Description

Technical Field

[0001] This utility model belongs to the technical field of material unloading and conveying systems, and relates to an automatic buffer unloading and conveying device for highly wet and viscous mixed materials. Background Technology

[0002] In the hydrometallurgical workshop of a nickel smelter, in order to meet the needs of the production process, it is necessary to consider adding solid nickel concentrate or other high-moisture and viscous materials. Due to the physical properties of the mixture, when the moisture content is greater than 20%, it is easy to cause adhesion and blockage of the unloading and conveying devices. Severe adhesion will force cleaning and reduce the production efficiency of the workshop.

[0003] In the current hydrometallurgical workshop of the nickel smelter, feeding is done manually or using outdated equipment. Most of the outdated equipment is purely manual, consisting of a discharge valve at the bottom of the reaction tank, directly connected to a semi-open receiving and storage tank and a corresponding conveying pump. During operation, the discharge valve is opened, and the reacted mixture flows into the semi-open storage tank. The material in the tank is then pumped to the next process. However, the mixture entering the storage tank settles quickly, or cannot be pumped in time, easily accumulating into thick slag at the bottom of the tank, thus affecting its normal operation. Therefore, it often requires regular manual shovel cleaning. Due to the limited space in the storage tank, the cleaning cycle is long and labor-intensive, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the prior art by providing an automatic buffer unloading and conveying device for high-moisture and viscous mixtures. This device solves the problems of low production efficiency and inability to meet production needs caused by the traditional method of manually cleaning the bottom of storage tanks with shovels during the wet process in nickel smelting plants.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] An automatic buffer unloading conveying device for high-moisture viscous mixture includes a constant-force conveying pump installed on a ground platform. The constant-force conveying pump has a constant-force conveying pump inlet and a constant-force conveying pump outlet. A conveying pipe is provided above the constant-force conveying pump outlet. A screw conveyor is provided on the side of the constant-force conveying pump inlet, and the two are connected by a receiving chute.

[0007] The screw conveyor is provided with several screw conveyor inlets at the top and screw conveyor outlets and geared motors at both ends; a material reaction tank is provided above the screw conveyor inlets, the material reaction tank is set on a high platform, and its bottom is connected to the screw conveyor inlets through a guide pipe, and several buffer devices are provided inside the guide pipe in an alternating manner.

[0008] Furthermore, the buffer device includes a fixed bracket, which is L-shaped and has a first buffer plate and a second buffer plate arranged in parallel on its side, and the two are connected by a number of buffer springs; the first buffer plate is inclined and has a material baffle above it, and the material baffle is connected to the inner wall of the guide pipe by a pin.

[0009] Furthermore, the screw conveyor is provided with a protective net on its outer wall and conveying blades in the middle; the screw conveyor is horizontally arranged, and its bottom is connected to the ground platform through several support legs.

[0010] Furthermore, the conveying pipeline contains a highly viscous mixture.

[0011] Furthermore, the receiving chute is arc-shaped with its opening facing upwards.

[0012] Furthermore, the feed pipe is connected to the material reaction tank via a discharge gate valve.

[0013] Furthermore, the material baffle is inclined, and its inclination angle is smaller than that of the first buffer plate.

[0014] Furthermore, the two ends of the second buffer plate are respectively connected to the horizontal and vertical parts of the fixed bracket.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model can achieve buffer unloading in the vertical direction and conveying in the horizontal direction, thereby ensuring smooth and unblocked conveying of highly humid and sticky materials, and solving the problems of high manual labor intensity, low efficiency, and limitation of production efficiency improvement.

[0017] 2. This utility model adopts a centerless design, which eliminates the interference of the center shaft on the mixture. The openable protective net is convenient for inspection and maintenance. The mixture rotates in a circumferential "scraping" motion, which reduces or avoids the probability of high-moisture viscous mixture sticking to the wall.

[0018] 3. This utility model, by setting a spring buffer device inside the guide pipe, can avoid the problem of rapid and severe blockage of the screw conveyor inlet by high-moisture and viscous mixtures, ensuring smooth and unblocked discharge of the mixtures; at the same time, only a small geared motor or other power device is needed to achieve horizontal conveying, resulting in good energy-saving effect, improved production efficiency, and the advantages of simple installation and convenient maintenance.

Detailed Implementation

[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0024] like Figure 1 As shown, an automatic buffer unloading and conveying device for a high-moisture viscous mixture includes a constant-force conveying pump 3 installed on a ground platform 2. The constant-force conveying pump 3 has a constant-force conveying pump inlet 4 and a constant-force conveying pump outlet 5. A conveying pipe 6 is provided above the constant-force conveying pump outlet 5. Specifically, the conveying pipe 6 contains a high-moisture viscous mixture 7, which is a mixture of industrial water, anolyte, nickel-containing compounds, solutions containing impurities, viscous precipitates, etc.

[0025] The screw conveyor 10 has several screw conveyor inlets 12 at the top and screw conveyor outlets 11 and geared motors 13 at both ends. A material reaction tank 15 is located above the screw conveyor inlets 12. The material reaction tank 15 is set on the high platform 1, and its bottom is connected to the screw conveyor inlets 12 through a guide pipe 14. The guide pipe 14 is connected to the material reaction tank 15 through a discharge gate valve 16.

[0026] The feed tube 14 is internally equipped with several buffer devices 19 arranged in a staggered manner; such as Figure 2 and 3As shown, the buffer device 19 includes a fixed bracket 24, which is L-shaped. A first buffer plate 21 and a second buffer plate 25 are arranged in parallel on its side and connected by several buffer springs 20. The first buffer plate 21 is inclined, and a material baffle 22 is provided above it. The material baffle 22 is connected to the inner wall of the guide pipe 14 by a pin 23. The material baffle 22 is inclined at an angle smaller than that of the first buffer plate 21. The two ends of the second buffer plate 25 are connected to the horizontal and vertical portions of the fixed bracket 24, respectively. Specifically, the buffer device 19 uses the buffer springs 20 to create a vibratory conveying mechanism, reducing material impact, lowering the conveying speed, and allowing the mixed materials to fall smoothly and separately.

[0027] A screw conveyor 10 is provided on the side of the inlet 4 of the constant force conveying pump, and the two are connected by a receiving chute 8; specifically, the receiving chute 8 is arc-shaped and its opening faces upward.

[0028] The screw conveyor 10 is horizontally positioned, with its bottom connected to the ground platform 2 via several support legs 9. The outer wall of the screw conveyor 10 is equipped with a protective net 18, and the middle is equipped with conveying blades 17. Specifically, the conveying blades 17 are shaftless screw conveying blades. Specifically, when the screw conveyor 10 is working, the screw conveyor 10 provides power to the conveying blades 17 through a geared motor 13, and the conveying blades 17 rotate to push the material to complete the horizontal conveying operation.

[0029] In use, the high-moisture viscous mixture 7 flows into the screw conveyor inlet 12 through several buffer devices 19 in the guide pipe 14. At this time, the reduction motor 13 is turned on simultaneously. The reduction motor 13 drives the conveying blades 17 to rotate through the transmission device, which drives the high-moisture viscous mixture 7 to be quickly pushed to the screw conveyor outlet 11. It flows out naturally from the screw conveyor outlet 11 to the intermediate transition receiving chute 8. Finally, the high-moisture viscous mixture 7 is conveyed from the conveying pipe 6 to the next process by the constant force conveying pump 3. Thus, the unloading and conveying operation of the high-moisture viscous mixture 7 is completed.
