Description

Technical Field

[0001] This utility model relates to the field of oil filter technology, specifically an adsorption type oil filter. Background Technology

[0002] The magnetic grid oil filter is a new type of oil filtration equipment. It uses neodymium iron boron strong magnetic rods distributed in a ring in the filter cartridge to adsorb metal particles in the oil and entrain some non-metal particles. The magnetic grid oil filter uses magnetic adsorption to adsorb contaminants in the oil without increasing the resistance of the oil flow in the oil tank. This purification process consumes no energy and can handle high viscosity oils above 100 cst with high filtration efficiency.

[0003] The existing magnetic grid adsorption oil filter has the following drawbacks during use: it generally works by inserting strong magnetic rods into the oil to adsorb metal particles in the oil. However, the magnetic rods are spaced far apart, making it difficult for all the metal particles in the oil to be adsorbed onto them, resulting in poor filtration. In addition, the existing magnetic grid adsorption oil filter requires the oil to be cooled before filtration can be performed. Otherwise, the high temperature of the oil will cause the magnetic rods to lose their magnetism, affecting the adsorption effect. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: an adsorption-type oil filter, comprising: a main body and a cooling mechanism. The main body includes a cylinder, a guide installed on the inner wall of the cylinder, a plurality of magnetic rods fixed on the top wall of the cylinder and extending into the guide, a pretreatment shell fixed on one side of the cylinder, a coarse filter screen fixed on the inner wall of the pretreatment shell, an oil inlet pipe installed on one side of the pretreatment shell and communicating with the inner cavity of the pretreatment shell, a first connecting pipe connecting the top of the pretreatment shell and the inner cavity of the cylinder, a second shell installed on the other side of the cylinder, and an adsorption medium layer disposed in the inner cavity of the second shell.

[0006] The guide includes partitions symmetrically fixed on the inner wall of the cylinder and multiple sleeves arranged in a ring array and connected to the partitions. The magnetic rod extends into the inner cavity of the sleeve, and there is a gap between the magnetic rod and the inner wall of the sleeve.

[0007] The cooling mechanism includes a heat exchanger installed on the inner wall of the pretreatment shell, an inlet pipe installed on one side of the pretreatment shell and extending into the pretreatment shell, and an outlet pipe installed on the pretreatment shell and communicating with the inner cavity of the pretreatment shell.

[0011] In a preferred embodiment, the present invention can be further configured such that: a second connecting pipe is provided at the top of the second housing and communicates with the top of the inner cavity of the cylinder, and an oil outlet pipe is installed at the bottom of the second housing.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, a cylindrical body is provided, and a guide component is provided in the inner cavity of the cylindrical body. The guide component consists of two opposing partitions and multiple sleeves arranged in a ring array and connecting the two sides of the opposing partitions. Multiple magnetic rods are installed in a ring array on the inner top wall of the cylindrical body and extend into the inner cavity of the sleeves. There is a gap between the magnetic rods and the sleeves. Through the above arrangement, when the oil is sent into the cylindrical body, it can enter the inner cavity of the sleeves and flow along the gap between the magnetic rods and the inner wall of the sleeves.

[0014] 2. In this utility model, a pretreatment shell is provided on one side of the cylinder. The pretreatment shell is connected to the inner cavity of the cylinder through a first connecting pipe.

An adsorption medium layer is filled in the inner cavity of the second shell. After the oil enters the inner cavity of the second shell, the adsorption medium layer can adsorb and remove the deterioration products in the oil, thereby playing a role in deacidification and decolorization, and can efficiently filter the oil.

[0015] 3. In this utility model, a heat exchanger is installed on the inner wall of the pretreatment shell.

This effectively avoids the phenomenon of high-temperature oil affecting the magnetic force of the magnetic rod, further increasing the practical performance. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figure 1-4 As shown, this embodiment provides an adsorption-type oil filter, including: a main body 100 and a cooling mechanism 200.

[0027] The main structure 100 includes a cylinder 110, a guide 120 installed on the inner wall of the cylinder 110, a plurality of magnetic rods 130 fixed on the inner top wall of the cylinder 110 and extending into the guide 120, a pretreatment housing 140 fixed on one side of the cylinder 110, a coarse filter screen 150 fixed on the inner wall of the pretreatment housing 140, an oil inlet pipe 160 installed on one side of the pretreatment housing 140 and communicating with the inner cavity of the pretreatment housing 140, a first connecting pipe 170 connecting the top of the pretreatment housing 140 and the inner cavity of the cylinder 110, a second housing 180 installed on the other side of the cylinder 110, and an adsorption medium layer 190 disposed in the inner cavity of the second housing 180.

[0028] The cylinder 110 is used to install other components. The guide 120 includes partitions 121 symmetrically fixed on the inner wall of the cylinder 110 and multiple sleeves 122 arranged in a ring array and connected to the partitions 121. Meanwhile, the magnetic rods 130 are arranged in a ring array with their bottom ends extending into the inner cavity of the sleeves 122. There is a gap between the magnetic rods 130 and the inner wall of the sleeves 122. With this arrangement, after the oil is sent into the cylinder 110, it can enter the inner cavity of the sleeves 122 and flow along the gap between the magnetic rods 130 and the inner wall of the sleeves 122. This allows the magnetic rods 130 to completely adsorb the metal particles in the oil, avoiding the situation where the gap between adjacent magnetic rods 130 is too large, resulting in metal particles remaining in the oil.

[0029] In addition, a first drain pipe 111 is provided at the bottom of the cylinder 110, and a first electric valve 112 is installed on the first drain pipe 111. The magnetic rod 130 is an electromagnetic rod 130. When there are a lot of metal particles on the magnetic rod 130, the power supply to the magnetic rod 130 is turned off. At this time, the magnetic rod 130 loses its magnetic force, and the debris falls into the bottom of the cylinder 110 under the action of gravity. At this time, the first electric valve 112 is opened, so that the metal debris is discharged through the first drain pipe 111.

[0030] The pretreatment housing 140 is used to install the coarse filter screen 150 and the cooling mechanism 200 for pretreatment of the oil. The coarse filter screen 150 is used to filter larger metal particles in the oil. A second drain pipe 141 is provided at the bottom of the pretreatment housing 140. A second electric valve 142 is installed on the second drain pipe 141. When there are a lot of metal debris accumulated below the coarse filter screen 150, the second electric valve 142 is opened, and the metal debris is discharged through the second drain pipe 141.

[0031] One end of the first connecting pipe 170 is connected to the top of the pretreatment housing 140, and the other end is connected to the inner cavity of the cylinder 110, for sending the oil filtered by the coarse filter screen 150 into the cylinder 110.

[0032] The second housing 180 is used to install the adsorption medium layer 190. A second connecting pipe 181 is provided at the top of the second housing 180 to communicate with the top of the inner cavity of the cylinder 110, so as to facilitate the oil in the cylinder 110 to enter the inner cavity of the second housing 180. An oil outlet pipe 182 is installed at the bottom of the second housing 180 for sending out the treated oil. The adsorption medium layer 190 is used to adsorb and remove the deteriorated products in the oil, playing a role in deacidification and decolorization, for example:

[0033] Nano silica adsorbents, by adding nano silica particles to hydraulic oil, can effectively adsorb impurities and tiny particles suspended in the hydraulic oil, thus filtering and cleaning the hydraulic oil.

[0034] Acidic adsorbents are used because hydraulic oil often contains small amounts of acidic substances, which can easily cause corrosion and oxidation of metal parts. These harmful substances can be adsorbed to protect the normal operation of the hydraulic system.

[0035] Activated carbon adsorbent: Activated carbon is a natural organic material with strong adsorption capacity. It can effectively adsorb and remove impurities such as ozone, free acid, and water from hydraulic oil, ensuring the stability and safety of the hydraulic system.

[0036] The cooling mechanism 200 is used to reduce the temperature of the oil and prevent the high-temperature oil from affecting the magnetism of the magnetic rod 130. It includes a heat exchanger 210 installed on the inner wall of the pretreatment housing 140, a water inlet pipe 220 installed on one side of the pretreatment housing 140 and extending into the pretreatment housing 140, and a water outlet pipe 230 installed on the pretreatment housing 140 and communicating with the inner cavity of the pretreatment housing 140.

[0037] The heat exchanger 210 includes side plates 211 symmetrically fixed on the inner wall of the pretreatment shell 140 and multiple heat exchange tubes 212 communicating with the opposite side plates 211. A cavity is formed between the opposite side plates 211 and the inner wall of the pretreatment shell 140. The water inlet pipe 220 and the water outlet pipe 230 are connected to the cavity. The heat exchange tubes 212 are made of thermally conductive material. When the high-temperature oil is filtered through the coarse filter screen 150, it enters the heat exchange tubes 212. At this time, the cooling water enters the cavity through the water inlet pipe 220 and exchanges heat with the oil through the heat exchange tubes 212 to cool the oil and reduce its temperature. The cooling water that has absorbed heat is discharged through the water outlet pipe 230.

[0038] The working principle and usage process of this utility model are as follows: During use, high-temperature oil is fed into the pretreatment shell 140 through the oil inlet pipe 160. After passing through the coarse filter screen 150, larger metal particles in the oil are filtered out. The filtered oil then enters the heat exchange tube 212. Cooling water enters the cavity through the water inlet pipe 220 and exchanges heat with the oil through the heat exchange tube 212, cooling the oil. The cooled water, having absorbed heat, is discharged through the water outlet pipe 230. The cooled oil is then fed into the cylinder through the first connecting pipe 170. As oil is continuously fed into the inner cavity of the cylinder 110, the oil level in the inner cavity of the cylinder 110 rises and enters the sleeve 122. The oil enters the gap between the sleeve 122 and the magnetic rod 130. At this time, the metal particles in the oil are adsorbed by the magnetic rod 130. Then, the oil enters the inner cavity of the second housing 180 through the second connecting pipe 181. The adsorption medium layer 190 can adsorb and remove the deterioration products in the oil, playing the role of deacidification and decolorization. After completion, the oil is discharged through the oil outlet pipe 182, completing the filtration process.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
