Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to a chemical production dripping device. Background Technology

[0002] Chemical production reactions are usually carried out in a reactor. During the production process, various chemical agents (such as auxiliary agents) are usually added to the reactor. Some chemical agents need to be mixed and reacted before being added to the reactor to form a mixed reactant, which is then added to the reactor to assist in chemical production.

[0003] CN220003957U discloses a chemical production dripping device, including a mixing tank, a reaction vessel below the mixing tank, a dripping pipe at the lower end of the mixing tank, a valve on the dripping pipe, an inlet pipe on the reaction vessel, the dripping pipe being able to be inserted into the inlet pipe, a stirring assembly inside the dripping pipe, the stirring assembly including a rotatable shaft with multiple blades on the shaft, a top cover fixed to the upper end of the mixing tank, a through hole on the top cover, and the shaft being rotatably mounted on the top cover.

[0004] The specific working principle of the chemical production dripping device disclosed in the aforementioned publication number CN220003957U is as follows: a mixing tank is set up, and a dripping pipe is set at the lower end of the mixing tank to connect with the liquid inlet pipe on the reactor. A valve is set on the dripping pipe to control the sealing and conduction of the dripping pipe. In use, the valve is first closed, and a stirring component is set up to accelerate the mixing efficiency of the chemical reagents, ensuring that the chemical reagents are fully mixed and reacted in the mixing tank first. Then, the valve is opened to drip the mixed chemical reagents into the reactor to complete the preparation of the chemical product.

[0005] Currently, the chemical production dripping device disclosed in the aforementioned publication number CN220003957U requires the valve handle on the dripping pipe to be manually rotated in order to regulate and control the sealing or conduction of the dripping pipe. If it is subjected to external impact, the valve handle will rotate, which will affect the normal sealing or conduction effect of the dripping pipe.

[0006] In addition, the chemical production dripping device disclosed in the above-mentioned publication number CN220003957U has its bottom support legs distributed relatively close together, which not only reduces the operable space of the bottom discharge pipe of the reactor, but also makes the reactor relatively tall and thin, which is prone to shaking and instability due to the vibration force of the stirring and mixing process. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a chemical production dripping device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Design a chemical production dripping device, including a reaction vessel, a discharge pipe and an inlet pipe on the reaction vessel, a flange on the inlet pipe, a dripping pipe and a fixing plate on the flange, a valve stem and a mixing tank on the dripping pipe, a top cover on the mixing tank, a stirring assembly and a feeding pipe on the top cover, a valve handle on the valve stem, and a positioning cylinder on the fixing plate, with a cylinder rod slidably connected to the positioning cylinder;

[0010] A pressure-regulating seat is provided on the cylinder rod, and an opening slot is provided on the pressure-regulating seat. A damping block is provided in the opening slot.

[0011] The reactor is equipped with anti-sway support legs, which are provided with stabilizing rings and mounting plates. The mounting plates have mounting holes and arc surfaces, and are provided with anti-slip and corrosion-resistant layers.

[0012] Furthermore, the fixing plate and the positioning cylinder are a set, and there are two sets arranged symmetrically. The positioning cylinder is fixedly mounted on the fixing plate, and the cylinder rod is slidably connected to the fixing plate laterally.

[0013] Furthermore, the pressure-regulating seat is generally trapezoidal in shape, and the top view of the opening slot is arc-shaped and vertically penetrates the pressure-regulating seat.

[0014] Furthermore, the damping block is an arc-shaped structure, and the inner diameter of the arc-shaped structure on the top view of the damping block is the same as the outer diameter of the valve handle on the top view.

[0015] Furthermore, the anti-sway support legs and mounting plates are a set, totaling six sets arranged in a circle. The anti-sway support legs are generally bent structures, and the stabilizing rings are disposed between the anti-sway support legs.

[0016] Furthermore, the mounting holes are four symmetrically arranged and vertically penetrate the mounting plate, and the arc surfaces are located at the four corners of the mounting plate.

[0017] Furthermore, the anti-slip and corrosion-resistant layer is uniformly coated along the lower end surface of the mounting plate, and the anti-slip and corrosion-resistant layer is a silicate coating with a thickness of two to three hundred micrometers.

[0018] The chemical production dripping device proposed in this utility model has the following advantages:

[0019] 1. This utility model features a symmetrical pneumatic damping positioning and clamping structure on the flange between the inlet pipe and the dripping pipe. When the valve handle is manually rotated to adjust and control the dripping pipe for blocking or opening, the positioning cylinder can be activated to achieve symmetrical lateral sliding and stably dampen and clamp the valve handle, preventing the valve handle from rotating due to external impacts. This effectively ensures the normal and stable blocking effect of the dripping pipe.

[0020] 2. This utility model provides anti-sway support legs that are inclined outward and evenly arranged in a circular pattern on the side wall of the reactor. Then, it provides a stabilizing ring and a mounting plate structure with mounting holes on the anti-sway support legs. This not only effectively increases the operable space of the discharge pipe at the bottom of the reactor, but also avoids the phenomenon of swaying and instability caused by the overall height and slenderness of the reactor.

[0021] 3. This utility model further improves the anti-slip and corrosion resistance between the mounting plate and the preset base plate by setting an anti-slip and corrosion-resistant layer structure at the bottom of the mounting plate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-5 A chemical production dripping device includes a reaction vessel 1, a discharge pipe 11 and an inlet pipe 12 on the reaction vessel 1, a flange 13 on the inlet pipe 12, a dripping pipe 2 and a fixing plate 4 on the flange 13, a valve stem 21 and a mixing tank 3 on the dripping pipe 2, a top cover 31 on the mixing tank 3, a stirring assembly 32 and a feeding pipe 33 on the top cover 31, a valve handle 22 on the valve stem 21, and a positioning cylinder 41 on the fixing plate 4, with a cylinder rod 42 slidably connected to the positioning cylinder 41.

[0030] A constant pressure seat 5 is provided on the cylinder rod 42. An opening slot 50 is provided on the constant pressure seat 5. A damping block 51 is provided in the opening slot 50.

[0031] The reactor 1 is equipped with anti-sway support legs 6, which are equipped with stabilizing rings 61 and mounting plates 7. The mounting plates 7 have mounting holes 71 and arc surfaces 72, and are provided with anti-slip and corrosion-resistant layers 73. Some of the structures described in this patent are common structures of chemical production dripping devices and are existing technologies. Some existing structures are not drawn or labeled and need not be described in detail. For relevant content of chemical production dripping devices disclosed in publication number CN220003957U in the background technology of this patent, please refer to the relevant content of chemical production dripping devices.

[0032] The fixed plate 4 and the positioning cylinder 41 are a set, and there are two sets symmetrically arranged. The positioning cylinder 41 is fixedly set on the fixed plate 4, and the cylinder rod 42 slides laterally with the fixed plate 4 to achieve a stable damping clamping effect of electric and pneumatic symmetrical clamping of the valve handle 22.

[0033] The pressure-regulating seat 5 has a trapezoidal structure, and the top view of the opening slot 50 is an arc-shaped structure that vertically penetrates the pressure-regulating seat 5. The trapezoidal structure of the pressure-regulating seat 5 has high stability and improves the lateral clamping force.

[0034] The damping block 51 has an overall arc-shaped structure and is made of NBR nitrile rubber, which has high elasticity and damping friction.

[0035] The inner diameter of the arc-shaped structure of the damping block 51 in top view is the same as the outer diameter of the valve handle 22 in top view, so as to achieve matching damping positioning clamping sleeve of the outer wall surface of the valve handle 22.

[0036] The anti-sway support leg 6 and the mounting plate 7 are a set, and there are a total of six sets arranged in a circle. The anti-sway support leg 6 has a bent structure. The stabilizing ring 61 is set between the anti-sway support legs 6. The anti-sway support leg 6 and the stabilizing ring 61 are made of hard alloy steel, which has high strength and improves the structural stability between the anti-sway support leg 6 and the stabilizing ring 61, while also improving the stable support for the reactor 1.

[0037] The mounting holes 71 are four symmetrically arranged and vertically penetrate the mounting plate 7. The arc surfaces 72 are set at the four corners of the mounting plate 7. The arc surfaces 72 prevent the four corners of the 90-degree mounting plate 7 from causing scratches to personnel.

[0038] The anti-slip and corrosion-resistant layer 73 is uniformly coated along the lower end surface of the mounting plate 7. The anti-slip and corrosion-resistant layer 73 is a silicate coating with a thickness of two to three hundred micrometers. The silicate coating has excellent anti-slip and corrosion resistance and is suitable for extremely harsh environments.

[0039] Working method: The chemical reagent liquid for chemical production is put into the mixing tank 3 through the feeding pipe 33. Then, the stirring component 32 is started to stir and mix the chemical reagent liquid. The valve handle 22 can be held and rotated. Combined with the valve rod 21, the flow of the dripping pipe 2 can be adjusted and controlled. The stirred chemical reagent liquid can then be fed into the reaction vessel 1 through the liquid inlet pipe 12 for chemical production. Then, the valve handle 22 is rotated again to block the dripping pipe 2 (existing technology).

[0040] At this time, the positioning cylinder 41 can be activated, which drives the cylinder rods 42 on both sides to slide laterally along the preset sliding holes on the fixed plate 4, thereby driving the pressure seat 5 to slide laterally closer. When the pressure seats 5 on both sides clamp the outer wall of the valve handle 22 symmetrically and stably through the damping blocks 51, the positioning cylinder 41 is stopped. This will prevent the valve handle 22 from being rotated due to external collisions, thus ensuring the normal and stable sealing effect of the drip tube 2.

[0041] Furthermore, after the mounting plate 7 is stably installed with the lower preset base plate (not shown, existing technology for bottom installation) through preset bolts and mounting holes 71, the anti-sway support legs 6, which are set to be inclined outward and evenly arranged in a circular pattern, combined with the stabilizing ring 61 structure, not only improve the operable space of the bottom discharge pipe 11 of the reactor 1, but also avoid the phenomenon of swaying and instability due to the overall height and slenderness of the reactor 1.

[0042] In addition, by setting an anti-slip and corrosion-resistant layer 73 structure at the bottom of the mounting plate 7, the anti-slip and corrosion-resistant properties between the mounting plate 7 and the preset base plate below are further improved.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
