Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a slaughterhouse wastewater pretreatment device. Background Art

[0002] Slaughterhouse wastewater comes from pen washing, leaching, slaughtering and other factory floor washing, scalding, dissection, food processing, animal residues, blood, etc. The feces left in the animal body and the blood produced during the slaughtering process contain a high amount of ammonia nitrogen. If it is not treated, it will seep into the ground or flow into the river, which will naturally damage the water on which humans depend for survival, causing the growth of blue algae, and thus causing large-scale deaths of fish and shrimp in the water.

[0003] In the prior art, slaughterhouse wastewater is usually treated by a flotation machine. The flotation machine is a dissolved air system that produces a large number of fine bubbles in the water, causing the air to attach to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make it float on the water surface, thereby achieving solid-liquid separation. The water treatment equipment is used in both slaughterhouse wastewater and urban sewage treatment.

[0004] In the current existing technology, the flotation machine on the market is usually composed of a frame, an air valve, a conveying pipe, and a motor. The motor on the top is used for operation. The filtered liquid in the filtered liquid storage box is sent into the wastewater treatment box through the high-pressure air valve. The internal slaughter wastewater is dissolved and filtered through the wastewater treatment box, and then the treated wastewater is discharged through the water outlet. However, after a long period of operation, there will be a certain amount of residue in the wastewater treatment box. If the slaughter wastewater continues to flow in and squeeze the water inlet pipe, there will be a safety hazard. Therefore, a slaughterhouse wastewater pretreatment device is proposed to address the above problems. Utility Model Content

[0007] Preferably, two groups of fixing ears are installed on the top of the front panel, a rack is installed below the front panel, a gasket is installed below the rack, and four groups of gaskets are installed at the bottom to protect the rack.

[0008] Preferably, a wastewater treatment box is installed on the inner side of the front panel, and support plates are installed on both sides of the wastewater treatment box. An adapter is installed at one end of the wastewater treatment box, and a fastening plate is installed under the pressure dial, which is connected to the high-pressure air pump through the adapter.

[0009] Preferably, one end of the adapter is connected to a liquid spray pipe, the other end of the liquid spray pipe is equipped with a high-pressure air pump, an external fixing ring is installed on the circumferential surface of the high-pressure air pump, two groups of metal hoses are installed on the surface of the high-pressure air pump, and a control panel is installed on the surface of the front panel, and the overall treatment of slaughter wastewater is completed by operating the control panel.

[0010] Preferably, a connecting block is installed at the other end of the metal hose, and the connecting block is installed on the surface of the filtrate storage box. Two sets of auxiliary support rods are installed below the wastewater treatment box, and the filtrate is delivered to the interior of the wastewater treatment box through the two sets of metal hoses.

[0012] The utility model is beneficial in that:

[0013] The utility model provides a slaughterhouse wastewater pretreatment device. In order to solve the problem that after a long period of operation, there will be a certain amount of residue in the wastewater treatment box. If the slaughter wastewater continues to flow in and squeeze the water inlet pipe, a safety hazard will occur. By installing a pressure relief device at the end of the water inlet pipe, when the pointer of the pressure dial reaches the warning line, the pressure relief valve will discharge the excess pressure through two groups of air outlet hoses by rotating the top handle. By discharging the excess pressure in the water inlet pipe, the load on the water inlet pipe is reduced and the service life of the machine is improved. At the same time, two groups of auxiliary support rods are installed on both sides of the bottom of the frame to prevent the top wastewater treatment box from colliding with the bottom.
