Description

Technical Field

[0001] The utility model relates to the technical field of firecracker production, in particular to a firecracker production wastewater treatment pool. Background Art

[0002] The production of firecrackers involves the production of gunpowder. During the production of gunpowder, some wastewater and waste liquid will be generated when grinding and mixing the gunpowder raw materials. These wastes are polluting and will be centrally filtered and treated. In the wastewater pretreatment, these wastewaters need to be precipitated so that the heavier particulate pollutants such as sand and metal powder contained in them can be settled to the bottom of the pool. Most of the existing sedimentation tanks are one-piece. Due to the compact structure of the one-piece sedimentation tank, the residence time of the sludge may not be fully considered during the design. If the sludge stays in the pool for too long, the organic matter in the sludge will cause corruption, produce gas, and cause the sludge to float to the water surface. This not only affects the sedimentation effect, but may also cause the effluent water quality to deteriorate. In view of this, a firecracker production wastewater treatment pool is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a firecracker production wastewater treatment pool, including a pool tank, a bottom control valve is arranged at the bottom of the pool tank, an output control valve is arranged on one side of the pool tank, and an inner water injection cylinder is arranged in the middle of the pool tank.

[0004] Furthermore, a vortex ring is provided on the inner wall of the inner water injection cylinder, and a matching water injection pipe is provided on the top of the inner water injection cylinder.

[0005] Furthermore, the bottom height of the water injection pipe is slightly higher than the bottom of the inner water injection cylinder.

[0006] Furthermore, the bottom of the tank is in a triangular bucket shape, an upper convex ring is arranged on the top of the tank, and an outer convex ring is also arranged on the outer side of the upper convex ring.

[0007] Furthermore, an inner limit plate is provided on the inner wall of the middle part of the tank, a matching connecting plate is connected to the inner limit plate, and a liquid inlet hole in a circular array for blocking suspended matter in the waste liquid is also provided on the connecting plate.

[0008] Furthermore, the connection port of the control valve is also provided with a matching output pipe connected to the inner wall of the tank.

[0009] Beneficial effect: After the wastewater generated by firecracker production is injected into the water injection pipe, the liquid level in the inner water injection cylinder begins to gradually rise, and at the same time, driven by the vortex-shaped vortex ring, the rising water body is forced to rotate and form a vortex, which can achieve the effect of promoting the downward sedimentation and separation of dirt. After the inner water injection cylinder is filled, it spreads outward through the inner wall of the inner water injection cylinder to the bottom of the tank. The suspended matter contained in the wastewater flowing to the bottom of the tank is retained on the connecting plate, and then the liquid level of the tank gradually rises and gradually spreads to the upper convex ring, and these suspended matter will finally spread to between the upper convex ring and the outer convex ring due to the rising liquid level, so as to further solve the problem of suspended matter generating bubbles and affecting the wastewater sedimentation effect.

[0016] In a specific embodiment, one end of the water injection pipe 401 is connected to a water pump, and the other end is used to inject wastewater generated by firecracker production. After the water injection pipe 401 is injected with wastewater generated by firecracker production, the liquid level in the inner water injection cylinder 4 begins to gradually rise. At the same time, driven by the vortex-shaped vortex ring 402, the rising water body is forced to rotate and form a vortex, which can achieve the effect of promoting the downward sedimentation and separation of dirt, and form a secondary water injection.

The suspended matter contained in the wastewater flowing to the bottom of the tank 1 is retained on the connecting plate 5, and then the liquid level of the tank 1 gradually rises and gradually spreads to the upper convex ring 102. These suspended matter will finally spread to between the upper convex ring 102 and the outer convex ring 103 due to the rising liquid level, forming a tertiary water injection to solve the problem of suspended matter generating bubbles and affecting the wastewater sedimentation effect, and further improve the sedimentation effect of the device.

[0017] Furthermore, the bottom control valve 2 can control the discharge of the waste residue remaining at the bottom of the tank 1, and the inner water injection cylinder 4 can be clamped and limited by wire or clamping plates to facilitate the removal and cleaning of the wastewater after sedimentation.
