Description

Technical Field

[0001] This invention relates to the field of filter washing and drying machine technology, and more specifically, to a leak detection mechanism for filter washing and drying machines. Background Technology

[0002] A filter washing and drying machine is a piece of equipment that integrates filtration, washing and drying functions. It is widely used in the pharmaceutical, chemical, pesticide and food industries. Its main function is to vaporize and escape the moisture in the material by heating it to obtain solid material with a specified moisture content. This equipment is usually used to process sensitive, expensive, environmentally sensitive, corrosive or sterilizable materials to ensure the safety and hygiene of the production process.

[0003] For example, Chinese utility model patent CN220912564U discloses a leak detection device, which includes a leak detection mechanism, a gas supply component, and a container. The gas supply component supplies gas to the container. The leak detection mechanism is installed on the container and has an air inlet that communicates with the container. A connecting component is provided on the air inlet. The gas supply component is connected to the connecting component through a conduit. The connecting component includes a connecting seat, with an air guide port at the center of the connecting seat. An adjusting frame is provided on the outside of the air guide port. The adjusting frame consists of four side plates connected end to end. A traction part is provided on the outside of the adjusting frame. The traction part pulls the four side plates to move away from the connecting seat in an axial direction. When connecting rectangular pipes of different sizes, this leak detection device pulls the four side plates away from each other, expanding the enclosure size of the adjusting frame. This allows the adjusting frame to adapt to the connection requirements of rectangular pipes of different sizes, avoiding the need to frequently change the connecting equipment due to different pipe sizes, and improving detection efficiency.

[0004] Currently, most filter washing and drying machines on the market have a sealing structure between the vessel and the chassis to improve the sealing effect. However, due to the characteristics of the materials and long-term operation of the equipment, the sealing effect will decrease. In order to avoid environmental pollution and safety hazards caused by leakage, it is necessary to use a leakage detection agency to detect leaks. However, existing leakage detection agencies are difficult to quickly detect leaks between the vessel and the chassis and provide alarm reminders. This not only reduces the safety and reliability of the filter washing and drying machine, but also affects the effectiveness of the leakage detection agency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a leak detection mechanism for a filter washing and drying machine. The technical problem to be solved by the present invention is that the existing leak detection mechanisms are difficult to quickly detect leaks between the vessel body and the chassis and provide alarm reminders during use.

[0008] As a further aspect of the present invention: the liquid passage is an isosceles trapezoidal structure, and the dimension of the liquid passage near the movable channel is larger than the dimension of the liquid passage away from the movable channel.

[0009] As a further aspect of the present invention, it also includes a PLC control unit electrically connected to the leakage detection component, the PLC control unit being used for signal feedback when the two contact sensors are in contact and for transmitting electrical signals to an alarm for alarm activation.

[0010] As a further embodiment of the present invention: the guiding component includes a guiding groove and a guiding block; two guiding grooves are formed on both sides of the inner wall of the movable groove; the two guiding blocks are respectively fixed on the inner side and the outer side of the movable ring, and the guiding blocks are slidably engaged with the guiding grooves.

[0011] As a further aspect of the present invention: both the guide block and the guide groove are annular sawtooth structures, and the sawtooth shapes of the guide block and the guide groove are alternately arranged.

[0012] As a further aspect of the present invention: the installation and removal mechanism includes a connecting component; the connecting component includes a connecting groove and a connecting block; at least one connecting groove is provided on the bottom surface of the base body; the connecting block is inserted into the connecting groove and fixedly connected to the alarm, and the connecting block is electrically connected to the connecting groove.

[0013] As a further embodiment of the present invention: the installation and removal mechanism further includes a locking component; the locking component includes a moving groove, a sliding groove, a sliding block, a sliding rod, a spring B, a moving block, a receiving groove, a locking groove, and a locking block; the moving groove is provided in the connecting groove; the sliding groove is provided on the side of the moving groove away from the connecting groove; the sliding block is slidably disposed in the sliding groove; the sliding rod is fixedly disposed on the sliding block, and the end of the sliding rod extends to the outside through the sliding groove; the spring B is sleeved on the sliding rod, and the two ends of the spring B are respectively fixedly connected to the inner wall of the sliding groove and the sliding block; the moving block is slidably disposed in the moving groove and contacts the side of the sliding block; the receiving groove is provided on the side of the sliding block near the moving groove, and the moving block is inserted into the receiving groove; the locking groove is provided on the side of the connecting block near the moving groove; the locking block is slidably disposed in the moving groove and fixedly connected to the moving block, and the locking block is inserted into the locking groove.

[0014] As a further aspect of the present invention: the longitudinal section of the moving block is a right-angled trapezoidal structure, and the inclined surface of the moving block is facing downward and is positioned close to the direction of the sliding block.

[0015] As a further aspect of the present invention: the locking block has a spherical structure, and the spherical surface of the locking block contacts the inner wall of the moving groove.

[0016] The beneficial effects of this invention are as follows: 1. This invention, by incorporating a leak detection component, allows the leaking liquid to flow from the liquid flow channel into the movable channel and onto the movable ring when a leak occurs in the filter washing and drying machine body. Due to the V-shaped structure of the liquid collection channel, the leaking liquid is concentrated at its tip. Simultaneously, the weight of the leaking liquid causes the movable ring to slide downwards within the movable channel, causing spring A to contract until contact sensor A and contact sensor B come into contact. At this point, the PLC control unit activates the alarm. Furthermore, a gap exists between the movable ring and the liquid flow channel, allowing the leaking liquid to pass through the channel into the detection tube and ultimately into the collection cylinder. Compared to existing technologies, this invention has a reasonable structural design. By utilizing the gravity of the leaking liquid, it can quickly detect leaks in the filter washing and drying machine body and provide an alarm, significantly improving the safety and reliability of the machine body.

[0017] 2. By setting a guide groove and a guide block, when the movable ring slides downward in the movable groove, the guide block will slide in the guide groove. Since both the guide block and the guide groove are annular sawtooth structures, they can not only restrict and guide the position of the movable ring in the movable groove, preventing the movable ring from rotating in the movable groove and affecting the position between the tip of the liquid pool and the liquid channel, but also extend the contact area between the guide block and the guide groove to improve the sealing performance between the guide block and the guide groove.

[0018] 3. This invention employs an installation and removal mechanism. By pulling the ring on the sliding rod, the sliding rod causes the sliding block to slide downwards within the sliding groove, compressing spring B until it reaches its maximum contraction. At this point, the alarm moves downwards, causing the connecting block to slide downwards within the connecting groove. This causes the inner wall of the locking groove to press against the spherical surface of the locking block, allowing the locking block to slide within the moving groove. The moving block is then inserted into the receiving groove until its side contacts the inner wall of the receiving groove. At this point, the locking block moves out of the locking groove, and so on until the connecting block moves out of the connecting groove. After inserting the connector into the slot, select a suitable alarm, insert the connector into the slot, and ensure that the top surface of the connector contacts the top wall of the slot. Then, release the pull ring on the sliding rod. Under the elastic force of spring B, the sliding block will drive the sliding rod to slide upward in the sliding slot, causing the inner wall of the receiving slot to press against the inclined surface of the moving block. This causes the moving block to drive the locking block to slide in the opposite direction in the moving slot until the side of the moving block contacts the side of the sliding block. At this point, the locking block is inserted into the locking slot, making it convenient to disassemble and install the alarm and select or replace a suitable alarm. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, the present invention provides a leak detection mechanism for a filter washing and drying machine, including a filter washing and drying machine body 1, a leak detection component 2, a guide component 3, and an installation and removal mechanism 4; the filter washing and drying machine body 1 includes a machine body 101 and a chassis body 102; the chassis body 102 is detachably installed at the bottom of the machine body 101; the chassis body 102 includes a base body 1021, casters 1022, and a sintered mesh 1023; four casters 1022 are evenly fixed on the bottom surface of the base body 1021; the sintered mesh 1023 is detachably installed in the positioning groove of the base body 1021; the leak detection component 2 is arranged on the base body 1021; The leakage detection component 2 includes a flow channel 201, a movable channel 202, a movable ring 203, a liquid collection channel 204, a spring A 205, a liquid passage channel 206, a detection tube 207, a liquid collection cylinder 208, and an alarm 209; the base body 1021 has a flow channel 201; the flow channel 202 is formed inside the flow channel 201, and a contact sensor A is provided on the bottom wall of the movable channel 202; the movable ring 203 is slidably disposed in the movable channel 202 through the guide component 3, and a contact sensor B is provided on the bottom surface of the movable ring 203; a liquid collection channel 204 is formed on the side of the movable ring 203 near the flow channel 201; the two ends of the two springs A 205 are fixedly connected to the inner wall of the movable channel 202 and the movable ring 203, respectively; the movable channel 201... Two symmetrical liquid passage channels 206 are provided inside the base body 1021; two detection tubes 207 are symmetrically fixed on the base body 1021 and are connected to the liquid passage channels 206, and valves are provided on the detection tubes 207; a liquid collection cylinder 208 is detachably installed on the end of the detection tubes 207; two alarms 209 are connected to the base body 1021 through the installation and removal mechanism 4; the liquid collection channel 204 has a V-shaped structure and the tip of the liquid collection channel 204 is set downward; the liquid passage channel 206 has an isosceles trapezoidal structure, and the dimension of the liquid passage channel 206 on the side closer to the movable channel 202 is larger than the dimension of the side of the liquid passage channel 206 away from the movable channel 202, so as to facilitate increasing the inlet diameter of the leaking liquid; the tip of the liquid collection channel 204 is on the same plane as the inner top wall of the liquid passage channel 206; It also includes a PLC control unit electrically connected to the leak detection component 2. The PLC control unit is used for signal feedback when the two contact sensors come into contact and for transmitting electrical signals to the alarm 209 to trigger an alarm.

[0023] This invention, by setting up a leak detection component 2, allows the leaking liquid to enter the movable tank 202 from the liquid flow channel 201 when a leak occurs in the filter washing and drying machine body 1, and fall onto the movable ring 203. Since the liquid collection tank 204 has a V-shaped structure, it can collect the leaking liquid at its tip. Simultaneously, due to the weight of the leaking liquid, the movable ring 203 slides downwards within the movable tank 202, causing the spring A205 to contract until the contact sensor A and contact sensor B come into contact. At this point, the PLC control unit will control the alarm 209 to sound an alarm. Furthermore, a gap exists between the movable ring 203 and the liquid passage channel 206, allowing the leaking liquid to enter the detection tube 207 through the liquid passage channel 206 and ultimately into the collection cylinder 208. Compared to existing technologies, this invention has a reasonable structural design. Through the gravity of the leaking liquid, it can quickly detect leaks in the filter washing and drying machine body 1 and provide an alarm, greatly improving the safety and reliability of the filter washing and drying machine body 1.

[0024] As a preferred embodiment, the guide component 3 includes a guide groove 301 and a guide block 302; two guide grooves 301 are opened on both sides of the inner wall of the movable groove 202; the two guide blocks 302 are respectively fixed on the inner side and the outer side of the movable ring 203, and the guide blocks 302 and the guide grooves 301 are slidably engaged; both the guide blocks 302 and the guide grooves 301 are annular sawtooth structures, and the sawtooth shape of the guide blocks 302 and the sawtooth shape of the guide grooves 301 are staggered.

[0025] By setting a guide groove 301 and a guide block 302, the present invention allows the movable ring 203 to slide downward within the movable groove 202, causing the guide block 302 to slide within the guide groove 301. Since both the guide block 302 and the guide groove 301 are annular sawtooth structures, they can not only restrict and guide the position of the movable ring 203 within the movable groove 202, preventing the movable ring 203 from rotating within the movable groove 202 and affecting the position between the tip of the liquid collection tank 204 and the liquid passage tank 206, but also extend the contact area between the guide block 302 and the guide groove 301 to improve the sealing performance between them.

[0026] As a preferred embodiment, the installation and removal mechanism 4 includes a connecting component 5; the connecting component 5 includes a connecting groove 501 and a connecting block 502; the bottom surface of the base body 1021 has two symmetrically opened connecting grooves 501; the connecting block 502 is inserted into the connecting groove 501 and fixedly connected to the alarm 209, and the connecting block 502 is electrically connected to the connecting groove 501. The installation and removal mechanism 4 also includes a locking component 6; the locking component 6 includes a moving groove 601, a sliding groove 602, a sliding block 603, a sliding rod 604, a spring B 605, a moving block 606, a receiving groove 607, a locking groove 608, and a locking block 609; the moving groove 601 is provided in the connecting groove 501; the sliding groove 602 is provided on the side of the moving groove 601 away from the connecting groove 501; the sliding block 603 is slidably disposed in the sliding groove 602; the sliding rod 604 is fixedly disposed on the sliding block 603, and the end of the sliding rod 604 extends to the outside through the sliding groove 602; the spring B 605 is sleeved on the sliding rod 604, and the two ends of the spring B 605 are fixedly connected to the inner wall of the sliding groove 602 and the sliding block 603 respectively; the moving block 606 is slidably disposed in the moving groove 601 and contacts the side of the sliding block 603; the sliding block 603 is close to the sliding groove 601. A receiving groove 607 is provided on the side near the moving groove 601, and the moving block 606 is inserted into the receiving groove 607; a locking groove 608 is provided on the side of the connecting block 502 near the moving groove 601; a locking block 609 is slidably inserted into the moving groove 601 and fixedly connected to the moving block 606, and the locking block 609 is inserted into the locking groove 608; the longitudinal section of the moving block 606 is a right-angled trapezoidal structure, and the inclined surface of the moving block 606 is facing downward and close to the sliding block 603; the locking block 609 is a spherical structure, and the spherical surface of the locking block 609 contacts the inner wall of the moving groove 601 to facilitate the restriction of the range of motion of the moving block 606 and the locking block 609; the inner wall size of the receiving groove 607 is larger than the size of the moving block 606, and when the spring B605 is contracted to its maximum extent, the moving block 606 completely overlaps with the receiving groove 607.

[0027] This invention utilizes an installation / removal mechanism 4. By pulling the ring on the sliding rod 604, the sliding rod 604 causes the sliding block 603 to slide downwards within the sliding groove 602, causing the spring B605 to contract under pressure until it reaches its maximum contraction. At this point, the alarm 209 moves downwards, causing the connecting block 502 to slide downwards within the connecting groove 501. This causes the inner wall of the locking groove 608 to press against the spherical surface of the locking block 609, resulting in the locking block 609 driving the moving block 606 to slide within the moving groove 601. The moving block 606 is then able to insert into the receiving groove 607 until its side contacts the inner wall of the receiving groove 607. At this point, the locking block 609 moves out of the locking groove 608, and the connecting block 502 moves out of the connecting groove 501. After selecting the appropriate alarm 209, insert the connecting block 502 into the connecting groove 501, ensuring the top surface of the connecting block 502 contacts the top wall of the connecting groove 501. Then, release the pull ring on the sliding rod 604. Under the elastic force of the spring B605, the sliding block 603 will cause the sliding rod 604 to slide upward in the sliding groove 602, causing the inner wall of the receiving groove 607 to press against the inclined surface of the moving block 606. This causes the moving block 606 to drive the locking block 609 to slide in the opposite direction in the moving groove 601 until the side of the moving block 606 contacts the side of the sliding block 603. At this point, the locking block 609 is inserted into the locking groove 608, facilitating the disassembly and installation of the alarm 209 and allowing for the selection or replacement of a suitable alarm 209.

[0028] Working principle of this invention: When the filter washing and drying machine body 1 leaks, the leaked liquid enters the movable tank 202 from the liquid flow tank 201 and falls onto the movable ring 203. Because the liquid collection tank 204 has a V-shaped structure, it can collect the leaked liquid at its tip. Simultaneously, due to the weight of the leaked liquid, the movable ring 203 slides downwards within the movable tank 202, causing the guide block 302 to slide within the guide tank 301. This causes the spring A205 to contract under force until the contact sensor A and contact sensor B interact. Upon contact, the PLC control unit will control the alarm 209 to sound an alarm. A gap exists between the movable ring 203 and the liquid passage 206, allowing the leaked liquid to pass through the liquid passage 206 into the detection tube 207, and ultimately into the collection cylinder 208. When the alarm 209 needs to be replaced, pulling the pull ring on the sliding rod 604 causes the sliding rod 604 to drive the sliding block 603 downwards within the sliding groove 602, causing the spring B605 to contract under force until it reaches its maximum contraction. At this point, the alarm 209 moves downwards. 09. Slide the connecting block 502 downwards within the connecting groove 501, causing the inner wall of the locking groove 608 to press against the spherical surface of the locking block 609. This causes the locking block 609 to drive the moving block 606 to slide within the moving groove 601, allowing the moving block 606 to insert into the receiving groove 607 until the side of the moving block 606 contacts the inner wall of the receiving groove 607. At this point, the locking block 609 moves out of the locking groove 608. After the connecting block 502 moves out of the connecting groove 501, select a suitable alarm 209, insert the connecting block 502 into the connecting groove 501, and then... The top surface of block 502 contacts the inner top wall of the connecting groove 501. Then, the pull ring on the sliding rod 604 is released. Under the elastic force of spring B605, the sliding block 603 will drive the sliding rod 604 to slide upward in the sliding groove 602, causing the inner wall of the receiving groove 607 to press the inclined surface of the moving block 606. This causes the moving block 606 to drive the locking block 609 to slide in the opposite direction in the moving groove 601 until the side of the moving block 606 contacts the side of the sliding block 603. At this time, the locking block 609 is inserted into the locking groove 608, and the replacement of the alarm 209 is completed.
