Description

Technical Field

[0001] The utility model provides a safety filtering device for hydrocarbon liquid, belonging to the technical field of filtering devices. Background Art

[0002] At present, hydrocarbon solutions are usually used to remove particulate matters such as grease and dust on the surface of workpieces in mechanical automation, and are widely used in industries such as hardware, jewelry, watches, automobiles, aerospace, electronics, electrical appliances, liquid crystals, and semiconductors. However, as the cleaning time prolongs, impurities in the hydrocarbon liquid will accumulate more and more. In order to be reused, a filtering device is usually required to filter the hydrocarbon liquid.

[0003] Existing filtering devices can basically meet the normal filtering needs of hydrocarbon liquid, but there are still certain defects: during filtering, since impurities will clog the screen, a dedicated vibration component driven by electric power resources is usually used to vibrate the screen to prevent impurities from clogging the screen. However, since the hydrocarbon liquid is a liquid medium, using electric power resources to drive a dedicated screen vibration component requires electric power on the one hand, resulting in a relatively high comprehensive cost, and on the other hand, there is also a potential safety hazard of electric leakage. Based on this, the utility model provides a safety filtering device for hydrocarbon liquid. Summary of the Utility Model

[0004] The technical problem solved by the utility model is that using a dedicated screen vibration component driven by electric power resources requires electric power on the one hand, resulting in a relatively high comprehensive cost, and on the other hand, there is also a potential safety hazard of electric leakage.

[0005] To solve the technical problem, the technical solution provided by the utility model is: a safety filtering device for hydrocarbon liquid, including a filter box. One side of the top of the filter box is provided with a liquid inlet, and a water wheel assembly is arranged in the liquid inlet. A plurality of impurity outlets are equidistantly arranged on one side wall of the filter box. The inner bottom wall of the impurity outlet is rotatably connected with a screen disposed in the filter box and inclined. A first support spring is fixedly connected between the upper inclined ends of the screen. A camshaft is arranged in the filter box at the top of the upper inclined end of the uppermost screen. A transmission assembly is arranged outside the filter box between the water wheel assembly and the camshaft. The water wheel assembly includes a water wheel shaft, and water wheel blades are arranged on the water wheel shaft in the liquid inlet.

[0006] Further, one end of the camshaft is rotatably connected to the inner side wall of the filter box, and the other end of the camshaft passes through the other side wall of the filter box. One end of the water wheel shaft is rotatably connected to the inner side wall of the liquid inlet, and the other end of the water wheel shaft passes through the other side wall of the liquid inlet.

[0007] Further, the transmission assembly includes a first belt pulley fixedly arranged at the other end of the camshaft and a second belt pulley fixedly arranged at the other end of the water wheel shaft, and a matching belt is arranged between the first belt pulley and the second belt pulley.

[0008] Further, a liquid outlet is provided at the bottom of the filter box, and support legs are symmetrically provided at the bottoms of the two side walls of the filter box.

[0009] Further, the mesh diameter of the upper sieve mesh is slightly larger than that of the lower sieve mesh, and the inclination angle of the sieve mesh is 15°-45°.

[0010] Further, a first connecting ear is provided on the inner bottom wall of the impurity outlet, a second connecting ear is provided at the bottom of the lower end of the sieve mesh obliquely, and the first connecting ear and the second connecting ear are rotatably connected by a rotating shaft.

[0011] Further, a second support spring is fixedly connected between the inner bottom wall of the filter box and the bottom of the upper end of the lowermost sieve mesh obliquely.

[0012] Advantages of the utility model:

[0013] When the hydrocarbon liquid impacts the top of the upper end of the uppermost sieve mesh obliquely, the impact force will press down the uppermost sieve mesh. Through the water wheel assembly, due to the impact of the hydrocarbon liquid flowing into the liquid inlet and its own gravity, the water wheel blades can be rotated, and then the water wheel shaft can be rotated. Through the action of the transmission assembly, the camshaft can be rotated. When the cam on the camshaft rotates, it can press down the uppermost sieve mesh, causing the upper end of the sieve mesh to move downward. Under the action of the first support spring and the second support spring, each sieve mesh can vibrate continuously, without using electric power resources to drive a special sieve mesh vibration component, saving electricity while reducing the comprehensive cost, greatly improving the use safety, and effectively preventing the occurrence of electric leakage.

[0019] The utility model will be further described below with reference to the drawings.

[0020] As shown in the appended Figure 1 、 3 、4: The present utility model provides a safety filtration device for hydrocarbon liquids, comprising a filter tank 1. On one side of the top of the filter tank 1, there is a liquid inlet 2. At the bottom of the filter tank 1, there is a liquid outlet 14. At the bottom of both side walls of the filter tank 1, there are symmetrically arranged support legs. On one side wall of the filter tank 1, there are a plurality of impurity outlets 4 arranged at equal intervals. Inside the bottom wall of the impurity outlet 4, there is a screen 5 rotatably connected, which is disposed inside the filter tank 1 and is inclined. The mesh diameter of the upper screen 5 is slightly larger than that of the lower screen 5. The inclination angle of the screen 5 is 15°-45°. The screen 5 at an appropriate angle can facilitate the sliding down of the impurities staying on it, and the sliding-down impurities are discharged from the impurity outlet 4. Between the upper ends of the inclined screen 5, there is a first support spring 6 fixedly connected. Between the bottom wall inside the filter tank 1 and the bottom of the upper end of the lowermost screen 5, there is a second support spring 16, which plays a supporting role. Inside the bottom wall of the impurity outlet 4, there is a first connecting ear. At the bottom of the lower end of the inclined screen 5, there is a second connecting ear. The first connecting ear and the second connecting ear are rotatably connected through a rotating shaft 15, ensuring that the lower end of the inclined screen 5 can rotate. The hydrocarbon liquid to be filtered is added into the filter tank 1 from the liquid inlet 2. Due to the impact force of the self-downward fall of the hydrocarbon liquid, when the hydrocarbon liquid impacts the top of the upper end of the uppermost screen 5, the impact force will press down the screen 5.

[0021] As shown in the appended Figure 2 、 3 : Inside the liquid inlet 2, there is a water wheel assembly 3. The water wheel assembly 3 includes a water wheel shaft 9. On the water wheel shaft 9, there are water wheel blades 10 disposed inside the liquid inlet 2. One end of the water wheel shaft 9 is rotatably connected to the inner side wall of the liquid inlet 2, and the other end of the water wheel shaft 9 passes through the other side wall of the liquid inlet 2. The hydrocarbon liquid is added into the filter tank 1 from the liquid inlet 2. Part of the hydrocarbon liquid accumulates between the water wheel blades 10. Due to the impact of the hydrocarbon liquid flowing into the liquid inlet 2 and its own gravity, the water wheel blades 10 can be rotated, and then the water wheel shaft 9 is rotated.

[0022] As shown in the appended Figure 1 、 3 : Inside the filter tank 1, there is a camshaft 7 disposed at the top of the upper end of the uppermost screen 5. One end of the camshaft 7 is rotatably connected to the inner side wall of the filter tank 1, and the other end of the camshaft 7 passes through the other side wall of the filter tank 1. Between the water wheel assembly 3 and the camshaft 7, there is a transmission assembly 8 disposed outside the filter tank 1. The transmission assembly 8 includes a first belt pulley 11 fixedly arranged at the other end of the camshaft 7 and a second belt pulley 12 fixedly arranged at the other end of the water wheel shaft 9. Between the first belt pulley 11 and the second belt pulley 12, there is a matching belt 13. The rotation of the water wheel shaft 9 drives the rotation of the second belt pulley 12. Under the action of the belt 13, the rotation of the second belt pulley 12 drives the rotation of the first belt pulley 11, and then drives the rotation of the camshaft 7. When the cam on the camshaft 7 rotates, it can press down the uppermost screen 5.

[0023] The principle of the present utility model

[0024] During use, the hydrocarbon liquid to be filtered is added into the filter box 1 from the liquid inlet 2. When the hydrocarbon liquid impacts the top of the upper end of the topmost screen 5, the impact force will press down the topmost screen 5. During the process of adding the hydrocarbon liquid from the liquid inlet 2 into the filter box 1, through the water wheel assembly 3, due to the impact of the hydrocarbon liquid flowing into the liquid inlet 2 and its own gravity, the water wheel blades 10 can be rotated, and then the water wheel shaft 9 can be rotated. Through the action of the transmission assembly 8, the camshaft 7 can be rotated. When the cam on the camshaft 7 rotates, it can press down the topmost screen 5, causing the upper end of the screen 5 to move downward. Under the action of the first support spring 6 and the second support spring 16, the first support spring 6 and the second support spring 16 are compressed and then rebound, so that each screen 5 can vibrate continuously. There is no need to use electric power resources to drive a special screen vibration component, which saves electricity and reduces the comprehensive cost, greatly improves the use safety, and effectively prevents the occurrence of electric leakage.

[0025] The hydrocarbon liquid flowing into the filter box 1 is filtered successively through multiple screens 5 from top to bottom. The impurities remaining on the top of the screen 5 are discharged from the impurity outlet 4, and the filtered hydrocarbon liquid is discharged from the liquid outlet 14. Multiple filtrations can effectively improve the filtration accuracy, and the quality of the finally obtained filtered hydrocarbon liquid is greatly improved.

[0026] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.
