Description

Technical Field

[0001] The utility model relates to the field of lactic acid powder production filtering equipment, in particular to a high-precision washable safety filter for lactic acid powder production. Background Art

[0002] Lactic acid powder, also known as powdered lactic acid, is a powdered product obtained by drying natural L-lactic acid produced by glucose fermentation. It is usually suitable for the food industry, pharmaceutical industry, and feed industry. In the food industry, it mostly acts as an acidulant and preservative to adjust the taste and flavor of food and extend the shelf life of food. In the process of producing lactic acid powder, in order to remove suspended matter, sediment, colloids and fine impurities in the liquid, a security filter is usually used to filter the liquid to prevent these particles from entering the subsequent processing equipment.

[0003] After using the security filter for a long time, a large amount of suspended matter, sediment, colloid and fine impurities will accumulate on the surface of the filter element inside the security filter. These impurities will clog the surface of the filter element, thereby reducing the filtering effect of the filter element. At the same time, too many impurities will also cause wear on the surface of the filter element, affecting the service life of the filter element. Therefore, it is necessary to regularly clean or overhaul the filter element inside the security filter;

[0004] At present, when inspecting the filter element inside the safety filter, it is necessary to first remove the filter element from the safety filter. However, the existing filter element is generally limited by a pressure plate to keep it stable inside the safety filter. When removing the filter element, it is necessary to first turn the knob on the top of the pressure plate to loosen the pressure plate before the filter element can be taken out. Such operation is relatively cumbersome and inconvenient for operators to perform maintenance work. At the same time, because the pressure plate is set on the top of the filter element, it will also cause certain obstructions to the liquid to be filtered, thereby affecting the filtering efficiency of the filter element.

[0005] Therefore, it is necessary to provide a new high-precision washable security filter for producing lactic acid powder to solve the above-mentioned technical problems. Utility Model Content

[0028] A sealing gasket 9 is also provided inside the card slot 19 at the bottom of the card plate 3. The sealing gasket 9 provided inside the card slot 19 can further increase the friction between the card slot 19 and the card block 5, thereby improving the stability of the card slot 19 when engaging with the card block 5.

[0029] The connecting piece includes a mounting plate 10 and a mounting column 11. One side of the mounting plate 10 is fixedly connected to one side of the mounting block 4. A threaded hole is provided on the surface of the mounting plate 10. The bottom of the mounting column 11 passes through the threaded hole and extends to the inner side of the security filter 1. The mounting column 11 is threadedly connected to the inner side of the security filter 1. Positioning rods 12 are provided on both sides of the mounting groove 6 opened at the top of the mounting block 4. Slots 13 matching the positioning rods 12 are provided on both sides of the card plate 3. A plurality of legs 14 are provided on the outer side of the security filter 1. When installing the filter element 2, the card plate 3 is placed along the mounting groove 6 opened at the top of the mounting block 4, and the card plate 3 is pressed to make the card plate 3 Move to the bottom end of the inner side of the installation groove 6, and make the inner side of the card slot 19 opened at the bottom of the card plate 3 contact with the outer side of the card block 5, continue to press the card plate 3, and squeeze the flexible rod 7 through the inner side of the card slot 19, so that the flexible rod 7 is deformed, so that the card plate 3 can continue to move inside the installation groove 6, when the limiting groove 8 opened on the inner side of the card slot 19 moves to the position of the flexible rod 7, the flexible rod 7 is no longer squeezed by the inner side of the card slot 19, so that the shape of the flexible rod 7 is restored, and at the same time, the outer side of the flexible rod 7 will fit with the inner side of the limiting groove 8, so as to continue to limit the card plate 3 and the filter element 2, and ensure its stability inside the security filter 1;

[0030] A water inlet pipe 15 is provided on the outside of the security filter 1, and the liquid to be filtered is transported to the inside of the security filter 1 through the water inlet pipe 15, and filtered by the filter element 2 arranged inside.

A sealing cover 17 is provided on the top of the security filter 1, and the sealing cover 17 is fixed by multiple locking structures 18.

[0031] The working principle of the utility model is as follows: the filter element 2 is pulled to drive the card plate 3 arranged on the outside of the filter element 2 to move in the direction away from the mounting block 4, and the outside of the flexible rod 7 is squeezed through the inner side of the limiting groove 8 to deform the flexible rod 7, so that the flexible rod 7 is separated from the inside of the limiting groove 8, and at the same time, the positioning rod 12 is squeezed through the inner side of the slot 13. Because the positioning rod 12 is made of a flexible material, when it is squeezed, the positioning rod 12 will be deformed, so that the card plate 3 will not be hindered by the positioning rod 12 when it is pulled out, and the filter element 2 is continued to be pulled until the card slot 19 opened at the bottom of the card plate 3 is no longer in contact with the outer side of the card block 5, and the filter element 2 is disassembled;

[0032] When installing the filter element 2, put the card plate 3 into the installation groove 6 opened on the top of the installation block 4, press the card plate 3, move the card plate 3 to the bottom end of the inner side of the installation groove 6, and make the inner side of the card groove 19 opened at the bottom of the card plate 3 contact with the outer side of the card block 5, continue to press the card plate 3, squeeze the flexible rod 7 through the inner side of the card groove 19, so that the flexible rod 7 is deformed, so that the card plate 3 can continue to move inside the installation groove 6, when the limiting groove 8 opened on the inner side of the card groove 19 moves to the position of the flexible rod 7, the flexible rod 7 is no longer squeezed by the inner side of the card groove 19, so that the shape of the flexible rod 7 is restored, and at the same time, the outer side of the flexible rod 7 will fit with the inner side of the limiting groove 8, so as to continue to limit the card plate 3 and the filter element 2, to ensure its stability inside the security filter 1;

[0033] During the installation of the filter element 2, the outer side of the card plate 3 will squeeze the positioning rods 12 arranged on both sides of the installation groove 6. Since the positioning rods 12 are made of flexible material, when they are squeezed, the positioning rods 12 will be deformed, so that the card plate 3 can continue to move inside the installation groove 6. When the slots 13 opened on both sides of the card plate 3 move to the position of the positioning rods 12, since the outer side of the card plate 3 is no longer in contact with the positioning rods 12, the shape of the positioning rods 12 will be restored, and at the same time, the outer side of the positioning rods 12 will fit the inner side of the slots 13, further improving the stability of the card plate 3.

[0034] By means of the sealing gasket 9 arranged on the inner side of the card slot 19, the friction force between the card slot 19 and the card block 5 can be further improved, thereby improving the stability when the card slot 19 and the card block 5 are engaged. By removing the mounting column 11, the mounting block 4 can be taken out from the inside of the security filter 1, and then the mounting block 4 and the inside of the mounting slot 6 can be cleaned. By means of the multiple legs 14 arranged on the outer side of the security filter 1, the stability of the security filter 1 during use can be improved.
