Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater pretreatment device. Background Technique

[0002] Industrial production plays an indispensable role in modern life. Due to the development of industrial production, it brings many conveniences to modern life. However, at the same time, the production is also accompanied by inevitable waste treatment problems. Among them, it is necessary to treat industrial floating oil wastewater and remove the floating oil on the surface of the sewage. The reason is that the floating oil covering the surface of the water or processing fluid will cause the water quality and liquid to deteriorate and stink, and it also affects the accuracy of the processed workpieces. Therefore, it is necessary to pre-treat the floating oil in the wastewater, so that it can be recycled through subsequent treatment of industrial floating oil wastewater.

[0003] In the prior art, when treating industrial floating oil wastewater, manual oil fishing is adopted. This method requires a lot of manpower and material resources, and is time-consuming and laborious. Then, a belt-type oil-water separator is used for oil fishing work. It has a high degree of automation, is fast in treating industrial floating oil and does not require manual guarding of the machine. However, the oil removal belt of this belt-type oil-water separator is fixedly set and cannot be adjusted according to the height of the liquid level. Secondly, the width of the belt surface of the oil removal belt is fixed, and the oil removal area is fixed, making it difficult to adjust the oil removal speed in a timely manner.

[0004] Therefore, we make improvements and propose an industrial wastewater pretreatment device. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An industrial wastewater pretreatment device of the utility model includes a wastewater tank. An elevating mechanism is installed in the inner cavity of the wastewater tank. An infrared sensor is installed on the elevating mechanism, and an oil floating collection component is also installed on the elevating mechanism.

[0007] Rectangular grooves are symmetrically opened in the middle of the side wall surface of the inner cavity of the wastewater tank. The elevating mechanism includes a rectangular block and electric telescopic rods symmetrically installed in the rectangular grooves. Both ends of the rectangular block are respectively slidably arranged in the rectangular grooves on the same side. The telescopic ends of the electric telescopic rods on the same side are installed on the bottom surface of the same side end of the rectangular block. Connecting ports are evenly penetrated through the middle of the rectangular block.

[0008] As a preferred technical solution of the present utility model, the infrared sensor includes an infrared emitter installed in the middle of the left top surface of the rectangular block, an infrared receiver for use with the infrared emitter is installed in the middle of the right top surface of the rectangular block, a rectangular transparent block is installed at the receiving end of the infrared receiver, a rectangular cavity is opened in the middle of the rectangular transparent block, a rectangular floating block is slidably arranged in the rectangular cavity, air vents communicating with the rectangular cavity are opened on both the bottom surface and the top surface of the rectangular transparent block, and the infrared sensor is electrically connected to the electric telescopic rod.

[0009] As a preferred technical solution of the present utility model, the floating oil collection assembly includes a floating oil funnel installed at the connection port on the top surface of the rectangular block, a multi-section telescopic pipe is installed at the connection port on the bottom surface of the rectangular block, two limiting blocks are symmetrically installed in the middle of the floating oil funnel, an inverted frustum-shaped filter screen is installed in the middle of the floating oil funnel, and a butting port for use with the limiting blocks is opened on the inverted frustum-shaped filter screen.

[0010] As a preferred technical solution of the present utility model, oil discharge holes matching the positions of the connection ports are uniformly and vertically opened in the middle of the inner cavity bottom surface of the waste water tank, and the lower end of the multi-section telescopic pipe is installed with the oil discharge holes.

[0011] As a preferred technical solution of the present utility model, a plurality of oil discharge pipes are uniformly arranged on the bottom surface of the waste water tank, one end of the oil discharge pipe is installed with the oil discharge hole, and a switch valve is installed at the other end of the oil discharge pipe.

[0012] As a preferred technical solution of the present utility model, a floating oil collection box is installed on the front wall surface of the waste water tank, and the switch valve is located in the middle directly above the floating oil collection box.

[0013] As a preferred technical solution of the present utility model, the transmission height of the infrared rays of the infrared emitter and the infrared receiver is higher than the top surface height of the floating oil funnel.

[0014] The beneficial effects of the present utility model are:

[0015] 1. The industrial wastewater pretreatment device emits an infrared signal from an infrared emitter to an infrared receiver. When the infrared receiver can receive the infrared signal emitted by the infrared emitter, the electric telescopic rod continuously drives the rectangular block to descend. As the descent continues, the rectangular floating block in the rectangular transparent block contacts the wastewater liquid level. Then, as the rectangular block descends, the rectangular floating block continuously floats upward until the rectangular floating block blocks the receiving end of the infrared receiver, and the infrared receiver cannot receive the infrared signal emitted by the infrared emitter. Then, the electric telescopic rod stops descending. At this time, the top surface of the floating oil funnel is located between the wastewater and its upper floating oil layer, so that the floating oil flows into the floating oil funnel, enters the corresponding drain pipe through the multi-section telescopic pipe, and the floating oil can be discharged into the floating oil collection tank by opening the switch valve at the drain pipe. As the floating oil continuously flows into the floating oil funnel, the liquid level gradually drops, causing the rectangular floating block to slide downward and no longer block the receiving end of the infrared receiver. At this time, the infrared receiver receives the infrared signal emitted by the infrared emitter, and the electric telescopic rod continues to descend, so as to continuously collect the floating oil, and thus realize the adjustment of the oil removal height in real time according to the liquid level height.

[0016] 2. The industrial wastewater pretreatment device can appropriately install multiple floating oil collection components according to the requirements of the oil removal speed and the oil removal area to increase the treatment area, thereby improving the oil removal speed. Compared with the existing technology that uses an oil removal belt for oil removal, the oil removal rate and the oil removal area can be appropriately adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0024] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] Example: As Figures 1-5 shown, an industrial wastewater pretreatment device includes a wastewater tank 1. An lifting mechanism 3 is installed in the inner cavity of the wastewater tank 1. An infrared sensor 4 is installed on the lifting mechanism 3, and a floating oil collection component 5 is also installed on the lifting mechanism 3;

[0026] Rectangular grooves are symmetrically formed in the middle of the inner cavity side wall surface of the wastewater tank 1. The lifting mechanism 3 includes a rectangular block 301 and electric telescopic rods 303 symmetrically installed in the rectangular grooves. The two ends of the rectangular block 301 are respectively slidably arranged in the rectangular grooves on the same side. The telescopic ends of the electric telescopic rods 303 on the same side are installed on the bottom surface of the same side end of the rectangular block 301. Connection ports 302 are uniformly penetrated through the middle of the rectangular block 301.

[0027] Thereon, when there is wastewater to be treated in the wastewater tank 1 and the infrared sensor 4 is in a signal - receivable state, the electric telescopic rod 303 drives the rectangular block 301 to continuously descend until the infrared sensor 4 cannot receive the signal, and then the floating oil collection component 5 collects the floating oil on the surface of the wastewater.

[0028] As Figures 1-5As shown, in some embodiments, the infrared sensor 4 includes an infrared emitter 401 installed in the middle of the left top surface of the rectangular block 301. An infrared receiver 402 used in conjunction with the infrared emitter 401 is installed in the middle of the right top surface of the rectangular block 301. A rectangular transparent block 403 is installed at the receiving end of the infrared receiver 402. A rectangular cavity is formed in the middle of the rectangular transparent block 403. A rectangular floating block 404 is slidably arranged in the rectangular cavity. Vent holes communicating with the rectangular cavity are formed on both the bottom surface and the top surface of the rectangular transparent block 403. The infrared sensor 4 is electrically connected to the electric telescopic rod 303. The infrared emitter 401 emits an infrared signal to the infrared receiver 402. When the infrared receiver 402 can receive the infrared signal emitted by the infrared emitter 401, the electric telescopic rod 303 continuously drives the rectangular block 301 to descend. As the descent continues, the rectangular floating block 404 in the rectangular transparent block 403 contacts the wastewater liquid level. Then, as the rectangular block 301 descends, the rectangular floating block 404 continuously floats upward until the rectangular floating block 404 blocks the receiving end of the infrared receiver 402, and the infrared receiver 402 cannot receive the infrared signal emitted by the infrared emitter 401. Then, the electric telescopic rod 303 stops descending. At this time, the top surface of the floating oil funnel 501 is located between the wastewater and the floating oil on its upper layer. Then, the floating oil flows into the floating oil funnel 501. As the floating oil continuously flows into the floating oil funnel 501, the liquid level gradually descends, causing the rectangular floating block 404 to slide downward and no longer block the receiving end of the infrared receiver 402. At this time, the infrared receiver 402 receives the infrared signal emitted by the infrared emitter 401, and the electric telescopic rod 303 continues to descend. In this way, the floating oil is continuously collected.

[0029] As Figures 1-5 As shown, in some embodiments, the floating oil collection assembly 5 includes a floating oil funnel 501 installed on the connection port 302 on the top surface of the rectangular block 301. A multi-section telescopic pipe 504 is installed on the connection port 302 on the bottom surface of the rectangular block 301. Two limiting blocks 503 are symmetrically installed in the middle of the floating oil funnel 501. An inverted frustum-shaped filter screen 502 is installed in the middle of the floating oil funnel 501. A docking port matching the limiting block 503 is formed on the inverted frustum-shaped filter screen 502. The floating oil funnel 501 is used to collect the floating oil on the upper layer of the wastewater. The inverted frustum-shaped filter screen 502 is used to filter the solid waste in the floating oil to prevent the solid waste from entering the multi-section telescopic pipe 504 along with the floating oil. The limiting blocks 503 are used to limit the inverted frustum-shaped filter screen 502 to prevent it from detaching from the floating oil funnel 501. The multi-section telescopic pipe 504 is used to convey the floating oil. The multi-section setting is for coordinating with the up and down sliding of the rectangular block 301.

[0030] As Figures 1-5As shown, in some embodiments, oil discharge holes that are uniformly distributed and penetrate through the middle of the inner cavity bottom surface of the wastewater tank 1 are provided at positions that match the connection ports 302. The lower end of the multi-section telescopic pipe 504 is installed in the oil discharge holes. The floating oil is collected by the floating oil funnel 501 and then transported to the oil discharge pipe 505 through the multi-section telescopic pipe 504.

[0031] As Figures 1-5 shown, in some embodiments, a number of oil discharge pipes 505 are uniformly arranged on the bottom surface of the wastewater tank 1. One end of the oil discharge pipe 505 is installed in the oil discharge hole, and a switching valve 506 is installed at the other end of the oil discharge pipe 505. The floating oil in the multi-section telescopic pipe 504 is transported to the floating oil collection tank 2 through the oil discharge pipe 505. When the multi-section telescopic pipe 504 is not installed at the upper end of the oil discharge pipe 505, the oil discharge pipe 505 is closed by the switching valve 506 to prevent wastewater from entering the floating oil collection tank 2.

[0032] As Figures 1-5 shown, in some embodiments, a floating oil collection tank 2 is installed on the front wall surface of the wastewater tank 1. The switching valve 506 is located in the middle directly above the floating oil collection tank 2. The floating oil collection tank 2 is used for centralized collection of floating oil.

[0033] As Figures 1-5 shown, in some embodiments, the transmission height of the infrared rays of the infrared emitter 401 and the infrared receiver 402 is higher than the top surface height of the floating oil funnel 501. When the infrared receiver 402 can receive the infrared rays emitted by the infrared emitter 401, the electric telescopic rod 303 continuously contracts and descends, thereby driving the rectangular block 301 to continuously descend until the rectangular floating block 404 in the rectangular transparent block 403 on the infrared receiving end of the infrared receiver 402 floats up to block the infrared receiving end of the infrared receiver 402. Then the electric telescopic rod 303 stops descending. The floating oil funnel 501 collects the floating oil floating on the upper layer of the wastewater, and thus realizes real-time descent as the wastewater liquid level drops.

[0034] Working principle: When this industrial wastewater pretreatment device is in use, an infrared transmitter 401 emits an infrared signal to an infrared receiver 402. When the infrared receiver 402 can receive the infrared signal emitted by the infrared transmitter 401, the electric telescopic rod 303 continuously drives the rectangular block 301 to descend. As the descent continues, the rectangular floating block 404 in the rectangular transparent block 403 contacts the wastewater liquid level. Then, as the rectangular block 301 descends, the rectangular floating block 404 continuously floats upward until the rectangular floating block 404 blocks the receiving end of the infrared receiver 402, and the infrared receiver 402 cannot receive the infrared signal emitted by the infrared transmitter 401. Consequently, the electric telescopic rod 303 stops descending. At this time, the top surface of the floating oil funnel 501 is located between the wastewater and its upper layer of floating oil, enabling the floating oil to flow into the floating oil funnel 501 and enter the corresponding oil discharge pipe 505 through the multi-section telescopic pipe 504. By opening the on-off valve 506 at the oil discharge pipe 505, the floating oil can be discharged into the floating oil collection tank 2. As the floating oil continuously flows into the floating oil funnel 501, the liquid level gradually drops, causing the rectangular floating block 404 to slide downward and no longer block the receiving end of the infrared receiver 402. At this time, the infrared receiver 402 receives the infrared signal emitted by the infrared transmitter 401, and the electric telescopic rod 303 continues to descend, thus continuously collecting the floating oil.
