Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a floating oil collecting device used in an oily wastewater pool. Background Art

[0002] In daily life wastewater pools, especially wastewater discharged from catering enterprises and hotels contains a large amount of waste oil from animals and plants. Since the density of waste oil is less than that of water, these waste oils float on the surface of the wastewater pool. If these wastewaters are directly separated by oil-water separation, a large amount of wastewater needs to be processed, and the workload of the oil-water separator is large. Therefore, for oily wastewater pools, the existing method is to manually collect the surface waste oil in the wastewater pool. This collection method is not only inefficient, but also incompletely collects the waste oil in the wastewater pool. Therefore, it is necessary to design a floating oil collection device suitable for use in oily wastewater pools to solve the problem of waste oil collection. Utility Model Content

[0003] The utility model aims to provide a floating oil collection device, aiming to solve the problem of collecting floating oil in an oily wastewater pool.

[0004] In view of this, the technical solution provided by the utility model is: a floating oil collection device, including a floating plate, a floating oil collection head and a floating rod mechanism, an extraction pump is installed on the upper part of the floating plate, a plurality of supports are provided at the bottom of the floating plate, a floating ball is connected to the bottom of the support, the floating rod mechanism includes a pair of floating rods, the upper part of the floating rod is a sliding rod, the lower part of the floating rod is a float arranged inside the hollow, the pair of floating rods are connected together by a clamp, the sliding rod is slidably connected to the floating plate, the floating oil collection head includes a collecting pipe column with an opening, the collecting pipe column can be adjustably clamped on the clamp, by means of the floating rod mechanism, the opening of the collecting pipe column of the floating oil collection head automatically sinks below the surface of the waste oil in the wastewater pool, the bottom of the collecting pipe column is provided with a round head bottom, the round head bottom is provided with a collecting outlet, and the collecting outlet is connected to the extraction pump through a telescopic pipe pipeline.

[0005] Further, the clamp includes a first clamp ring located in the middle, a pair of second clamp rings for fixing and clamping with the float are provided on both sides of the first clamp ring, an internal thread is provided in the first clamp ring, an external thread corresponding to the first clamp ring is provided on the outer wall of the collection column, and the collection column and the first clamp ring are adjustable and fixed by threads. After the floating oil collection head is connected to the floating rod mechanism, the floating rod mechanism can drive the floating oil collection head to suspend at a specific position in the liquid, and since the floating rod mechanism can automatically adjust according to the height of the liquid level in the wastewater pool, the self-adjustment of the suspension position of the floating oil collection head is realized accordingly, and the opening of the collection column is adjusted to a reasonable position below the surface of the waste oil in the wastewater pool by the adjustable fixation of the first clamp ring to the collection column, so that the collection column can collect waste oil without sucking in too much wastewater, and reduce the oil-water separation process of the waste liquid after the waste oil is collected.

[0006] Furthermore, the floating plate is provided with a through hole in the direction facing the floating oil collecting head. When the floating oil collecting head is pumping waste oil, the opening of the collecting pipe column will generate an adsorption vortex, and a partial vacuum will be generated at the opening of the collecting pipe column. Therefore, the through hole can provide air circulation, reduce the vacuum at the opening of the collecting pipe column, and thus prevent the floating oil collecting head from being adsorbed and attached to the bottom of the floating plate due to the vacuum.

[0007] Furthermore, the floating oil collecting head has a clamping ring between the collecting pipe column and the bottom of the round head for limiting the position of the clamping ring. Therefore, in the process of the collecting pipe column thread clamping the clamping ring, the clamping ring is limited to prevent the clamping ring from excessively sliding out of the collecting pipe column.

[0008] Furthermore, a linear bearing is installed on the floating plate, and the slide rod is sleeved in the linear bearing, and a sliding connection is formed between the slide rod and the floating plate through the linear bearing. The floating rod is connected by the sliding connection of the linear bearing, so that the floating rod floats vertically and stably on the wastewater pool, thereby ensuring that the end face of the collection column and the liquid surface in the wastewater pool remain parallel, thereby ensuring that the collection column can absorb and collect the floating oil on the liquid surface.

[0009] The utility model uses a plurality of floating balls connected to a support to enable the floating plate to float on the liquid surface of the wastewater pool in a balanced manner. The floating oil collecting head is adjusted according to the position of the clamp clamped on the collecting pipe column to realize that the opening of the collecting pipe column of the floating oil collecting head automatically sinks below the surface of the waste oil in the wastewater pool, and then the waste oil on the surface of the wastewater pool is extracted and collected by an extraction pump, thereby solving the problem of waste oil collection in the wastewater pool and greatly improving the collection efficiency of the waste oil in the wastewater pool. Moreover, by adjusting the reasonable position of the floating oil collecting head below the liquid surface of the wastewater pool, the waste oil in the wastewater pool can be collected more thoroughly.

DETAILED DESCRIPTION

[0017] The following is a brief description of the implementation of the present utility model in conjunction with the accompanying drawings.

[0018] This utility model, refer to 1- Figure 3 A floating oil collection device includes a floating plate 21, a floating oil collection head 23 and a floating rod mechanism 24. An extraction pump 25 is installed on the upper part of the floating plate 21, and a plurality of supports 211 are provided at the bottom of the floating plate 21. A floating ball 22 is connected to the bottom of the support 211. In this embodiment, in order to ensure that the floating plate 21 can be suspended in a balanced manner on the liquid surface of the wastewater pool 10, the supports 211 are evenly arranged at the four corners of the floating plate 21, so that the floating ball 22 can better suspend the floating plate 21 in a balanced manner.

[0019] Reference Figure 5The float rod mechanism 24 includes a pair of float rods 241, the upper part of the float rod 241 is a slide rod 241a, the lower part of the float rod 241 is a float 241b with a hollow interior, the pair of float rods 241 are connected together by a clamp 242, the clamp 242 includes a first clamp ring 242a located in the middle, the first clamp ring 242a is provided with an internal thread, and both sides of the first clamp ring 242a are provided with a pair of second clamp rings 242b for fixedly clamping with the float 241b, the pair of second clamp rings 242b connect the pair of float rods 241 into one, and the slide rod 241a is slidably connected to the floating plate 21.

[0020] Reference Figure 4 The floating oil collecting head 23 comprises a collecting column 231 with an opening, a round bottom 232 is provided at the bottom of the collecting column 231, a collecting outlet 234 is provided at the round bottom 232, and the collecting outlet 234 is connected to the extraction pump 25 through a telescopic pipe 26 pipeline, and the telescopic pipe 26 can realize a flexible connection between the collecting outlet 234 and the extraction pump 25 according to the floating telescopic length of the floating rod mechanism 24, wherein the collecting column 231 can be adjustably clamped on the clamp 242, and the outer wall of the collecting column 231 is provided with an external thread corresponding to the first clamp ring 242a of the clamp 242, and the collecting column 231 and the first clamp ring 242a are adjusted by threads to realize an adjustable fixation. After the floating oil collecting head 23 is connected to the float rod mechanism 24, the float rod mechanism 24 can drive the floating oil collecting head 23 to suspend at a specific position in the liquid. Moreover, since the float rod mechanism 24 can automatically adjust according to the height of the liquid level in the wastewater tank 10, the self-adjustment of the suspension position of the floating oil collecting head 23 is correspondingly achieved. The first clamp ring 242a is used to adjust the collection column 231. The opening of the collection column 231 is adjusted to a reasonable position that is always below the surface of the waste oil in the wastewater tank 10, so that the collection column 231 does not inhale too much wastewater during the waste oil collection process, thereby reducing the oil-water separation of the waste liquid after the waste oil is collected.

[0021] In the present invention, in order to prevent the clamp 242 from excessively spirally sliding out of the collecting pipe column 231 , the floating oil collecting head 23 has a clamp ring 233 between the collecting pipe column 231 and the round head bottom 232 for limiting the clamp 242 .

[0022] In the utility model, a linear bearing 28 is installed on the floating plate 21, and the sliding rod 241a is sleeved in the linear bearing 28. Through the linear bearing 28, a sliding connection is formed between the sliding rod 241a and the floating plate 21. The floating rod 241 is slidably connected through the linear bearing 28, so that the floating rod 241 floats vertically and stably on the wastewater tank 10, thereby ensuring that the end face of the collecting pipe column 231 and the liquid surface in the wastewater tank 10 remain parallel, thereby ensuring that the collecting pipe column 231 can absorb and collect the floating oil on the liquid surface.

[0023] In the utility model, the floating plate 21 is provided with a through hole 212 in the direction opposite to the floating oil collecting head 23. When the extraction pump 25 extracts waste oil from the floating oil collecting head 23, the opening of the collecting column 231 will generate an adsorption vortex, and a partial vacuum will be generated at the opening of the collecting column 231. Therefore, the through hole 212 can provide air circulation, reduce the vacuum at the opening of the collecting column 231, and thus prevent the floating oil collecting head 23 from being adsorbed and attached to the bottom of the floating plate 21 due to the vacuum.

[0024] This utility model, when implemented specifically, refers to Figure 6 The floating oil collection device 20 is used in the wastewater pool 10 containing oil. The floating oil collection device 20 can be installed with an automatic sliding device using the existing technology, so that the floating oil collection device 20 can collect oil at different positions in the wastewater pool 10 under the traction of the automatic sliding device. After the floating oil collection device 20 is placed in the wastewater pool 10, the floating oil collection device 20 is suspended on the liquid surface of the wastewater pool 10 due to the provision of a float 22. The floating oil collection head 23 is adjusted according to the position of the clamp 242 clamped on the collection column 231 to realize the floating oil collection head. The opening of the collecting pipe column 231 of 23 automatically sinks below the surface of the waste oil in the wastewater tank 10, and then the waste oil on the surface of the wastewater tank 10 is extracted by the extraction pump 25. The extraction pump 25 of the floating oil collection device 20 is connected to a water outlet pipe 27, and the water outlet pipe 27 is connected to an extendable hose 30. The hose 30 realizes a flexible connection between the water outlet pipe 27 and a waste oil collection box 40 at the edge of the wastewater tank 10, and the waste oil collection box 40 is used for collection to obtain an enriched oil-containing oil-wastewater mixed liquid, which is then convenient for further separation of oil and water in an oil-water separator.

[0025] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
