Referring again to fig. 1, the bottom of the main body support 1 is provided with a vibration motor 11, under the vibration action of the vibration motor 11, fine particles are easier to precipitate below larger particles, when the air bag 60 extrudes a filter cake in the filter pressing frame 22 above, the fine particles contact the air bag 60, the larger particles contact the filter cloth belt 5, and the phenomenon that the fine particles enter the filter holes of the filter cloth belt 5 is further reduced.
The bottoms of the front side plate and the rear side plate of the transmission frame 2 are respectively provided with a supporting block, and when the transmission frames 2 are extruded downwards by the hydraulic cylinder 3 driving connecting plate 31, the supporting blocks of the transmission frame 2 positioned above are supported on the transmission frame 2 positioned below, so that the filter pressing frame 22 positioned at the bottom of the transmission frame 2 positioned above is propped against the filter cloth belt 5 positioned in the transmission frame 2 positioned below.
The specific working principle of the filter press for chemical products is as follows: in the initial state, the part of the filter cloth belt 5 in each transmission frame 2 corresponding to the filter pressing frame 22 is positioned above the air bag belt 6 of the transmission frame 2, the filter pressing frame 22 positioned at the bottom of the transmission frame 2 positioned above is propped against the filter cloth belt 5 in the transmission frame 2 positioned below, chemical products are conveyed into the filter pressing frame 22 through the pump station 4, liquid in the chemical products enters a space formed by surrounding the filter cloth belt 5 after being filtered by the filter cloth belt 5 positioned below, flows to the left side of the filter pressing frame 22, and finally is discharged through the filter cloth belt 5 positioned at the left side of the filter pressing frame 22.
After the chemical is filled, a filter cake is initially formed in the filter pressing frame 22, the driving motor II 7 is controlled to drive the driving wheel 72 to drive the driving belt 71 to rotate anticlockwise, the first mounting block 73 on the driving belt 71 drives the first driving gear 731 to move forwards leftwards and rotate anticlockwise along the upper rack 25, the first upper gear 521 and the second upper gear 621 meshed with the first driving gear 731 drive the first upper driving shaft 52 and the second upper driving shaft 62 to rotate clockwise respectively, the second mounting block 74 on the driving belt 71 drives the second driving gear 741 to move forwards rightwards and rotate clockwise along the lower rack 26, the third driving gear 742 meshed with the second driving gear 741 rotates anticlockwise, and the first lower gear 541 and the second lower gear 641 meshed with the third driving gear 742 drive the first lower driving shaft 54 and the second lower driving shaft 641 to rotate clockwise respectively.
The first upper driving shaft 52 moves leftwards and rotates clockwise to roll the filter cloth belt 5 above the filter cloth belt 6 downwards, the first lower driving shaft 54 moves rightwards and rotates clockwise to lay the rolled filter cloth belt 5 rightwards, meanwhile, the second upper driving shaft 62 moves leftwards and rotates clockwise to lay the filter cloth belt 6 leftwards, and the second lower driving shaft 64 moves rightwards and rotates clockwise to convey the filter cloth belt 6 below the filter cloth belt 5 upwards, so that the filter cloth belt 5 and the filter cake cannot move relatively during the replacement position, and the replacement of the upper and lower positions of the filter cloth belt 5 and the filter cloth belt 6 is completed when the first supporting frame 9 and the second supporting frame 10 are completely unfolded and correspond to the filter pressing frame 22 up and down, and at the moment, the part of the filter cloth belt 6 corresponding to the filter pressing frame 22 is located above the filter cloth belt 5.
The pump station 4 is used for inflating the air bag 60, the air bag 60 upwards extrudes the filter cake, the filter cake upwards extrudes the filter press cloth belt 5, and as fine particles deposited at the bottom of the filter cake are in direct contact with the air bag 60, the top of the filter cake is mostly larger particles, so that the phenomenon that the fine particles enter filter holes of the filter press cloth belt 5 is reduced, liquid extruded in the filter cake enters a space formed by encircling the filter press cloth belt 5 above the filter press cloth belt 5, and the liquid is discharged through the part of the filter press cloth belt 5 positioned at the left side of the filter press frame 22.
After the press cake is extruded, the driving motor II 7 is controlled to drive the driving wheel 72 to drive the driving belt 71 to rotate clockwise, the first mounting block 73 on the driving belt 71 drives the first driving gear 731 to move forwards right along the upper rack 25 and rotate clockwise, the first upper gear 521 and the second upper gear 621 meshed with the first driving gear 731 drive the first upper driving shaft 52 and the second upper driving shaft 62 to rotate anticlockwise respectively, the second mounting block 74 on the driving belt 71 drives the second driving gear 741 to move forwards left along the lower rack 26 and rotate anticlockwise, the third driving gear 742 meshed with the second driving gear 741 rotates clockwise, and the first lower gear 541 and the second lower gear 641 meshed with the third driving gear 742 drive the first lower driving shaft 54 and the second lower driving shaft 64 to rotate anticlockwise respectively.
The first upper driving shaft 52 moves rightwards and rotates anticlockwise to lay the filter cloth strips 5 below the air bag strips 6 rightwards, the first lower driving shaft 54 moves leftwards and rotates anticlockwise to convey the filter cloth strips 5 below the air bag strips 6 upwards, meanwhile, the second upper driving shaft 62 moves rightwards and rotates anticlockwise to roll the air bag strips 6 downwards, and the second lower driving shaft 64 moves leftwards and rotates anticlockwise to lay the rolled filter cloth strips 5 leftwards, so that the filter cloth strips 5 and the air bag strips 6 do not move relative to filter cakes in the process of changing positions until the first supporting frame 9 and the second supporting frame 10 are folded, namely, the second upper driving shaft 62 passes through the filter pressing frame 22 rightwards, the first lower driving shaft 54 passes through the filter pressing frame 22 leftwards, the filter cloth strips 5 and the filter pressing strips 6 are completely replaced, and at the moment, the parts of the filter cloth strips 5 corresponding to the filter pressing frame 22 are located above the filter cloth strips 6, and the filter cakes are completely placed on the filter cloth strips 5.
The hydraulic cylinder 3 is controlled to shrink, the hydraulic cylinder 3 drives the transmission frame 2 at the top to move upwards along the main body support 1 through the connecting plate 31, the transmission frame 2 at the upper part drives the transmission frame 2 at the lower part to move upwards along the main body support 1 through the second folding rod 21, a discharge space is reserved between the adjacent transmission frames 2, then the driving motor I8 is controlled to drive the supporting shaft I51 to rotate anticlockwise, the supporting shaft I51 drives the filter cloth belt 5 to rotate, and filter cakes on the filter cloth belt 5 are discharged.
It will be appreciated that, to facilitate rapid drainage of the liquid in the filter cake, a drain hole may be provided in the left side of the rear side plate of the drive frame 2, and the portion of the space formed by the filter cloth belt 5 around the filter cloth belt 22 on the left side is communicated with the drain hole.
According to the filter press for chemical products, through arranging the filter cloth belt and the air bag belt and replacing the upper position and the lower position of the filter cloth belt and the air bag belt, when the air bag extrudes a filter cake, fine particles deposited on the bottom of the filter cake are not contacted with the filter cloth belt, the probability that the filter cloth belt is blocked due to the fact that the fine particles enter filter holes of the filter cloth belt in the extrusion process is reduced, the filter cloth belt is facilitated to be cleaned, the damage to the filter cloth belt when the filter cloth belt is cleaned is reduced, and the service life of the filter cloth belt is prolonged.
