Description

Technical Field

[0001] This application relates to the technical field of chemical equipment, and particularly to a feeding device for the production of petroleum additives. Background Art

[0002] Petroleum additives are a class of chemical substances used to improve the performance and additional functions of petroleum products. During the petroleum processing and application processes, the use of petroleum additives can improve the quality of petroleum products, facilitate the implementation of production processes, and meet market demands. In addition, petroleum additives can also reduce environmental pollution and energy consumption, and extend the service life of petroleum products.

[0003] The production process of petroleum additives mainly includes several key steps such as raw material preparation, reaction preparation, and product refining. The reaction preparation stage mainly involves carrying out appropriate reactions on the proportioned different raw materials in a reactor to produce the required petroleum additive products.

[0004] For example, as one of the additives, the main raw materials required for the production of demulsifiers include surfactants, solvents, and auxiliary agents. Auxiliary agents include stabilizers, pH regulators, etc., which are used to adjust the performance and stability of demulsifiers. And stabilizers also have different types, such as lead salts, metal soaps, etc. Powdered raw materials accumulate in the storage tank and are easily affected by moisture and caking. When added to the reactor in this way, they cannot come into full contact with solvents, etc., which affects the reaction efficiency, increases the reaction time, and prolongs the production time.

[0005] Therefore, this application provides a feeding device for the production of petroleum additives to avoid the extrusion and caking of powdered raw materials in the storage tank 1, which affects the feeding state and reaction state.

[0006] Application Content

[0007] The purpose of this application is to solve the problems existing in the prior art and propose a feeding device for the production of petroleum additives.

[0008] To achieve the above purpose, this application adopts the following technical solutions:

[0009] A feeding device for the production of petroleum additives includes a suspended storage tank. The lower end of the storage tank is constricted and is provided with a feeding pipe. A first motor is mounted on the upper port of the storage tank. An electric telescopic rod is installed on the output shaft of the first motor. A rotating shaft is installed on the extending end of the electric telescopic rod. A sealing cover cooperating with the feeding pipe is embedded on the side wall of the rotating shaft close to the bottom wall of the storage tank. A plurality of vibrating rods are annularly arranged on the side wall of the sealing cover. A material control component is provided below the feeding pipe to prevent overfeeding.

[0010] Preferably, the material control component includes a feeding cylinder communicated with the lower port of the feeding pipe. A screw conveyor is rotatably installed in the feeding cylinder. The screw conveyor is driven by a second motor installed at the end of the feeding cylinder.

[0011] Preferably, the feeding cylinder is inclined upward.

[0014] Preferably, the lower end of the rotating shaft extends into the blanking pipe, and a stirring fan is sleeved on the side wall of the rotating shaft in the blanking pipe.

[0015] Compared with the prior art, the present application provides a feeding device for the production of petroleum additives, which has the following beneficial effects:

[0016] In this device, the blanking pipe is closed by an electric telescopic rod. Before blanking, the rotating shaft is first driven by the first motor to rotate to stir the powder materials, which is combined with the vibration wave of the vibrating rod to break up the agglomerated powder materials, making the powder materials loose, so as to avoid blanking blockage and prevent the insufficient contact between the agglomerated powder materials and solvents, etc., which affects the reaction time and state. When blanking, the electric telescopic rod contracts and the cover rises, and the powder materials can leak and be fed from the blanking pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will be combined with the accompanying drawings in the embodiments of the present application Figures 1-5 to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0025] To solve the problems existing in the prior art, this embodiment provides a feeding device for petroleum additive production, including a hoisted material tank 1. The lower end of the material tank 1 is closed and provided with a feeding pipe 12. A material control component is arranged below the feeding pipe 12. A first motor 7 is mounted on the upper port of the material tank 1. An electric telescopic rod 8 is installed on the output shaft of the first motor 7. A rotating shaft 9 is installed on the extending end of the electric telescopic rod 8. A sealing cover 10 cooperating with the feeding pipe 12 is embedded on the side wall of the lower end of the rotating shaft 9 close to the bottom wall of the material tank 1. A plurality of vibrating rods 11 are annularly arranged on the side wall of the sealing cover 10.

[0026] Details of the principle of this embodiment:

[0027] A feeding device for petroleum additive production, including a hoisted material tank 1: A suspension rail 2 is provided directly above the reactor for additive production. An electrically driven moving seat 3 is installed on the suspension rail 2 (a driving wheel buckled on the suspension rail 2 is arranged on the moving seat 3, and the driving wheel is driven by a motor fixed on the moving seat 3). A connecting member 4 is hoisted at the lower end of the moving seat 3. A plurality of hanging ears are arranged around the connecting member 4. A steel wire suspension rope 5 is hung on each hanging ear. The end of each steel wire suspension rope 5 is hooked with a connecting seat. All the connecting seats are jointly connected with a collar 6 through fasteners. The collar 6 is sleeved on the side wall of the upper port of the material tank 1 through fasteners. So that the material tank 1 can be displaced as required, and the use is more flexible.

[0028] The lower end of the material tank 1 is in a sunken closed design facing downward along the axis. The bottom end of the closed material tank 1 is communicated with a feeding pipe 12. Two symmetrical cross beams are installed on the upper port of the material tank 1 through fasteners. A first motor 7 is installed on the cross beam through fasteners. An electric telescopic rod 8 is fixedly installed on the output shaft of the first motor 7. A rotating shaft 9 is fixedly installed on the extending end of the electric telescopic rod 8. A sealing cover 10 is embedded on the side wall of the lower end of the rotating shaft 9 close to the bottom wall of the material tank 1. The sealing cover 10 is directly above the upper end pipe orifice of the feeding pipe 12. The caliber of the sealing cover 10 is larger than the caliber of the lower port of the feeding pipe 12. A plurality of vibrating rods 11 are annularly arranged on the side wall of the sealing cover 10. The structure and principle of the vibrating rod 11 refer to the concrete stirring rod.

[0029] A material control component is arranged below the feeding pipe to prevent overfeeding.

[0030] During use, the powdery raw materials are filled in the material tank 1. When feeding, first start the first motor 7 and the vibrating rod 11. The first motor 7 drives the electric telescopic rod 8 and the rotating shaft 9 to rotate synchronously. The rotating shaft 9 drives the sealing cover 10 to rotate, and the sealing cover 10 drives all the vibrating rods 11 to rotate, stirring the raw materials, which can break up the raw materials, make the raw materials looser, and the feeding more smooth. During the stirring process, the vibrating rod 11 transmits its vibration wave to the powder material, making the powder material in contact with the vibrating rod 11 looser and further eliminating the phenomenon of powder caking.

[0031] After stirring for a certain time, the electric telescopic rod 8 contracts, and the rotating shaft 9 drives the sealing cover 10 to rise, and the upper port of the feeding pipe 12 is exposed. Under the action of the material control component, a specified amount of powder material is injected into the reactor.

[0032] This device closes the feeding pipe 12 through the electric telescopic rod 8. Before feeding, first drive the rotating shaft 9 to rotate through the first motor 7 to stir the powder material, cooperate with the vibration wave of the vibrating rod 11, break up the caked powder material, make the powder material loose, which can avoid feeding blockage and prevent the insufficient contact between the caked powder material and the solvent, etc., from affecting the reaction time and state.

[0033] Preferably, a tension sensor is provided on the connecting piece 4, and the tension sensor is electrically connected to the first motor 7 and the electric telescopic rod 8. The tension sensor is based on the following principle: the elastic body (elastic element, sensitive beam) generates elastic deformation under the action of an external force, so that the resistance strain gauge (conversion element) pasted on its surface also generates deformation accordingly. After the resistance strain gauge is deformed, its resistance value will change (increase or decrease), and then through the corresponding measurement circuit, this resistance change is converted into an electrical signal (voltage or current), thus completing the process of converting the external force into an electrical signal. In this way, as the powder material gradually discharges from the feeding pipe 12, the weight of the material tank 1 decreases, the tension applied to the tension sensor becomes smaller, the elastic deformation amount decreases, the resistance value of the resistance strain gauge changes, and after being converted into an electrical signal, the feeding amount can be known, and then the electric telescopic rod 8 is extended to block the feeding pipe 12, and cooperate with the material control component, so as to more accurately achieve the purpose of quantitative feeding.

[0034] In a further embodiment of this solution, in this embodiment, a specific structure of the material control component capable of controlling the feeding amount is provided: the material control component includes a feeding cylinder 15 communicated with the lower port of the feeding pipe 12, and a screw conveyor 17 is rotatably installed in the feeding cylinder 15, and the screw conveyor is driven by a second motor 16 installed at the end of the feeding cylinder 15.

[0035] Details of the principle of this embodiment:

[0036] The material control assembly includes a feeding cylinder 15 communicated with the lower port of the blanking pipe 12. One end of the feeding cylinder 15 is open and the other end is sealed. The sealed end of the feeding cylinder 15 is fixedly installed with a second motor 16 through a fastener. The second motor 16 is wirelessly connected to the controller of the tension sensor. The output shaft of the second motor 16 is inserted into the feeding cylinder 15. A screw conveyor 17 is fixedly installed on the output shaft of the second motor 16. A rotating seat is arranged above the open end of the feeding cylinder 15. The other end of the driving shaft of the screw conveyor 17 is rotatably installed on the rotating seat.

[0037] When the electric telescopic rod 8 contracts, the rotating shaft 9 rises, the upper port of the blanking pipe 12 opens, and the powder falls into the feeding cylinder 15. With the start of the second motor 16 and the drive of the screw conveyor 17 to rotate, the powder is conveyed to the port part of the feeding cylinder 15 along with the rotation of the screw conveyor 17 and falls into the reactor from the open end of the feeding cylinder 15. When the added amount of the powder reaches the required amount, the second motor 16 is turned off, the screw conveyor 17 stops rotating, and the separated material stays in the feeding cylinder 15. Due to the self-sealing property of the screw conveyor 17 and the feeding cylinder 15, no further feeding will occur.

[0038] In a further embodiment of this solution, the feeding cylinder 15 is arranged obliquely upward, and the second motor 16 is installed at the sinking end of the feeding cylinder 15. The open end of the feeding cylinder 15 is arranged obliquely upward, and is hermetically matched with the screw conveyor 17, so that after the screw conveyor 17 stops, the separated material near the open end of the feeding cylinder 15 can still stay stably in the feeding cylinder 15.

[0039] In a further embodiment of this solution, a bent pipe 18 is detachably installed at the upturned end of the feeding cylinder 15. One end of the bent pipe 18 communicates with the feeding cylinder 15, and the other end of the pipe mouth is vertically downward. The purpose of adding the bent pipe 18 is to prevent the powder from leaking out of the open end of the feeding cylinder 15 and falling outside the reactor along the outer wall of the feeding cylinder 15.

[0040] In a further embodiment of this solution, a conical cover 13 is buckled on the upper end of the cover 10. Cooperating with the vibration effect of the vibrating rod 11, it avoids the powder staying on the upper end face of the cover 10.

[0041] In a further embodiment of this solution, the lower end of the rotating shaft 9 extends into the blanking pipe 12, and a stirring fan 14 is sleeved on the side wall of the rotating shaft 9 in the blanking pipe 12. After the cover 10 rises with the contraction of the electric telescopic rod 8, the upper port of the blanking pipe 12 opens, and the powder falls into the blanking pipe 12 and is further impacted and dispersed by the rotating stirring fan 14, further solving the problem of powder caking. The dimension of the rotating shaft 9 extending into the blanking pipe 12 satisfies that when the cover 10 abuts against the upper port of the blanking pipe 12, the lower end of the rotating shaft 9 does not extend into the feeding cylinder 15; when the cover 10 rises, the stirring fan 14 is still in the blanking pipe 12.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the application concept of the present application, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
