Description

Technical Field

[0001] This utility model belongs to the field of automation technology of pressure filtration equipment in solid-liquid separation process, and relates to an automatic plate unloading filter press. Background Technology

[0002] A filter press is a general-purpose solid-liquid separation and filtration device. The general workflow of an automatic filter press is as follows: the solid-liquid mixture is pressurized and conveyed to the filter chambers by a feed pump. The filter cloth traps particles in the material to form a filter cake, and the filtrate is discharged from the filter chamber. A pressing pump then presses the diaphragm filter plates to squeeze and dehydrate the filter cake, and the filtrate is discharged from the filter chamber. Compressed air is injected into each filter chamber to dry and dehydrate the filter cake, and the filtrate is discharged from the filter chamber. A plate-pulling mechanism pulls open the filter plates, achieving gravity-fed cake discharge. This intermittent reciprocating cycle achieves batch solid-liquid separation. An automatic filter press mainly consists of a frame and pressing mechanism, a filtration mechanism, a plate-pulling mechanism, a hydraulic drive mechanism, and an electrical control system. The filter plates are arranged and installed on the main beam of the frame. The plate-pulling mechanism's trolley moves back and forth on the plate-pulling track, automatically separating adjacent filter plates (opening the filter chamber), and the filter cake automatically falls off under gravity.

[0003] The automatic filter press's plate-pulling mechanism mainly consists of a plate-pulling motor, a transmission chain, a plate-pulling track, a plate-pulling trolley, a pressing and returning frame, a pin return frame, a linkage long shaft, an adjusting short shaft, and gears. The plate-pulling track is located on the main beams on both sides of the filter press. Driven by the plate-pulling motor and connected by the transmission chain, the plate-pulling trolley moves along the track. The robotic arm on the trolley (including a plate-grabbing crank and a plate-pulling inclined rod) can move back and forth with the trolley to grab and release the filter plate handles, achieving reciprocating plate-pulling. The pressing and returning frame is located at the filter press's feed end on the main beam. Its function is to contact the trolley after unloading, pressing down the plate-pulling inclined rod and inserting the pin into the bottom of the inclined rod, allowing the trolley to smoothly return to the cylinder end. The pin return frame is located at the filter press's cylinder end on the main beam. Its function is to remove and reset the pin inserted into the bottom of the inclined rod after the trolley contacts it.

[0004] The plate-pulling trolley consists of a plate-pulling base, a plate-pulling body, a robotic arm, a sleeve and pin device, wear-resistant blocks, springs, and other parts. The robotic arm is divided into a plate-grabbing curved rod and a plate-pulling inclined rod. A spring is installed at the bottom of the robotic arm so that it can be pressed down and then spring back to its original position. When the robotic arm is not pressed down, it can grasp the filter plate; when pressed down, it can release the filter plate. The sleeve and pin device consists of a pin, a pin sleeve, a pin rod, and a mounting plate. The external thread of the pin rod corresponds to the internal thread on the pin. The pin rod is tightened onto the pin, and the pin can move within the pin sleeve. When the pin is inserted into the bottom of the plate-pulling inclined rod, it keeps the plate-pulling inclined rod pressed down; conversely, when the pin is pulled out, the plate-pulling inclined rod returns to its original position.

[0005] The existing sleeve pin devices of the plate pulling trolley have the following defects: When the plate pulling trolley moves on the plate pulling track, it collides with the pressing return frame and the pin return frame at the feed end and the cylinder end of the filter press, respectively. In principle, the pin of the sleeve pin device should not have a strong impact on the pressing return frame or the pin return frame. However, if the pressing return frame or the pin return frame is loose or damaged, it will cause the pin to exceed the bearing capacity when it contacts the pressing return frame or the pin return frame, causing the pin to bend or its external thread to break in the pin, affecting the normal use of the plate pulling trolley and affecting the performance and efficiency of the filter press. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of existing sleeve pin devices, solve the corresponding technical problems, and provide a reinforced sleeve pin device for pull plate trolleys.

[0007] The technical solution adopted by this utility model to solve the existing technical problems is: a reinforced sleeve pin device for a plate-pulling trolley, mainly composed of six parts: a pin, a pin sleeve, a pin rod, a right-angle reinforcing plate, a fixing bolt, and a mounting block. Compared with the existing sleeve pin device, its distinguishing feature is that a bolt hole for mounting the fixing bolt is added to the rear end of the pin, and a right-angle reinforcing plate is added. One end of the right-angle reinforcing plate is connected to the pin rod, and the other end is fixed to the pin with a fixing bolt. The right-angle reinforcing plate is made of stainless steel and is located between the pin rod and the pin, playing a role similar to triangular stability. Under the action of the right-angle reinforcing plate, the pin rod is more stable, more impact-resistant, and less prone to deformation, extending the service life of the pin and improving the efficiency of the filter press.

[0008] Furthermore, the pin is made of cylindrical steel with an outer diameter of 14mm and a length of 65mm. The pin has a threaded rod hole for installation with the pin rod. One end of the pin has a threaded bolt hole with an inner diameter of 6mm for installing a fixing bolt. The other end has a hemispherical structure to facilitate the insertion of the pin into the bottom of the pull plate diagonal rod.

[0009] Furthermore, the pin sleeve is made of cylindrical steel with an inner diameter of 16mm and a length of 40mm. It has a sliding elongated hole. The pin is placed in the pin sleeve, and the pin rod passes through the sliding elongated hole of the pin sleeve and is installed on the pin. The sliding elongated hole of the pin sleeve meets the effective stroke of the pin and ensures that the pin will not come out of the pin sleeve.

[0010] Furthermore, the right-angle reinforcing plate is a right-angle structure made of stainless steel, with small holes at both ends for the pin and fixing bolt to pass through, respectively. It connects the pin and the bolt, providing reinforcement and stability, making the pin less prone to deformation upon impact.

[0011] Furthermore, the pin is a cylindrical rod with an outer diameter of 5mm, one end of which is provided with an external thread. This threaded end is installed in the rod hole on the pin, and the other end is machined into a flat shape to facilitate the installation and removal of the pin using a wrench.

[0012] Furthermore, the fixing bolt, which is an M6×15 internal hex bolt, is installed in the bolt hole of the pin. The fixing bolt can pass through the corresponding round hole of the right-angle reinforcing plate to fix the right-angle reinforcing plate to the pin.

[0013] Furthermore, the mounting block is trapezoidal in shape and is welded to the pin sleeve, and also welded to the side of the puller body of the puller trolley, thus fixing the reinforced sleeve pin device as a whole onto the puller trolley.

[0014] The reinforced sleeve pin device for the plate pulling trolley provided by this utility model has the advantages of simple structure, convenient assembly, strong and reliable, and high stability. It not only extends the service life of the pin and pin rod and reduces the failure rate of the plate pulling system, but also improves the reliability of automatic plate pulling, ensures automatic continuous production of the filter press, and improves production efficiency.

Detailed Implementation

[0026] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the reinforced sleeve pin device for the pull-plate trolley. The described embodiments are only a part of the preferred embodiments of the present invention, and not all of the embodiments. All other embodiments without inventiveness that are made by those skilled in the art based on the embodiments of the present invention are within the protection scope of the present invention. Example

[0027] A reinforced sleeve pin device 10 for a pull-plate trolley mainly consists of six parts: a pin 1, a pin sleeve 2, a pin 3, a right-angle reinforcing plate 4, a fixing bolt 5, and a mounting block 6. The pin 1 has a threaded bolt hole 8 and a rod hole 7 for mounting the fixing bolt 5 and pin 3, respectively. The pin 1 is placed in the pin sleeve 2. The fixing bolt 5 passes through the corresponding small hole on the right-angle reinforcing plate 4 and is installed in the bolt hole 8 of the pin 1. The threaded end of the pin 3 passes through the corresponding small hole on the right-angle reinforcing plate 4 and the sliding elongated hole 9 on the pin sleeve 2 and is installed in the rod hole 7 of the pin 1. The mounting block 6 is welded to the bottom of the pin sleeve 2. When the pull-plate trolley 15 contacts the overturning return frame 13 or the pin return frame 14 during movement, the pulling or pushing force acts on the pin 3, causing the pin 3 to slide in the sliding elongated hole 9 of the pin sleeve 2, simultaneously causing the pin 1 to slide in the pin sleeve 2.

[0028] Furthermore, the pin 1 is made of cylindrical steel with an outer diameter of 14mm and a length of 65mm. The pin 1 is provided with a rod hole 7 with internal threads for installation with the pin 3. One end of the pin 1 is also provided with a bolt hole 8 with internal threads. The bolt hole 8 has an inner diameter of 6mm for installing the fixing bolt 5. The other end of the pin 1 has a hemispherical structure to facilitate the insertion of the pin 1 into the bottom of the pull plate inclined rod 12.

[0029] Furthermore, the pin sleeve 2 is made of cylindrical steel with an inner diameter of 16mm and a length of 40mm. It is provided with a sliding elongated hole 9. The pin 1 is placed in the pin sleeve 2. The pin rod 1 can be installed on the pin 1 by passing through the sliding elongated hole 9 of the pin sleeve 2. The sliding elongated hole 9 of the pin sleeve 2 meets the effective stroke of the pin 1 and at the same time ensures that the pin 1 will not come out of the pin sleeve 2.

[0030] Furthermore, the pin 3 is a cylindrical rod with an outer diameter of 5mm. One end of the pin is provided with an external thread, which is installed in the rod hole 7 on the pin 1. The other end is machined into a flat shape to facilitate the installation and removal of the pin 3 using a wrench.

[0031] Furthermore, the right-angle reinforcing plate 4 is a right-angle structure made of stainless steel, with small holes at both ends for the pin 3 and the fixing bolt 5 to pass through, respectively. It connects the pin 3 and the pin 1, serving to strengthen stability and prevent the pin 3 from easily deforming upon impact.

[0032] Furthermore, the fixing bolt 5, which is an M6×15 internal hex bolt, is installed in the bolt hole 8 of the pin 1. The fixing bolt 5 can pass through the corresponding round hole of the right-angle reinforcing plate 4 to fix the right-angle reinforcing plate 4 to the pin 1.

[0033] Furthermore, the mounting block 5 is trapezoidal in shape and is welded to the pin sleeve 2. It is also welded to the side of the puller body 11 of the puller trolley 15, thus fixing the reinforced sleeve pin device 10 as a whole onto the puller trolley 15. Example

[0034] An automatic plate-pulling filter press is composed of a frame and a pressing mechanism, a filtering mechanism, a plate-pulling mechanism, a hydraulic drive mechanism, an electrical control system, etc. The plate-pulling trolley 15 of the plate-pulling mechanism is equipped with a reinforced sleeve pin device 10 for the plate-pulling trolley as described in Example 1. When the automatic plate-pulling filter press begins unloading, the plate-pulling trolley 15 starts pulling apart the first filter plate 17 from the cylinder end of the filter press, one by one. The mechanical arm of the plate-pulling trolley 15 is equipped with springs that automatically grab and release the filter plates 17. The plate-pulling trolley 15 moves back and forth on the plate-pulling track 16 to achieve the automatic plate-pulling and unloading process. After the plate-pulling trolley 15 has pulled apart all the filter plates 17, it continues to move and contacts the pressing return frame 13 at the feed end of the filter press. The pressing return frame 13 will press down the plate-pulling inclined rod 12 of the plate-pulling trolley 15, and simultaneously push the pin 3 of the reinforced sleeve pin device 10 to push the pin 1 into the bottom of the plate-pulling inclined rod 12, preventing the plate-pulling inclined rod 12 from springing back to its original position. Figure 8As shown, this ensures that the plate-pulling trolley 15 can return to the oil cylinder end of the filter press. When the plate-pulling trolley 15 returns to the oil cylinder end, it will contact the pin return frame 14 at its end. The pin return frame 14 can act on the pin 3 of the reinforced sleeve pin device 10 for the plate-pulling trolley, causing the pin 1 to be pulled out at the bottom of the plate-pulling inclined rod 12, as shown. Figure 9 As shown, this facilitates automatic unloading for the next time.

[0035] The reinforced sleeve pin device 10 for the plate pulling trolley provided by this utility model enhances the installation and fixing strength of the pin 3, making the pin 3 less prone to deformation after colliding with the pressing return frame 13 and the pin return frame 14. This avoids bending deformation or breakage of the pin 3 due to impact, improves the continuity and stability of the plate pulling mechanism, reduces the failure rate, and improves the production efficiency of the filter press.
