Description

Technical Field

[0001] This utility model belongs to the field of fiberglass storage tank processing technology, and in particular relates to a fiberglass storage tank spraying device. Background Technology

[0002] Due to their excellent corrosion resistance, lightweight, high strength, and long service life, fiberglass storage tanks are used in the chemical industry. The operation of a fiberglass storage tank spraying device to spray the inner and outer walls of the tank is part of the fiberglass storage tank processing procedure.

[0003] The fiberglass storage tank spraying device mainly consists of paint tank, pipeline, material pump, spraying unit, hydraulic cylinder, hydraulic rod and clamping plate.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing fiberglass storage tank spraying equipment uses hydraulic cylinders and hydraulic rods to extend and adjust the spacing between clamps until the clamps limit the position of the fiberglass storage tank, thus effectively preventing the tank from shifting during spraying and allowing for better spraying. However, the fiberglass storage tank needs to be disassembled to adjust its position, which makes it inconvenient to spray the entire tank. Furthermore, the clamps can obstruct the view of the tank, further hindering the overall spraying process.

[0006] 2. Existing fiberglass storage tank spraying equipment uses a material pump to guide the pigment from the paint tank into the nozzle, which then sprays the pigment onto the inner and outer walls of the fiberglass storage tank. However, this method is not convenient for spraying both the inner and outer walls of the fiberglass storage tank simultaneously, thus increasing the spraying time and reducing spraying efficiency.

[0007] To address these issues, we provide a fiberglass storage tank spraying device. Utility Model Content

[0008] The purpose of this utility model is to provide a fiberglass storage tank spraying device. By setting up a tensioning component, the fiberglass storage tank body can be easily rotated and adjusted, thereby facilitating comprehensive spraying of the fiberglass storage tank body. Furthermore, by controlling the adjustable hydraulic cylinder, the distance between the support plate and the inner wall of the fiberglass storage tank body can be adjusted, thus preventing the support plate from obstructing the spraying of the inner wall of the fiberglass storage tank body. Additionally, by setting up a spraying component and controlling the pump, the inner and outer walls of the fiberglass storage tank body can be sprayed simultaneously, thereby accelerating the efficiency of spraying the inner and outer walls of the fiberglass storage tank body. This solves the technical problems mentioned in the background art of existing fiberglass storage tank spraying devices.

An adjusting hydraulic cylinder connected to the periphery of the connecting column has an adjusting hydraulic rod connected to its end. The end of the adjusting hydraulic rod away from the adjusting hydraulic cylinder is connected to the inner wall of the support plate. An internal spraying assembly is also provided inside the fiberglass storage tank body. A U-shaped pipe is inserted inside the fiberglass storage tank body, with one half inside and the other half outside. Spray nozzles are connected in a rectangular array on the inner wall of the pipe.

[0011] The present invention is further configured such that base plates are symmetrically arranged at both ends of the fiberglass storage tank body, a bracket is hinged to the upper surface of the base plate, and self-locking casters are connected to the lower surface of the base plate in a rectangular array.

[0014] The present invention is further configured such that sleeves are symmetrically fixed to the two inner side walls of the bracket, and the upper end of the guide rod sleeved inside the sleeve penetrates the inner top of the bracket.

[0015] The present invention is further configured such that a rotating shaft is connected to the middle of the outer side wall of the positive plate connected to the outer side wall of the positive ear plate, a motor is connected to the end of the rotating shaft away from the positive plate, a reinforcing block connected to the peripheral side wall of the rotating shaft is connected to the outer side wall of the positive plate, and the lower surface of the support rotatably connected to the peripheral side wall of the rotating shaft is connected to the upper end of the lifting hydraulic rod, and the lower surface of the support is connected to the upper end of the guide rod.

[0016] The present invention is further configured such that a connecting shaft is connected to the middle of the outer side wall of the reverse plate connected to the outer side wall of the reverse plate, a reinforcing block connected to the peripheral side wall of the connecting shaft is connected to the outer side wall of the reverse plate, and a guide roller is symmetrically rotatably connected inside the support box provided below the connecting shaft.

This facilitates comprehensive spraying of the inner and outer walls of the FRP storage tank body. Furthermore, by activating the adjustable hydraulic cylinder, when the adjustable hydraulic rod retracts, the support plate does not contact the inner wall of the FRP storage tank body, thereby eliminating the obstruction of the inner wall of the FRP storage tank body by the support plate, and thus enabling more comprehensive spraying of the inner wall of the FRP storage tank body.

[0040] Example 3

[0041] Please see Figure 1 , Figure 2 and Figure 3 Based on specific embodiments one and two, a spraying assembly 3 is provided. The spraying assembly 3 includes a mounting plate 301, a paint tank 302, a support plate 303, a pump 304, a connecting pipe 304a, a connecting pipe 304b, a pipe 305, a nozzle 305a, and a sealing block 306. The pump 304 is operated to introduce the pigment inside the paint tank 302 into the pipe 305. The two sets of nozzles 305a spray the pigment inside the pipe 305 onto the inner and outer walls of the fiberglass storage tank body 1, thereby simultaneously spraying the inner and outer walls of the fiberglass storage tank body 1. This speeds up the spraying efficiency of the fiberglass storage tank body 1 and avoids the repeated disassembly and assembly of the fiberglass storage tank body 1 by the workers, reducing the amount of operation required when spraying the fiberglass storage tank body 1.

[0042] Specifically, a self-locking caster wheel 101a is connected to the lower surface of the mounting plate 301, and a paint tank 302 is connected to the upper surface of the mounting plate 301.

[0044] The operation process of this embodiment is as follows: The operator starts the pump 304 to introduce the pigment inside the paint tank 302 into the pipe 305. The pigment inside the pipe 305 is sprayed onto the inner and outer walls of the fiberglass storage tank body 1 through the nozzle 305a. When one of the support plates 205 obstructs the nozzle 305a from spraying pigment onto the inner wall of the fiberglass storage tank body 1, the adjusting hydraulic cylinder 206 on the corresponding support plate 205 is activated. The adjusting hydraulic rod 206a retracts, and the support plate 205 does not contact the inner wall of the fiberglass storage tank body 1, thereby allowing the nozzle 305a to spray pigment onto the inner wall of the fiberglass storage tank body 1 normally. After the spraying is completed, the corresponding adjusting hydraulic cylinder 206 is activated again, and the adjusting hydraulic rod 206a extends, and the support plate 205 contacts the inner wall of the fiberglass storage tank body 1.
