Septic tank for sewage

The present invention relates to a septic tank provided with a check valve on the partition walls formed inward, and more particularly, to bury the septic tank in the ground and fill it with water to prevent earth pressure and injury during initial installation. The partitions formed therein are configured to not be damaged.

In general, a septic tank is a tank buried in the ground to purify sewage used in homes and buildings. The tank is divided into a decayed tank, an oxidizing tank, and a disinfection tank. will be.

5 is a schematic view showing a conventional septic tank, which will be described below with reference to this.

A plurality of partitions 1 are provided inward so that the sewage may be sequentially cleaned in the ground, and a plurality of compartments 1a are formed, and an inlet 11 through which the sewage flows into the upper side of each compartment 1a. Is formed, and the upper portion of the partition (1) shows that the connection hole 12 for connecting each compartment (1a) is penetrated.

Therefore, when the sewage is filled from the first compartment to the connection hole formed in the upper part of the partition, the sewage is moved to the next compartment, and when the sewage is filled to the connection hole, the sewage is moved to the next compartment again.

In addition, each compartment may be configured to have characteristics such as a decay tank and an oxidizing tank disinfection tank to sequentially purify sewage.

However, when the partitions are broken, the sewage stored in the compartments having the respective characteristics is mixed, and thus the problem of inability to purify the sewage occurs.

FIG. 6 is a view illustrating a state in which water is initially introduced into a conventional septic tank, and FIG. 6A is a schematic view showing a state in which first water is supplied to a first compartment, and FIG. 6B is a schematic view showing a state in which water is filled in a first compartment.

When the septic tank is buried in the ground for the first time, a space is formed inward so that the septic tank may be damaged by earth pressure or the septic tank may be injured in rainy weather. To fill.

When water flows in from the upper side of the first first compartment 1a, the potential energy of the water is increased due to the drop, so that the water is filled in the compartment 1a and continuously exerts impact on the lower side of the partition 1 so that the partition 1 There is a risk of cracking or breakage in the weld zone.

When the water is filled to some extent, since a large force is applied to the partition wall 1 by the load of the water, there is a possibility that a crack or breakage occurs in the welded portion of the partition wall 1.

Therefore, after the septic tank was initially buried in the ground, the barrier ribs were damaged when a certain amount of water was filled in order to prevent damage due to earth pressure and injury during rain.

In addition, if the bulkhead is damaged when the septic tank is buried in the ground and a certain amount of water is filled into each compartment, the septic tank needs to be recovered and repaired again. there was.

The present invention is designed to solve the above problems, and is provided with a check valve on each partition wall to prevent damage to the partition wall when the first septic tank is buried in the ground and then filled with water in each compartment. For the purpose.

In addition, by using a check valve that is opened and closed by the elasticity of the spring, the purpose of the check valve is not operated unless the level difference between each compartment is large.

In order to achieve the above object, the present invention has a plurality of partitions provided inward so that the sewage may be sequentially buried in the ground, and a plurality of compartments are formed, and an inlet through which sewage flows into the upper side of each compartment. Is formed, and in a normal purification tank in which connection holes penetrating each compartment are formed in an upper portion of the partition wall, a through hole connecting the compartment is formed in the middle lower side of the partition wall, According to the characterized in that the check valve for discharging the water is provided.

The check valve may include a body having one or more inlet holes toward the water inlet and one or more outlet holes on the side from which the water is discharged, and water provided inside the inlet hole. It characterized in that the packing is made of opening and closing through the spring to be discharged to the discharge hole side.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce the same.

1 is a schematic view showing a septic tank according to the present invention, in which a plurality of partitions 1 are provided inward so that the sewage may be sequentially cleaned, and a plurality of compartments 1a are formed, and each compartment ( In a conventional septic tank having an inlet 11 through which sewage flows into the upper side of 1a, and a connection hole 12 penetrating each compartment 1a is formed in an upper portion of the partition 1, The through hole 13 which connects the said compartment 1a is formed in the middle lower part of the partition 1, and the check valve 14 which discharges water according to a water pressure is provided in the inside.

In order to prevent the septic tank from being damaged by earth pressure or floating the septic tank in case of rain, after the septic tank is initially buried in the ground, a certain amount of water is filled in each compartment, and the check valve is provided in each partition wall. When the water flowing into the first compartment is filled up to a certain amount, the check valve is opened by the water pressure and the water is transferred to the second compartment. When the water is filled to some extent, the water is filled again into the next compartment by the tee check valve. will be.

Therefore, by distributing water evenly to the compartments, since the water filled in both sides supports the partition wall, the force applied to the partition wall can be canceled by the load of water, thereby solving the problem of breaking the partition walls. It is.

FIG. 2 is an enlarged view of a part A according to FIG. 1, and FIG. 3 is an operation state diagram of the check valve according to FIG. 2, wherein the check valve 14 has at least one inlet hole 142a and water toward the water inflow side. The body 141a in which one or more discharge holes 143a are formed on the discharge side and water introduced into the inlet hole 142a side are provided in the discharge hole 143a. It shows that the packing 145a is opened and closed through the spring 144a to be discharged to the side.

When the water pressure of the water drawn to the inflow side is increased, the packing 145a is pushed by the water pressure into the inflow hole 142a, and the discharge hole 143a which is blocked by the packing 145a is opened to the other side. Water is discharged.

However, the packing 145a is equipped with a spring 144a to not only prevent water from flowing backward, but also to prevent the packing 145a from being pushed back unless the water level difference is large.

Therefore, the check valve is activated when water is filled while the first compartments 1a are empty, but when the septic tank is used after the water is filled up in each compartment 1a, each compartment 1a is not filled. Since the water level is not greatly increased due to the sewage, the sewage can be prevented from moving to each compartment through the check valve.

In addition, the check valve may be formed by inserting a plurality of through holes 13 at the same height of the bulkheads 1 and inserting them into the through holes 13 according to the size of the septic tank. It could be.

However, since this is a device necessary only for the first use, it may be better to use only a check valve that does not damage the partition wall 1 rather than using a plurality of check valves.

4 is an operating state diagram showing an embodiment according to FIG. 3, wherein the check valve 14 includes a hinge 141b fixed to an inner upper portion of the through hole 13 and a lower side of the hinge 141b. It shows that it consists of a locking step (142b) which is provided to the lower side to be caught on the end.

In addition, the locking step 142b is mounted with a spring 143b connected to the lower end of the hinge 141b to apply a restoring force to the hinge 141b.

When the spring 143b is mounted on the hinge 141b so that the water pressure on the inflow side becomes greater than the elasticity of the spring 143b, the spring 143b 'is extended and the hinge 141b' is opened to open the water. This is discharged to the other compartment.

However, when the pressure on the inlet side drops or the water on the outlet side is moved to the inlet side, the hinge 141b is in close contact with the latching jaw 142b by the spring 143b, thereby preventing backflow. .

In addition, since the spring 143b is mounted, the water level does not move to the discharge side because the hinge 141b is fixed by the force of the spring 143b unless the level difference is large.

Therefore, in filling a certain amount of water after the first septic tank is buried in the ground, since the water is not moved to the respective compartments by using the connection holes formed on the upper sides of the compartments, It can offset the load.

Thus, when the septic tank tank is installed, it is possible to reduce the cost of repairing the partition wall.

As described above, the present invention provides a check valve on each partition wall to prevent the partition wall from being damaged when the first septic tank is buried in the ground and then filled with water in each compartment. If damaged, the problem of having to recover and repair the septic tank is solved, thereby minimizing economic repair costs.

In addition, by using a check valve that is opened and closed by the elasticity of the spring, the check valve is not operated unless the level difference between each compartment is large, so that the partition wall is blocked so that filthy water does not move to the other compartment through the check valve during use. It will have the effect.
