Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a novel filter. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, filters are crucial equipment for solid-liquid separation, and their performance directly affects production efficiency and product quality. Traditional filters typically employ a fixed filter plate structure, where materials are filtered by passing through the filter plates under gravity or pressure. However, this design has the following significant drawbacks:

[0003] Low filtration efficiency: During the filtration process, solid particles easily accumulate on the surface of the filter plate, forming a filter cake layer, which gradually increases the filtration resistance and significantly reduces the filtration efficiency. Especially under conditions of high solid content or high viscosity materials, the filtration efficiency is extremely low, requiring frequent shutdowns for cleaning, which seriously affects production efficiency.

[0004] Difficulty in observation: Traditional filters usually only have a single sight glass, which is affected by internal lighting, material turbulence or foam, making it difficult to clearly observe the filtration status, increasing the blindness of operation and safety hazards.

[0005] Inconvenient maintenance: Traditional filters require removing the top cover to disassemble the filter plate, which is difficult to operate and poses safety hazards.

[0006] Therefore, given the shortcomings of existing technologies, it is necessary to design a new type of filter to solve the above problems.

[0007] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0008] To overcome the shortcomings of the prior art, the present invention aims to disclose a novel filter that solves the problems of low efficiency, difficulty in observation, and inconvenience in maintenance of traditional filters.

[0009] This utility model discloses a novel filter, including a mounting frame and a filter body thereon. The inner cavity of the filter body is provided with a conical funnel and a detachable filter plate. The conical funnel divides the inner cavity of the filter body into an upper cavity and a lower cavity. The filter plate is located above the conical funnel structure, and its outer periphery is connected to the inner wall of the filter body through a sliding seal, used to cover the upper opening of the conical funnel. The top of the upper cavity is provided with a feed inlet; the bottom of the lower cavity is provided with a discharge outlet, and the side wall is provided with a vacuum port and two opposing sight glasses. The vacuum port is positioned higher than the horizontal level of the lower opening of the conical funnel. The detachable filter plate facilitates cleaning; the vacuum port accelerates liquid penetration through the filter plate through negative pressure, increasing the filtration speed; the funnel prevents the vacuum port from directly facing the filtrate, preventing the filtrate from being directly carried out from the vacuum port; the opposing sight glasses increase the internal brightness of the filter, making it easier to observe the internal filtration status and reducing blind spots.

[0010] Preferred technical solution: A support frame is provided between the conical funnel and the filter plate. The outer periphery of the support frame is connected to the inner wall of the filter body. The support frame supports the filter plate to prevent the filter plate from deforming due to the pressure difference between the upper and lower parts.

[0011] Preferred technical solution: The top of the filter body is provided with an openable cover, and an L-shaped swing arm is hinged on the mounting frame. The free end of the swing arm is connected to a lifting screw, and the lower end of the lifting screw is hinged to the center of the top of the cover, so as to realize the smooth lifting and lowering of the cover, and the cover can be moved away from the top of the filter body by using the swing arm.

[0012] Preferred technical solution: The top of the lifting screw is equipped with a manual turntable with anti-slip texture, which facilitates the rotation of the lifting screw.

[0013] Preferred technical solution: The cover is equipped with a nitrogen inlet and a pressure relief port. The nitrogen inlet is used to supply nitrogen into the upper cavity to increase the air pressure and improve the filtration efficiency. The pressure relief port is used to depressurize the upper cavity to avoid injury to the operator due to excessive pressure during the opening of the cover.

[0014] Preferred technical solution: The cover is also equipped with a safety valve to prevent the air pressure inside the filter from exceeding the standard and causing danger.

[0015] Preferred technical solution: The mating surface between the cover and the filter body is equipped with a sealing gasket, and a sealed connection is achieved through a ring array of bolts. This ensures airtightness under high pressure or vacuum conditions and prevents leakage.

[0016] Preferred technical solution: Pressure measuring ports are provided on the side walls of the upper and lower cavities, and each port can be connected to a pressure sensor. The pressure difference between the upper and lower cavities is monitored in real time to optimize filtration parameters.

[0017] Preferred technical solution: At least three connecting plates are evenly distributed around the outer periphery of the filter body, and a support plate is provided on the mounting frame at the corresponding position of the connecting plates. Multi-point support enhances the stability of the filter body.

[0018] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0019] 1) The pressure difference between the upper and lower chambers accelerates the liquid penetration of the filter plate, thereby increasing the filtration speed.

[0020] 2) Use a conical funnel to gather the filtrate towards the discharge port, avoiding direct contact between the filtrate and the vacuum port during its descent, thus reducing the possibility of the filtrate being sucked out of the vacuum port.

[0021] 3) The dual viewing mirrors face each other, increasing internal brightness and reducing blind spots.

[0022] 4) The detachable filter plate design and lifting cover structure simplify the cleaning and replacement process and reduce maintenance costs. Attached Figure Description

[0033] Example:

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides a specific implementation of a novel filter, which fully encompasses all the technical features of the technical solution, and its specific structure is as follows:

[0035] Main structure:

[0036] The filter body 2 is fixed to the support plate 13 of the mounting frame 1 by three evenly distributed connecting plates 2a, forming a stable support.

[0037] The inner cavity of the filter body 2 is provided with a conical funnel 3 and a detachable filter plate 4; the conical funnel 3 divides the inner cavity of the filter body 2 into an upper cavity 21 and a lower cavity 22; the filter plate 4 is located above the conical funnel 3, and its outer periphery is connected to the inner wall of the filter body 2 by a sliding sealing fit, which is used to cover the upper opening of the conical funnel 3.

[0038] Feeding and discharging system:

[0039] The upper cavity 21 has a feed inlet 23 at the top, which is connected by a flange.

[0040] The bottom of the lower cavity 22 is provided with a discharge port 24 and a vacuum port 25 on the side wall. The position of the vacuum port 25 is higher than the horizontal height of the opening below the conical funnel 3, so as to avoid the vacuum port 25 directly drawing away the filtrate.

[0041] Observation and monitoring:

[0042] Two sight glass openings 26 are symmetrically arranged on the side wall of the lower cavity 22, and pressure-resistant glass sight glasses are used.

[0043] Pressure measuring ports are respectively provided on the side walls of the upper cavity 21 and the lower cavity 22, and pressure sensors are connected to them.

[0044] Sealing and Safety:

[0045] The top of the filter body 2 is provided with an openable cover 27. A fluororubber sealing gasket is provided on the mating surface between the cover 27 and the body, and a sealed connection is achieved by 20 bolts.

[0046] The cover 27 is equipped with a nitrogen inlet 28 and a pressure relief port 29, and is also fitted with an air pressure safety valve.

[0047] A support frame 5 is provided between the conical funnel 3 and the filter plate 4. The outer periphery of the support frame 5 is connected to the inner wall of the filter body 2. The ribs on the support frame support the filter plate 4 to prevent the filter plate 4 from deforming due to the pressure difference between the upper and lower parts.

[0048] Opening mechanism:

[0049] An L-shaped swing arm 11 is hinged to the mounting frame 1, and its free end is connected to a lifting screw 12.

[0050] The top of the lifting screw 12 is equipped with a manual turntable 121 with anti-slip texture, and the lower end is connected to the top of the cover 27.

[0051] Work process:

[0052] Turn on the vacuum pump to reduce the air pressure in the lower chamber 22 through the vacuum port 25, use the pressure sensor to monitor the pressure difference between the upper chamber 21 and the lower chamber 22, and inject nitrogen into the upper chamber 21 through the nitrogen inlet 28 to increase the pressure if necessary.

[0053] The material is fed into the upper chamber 21 from the feed inlet 23, and the pressure difference between the upper chamber 21 and the lower chamber 22 is used to increase the filtration speed of the material.

[0054] The filtrate produced after material filtration is collected by the conical funnel 3 and conveyed from its lower opening to the discharge port 24.

[0055] Observe the filtration status through the dual viewing port 26;

[0056] After filtration is complete, rotate the manual turntable 121 to raise the cover 27, and swing arm 11 to remove the cover 27, allowing the filter plate 4 to be quickly removed for cleaning.

[0057] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
