Description

Technical Field

[0001] This utility model belongs to the field of mixing tank technology, specifically a mixing tank with screening feed. Background Technology

[0002] Magnesium carbonate is an important inorganic chemical material with good filling, dispersing, and flame-retardant properties. It is widely used in engineering plastics, refractory materials, boiler and pipeline insulation materials, and in the manufacture of magnesium salts, magnesium oxide, inks, glass, toothpaste, and other fields. The preparation of magnesium carbonate involves multiple steps, from raw material selection, pretreatment, and chemical reactions to product separation, purification, and packaging. Mixing tanks can be used to mix different chemical raw materials for reactions or the preparation of chemical products.

[0003] A search revealed a mixing tank (publication number CN206027612U) comprising a device body, a mixing chamber, a control box, a first feed pipe, and a second feed pipe. The mixing chamber is installed inside the device body, with the first and second feed pipes installed on one side of the mixing chamber. A circulating water pump is installed on the outside of the device body. A support is installed at the bottom of the device body. A liquid outlet pipe is installed at the bottom of the mixing chamber, with a manual valve installed on the upper side of the liquid outlet pipe. A corrosion-resistant outer shell is installed on the outside of the device body. The control box is also installed on the outside of the device body, with a setting button installed on its upper side. The output of the setting button is electrically connected to the input of a display. The automatic controller can automatically switch on the circulating water pump to extract and mix the drug after a certain feeding period, accelerating the mixing speed of the chemicals. Furthermore, the extracted drug is sprayed through a rotating nozzle, increasing the contact area and shortening the working time.

[0004] However, the above-mentioned patent does not screen the added raw materials during use, which will cause lumpy raw materials to enter the mixing tank as well. Moreover, the raw materials enter the mixing tank in a concentrated manner, resulting in uneven mixing between the raw materials, affecting the mixing quality of the raw materials, and thus affecting the use of the mixing tank.

[0024] Please see Figures 1-8, the present utility model provides a technical solution: a mixing tank for screening and feeding, including a mixing tank main body 1, an end cover 2 and a feeding pipe 3. The top end of the outer wall of the mixing tank main body 1 is connected with an end cover 2, and both sides of the top end of the end cover 2 are butted with a feeding pipe 3. Both sides of the bottom end of the mixing tank main body 1 are butted with a discharge pipe 4, and a base 5 is connected to the outer wall of the mixing tank main body 1. A driving motor 6 is installed in the middle of the top end of the end cover 2. A screening mechanism 7 is arranged inside the mixing tank main body 1, and the screening mechanism 7 includes a rotating rod 701, a filter sieve plate 702, a pulley 703, a spring 704, a guiding block 705, a receiving seat 706, a discharge hole 707, a transmission frame 708, a receiving cylinder 709, a fixed disk 710, a discharge groove 711, a rotating column 712, a stirring frame 713 and a scraping plate 714. The output end of the driving motor 6 is butted with a rotating rod 701, and the top end of the outer wall of the rotating rod 701 is sleeved with a filter sieve plate 702. And the outer side of the bottom end of the filter sieve plate 702 is connected with a pulley 703. The middle of the top end of the filter sieve plate 702 is connected with a spring 704. The outer wall of the pulley 703 is rollingly connected with a guiding block 705, and the bottom end of the guiding block 705 is welded with a receiving seat 706. And a discharge hole 707 is opened at the bottom end of the outer wall of the receiving seat 706; on one side of the rotating rod 701 close to the receiving seat 706 is sleeved with a transmission frame 708, and a receiving cylinder 709 is welded on the outer wall of the transmission frame 708. The middle of the inner wall of the mixing tank main body 1 is welded with a fixed disk 710, and a discharge groove 711 is opened inside the fixed disk 710; the outer wall of the receiving seat 706 is welded with the inner wall of the mixing tank main body 1, and the discharge holes 707 are distributed in a "cross" shape at the bottom end of the receiving cylinder 709. The discharge grooves 711 are distributed at equal angles inside the fixed disk 710, and the transmission frame 708 is designed in a "cross" shape structure; one side of the outer wall of the guiding block 705 is set as an inclined surface, and the other side of the outer wall of the guiding block 705 is set as a vertical surface. And the guiding blocks 705 are distributed at equal angles on the top of the receiving seat 706. An elastic telescopic mechanism is formed among the rotating rod 701, the filter sieve plate 702 and the spring 704; the bottom end of the outer wall of the rotating rod 701 is butted with a rotating column 712, and the middle of the outer wall of the rotating column 712 is sleeved with a stirring frame 713. And one side of the stirring frame 713 far from the rotating column 712 is connected with a scraping plate 714. The stirring frame 713 is designed in a "field" shape structure; a limiting pin 8 is welded at the bottom end of the outer wall of the end cover 2, and the outer wall of the limiting pin 8 is connected with a mounting seat 9 through a fixing hole. The inner wall of the mounting seat 9 is welded with the outer wall of the mixing tank main body 1, and the mounting seats 9 are distributed at equal angles on the top of the mixing tank main body 1; the outer wall of the scraping plate 714 is fitted with the inner wall of the mixing tank main body 1. The upper and lower sides of the spring 704 are fixedly connected with the rotating rod 701 and the filter sieve plate 702 respectively. Fixing holes corresponding to the limiting pin 8 are opened inside the mounting seat 9.

[0025] In practical implementation, when using this utility model, in order to screen the magnesium carbonate raw material entering the mixing tank body 1, after the raw material enters the mixing tank through the feed pipe 3, the drive motor 6 is started first. Since the output end of the drive motor 6 is connected to the rotating rod 701, the start of the drive motor 6 drives the rotating rod 701 to rotate. Then, the rotation of the rotating rod 701 drives the filter screen plate 702 to rotate. Since the bottom end of the filter screen plate 702 is connected to the pulley 703, the rotation of the filter screen plate 702 will drive the pulley 703 to rotate together. Then, the pulley 703 moves up along the inclined surface of the guide block 705, thereby generating an upward thrust on the filter screen plate 702, causing the filter screen plate 702 to move upward. When the filter screen plate 702 moves upward, it also compresses the spring 704, causing the bottom to deform. Then, as the filter screen plate 702 continues to rotate, when the pulley 703 moves past the inclined surface of the guide block 705 and reaches the vertical surface, the pulley 703 will be in a suspended state and move downward. At this time, the spring 704 resets and generates elastic force to drive the filter screen plate 702 to move downward, so that the filter screen plate 702 moves downward and collides with the receiving seat 706. As the filter screen plate 702 continues to rotate, the filter screen plate 702 will continuously repeat the above operation, thereby screening the raw materials in contact with it, so that the lumpy raw materials are shaken apart and then pass through the filter screen plate 702, thereby preventing the lumpy raw materials from entering the mixing area below.

[0026] When the screened raw material reaches the receiving seat 706, it is led out through the discharge hole 707 and contacts the fixed plate 710. Then, it is introduced into the mixing area from the discharge trough 711 below the discharge hole 707. Since the rotating rod 701 is connected to the transmission frame 708, the rotation of the rotating rod 701 will drive the transmission frame 708 to rotate together. The rotation of the transmission frame 708 will drive the receiving cylinder 709 to rotate together. Then, when the receiving cylinder 709 moves to the lower part of the discharge hole 707, the raw material led out from the discharge hole 707 will enter the receiving cylinder 709. Then, as the transmission frame 708 continues to rotate, the receiving cylinder 709 will move to the upper part of the discharge trough 711, which is not below the discharge hole 707. At this time, the raw material in the receiving cylinder 709 will be introduced into the mixing area from the discharge trough 711. This allows the raw material to enter the mixing area from multiple places, which can prevent the raw material from entering the mixing area in a concentrated manner, resulting in uneven mixing and affecting the mixing quality, thereby improving the mixing uniformity.

[0027] Furthermore, since the rotating rod 701 is connected to the rotating column 712, the rotation of the rotating rod 701 will drive the rotating column 712 to rotate, and the rotation of the rotating column 712 will drive the stirring rack 713 to rotate together. Then, as the stirring rack 713 rotates, the raw materials are mixed. Since the stirring rack 713 is connected to the scraper 714, the rotation of the stirring rack 713 will drive the scraper 714 to rotate together, scraping off the raw materials remaining on the inner wall of the mixing tank body 1, preventing the raw materials residue from affecting the mixing quality.

[0028] Since the end cap 2 is connected to the limiting pin 8, when it is necessary to open the top of the mixing tank body 1 to reveal its interior, simply move the end cap 2 upwards to disengage the limiting pin 8 from the mounting base 9, and the end cap 2 can be removed from the top of the mixing tank body 1.

[0029] In summary, when using this utility model, the mixing tank body 1 is first placed in a designated position using the base 5. Then, the raw materials for magnesium carbonate production are gradually added to the mixing tank through the feed pipe 3. Next, the drive motor 6 is started to drive the stirring frame 713 to rotate. At this time, the stirring frame 713 rotates to mix the various raw materials. After mixing, the mixture is discharged through the discharge pipe 4. This is existing technology and will not be elaborated on here. The screening mechanism 7 can screen the incoming raw materials, causing lumpy raw materials to be shaken apart and then passed through the filter screen plate 702, thereby preventing lumpy raw materials from entering the mixing area below. This allows the screened raw materials to enter the mixing area from multiple points, preventing the raw materials from concentrating in the mixing area and causing uneven mixing, which would affect the mixing quality and thus improve the mixing uniformity. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
