Description

Technical Field

[0001] This utility model relates to the field of o-phenylphenol technology, specifically to a buffer tank for o-aminophenol production that is easy to fix. Background Technology

[0002] o-Phenylphenol is a widely used organic chemical product, extensively applied in sterilization and preservation, dyeing auxiliaries and surfactants, as well as as a stabilizer and flame retardant in the synthesis of new plastics, resins, and polymer materials. In the production process of o-aminophenol, buffer tanks are typically used to store and regulate key raw materials such as o-nitrophenol. The regulating function of the buffer tank ensures a stable material supply in the reactor, avoiding production fluctuations caused by insufficient or excessive material supply. However, existing buffer tanks used in o-phenylphenol production are prone to displacement, which can affect operational stability. Therefore, a more easily fixed buffer tank for o-aminophenol production is proposed, designed to facilitate precise positioning, prevent displacement and shaking during production, and further improve the stability of o-phenylphenol production. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a buffer tank for o-aminophenol production that is easy to fix, facilitating the positioning of the buffer tank, preventing displacement and shaking during production, and further improving the stability of o-aminophenol production.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buffer tank for o-aminophenol production that is easy to fix, comprising a buffer tank, with multiple sets of support legs fixedly installed at the bottom of the buffer tank, each set of support legs having a caster wheel installed at the bottom, and a positioning mechanism provided at the bottom of the support legs, and further comprising multiple sets of fixing mechanisms adapted to the positioning mechanisms and requiring to be cast into the ground, the positioning mechanism including a guide column that can be raised and lowered, and a chain fixedly installed at the bottom of the guide column, the fixing mechanism including a fixing sleeve arranged vertically with an inner diameter consistent with the guide column, the inner top of the fixing sleeve having a transition ring groove with a flat top and an arc bottom, the bottom of the fixing sleeve having an inner vertical column whose top extends into the transition ring groove, the top of the inner vertical column having a transition convex arc surface, the distance between the transition convex arc surface and the transition ring groove being greater than the diameter of the chain link and less than the length of the chain link.

[0007] Preferably, a guide sleeve is fixedly connected to the support leg, the guide post can be vertically slidably fitted inside the guide sleeve, and an adjusting strip is fixedly installed on the top of the guide post. The top of the guide sleeve is circumferentially provided with a vertical guide groove and a top groove that cooperate with the guide sleeve. When the adjusting strip is rotated to align with the vertical guide groove, the adjusting strip slides down the vertical guide groove to the bottom, and the bottom of the guide post can penetrate into the fixed sleeve. A pressing mechanism is also provided above the guide post to press the adjusting strip into the top groove.

[0008] Preferably, the clamping mechanism includes a limiting frame fixedly installed on the support leg, a vertical rod slidably fitted on the limiting frame, a lower pressing block fixedly installed at the bottom of the vertical rod, an upper limiting block fixedly installed at the top of the vertical rod, a compression spring sleeved on the vertical rod, the two ends of the compression spring being fixedly connected to the lower pressing block and the limiting frame respectively, and a sliding piece rotatably connected to the bottom of the lower pressing block, which can make integral contact with the guide post and the adjusting strip.

[0009] Preferably, a support plate is fixedly installed at both the top and bottom of the fixing sleeve.

[0010] Preferably, the multiple sets of support legs, the multiple sets of positioning mechanisms, and the multiple sets of fixing mechanisms are all configured as at least three sets.

[0011] Preferably, the number of casters installed at the bottom of each set of support legs is set to two sets and symmetrically distributed on both sides of the support legs.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a buffer tank for o-aminophenol production that is easy to fix, and has the following beneficial effects:

[0014] This easily secured buffer tank for o-aminophenol production utilizes multiple positioning and fixing mechanisms. During use, the fixing mechanisms are cast onto the ground, mirroring the layout of the positioning mechanisms. Multiple casters then move the buffer tank above the fixing mechanisms, aligning them vertically. The guide posts in each positioning mechanism are then slowly and vertically lowered, allowing the chain to first fall into the fixing sleeve. The chain, through the cooperation of the inner vertical post, the transition convex surface, and the transition ring groove, engages with the transition convex surface and the transition ring. The gap in the support bracket descends, eventually causing the bottom of the guide column to fall into the interior of the fixing sleeve. Thus, if the buffer tank as a whole tends to sway laterally during operation, the guide column, chain, fixing sleeve, transition ring groove, and inner vertical column work together. When there is a tendency to bounce rapidly upwards, the chain can quickly fix it between the top of the transition ring groove and the transition convex surface without the need for separate parts. The operation is simple. This easy-to-fix buffer tank for o-aminophenol production facilitates the positioning of the buffer tank, avoids displacement and shaking of the buffer tank during production, and further improves the stability of o-phenylphenol production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A buffer tank for o-aminophenol production that is easy to fix includes a buffer tank 1. Multiple sets of support legs 2 are fixedly installed at the bottom of the buffer tank 1. Each set of support legs 2 is equipped with casters 3 at the bottom. The bottom of the support legs 2 is provided with a positioning mechanism. The buffer tank 1 also includes multiple sets of fixing mechanisms that are adapted to the positioning mechanisms and need to be cast into the ground. The positioning mechanism includes a guide column 5 that can be lifted and moved. A chain 6 is fixedly installed at the bottom of the guide column 5. The fixing mechanism includes a fixing sleeve 7 that is vertically arranged and has the same inner diameter as the guide column 5. A transition ring groove 8 with a flat top and an arc bottom is provided at the top of the fixing sleeve 7. An inner vertical column 9 with its top extending into the transition ring groove 8 is fixedly installed at the bottom of the fixing sleeve 7. A transition convex arc surface 10 is provided at the top of the inner vertical column 9. The distance between the transition convex arc surface 10 and the transition ring groove 8 is greater than the diameter of the chain link 6 and less than the length of the chain link.

[0023] Specifically, a guide sleeve 4 is fixedly connected to the support leg 2, and a guide post 5 can be vertically slidably fitted inside the guide sleeve 4. An adjusting strip 11 is fixedly installed on the top of the guide post 5. The top of the guide sleeve 4 has a vertical guide groove 12 and a top groove 13 that engage with the guide sleeve 4. When the adjusting strip 11 is rotated to align with the vertical guide groove 12, the adjusting strip 11 slides down the vertical guide groove 12 to the bottom, and the bottom of the guide post 5 can penetrate into the fixed sleeve 7. Above the guide post 5, there is also a groove that can press the adjusting strip 11 into the top groove. The clamping mechanism inside 13, by raising the adjusting strip 11 at the top of the guide column 5 above the guide sleeve 4 and overcoming the pressure of the clamping mechanism, can align the adjusting strip 11 with the vertical guide slide 12 or the top slot 13 by rotating the adjusting strip 11. When aligned with the vertical guide slide 12 and the adjusting strip 11 is moved downward, the guide column 5 can fall into the fixed sleeve 7. When aligned with the top slot 13, under the action of the clamping mechanism, the adjusting strip 11 can be locked in the top slot 13, thereby allowing the guide column 5 and the chain 6 to be raised into the guide sleeve 4.

[0024] Specifically, the clamping mechanism includes a limiting frame 14 fixedly installed on the support leg 2. A vertical rod 16 is vertically slidably fitted on the limiting frame 14. A lower pressing block 15 is fixedly installed at the bottom of the vertical rod 16, and an upper limiting block 17 is fixedly installed at the top of the vertical rod 16. A compression spring 18 is sleeved on the vertical rod 16. The two ends of the compression spring 18 are fixedly connected to the lower pressing block 15 and the limiting frame 14, respectively. The bottom of the lower pressing block 15 is rotatably connected to a sliding piece that can make overall contact with the guide post 5 and the adjusting strip 11. Through the sliding piece, the guide post 5 and the adjusting strip 11 can rotate relative to the lower pressing block 15 by pushing against the sliding piece, thereby avoiding the compression spring 18 being twisted laterally. When the adjusting strip 11 is locked in the top locking groove 13, under the action of the rebound force of the compression spring 18, the adjusting strip 11 is locked in the top locking groove 13, preventing it from rotating and making it stably locked in the top locking groove 13.

[0025] Specifically, a support plate 19 is fixedly installed on both the top and bottom of the fixed sleeve 7. The support plate 19 facilitates the pouring of the fixed sleeve 7 onto the ground. The support plate 19 at the top is flush with the top surface of the fixed sleeve 7, and the top surface of the support plate 19 at the bottom is fixedly installed on the bottom surface of the fixed sleeve 7.

[0026] Specifically, each of the multiple sets of support legs 2, multiple sets of positioning mechanisms, and multiple sets of fixing mechanisms is set to at least three sets. Setting them to three sets improves the stability of the support, while setting them to four or more sets can reduce the supporting force of each set of support legs 2.

[0027] Specifically, the number of casters 3 installed at the bottom of each set of support legs 2 is set to two sets and symmetrically distributed on both sides of the support legs 2 to improve the stability of the support.
