Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device for silane production. Background Art

[0002] Silane (SiH4), also known as silicane, is the most common one in a series of silicon hydrides. Silane is a colorless gas under normal temperature and pressure, with a pungent smell. Silane is highly flammable and can spontaneously combust in the air, generating silicon dioxide and water. It is usually used in fields such as semiconductor manufacturing, solar cell preparation, and silicone resin preparation. Industrially, silane is prepared by the Komatsu method (also known as the magnesium silicide process), specifically by reacting magnesium silicide with ammonium chloride in an ammonia environment. However, the tail gas wastewater generated during the preparation process contains a large amount of silicon dioxide particles and free ammonia. If it is directly discharged without treatment, it will not only pollute surface water and groundwater, but also deteriorate the air quality around the pollution source.

[0003] Existing wastewater treatment mechanisms usually use a filter press to carry out solid-liquid separation treatment on wastewater. The fixed impurities in the wastewater form filter cakes inside the filter plates of the filter press. Existing filter presses usually rely on gravity to make the filter cakes fall off naturally, but there are still some filter cakes adhering to the filter plates, affecting the solid-liquid separation effect of the filter press. If cleaned manually, on the one hand, the chemical substances in the filter cakes are likely to cause damage to the human body, and on the other hand, the cleaning efficiency is relatively low. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wastewater treatment device for silane production to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] Further, the supporting part includes a supporting block, on which a groove adapted to the side plate is provided. The supporting block is slidably connected in a spherical groove on the fixed block and is restricted within the spherical groove. A connecting rod is further fixedly connected to the bottom of the supporting block, and the connecting rod passes through the fixed block and is connected to the driving member.

[0009] Further, the driving member includes a turntable rotatably provided on the mounting frame. A limiting rod is fixedly connected to the turntable.

[0026] Through the provided lifting assembly 2 and discharging assembly 3, when the filter plate 11 moves to the upper side of the discharging assembly 3, the lifting assembly 2 drives the discharging assembly 3 to move upward, so that the supporting part 31 abuts against the side plate 12 on the filter plate 11. Under the action of the driving member 33, the driving member 33 drives the supporting part 31 to perform a swinging motion. The supporting part 31 slides in the spherical groove, so that the supporting part 31 drives the filter plate 11 to swing through the side plate 12, so as to shake off the filter cake on the filter plate 11, thereby completing the removal of the filter cake and ensuring the solid-liquid separation effect of the filter press.

[0027] Further, the lifting assembly 2 includes a hydraulic cylinder 21 fixedly arranged on the frame 1. The end of the hydraulic cylinder 21 is fixedly connected with a mounting frame 22. The mounting frame 22 is arranged in a U shape. The two discharging assemblies 3 are respectively arranged at both ends of the mounting frame 22 and are symmetrically arranged.

[0028] Further, the supporting part 31 includes a support block 311. A groove adapted to the side plate 12 is formed on the support block 311. The support block 311 is slidably connected in the spherical groove on the fixed block 32 and is restricted in the spherical groove. A connecting rod 312 is further fixedly connected to the bottom of the support block 311. The connecting rod 312 passes through the fixed block 32 and is connected with the driving member 33.

[0029] Further, the driving member 33 includes a turntable 331 rotatably arranged on the mounting frame 22. A limiting rod 332 is fixedly connected to the turntable 331.

The movement of the mounting frame 22 drives the discharging assembly 3 to move upward, so that the groove on the support block 311 is inserted into the side plate 12. The dual-axis motor 4 rotates to drive the turntable 331 to rotate. The rotation of the turntable 331 drives the driving rod 333 to swing through the cooperation of the limiting rod 332 and the driving groove 334. The swing of the driving rod 333 drives the connecting rod 312 to swing around the center of the spherical groove through the cooperation of the positioning rod 341 and the positioning groove 342. The swing of the connecting rod 312 drives the filter plate 11 to swing through the support block 311, thereby shaking off the filter cake adhering to the filter plate 11.

[0033] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
