Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling production of aluminum alloy metals, and particularly relates to an online emulsion skimmer. Background Technique

[0002] In the hot rolling process of aluminum processing, the emulsion plays a role in reducing roll wear, preventing adhesion between metals, improving the surface quality of products, and cooling the equipment. During the cooling and lubrication of products by the emulsion, it will carry away aluminum ash, mineral oil or impurities generated during rolling. If the emulsion is to be reused, this part of floating oil and impurities needs to be removed by static settlement.

[0003] The existing emulsion skimmers cannot achieve online skimming. Usually, manual skimming or regular discharge of contaminated emulsion is relied on to control the emulsion pollution degree. However, the above methods have poor skimming quality, unstable quantity, frequent index fluctuations, seriously affecting the surface quality of the strip and the stability of production efficiency; at the same time, regular discharge of contaminated emulsion results in waste of emulsion. Content of the Utility Model

[0004] The purpose of the utility model is to provide an online emulsion skimmer. By setting a plurality of skimming chambers, each skimming chamber is an overflow chamber, thus extending the flow path of the emulsion, achieving the effect of online skimming, greatly improving the oil removal efficiency and oil removal effect, and avoiding waste of emulsion.

[0005] To achieve the above purpose, the utility model provides an online emulsion skimmer, which includes a support frame and an oil storage chamber fixedly installed on the support frame. An emulsion inlet and an emulsion outlet are respectively arranged at both ends of the oil storage chamber; the interior of the oil storage chamber is divided into a plurality of skimming chambers by a partition from the emulsion inlet to the emulsion outlet; each skimming chamber is divided into a filtering chamber and an overflow chamber that communicate with each other through the bottom by a baffle; a dirty oil discharge port is arranged on the top side wall of the filtering chamber; the overflow chamber communicates with the top of the filtering chamber of the adjacent skimming chamber through an overflow port; the height of the overflow port is lower than the height of the dirty oil discharge port; an impurity discharge port is arranged at the bottom of the skimming chamber; a vent port is also arranged in the middle and lower part of the skimming chamber.

[0006] After adopting the above structure, by setting a plurality of skimming chambers, a rotary liquid flow channel is formed in each skimming chamber, thus extending the flow path of the emulsion, enabling the dirty oil in the emulsion to have enough time to float up, and the floating dirty oil overflows and discharges through the dirty oil discharge port, thus realizing the function of online skimming, greatly improving the skimming efficiency, ensuring the quality of the emulsion at the same time, and avoiding waste of emulsion caused by regular discharge of contaminated emulsion.

[0007] In order to reduce the liquid inlet speed and achieve uniform liquid inlet at the same time, a liquid inlet head is installed at the position of the emulsion inlet. The liquid inlet head includes a liquid inlet section and a flared section. The liquid inlet section is of a cylindrical structure; the flared section is of a flat structure.

[0008] To prevent large impurities from entering the oil skimming chamber, a sieve basket is installed at the position of the emulsion inlet in the oil storage chamber, and the sieve basket is detachably installed at the emulsion inlet position.

[0009] To facilitate the collection and discharge of waste oil, a sewage discharge cavity is provided on the side wall of the oil storage chamber adjacent to the waste oil discharge port. All waste oil discharge ports are connected to the sewage discharge cavity. The bottom of the sewage discharge cavity is a conical bottom, and a sewage collection port is provided at its lowest position.

[0010] To facilitate the discharge of the emulsion, a liquid discharge cavity is provided on the side wall of the rear end of the oil storage chamber adjacent to the emulsion outlet. The bottom of the liquid discharge cavity is a conical bottom, and a liquid discharge port is provided at its lowest position.

[0011] To facilitate the collection of impurities, the bottom of the oil skimming chamber is a conical bottom, and the impurity discharge port is located at its lowest position. The impurity discharge ports of all oil skimming chambers are connected in parallel to the sewage discharge pipe through pipes.

[0012] To accelerate the discharge speed of waste oil and reduce the waste of emulsion, an air purge port is provided on the side wall of the oil skimming chamber opposite to the waste oil discharge port.

[0013] To improve the stable rise of waste oil after collection and avoid interference caused by air purging, several oil baffle plates are arranged in parallel at the top of the oil storage chamber. The top height of the oil baffle plates is lower than the height of the waste oil discharge port; the oil baffle plates are inclined from the direction of the air purge port towards the waste oil discharge port.

[0014] To create resistance to the descent of the emulsion, reduce the descent speed of the emulsion, and at the same time increase the probability of collision of waste oil, so that the waste oil aggregates into large particle oil stains for easy rapid rise, a baffle net is arranged in the filtration chamber, and the baffle net is inclined in the filtration chamber.

[0015] After adopting the above technical solution, the beneficial effects of the present utility model are:

[0016] An online emulsion oil skimmer of the present utility model solves the technical problems in the prior art that emulsion needs to be skimmed manually, with low efficiency and poor effect; regularly discharging the emulsion to reduce the pollution concentration causes waste of the emulsion. The present utility model realizes the effect of online oil skimming by setting a plurality of oil skimming chambers, each oil skimming chamber being an overflow chamber, thus prolonging the flow path of the emulsion, greatly improving the oil removal efficiency and oil removal effect, and avoiding waste of the emulsion.

Specific embodiments

[0021] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0022] All orientations referred to in this specification are based on the orientation when an on-line emulsion skimmer of the present utility model is operating normally, without limiting its orientation during storage and transportation, only representing relative positional relationships and not absolute positional relationships.

[0023] As Figure 1 、 Figure 2 and Figure 3 collectively shown, an on-line emulsion skimmer includes a support frame and an oil storage chamber 1 fixedly installed on the support frame. The support frame is welded by square tubes and is used to support the oil storage chamber 1. An emulsion inlet 11 and an emulsion outlet 12 are respectively arranged at both ends of the oil storage chamber 1; the emulsion to be filtered enters the oil storage chamber 1 from the emulsion inlet 11, and the filtered emulsion is discharged from the emulsion outlet 12 out of the oil storage chamber 1.

[0024] In order to reduce the flow rate of the emulsion when it enters the oil storage chamber 1 and avoid causing a large disturbance to the liquid in the oil storage chamber 1, which is not conducive to stratification, a liquid inlet head 4 is installed at the position of the emulsion inlet 11. The liquid inlet head 4 includes a liquid inlet section 41 and a flared section 42. The liquid inlet section 41 is a cylindrical structure and is connected to the liquid inlet pipe. The flared section 42 connects the liquid inlet section 41 and the emulsion inlet 11, is in a flat structure and its liquid inlet width gradually increases. By gradually increasing the liquid inlet width, the liquid inlet speed is reduced, and the liquid inlet is evenly distributed in the width direction of the oil storage chamber 1, thereby reducing the liquid inlet impact force.

[0025] Furthermore, in order to avoid large impurities in the incoming liquid, a sieve basket 111 is installed at the position of the emulsion inlet 11 inside the oil storage chamber 1. The sieve basket 111 is detachably installed at the position of the emulsion inlet 11. After the emulsion to be filtered enters from the emulsion inlet 11, it needs to pass through the sieve basket 111 for preliminary filtration, so as to avoid large impurities from entering the oil storage chamber 1.

[0026] The oil storage chamber 1 is partitioned into a plurality of oil skimming chambers 31 by a partition plate 3 between the emulsion inlet 11 and the emulsion outlet 12; in this embodiment, four partition plates 3 are provided, and the space in the oil storage chamber 1 is partitioned into five oil skimming chambers 31 by the four partition plates 3. Each oil skimming chamber 31 is partitioned into a filtering chamber 311 and an overflow chamber 312 that communicate through the bottom by a baffle 32; a dirty oil discharge port 33 is provided on the top side wall of the filtering chamber 311, and the stratified dirty oil overflows from the dirty oil discharge port 33. The overflow chamber 312 communicates with the top of the filtering chamber 311 of the adjacent oil skimming chamber 31 through an overflow port 34; the height of the overflow port 34 is lower than the height of the dirty oil discharge port 33; the emulsion overflows and flows between the respective oil skimming chambers 31 from the overflow port 34, and the height of the overflow port 34 is lower than the height of the dirty oil discharge port 33, thus ensuring that the liquid level height is higher than the height of the overflow port 34, realizing the overflow of the emulsion while ensuring that the dirty oil overflows from the dirty oil discharge port 33.

[0027] In order to facilitate the collection of the dirty oil in the dirty oil discharge port 33, a sewage discharge chamber 38 is provided on the side of the oil storage chamber 1, on the side wall adjacent to the dirty oil discharge port 33, and all the dirty oil discharge ports 33 communicate with the sewage discharge chamber 38. The dirty oil directly overflows from the dirty oil discharge port 33 into the sewage discharge chamber 38 for collection. In order to facilitate the discharge of the dirty oil, the bottom of the sewage discharge chamber 38 is a conical bottom, and a sewage collection port 381 is provided at its lowest position. The sewage collection port 381 is connected to the outside through a pipeline to discharge the dirty oil in real time.

[0028] In order to facilitate the collection of the filtered emulsion, a liquid discharge chamber 39 is provided at the rear end of the oil storage chamber 1, on the side wall adjacent to the emulsion outlet 12, and the filtered emulsion overflows from the emulsion outlet 12 into the liquid discharge chamber 39 for collection. The bottom of the liquid discharge chamber 39 is a conical bottom, and a liquid discharge port 391 is provided at its lowest position. The liquid discharge port 391 is connected to the outside through a pipeline to convey the filtered emulsion away in real time.

[0029] The bottom of the oil skimming chamber 31 is a conical bottom, which is convenient for the accumulation of impurities. An impurity discharge port 35 is provided at the lowest position of the conical bottom, and all the impurity discharge ports 35 are connected in parallel to a sewage discharge pipe 351 through pipelines, and the impurity discharge ports 35 regularly clean away the settled impurities.

[0030] An emptying port 36 is further provided in the middle and lower part of the oil skimming chamber 31, and all the emptying ports 36 are connected in parallel to an oil discharge pipe 361 through pipelines. When it is necessary to empty the oil skimming chamber 31, the emulsion inside is emptied through the emptying port 36.

[0031] The emulsion to be filtered enters the filtration chamber 311 of the leftmost skimming chamber 31 from the emulsion inlet 11, and then undergoes primary stratification in the filtration chamber 311. The heavier impurities settle to the bottom of the filtration chamber 311, while the emulsion collects in the middle of the filtration chamber 311, and the lighter dirty oil floats to the top; The emulsion after primary stratification enters the filtration chamber 311 of the second skimming chamber 31 from the overflow chamber 312 through the overflow port 34, and then undergoes secondary stratification, and so on, until after five - stage stratification, it is discharged from the emulsion outlet 12 to the oil storage chamber 1; The dirty oil floating on the top of the skimming chamber 31 overflows and is discharged from the dirty oil discharge port 33 from the oil storage chamber 1; The impurities deposited at the bottom of the skimming chamber 31 are discharged from the impurity discharge port 35. When the oil storage chamber 1 needs to be cleaned, the emulsion in the oil storage chamber 1 is discharged from the vent port 36. The emulsion undergoes multi - stage stratification during the flow process, thereby achieving on - line skimming.

[0032] There is more dirty oil in the previous stages of stratification, that is, there is more dirty oil on the top of the previous skimming chamber 31, and less dirty oil on the top of the subsequent skimming chamber 31. Due to the principle of communicating vessels, the liquid level of the previous skimming chamber 31 will be higher than that of the subsequent skimming chamber 31, so that too much emulsion will not be mis - discharged from the skimming chamber 31.

[0033] In order to accelerate the movement speed of the dirty oil on the top of the skimming chamber 31, an air purge port 37 is provided on the side wall of the skimming chamber 31 opposite to the dirty oil discharge port 33. The air purge port 37 is connected to an air pipe, and air is blown into the air purge port 37 through the air pipe. The air blows onto the liquid surface of the emulsion, accelerating the flow of the surface dirty oil towards the dirty oil discharge port 33 side, thereby increasing the discharge speed of the dirty oil and reducing the waste of the emulsion.

[0034] In order to reduce the flow resistance of the emulsion and increase the probability of its collision and collection, several oil baffle plates 51 are arranged in parallel at the top of the oil storage chamber 1. The top height of the oil baffle plates 51 is lower than the height of the dirty oil discharge port 33; The oil baffle plates 51 are inclined from the direction of the air purge port 37 towards the dirty oil discharge port 33. This inclination method is more conducive to the dirty oil floating onto the liquid surface through the oil baffle plates 51, avoiding the interference of the wind on the rising dirty oil and increasing the floating resistance of the dirty oil. A retaining net 52 is arranged in the filtration chamber 311. The retaining net 52 is inclined in the filtration chamber 311, so as to reduce the speed of the emulsion during the descent process of the emulsion. At the same time, the emulsion is shunted, increasing the collision probability of the dirty oil in the emulsion, enabling the dirty oil to collect and thus float.

[0035] The utility model relates to an online emulsion skimmer, which solves the technical problems in the prior art that the emulsion needs to be skimmed manually, resulting in low efficiency and poor effect; and the emulsion is discharged regularly to reduce the pollution concentration, causing waste of the emulsion. The utility model realizes the online skimming effect by arranging a plurality of skimming chambers, each skimming chamber being an overflow chamber, thereby prolonging the flow path of the emulsion, greatly improving the oil removal efficiency and effect, and avoiding waste of the emulsion.

[0036] Certainly, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the utility model should also fall within the protection scope of the utility model.
