Technical Field

[0001] The utility model relates to the field of waste recycling, in particular to an oil-water filtering and recovery device for livestock and poultry slaughtering and processing. Background Art

[0004] From the above, it can be seen that the motor is used to drive the worm shaft to rotate, and the worm shaft synchronously drives the worm gear a and the worm gear b to rotate. The rotation of the worm gear b drives the intermittent disk to rotate intermittently through the action of the rotating part and the fixed block, so that multiple carbon sponge strips rotate in sequence and adsorb oil, and the worm gear a drives the turntable to rotate through the connecting shaft, and the turntable drives the oil extrusion plate to move through the action of the connecting rod and the push rod, so that the oil adsorbed on the carbon sponge strip is squeezed out, which is convenient for separating the oil from the sewage. However, there are still the following shortcomings: when the existing technology is used to treat oil and water, the density distribution in the oil and water is not uniform, and a single screening will cause the filter hole to be blocked, which greatly reduces the efficiency of oil and water treatment.

[0005] Therefore, in order to solve the above problems, an oil-water filtering and recovery device for livestock and poultry slaughtering and processing is proposed. Utility Model Content

[0012] Preferably, an extraction pipe is fixedly sleeved on the top of the storage tank, and a return pipe is fixedly sleeved on the top of the storage tank.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model uses the structural design of the screening device to perform fluid stratification on the oil and water through the stratification tank, so that the oil and water with different densities can be separated and purified. The separated oil and water are separated into solid and liquid by the centrifuge. The separated solid phase particles are collected in the collection tank at the bottom of the centrifuge, and the liquid phase is further purified through the inflow pipe. The function of screening by fluid stratification is realized, which solves the problem of uneven density distribution in the oil and water and improves the efficiency of oil and water treatment.

[0015] 2. The utility model uses the structural design of the purification device to further separate the oil and water into solid and liquid through the tube-mounted screen inside the filter bin. The separated solid phase particles re-enter the stratification tank through the reflux pipe, and the liquid phase enters the flotation bin through the purification pipe. Tiny bubbles are generated at the bottom of the flotation bin, and the solid phase particles remaining in the liquid phase are floated up with the tiny bubbles, and the liquid phase is then evolved accordingly, realizing the functions of purifying the liquid phase and recycling the solid phase, solving the problem of reusing waste oil-based oil and water, and improving the adaptability of recycling.

[0024] See also Figure 1-Figure 5As shown, an oil-water filtering and recovery device for livestock and poultry slaughtering and processing includes a vibrating screen 1, a screening device 2, and a purification device 3; the screening device 2 is equipped with a stratification tank 21, the top of the stratification tank 21 is fixedly sleeved with a connecting pipe 24, the other end of the connecting pipe 24 is fixedly sleeved with a storage tank 26, the top of the stratification tank 21 is fixedly sleeved with an extraction pipe 22, the other end of the extraction pipe 22 is fixedly sleeved with a centrifuge 27, the other side of the centrifuge 27 is fixedly sleeved with an inlet pipe 28, and the other end of the inlet pipe 28 is fixedly sleeved with a filter chamber 31;

[0025] During operation, the oil and water used for livestock and poultry slaughtering and processing are stratified through the stratification tank 21 to precipitate the solid phase in the oil and water. The oil and water at the top of the stratification tank 21 are extracted through the connecting pipe 24, so that the oil and water with different densities are separately purified, and the purification efficiency is maximized. Then the solid and liquid phases of the oil and water enter the centrifuge 27 through the extraction pipe 22 to separate the solid and liquid phases of the oil and water. The separated solid and liquid phases of the oil and water are collected in the bottom collection tank of the centrifuge 27, and the liquid phase of the oil and water enters the filter bin 31 through the inflow pipe 28 for further purification.

[0026] Furthermore, a return pipe 23 is fixedly connected to one side of the filter chamber 31, and the other end of the return pipe 23 is fixedly connected to the stratification tank 21;

[0027] During operation, the liquid phase oil and water entering the filter chamber 31 through the inflow pipe 28 has a high solid content and cannot meet the oil and water reuse performance indicators. The solid and liquid are separated by the screen tube inside the filter chamber 31, and the solid phase particles enter the stratification tank 21 through the return pipe 23 for re-screening and stratification. The liquid phase filtered by the filter chamber 31 enters the flotation chamber 33 through the purification pipe 32.

[0028] Furthermore, one side of the back of the vibrating screen 1 is fixedly connected with a delivery pipe 11, the other end of the two delivery pipes 11 is fixedly connected with a concentration pipe 12, and the other end of the concentration pipe 12 is fixedly connected with a stratification tank 21;

[0029] During operation, there are solid particles of different sizes in the oil and water. Different vibrating screens 1 are used with different screens to perform preliminary screening of the oil and water to achieve the highest vibrating screening efficiency.

[0030] Furthermore, a stratification block 29 is fixedly sleeved on the inner wall of the stratification tank 21, and a stirring blade 25 is movably sleeved on the inner wall of the stratification tank 21;

[0031] During operation, the oil and water are separated and sieved by the stratification blocks 29 inside the stratification tank 21 , and the stirring blades 25 stir the oil and water inside, so that the oil and water in the stratification tank 21 are fully mixed with the additives.

[0032] Furthermore, a purification pipe 32 is fixedly connected to one side of the filter chamber 31, and an air flotation chamber 33 is fixedly connected to the other end of the purification pipe 32. An outflow pipe 34 is fixedly connected to the other side of the air flotation chamber 33. The outflow pipe 34 and the air flotation chamber 33 are fixedly connected.

[0033] During operation, the liquid phase separated from the solid by the filter chamber 31 enters the flotation chamber 33 through the purification pipe 32. Micro bubbles are generated at the bottom of the flotation chamber 33, and the solid phase particles remaining in the liquid phase are floated up with the micro bubbles, thereby evolving the liquid phase accordingly.

[0034] Furthermore, an extraction pipe 22 is fixedly sleeved on the top of the storage tank 26, and a return pipe 23 is fixedly sleeved on the top of the storage tank 26;

[0035] During operation, the oil and water of different densities are separated by the stratification tank 21 and the storage tank 26, so that the overall filtration efficiency is higher and the blockage of the pipeline can be effectively avoided.

[0036] Working principle: In embodiment 1, the oil and water used for livestock and poultry slaughtering and processing are preliminarily screened through the vibrating screen 1, and the dehydrated solids in the oil and water continue to move forward until they are removed from the screen. The liquid phase in the oil and water falls through the openings on the screen into the oil and water collecting tank below the vibrating screen 1. The two vibrating screens 1 are used to distinguish and screen solids of different sizes. The liquid phase oil and water are extracted into the inside of the centralizing pipe 12 through the delivery pipe 11 and concentrated. The concentrated liquid phase enters the stratification tank 21 for sedimentation separation to stratify the fluid. After stratification, the oil and water at the top of the stratification tank 21 enters the storage tank 26 through the connecting pipe 24, so that the liquid phase oil and water of different densities are distinguished and purified, and a reagent is added to the oil and water to separate the liquid phase oil and water. At the same time, after separation, it enters the inside of the centrifuge 27 through the extraction pipe 22 for centrifugal solid-liquid phase separation, and the separated solid phase falls into the collection tank at the bottom of the centrifuge 27.

[0037] In the second embodiment, the liquid phase oil and water after centrifugal filtration enters the filter chamber 31 through the inflow pipe 28 and undergoes tubular filtration, so that the solid phase particles remaining in the liquid phase oil and water are further screened. The screened solid and liquid particles return to the stratification tank 21 through the reflux pipe 23 for precipitation, and then enter the centrifuge 27 through the extraction pipe 22 for separation and collection of the solid phase. The screened liquid phase in the filter chamber 31 enters the flotation chamber 33 through the purification pipe 32, and the impurities contained in the liquid phase are floated by generating tiny bubbles at the bottom of the flotation chamber 33, thereby further purifying the liquid phase oil and water.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
