Description

Technical Field

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

[0002] Candle filters, as a common solid-liquid separation device, are widely used in many industries such as chemical, food, pharmaceutical, and beverage. Their working principle is mainly to filter a mixture through a filter candle, allowing the liquid to pass through the candle while solid impurities are trapped on its surface, thus achieving solid-liquid separation. In industrial production, candle filters have high requirements for filtration efficiency, stability, and ease of slag discharge to ensure continuous production and stable product quality.

[0003] Currently, existing candle filters typically include multiple collection tubes, multiple filter candles, a cylinder, and a support plate. Multiple collection tubes are located at the top of the cylinder, and the filter candles are fixedly connected to the collection tubes at a single point at the top, collecting the filtered liquid through these tubes.

[0004] The existing technical solutions mentioned above have the following drawbacks: In the installation of existing candle filters, the candles rely solely on a single point of fixation at the top, and lack an effective support and positioning structure at the bottom. This causes the candles to tilt or misalign during installation, and interference occurs between adjacent candles. This not only reduces installation efficiency but also creates filter residue during cake blowing and slag discharge, preventing the residue from falling into the bottom collection chamber and causing filter residue residue to remain. Residual filter residue reduces the filtration area, damages the candles, and increases maintenance costs and pollution risks. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new fixing mechanism for candle filter, which can improve the filter element installation efficiency, filtration efficiency and working stability, and reduce the risk of filter residue pollution.

[0006] The above-mentioned utility model objective is achieved through the following technical solution:

[0007] A novel fixing mechanism for a candle filter includes multiple collection pipes, multiple filter candles, a cylinder, and a support plate. The multiple collection pipes are disposed at the top of the cylinder, and the top of each filter candle is detachably and fixedly connected to the collection pipe. Multiple sets of partitions are arranged at intervals at the bottom of the cylinder for fixing the bottom of the filter candle.

[0008] Through the above technical solution, multiple sets of baffles are set at the bottom of the cylinder to fix the bottom of the filter candle. Together with the liquid collection pipe, they form a stable support for the upper and lower ends of the filter candle, avoiding the tilting of the filter candle due to welding or assembly errors. This ensures that all filter candles are arranged vertically in the cylinder, thereby improving the filter element installation speed, working efficiency and filtration efficiency, while reducing the environmental pollution risks such as filter residue pollution caused by improper filter candle installation.

[0009] As a further technical solution of this utility model: each set of partitions includes a first partition and a second partition, and the first partition and the second partition are symmetrically arranged on both sides of the center line of the filter candle.

[0010] Through the above technical solutions, the symmetrically distributed baffles ensure that the filter candle is subjected to uniform force, avoids tilting and shaking, maintains its vertical position, and improves the filtration effect; they also provide precise positioning for filter candle installation, reduce installation deviations, speed up installation, and improve work efficiency.

[0011] As a further technical solution of this utility model: both sides of the first partition and both sides of the second partition are fixedly connected to the inner wall of the cylinder.

[0012] The above technical solution rigidly connects the two sides of the baffle to the inner wall of the cylinder to form a closed support structure, which enhances the installation stability of the baffle and prevents the baffle from shifting or deforming under the action of the filter candle's gravity or liquid pressure.

[0013] As a further technical solution of this utility model: the bottom ends of the first partition and the second partition are both inclined away from the inner wall of the cylinder, and the gap width between the first partition and the second partition gradually decreases from top to bottom along the longitudinal direction of the filter candle.

[0014] Through the above technical solution, the gap formed between the first and second partitions, which is wider at the top and narrower at the bottom, guides the filter cake to slide down the surface of the partitions to the bottom discharge port, avoiding the accumulation of slag in the gap of the filter candle, ensuring continuous and efficient filtration of the filter candle, thereby improving working efficiency and filtration efficiency; the structure of being wider at the top and narrower at the bottom provides a self-guiding effect when the filter candle is inserted, reducing the difficulty of alignment, and the inclined surface of the partition can disperse the fluid impact, reduce the filtration pressure loss, and indirectly improve the filtration efficiency.

[0015] As a further technical solution of this utility model: each of the filter candles is provided with a partition support rod at its bottom end, and the two ends of the partition support rod are respectively detachably and fixedly connected to the first partition and the second partition.

[0016] Through the above technical solution, the baffle support rod connects the bottom of the filter candle to the first baffle and the second baffle respectively, further restricting the swaying of the filter candle. At the same time, the baffle support rod shares the fluid pressure borne by the filter candle, avoiding the risk of breakage caused by stress concentration at the root of the filter candle, and greatly enhancing the fixing strength and stability of the bottom of the filter candle.

[0017] As a further technical solution of this utility model: one end of each liquid collecting tube is detachably and fixedly connected to the inner wall of the cylinder, and the other end is detachably and fixedly connected to the support plate.

[0018] Through the above technical solution, the two ends of the liquid collecting pipe are detachably and fixedly connected to the inner wall of the cylinder and the support plate, respectively, forming a support structure for the two ends of the liquid collecting pipe. The fixed ends can evenly distribute the weight and liquid pressure of the multiple filter candles connected on the liquid collecting pipe, avoid bending and deformation of the liquid collecting pipe due to unilateral force, and ensure the sealing and stability of the filter candle top connection.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. This utility model discloses a novel fixing mechanism for a candle filter. By setting a liquid collection pipe fixed at the top and partitions spaced apart at the bottom inside the cylinder, the top and bottom of the filter candle are fixed respectively, so that the filter candle is neatly and vertically fixed inside the cylinder. This avoids the filter candle being installed crookedly due to manufacturing and welding deviations, which would affect the installation of the liquid collection pipe. This improves the filter element installation speed, working efficiency and filtration efficiency, and reduces the risk of environmental pollution.

[0021] 2. This utility model discloses a novel fixing mechanism for a candle filter. The first and second partitions, which are inclined and have a gradually decreasing gap width from top to bottom, work together with the partition support rod at the bottom of the filter candle. This not only provides stable support and precise positioning for the bottom of the filter candle, effectively preventing the filter candle from shaking, but also guides the filter residue to slide smoothly into the slag collection chamber, improving filtration efficiency and reducing the risk of pollution caused by filter residue residue.

[0029] Reference Figure 1 and Figure 2 This utility model discloses a novel fixing mechanism for a candle filter, comprising multiple liquid collecting pipes 1, multiple filter candles 2, a cylinder 3, and a support plate 6; the multiple liquid collecting pipes 1 are disposed at the top of the inner wall of the cylinder 3, one end of each liquid collecting pipe 1 is detachably and fixedly connected to the inner wall of the cylinder 3, and the other end is detachably and fixedly connected to the support plate 6.

[0030] Multiple liquid collecting pipes 1 are arranged at intervals at the top of the cylinder 3. The length of the liquid collecting pipe 1 is adjusted according to its position in the cylinder 3. One end of the liquid collecting pipe 1 is connected to the flange in the cylinder 3 to form a set, and the other end of the liquid collecting pipe 1 is fixed to the support plate 6 by bolts.

[0031] Reference Figure 1 and Figure 3The filter candle 2 adopts a double-end fixed design. The top end of the filter candle 2 is detachably fixed to the liquid collection pipe 1. That is, multiple internal threads are opened on the liquid collection pipe 1, and each filter candle 2 has a matching external thread connector at its top end. The top end of the filter candle 2 is fixedly connected to the liquid collection pipe 1 through the internal and external threads. The bottom end of the filter candle 2 is fixed by multiple sets of baffles 5 arranged at intervals inside the bottom of the cylinder 3. The baffles 5 are made of corrosion-resistant stainless steel or engineering plastic to adapt to different filtration media and working conditions. This double-end fixed structure can eliminate installation deviations, make the filter candles 2 vertically arranged, and improve filtration efficiency.

[0032] Reference Figure 2 and Figure 3 Each set of baffles 5 includes a first baffle 51 and a second baffle 52, which are symmetrically arranged on both sides of the center line of the filter candle 2. Both sides of the first baffle 51 and the second baffle 52 are fixedly connected to the inner wall of the cylinder 3. To ensure the strength and sealing of the connection, welding can be used. The contact areas between the two sides of the first baffle 51 and the second baffle 52 and the inner wall of the cylinder 3 are melted at high temperature, and a metallurgical bond is formed after cooling. Furthermore, the surfaces of the first baffle 51 and the second baffle 52 can be covered with a wear-resistant coating to reduce wear caused by filter residue erosion.

[0033] Reference Figure 3 The bottom ends of the first partition 51 and the second partition 52 are inclined away from the inner wall of the cylinder 3. The gap width between the first partition 51 and the second partition 52 gradually decreases from top to bottom along the longitudinal direction of the filter candle 2, forming a V-shaped gap that is wider at the top and narrower at the bottom. The inclination angle can be flexibly adjusted within the range of 5°-30°. The gap width is designed according to the particle size of the filter residue, which ensures that the filter residue slides smoothly without affecting the fixation of the filter candle 2, effectively guiding the filter residue to the slag collection chamber and reducing the risk of residual pollution.

[0034] Furthermore, each filter candle 2 is provided with a partition support rod 4 at its bottom. The two ends of the partition support rod 4 are detachably and fixedly connected to the first partition 51 and the second partition 52, respectively, for example, by means of quick-release buckles, which facilitates quick disassembly during maintenance. The first partition 51 and the second partition 52 work together with the partition support rod 4 to provide stable support for the filter candle 2, prevent shaking and displacement during filtration, and improve working efficiency.

[0035] The actual installation process of the candle filter of this utility model is as follows:

[0036] First, connect the collection tube 1 and the filter candle 2. The collection tube 1 has an internal thread welded on it, and the top of the filter candle 2 is equipped with a matching external thread connector. Tighten the internal thread welded on the collection tube 1 to the external thread connector of the filter candle 2. The number of internal threads on the collection tube 1 determines the number of filter candles 2. This completes the installation of the filter candle 2 on the collection tube 1.

[0037] Next, the collection pipe 1, with the filter candle 2 installed, is hoisted into the cylinder 3. One end of the collection pipe 1 is equipped with a flange, which is paired and connected to the flange on the inner wall of the cylinder 3 by bolts or other means. Collection pipes 1 of different lengths are distributed in different positions in the cylinder 3, and their installation positions in the cylinder 3 are determined according to their lengths.

[0038] Next, locate the support plate 6 at the other end of the liquid collecting pipe 1. The support plate 6 is used to support the other end of the liquid collecting pipe 1. After aligning the mounting hole at the other end of the liquid collecting pipe 1 with the mounting hole on the support plate 6 at the tail end of the liquid collecting pipe 1, use bolts to fix it. Connect the flange at the other end of the liquid collecting pipe 1 to the flange inside the cylinder 3 to form a set, thus completing the initial fixing of the liquid collecting pipe 1.

[0039] A baffle support rod 4 is installed at the lower part of the filter candle 2. Multiple sets of baffles 5 are arranged at intervals at the bottom of the cylinder 3. Each set of baffles 5 includes a first baffle 51 and a second baffle 52 symmetrically arranged on both sides of the center line of the filter candle 2. The two ends of the baffle support rod 4 are placed on the corresponding first baffle 51 and second baffle 52, respectively, so that each set of baffle support rods 4 and baffles 5 corresponds one-to-one, further fixing the bottom end of the filter candle 2, thereby achieving overall fixed installation of the liquid collection tube 1. After one set of liquid collection tubes 1 is installed, the next set of liquid collection tubes 1 is installed in the same manner.

[0040] During the filtration process, after the liquid to be filtered enters the cylinder 3, solid-liquid separation occurs through the filter candle 2. The liquid passes through the filter candle 2 and is collected in the collection pipe 1, while solid impurities remain on the outside of the filter candle 2. Because the bottom ends of the first baffle 51 and the second baffle 52 are inclined away from the inner wall of the cylinder 3, and the gap width gradually decreases from top to bottom, during cake blowing and slag discharge, the filter cake can slide smoothly down the inclined baffles to the slag collection chamber at the bottom of the cylinder 3 under the action of gravity and airflow. This effectively avoids the problem of the filter cake being blocked between the filter candles 2 and unable to fall, thus achieving the emptying of the filter cake and ensuring the efficient and continuous operation of the filtration process.

[0041] The implementation principle of this utility model is as follows: The filter candle 2 adopts a double-end fixing method. The top end of the filter candle 2 is fixed by the internal thread of the liquid collecting tube 1 and the external thread of the top end of the filter candle 2. The bottom end of the filter candle 2 relies on multiple sets of partitions 5 inside the cylinder 3. Each set of partitions 5 includes a first partition 51 and a second partition 52 symmetrically arranged on both sides of the center line of the filter candle 2, which, together with the partition support rod 4, form a stable support. The wear-resistant coating on the surface of the first partition 51 and the second partition 52 resists the erosion of filter residue. Their bottom ends are inclined away from the inner wall of the cylinder 3, and the gap is V-shaped with a wider top and a narrower bottom, guiding the filter residue to slide down and preventing blockage.

[0042] Multiple collection pipes 1 are spaced apart at the top of the inner wall of the cylinder 3, with their lengths adjusted according to their positions. One end is connected to the inner wall of the cylinder 3 via a flange, and the other end is fixed to the support plate 6 with bolts. The filter candle 2 is first installed on the collection pipe 1 via threads, and then the whole assembly is hoisted and fixed at both ends to achieve a stable installation.

[0043] During filtration, the liquid undergoes solid-liquid separation through the filter candle 2, with the filtrate entering the collection pipe 1 and impurities remaining on the outside of the filter candle 2. During slag discharge, the inclined V-shaped structure of the first baffle 51 and the second baffle 52, combined with gravity and airflow, causes the filter slag to slide into the slag collection chamber at the bottom of the cylinder 3, preventing filter slag residue and ensuring continuous and efficient filtration.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
