hole through a bearing. A ring of universal ball bearings 11 is fixed at the bottom of the screen cylinder 7, and the rolling end of the universal ball bearings 11 rolls on the upper surface of the rotating platform 5.

[0025] The drive assembly 6 is installed inside the recycling bin 1 via a pad block on the electric telescopic rod 62. The movable end of the electric telescopic rod 62 is fixedly connected to the drive motor 63. The drive end of the drive motor 63 is fixedly connected to the cross-shaped locking block 64. A cross-shaped locking groove for locking the cross-shaped locking block 64 is opened at the center of the end of the rotating column 12 away from the screen cylinder 7.

[0026] The drive assembly 6 also includes a water-proof cover 61 fixed inside the recycling bin 1, and the electric telescopic rod 62 is located in the inner cavity of the water-proof cover 61.

[0027] During use, the high-speed rotation generates a powerful centrifugal force, which can forcibly separate solid particles in wastewater in a very short time and trap them in the filter bag 14. This avoids the inherent drawback of the time-consuming static sedimentation method, and the separation efficiency is improved by orders of magnitude. Furthermore, the powerful centrifugal force ensures the effective separation of extremely fine particles. The solids collected by the filter bag 14 have low water content and high purity, making them easy to recycle as valuable products and improving economic benefits.

[0028] Example 2 Reference Figures 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a pressure ring 10 is detachably installed at the top of the sieve cylinder 7, and an annular groove is provided at one end of the pressure ring 10 near the sieve cylinder 7.

[0029] Four first threaded hole blocks 13 are welded in an annular shape at equal intervals at one end of the screen cylinder 7 near the pressure ring 10. Four second threaded hole blocks 15 are welded in an annular shape at equal intervals at one end of the pressure ring 10 near the screen cylinder 7. The first threaded hole blocks 13 and the second threaded hole blocks 15 correspond one-to-one. Hexagonal bolts 16 are threaded between the corresponding first threaded hole blocks 13 and second threaded hole blocks 15. The pressure ring 10 presses the filter bag 14 to the top of the screen cylinder 7, firmly fixing the filter bag 14 inside the screen cylinder 7 to prevent it from shifting and to ensure that the filter bag 14 continuously filters the wastewater. In addition, the pressure ring 10 is detachably installed at the top of the screen cylinder 7 by the hexagonal bolts 16, which facilitates the installation and removal of the filter bag 14.

[0030] During use, the process of installing the filter bag 14 inside the screen cylinder 7 is as follows: the filter bag 14 is placed inside the screen cylinder 7, the top of the filter bag 14 is bent and fastened to the top of the screen cylinder 7, and then the pressure ring 10 is pressed inside the screen cylinder 7, pressing the filter bag 14 and the top of the screen cylinder 7 into the annular groove at the bottom of the pressure ring 10. Then, the first threaded hole block 13 and the second threaded hole block 15 are aligned one by one, and then the corresponding first threaded hole block 13 and second threaded hole block 15 are fixed together by hexagonal bolts 16, so that the pressure ring 10 can be detachably installed at the top of the screen cylinder 7.

[0031] The remaining structure is the same as that in Example 1.

[0032] Based on embodiments 1-2, the working principle of this utility model is as follows: the servo motor 8 drives the rotating table 5 to rotate, moving the sieve cylinder 7 to the filtration point. Then the servo motor 8 stops, keeping the sieve cylinder 7 stationary at the filtration point. The electric telescopic rod 62 extends to drive the cross-shaped locking block 64 into the cross-shaped locking groove at the bottom of the rotating column 12. The electric telescopic rod 62 shortens to release the cross-shaped locking block 64 from the cross-shaped locking groove, thus completing the detachable connection between the drive motor 63 and the screen cylinder 7, which facilitates the interchange of the positions of the two screen cylinders 7. The drive motor 63 drives the cross-shaped clamping block 64 to rotate at high speed, which in turn drives the screen cylinder 7 to rotate at high speed. At the same time, wastewater is injected into the bottom of the screen cylinder 7 through the injection pipe 4, and the wastewater is sprayed onto the filter bag 14. The material in the wastewater is filtered by the filter bag 14 and stored inside the filter bag 14. The liquid falls into the interior of the recovery chamber 1 through the screen cylinder 7, realizing solid-liquid separation in the wastewater. This facilitates continuous separation of wastewater. At the same time, the centrifugal stacked filter bags 14 filter the wastewater, which improves the filtration rate and the retention rate of the material in the wastewater.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
