Description

Technical Field

[0001] The invention belongs to the technical field of zirconium oxychloride preparation, and in particular relates to a zircon sand feeding device. Background Art

[0002] Zirconium oxychloride (ZrOCl2·8H2O) is an important intermediate and is widely used in the preparation of other zirconium compounds, such as zirconium dioxide, zirconium carbonate, zirconium sulfate, etc. There are many methods for preparing zirconium oxychloride, including alkali fusion method, chlorination method and separation from zirconium oxychloride mother liquor. Among them, alkali fusion method is a commonly used method for preparing zirconium oxychloride, including alkali dissolution, leaching, membrane treatment concentration and cooling crystallization.

[0003] The alkali dissolution process involves the feeding of zircon sand. Traditionally, the feeding of zircon sand is intermittent, which requires the coordination of multiple employees. First, the zircon sand is accurately weighed and then hoisted to the designated location by a crane. This leads to inaccurate feeding, high labor intensity, low output, and easy restrictions by various factors. There is a serious waste of manpower and an unsafe working environment.

[0004] Therefore, the art needs to develop a zircon sand feeding device to reduce the labor intensity of zircon sand feeding operations, reduce manpower input, improve feeding accuracy and production efficiency, and improve the safety of the working environment. Summary of the invention

[0005] The purpose of the present invention is to provide a zircon sand feeding device to improve the feeding accuracy and production efficiency of zircon sand, reduce labor intensity, reduce manpower input, and improve the working environment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A zircon sand feeding device comprises a loading bin, an elevator, a feeding bin, an iron frame, a tube chain conveyor and a weighing device, wherein the loading bin is connected with a feeding pipe via a flexible joint, the feeding pipe is connected with the feeding port of the elevator, the discharging port of the elevator is connected with the feeding port of the tube chain conveyor, the tube chain conveyor is arranged above the feeding bin and the discharging port of the tube chain conveyor is arranged corresponding to the feeding port of the feeding bin, and the tube chain conveyor is connected to the iron frame via a bracket, the feeding bin and the loading bin are respectively connected to the corresponding iron frame via a weighing device, the bottom of the feeding bin is connected with a feeding pipe, the feeding pipe is provided with an electric discharging valve and an observation device, and the feeding pipe is provided with an electric feeding valve.

[0008] Preferably, the flexible joint is made of canvas, which is durable and inexpensive. When the elevator is running, it does not affect the accurate weighing of the materials in the upper bin and the feed bin by the weighing device.

[0009] When the above scheme is in use, the elevator and the tube chain conveyor are first started, and then the electric discharge valve on the discharge pipe is opened to allow the zircon sand in the upper bin to enter the elevator. Under the action of the elevator, the zircon sand is lifted to the feeding port of the tube chain conveyor, and then enters the feeding bin under the conveying action of the tube chain conveyor. The weighing device is used to instantly weigh the zircon sand in the feeding bin and the upper bin, and the observation device is used to observe whether there is blockage in the discharge pipe. When stopping feeding, the electric feeding valve and the electric discharge valve are closed first, and then the elevator and the tube chain conveyor are stopped in turn to prevent the zircon sand from being scattered or accumulated in each transfer link. The above process can realize efficient, accurate and mechanized feeding of zircon sand, thereby reducing manpower input and improving work efficiency and safety.

[0010] Preferably, the electric unloading valve and the electric feeding valve both adopt plum blossom offset valves. This solution adopts plum blossom offset valves, which has the advantages of quick response and precise control.

[0011] Preferably, the weighing device adopts a cantilever beam weighing sensor.

[0012] Preferably, the observation device comprises an observation port provided on the upper surface of the feed pipe and an arched tile body clamped on the top of the observation port, the arched tile body is embedded with transparent glass, and a handle is provided on the top of the arched tile body. This solution facilitates observation of whether the feed pipe is blocked, and the feed pipe can be opened and unblocked when necessary.

[0013] Preferably, a remote control cabinet is further included, and the hoist, the pipe chain conveyor, the weighing device, the electric unloading valve and the electric feeding valve are electrically connected to the remote control cabinet respectively. This solution is used to realize the automatic control of the zircon sand feeding operation.

[0014] Preferably, the elevator adopts a bucket elevator, and a collecting cavity is provided at the bottom of the bucket elevator, and the collecting cavity is in an inclined bucket shape, and a return port corresponding to the lowest position of the collecting cavity is provided on the side of the bucket elevator, and a spreading elevator is installed outside the side wall of the bucket elevator, and the feed end of the spreading elevator is connected with the return port, and the discharge port of the spreading elevator is connected with the upper bin through a material guide pipe, and the return port and the feed port of the elevator are respectively arranged on two adjacent side walls of the bucket elevator. This solution can ensure the continuous and stable operation of the bucket elevator. When the bucket elevator is working, there will be problems of material scattering and accumulation in the process of receiving and transmitting materials in the bucket. When there is a lot of material accumulation at the bottom of the bucket elevator shell, the bucket chain will be stuck and unable to operate. Usually, it is necessary to shut down and clean it manually, which is inconvenient for inspection and maintenance, with a large workload and a poor working environment. It also affects the continuous and stable feeding of zircon sand. The present application sets a bucket-shaped collecting chamber at the bottom of the bucket elevator, which is convenient for quickly collecting the zircon sand scattered in the bucket elevator to the return port, and then facilitates the material to be lifted into the upper bin by the scattering elevator, which is conducive to ensuring the efficient and stable operation of the bucket elevator.

[0015] Preferably, a material level alarm device is provided in the collecting cavity, and the material level alarm device is provided corresponding to the lowest position passed by the bucket of the bucket elevator. By providing the material level alarm device, the material spreading elevator can be started at any time as needed, which is conducive to realizing energy-saving operation of the device.

[0016] Preferably, the material level alarm device adopts a rotary resistance type material level meter.

[0017] Preferably, the material spreading elevator adopts a screw conveyor, and the screw conveyor is arranged vertically or inclined. The use of the screw conveyor can realize short-distance efficient, safe and stable transportation of the material spread in the bucket elevator.

[0018] Preferably, the screw conveyor and the material level alarm device are electrically connected to a remote control cabinet respectively, so as to facilitate automatic control.

[0019] The present invention also includes other devices or components that enable it to be used normally, all of which are conventional technical means in the field; in addition, devices, components or steps not limited in the present invention, such as rotary resistance level meters, bucket elevators, screw conveyors, tube chain conveyors, cantilever beam weighing sensors and remote control cabinets, all adopt conventional means in the field and will not be described in detail here.

[0020] The beneficial effects of the present invention are as follows: the present invention can improve the feeding accuracy and production efficiency when adding zircon sand, and at the same time facilitate continuous and stable operation, and help reduce labor intensity, reduce manpower input, and improve the working environment.

[0031] Example 1

[0032] Please refer to Figures 1 to 5 The present invention provides a zircon sand feeding device, comprising a feeding bin 1, an elevator 2, a feeding bin 4, an iron frame 12, a pipe chain conveyor 3 and a weighing device 6. The top of the feeding bin is provided with a checkered steel plate 14 (such as Figure 3As shown), the upper bin is connected with a lowering pipe through a flexible joint 7, the lowering pipe is connected with the feed port of the elevator, the discharge port of the elevator is connected with the feed port of the pipe chain conveyor, the pipe chain conveyor is arranged above the feed bin and the discharge port of the pipe chain conveyor is arranged corresponding to the feed port of the feed bin, and the pipe chain conveyor is connected to the iron frame through a bracket (not shown in the figure), the feed bin and the upper bin are connected to the corresponding iron frame through weighing devices respectively, the bottom of the feed bin is connected with a feeding pipe, the lowering pipe is provided with an electric lowering valve 8 and an observation device 10, and the feeding pipe is provided with an electric feeding valve 9.

[0033] Specifically, the flexible joint is made of canvas, which is durable and cheap. When the elevator is running, it does not affect the accurate weighing of the materials in the upper and feed bins by the weighing device. The end of the tube chain conveyor adopts a bell mouth design (please refer to Figure 2 ) can avoid the chain from getting stuck. The pipe of the pipe chain conveyor is also designed with sound insulation cotton (not shown in the figure) to ensure that the noise during operation is less than 85 decibels, which is used to improve the working environment.

[0034] Following the above embodiment, the electric unloading valve and the electric feeding valve both adopt plum blossom offset valves. By adopting the plum blossom offset valves, the device has the advantages of quick response and precise control.

[0035] In this embodiment, the weighing device adopts a cantilever beam weighing sensor.

[0036] Specifically, see Figure 4 The observation device includes an observation port provided on the upper surface of the feed pipe and an arched tile body clamped on the top of the observation port, the arched tile body is embedded with transparent glass, and a handle is provided on the top of the arched tile body. This solution makes it easy to observe whether the feed pipe is blocked, and to open and dredge the feed pipe when necessary.

[0037] See also Figure 1 In this embodiment, a remote control cabinet 5 is also included. The hoist, the pipe chain conveyor, the weighing device, the electric unloading valve and the electric feeding valve are electrically connected to the remote control cabinet respectively, and can be used to realize the automatic control of the zircon sand feeding operation.

[0038] Specifically, see Figure 1 and Figure 5 The elevator adopts a bucket elevator. In addition, guardrails 13 are correspondingly arranged on the bucket elevator, the loading bin, the feeding bin and the iron frame to improve the safety of daily inspection operations of the device. A ladder 16 is also arranged on the outer wall of the bucket elevator to facilitate the inspection and maintenance of the device. In some other embodiments, a feeding port can also be arranged on the side wall of the bucket elevator. The function of the feeding port is to facilitate manual re-addition in case of leakage.

[0039] When this embodiment is used, the elevator and the tube chain conveyor are first started, and then the electric discharge valve on the discharge pipe is opened to allow the zircon sand in the upper bin to enter the elevator. Under the action of the elevator, the zircon sand is lifted to the feeding port of the tube chain conveyor, and then enters the feeding bin under the conveying action of the tube chain conveyor. The weighing device is used to weigh the zircon sand in the feeding bin and the upper bin in real time, and the observation device is used to observe whether there is material blockage in the discharge pipe. When stopping feeding, first close the electric feeding valve and the electric discharge valve, and then stop the elevator and the tube chain conveyor in turn to prevent the zircon sand from being scattered or accumulated in each transfer link. The above process can realize the efficient, accurate and mechanized feeding of zircon sand, thereby reducing manpower input and improving work efficiency and safety.
