Description

Technical Field

[0001] This utility model relates to the field of fiberglass storage tank manufacturing technology, specifically to a resin homogenization device for fiberglass storage tank production. Background Technology

[0002] The structure of a fiberglass storage tank requires an inner lining layer, which is made of resin, such as epoxy resin or vinyl ester resin. The resin is mixed with a curing agent to form a three-dimensional network structure. The mixture is sprayed onto the surface of the fiberglass storage tank and allowed to air dry and cure to form the inner lining layer. The inner lining layer has the functions of corrosion resistance and resistance to strong acids and alkalis.

[0003] The resin spraying operation is equipped with large spraying equipment and smaller spraying equipment. The large spraying equipment has achieved fully automated spraying. Some manufacturers cannot be equipped with large spraying equipment and mostly use smaller spraying equipment. Small spraying equipment requires manual assistance. The small equipment needs to mix the resin and hardener before spraying it onto the surface of the steel glass storage tank.

[0004] However, in actual use, it was found that the resin and hardener are prone to premature curing due to increased temperature after mixing, which has an adverse effect on the spraying effect.

[0005] To address this, a resin homogenization device for fiberglass storage tank production is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A resin homogenization device for producing fiberglass storage tanks includes a trolley, a reactor, a resin storage tank, a coagulant storage tank, and a controller. The reactor is installed on the top wall of the trolley. The resin storage tank and the coagulant storage tank are located on one side of the reactor. Both the resin storage tank and the coagulant storage tank are equipped with inlet pipes that communicate with the reactor. A cooling device and a spraying device are also provided on the top wall of the trolley.

[0008] The bottom of the trolley is fixedly equipped with multiple support wheels, two of which are swivel wheels.

[0009] The resin placed in the resin storage box can be epoxy resin, vinyl ester resin, etc., and the coagulant can be an amine or acid anhydride curing agent.

[0010] Preferably, the spraying device includes a metering pump, the input end of which is connected to the bottom of the reactor via a pipe, and the output end of which is connected to a spray gun via a pipe.

[0011] Preferably, a second bracket is also fixedly installed on the top wall of the trolley, and a motor is fixedly installed on the second bracket. The output shaft of the motor is fixedly connected to a stirring rod through a coupling. Multiple spiral stirring blades are fixedly connected to the side wall of the stirring rod, and both the stirring rod and the stirring blades extend into the reactor.

[0012] Preferably, the liquid inlet pipe is connected to the top of the reactor, and both the outlet of the resin storage tank and the outlet of the coagulant storage tank are equipped with solenoid valves, which are connected to the controller via wires.

[0013] Preferably, the refrigeration device includes a refrigeration unit and an air inlet pipe. The refrigeration unit is fixedly installed on the top wall of the trolley, and the air inlet pipe is connected to the output end of the refrigeration unit and the other end is connected to the reactor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The trolley is equipped with a reactor, resin storage tank, coagulant storage tank, controller, etc., and a refrigeration device is also installed to supply cold air into the reactor, so that the temperature inside the reactor is kept at a low temperature value, preventing the liquid inside the reactor from solidifying prematurely and improving the processing quality.

[0016] 2. Set a controller to control the volume of liquid entering the reactor, so that the volume of liquid in the reactor is not too large, preventing the liquid at the bottom of the reactor from solidifying prematurely, and allowing the liquid to be smoothly sprayed out from the spray device and evenly adhered to the surface of the fiberglass storage tank.

[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] Please see Figures 1 to 2 This utility model provides a resin homogenization device for the production of fiberglass storage tanks, the technical solution of which is as follows:

[0022] A resin homogenization device for producing fiberglass reinforced plastic (FRP) storage tanks includes a trolley 1, a reactor 3, a resin storage tank 5, a coagulant storage tank 6, and a controller 4. The reactor 3 is mounted on the top wall of the trolley 1. The resin storage tank 5 and the coagulant storage tank 6 are located on one side of the reactor 3. Both the resin storage tank 5 and the coagulant storage tank 6 are equipped with inlet pipes 14 that communicate with the reactor 3. A cooling device and a spraying device are also provided on the top wall of the trolley 1. A bracket 2 is also fixedly mounted on the top wall of the trolley 1, and the controller 4 is fixedly mounted on the bracket 2.

[0023] The selected resin and coagulant are initially in liquid state. Sufficient amounts of liquid resin and liquid coagulant are manually placed into the resin storage tank 5 and the coagulant storage tank 6, respectively. The liquid inlet pipe 14 is connected to the top of the reactor 3. The outlet of the resin storage tank 5 and the outlet of the coagulant storage tank 6 are both equipped with solenoid valves 12. The solenoid valves 12 are connected to the controller 4 via wires.

[0024] The controller 4 controls the opening or closing of the solenoid valve 12 and adjusts the flow rate of the solenoid valve 12.

[0025] like Figure 2 As shown, the spraying device includes a metering pump 11. The input end of the metering pump 11 is connected to the bottom of the reactor 3 through a pipe, and the output end of the metering pump 11 is connected to a spray gun through a pipe. The spraying is used to spray the mixed liquid onto the fiberglass storage tank to be sprayed, so that it can be naturally dried and solidified on the fiberglass storage tank to form an inner lining layer.

[0026] A bracket 2 7 is also fixedly installed on the top wall of the trolley 1. A motor 8 is fixedly installed on the bracket 2 7. The output shaft of the motor 8 is fixedly connected to a stirring rod 15 through a coupling. Multiple spiral stirring blades 13 are fixedly connected to the side wall of the stirring rod 15. Both the stirring rod 15 and the stirring blades 13 extend into the reactor 3.

[0027] like Figure 2As shown, the side of the stirring rod 15 is relatively sharp, which can smoothly cut through the interior of the mixed liquid, making the mixture more thoroughly mixed.

[0028] The motor 8 is started by the controller 4, and the speed of the output shaft of the motor 8 is set so that the stirring rod 15 stirs the mixed liquid and the two liquids are fully mixed.

[0029] The liquid inlet pipe 14 is connected to the top of the reactor 3. The outlet of the resin storage tank 5 and the outlet of the coagulant storage tank 6 are both equipped with solenoid valves 12. The solenoid valves 12 are connected to the controller 4 via wires.

[0030] The controller 4 is equipped with a flow control program and a timing program. The flow control program controls the flow rate and opening and closing time of the solenoid valve 12, thereby setting the volume of liquid entering the reactor 3 to prevent the liquid from entering the reactor 3 at one time from being too large and solidifying prematurely at the bottom.

[0031] The refrigeration device includes a refrigeration unit 9 and an air inlet pipe 10. The refrigeration unit 9 is fixedly installed on the top wall of the trolley 1. The air inlet pipe 10 is connected to the output end of the refrigeration unit 9 and the other end is connected to the reactor 3.

[0032] The air is drawn in by the refrigeration process and then cooled down before being pumped into reactor 3. The cold air is used to cool the mixed liquid, preventing it from solidifying prematurely due to temperature rise and improving processing quality.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
