Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof, in particular to a fully enclosed explosion-proof device for a horizontal centrifuge. Background Art

[0002] The horizontal centrifuge is an industrial equipment that mainly uses the principle of high-speed rotation to achieve the effect of solid-liquid separation.

[0003] Horizontal centrifuges have a wide range of applications, mainly due to their low maintenance costs, small footprint, and advanced technology.

[0004] Existing horizontal centrifuges have been found in long-term use and observation that there is a safety hazard of explosion after long-term use. When the horizontal centrifuge explodes, flames will appear. At this time, as the flame continues to burn, it will cause a secondary explosion of the horizontal centrifuge, thereby causing secondary damage to personnel or economy.

[0005] To this end, the utility model provides a fully enclosed explosion-proof device for a horizontal centrifuge. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model is a fully enclosed explosion-proof device for a horizontal centrifuge, comprising a guardrail; four fixing components are fixedly connected to the bottom of the guardrail; the four fixing components are symmetrically distributed at the four corners of the bottom of the guardrail; a placement plate is provided on the top of the guardrail; a plurality of needle punctures are fixedly connected to the top of the placement plate; the plurality of needle punctures are equidistantly distributed on the top of the placement plate; a plurality of leakage holes are opened on the top of the placement plate; the plurality of leakage holes are equidistantly distributed on the top of the placement plate and are staggered with the needle punctures; A flexible plate is fixedly connected to the top of the placement plate; the flexible plate is arranged in an arc shape; a plurality of first connecting rods are fixedly connected to a side wall of the flexible plate facing the top of the placement plate; the plurality of first connecting rods are equidistantly distributed at the bottom of the flexible plate; the ends of the plurality of first connecting rods are fixedly connected to liquid storage bags; the plurality of liquid storage bags correspond to the positions of acupuncture. Through the above structure, after the horizontal centrifuge explodes, the liquid can quickly come into contact with the horizontal centrifuge, thereby reducing the fire caused by the explosion of the horizontal centrifuge, thereby reducing the occurrence of secondary explosions.

[0008] Preferably, two support components are fixedly connected to the side wall of the guardrail; the two support components are arranged in a U shape; two second connecting rods are fixedly connected to the middle of the support components; a plurality of through holes are formed in the top of the flexible plate; hooks are fixedly connected to the ends of the second connecting rods; a plurality of the hooks all penetrate through the through holes. Through the above structure, the flexible plate can be hung and stretched by the support components, which can reduce the loosening of the flexible plate, resulting in the direct contact between the liquid storage bag and the acupuncture needle when the horizontal centrifuge is working normally, thereby causing the liquid inside the liquid storage bag to spill out, and finally causing the short circuit of the horizontal centrifuge.

[0009] Preferably, a pull rope is fixedly connected to the bottom of the placement plate; the pull rope penetrates through the guardrail and extends to the inside of the guardrail; a counterweight block is fixedly connected to the end of the pull rope; the counterweight block is inside the guardrail. Through the above structure, the placement plate can be continuously stretched, thereby reducing the shaking of the placement plate. At the same time, when the horizontal centrifuge explodes, the counterweight block will be shaken off, so that the counterweight block hits the bottom of the placement plate. At this time, the acupuncture needle on the top of the placement plate can contact the liquid storage bag more quickly, so that the liquid inside the liquid storage bag can be quickly ejected and contact the exploding horizontal centrifuge.

[0010] Preferably, a clamping groove is formed in the side wall of the guardrail; the clamping groove is located at a position close to the end of the guardrail; a clamping block is detachably installed inside the clamping groove; a collecting box is fixedly connected to the end of the clamping block; the collecting box is arranged in an arc shape; two symmetrically arranged baffle plates are fixedly connected to the top of the clamping block. Through the above structure, the excess liquid accumulated on the top of the placement plate and the liquid inside the liquid storage bag can be collected and uniformly processed, thereby reducing the waste of liquid caused by the liquid falling to the outside.

[0011] Preferably, two dust-proof plates are fixedly connected to the side wall of the flexible plate; the two dust-proof plates are symmetrically arranged; the ends of the dust-proof plates are fixedly connected to the top of the acupuncture needle. Through the above structure, the acupuncture needle and the liquid storage bag can be protected, and the dust and impurities in the air are reduced from being adsorbed on the surface of the acupuncture needle or the liquid storage bag for a long time over time, resulting in too much dust accumulation when an explosion occurs, and the situation where the acupuncture needle is difficult to break the liquid storage bag.

[0012] Preferably, a wire guide plate is fixedly connected to the end of the clamping groove; the wire guide plates are symmetrically arranged and are inclined. Through the above structure, the deviation of the position when the clamping block is installed inside the clamping groove can be reduced, resulting in the situation where it is difficult to collect the liquid inside the liquid storage bag.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The fully enclosed explosion-proof device for a horizontal centrifuge described in the utility model performs spraying treatment inside the guardrail, so that after the explosion of the horizontal centrifuge, the liquid can quickly contact the horizontal centrifuge, thereby reducing the fire caused by the explosion of the horizontal centrifuge, thereby reducing the occurrence of secondary explosions.

[0015] 2. The fully enclosed explosion-proof device for a horizontal centrifuge described in the utility model can hang and stretch the flexible plate through a support assembly to reduce the possibility of the flexible plate becoming loose, which would cause the liquid storage capsule to come into direct contact with the needle when the horizontal centrifuge is working normally, thereby causing the liquid inside the liquid storage capsule to spill out, and eventually causing a short circuit in the horizontal centrifuge.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, a fully enclosed explosion-proof device for a horizontal centrifuge described in an embodiment of the utility model comprises a guardrail 1; four fixing components 12 are fixedly connected to the bottom of the guardrail 1; the four fixing components 12 are symmetrically distributed at the four corners of the bottom of the guardrail 1; a placement plate 13 is provided on the top of the guardrail 1; a plurality of needle punctures 14 are fixedly connected to the top of the placement plate 13; the plurality of needle punctures 14 are equidistantly distributed on the top of the placement plate 13; a plurality of leakage holes 15 are opened on the top of the placement plate 13; the plurality of leakage holes 15 are equidistantly distributed on the top of the placement plate 13, The flexible plate 16 is fixedly connected to the top of the placement plate 13; the flexible plate 16 is arranged in an arc shape; a plurality of first connecting rods 17 are fixedly connected to a side wall of the flexible plate 16 facing the top of the placement plate 13; the plurality of first connecting rods 17 are equidistantly distributed at the bottom of the flexible plate 16; the ends of the plurality of first connecting rods 17 are fixedly connected to liquid storage capsules 18; the plurality of liquid storage capsules 18 correspond to the positions of the acupuncture 14. When working, the guardrail 1 is set on the top of the horizontal centrifuge, and then the four fixed The horizontal centrifuge can be placed inside the guardrail 1, and then the horizontal centrifuge can be allowed to work normally. When the horizontal centrifuge explodes, it will explode inside the guardrail 1. At this time, with the explosion of the horizontal centrifuge, vibration will occur. At this time, with the vibration, the placement plate 13 on the top of the guardrail 1 can be shaken up. At this time, as the placement plate 13 is shaken up, multiple needles 14 on the top of the placement plate 13 can be synchronously shaken up. At this time, liquid is filled in the interior of multiple liquid storage capsules 18. As the needles 14 come into contact with the liquid storage capsules 18, The acupuncture 14 will puncture the liquid storage capsule 18. At this time, the liquid inside the multiple liquid storage capsules 18 will spray out from the inside of the liquid storage capsules 18, and then fall onto the surface of the placement plate 13. When the liquid falls onto the surface of the placement plate 13, it will leak out from the middle of the multiple leakage holes 15 on the top of the placement plate 13. At this time, the inside of the guardrail 1 can be sprayed. Through the above structure, after the bedroom centrifuge explodes, the liquid can quickly contact the horizontal centrifuge, thereby reducing the fire caused by the explosion of the horizontal centrifuge, thereby causing a secondary explosion.

[0024] like Figures 1 to 3As shown, two support components 2 are fixedly connected to the side wall of the guardrail 1; the two support components 2 are arranged in a U shape; two second connecting rods 21 are fixedly connected to the middle of the support component 2; a plurality of through holes 23 are formed in the top of the flexible plate 16; the end of the second connecting rod 21 is fixedly connected with a hook 22; a plurality of the hooks 22 all penetrate through the through holes 23. During operation, the flexible plate 16 can be erected at a designated position through the cooperation of the support component 2 and the hook 22, and at the same time, the support component 2 can be fixed to the side wall of the guardrail 1. As the flexible plate 16 is hung, the first connecting rod 17 and the liquid storage bag 18 at the bottom of the flexible plate 16 will always move away from the needles 14 on the top of the placement plate 13. Through the above structure, the flexible plate 16 is hung and stretched by the support component 2, which can reduce the loosening of the flexible plate 16, resulting in the direct contact between the liquid storage bag 18 and the needles 14 during the normal operation of the horizontal centrifuge, thereby causing the liquid inside the liquid storage bag 18 to spill out, and finally causing the short circuit of the horizontal centrifuge.

[0025] As Figure 2 and Figure 3 As shown, a pull rope 3 is fixedly connected to the bottom of the placement plate 13; the pull rope 3 penetrates through the guardrail 1 and extends into the interior of the guardrail 1; a weight 31 is fixedly connected to the end of the pull rope 3; the weight 31 is inside the guardrail 1. During operation, the placement plate 13 is pulled and fixed through the cooperation of the pull rope 3 and the weight 31. At this time, when the horizontal centrifuge is working normally, the weight 31 will continuously stretch the placement plate 13, thereby reducing the shaking of the guardrail 1 caused by the operation of the horizontal centrifuge, resulting in the shaking of the needles 14 along with the shaking of the placement plate 13, and the contact between the needles 14 and the liquid storage bag 18. Through the above structure, the placement plate 13 can be continuously stretched, thereby reducing the shaking of the placement plate 13. At the same time, when the horizontal centrifuge explodes, the weight 31 will be shaken off, so that the weight 31 hits the bottom of the placement plate 13. At this time, the needles 14 on the top of the placement plate 13 can contact the liquid storage bag 18 more quickly, so that the liquid inside the liquid storage bag 18 can be quickly ejected and contact the exploding horizontal centrifuge.

[0026] As Figure 4As shown, the side wall of the guardrail 1 is provided with a card slot 4; the card slot 4 is located near the end of the guardrail 1; a card block 41 is detachably installed inside the card slot 4; a collection box 42 is fixedly connected to the end of the card block 41; the collection box 42 is arranged in an arc shape; the top of the card block 41 is fixedly connected to two symmetrically arranged baffles 43. When working, the card block 41 is installed inside the card slot 4. At this time, as the card block 41 is installed, the collection box 42 is also installed. When the liquid inside the liquid storage capsule 18 is sprayed out, a part of the liquid falls into the inside of the guardrail 1 through the leak hole 15, and the horizontal The centrifuge contacts with the horizontal centrifuge, thereby achieving the effect of extinguishing the fire of the horizontal centrifuge. At this time, multiple liquid storage capsules 18 rupture at the same time, and a part of the liquid inside the liquid storage capsules 18 close to the surface will fall to the outside. At this time, a part of the liquid falling to the outside will enter the interior of the collecting box 42 and be collected by the collecting box 42. Subsequently, the liquid entering the collecting box 42 will be blocked by the baffle 43. Through the above structure, the excess liquid accumulated on the top of the placement plate 13 and the liquid inside the liquid storage capsules 18 can be collected and processed in a unified manner, thereby reducing the waste of liquid caused by the liquid falling to the outside.

[0027] like Figures 1 to 3 As shown, the side walls of the flexible plate 16 are fixedly connected to two dustproof plates 5; the two dustproof plates 5 are symmetrically arranged; the ends of the dustproof plates 5 are fixedly connected to the tops of the needle punctures 14. When working, the dustproof plates 5 are installed at the specified position. At this time, as the dustproof plates 5 are installed, the needle punctures 14 and the liquid storage capsule 18 can be blocked inside the dustproof plates 5. Through the above structure, the needle punctures 14 and the liquid storage capsule 18 can be protected, reducing the dust and impurities in the air from being adsorbed on the surface of the needle punctures 14 or the liquid storage capsule 18 for a long time over time, resulting in excessive dust accumulation when an explosion occurs, making it difficult for the needle punctures 14 to destroy the liquid storage capsule 18.

[0028] like Figure 4 As shown, a wire plate 6 is fixedly connected to the end of the card slot 4; the wire plate 6 is symmetrically and inclined. When working, in order to collect the liquid inside the liquid storage capsule 18, the card block 41 needs to be installed inside the card slot 4. At this time, the card block 41 is guided by two wire plates 6, so that the card block 41 can be installed inside the card slot 4 more quickly and accurately. Through the above structure, the position deviation when the card block 41 is installed inside the card slot 4 can be reduced, which makes it difficult to collect the liquid inside the liquid storage capsule 18.

[0029] like Figures 1 to 4 As shown, the placement plate 13 is made of a flexible and deformable material. Through the above arrangement, when the horizontal centrifuge explodes, the placement plate 13 is affected by the vibration and quickly bounces up, so that the needle 14 and the liquid storage capsule 18 are quickly in contact, so as to achieve the effect of extinguishing the fire of the horizontal centrifuge.

[0030] During operation, the guardrail 1 is sleeved on the top of the horizontal centrifuge, and then the four fixing components 12 at the bottom of the guardrail 1 are fixed, so that the horizontal centrifuge can be placed inside the guardrail 1, and then the horizontal centrifuge can work normally. At this time, when the horizontal centrifuge explodes, it will explode inside the guardrail 1. At this time, with the explosion of the horizontal centrifuge, vibration will occur. At this time, with the vibration, the placement plate 13 on the top of the guardrail 1 can be shaken up. At this time, as the placement plate 13 is shaken up, multiple needles 14 on the top of the placement plate 13 can be synchronously shaken up. At this time, liquid is filled in the interior of multiple liquid storage capsules 18. As the needles 14 come into contact with the liquid storage capsules 18, the needles 1 4 will puncture the liquid storage capsule 18, and the liquid in the multiple liquid storage capsules 18 will spray out from the inside of the liquid storage capsules 18, and then fall onto the surface of the placement plate 13. When the liquid falls onto the surface of the placement plate 13, it will leak out from the middle of the multiple leak holes 15 on the top of the placement plate 13. At this time, the inside of the guardrail 1 can be sprayed. The flexible plate 16 can be set at a specified position by the support component 2 and the hook 22, and the support component 2 can be fixed to the side wall of the guardrail 1. As the flexible plate 16 is hung, the first connecting rod 17 at the bottom of the flexible plate 16 and the liquid storage capsule 18 will also be away from the needle puncture 14 on the top of the placement plate 13. Through the coordination of the pull rope 3 and the counterweight 31, the first connecting rod 17 at the bottom of the flexible plate 16 and the liquid storage capsule 18 will also be away from the needle puncture 14 on the top of the placement plate 13. The placement plate 13 is pulled and fixed together. At this time, when the horizontal centrifuge is working normally, the counterweight block 31 will continuously stretch the placement plate 13, thereby reducing the shaking of the guardrail 1 caused by the operation of the horizontal centrifuge, thereby causing multiple needle punctures 14 to shake with the shaking of the placement plate 13, resulting in the contact between the needle punctures 14 and the liquid storage capsule 18. The card block 41 is installed inside the card slot 4. At this time, as the card block 41 is installed, the collecting box 42 is also installed. When the liquid in the liquid storage capsule 18 is sprayed out, a part of the liquid falls into the inside of the guardrail 1 through the leakage hole 15 and contacts the horizontal centrifuge, thereby achieving a fire extinguishing effect on the horizontal centrifuge. At this time, multiple storage The liquid capsule 18 ruptures at the same time, and a portion of the liquid inside the liquid storage capsule 18 close to the surface will fall to the outside. At this time, a portion of the liquid falling to the outside will enter the interior of the collecting box 42 and be collected by the collecting box 42. Subsequently, the liquid entering the interior of the collecting box 42 will be blocked by the baffle 43, and the dustproof plate 5 is installed to the specified position. At this time, as the dustproof plate 5 is installed, the acupuncture 14 and the liquid storage capsule 18 can be blocked inside the dustproof plate 5. In order to collect the liquid inside the liquid storage capsule 18, the card block 41 needs to be installed inside the card slot 4. At this time, the card block 41 is guided by two wire plates 6, so that the card block 41 can be installed inside the card slot 4 more quickly and accurately.
