Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter bag pressing mechanism. Background Technology

[0002] During the use of filters, the secure installation and proper sealing of filter bags are crucial. Existing filter bag clamping mechanisms have several problems. For example, some clamping mechanisms have complex structures, leading to difficult installation and operation, and wasting time and labor costs. The clamping effect of some clamping mechanisms is unstable, and filter bags are prone to loosening or displacement during operation, which affects the filtration effect, leading to a decrease in filtration accuracy, or even leakage, thus reducing the reliability and service life of the filter.

[0003] Chinese Patent Publication No. CN221333230U discloses a multi-core filter bag compression and installation structure, including an installation plate. The installation plate has multiple insertion slots circumferentially arranged on the installation plate. A compression ring is pressed onto each insertion slot. Multiple guide shafts are circumferentially arranged on the top of the compression rings. Compression springs are sleeved on the guide shafts. The lower end of the compression spring is connected to the compression ring, and the upper end is connected to a rotating snap-fit ​​component. The rotating snap-fit ​​component is slidably sleeved on the guide shaft and simultaneously snapped onto a fixed base. The fixed base is circumferentially arranged on the installation plate outside the insertion slots. This patented filter bag compression and installation mechanism has a complex structure and uses many parts, resulting in high industrial production costs. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a filter bag clamping mechanism. This filter bag clamping mechanism features a simple structure, convenient operation, and reliable clamping effect, significantly reducing production costs for enterprises.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A filter bag pressing mechanism includes a fixed base and a pressing plate. The fixed base has a plurality of slots fixed above its edge. The opening of the slots gradually decreases from the opening end to the inward side. The pressing plate has a protrusion above its edge that matches the slot. The pressing plate is rotatably mounted above the fixed base so that the protrusion is engaged in the slot.

[0007] The filter bag features a slot with an opening that gradually decreases in size from the opening towards the inside, located above the edge of the mounting base. A corresponding protrusion is also provided above the edge of the clamping plate, which is rotatably mounted above the mounting base so that the protrusion engages within the slot. This structural design ensures a stable connection and relative rotation between the clamping plate and the mounting base. During filter bag installation, the filter bag opening is first placed on the mounting base. Then, the clamping plate presses down on the filter bag opening. By rotating the clamping plate, the protrusion accurately engages with the slot, fixing the filter bag opening between the mounting base and the clamping plate. This tightening action ensures a secure installation of the filter bag, preventing it from shifting during filtration and affecting the filtration effect. This improves the stability and reliability of the filter operation.

[0008] Preferably, the inner surface of the slot is provided with anti-slip texture.

[0009] The inner surface of the slot is textured with anti-slip grooves. When the protrusion of the clamping plate engages with the slot, the anti-slip grooves increase the friction between the inner surface of the slot and the protrusion. This ensures that even under external forces such as vibration and fluid impact during filter operation, the protrusion is less likely to loosen or dislodge from the slot, further enhancing the stability of the connection between the clamping plate and the fixed base, ensuring the durability of the filter bag's compressed state, and thus improving the overall performance and service life of the filter.

[0010] Preferably, the outer surface of the protrusion is also provided with anti-slip texture to enhance the stability when the protrusion engages with the slot.

[0011] The outer surface of the protrusion is also textured with anti-slip patterns, which work in conjunction with the anti-slip patterns on the inner surface of the slot to further increase the friction between them. This two-way anti-slip design enhances the stability of the engagement from both contact surfaces. Even under more complex operating conditions, such as high-frequency vibration or high-flow-rate high-speed fluid impact, it ensures that the protrusion and the slot are tightly engaged, effectively preventing the filter bag from loosening or shifting during the filtration process, thus guaranteeing the filtration accuracy and efficiency of the filter.

[0012] Preferably, three slots are evenly spaced above the edge of the fixing seat, and three protrusions that match the annular slots are provided above the edge of the pressing plate.

[0013] Three evenly spaced slots are arranged on the upper edge of the fixing base, and three corresponding protrusions are provided on the clamping plate. This evenly spaced layout ensures that the clamping plate applies uniform pressure to the filter bag when it rotates and engages above the fixing base. This avoids damage to the filter bag due to excessive localized stress caused by uneven pressure distribution, or damage due to insufficient localized stress affecting the filtration effect. At the same time, the three slots and protrusions simplify the structure while ensuring the clamping effect, facilitating manufacturing and installation, and reducing production costs.

[0014] Preferably, the clamping plate is provided with an operating handle for easy rotation of the clamping plate by the operator.

[0015] An operating handle is provided on the clamping plate, offering operators a convenient point of leverage. When installing or removing filter bags, operators can easily rotate the clamping plate by holding the handle, engaging or disengaging the protrusions from the slots. This significantly reduces the difficulty and labor intensity of operation, improving the efficiency of filter bag installation and replacement. Furthermore, the operating handle also makes the operation safer and more stable, reducing the risk of hand injuries that could result from directly rotating the clamping plate by hand.

[0016] Preferably, the fixing base and the clamping plate are made of corrosion-resistant metal material.

[0017] The mounting base and clamping plate are made of corrosion-resistant metal materials, effectively resisting the erosion of various corrosive substances in the filter's working environment, such as acid and alkali solutions and chemical gases. This extends the service life of the mounting base and clamping plate, reduces structural damage and performance degradation caused by material corrosion, ensures the long-term stable operation of the filter bag clamping mechanism, reduces equipment maintenance and replacement costs, and also improves the filter's applicability in harsh working environments.

[0018] Preferably, the metal material is stainless steel.

[0019] The metal material is clearly defined as stainless steel, which possesses excellent comprehensive properties such as corrosion resistance, strength, and toughness. Using stainless steel in the filter bag clamping mechanism better meets the requirements of the working environment for corrosion resistance and strength. Compared with other corrosion-resistant metal materials, stainless steel has a relatively moderate cost, is widely available, and is easy to process and shape. This allows the filter bag clamping mechanism to maintain performance while offering good economy and practicality, which is beneficial for the product's promotion and application. Beneficial effects

[0020] (1) The filter bag pressing mechanism has a simple structure and is easy to operate, reducing the use of fixed structural parts and thus reducing the production cost of enterprises;

[0021] (2) The unique combination of slots and protrusions ensures that the filter bag is firmly pressed and the operation is stable and reliable; the anti-slip texture of the slots and protrusions enhances the locking stability and prevents loosening; the evenly distributed slots and protrusions make the pressure uniform and facilitate processing and installation.

[0022] (3) Stainless steel is used, which is corrosion resistant and extends service life. It is also economical and practical due to its moderate cost and easy processing. Attached Figure Description
