Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrochemical purification metallurgical technology, specifically a multi-stage sieving device for dry titanium crystals. Background Technology
[0002] After drying, high-purity titanium crystals undergo magnetic separation for impurity removal, dry sieving and classification, and visual inspection before final packaging and warehousing. Traditionally, these three processes—magnetic separation for impurity removal, dry sieving and classification, and visual inspection—are performed separately before packaging and warehousing.
[0003] Currently, the separate operation between traditional processes leads to repeated handling of the same batch of materials, resulting in low overall efficiency. Simultaneously, the magnetic separator with magnetic rods placed in the funnel device experiences incomplete magnetic separation as the titanium crystal material continues to flow through, causing weakly magnetic impurities originally adsorbed on the magnetic rods to re-enter the packaging bag, resulting in incomplete impurity removal. The appearance inspection stage also involves inspecting the titanium crystal products inside the packaging bag. Since discolored or irregularly shaped titanium crystals constitute only a very small portion of the same batch, it is difficult to completely remove them when a large number of titanium crystals are accumulated inside the bag.
[0004] Therefore, in order to address the shortcomings of traditional screening processes, we propose a dry titanium crystal multi-stage screening device. Utility Model Content
[0005] This invention provides a multi-stage sieving device for dry titanium crystals, which automates the sieving process after the titanium crystals have been dried, improves sieving efficiency, and solves the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: a multi-stage screening device for dry titanium crystals, including a magnetic separator, a vibrating screen, and a linear belt conveyor. An inclined belt conveyor is provided at the outlet of the magnetic separator, and the other end of the inclined belt conveyor is connected to the vibrating screen. The linear belt conveyor is connected to the outlet of the vibrating screen. The magnetic separator includes a magnetic roller, and a feed hopper is provided at the top of the magnetic roller. A baffle plate for controlling the material feeding speed is provided inside the feed hopper. A protective cover is provided outside the magnetic roller, and a channel for the dry titanium crystals to flow in is reserved between the magnetic roller and the protective cover. The channel is connected to the feed hopper.
[0007] As an optional solution of the dry titanium crystal multi-stage screening device of this utility model, the ends of the channels are respectively a non-magnetic material channel and a magnetic material channel, the magnetic roller includes an outer sleeve, the inside of the outer sleeve is provided with a permanent magnet, and the permanent magnet is assembled on the side facing the non-magnetic material channel.
[0008] As an optional solution of the dry titanium crystal multi-stage screening device of this utility model, the inclined belt conveyor includes an inclined first support, the inner two ends of the first support are symmetrically provided with first idlers, the first belt is fitted between the first idlers, the first support is also provided with a first transmission motor for driving the first idlers to rotate, and the two ends of the first support are provided with matching transfer mechanisms corresponding to the discharge port of the magnetic separator and the feed port of the vibrating screen.
[0009] As an optional solution of the dry titanium crystal multi-stage screening device of this utility model, the linear belt conveyor includes a horizontally placed second support, with second idlers symmetrically arranged at both ends inside the second support, a second belt fitted between the second idlers, and a second transmission motor for driving the second idlers to rotate on the second support.
[0010] As an optional solution of the dry titanium crystal multi-stage screening device of this utility model, the vibrating screen includes a support, a screen is provided on the support, a vibrating motor for driving the screen to vibrate is provided inside the support, and a diversion channel is provided at the end of the support corresponding to the discharge port of the screen.
[0011] As an optional solution for the dry titanium crystal multi-stage sieving device described in this utility model, the screen is arranged in three layers from top to bottom, wherein the mesh size of the uppermost screen is 2mm, the mesh size of the middle screen is 1mm, and the mesh size of the lowermost screen is 0.5mm.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this type of multi-stage screening device for dry titanium crystals, a magnetic separator for magnetic separation and impurity removal, a vibrating screen for particle size screening, and a linear belt conveyor for manual picking are connected in series to form a whole. This avoids the problem of repeated handling of titanium crystal materials between processes, thereby automating the processing of titanium crystals after drying and making it possible to automate the entire titanium crystal post-processing production line.
[0014] 2. In this type of dry titanium crystal multi-stage screening device, the magnetic roller inside the magnetic separator is covered by a protective cover. Unscreened titanium crystals are poured in through the feed hopper at the top of the roller. The channel is set at the bottom of the roller, and the bottom discharge end of the channel is divided into a non-magnetic material channel and a magnetic material channel. This allows magnetic impurities in the dry titanium crystals to be discharged in time through the magnetic material channel after separation, avoiding the problem that magnetic impurities will re-enter and cause incomplete magnetic separation and impurity removal.
[0015] 3. In this type of dry titanium crystal multi-stage screening device, the titanium crystals after magnetic impurities are removed are directly transferred to the vibrating screen by the inclined belt conveyor. After the vibrating screen screens the particles by diameter, they are transported in a dispersed state to the linear belt conveyor for workers to sort them by color. This solves the problem that it is very difficult to sort accumulated titanium crystals manually. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: This example aims to address the problem of low overall efficiency caused by repeated handling of the same batch of materials due to separate operations between traditional processes. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 A multi-stage screening device for dry titanium crystals includes a magnetic separator 1, a vibrating screen 2, and a linear belt conveyor 3. An inclined belt conveyor 4 is located at the outlet of the magnetic separator 1, with the other end of the inclined belt conveyor 4 connected to the vibrating screen 2. The linear belt conveyor 3 is connected to the outlet of the vibrating screen 2. The inclined belt conveyor 4 includes an inclined first support 40, with first idler rollers 41 symmetrically arranged at both ends inside the first support 40. Both the first support 40 and the first idler rollers 41 are welded from 304 stainless steel. A first belt 42 is fitted between the first idler rollers 41. The belt 42 has a structure with a skirt and baffles. The first support 40 is also equipped with a first transmission motor for driving the first idler roller 41 to rotate. The transmission motor adopts a combination of frequency conversion motor and reducer to realize the transmission speed of the first belt 42 is adjustable. The two ends of the first support 40 are equipped with matching transfer mechanisms 43 corresponding to the discharge port of the magnetic separator 1 and the feed port of the vibrating screen 2. The transfer mechanism 43 matches the two ends of the first support 40 with the corresponding discharge port of the magnetic separator 1 and the feed port of the vibrating screen 2, thereby preventing titanium crystals from spilling during conveying.
[0025] In this embodiment: the magnetic separator 1 and the vibrating screen 2 are connected together by an inclined belt conveyor 4, and a straight belt conveyor 3 is set at the discharge end of the vibrating screen 2 to connect the magnetic separator 1 for magnetic separation and impurity removal, the vibrating screen 2 for particle size screening, and the straight belt conveyor 3 for manual picking into a whole, thereby avoiding the problem of repeated handling of titanium crystal materials between processes.
[0026] It should be noted that, as Figure 6 As shown, the magnetic separator 1, the vibrating screen 2, and the linear belt conveyor 3 can be placed at equal angles to each other or in a straight line, and can be adjusted according to the actual size of the factory.
[0027] Example 2 aims to address the problem of incomplete magnetic separation caused by magnetic impurities flowing continuously with the titanium crystal material in a funnel-shaped magnetic rod separator. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 , Figure 2 and Figure 4The magnetic separator 1 includes a magnetic roller 10, with a feed hopper 11 at the top of the magnetic roller 10. Inside the feed hopper 11 is an insert plate 110 for controlling the material feeding speed. The insert plate 110 controls the amount of titanium crystals flowing through the channel 13, thereby adjusting the feeding speed. The magnetic roller 10 is covered with a protective cover 12. A channel 13 for dry titanium crystals to flow in is reserved between the magnetic roller 10 and the protective cover 12. The channel 13 is connected to the feed hopper 11. The ends of the channel 13 are a non-magnetic material channel 130 and a magnetic material channel 131. The magnetic roller 10 includes an outer sleeve 100. Inside the outer sleeve 100 is a permanent magnet 101. The permanent magnet 101 is mounted on the side facing the non-magnetic material channel 130, and the side facing the magnetic material channel 131 is designed to be non-magnetic. Therefore, when magnetic impurities enter the non-magnetic side of the channel 13, they will fall naturally due to gravity.
[0028] In this embodiment: the dry titanium crystal material is manually transferred to the feed hopper 11 of the magnetic separator 1. At this time, by adjusting the position of the insert plate 110 in the feed hopper 11, the amount of dry titanium crystal material flowing through the channel 13 can be controlled. When the dry titanium crystal flows through the channel 13, the outer sleeve 100 of the magnetic roller 10 rotates counterclockwise under the drive of the motor. The magnetic titanium crystal or impurities are attracted to the sleeve by the permanent magnet 101. When it moves to the non-magnetic side, it falls naturally under the influence of gravity and enters the magnetic material channel 131 and is discharged from the magnetic separator 1. The non-magnetic normal titanium crystals directly converge along the channel 13 into the transfer mechanism 43 of the inclined belt conveyor 4, thereby avoiding the residue of magnetic impurities from affecting the screening of the magnetic separator 1.
[0029] Example 3 aims to facilitate the solution of the problem of how to sieve titanium crystals by particle diameter. This example is an improvement on Example 1. For details, please refer to Example 1. Figure 1 , Figure 3 and Figure 5 The vibrating screen 2 includes a support 20, a screen 21 is provided on the support 20, and a vibrating motor 22 is provided inside the support 20 to drive the screen 21 to vibrate. A diversion channel 23 is provided at the end of the support 20 corresponding to the discharge port of the screen 21. The screen 21 is arranged in three layers from top to bottom. The mesh size of the uppermost screen 21 is 2mm, the mesh size of the middle screen 21 is 1mm, and the mesh size of the lowermost screen 21 is 0.5mm.
[0030] In this embodiment: the second support 30 in the vibrating screen 2 is made of 304 stainless steel, and the screen 21 is made of TA2 titanium material. The screen 21 is arranged in three layers above the material flow channel. The uppermost screen 21 uses perforated mesh with a hole diameter of 2mm. The middle and lowermost screens 21 use woven mesh with a hole diameter of 1mm and a hole diameter of 0.5mm. This can separate the titanium crystal material flowing through the linear vibrating screen 2 into products with four particle sizes.
[0031] It should be noted that, according to the different particle diameters of the output after screening by the vibrating screen 2, a linear belt conveyor 3 can be set up to screen for different colors. When connecting, it can be connected by a transfer mechanism 43. Generally, the transfer mechanism 43 can be a pipe, inclined plate or other products.
[0032] Example 4 aims to address the issue of inspecting titanium crystal products inside packaging bags during the appearance quality inspection process. Because discolored or irregularly shaped titanium crystals constitute only a very small portion of the batch, the large accumulation of titanium crystals within the bag makes complete sorting difficult. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 , Figure 2 and Figure 3 The linear belt conveyor 3 includes a horizontally placed second support 30. The second support 30 has two symmetrically arranged second idlers 31 at its two ends. A second belt 32 is fitted between the second idlers 31. The second support 30 is also equipped with a second transmission motor for driving the second idlers 31 to rotate.
[0033] In this embodiment, the straight belt conveyor 3 has open sides, which can be used as workstations for workers to manually remove discolored or irregularly shaped titanium crystals. The end of the equipment can be directly connected to a packaging machine for packaging.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
