Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic storage tanks, in particular to a glass fiber reinforced plastic vertical chemical storage tank. Background Art

[0002] FRP storage tank is a high-performance storage tank made of glass fiber and resin. It combines the strength of glass fiber and the adhesion of resin, and has the characteristics of light material, high mechanical strength and strong corrosion resistance. Therefore, it is widely used in food grade storage, fire storage, petrochemical raw material storage and other fields.

[0003] FRP tanks used to store chemical raw materials are called chemical tanks. Chemical tanks are usually fixed on the ground. Chemical raw materials stored in chemical tanks for a long time will be stratified and precipitated. The components with higher density will be deposited at the bottom of the chemical tank under the action of their own weight. This phenomenon will not only make the concentration of chemical raw materials discharged from the chemical tank uneven, but also increase the risk of blockage of the discharge port of the chemical tank.

[0004] In the prior art, there are related literature reports on technical solutions for solving the uneven concentration of chemical raw material components discharged from chemical storage tanks. For example, adding a stirring device at the bottom of the chemical storage tank, but this structure can only improve the uniformity of the components of the chemical raw materials within a certain range, and cannot improve the current situation of sediment accumulation at the bottom of the chemical storage tank. Utility Model Content

[0005] In view of this, the utility model aims to propose a fiberglass vertical chemical storage tank, which can diffuse the chemical raw material components with higher density deposited at the bottom of the chemical storage tank to various parts of the chemical storage tank, thereby reducing the risk of blockage of the chemical storage tank discharge port and improving the uniformity of the various components of the chemical raw materials discharged from the chemical storage tank.

[0007] The utility model discloses a glass fiber reinforced plastic vertical chemical storage tank, comprising:

[0008] Tank;

[0021] Furthermore, the outer surface side wall of the tank body is provided with reinforcing ribs along the circumferential direction, and the reinforcing ribs are arranged in a plurality and evenly distributed along the axial direction of the tank body.

[0022] Furthermore, the driving assembly is arranged on the top of the tank body, and a guardrail is arranged on the top of the tank body, and the guardrail surrounds the outer side of the driving assembly.

[0023] Compared with the prior art, the utility model has the following advantages:

[0024] The glass fiber reinforced plastic vertical chemical storage tank described in the utility model has a tank body that supports and limits the installation of the moving parts and the drain pipe; the tank body is the main structure that functions to store chemical raw materials; the drain pipe is connected to the inside of the tank body, and can discharge the chemical raw materials stored in the tank body to the outside; the stop valve installed on the drain pipe plays a role in controlling the on-off of the drain pipe; the moving part will lift the sediment deposited at the bottom of the tank body to the top of the tank body during the rising process, and evenly disperse the sediment to various parts of the tank body during the descending process.

[0047] The present embodiment relates to a glass fiber reinforced plastic vertical chemical storage tank, which adopts a movable part that can slide along the axial direction of the chemical storage tank. During the sliding and lifting process of the movable part, the sediment deposited at the bottom of the chemical storage tank is evenly dispersed to various places in the chemical storage tank, thereby achieving the purpose of reducing the risk of blockage of the discharge port of the chemical storage tank and improving the uniformity of various components of chemical raw materials discharged from the chemical storage tank.

[0048] In terms of overall structure, the FRP vertical chemical storage tank of this embodiment includes a tank body 1, a moving part 2 and a drain pipe 3. The moving part 2 can be driven to slide inside the tank body 1 and fits with the inner wall of the tank body 1. One end of the drain pipe 3 is connected to the bottom of the inner side of the tank body 1, and the other end is connected to the outer side of the tank body 1. A stop valve 301 is installed at one end of the drain pipe 3 located outside the tank body 1.

[0049] As configured above, during the sliding of the moving part 2 along the axial direction of the tank body 1, the sediment deposited at the bottom of the tank body 1 will be lifted to the top of the tank body 1 during the rising of the moving part 2, and will be evenly diffused to various places in the tank body 1 during the descending of the moving part 2. The drain pipe 3 plays a discharge role, and can discharge the chemical raw materials stored in the tank body 1 to the outside of the tank body 1. The stop valve 301 installed on the drain pipe 3 can be used to control the opening and closing of the drain pipe 3.

A metal bottom shell can be added to the bottom of the tank body 1 to facilitate its lifting and support. In order to facilitate the addition of chemical raw materials into the tank body 1, a delivery pipe 101 is installed on the side wall of the tank body 1. The delivery pipe 101 is a section of a circular pipe connected to the inside of the tank body 1, and the delivery pipe 101 can be made of the same material as the tank body 1. The delivery pipe 101 is located at one end of the outer side of the tank body 1, and a sealing plate 102 is installed by flange connection. The sealing plate 102 is detachably mounted on the delivery pipe 101 by a plurality of bolts, and forms a blockage for the delivery pipe 101. The sealing plate 102 can be made of metal, and a handle is installed on the sealing plate 102 by welding. In order to further improve the bearing capacity and mechanical strength of the tank body 1, reinforcing ribs 103 are arranged circumferentially on the side wall of the tank body 1. The reinforcing ribs 103 play a role in limiting and supporting the side wall of the tank body 1. The reinforcing ribs 103 can be made of the same material as the tank body 1, or can be made of metal. The reinforcing ribs 103 are arranged to be evenly distributed along the axis of the tank body 1. In this embodiment, the number of reinforcing ribs 103 is three. In order to improve safety, a guardrail 104 is arranged on the top of the tank body 1. The guardrail 104 is arranged along the circumference of the top edge of the tank body 1. The guardrail 104 protects the operator from working at height.

[0052] It is worth noting that, in order to ensure that the movable part 2 can smoothly slide relative to the tank body 1, a guide hole 201 is provided on the movable part 2 along its thickness direction. The guide hole 201 plays a diversion role, and can supply chemical raw materials to flow during the relative sliding of the movable part 2 and the tank body 1. In order to improve the smoothness of the movement of the movable part 2, the guide hole 201 can be a long strip waist-shaped hole parallel to the edge of the movable part 2. The guide hole 201 is set to a plurality of uniformly distributed circumferentially along the edge of the movable part 2, and the number of the guide holes 201 in the present embodiment is ten. In order to lift as much sediment as possible to the top of the tank body 1, the movable part 2 is constructed as a plate-like shape that fits the inner wall of the tank body 1.

[0053] In order to improve the smoothness and stability of the moving part 2 during its movement, the moving part 2 is sleeved on the portion of the drain pipe 3 located on the inner side of the tank body 1. The portion of the drain pipe 3 located on the inner side of the tank body 1 extends from the bottom to the top of the tank body 1 along a direction parallel to the axis of the tank body 1, passes through the top of the tank body 1, and then extends from the top to the bottom of the outer side of the tank body 1. The portion of the moving part 2 sleeved on the drain pipe 3 extends toward both ends along the axis direction of the drain pipe 3 to form an extension portion 202. The extension portion 202 fits the outer wall of the drain pipe 3, and the drain pipe 3 can guide and limit the moving part 2 when the moving part 2 and the tank body 1 slide relative to each other, thereby achieving the purpose of improving the smoothness and stability of the moving part 2 during its movement.
