Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a lithium carbonate filtration device. Background Technology

[0002] Lithium carbonate is used in the manufacture of lithium compounds, enamel, and glass. It is a raw material for producing lithium compounds and metallic lithium, and can be used as an additive in the electrolytic bath of aluminum smelting. It has wide applications in the glass, ceramics, pharmaceutical, and food industries, and can also be used in synthetic rubber, dyes, semiconductors, military and defense industries, televisions, atomic energy, pharmaceuticals, and catalysts.

[0003] In the lithium carbonate production process, if the lithium carbonate slurry particles are not uniform, it can easily cause wear on pump impellers, pipes, etc., and particulate solid impurities in the production line are not easy to remove. At present, most filters on the market use filter screens. When the processing volume is small, the filtration area is small, which can easily lead to clogging and fail to meet production needs. On the other hand, large processing volumes require a larger filtration area, which is limited by space. Utility Model Content

[0004] The purpose of this invention is to provide a lithium carbonate filtration device to solve the problem of small filtration area and easy clogging mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0007] Preferably, the left discharge port is equipped with a left discharge pipe, and the right discharge port is equipped with a right discharge pipe;

[0008] A second PTFE sealing gasket is installed between the top sealing cover and the titanium housing, and a first PTFE sealing ring is installed at the rear of the slag discharge port.

[0010] Preferably, the sieve plate has an inverted trapezoidal structure, and the sieve plate has several through-holes. A 5mm gap is reserved between the sieve plate and the four side walls of the titanium box.

[0011] Preferably, the inner side of the sieve plate is fixedly connected with a first rib, a second rib, and a third rib in sequence.

[0012] Preferably, a raised plate is installed on the inner bottom surface of the titanium tank, and the bottom end of the sedimentation outlet is flush with the top surface of the raised plate.

[0013] Preferably, curved corner blocks are fixedly connected to the four corners of the raised plate, and the inner surface of the curved corner blocks is curved.

[0014] Preferably, the titanium box body is fixedly connected to four corners at the bottom.

[0015] This utility model has the following technical effects:

[0016] The lithium carbonate filter not only achieves the function of large filtration area and is not easy to clog, but also achieves the function of slag discharge feedback and easy discharge of sediment.

[0017] (1) By setting up a transverse support frame, a first longitudinal support frame, a second longitudinal support frame, a sieve plate, a first rib, a second rib, a third rib, and sieve holes, when in use, lithium carbonate slurry is injected from the feed port, the support frame composed of the transverse support frame, the first longitudinal support frame, and the second longitudinal support frame supports the sieve plate, the bent sieve plate receives the lithium carbonate slurry, the sieve holes intercept large solid particles, the bent sieve plate has a larger filtration area, and its two sides are inclined, so the particles slide down under the action of gravity and are not easy to clog the sides. The first rib, the second rib, and the third rib can increase the structural strength of the sieve plate and make it not easy to deform. The filtered lithium carbonate slurry is discharged from the left outlet and the right outlet. The slag discharge port is opened periodically to discharge the slag, thus realizing the function of large filtration area and not easy to clog.

[0018] (2) By setting up a sensor wiring port and a weighing sensor, during use, as the slag accumulates during the filtration process, the weight of the screen plate will continuously increase. The weighing sensor senses the weight of the screen plate in real time, making it convenient for staff to read the data. The sensor wiring port is used for wiring and needs to be sealed during use, thus realizing the function of slag discharge feedback.

[0019] (3) By setting up a sedimentation outlet, curved corner blocks and a raised plate, when in use, the filtered lithium carbonate slurry will partially deposit at the bottom of the titanium tank. The curved corner blocks can reduce the difficulty of cleaning the corners of the titanium tank and gather the slurry to the raised plate. The raised plate raises the height of the sediment so that it can be discharged from the sedimentation outlet, thus realizing the function of easy discharge of sediment. Attached Figure Description

[0028] 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.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 6 As shown, this embodiment provides a lithium carbonate filtration device, including a titanium housing 1. The titanium housing 1 has a left discharge port 3 on the left side and a right discharge port 5 on the right side. The titanium housing 1 has a feed port 7 on the front side and a slag discharge port 8 on the rear side. A sieve plate 15 is installed inside the titanium housing 1. The bottom surface of the sieve plate 15 is not higher than the bottom of the feed port 7. A sedimentation discharge port 22 is provided on the lower part of the side wall of the titanium housing 1. A top sealing cover 10 is installed on the top surface of the titanium housing 1.

[0031] The design has been further optimized so that a left discharge pipe 4 is installed at the left discharge port 3 and a right discharge pipe 6 is installed at the right discharge port 5.

[0032] A second PTFE sealing gasket 11 is installed between the top sealing cap 10 and the titanium housing 1, and a first PTFE sealing ring 9 is installed at the rear of the slag discharge port 8. The left discharge port 3 and the right discharge port 5 have the same specifications, and the left discharge pipe 4 and the right discharge pipe 6 have the same dimensions.

[0033] In a further optimized design, two transverse support frames 12 are fixedly connected inside the titanium housing 1. A first longitudinal support frame 13 is fixedly connected between the transverse support frames 12 and the titanium housing 1. A second longitudinal support frame 14 is fixedly connected between the two transverse support frames 12. A sieve plate 15 is placed on the transverse support frames 12. A weighing sensor 21 is provided between the sieve plate 15 and the transverse support frames 12. A sensor wiring port 20 is provided on the side wall of the titanium housing 1.

[0034] Two sets of weighing sensors 21 are installed at the bottom of the transverse support frame 12. A sensor wiring port 20 is welded at the middle position on the right side of the titanium box 1. The top of the weighing sensor 21 passes through the transverse support frame 12 and extends to the outside. The top of the weighing sensor 21 is in contact with the bottom of the sieve plate 15, which is convenient for monitoring the amount of material slag accumulated inside.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the weighing sensor 21 senses the weight of the sieve plate 15 in real time, making it convenient for staff to read the data. The sensor wiring port 20 is used for wiring and needs to be sealed during use.

[0036] The scheme is further optimized. The sieve plate 15 has an inverted trapezoidal structure and several through-holes 19 are provided on the sieve plate 15. A 5mm gap is reserved between the sieve plate 15 and the four side walls of the titanium box 1.

[0037] The sieve holes 19 penetrate both the upper and lower surfaces of the sieve plate 15, providing a large filtration area and making it less prone to clogging.

[0038] The scheme is further optimized by fixing the first rib 16, the second rib 17, and the third rib 18 to the inner side of the sieve plate 15 in sequence.

[0039] The sieve hole 19 intercepts large solid particles, and the bent sieve plate 15 has a larger filtration area. With its inclined sides, the particles slide down under the action of gravity and are not easy to clog the sides. The first rib 16, the second rib 17, and the third rib 18 can increase the structural strength of the sieve plate 15 and make it less prone to deformation. The filtered lithium carbonate slurry is discharged from the left outlet 3 and the right outlet 5. The slag discharge port 8 is opened periodically to discharge the slag.

[0040] The design was further optimized by installing a raised plate 24 on the inner bottom surface of the titanium box 1, with the bottom of the sedimentation outlet 22 flush with the top surface of the raised plate 24.

[0041] The design is further optimized by fixing curved corner blocks 23 at the four corners of the raised plate 24, and the inner surface of the curved corner blocks 23 is curved.

[0042] A raised plate 24 is fixedly connected to the bottom of the interior of the titanium box 1. Arc-shaped corner blocks 23 are fixedly connected to the four corners of the raised plate 24. A sediment discharge port 22 is welded to the bottom of the right rear end of the titanium box 1. The bottom of the raised plate 24 is flush with the bottom of the interior of the sediment discharge port 22. The inner surface of the arc-shaped corner block 23 is arc-shaped to facilitate the discharge of sediment.

[0043] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the curved corner block 23 can reduce the difficulty of cleaning the corners of the titanium box 1 and gather the slurry to the raised plate 24. The raised plate 24 increases the height of the sediment so that it can be discharged from the sediment discharge outlet 22.

[0044] The design was further optimized by fixing feet 2 to the four corners of the bottom of the titanium housing 1.

[0045] Working Principle: In use, lithium carbonate slurry is first injected through inlet 7. A support frame consisting of a transverse support frame 12, a first longitudinal support frame 13, and a second longitudinal support frame 14 supports the screen plate 15. The bent screen plate 15 receives the lithium carbonate slurry, and the screen holes 19 intercept large solid particles. The bent screen plate 15 has a larger filtration area, and its inclined sides allow particles to slide down under gravity, preventing side blockage. The first rib 16, second rib 17, and third rib 18 increase the structural strength of the screen plate 15, making it less prone to deformation. The filtered lithium carbonate slurry is discharged from the left outlet 3 and the right outlet 5. The slag discharge port 8 is opened periodically to discharge slag. During filtration, the weight of the screen plate 15 increases with the accumulation of slag. The weighing sensor 21 senses the weight of the screen plate 15 in real time, facilitating data reading by operators. The sensor wiring port 20 is used for wiring and needs to be sealed during use. The filtered lithium carbonate slurry will partially deposit at the bottom of the titanium tank 1. The curved corner block 23 can reduce the difficulty of cleaning the corners of the titanium tank 1 and collect the slurry towards the raised plate 24. The raised plate 24 raises the height of the deposits so that they can be discharged from the sediment discharge outlet 22.
