Description

Technical Field

[0001] This utility model relates to the field of material filtration technology, and in particular to a core-pulling device and filtration equipment. Background Technology

[0002] In the production of dairy and liquid products, angle filters are a key filtration device widely used in CIP (Clean In Place) systems, mixing systems, and raw material storage. Their main function is to effectively intercept and collect impurities and foreign matter in materials, ensuring product quality and production safety.

[0003] Traditional angle filters typically consist of a filter element, a housing, and a sealing assembly. The O-ring at the front of the filter element makes tight contact with the housing to achieve a seal. While this design effectively prevents material leakage, maintenance and filter element replacement often require operators to pull the filter element outwards. Due to the significant frictional resistance between the O-ring and the housing, it's difficult for the user to maintain consistent force. Furthermore, excessively fast or long pulls can cause residual liquid at the bottom of the tank to spill onto the ground, contaminating the production environment and increasing cleaning workload. Utility Model Content

[0004] The purpose of this invention is to provide a core-pulling device that not only facilitates the application of force and control of the force distance, reducing cleaning workload, but also enables the rapid disassembly of adjacent structures to be removed.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] The first aspect of this utility model provides a core-pulling device, such as... Figure 1 As shown, the device includes a bracket 1 and an external pulling mechanism 2. The external pulling mechanism 2 includes an operating component 21, a slide rod 22, and a connecting arm 23. The slide rod 22 slides and engages with the bracket 1 along its own extension direction. One end of the connecting arm 23 is rotatably connected to the slide rod 22 around its extension direction, and the other end is used to detachably connect to the structure 31 to be pulled out of the filter 3. The operating component 21 is rotatably connected to the bracket 1 and is used to drive the slide rod 22 to slide relative to the bracket 1.

[0025] like Figure 2 As shown, in use, the connecting arm 23 is connected to the pull-out structure 31 of the filter 3. The user can then rotate the operating component 21 to slide the sliding rod 22 relative to the bracket 1. The sliding rod 22 drives the connecting arm 23 to pull out the pull-out structure 31. Since one end of the connecting arm 23 can be rotatably connected to the sliding rod 22 around its extension direction, after pulling out the pull-out structure 31 on one side of the filter 3, the connecting arm 23 can be rotated to connect to the pull-out structure 31 on the other side of the filter 3, achieving quick disassembly of adjacent pull-out structures 31.

[0026] The aforementioned core-pulling device replaces the direct external pulling of the structure to be pulled out 31 by rotating the operating component 21. This not only makes it easier for personnel to maintain the force application action and control the force application distance, but also effectively alleviates the problem of residual liquid at the bottom of the can flowing to the ground after external pulling, reducing the amount of cleaning work, and also enables the rapid disassembly of adjacent structures to be pulled out 31.

[0027] There are several ways to detach the connecting arm 23 from the structure to be pulled out, such as snapping the connecting arm 23 to the structure to be pulled out, connecting it with bolts, or connecting it with pins.

[0028] In alternative implementations, such as Figure 3 As shown, the end of the connecting arm 23 away from the slide bar 22 is recessed with a first slot 231 for engaging with the structure to be pulled out 31.

[0029] In use, the first slot 231 is engaged with the structure to be pulled out 31, and the side of the connecting arm 23 in the sliding direction of the slide rod 22 can abut against the structure to be pulled out 31, thereby pulling out the structure to be pulled out through the aforementioned side. Of course, the structure to be pulled out 31 can also be pulled out through the frictional force of the contact surface between the first slot 231 and the structure to be pulled out 31.

[0030] The above-described embodiment achieves a quick, reliable, and repeatable detachable connection with the structure to be pulled out 31 by providing a first slot 231 at the end of the connecting arm 23, further optimizing the ease of operation of the core-pulling device and the stability of the pull-out process.

[0031] The first slot 231 may be U-shaped, V-shaped, or semi-circular, with its opening facing the direction in which the structure to be removed 31 is inserted. An elastic buffer layer (such as a rubber pad or silicone layer) may be provided on the inner wall surface of the first slot 231 to avoid jamming and hard friction between the first slot 231 and the structure to be removed 31 during removal.

[0032] Before pulling out the structure 31 to be pulled out, the operator rotates the connecting arm 23 to a position above one side of the filter 3, aligns the first slot 231 with the structure 31 to be pulled out, and presses it down so that the structure 31 to be pulled out is inserted into the first slot 231 to complete the detachable connection. When it is necessary to pull out the structure 31 to be pulled out of the other side of the filter 3, the connecting arm 23 can be rotated upward, and then the sliding rod 22 can be slid through the operating component 21 to make the connecting arm 23 avoid the structure 31 to be pulled out. Then, the connecting arm 23 is rotated to a position below the other side of the filter 3, the first slot 231 is aligned with the structure 31 to be pulled out, and it is lifted up so that the structure 31 to be pulled out is inserted into the first slot 231 to complete the detachable connection.

[0033] During the above operation, when switching between the two filters 3, it is necessary to slide the slide bar 22 so that the connecting arm 23 avoids the pull-out structure 31. To facilitate user operation, in optional embodiments, such as Figure 4 As shown, the end of the connecting arm 23 away from the slide bar 22 is recessed with a second slot 232 for engaging with the structure to be pulled out 31. The second slot 232 and the first slot 231 are arranged opposite to each other along a first direction, which is perpendicular to the extension direction of the connecting arm 23 and the extension direction of the slide bar 22.

[0034] Thus, when it is necessary to switch to pulling out the other side of the structure 31 to be pulled out, the user can simply rotate the connecting arm 23 180° to make the second slot 232 engage with the other side of the structure 31 to be pulled out, without having to make the aforementioned avoidance operation. Moreover, under the action of gravity, both the second slot 232 and the first slot 231 can be engaged with the structure 31 to be pulled out, without the two slots needing to be tightly locked with the structure 31 to be pulled out. The machining accuracy requirements for the two slots are low, making it convenient for the user to pull out the two adjacent structures 31 to be pulled out.

[0035] In alternative implementations, such as Figure 1 and Figure 5 As shown, the operating component 21 includes a pull rod 211 and a connecting rod 212. The pull rod 211 is rotatably connected to the bracket 1 via a rotating shaft, so that the pull rod 211 can swing relative to the bracket 1 within a preset angle range around the rotating shaft. One end of the connecting rod 212 is rotatably connected to the pull rod 211, and the other end is rotatably connected to the slide rod 22, thereby forming a linkage mechanism composed of the pull rod 211, the connecting rod 212, and the slide rod 22.

[0036] When the user applies force to the pull rod 211 and causes it to swing upward or downward, the motion is transmitted to the slide rod 22 through the connecting rod 212, driving the slide rod 22 to reciprocate linearly relative to the bracket 1 along its own extension direction. Specifically, the swinging of the pull rod 211 causes the connecting rod 212 to change angle, thereby pushing or pulling the slide rod 22 to slide relative to the bracket 1. When the pull rod 211 swings downward, it can achieve stable traction on the external structure 31 to be pulled out.

[0037] The aforementioned structure converts the user's rotational motion into linear output motion of the slide bar 22, featuring smooth transmission and significant torque amplification, which helps reduce the force required for manual application and improves disassembly efficiency. Furthermore, since all connections are revolute joints, the overall mechanism moves smoothly, experiences minimal wear, and boasts high reliability, making it suitable for applications requiring frequent operation.

[0038] In an optional embodiment, one end of the pull rod 211 is rotatably connected to the bracket 1, and the other end is a handheld end. The connecting rod 212 is rotatably connected between the two ends of the pull rod 211, and the rotatable connection between the connecting rod 212 and the pull rod 211 is close to the end of the pull rod 211 that is rotatably connected to the bracket 1.

[0039] The above-described embodiment enables the lever 211 to effectively amplify and transmit the force applied by the operator to the connecting rod 212 when the lever 211 is rotated under force, thereby pushing the slide rod 22 to perform linear reciprocating motion along the bracket 1.

[0040] The tie rod 211 and the connecting rod 212 can both be long and narrow, and can be made of metal or high-strength engineering plastics, such as 304 stainless steel, to ensure good structural stability and fatigue strength under repeated operation.

[0041] In an optional embodiment, the bracket 1 includes a plurality of mounting positions arranged side by side for mounting the filter 3, and at least one side of any mounting position is provided with an external pull-out mechanism 2.

[0042] After the external pulling mechanism 2 on one side of the filter 3 completes the disassembly of the structure 31 to be pulled on the filter 3, the connecting arm 23 can rotate around the axis of the slide rod 22 to switch to the filter 3 corresponding to the adjacent installation position for operation, thereby realizing continuous and efficient core removal operation in multiple positions.

[0043] In alternative implementations, such as Figure 1 As shown, the bracket 1 includes a crossbeam 11 and a support 12, which are fixedly connected by fasteners (such as bolts or screws) or welding to improve the overall structural strength and assembly stability. The crossbeam 11 extends horizontally and has multiple side-by-side mounting positions, each adapted for installing the filter 3. For example, the filter 3 can be positioned and installed using clamps or flange connections, ensuring the stability of the filter 3 during use.

[0044] Support 12 is fixedly connected to the top of crossbeam 11 to support the relevant moving parts of the pull-out mechanism 2. Specifically, slide rod 22 is slidably engaged with support 12 along its axial direction; operating assembly 21 is rotatably connected to support 12. Specifically, pull rod 211 in operating assembly 21 is mounted on support 12 via a pivot or hinge structure, enabling it to rotate relative to support 12 about a predetermined axis.

[0045] In alternative implementations, such as Figure 1 As shown, the support 12 includes a first support beam 121 and a second support beam 122 connected to the first support beam 121. At least one of the first support beam 121 and the second support beam 122 is connected to the crossbeam 11 to achieve stable assembly between the support 12 and the crossbeam 11.

[0046] The first support beam 121, the second support beam 122, and the crossbeam 11 are arranged perpendicularly to each other in pairs, forming a stable support frame structure. This layout not only facilitates the rational spatial distribution of the components but also effectively transmits and disperses the forces generated during the pull-out process, reduces stress concentration, and improves the stability and reliability of the device during operation.

[0047] The slide rod 22 passes through the first support beam 121 along its axial direction and slides in cooperation with the first support beam 121. For example, by setting a sliding bearing or linear guide structure on the first support beam 121, the slide rod 22 can slide smoothly along a straight line under the action of force, reducing the off-center load and frictional resistance during the movement process, and ensuring the accurate transmission of the pull-out force.

[0048] When the slide rod 22 and the first support beam 121 are in sliding engagement through the sliding bearing, snap rings are provided at both ends of the sliding bearing and the first support beam 121 to limit the axial position of the sliding bearing relative to the support 12.

[0049] Furthermore, the operating component 21 is rotatably connected to the second support beam 122. Specifically, one end of the pull rod 211 is hinged to the second support beam 122 via a pivot, thereby enabling the operating component 21 to rotate relative to the bracket 1 within a preset angle range.

[0050] The above-described embodiment sets the first support beam 121, the second support beam 122 and the crossbeam 11 into a three-dimensional frame structure that is perpendicular to each other. This not only improves the overall structural strength and assembly stability of the core-pulling device, but also achieves reasonable spatial separation and coordinated cooperation between the slide rod 22 and the operating component 21, which is convenient for maintenance and operation.

[0051] The second aspect of this utility model provides a filtration device, which includes a filter 3 and the aforementioned core-pulling device, wherein the filter 3 is mounted on a bracket 1.

[0052] The filtration device provided in the second aspect of this utility model has the core-pulling device provided in the first aspect of this utility model, and thus has all the beneficial effects of the core-pulling device provided in the first aspect of this utility model.

[0053] In an optional embodiment, the filter 3 includes a pull-out structure 31, which may include a filter element and has a handle 311 connected to the end of the filter element.

[0054] The handle 311 has a first hand-holding portion 3111 and a second hand-holding portion 3112 extending in a direction parallel to the outward pulling direction of the structure to be pulled out 31. The length of the first hand-holding portion 3111 and the second hand-holding portion 3112 is 13-18cm, for example, 13cm, 15cm, 16.5cm or 18cm.

[0055] The above-described embodiment increases the length of the handle, making it easier for the user to apply force when installing the pull-out structure 31, ensuring that the filter element can be accurately aligned with the hole at the bottom of the filter housing 3, and preventing damage to the sealing interface.

[0056] Specifically, the handle 311 can have a "U" shaped structure, such as... Figure 2 As shown, the handle 311 also includes an abutting part 3113 connected between the first hand-holding part 3111 and the second hand-holding part 3112. When the pull-out structure 31 is pulled outward, the side of the connecting arm 23 in the sliding direction of the slide bar 22 can abut against the abutting part 3113.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
