Description

Technical Field

[0001] This utility model relates to the field of salt production and salt chemical technology, and in particular to a high nitrate brine recovery device. Background Technology

[0002] High-nitrate brine is a common byproduct of industrial production, and its direct discharge can cause serious pollution to aquatic environments. Therefore, effective recovery and treatment of high-nitrate brine is crucial, and high-nitrate brine recovery devices have been widely used in this context. In the recovery and treatment process, filtration is a key pretreatment step for removing suspended solids and impurities from the water, directly affecting the effectiveness of subsequent advanced treatment.

[0003] The core component for filtration is the filter screen, which separates solid pollutants from water through physical interception. As the system continues to operate, a large amount of impurities are trapped on the filter screen's surface, causing it to gradually become clogged. This not only significantly reduces water treatment efficiency but also increases the energy consumption of the pumping system. Therefore, to ensure the normal and efficient operation of the system, the filter screen must be cleaned or replaced regularly.

[0004] However, existing high-nitrate brine recovery devices have shortcomings in their filter installation and fixing structures. Typically, the filter is secured with multiple bolts or complex clips, making disassembly and installation cumbersome. This not only consumes a significant amount of time and reduces equipment maintenance efficiency but also usually requires specialized technicians using specialized tools, increasing labor costs. More seriously, during disassembly and assembly, limited operating space or improper force can easily cause deformation or direct damage to the delicate filter, leading to unnecessary waste of consumables.

[0005] Therefore, this utility model proposes a high nitrate brine recovery device to overcome the shortcomings of the prior art. Utility Model Content

[0007] This utility model provides a high-nitrate brine recovery device, including: a reaction vessel, an installation pipe disposed inside the reaction vessel, and a filter screen detachably sleeved on the outside of the installation pipe; and a disassembly mechanism for fixing or detaching the filter screen from the installation pipe.

[0008] The disassembly mechanism includes a support frame, a mounting frame, a fixing frame, a mounting block, a rotating plate, and a connecting assembly. The connecting assembly includes a mounting column, a sliding plate, and a spring.

By rotating the rotating plate, the mounting frame and the fixed frame are driven to move as a whole, thereby enabling the fixed frame and the support frame to be detachably snapped together. During the movement, the spring inside the connecting component is sleeved on the outside of the mounting column and cooperates with the sliding plate. Through the structural combination, the filter screen can be quickly, conveniently and without damage fixed and disassembled.

[0010] Preferably, the high nitrate brine recovery device further includes a support column fixedly connected to the bottom of the reactor, and a vibration damping mechanism disposed at the bottom of the support column.

[0011] Preferably, the vibration damping mechanism includes a fixing plate for fixing to the ground, a mounting column vertically fixed to the top of the fixing plate, a damper housed inside the mounting column, and a connecting assembly connected to the top of the mounting column and connected to the bottom of the support column.

[0012] Preferably, the connecting assembly includes an outer mounting cover fitted onto the top of the mounting column, a rubber anti-vibration pad, and a threaded post passing through the rubber anti-vibration pad and threadedly connected to the outer mounting cover, wherein the top end of the threaded post is fixedly connected to the bottom of the support column.

[0013] Preferably, the high-nitrate brine recovery device further includes a motor, which is mounted on top of the reactor.

[0014] Preferably, the mounting bracket is designed to surround the mounting tube.

[0015] Preferably, the top of the damper abuts against the connecting assembly.

[0018] 1.

[0032] Example:

[0033] Reference Figures 1 to 5 This utility model provides a high nitrate brine recovery device, which aims to solve the problems of complex filter screen disassembly and replacement process and easy damage to filter screen in the prior art, as well as the stability affected by vibration during equipment operation.

[0034] like Figure 1 As shown, the high nitrate brine recovery device includes a reaction vessel 1, with a support column 6 fixedly connected to the bottom of the reaction vessel 1 and a motor 2 installed on the top of the reaction vessel 1. An installation pipe 3 is installed inside the reaction vessel 1, and a filter screen 4 is detachably fitted onto the outside of the installation pipe 3. The filter screen 4 is fixed to the installation pipe 3 via a disassembly mechanism 5. A vibration damping mechanism 7 is installed at the bottom of the support column 6 to dampen vibrations in the reaction vessel 1. (Refer to...) Figure 2 and Figure 3 The disassembly mechanism 5 is used to fix or detach the filter screen 4 from the mounting tube 3. The disassembly mechanism 5 includes a support frame 53 fixed to the outside of the mounting tube 3 and a mounting frame 51, which surrounds the mounting tube 3. A fixing frame 52 is connected to the mounting frame 51. The inner wall shape of the fixing frame 52 is adapted to the outer wall shape of the support frame 53 to achieve detachable engagement with the support frame 53. A mounting block 54 is fixedly connected to the mounting frame 51, and a rotating plate 55 is rotatably connected to the mounting block 54. 5 is used to drive the mounting bracket 51 and the fixed bracket 52 to move; a connecting component 56 is provided between the mounting bracket 51 and the fixed bracket 52. The connecting component 56 includes a fixed post 562, one end of which is fixedly connected to the fixed bracket 52; the other end of the fixed post 562 is slidably connected to a sliding plate 561, which is slidably fitted inside the mounting bracket 51; a spring 563 is sleeved on the outside of the fixed post 562, and the two ends of the spring 563 abut against the sliding plate 561 and the fixed bracket 52 respectively.

[0035] Reference Figure 4 and Figure 5 The vibration damping mechanism 7 includes a fixing plate 71 for fixing to the ground. The top of the fixing plate 71 is vertically fixed to the mounting column 72. The mounting column 72 houses a damper 73. The top of the mounting column 72 is connected to a mounting assembly 74, which is connected to the bottom of the support column 6. The mounting assembly 74 includes a mounting cover 741 fitted onto the top of the mounting column 72 and a rubber anti-vibration pad 742. The mounting assembly 74 also includes a threaded post 743, which passes through the rubber anti-vibration pad 742 and is threaded to the mounting cover 741. The top of the threaded post 743 is fixedly connected to the bottom of the support column 6, and the top of the damper 73 abuts against the mounting assembly 74. This multi-stage vibration damping structure, which uses the rubber anti-vibration pad 742 for initial buffering and the damper 73 for deep energy absorption, ensures that the vibration generated by the motor 2 during operation can be effectively attenuated, thereby ensuring the stable operation of the core recovery function of the entire device.

[0036] As a preferred embodiment, in order to achieve stable circumferential fixation of the mounting tube 3, the overall structure of the mounting bracket 51 is arranged around the mounting tube 3. This structural layout ensures the concentricity and stability of the disassembly mechanism 5 on the mounting tube 3.

[0037] As another preferred embodiment, in order to ensure the reliability of the engagement between the fixing frame 52 and the support frame 53, the inner wall shape of the fixing frame 52 is adapted to the outer wall shape of the support frame 53. Through this shape matching, a tight fit can be formed during engagement, preventing relative shaking and thus achieving a stable lock.

[0038] In another preferred embodiment, in order to ensure that vibration energy can be efficiently transferred from the mounting assembly 74 to the damper 73, the top of the damper 73 abuts against the mounting assembly 74. Through gapless direct contact, it is ensured that the external vibration force can be quickly and completely transmitted to the damper 73 for absorption and dissipation.

[0039] The working principle is as follows:

[0040] When the filter screen 4 needs to be disassembled and replaced, the operator rotates the rotating plate 55 installed on the mounting block 54. The rotation of the rotating plate 55 causes the mounting frame 51 and the fixed frame 52 to move as a whole. During the movement, the sliding plate 561 in the connecting component 56 slides along the inside of the mounting frame 51. At the same time, the spring 563 sleeved on the outside of the fixed column 562 is compressed. This series of linkages causes the fixed frame 52 to finally disengage from the locking state of the support frame 53, thereby realizing the quick disassembly of the filter screen 4. The whole process does not require complicated tools, is easy to operate, and can effectively avoid damage to the filter screen caused by improper disassembly and assembly.

[0041] When the motor 2 installed on top of the reactor 1 starts and drives the device to run, the mechanical vibration generated is transmitted downward to the support column 6, and then absorbed by the vibration damping mechanism 7 at its bottom. The external vibration force first acts on the mounting component 74, and the vibration is buffered for the first stage by the rubber anti-vibration pad 742 connected by the threaded column 743. Then, the buffered vibration is transmitted through the mounting cover 741 to the damper 73 inside the mounting column 72. The damper 73 absorbs and dissipates most of the vibration energy, realizing the second stage of deep vibration reduction. Finally, the remaining small vibration is transmitted to the fixed plate 71. Through this multi-stage vibration reduction synergy, the overall vibration amplitude of the equipment is significantly reduced, ensuring the operational stability and service life of core components such as the pump body impeller.
