Off-site assembled container manufacturing method, bag-type pressure drain tank and liquid level controller

Abstract

The invention discloses an off-site assembled container manufacturing method, a bag-type pressure drain tank and a liquid level controller. The method for manufacturing the container and the water tank body comprises the following steps of: manufacturing middle containments at least annularly provided with an open edge and corresponding end covers on a production workshop according to the requirement respectively, and overlapping a plurality of middle containments and end covers inside and outside, or packing and storing the middle containments and the end covers; after being transferred to each use destination, connecting the open edge ends and the ends of the middle containments and the end covers or connecting through connecting members to form a container body by assembly; and arranging a fluid storage elastic bag or / and a bag joint, a filter element and / or an inner supporting frame and the liquid level controller consisting of a power supply master controller and a secondary controller connected by a power supply connecting wire on the corresponding positions. The method solves the problems of large storage space occupied by the container body, high cost and the like in the conventional one-time forming production method. The invention provides the bag-type pressure drain tank with strong non-bearing pressure drainage capability, low cost and cleaner water and the liquid level controller with low cost, more reliable and safer performance and the like.

Description

technical field [0001] The invention relates to a container and its manufacturing method, in particular to the field of a water supply tank and a liquid level controller. Background technique [0002] In the production technology of various containers in the prior art, especially various water supply tanks and bladder accumulators, except for super large-scale welding and installation on site, the container body is concentrated in the production workshop after the production is completed. , and then transported to the user's place for installation and use, which has many shortcomings and problems as follows: because the inner space of the finished container body takes up too much space, especially for large or extra-large containers, It occupies more space in the warehouse, especially the transportation vehicle, resulting in high storage and transportation costs. The farther the transportation distance and the larger the volume, the higher the freight and even exceed the co...

Problems solved by technology

[0002] In the production technology of various containers in the prior art, especially various water supply tanks and bladder accumulators, except for super large-scale welding and installation on site, the container body is concentrated in the production workshop after the production is completed. , and then transported to the user's place for installation and use, which has many shortcomings and problems as follows: because the inner space of the finished container body takes up too much space, especially for large or extra-large containers, It occupies more space in the warehouse, especially the transportation vehicle, resulting in high storage and transportation costs

However, if it needs to be installed in high-rise buildings, the hoisting is also troublesome or difficult. Large-scale containers can only be welded on site, which greatly increases the cost and the time of production and installation.

However, as the same type or the same product is set up in different regions for production, it will not be able to form a production scale, and cannot produce scale effects and benefits. It will not only increase the investment and management costs of production equipment and workshops, but also cause a great waste of resources. , that is to say, it also increases the production cost, especially the sales cost of export transportation to other distant countries is even higher

And if it is to produce the bladder type pressure-discharge container that does not need the container body to directly store the fluid, it is produced by the prior art method, and there is also unnecessary waste of production equipment investment and its production mode is more backward

And if it is to manufacture extra-large containers, the existing buckle-pressing machinery and equipment are also difficult to adapt to problems such as

That is, most of the existing production methods for containers that need to be moved, installed and used are not scientific enough; the existing high-level water supply tanks also include the "multi-purpose fluid pressure discharge device" that the applicant previously applied for. and other containers, they all have the above-mentioned same problems that the above-mentioned production method is not scientific enough, and the overall cost of increasing production equipment investment and transportation costs is high.

However, the non-encapsulated high-level water supply water tank in the prior art also has a drainage pressure that is only a height differential pressure, so that the water supply pressure on the floors near the water tank is too low, and its water storage is connected to the atmosphere, resulting in secondary pollution of water. , At the same time, it does not have the function of filtering to improve the water quality and make it more hygienic.

And its water level control is not safe and reliable, including the existing automatic liquid level controller composed of various sensing elements and circuits, which not only has problems such as complex structure, high cost, poor stability and high failure rate. When problems such as component failures occur, there are safety issues such as unattended unattended equipment, unable to stop inflow, etc.

Including the float power switch control type, when the switch fails, the power supply of the water pump and / or electric valve cannot be disconnected, resulting in excessive expansion of the container body and / or outflow, wasting resources

However, the "liquid level control device" previously applied by the applicant also has a part installed outside the elastic bag at the lower part of the container, which has the disadvantage of poor follow-up adaptability after permanent deformation of the bag body.

For a simple, low-priced non-capsule or bladder water supply tank for household use, if a controller with a flow meter or a complex detection sensor circuit processing type is used to control the water intake, the cost will be multiplied. It is not economical to increase the level, it is an unnecessary waste of resources

The above-mentioned problems, including existing high-level pools and water towers, also exist
