Description

Technical Field

[0001] The utility model belongs to the technical field of viscous fluid filtering, in particular to a filter for producing high-viscosity coupling agents. Background Art

[0002] In plastic compounding, coupling agent is a plastic additive that improves the interfacial properties between synthetic resin and inorganic filler or reinforcing material, also known as surface modifier. It can reduce the viscosity of synthetic resin melt during plastic processing, improve the dispersion of filler to improve processing performance, and thus make the product obtain good surface quality and mechanical, thermal and electrical properties. It is used in silicone sealant, polyurethane adhesive, silicon powder, electronic plastic sealing material, glass fiber, synthetic insulator and other industries.

[0003] However, in production, solid foreign matter often exists in the liquid coupling agent and needs to be filtered. In the existing filtration technology, unlike conventional liquids or fixed particles, due to the high viscosity of the coupling agent, the filtration efficiency of the adopted filtration structure is slow and it is easy to be damaged after long-term use. Therefore, how to filter the coupling agent efficiently, quickly, safely and reliably has become a technical problem that this solution focuses on solving. Utility Model Content

Different from the previous filtering ideas, the present invention involves passing a lifting plate through a filter plate, and a large amount of coupling agents are bonded to the side of the lifting plate in a containing tube. The coupling agents on the lifting plate are scraped off by the scraping action of a scraper, and the filtering efficiency is relatively high. More importantly, the filter plate is not easily damaged, and the service life is increased.

[0006] The filter plate is provided with a plurality of long through holes arranged in parallel with each other, the lifting plate passes through the long through holes, and gaps are respectively provided between the two sides of the lifting plate and the two sides of the long through holes.

[0007] The scraping mechanism includes a plurality of horizontally arranged rotating shafts, a scraper arranged on the side of the rotating shaft, and a power mechanism for driving the plurality of rotating shafts to rotate simultaneously. The rotating shaft is arranged between two adjacent lifting plates, the width of the scraper is consistent with the distance between two adjacent lifting plates, and the two ends of the rotating shaft are respectively hinged on the two sides of the receiving box.

[0008] The power mechanism includes a gear arranged at the end of the rotating shaft, a gear rod connected to several of the gears at the same time, and a cylinder connected to one end of the gear rod. The two ends of the gear rod pass through two slide blocks respectively, and the two slide blocks are connected to the receiving box. The gear, the gear rod, the slide block and the cylinder are all arranged outside the receiving box.

[0009] The lifting plate is corrugated, the outer side of the scraper is serrated, and the outer side of the horizontally arranged scraper is matched with the outer side of the lifting plate.

[0010] The up and down driving mechanism includes a horizontal plate connected to the plurality of lifting plates, a conical block whose bottom surface is connected to the upper end surface of the horizontal plate, a lifting column which is vertically arranged and whose bottom end is connected to the tip of the conical block, and an eccentric column whose one end is hingedly connected to the top of the lifting column, and the other end of the eccentric column is hingedly connected to the edge of a driving disk, and the driving disk is vertically arranged and connected to a motor via a driving shaft passing through the center thereof.

[0015] The utility model achieves the following significant effects:

[0016] (1) A filter plate and a lifting plate are provided. The lifting plate passes through the filter plate. Since there is a large amount of liquid coupling agent in the accommodating cylinder, the lifting plate moves upward, and a large amount of coupling agent is adhered to its surface. Then it moves downward, and the coupling agent is brought into the receiving box. There is a gap between the lifting plate and the long through-holes on the filter plate, which can well block solid foreign matter. The transfer process of the coupling agent is completed by using mechanical power, which greatly improves the filtration efficiency. At the same time, the filter plate plays a blocking role, which helps to protect the filter plate;

[0017] (2) A scraping mechanism is provided, and the coupling agent on the lifting plate is scraped off by the scraper, and the liquid coupling agent falls into the receiving box, completing the collection process of the coupling agent. Under the action of the PLC control program, after the lifting plate reaches the lowest point, the scraper rotates under the action of the rotating shaft and contacts the side of the lifting plate, the lifting plate rises, and the coupling agent is immediately scraped off, which is convenient and quick;

[0018] (3) The lifting plate is configured to be corrugated in order to increase the contact area with the coupling agent, which can help bring more coupling agents into the receiving box at one time, greatly improving the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0028] Example 1

[0029] See also Figure 1A filter for producing high-viscosity coupling agents comprises a containing cylinder 1 with openings at the upper and lower ends, a receiving box 4 with an opening at the top and a closing at the bottom, a filter plate 8-3 horizontally arranged at the opening position at the top of the receiving box 4, a plurality of lifting plates 8-4 vertically passing through the filter plate 8-3, and a scraping mechanism arranged below the filter plate 8-3 and in contact with the side surfaces of the plurality of lifting plates 8-4. The top ends of the plurality of lifting plates 8-4 are connected to an up-and-down driving mechanism, and the up-and-down driving mechanism is arranged above the containing cylinder 1. The upper end surface of the filter plate 8-3 is an inclined surface.

[0030] The filter plate 8-3 is provided with a plurality of long through holes arranged in parallel with each other, and the lifting plate 8-4 passes through the long through holes, and gaps are respectively provided on both sides of the lifting plate 8-4 and the two sides of the long through holes.

[0031] The upper end surface of the filter plate 8-3 is an inclined surface. When there are a lot of solid foreign matter between the conical block 8-2 and the filter plate 8-3, the solid foreign matter can slide downward along the inclined surface and break away from the filter plate 8-3, avoiding the situation where the lifting and lowering is blocked due to the solid foreign matter being located between the lifting plates 8-4; the filter plate 8-3 structure in the accompanying drawing is only for schematic illustration, and the final interpretation shall be subject to the text description.

[0032] This gap ensures that the coupling agent is bonded to the lifting plate 8 - 4 and brought into the receiving box 4 , while also preventing solid foreign matter from entering the receiving box 4 .

[0033] See also Figure 3 The scraping mechanism includes a plurality of horizontally arranged rotating shafts 2-3, a scraper 2-4 arranged on the side of the rotating shaft 2-3, and a power mechanism for driving the plurality of rotating shafts 2-3 to rotate simultaneously. The rotating shaft 2-3 is arranged between two adjacent lifting plates 8-4. The width of the scraper 2-4 is consistent with the distance between two adjacent lifting plates 8-4. The two ends of the rotating shaft 2-3 are respectively hinged on the two sides of the receiving box 4.

[0034] Preferably, the scraper 2-4 can be made of rubber material, which has a certain flexibility and a larger operating space, and the lifting plate 8-4 can be made of thin steel sheet.

[0035] The power mechanism includes a gear 2-1 arranged at the end of the rotating shaft 2-3, a gear rod 2 connected to several gears 2-1 at the same time, and a cylinder 2-2 connected to one end of the gear rod 2. The two ends of the gear rod 2 pass through two slide blocks respectively, and the two slide blocks are connected to the receiving box 4. The gear 2-1, the gear rod 2, the slide block and the cylinder 2-2 are all arranged outside the receiving box 4.

[0036] Through the action of the cylinder 2-2, the gear rod 2 is driven to move back and forth in a straight line, and the gear rod 2 is meshed with a plurality of gears 2-1, and at the same time, the gears 2-1 are driven to rotate, thereby driving the rotation of the rotating shaft 2-3 and the scraper 2-4, thereby realizing the separation and contact of the scraper 2-4 and the side of the lifting plate 8-4; at the same time, more preferably, the outer side surface of the outermost lifting plate 8-4 is also provided with a rotating shaft 2-3 and a scraper 2-4.

[0037] See also Figure 2 and Figure 3 The up and down driving mechanism includes a horizontal plate 8-41 connected to a plurality of lifting plates 8-4, a conical block 8-2 whose bottom surface is connected to the upper end surface of the horizontal plate 8-41, a lifting column 8-1 which is vertically arranged and whose bottom end is connected to the tip of the conical block 8-2, and an eccentric column whose one end is hingedly connected to the top of the lifting column 8-1, and the other end of the eccentric column is hingedly connected to the edge position of the driving disk 7. The driving disk 7 is vertically arranged and connected to the motor 6 through a driving shaft passing through the center thereof.

[0038] The up and down driving mechanism is essentially a crank slider mechanism, which is easy to implement in the prior art and will not be described in detail here.

[0039] A top cover 5 is provided at the top of the accommodating cylinder 1 , and a lifting column 8 - 1 movably passes through the top cover 5 . A feed pipe 9 is also provided on the top cover 5 , and a discharge pipe 4 - 1 is provided at the bottom of the receiving box 4 .

[0040] See also Figure 7 A heating element 5 - 1 is provided at the lower end of the top cover 5 .

[0041] The PLC controller is also included, and the PLC controller is connected to the scraping mechanism and the upper and lower driving mechanism. The PLC controller substantially controls the operation of the motor 6 and the cylinder 2-2.

[0042] The bottom end of the receiving box 4 is provided with a support leg 3 to play a supporting role.

[0043] The specific working process of this utility model:

[0044] See also Figure 4 , the coupling agent is poured into the accommodating cylinder 1 through the feed pipe 9, the coupling agent falls on the conical block 8-2, and gradually enters the gap between the filter plate 8-3 and the lifting plate 8-4, and falls downward from the gap along the outer side of the lifting plate 8-4. Specifically, since a very small gap is provided on the filter plate 8-3, it is sufficient to block solid foreign matter, so that the solid foreign matter is blocked above the filter plate 8-3, thereby playing a filtering role.

[0045] Since the filter plate 8-3 is provided with a long through hole, the lifting plate 8-4 vertically passes through the long through hole, and there is a gap between the lifting plate 8-4 and the long through hole, the lifting plate 8-4 will inevitably shake left and right during the up and down movement. The shaking action promotes the downward flow of the coupling agent. Since the gap is small, it is enough to block solid foreign matter and prevent solid foreign matter from falling from the gap, thereby achieving the filtering effect. For viscous fluids, this dynamic filtration method has achieved good results.

[0046] Start the up and down driving mechanism to make the lifting plate 8-4 move up and down. Since the coupling agent has adhesiveness, the side of the lifting plate 8-4 is covered with the coupling agent and gradually brought into the receiving box 4. During the descent of the lifting plate 8-4, under the action of the PLC controller, the scraper 2-4 is in a vertical state. After a certain period of time, under the action of the cylinder 2-2, the gears 2-1 are driven to rotate 90 degrees through the movement of the gear rod 2, so that the scraper 2-4 is in a horizontal state. At this time, the two ends of the scraper 2-4 are in contact with the outer side surfaces of the two adjacent lifting plates 8-4 respectively. During the up and down movement of the lifting plate 8-4, the scraper 2-4 scrapes off the coupling agent on the lifting plate 8-4;

[0047] Specifically, when the lifting plate 8-4 moves downward, the scraper 2-4 is in a vertical state; when the lifting plate 8-4 moves upward, the scraper 2-4 is in a horizontal state, which makes it more convenient to scrape off the coupling agent in the lifting plate 8-4.

[0048] Example 2

[0049] See also Figure 5 and Figure 6 The lifting plate 8-4 is corrugated, the outer side of the scraper 2-4 is serrated, and the outer side of the horizontally arranged scraper 2-4 fits with the outer side of the lifting plate 8-4; the corrugated lifting plate 8-4 helps to increase the contact area between the coupling agent and the lifting plate and speed up the filtering efficiency. Correspondingly, a serrated gap is also provided on the filter plate 8-3.

[0050] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
