Description

TECHNICAL FIELD

[0001] The utility model relates to tungsten smelting equipment technical field, concretely relates to a tungsten ore acidolysis wastewater treatment device. BACKGROUND

[0002] Tungsten is a metal element with unique physical and chemical properties, known for its high melting point, high density, high hardness, and excellent corrosion resistance. These properties make tungsten irreplaceable in many industrial fields, especially in aerospace, shipping, automotive, electrical, electronic, and chemical industries. Due to these properties, tungsten performs particularly well in high-temperature, high-pressure, and corrosive environments, making it highly valuable economically and strategically in modern industry.

[0003] With the increasing awareness of environmental protection and the promotion of green production concepts worldwide, the smelting process of tungsten is constantly innovating and optimizing. In the traditional smelting process of tungsten ore, the use of ammonia produces ammonia-nitrogen pollutants, causing serious environmental pollution. To meet environmental protection requirements, ammonia-free smelting technology has emerged, which fundamentally eliminates the production of ammonia-nitrogen pollutants through innovative process flows. This technology not only effectively prevents the spread of ammonia-nitrogen during smelting, but also significantly reduces the difficulty and cost of ammonia-nitrogen pollution control. The promotion and application of ammonia-free smelting technology provide strong technical support for the sustainable development and green transformation of the tungsten smelting industry.

[0004] In the ammonia-free smelting process developed by our company, scheelite is subjected to acid washing and plate and frame pressure filtration to obtain tungsten-calcium material and acid washing wastewater. The tungsten-calcium material is subjected to complexing agent complexation leaching to obtain a crude tungsten acid solution. The crude tungsten acid solution is subjected to molybdenum extraction to obtain a pure tungsten acid solution. The pure tungsten acid solution is subjected to precipitation filtration, centrifugal drying, and drying calcination to obtain tungsten oxide. Among them, after the tungsten ore is acid washed, it needs to be separated from the acidolysis wastewater by a pressure filter. However, in actual application, after the solid-liquid mixed material is transported to the pressure filter, due to the limited carrying capacity of the pressure filter, multiple pressure filtrations are required to complete the separation of the material from the previous process, which becomes a short board that restricts the efficiency of the entire process. Therefore, it is necessary to design a device for pre-separation of wastewater. UTILITY MODEL CONTENTS

Obviously, the specific embodiments described are only part of the embodiments of the utility model, rather than all.

[0028] As shown in the drawings, Figures 1-6 The tungsten ore acidolysis wastewater treatment device comprises a sedimentation tank 10, the left upper end of the sedimentation tank 10 is provided with an inlet 101, tungsten-calcium material and wastewater mixture enter from the inlet 101, the right lower end of the sedimentation tank 10 is provided with an outlet 102 for discharging wastewater, and a grabbing mechanism 50 is arranged above the sedimentation tank 10 and used for fishing tungsten-calcium material deposited in the sedimentation tank 10. The grabbing mechanism 50 is provided with a translation mechanism 30 on the front and back sides, and the translation mechanism 30 is used for driving the grabbing mechanism 50 to move left and right.

[0029] The sedimentation tank 10 is provided with two first partitions 103 and a second partition 106 in the front-rear direction, so that the sedimentation tank 10 is divided into a chamber one, a chamber two, a chamber three and a filter tank from left to right. The rear part of the first partition 103 between the chamber one and the chamber two is provided with a gap, the front part of the first partition 103 between the chamber two and the chamber three is provided with a gap, and the second partition 106 between the chamber three and the filter tank is not provided with a gap in the front-rear direction and has a height lower than that of the first partition 103. After the tungsten-calcium material and wastewater mixture enter from the inlet 101, the tungsten-calcium material forms a deposit in the chamber one, the chamber two and the chamber three, and the wastewater overflows from the second partition 106 and enters the filter tank. The bottom of the filter tank is designed to be high at the back and low at the front, so that the wastewater can be discharged from the outlet 102. The filter tank is provided with a filter screen 104 in a multi-layer structure, and the filter screen 104 is fixedly connected with a handle 105 at the front and back ends. A small amount of tungsten-calcium material mixed in the wastewater can be filtered through the filter screen 104, and the handle 105 facilitates cleaning of the filter screen 104.

[0030] The grabbing mechanism 50 comprises a fixed seat 501, a motor gear module three, a movable seat 503 and a digging part. The motor gear module three is fixedly connected to the fixed seat 501. The digging part comprises a fixed rod 504, an electric push rod 505 and a bucket 506. The upper end of the fixed rod 504 is fixedly connected to the bottom of the movable seat 503, and the bottom of the fixed rod 504 is hingedly connected to one side of the upper end of the bucket 506. The bottom of the electric push rod 505 is hingedly connected to the bottom of the movable seat 503, and the telescopic end of the electric push rod 505 is hingedly connected to the other side of the upper end of the bucket 506. A guide rail and a rack are fixedly connected to the movable seat 503. A guide sleeve that is engaged with the guide rail of the movable seat 503 is fixedly connected to the fixed seat 501. The gear of the motor gear module three is engaged with the rack of the movable seat 503. The gear of the motor gear module three is driven to rotate by the motor gear module three, so as to drive the movable seat 503 and the digging part to move up and down. The rotation of the bucket 506 is driven by the telescopic movement of the electric push rod 505.

[0031] The sedimentation tank 10 is equipped with supports 20 on both the front and rear sides. A guide rail and a rack are fixedly connected to the upper end of each support 20. The translation mechanism 30 includes a motor gear module one. A guide sleeve that meshes with the guide rail at the upper end of the support 20 is fixedly connected to the bottom of the motor gear module one. The gear of the motor gear module one meshes with the rack at the upper end of the support 20. A crossbeam 40 is fixedly connected between the two motor gear modules one. A guide rail and a rack are fixedly connected to the upper end of the crossbeam 40. A motor gear module two is fixedly connected to the fixed base 501. A guide sleeve that meshes with the guide rail at the upper end of the crossbeam 40 is fixedly connected to the bottom of the motor gear module two. The gear of the motor gear module two meshes with the rack at the upper end of the crossbeam 40. The first motor gear module drives the gears to rotate, causing the crossbeam 40 and the gripping mechanism 50 to move left and right. This allows the gripping mechanism 50 to dig out the precipitated tungsten-calcium material at different positions in chamber one, chamber two, and chamber three, and to move to the far left for unloading. The second motor gear module drives the gears to rotate, causing the two gripping mechanisms 50 to move apart or close together. This allows the two buckets 506 to close together after digging out the precipitated tungsten-calcium material, and then lift it upwards for transfer.

[0032] When using this device, the mixture of tungsten-calcium material and wastewater enters chamber one through inlet 101, then flows through chamber two to chamber three. The tungsten-calcium material settles at the bottom. Once chamber three is full, the wastewater at the top overflows from the second partition 106 into the filtration tank. A small amount of mixed tungsten-calcium material can be filtered through filter screen 104. The first motor gear module drives its gears to rotate, moving the crossbeam 40 and the gripping mechanism 50 above chamber one, two, or three. The second motor gear module drives its gears to rotate, causing the two gripping mechanisms 50 to separate, and the electric push rod 505 retracts. At this time, the gripping mechanism 50 is in the following state: Figure 5 As shown, the motor gear module three drives its gears to rotate, causing the movable seat 503 and the digging part to slowly move downwards to the lowest point of their stroke to dig out the tungsten-calcium material. After digging, the electric push rod 505 slowly extends, and the motor gear module two drives its gears to rotate, causing the two gripping mechanisms 50 to slowly approach each other. The motor gear module three drives its gears to rotate, causing the movable seat 503 and the digging part to slowly move upwards. At this time, the state of the gripping mechanism 50 is as follows. Figure 6 As shown, the first motor gear module drives its gears to rotate, causing the crossbeam 40 and the gripping mechanism 50 to move to the leftmost position for material feeding. The second motor gear module drives its gears to rotate, causing the two gripping mechanisms 50 to separate, and the electric push rod 505 to retract, allowing the tungsten-calcium material to fall into the receiving device. Repeating the above actions can continuously extract and transfer the tungsten-calcium material in chamber one, chamber two, or chamber three.
