Description

Technical Field

[0001] The present application relates to the technical field of ceramic filters, and in particular to a quickly adjustable anti-collision scraper for a filter. Background Art

[0002] The ceramic filter works on the principle of capillary pores and uses microporous ceramics as the filter medium. During the use of the ceramic filter, the fan-shaped filter plate will deviate, and the deflection at the root of the filter plate is smaller than the deflection at the outer edge of the filter plate.

[0003] The quick-adjustable anti-collision scraper system of the filter usually consists of a scraper, a scraper frame, and fixing bolts. Among them, the scraper is a key component, which is used to scrape the filter cake adsorbed on the surface of the ceramic filter plate. The scraper is set in the interval formed by the cover plate and the fixed plate, and the side of the scraper in contact with the ceramic plate is covered on the fixed plate, and the side of the scraper falling is covered on the cover plate. The cover plate is fixed to the fixed plate by a clamping bolt. At the same time, the limit block and clamping bolts are used to ensure the stability and accuracy of the scraper during work.

[0004] When a conventional quick-adjustable filter anti-collision scraper is installed, the blade is usually aligned horizontally with the edge of the filter plate spacing. However, when the filter plate is seriously offset, the edge of the filter plate spacing will collide with the blade, causing damage to the filter plate. Summary of the invention

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a quickly adjustable anti-collision scraper for a filter.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A quickly adjustable anti-collision scraper for a filter, comprising a filter plate, wherein the quickly adjustable anti-collision scraper for a filter also comprises:

[0008] Fixings;

[0009] A movable part hinged to a fixed part;

[0010] A blade is arranged on the movable part, and an angle is formed between the blade edge and the side surface of the filter plate, and the angle range is 0 to 90 degrees;

[0011] The height of one end of the blade close to the filter plate root is greater than the height of the other end of the blade close to the outer edge of the filter plate, so that when the filter plate deviates, the end of the blade close to the filter plate root first contacts the part of the filter plate root with smaller displacement change.

[0012] Optionally, the fixing member is fixed to the filter base by means of hexagonal bolts.

[0013] Optionally, the lower end of the fixing member is hinged to the movable member via a pin.

[0014] Optionally, the blade is connected to an end of the movable member away from the pin through a mounting plate.

[0015] Optionally, the mounting plate is connected to the blade via countersunk screws.

[0016] Optionally, the movable part is provided with an adjusting bolt and an adjusting nut.

[0017] Optionally, the adjusting bolt and the adjusting nut are respectively a butterfly bolt and a butterfly nut.

[0018] Optionally, the blade is made of ultra-high molecular weight polyethylene plate.

[0019] Beneficial effects of the present application: In the present application, the fixed part and the movable part are hinged, so that the angle between the two can be changed conveniently to adjust the gap between the blade and the filter plate. The blade is arranged on the movable part, and the height of the end of the blade near the root of the filter plate is greater than the height of the end of the blade near the outer edge of the filter plate, that is, the traditional horizontal installation of the blade is adjusted to an inclined installation with the inside higher and the outside lower. The inner side of the blade near the main shaft is higher, and it first scrapes the part of the root of the filter plate with a smaller displacement change, so that the blade and the edge of the filter plate interval change from line contact during horizontal installation to point contact during inclined installation, so as to avoid the blade pressing against the filter plate and causing damage to the filter plate.

[0032] The above description is only an optional embodiment of the present application and is not intended to limit the present application.

[0033] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0034] Embodiment 1:

[0035] See also Figure 1 and Figure 2 A quick-adjustable anti-collision scraper for a filter comprises a filter plate 4, and the quick-adjustable anti-collision scraper for a filter further comprises:

[0036] Fixing part 1;

[0037] A movable member 2 hinged to the fixed member 1;

[0038] A blade 3 is arranged on the movable part 2, and an angle is formed between the blade edge of the blade 3 and the side surface of the filter plate 4, and the angle range is 0-90°;

[0039] The height of one end of the blade close to the root of the filter plate 4 is greater than the height of the other end of the blade close to the outer edge of the filter plate 4, so that when the filter plate 4 is offset, the end of the blade close to the root of the filter plate 4 first contacts the part of the root of the filter plate 4 with smaller displacement change.

[0040] Specifically, the fixing part 1 is installed on the filter base 6, and above the filter base 6 is a disc-shaped ceramic filter plate 4, and there is a gap between adjacent filter plates 4. When a traditional quick-adjustable filter anti-collision scraper is installed, the blade is usually horizontally aligned with the edge of the gap between the filter plates 4. However, when the filter plate 4 is seriously offset, the edge of the gap between the filter plate 4 will align and collide with the blade, thereby causing damage to the filter plate 4.

[0041] In the present application, the fixed part 1 is hinged with the movable part 2, so that the angle between the two can be changed conveniently to adjust the gap between the blade 3 and the filter plate 4. The blade 3 is arranged on the movable part 2, and the blade 3 has an angle of 0 to 90 degrees with the side surface of the filter plate 4, so that the blade can cut into the material more smoothly and reduce energy loss. The height of the end of the blade close to the root of the filter plate 4 is greater than the height of the end of the blade close to the outer edge of the filter plate 4, that is, the traditional horizontal installation method of the blade is adjusted to an inclined installation method with the inside high and the outside low. The inner side of the blade close to the main shaft is higher, and it first scrapes the part of the root of the filter plate 4 with a smaller displacement change, so that the edge of the interval between the blade and the filter plate 4 changes from line contact during horizontal installation to point contact during inclined installation, so as to avoid the blade 3 pressing against the filter plate 4 and causing damage to the filter plate 4.

[0042] Embodiment 2:

[0043] See also Figures 1 to 3 Based on the first embodiment, optionally, the fixing member 1 is fixed to the filter base 6 by a hexagonal bolt 5 .

[0044] Specifically, the hexagonal head of the hexagonal bolt 5 is easily clamped by a wrench or a screwdriver, which facilitates the installation and removal of the fixing member 1. In addition, the head design of the hexagonal bolt 5 can provide better self-locking performance, and the fixing member 1 is not easy to loosen even in a vibration or impact environment.

[0045] Optionally, the lower end of the fixing member 1 is hinged to the movable member 2 via a pin 7 .

[0046] Specifically, the fixed part 1 and the movable part 2 form a mechanism similar to a hinge structure through the pin shaft 7. Such an arrangement facilitates driving the movable part 2 to adjust the angle.

[0047] Optionally, the blade 3 is connected to an end of the movable member 2 away from the pin 7 via a mounting plate 8 .

[0048] Specifically, the end of the movable member 2 away from the pin 7 is fixedly connected to the lower end surface of the mounting plate 8, and the upper end surface of the mounting plate 8 is detachably connected to the lower end surface of the blade 3, and the end surfaces of the two are in contact with each other. The fixed member 1, the movable member 2, the pin 7, and the mounting plate 8 constitute a scraper bracket for supporting the blade 3.

[0049] Optionally, the mounting plate 8 is connected to the blade 3 via a countersunk screw 9 .

[0050] Specifically, the mounting plate 8 is detachably connected to the blade 3 via four countersunk screws 9, which facilitates the installation and removal of the blade 3. At the same time, the heads of the countersunk screws 9 can sink to be flush with the larger surface, thereby improving the flatness of the surface of the blade 3.

[0051] Optionally, the movable part 2 is provided with an adjusting bolt 10 and an adjusting nut 11 .

[0052] Specifically, in order to prevent the gap between the blade 3 and the filter plate 4 from being too small and to enable it to maintain a set distance from the blade 3, a positioning and locking adjusting bolt 10 is provided at one end of the movable part 2 close to the root of the filter plate 4, and the gap positioning between the blade 3 and the filter plate 4 is achieved by adjusting the bolt 10.

[0053] Optionally, the adjusting bolt 10 and the adjusting nut 11 are respectively a butterfly bolt and a butterfly nut.

[0054] Specifically, the head of the butterfly nut is designed in a butterfly shape, and this wide head provides a better grip. Compared with traditional bolts, butterfly bolts and butterfly nuts can be easily rotated without the use of tools, which greatly improves the convenience of operation. It is very suitable for occasions that require frequent adjustment or fine-tuning.

[0055] Optionally, the blade 3 is made of ultra-high molecular weight polyethylene plate.

[0056] Specifically, the ultra-high molecular weight polyethylene plate is an engineering plastic material that is softer than the ceramic filter plate 4 , is resistant to acid and alkali corrosion and wear, has low cost, does not wear the ceramic filter plate 4 , and avoids damage to the surface of the filter plate 4 .

[0057] In this embodiment, in order to improve the adjustment speed and accuracy and reduce the difficulty of operation, the fixed part 1, the movable part 2, and the mounting plate 8 are designed into a scraper bracket with a hinge structure through the pin shaft 7. By loosening and tightening the butterfly bolt and butterfly nut, the gap between the blade 3 and the filter plate 4 can be quickly adjusted and accurately fine-tuned. The adjustment process does not require tools such as wrenches. The adjustment nut 11 is hidden under the scraper bracket to avoid ore accumulation and does not contact the blade part, thereby improving the convenience of operation.

[0058] It should be noted that structures and / or installation methods not described in detail in this application are known to those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of disclosure in this application and will not be further elaborated herein.

[0059] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
