The utility model discloses a theory of operation and working process as follows:
(1) after unfiltered starch milk enters the screen 3 through the feed inlet 16 of the lower cylinder 2, the main speed reducer 15 drives the brush 5 to rotate, the brush 5 stirs the unfiltered starch milk to form a rotational flow, the unfiltered starch milk flows to the screen 3 under the combined action of pressure difference and the rotational flow, the unfiltered starch milk is filtered through the screen 3, the filtered starch milk is discharged through the discharge outlet 10, light impurities which cannot pass through the screen are gathered in the upper cover 11 through the water conservancy rotational flow principle, heavy impurities which cannot pass through the screen are gathered in the lower cylinder 2 through the gravity principle, the PLC control system 19 always detects the pressure difference between the unfiltered material pressure sensor 20 and the filtered material pressure sensor 17 in the operation process of the filter, the pressure of the unfiltered starch milk is gradually increased in the process of increasing the light and heavy impurities gathering, and when the pressure of the unfiltered starch milk is higher than the pressure of the filtered starch milk by 0.1MPa, it is shown that more impurities are gathered and can be discharged Put, PLC control system 19 can control light miscellaneous automatic discharge valve 30 in proper order and open under the circumstances of incessant feeding, and the control feeding is suspended after waiting light miscellaneous automatic discharge valve 30 to close, opens heavy miscellaneous automatic discharge valve 1 again, resumes the feeding after waiting heavy miscellaneous automatic discharge valve 1 to close, and the filter can not appear because of the filter residue piles up the phenomenon that takes place to block up after this process.
(2) After the brush 5 continuously rubs with the screen 3, the bristles at the end part of the brush are gradually shortened, and the spring 18 arranged between the brush 5 and the brush support 6 can provide pressure for the brush 5, so that the brush is always kept in contact with the screen 3, and the smooth operation of the filtering work is ensured.
(3) The existing filter transmission shaft sealing part is generally a packing sealing structure which is not suitable for high-pressure working conditions, and the friction between packing and a shaft can cause power loss. The filter changes a packing sealing structure into a mechanical sealing structure, reduces the friction resistance of a shaft, reduces energy consumption and can ensure no leakage under the high-pressure condition. Meanwhile, the connection mode of the main speed reducer 15 and the main shaft 7 is changed from the original coupling connection into the direct connection through the shaft sleeve 8, and the mechanical seal 9 is arranged on the shaft sleeve 8, so that the structure is simplified, the reliability is improved, and the maintenance is more convenient.
(4) When the brush 5 or the screen 3 is damaged and needs to be maintained and replaced, the worm and worm wheel 25 structure driven by the lifting speed reducer 27 can be controlled by the PLC control cabinet 19, automatic lifting of the upper cover of the filter and the rotating part can be realized, when the upper cover and the rotating part rise to the maintenance height or fall to the normal working height, the upper limit position switch 28 of the lifter or the lower limit position switch 21 of the lifter can transmit a signal to the PLC control cabinet 19, the PLC controls the lifting speed reducer 27 to stop, and the damage to equipment when the lifting exceeds the range is avoided by the function.
(5) The lifting support 12 is connected with the upper cover 11 through a pin shaft 13 and a positioning plate 14, so that the horizontal angle of the upper cover and the rotating part can be adjusted, and the blocking condition caused by the incorrect angle during the disassembly and the installation is avoided.
(6) The simple programming involved in the design and the control circuit of the PLC control cabinet 19 and each component can be easily realized by technicians in the industry, and the PLC control cabinet belongs to the prior art.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's self-cleaning filter, its simple structure, design benefit, rationally distributed, it is to the inherent defect that current starch milk filter exists, has set up the spring at first between brush and brush support, and this kind of structure can compress tightly the brush on screen cloth inner wall all the time, lets the brush after taking place wearing and tearing, still can contact with the screen cloth to guarantee going on smoothly of filtering work. Meanwhile, the original packing sealing structure is changed into a mechanical sealing structure, so that the friction resistance of a shaft is reduced, the energy consumption is reduced, and no leakage can be ensured under the high-pressure condition. Through the worm gear structure of lifting speed reducer driven, can realize the automatic promotion of filter upper cover and rotating part, lift support and upper cover are connected through round pin axle and locating plate within a definite time for horizontal angle can be adjusted to upper cover and rotating part, has avoided the jam condition emergence that causes because of the angle is not just when dismantling and installing. The light and heavy impurities are separated by gravity and water conservancy rotational flow, the material pressure is detected through the PLC system, the light and heavy impurities are controlled to be automatically discharged after being compared, and the phenomenon that filter residues are accumulated to block is avoided. The novel self-cleaning filter for automatically controlling starch milk treatment reduces the labor amount of operators, improves the working efficiency, accelerates the production rhythm, and has the advantages of low maintenance cost, low energy consumption, low cost and low labor intensity. The method has multiple advantages, is particularly suitable for popularization and application in the field, and has wide market prospect.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
