Description

Technical Field

[0001] The present invention relates to the technical field of material separation, and more specifically, to a material separation device and a control method for accurately removing iron without leaking material. Background Art

[0002] In the production process of cement, metallurgy, mining and other industries, the raw materials are usually accompanied by iron-containing impurities that are not conducive to production. They mainly come from two aspects: iron impurities in the raw materials and iron impurities caused by wear and tear of production equipment.

[0003] Iron impurities in raw materials: The main raw materials for cement production include limestone, clay and iron ore. During the mining, transportation and storage of these raw materials, some iron impurities, such as iron filings and rust, may be mixed in. These impurities will oxidize into iron slag during high-temperature calcination.

[0004] Iron impurities generated by wear of production equipment: During the cement production process, equipment such as mills and conveyor belts will produce iron filings due to wear during long-term operation. These iron filings will enter the production process along with the materials during the cement production process and eventually form iron slag.

[0005] Large iron particles can damage system equipment. To reduce the impact of iron impurities on cement production, iron removal measures need to be taken in each process of cement production. For example, in the limestone crushing and conveying process, limestone pre-homogenization process, clay crushing and conveying process, sandstone and iron bauxite crushing and conveying process, raw material batching process, raw material grinding process, cement batching process, cement grinding process, gypsum crushing and conveying process, raw coal conveying process and other links, certain iron removal measures can be taken according to process needs.

[0006] The pipeline iron remover is the most commonly used iron removal equipment in cement production. Its working principle is as follows: the iron remover is connected in series to the material conveying pipeline with an inclination of 45° to 75°. When the material flows through the iron remover, the ferromagnetic material in it is adsorbed to the stainless steel pipe wall of the pipeline iron remover, and gradually slides toward the iron outlet with the movement of the permanent magnet to achieve separation from the material. At the iron outlet, as the permanent magnet moves away in the direction of the circular motion, the ferromagnetic material loses its magnetic attraction and is discharged from the iron outlet under the action of gravity. Usually, the iron impurities are discharged into a pre-set container to achieve automatic iron removal of the material.

[0007] Since the outlet of the pipeline iron remover is connected to the pipeline, usually when removing iron impurities, some materials will be taken out of the system and discharged into the container storing iron impurities. In this process, the powdery materials will be raised, thus increasing the dust pollution in the workshop. Workers need to clean up the overflowed powder regularly, which indirectly increases the labor cost. Summary of the invention

[0039] The present invention is described in detail below.

[0040] like Figure 1-Figure 7 As shown:

[0041] A material separation device for accurate iron removal without leakage, comprising an iron removal component 1 installed in a conveying chute, a storage tank 2 installed at the bottom of the iron removal component 1 and connected to the iron removal component 1, a material separation component 4 installed at the bottom of the storage tank 2, and a chute component 3 arranged between the storage tank 2 and the material separation component 4; the chute component 3 comprises a chute 32, a gate valve 1 31 arranged between the chute 32 and the bottom of the storage tank 2, and a gate valve 2 33 arranged between the chute 32 and the material separation component 4; the storage tank 2, the chute component 3, and the material separation component 4 are connected in sequence;

[0042] The iron removal component 1 is a prior art, and its internal structure will not be described in detail here. Specifically, the iron removal component 1 can be a pipeline iron remover, which is connected in series to the outlet end of the material conveying pipe. When the mixed material flows through the pipeline iron remover, the iron impurities therein are adsorbed onto the stainless steel pipe wall of the pipeline iron remover, and gradually slide toward its outlet direction as the permanent magnet moves, thereby achieving separation from the powder material; at the outlet of the iron removal component 1, because the permanent magnet moves away along the direction of the circular motion, the ferromagnetic material loses its magnetic attraction and is discharged from the outlet of the iron removal component 1 under the action of gravity, thereby achieving automatic iron removal of the material.

[0043] The gate valve 1 31 and the gate valve 2 33 have the same structure, both of which are double-layer pneumatic gate valves, which can effectively realize automatic unloading and air locking and enhance sealing.

[0044] The material storage tank 2 is used to collect and store the materials discharged from the iron removal component 1 .

[0045] The control method specifically comprises the following steps:

[0046] The powder containing iron impurities enters the iron removal component 1 through the conveying chute, and a large amount of powder is discharged from the discharge port of the iron removal component 1. The iron-containing powder formed by the iron impurities and part of the powder is discharged to the storage tank 2 through the slag discharge port of the iron removal component 1;

[0047] When it is detected that the storage tank 2 is full of iron-containing powder, the gate valve 1 31 is opened and the vibration component 42 is started; the iron-containing powder enters the slide pipe 32; at this time, the gate valve 2 33 is in a closed state;

[0048] After all the iron-containing powder enters the chute 32, the gate valve 1 31 is closed, the gate valve 2 33 is opened, and the material enters the material separation component 4;

[0049] After all the iron-containing powder enters the material separation component 4, the gate valve 2 33 is closed; the iron-containing powder is screened in the material separation component 4, and the screened powder returns to the production system through the pipeline through the outlet 2 4121, and the large particles of iron impurities are discharged through the outlet 1 4111.

[0050] In some possible embodiments, the material separation component 4 includes a shell 41 with a feed port 410 on the top, a vibration component 42 installed on the outside of the shell 41, and a sieve plate 43 arranged in the shell 41 and dividing the shell 41 into chamber 1 411 and chamber 2 412; the chamber 1 411 is located above the chamber 2 412; the sieve plate 43 is flexibly connected to the vibration component 42; the gate valve 2 33 is installed on the feed port 410; the chamber 1 411 is provided with an outlet 1 4111 for discharging iron impurities, and the chamber 2 412 is provided with an outlet 2 4121 for discharging powder.

[0051] When in use, when the powder containing iron impurities is firstly deironed by the deironing assembly 1 and then transported to the housing 41 through the gate valve 33, the vibration assembly 42 drives the sieve plate 43 to vibrate, vibrates and screens the material transported from the feed port 410, and the screened powder passes through the sieve plate 43 and falls into the chamber 412 and is transported to the production system through the outlet 4121 for further use, and the screened iron impurities are discharged from the outlet 4111 of the chamber 411; specifically, the outlet 4121 is connected to the production system through a pipeline;

[0052] Furthermore, the sieve plate 43 is provided with a plurality of groups of holes for powder to pass through; large particles of iron impurities will not be able to pass through the holes and enter the second chamber 412 .

[0053] In some possible implementations, the vibration assembly 42 includes two groups of vibration reduction assemblies 421 symmetrically mounted on the housing 41 to form a cavity, a mounting plate 422 mounted in the cavity and respectively connected to the two groups of vibration reduction assemblies 421, and a vibration motor 423 mounted on the mounting plate 422; the mounting plate 422 is flexibly connected to the sieve plate 43;

[0054] The arrangement of the two sets of vibration reduction components 421 will effectively prevent the vibration force generated by the vibration motor 423 from being transmitted to the housing 41; specifically, the vibration component 42 is a rubber shock absorber;

[0055] The vibration motor 423 is installed on the mounting plate 422. Since the mounting plate 422 is flexibly connected to the sieve plate 43, when the vibration motor 423 vibrates, the exciting force generated will be transmitted to the sieve plate 43, so that the sieve plate 43 can achieve vibration screening and realize the separation of iron impurities and materials again.

[0056] In some possible embodiments, in order to effectively transmit the vibration force generated by the vibration motor 423 to the sieve plate 43, a transmission member 44 connected to the mounting plate 422 and the sieve plate 43 respectively is provided on the shell 41; a through hole connecting the cavity is provided on the shell 41, and the transmission member 44 is installed on the shell 41 and closes the through hole.

[0057] In some possible implementations, the transmission member 44 includes a rubber plate 441 installed on the outside of the housing 41 and used to close the through hole, and two groups of connecting plates 442 symmetrically arranged and located on the inner and outer sides of the rubber plate 441;

[0058] The connecting plate 442 located outside the rubber plate 441 is connected to the mounting plate 422, and the connecting plate 442 located inside the rubber plate 441 and inside the housing 41 is connected to the sieve plate 43;

[0059] Furthermore, a flange is provided on the outer side of the rubber plate 441, the flange is coaxially arranged with the through hole, the flange is fixedly connected with the housing 41 by bolts, the rubber plate 441 is located between the flange and the housing 41, and is fixed by the flange; a locking washer 444 is sleeved on the bolt, and the locking washer 444 prevents the bolt from loosening due to vibration;

[0060] Furthermore, the two sets of connecting plates 442 have the same structure and are angle steels, and are connected by bolts. A limiting washer 443 is sleeved on the outer side of the bolt, and the limiting washer 443 is sleeved inside the rubber plate 441, thereby limiting the pressure of the two sets of connecting plates 442 on the rubber plate 441;

[0061] The rubber plate 441 can seal the through hole to prevent dust generated during material separation from being discharged from the through hole to pollute the environment. At the same time, it can effectively transmit the vibration force generated by the vibration component 42 to the screen plate 43, driving the screen plate 43 to move and realize vibration screening.

[0062] The vibration force generated by the vibration motor 423 is transmitted to the screen plate 43 through the mounting plate 422, the angle steel outside the housing 41, and the angle steel inside the housing 41, thereby realizing the transmission of the vibration force;

[0063] In some possible implementations, the sieve plate 43 is arranged at an angle, wherein the distance between the side close to the vibration component 42 and the feed inlet 410 is smaller than the distance between the side away from the vibration component 42 and the feed inlet 410;

[0064] The sieve plate 43 is flexibly connected to the housing 41 at a side away from the vibration assembly 42, so that the sieve plate 43 can vibrate in the housing 41;

[0065] A material guide plate 4113 is further provided in the shell 41 and below the feed port 410; the distance between the end of the material guide plate 4113 close to the vibration component 42 and the feed port 410 is greater than the distance between the end of the material guide plate 4113 far from the vibration component 42 and the feed port 410; a material guide port is formed between the end of the material guide plate 4113 close to the vibration component 42 and the inner wall of the shell;

[0066] Through the above arrangement, the material coming out of the outlet of the storage trough 2 will be guided by the guide plate 4113 after entering the shell 41. Under the guidance of the guide plate 4113, the material falls onto the sieve plate 43 close to the side of the vibration component. At the same time, the sieve plate 43 vibrates up and down and left and right at high frequency. Under the action of the exciting force, the large particles of iron impurities in the material move downward along the inclined direction of the sieve plate 43, and are finally discharged from the outlet 1 4111, and the fine powder material falls into the outlet 2 4121 through the sieve holes.

[0067] The setting of the guide plate 4113 enables the material to be screened for a longer time on the screen plate 43, which improves the screening efficiency of the material and makes the screening more thorough.

[0068] In some possible implementations, a weight valve 4112 is provided on the outlet 1 4111, and the weight valve 4112 will be opened when the iron impurities in the chamber 1 411 need to be discharged;

[0069] In order to observe the material screening situation in the shell 41, an inspection hole is also arranged on the shell 41, and the inspection hole is connected with the chamber 411. An interface adapted to the inspection hole and a hole cover 45 installed on the interface and used to close the inspection hole are arranged on the outside of the shell 41; a sealing ring is arranged between the hole cover 45 and the interface.

[0070] Specifically, a flange is provided at one end of the interface away from the housing 41; the hole cover 45 is connected to the flange by bolts, and a sealing ring is provided between the flange and the hole cover 45 to achieve sealing at this position to avoid leakage at this position and pollution of the environment;

[0071] In some possible implementations, the material storage tank 2 includes a tank body 21 and a material level sensor 22 disposed on the tank body 21 and used to detect the position of the material in the tank body 21 .

[0072] The material level sensor 22 is a sensor for monitoring materials in the prior art, such as a photoelectric material level sensor; it is used to monitor the material collection and storage conditions in the tank body 21. When the maximum material level is collected, the gate valve 1 31 is closed, the gate valve 2 33 is opened, and the material passes through the gate valve 2 33 and enters the housing 41;

[0073] Furthermore, the present invention is also equipped with a control cabinet, which is installed on the shell and is electrically connected to the vibration motor 423, the gate valve 1 31, the gate valve 2 33, and the material level sensor 22, so as to realize linkage operation.

[0074] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
