It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0030] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0031] The following describes a plate - type filter for water - based coatings provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0032] Example 1: In combination with Figures 1 to 6As shown in the figure, a plate filter for waterborne coatings provided by the utility model includes an angle adjustment mechanism 100, a stability enhancement and protection mechanism 200 arranged inside the angle adjustment mechanism 100, a pressure filtration and slag discharge mechanism 400 arranged inside the stability enhancement and protection mechanism 200, and four groups of filter bag pressurization mechanisms 300 arranged on the stability enhancement and protection mechanism 200. The angle adjustment mechanism 100 is used to provide an inclined angle support for filtering the coatings by the pressure filtration and slag discharge mechanism 400. The stability enhancement and protection mechanism 200 is used to cooperate with the pressure filtration and slag discharge mechanism 400 to provide anti-burst protection for the filter bags. The four groups of filter bag pressurization mechanisms 300 are used to provide selective four-point pressurization for the vibration of the pressure filtration and slag discharge mechanism 400.

[0033] The stability enhancement and protection mechanism 200 includes two anti-overflow outer plates 210, a first baffle 220 arranged between the two anti-overflow outer plates 210, two positioning plates 230 inserted inside the two anti-overflow outer plates 210, a chassis 240 installed on the outer side of one of the anti-overflow outer plates 210, a motor 250 installed inside the chassis 240, a turntable 260 installed on the transmission shaft of the motor 250, a first pull rod 270 movably installed on the turntable 260, a second pull rod 280 movably installed at the other end of the first pull rod 270, and a guide rod 290 installed at the other end of the second pull rod 280;

[0034] The pressure filtration and slag discharge mechanism 400 includes a sieve plate 410 and a suspension 420 arranged between the two anti-overflow outer plates 210, a filter bag 460 arranged on the top of the sieve plate 410, a plurality of pressing plates 430 arranged inside the suspension 420, an expansion mask 490 arranged inside the top end port of the filter bag 460, a slag discharge cover 440 arranged inside the bottom end port of the filter bag 460, a plug 450 arranged inside the slag discharge cover 440, an auxiliary pressing plate 480 movably installed inside the suspension 420, a second baffle 470 fixedly installed at the port of the suspension 420, and an expansion mask 490 arranged between the second baffle 470 and the auxiliary pressing plate 480;

[0035] The sieve plate 410 is integrally of a U-shaped structure, and evenly distributed discharge slots are provided at the top of the sieve plate 410;

[0036] Chutes are provided inside the end plates at both ends of the suspension 420, and slideways communicating with the chutes are provided at the tops of the end plates at both ends of the suspension 420;

[0037] The sliding plates at both ends of the auxiliary pressing plate 480 are movably installed in the two chutes, and studs are provided at the tops of the sliding plates, and the studs penetrate outside the slideways.

[0038] By starting the motor 250, after the transmission shaft inside the motor 250 rotates, the turntable 260 installed on the transmission shaft will drive the first pull rod 270 to perform eccentric motion, and the second pull rod 280 driven by the first pull rod 270 will drive the guide rod 290 to extend regularly. Finally, the guide rod 290 will drive the suspension 420 and multiple pressing plates 430 to vibrate frequently. At this time, the filter bag 460 after being fully pressurized can accelerate the filtration of the coating under the vibration of the minimum pressure-bearing area;

[0039] The filtered coating will be released outward along the discharge chute 120, and the filter residue will remain inside the filter bag 460. After the water-based coating is completely filtered, the two positioning plates 230 can be taken out, and the plug 450 can be pulled out from the inside of the slag discharge cover 440. Pour clean water from the expansion mask 490. Finally, the filter residue temporarily stored inside the filter bag 460 can be quickly cleaned.

[0040] Example 2: As shown in combination with Figure 2 and Figure 5 Based on Example 1, the angle adjustment mechanism 100 includes a base 110, a shaft rod 130 arranged inside the base 110, two force arms 140 installed at both ends of the shaft rod 130, a first end 150 movably installed inside one of the force arms 140, a second end 160 movably installed on the base 110, and a hydraulic component 170 fixedly installed inside the second end 160;

[0041] A discharge chute 120 is provided at the top of the base 110.

[0042] Preferably, the first end 150 and the second end 160 are respectively installed on a force arm 140 and the base 110 through bearings. After the hydraulic component 170 operates, the internal hydraulic sub-rod will push the first end 150 to extend outward. Finally, the first end 150 will boost the force arm 140 to rotate around the shaft rod 130 as the axis. At this time, the filter press slag discharge mechanism 400 and the stability enhancement protection mechanism 200 clamped by the two force arms 140 can be tilted and lifted, and finally the port of the expansion mask 490 can be lifted upward, so as to facilitate the selective pressure extrusion operation on the filter bag 460.

[0043] Example 3: As shown in combination with Figure 4 and Figure 5 Based on Example 1, the filter bag pressurization mechanism 300 includes a clamping plate 310 arranged on the top of the anti-overflow outer plate 210, two first bolts 320 arranged inside the clamping plate 310, a track plate 330 fixedly installed on the top of the clamping plate 310, a screw rod 340 movably installed inside the track plate 330, a machine base 350 installed at the bottom end of the screw rod 340, a second bolt 360 arranged on the threaded section of the screw rod 340, and a spring 370 arranged outside the screw rod 340.

[0044] By using a wrench to adjust the second bolt 360 until the pressure exerted by the screw rod 340 and its bottom base 350 on the top of the suspension 420, the pressure of two groups of filter bag pressurizing mechanisms 300 evenly distributed at the head and tail ends of the suspension 420 can be selectively regulated. Eventually, the pressure on the head and tail ends of the filter bag 460 will also be regulated;

[0045] At the same time, the four groups of evenly distributed filter bag pressurizing mechanisms 300 can ensure the stability of the high-frequency vibration of the suspension 420 and multiple pressing plates 430.

[0046] The working principle and usage process of the present utility model: First, operate the hydraulic component 170. As the hydraulic sub-rod in the hydraulic component 170 extends outward, the outer end of the hydraulic sub-rod will push the first end 150, the combined shaft rod 130, and the two force arms 140 to turn upward;

[0047] The ends of the two force arms 140 away from the shaft rod 130 will lift the sieve plate 410 to tilt upward. Then, use a wrench to adjust the nuts on the studs at both ends of the auxiliary pressing plate 480 until the auxiliary pressing plate 480 presses tightly on the side of the port of the filter bag 460. Then, the worker can pour the mixed water-based paint along the port of the expansion mask 490 until the water-based paint continuously pours into the filter bag 460. At the same time, start and operate the motor 250. As the transmission shaft inside the motor 250 rotates in cooperation with the turntable 260, the first pull rod 270 and the second pull rod 280 installed on the end rod at the position deviating from the center of the turntable 260 will be pulled to extend reciprocally. Eventually, the entire suspension 420 and multiple pressing plates 430 will be pulled to vibrate at high frequency, and under the downward extrusion of the four groups of filter bag pressurizing mechanisms 300, the multiple evenly distributed pressing plates 430 can extrude the expanded filter bag 460;

[0048] After the filter bag 460 is vibrated at high frequency, the water-based paint can be effectively filtered out, and the filter residue will be temporarily stored inside the filter bag 460. When the water-based paint is completely filtered out, the two positioning plates 230 can be pulled out until the plug 450 is withdrawn from the slag discharge cover 440. Then, the continuously vibrating multiple suspensions 420 can drive out the filter residue inside the filter bag 460;

[0049] After the filter residue is removed, pour the aqueous solution directly into the filter bag 460 along the expansion mask 490, so as to quickly clean the inside of the filter bag 460.

[0050] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
