[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0005] A filter press waste water collection device includes a rectangular box body with a box opening at the top. The two sides of the long side of the box opening are installation sides. An upper box plate and a lower box plate are respectively hinged and installed on the two installation sides. The lengths of the upper box plate and the lower box plate correspond to each other and are longer than the box body. The width of the lower box plate is greater than half of the width of the box opening. The width of the upper box plate is greater than the width of the lower box plate. When the upper box plate swings inward, it is located above the lower box plate. And when the lower box plate swings into the box opening, the maximum swing amplitude is that the inner side edge of the lower box plate is higher than the outer side edge. The outer sides of the upper box plate and the lower box plate respectively have a groove structure.

[0026] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0027] Embodiment 1:

[0028] The present device integrates the facilities for docking and collecting the cleaning waste liquid and the facilities for collecting the filter cake of the plate filter press. By integrating the two necessary requirements and sharing the space below, it is not necessary to hoist the whole machine and move it during the cleaning operation.

[0029] The present device includes a box body 1, the box body 1 adopts a top-open structure, and there is a box opening at the top of the box body 1. The box body 1 and the box opening adopt a rectangular structure and are arranged below the plate filter press. The filter cake is collected through the box opening during the discharging process above. Therefore, the length of the box body 1 is adapted to the length of the plate filter press, and the width is greater than the width of the filter plate.

[0030] Both sides of the long side of the box opening are installation sides, and an upper box plate 2 and a lower box plate 3 are respectively hinged and installed on the two installation sides. The specific structure is as follows:

[0031] The lengths of the upper box plate 2 and the lower box plate 3 correspond to each other and are both longer than the length of the box opening, and can cover the box opening.

[0032] The width of the upper box plate 2 is greater than half of the width of the box opening, and the width of the lower box plate 3 is greater than half of the width of the box opening. Thus, when the upper box plate 2 and the lower box plate 3 swing into the box opening simultaneously based on the hinge, the box opening can be completely blocked.

[0033] On the outer sides of the upper box plate 2 and the lower box plate 3, shaft seats 4 extending downward are respectively fixed in the middle. On both sides of the shaft seat 4, rotating shafts 5 are respectively fixed. At both ends of the installation side, there are shaft sleeves 6 rotatably connected to the rotating shafts 5, realizing the hinged installation of the upper box plate 2 and the lower box plate 3.

[0034] In order to limit the hinged state of the upper box plate 2 and the lower box plate 3 when the box opening is in a closed state and prevent the lower box plate 3 from swinging excessively inward, at both ends of the installation side where the lower box plate 3 is installed, support blocks 7 are respectively provided. On the top surface of the support block 7, there is an inclined surface. The inclined surface slopes upward from the installation side into the box opening. The inclined surface is used to contact and support the bottom surface of the lower box plate 3. When the bottom surface of the lower box plate 3 falls on the inclined surface, the lower box plate 3 is inclined in the same direction as the inclined surface, and the bottom surface of the upper box plate 2 abuts against the top side of the lower box plate 3. Thus, the lower box plate 3 is supported by the support block 7, and the upper box plate 2 is supported by the inner side edge of the lower box plate 3, forming a triangular structure with the central docking part arched upward for the lower box plate 3 and the upper box plate 2. If wastewater falls from above, it can be diverted to both sides under this structure.

[0035] Not limited to this example, in order to improve stability, support blocks 7 can also be provided at both ends of both installation sides. The top surface of the support block 7 is also provided with an inclined surface sloping upward from the outside to the inside. Thus, the lower box plate 3 and the upper box plate 2 are respectively supported by the support blocks 7 on both sides. And when the lower box plate 3 and the upper box plate 2 respectively abut against the support blocks 7 on the same side, the bottom surface of the upper box plate 2 is in contact with the top side edge of the lower box plate 3.

[0036] The width of the upper box plate 2 is larger than that of the lower box plate 3, so that when the box opening is closed, the top side of the upper box plate 2 covers the joint position where the two meet. When wastewater falls, there is no joint to prevent leakage, ensuring that the wastewater is diverted to both sides. For further diversion, on the inner side edge of the upper box plate 2, there is also a folded plate 8 bent downward. The folded plate 8 and the upper box plate 2 (when the upper box plate 2 falls on the support block 7) can form a triangular structure for diversion to both sides, further improving the diversion effect and preventing the water flow from flowing downward along the upper side of the upper box plate 2.

[0037] On the outer sides of the upper box plate 2 and the lower box plate 3 that are far away from each other, there are respectively fixed connecting plates 9. The connecting plates 9 respectively form an angle of 120 degrees with the upper box plate 2 and the lower box plate 3.

[0038] The folded plate 8 - upper box plate 2 - connecting plate 9, and the lower box plate 3 - connecting plate 9 can respectively be obtained by sheet metal bending of metal sheet materials. Not limited to this example, they can also be obtained by welding and fixing equal-length metal plates. Not limited to this example, other angles between 110 - 140 degrees can also be used for bending.

[0039] The upper box board 2 is provided with a first side baffle 10 on both sides, and the lower box board 3 is provided with a second side baffle 11 on both sides. The first side baffle 10 is a triangular plate, and its two sides are respectively connected to one side of the wide side of the upper box board 2 and the side of the pocket board 9 on the same side. The second side baffle 11 is also a triangular plate, and its two sides are respectively connected to one side of the wide side of the lower box board 3 and the side of the pocket board 9 on the same side.

[0040] A triangular trough structure for temporarily accommodating and receiving wastewater is formed by the pocket plate 9, the first side baffle 10 and the upper box plate 2. A triangular trough structure for temporarily accommodating and receiving wastewater is formed by the pocket plate 9, the second side baffle 11 and the lower box plate 3. The fallen wastewater is collected and temporarily stored by the trough structure located on both sides above the box mouth, and a guide pipe 12 is provided on one of the first side baffles 10 and the second side baffle 11. The guide pipe 12 is connected to a water pipe for draining and collecting wastewater.

[0041] Based on the above structure, the upper box plate 2 can be opened manually or by other external force, and the upper box plate 2 and the lower box plate 3 are respectively pressed against the side wall of the box body 1 by the folding plate 8, so that the upper box plate 2 and the lower box plate 3 are opened outward. Based on the folding angle of 120 degrees between the folding plate 8 and the upper box plate 2 and the lower box plate 3, the upper box plate 2 and the lower box plate 3 are respectively opened outward into an outward-extended trumpet-shaped state, thereby greatly expanding the range for receiving filter cakes. Even if the box opening is not obviously wider than the filter disc, the scattered filter cakes can be well caught, and when the upper box plate 2 and the lower box plate 3 are flipped inward and closed, the filter cake fragments that fall on the box plate are flipped and incorporated into the box body 1. Through the very practical and simple structure, a very effective function of expanding the space for receiving filter cakes is achieved, saving space in the workshop.

[0042] When flushing the filter disc, the upper box plate 2 and the lower box plate 3 are flipped relative to each other to close the box opening, and the falling cleaning wastewater is guided into the trough structure on both sides through the inclined and triangular structure of the upper box plate 2 / lower box plate 3, and is thus collected.

[0043] The device realizes the rational use of space through a simple structure, and can expand the receiving range when receiving filter cakes, divert and collect filter press wastewater during flushing, simplifying the filter press operation and improving operating efficiency.

[0044] Example 2:

[0045] In this example, the flipping of the upper box plate 2 and the lower box plate 3 can be electrically controlled. A first upper pulley is fixed to one end of the rotating shaft 5 of the upper box plate 2, and a second upper pulley is fixed to one end of the rotating shaft 5 of the lower box plate 3.

[0046] On the middle part of one side of the box body 1 close to the first pulley 13 and the second pulley 14, a first lower pulley 15 and a second lower pulley 16 are rotatably installed. The first lower pulley 15 and the second lower pulley 16 are arranged side by side left and right. A first gear is coaxially fixed on the axle of the first lower pulley 15, and a second gear is coaxially fixed on the axle of the second lower pulley 16. The first gear and the second gear are meshed. A transmission belt is provided between the first pulley 13 and the first lower pulley 15, and a transmission belt is provided between the second pulley 14 and the second lower pulley 16. The first lower pulley 15 is driven by a motor, so as to realize the synchronous reverse rotation control of the two side rotating shafts 5, and realize the opening or closing operation of the electric flip-up upper box plate 2 and the lower box plate 3, further saving manpower.
