Description

Catering wastewater treatment equipment

technical field

The utility model relates to a device used in the field of oily wastewater treatment, in particular to a catering wastewater treatment device.

Background technique

The traditional method for the discharge of catering wastewater from underground catering kitchens is to first conduct oil-water separation treatment through a grease trap or a grease separator before discharging. The sludge deposited in the water inlet grill box of the existing integrated oil separation equipment cannot be discharged, and the slick oil always accumulates in the water inlet grill box and cannot smoothly enter the oil-water separation box. The mesh of the basket-type grill is easily stuck by grease Attached blockage, resulting in frequent overflow of the water inlet grill box, affecting the surrounding environment, and the equipment cannot be used normally. The grease in the water inlet grill box needs to be cleaned manually on a regular basis, which increases the daily management intensity of the equipment.

The disadvantages of these practices are: 1. The water inlet grill box often overflows, which affects the surrounding environment, and the equipment cannot be used normally; 2. The floating oil in the water inlet grill box always accumulates and cannot smoothly enter the oil-water separation box; 3. Set the influent sludge deposition, the accumulated sludge gradually enters the oil-water separation box, affecting the effect of oil-water separation. These disadvantages will directly affect the daily maintenance operation of the oil separation equipment, increase the maintenance cost and time of the equipment, and affect the long-term stable operation of the equipment.

Utility model content

In order to overcome the above-mentioned defects in the prior art, the utility model discloses a catering wastewater treatment equipment.

Technical scheme of the utility model:

Catering waste water treatment equipment, including water inlet pipe, basket grille, water inlet grille box, sludge deposition box, sludge collection and discharge device, diversion tank, oil-water separation box, oil collection and oil discharge device, heating device, overflow channel The device, the water outlet pipe, the control box, the mud collecting barrel, and the oil collecting barrel are characterized in that:

The oil-water separation box is fixedly installed, and the upper cover of the oil-water separation box is connected to the oil collection barrel through the oil collection and discharge device, and a heating device is installed, and a control box is installed on one side of the oil-water separation box;

The water inlet grid box on the left side of the oil-water separation box is connected with a water inlet pipe, and a basket-type grille is fixedly installed inside it. The mud deposition box is connected to the mud collecting bucket through the mud collecting and discharging device;

The upper side wall of the water inlet grid box is connected to the oil-water separation box and the water outlet pipe through an overflow device.

The catering wastewater treatment equipment is characterized in that: the bottom of the sludge deposition tank is a conical bottom to facilitate sludge deposition, and a diversion tank is provided in the sludge deposition tank, the diversion tank is fixedly installed, and the diversion The tank utilizes the water level difference and the drainage effect to allow the oil and water flow to be drained and improve the effect of oil and water separation.

The catering wastewater treatment equipment is characterized in that: the mud collecting and discharging device and the oil collecting and discharging device both adopt the siphon principle and regularly open the valve to output the sludge and oil to the mud collecting barrel and the oil collecting barrel.

The above-mentioned catering wastewater treatment equipment is characterized in that: the top of the oil-water separation box adopts an asymmetrical conical structure, the oil and water are naturally stratified by gravity, and the floating oil on the water surface is easier to accumulate, and is discharged to the Oil barrels.

The catering wastewater treatment equipment is characterized in that: the heating device is sealed and connected to the top plate of the oil-water separation box through perforated welding.

Advantage of the utility model:

The oil-water separation box of the utility model is equipped with a heating device to prevent oil from congealing and agglomerating, and the oil collection and discharge are smoother. The structure of the whole machine is integrated, and the structure is compact and unique. Easy to install and disassemble, small footprint, convenient maintenance and repair, high sewage discharge efficiency.

Detailed ways

Referring to the accompanying drawings, when the utility model equipment is working, the catering waste water first enters by itself through the water inlet pipe 1, and flows into the basket-type grille 2 through the pipeline, and the particles and impurities in the waste water are intercepted, and the waste water after separating the impurities enters the water inlet grid The grill box 3, the water inlet grill box 3 and the sludge deposition box 4 are separated by an intermediate partition, the bottom of the box is connected, and the bottom adopts a conical structure. The sludge in the waste water is deposited in the sludge deposition box 4, and the sludge is regularly opened and discharged The valve and the sludge pass through the sludge collection and discharge device 5, and the sludge is discharged to the sludge collection bucket 13 by using the siphon principle. Grease on the water surface passes through the sludge deposition tank 4 to set up a diversion groove 6, and utilizes the water level difference and drainage effect to allow the oil-water flow to be diverted, and the oil-water mixture enters the oil-water separation tank 7 along the diversion groove 6, and the top adopts an asymmetric cone Shaped structure, oil and water are naturally stratified by gravity, and the oil slick on the water surface is easier to gather, and is discharged to the oil collection barrel 14 by regularly opening the oil release valve.

The water flow after the oil-water separation is discharged through the outlet pipe 11.

When water overflow occurs in the water inlet grill box 3, it can flow into the oil-water separation box 7 through the overflow device 10, and be discharged by the overflow of the water outlet pipe 11. The overflow device 10 also has a ventilation function to ensure the normal flow and safety of the overall equipment water flow.
