Description

Technical Field

[0001] The present invention relates to the field of mine equipment for clean production, and specifically, to an immersion-type drum ore washer. Background Art

[0002] An ore washer, also known as a sorting feeder, is used for cleaning muddy ore before the beneficiation process to improve the beneficiation index of the subsequent process. It is commonly used for washing ores such as manganese ore, iron ore, limestone, tungsten ore, tin ore, and silica sand ore. The ore washer is a large-scale equipment used in black and non-ferrous metallurgical mines, steel, metallurgy, chemical industry, and building materials to wash ores and stones. The ore washer has a large processing capacity and is an ideal equipment for enterprises with high productivity requirements for the cleanliness of ores and stones. Washing ores can prevent the muddy substances in the muddy mineral raw materials from clogging the crushing and screening equipment. If the raw materials contain soluble useful or harmful components, ore washing is also required.

[0003] The ore washer also includes a trough-type ore washer and a drum ore washer, and both types of ore washers have their own advantages. For the drum ore washer, due to the limitation of its structure, compared with the trough-type ore washer, the soaking time of the ore during the ore washing process is very short. Therefore, compared with the trough-type ore washer, the large ore washing volume of the drum ore washer is its advantage, but the lower cleanliness of the ore washing effect is its disadvantage. Summary of the Invention

[0004] The purpose of the present invention is to provide an immersion-type drum ore washer to solve the problem of poor ore washing ability of the existing drum ore washer.

[0005] To solve the above problems, the present invention adopts the following technical means:

[0006] An immersion-type drum ore washer includes a horizontal ore washing barrel. The discharge end of the ore washing barrel is coaxially connected to a filtering barrel. The feeding end of the ore washing barrel is coaxially and rotatably installed with a baffle plate. A columnar water tank is coaxially arranged inside the ore washing barrel. The side wall of the water tank is evenly distributed with spray nozzles. One end of the water tank facing away from the filtering barrel is connected to a water inlet channel. The water inlet channel passes through the baffle plate and is connected to a pressure water pump. The baffle plate is also connected to a feeding channel. The space between the outer wall of the water tank and the inner wall of the ore washing barrel is used for washing materials. The discharge end of the filtering barrel is also coaxially provided with a sealing plate. The outer diameter of the sealing plate is the same as the inner diameter of the ore washing barrel. The sealing plate is slidably arranged inside the ore washing barrel. A waterproof rotating motor is installed at one end of the water tank facing the filtering barrel. The rotating end of the rotating motor is installed with a threaded rod and the threaded rod penetrates along the axis of the filtering barrel. The threaded rod is threadedly connected to the sealing plate. A limiting rod parallel to the threaded rod is also installed at one end of the water tank facing the filtering barrel. The limiting rod passes through the sealing plate and is slidably connected to the sealing plate.

[0007] Preferably, a sealing ring is covered on the outer edge of the sealing plate, and the sealing ring is in sliding contact with the inner wall of the ore washing barrel. There are a pair of limiting rods, and the two limiting rods are symmetrically arranged about the axis of the threaded rod. A pressure valve is arranged in the water spray head.

[0008] Further, a through embedding channel is arranged on the end wall of the ore washing barrel facing away from the filtering barrel. An embedding groove surrounding its axis is arranged on the outer edge of the baffle plate. The inner wall of the embedding channel is slidably embedded in the embedding groove.

[0009] Preferably, a pair of support ring grooves are arranged around the axis of the outer wall of the ore washing barrel. A pair of support wheels are rotatably installed in the support ring grooves. The axis of the support wheels is parallel to the axis of the ore washing barrel. The support wheels in each support ring groove are symmetrically arranged about the middle vertical plane of the ore washing barrel, and each support wheel is coaxially connected to the rotating end of a rotating motor.

[0010] Furthermore, a rubber ring is coaxially covered and installed on the outer wall of the support wheel, and the rubber ring is embedded in the support ring groove.

[0011] Furthermore, the end of the threaded rod extending out of the filtering barrel is rotatably installed on the limiting plate. The threaded rod is rotatably connected to the limiting rod through a rotating bearing. A limiting hole is also arranged on the limiting plate. The limiting rod horizontally passes through the limiting hole. A support column is installed on the bottom surface of the limiting plate.

[0012] Furthermore, the support wheel is rotatably installed on the support frame. The support frame is installed on the top surface of the base. The rotating motor is also arranged on the base. The bottom end of the support column is connected to the base. A horizontally through water outlet channel is arranged on a section of the base below the filtering barrel. A water blocking plate extending upward is arranged on the inner wall of the water outlet channel. The water blocking plate extends along the shape of the outer wall of the filtering barrel, and a water passing channel is arranged between the water blocking plate and the outer wall of the filtering barrel.

[0013] Furthermore, a number of material plates for stirring are distributed on the inner wall of the ore washing barrel.

[0014] During the use of the present invention, the following beneficial effects are achieved:

[0015] When washing ore, the ore to be washed is input into the ore washing barrel through the feeding channel, and the ore washing barrel is separated from the filtering barrel by using a sealing plate. At the same time, the sealing plate makes the ore washing barrel in a state of being closed at both ends. Then, water is injected into the water tank through the water inlet channel. When the water in the water tank is full and the water pressure is greater than the pressure of the water spray head, the water in the water tank continuously sprays from the water spray head into the ore washing barrel. Along with the rotation of the ore washing barrel, the ore in the ore washing barrel is cleaned. At the same time, as the water sprayed from the water spray head in the ore washing barrel gradually increases, the ore in the ore washing barrel can gradually be in a state of immersion washing. Combined with the rotation of the ore washing barrel, the ore sand can be better cleaned in the ore washing barrel. After the ore washing is completed, the rotation motor is started, and the threaded rod installed at the rotating end of the rotation motor rotates. At the same time, under the action of the limiting rod, the sealing plate cannot rotate and can only move back and forth along the axis of the threaded rod in a state of being threadedly connected to the threaded rod. In this way, by controlling the rotation of the threaded rod, the sealing plate enters the filtering barrel from the ore washing barrel, so that the discharging end of the ore washing barrel is opened, and the ore after immersion washing enters the filtering barrel for filtration, discharging the sandy sewage, and the washed ore sand moves along with the filtering barrel and finally discharges from the discharging end of the filtering barrel. Compared with the common drum-type ore washing, the ore washing process of this application can make the ore sand in a state of immersion washing, not only having the advantages of convenient and efficient ore discharging of the cylindrical ore washing machine, but also effectively solving the problem of poor ore washing effect of the conventional cylindrical ore washing machine.

[0027] Please refer to Figures 1 to 4As shown in the figure, a dipping drum ore washer includes a horizontal ore washing barrel 1. The discharge end of the ore washing barrel 1 is coaxially connected to a filtering barrel 2. The feeding end of the ore washing barrel 1 is coaxially and rotatably installed with a baffle plate 3. A columnar water tank 4 is coaxially arranged in the ore washing barrel 1. The side wall of the water tank 4 is evenly distributed with spray nozzles. One end of the water tank 4 facing away from the filtering barrel 2 is connected to a water inlet channel 6. The water inlet channel 6 passes through the baffle plate 3 and is connected to a pressure water pump. A feeding channel 7 is also connected to the baffle plate 3. The space between the outer wall of the water tank 4 and the inner wall of the ore washing barrel 1 is used for cleaning materials. The discharge end of the filtering barrel 2 is also coaxially provided with a sealing plate 8. The outer diameter of the sealing plate 8 is the same as the inner diameter of the ore washing barrel 1. The sealing plate 8 is slidably arranged in the ore washing barrel 1. A waterproof rotating motor 9 is installed at one end of the water tank 4 facing the filtering barrel 2. The rotating end of the rotating motor 9 is installed with a threaded rod 10 and the threaded rod 10 penetrates along the axis of the filtering barrel 2.

[0028] In this way, when washing ore, the ore to be washed is input into the ore washing barrel 1 through the feeding channel 7, and the ore washing barrel 1 and the filtering barrel 2 are separated by the sealing plate 8. At the same time, the sealing plate 8 makes the ore washing barrel 1 in a closed state at both ends. Then, water is injected into the water tank 4 through the water inlet channel 6. When the water in the water tank 4 is full and the water pressure is greater than the pressure of the spray nozzles 5, the water in the water tank 4 continuously sprays from the spray nozzles 5 into the ore washing barrel 1. Along with the rotation of the ore washing barrel 1, the ore in the ore washing barrel 1 is cleaned. At the same time, as the water sprayed from the spray nozzles 5 in the ore washing barrel 1 gradually increases, the ore in the ore washing barrel 1 can gradually be in a dipping state. Combined with the rotation of the ore washing barrel 1, the ore sand can be better cleaned in the ore washing barrel 1. After the ore washing is completed, the rotating motor 9 is started, and the threaded rod 10 installed at the rotating end of the rotating motor 9 rotates. At the same time, under the action of the limiting rod 11, the sealing plate 8 cannot rotate and can only move back and forth along the axis of the threaded rod 10 in the state of being threadedly connected to the threaded rod 10. In this way, by controlling the rotation of the threaded rod 10, the sealing plate 8 enters the filtering barrel 2 from the ore washing barrel 1, so that the discharge end of the ore washing barrel 1 is opened, and the dipped ore enters the filtering barrel 2 for filtering, discharging the sand-containing sewage, and the washed ore sand moves along with the filtering barrel 2 and finally is discharged from the discharge end of the filtering barrel 2. Compared with the common drum ore washer, the ore washing process of this application can make the ore sand in a dipping state, not only having the advantages of convenient and efficient ore discharge of the cylindrical ore washer, but also effectively solving the problem of poor ore washing effect of the conventional cylindrical ore washer.
