Description

Technical Field

[0001] The invention relates to technologies related to grease barrels, and more specifically to a bottom oil suction cleaning device for lubricating grease barrels. Background Art

[0002] As a general-purpose container, oil drums have the advantages of being easy to transport and count. However, for lubricating greases with a certain degree of adhesion, various methods for effectively absorbing the bottom oil in the drum have certain shortcomings and uncertainties.

[0003] The existing operation modes are as follows:

[0004] 1) The traditional method of using tools to clean or dump the bottom oil has the risk of grease being exposed to the external environment for a long time and being contaminated, and the operation efficiency is low;

[0005] 2) Chinese application No. 201620644205.8 discloses an oil barrel pumping rod mechanism. Although this patent technology avoids the use of traditional tools to clean up residual oil, it is necessary to observe the bottom oil situation for position adjustment, and the hose at the bottom of the pumping rod cannot ensure that the oil suction ball reaches the bottom of the oil barrel to suck out the bottom oil due to material reasons;

[0006] 3) Chinese application No. 201420443841.5 discloses a self-weight bottom-feed liposuction device. Although this patent technology can rely on a metal disc to press down the liposuction disc, the residual oil in some "dead corners" still needs to be removed by manually rotating the oil suction rod, which does not meet the requirements of full automation;

[0007] 4) Chinese application No. 200720072695.X discloses a device for utilizing residual grease in a grease barrel. This patented technology installs a rubber disc on the oil suction rod to squeeze the grease to the center, but the counterweight on the rubber disc needs to be adjusted in time to ensure that the grease can be squeezed to the center smoothly. Once the counterweight is not adjusted properly or the rubber disc is not sealed well, the grease will not be completely sucked out. Summary of the invention

[0008] In view of the defects existing in the prior art, the purpose of the present invention is to provide a bottom oil suction cleaning device for a lubricating grease barrel, which has a simple design structure, significant oil suction effect, and can reduce energy waste.

[0009] To achieve the above object, the present invention adopts the following technical solution:

[0010] A bottom oil suction cleaning device for a lubricating grease barrel is arranged on the lubricating grease barrel and comprises an oil delivery pipe, a driving motor, a main oil rod and an oil suction pipe assembly;

[0011] The driving motor is arranged on the oil tank cover of the lubricating grease barrel to drive the oil tank cover to rotate reciprocatingly;

[0012] The main oil rod is located in the lubricating grease barrel, the upper end of the main oil rod is connected and fixed to the oil tank cover, and is also connected to the oil delivery pipe, and the lower end of the main oil rod is connected to the oil suction pipe assembly.

[0013] Preferably, the oil suction pipe assembly includes three groups of oil suction pipes of different specifications which are alternately and symmetrically arranged.

[0014] Preferably, each group of the oil suction pipes includes two oil suction pipes.

[0015] Preferably, the lengths of the three groups of oil suction pipes are respectively 1 / 4 of the radius of the grease barrel, 1 / 2 of the radius of the grease barrel, and 3 / 4 of the radius of the grease barrel.

[0016] Preferably, the upper end of the main oil rod is connected to the center position of the fuel tank cover.

[0017] Preferably, the oil tank cover reciprocates along the top edge of the lubricating grease barrel through a stop assembly.

[0018] Preferably, the stop assembly includes a ball disposed at the bottom of the oil tank cover, and a stop block disposed at the top edge of the lubricating grease barrel.

[0019] Preferably, the balls are provided in two groups, symmetrically arranged at the bottom of the fuel tank cover;

[0020] The stop blocks are also provided in two groups, corresponding to the balls.

[0021] Preferably, the reciprocating rotation angle of the fuel tank cover is 40°.

[0022] The bottom oil suction device of a lubricating grease barrel provided by the present invention drives the oil suction device to perform oil suction without dead angles through the oil tank cover with a self-rotating function, effectively solving the problem of incomplete oil suction at the bottom of the barrel, and effectively reducing energy waste. The grease in the barrel is sucked out to the maximum extent, avoiding the problem of incomplete grease suction and residue in the existing system, and the design is simple, safe and reliable, environmentally friendly, and has a wide range of applications, reducing manpower, material resources and production costs, and improving utilization rate.

[0025] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Combination Figure 1 As shown, a bottom oil suction device for a lubricating grease barrel provided by the present invention is installed on a lubricating grease barrel 1, and includes an oil delivery pipe 2, a driving motor 3, a main oil rod 4 and an oil suction pipe assembly 5.

[0027] The driving motor 3 is mounted on the oil tank cover 6 of the lubricating grease barrel 1 to drive the oil tank cover 6 to rotate back and forth.

[0028] The main oil rod 4 is located in the lubricating grease barrel 1. The upper end of the main oil rod 4 is connected and fixed to the oil tank cover 6, and is also connected to the oil pipe 2. The oil pipe 2 is connected to the external oil suction device. The lower end of the main oil rod 4 is connected to the oil suction pipe assembly 5.

[0029] The oil suction pipe assembly 5 comprises three groups of oil suction pipes of different specifications which are alternately and symmetrically arranged, and the oil suction pipes are made of hard material.

[0030] Each set of oil suction pipes includes two oil suction pipes, plus the oil suction port at the lower end of the main oil rod 4, there are a total of 7 oil suction ports.

[0031] The lengths of the three groups of oil suction pipes are respectively 1 / 4 of the radius of the lubricating grease barrel 1, 1 / 2 of the radius of the lubricating grease barrel 1, and 3 / 4 of the radius of the lubricating grease barrel 1.

[0032] The upper end of the main oil rod 4 is connected to the center position of the oil tank cover 6 and is fixedly connected to the oil tank cover 6. A driving motor 3 is installed on the upper part of the oil tank cover 6 to drive the oil tank cover 6 to reciprocate when sucking oil, and the rotation angle is controlled at 40°.

[0033] The oil tank cover 6 reciprocates along the top edge of the lubricating grease barrel 1 through the stopper assembly 7.

[0034] Combination Figure 2 As shown, the stopper assembly 7 includes a ball 71 mounted on the bottom of the oil tank cover 6 , and a stopper block 72 mounted on the top edge of the lubricating grease barrel 1 .

[0035] There are two groups of balls 71 symmetrically arranged at the bottom of the fuel tank cover 6 . There are also two groups of stoppers 72 corresponding to the balls 71 .

[0036] The oil suction operation of the bottom oil suction cleaning device of the present invention is as follows:

[0037] The oil tank cover 6 with the main oil rod 4 installed is placed on the lubricating grease barrel 1, and the grease in the lubricating grease barrel 1 is sucked to the main oil rod 4 through the oil suction port at the lower end of the main oil rod 4 and the oil suction port at the end of the oil suction pipe assembly 5, and then the grease is transported to the required equipment through the oil pipeline 2. Since the grease has a certain viscosity, if there is only one fixed oil suction point, it is impossible to ensure that the grease in the oil barrel is sucked clean, so the bottom oil suction device of the present invention is designed with a total of 7 oil suction points, and at the same time, the oil tank cover 6 drives the oil suction pipe 4 to reciprocate each time the oil is sucked by the driving motor 3 (the stop block 72 can control the stroke of each rotation of the oil tank cover 6), so that the adsorption radius of each oil suction point can be increased, and at the same time, after the oil suction pipes of different lengths are combined in a cross-arranged manner, it can be ensured that the oil suction pipe assembly 5 sucks the position that the adjacent oil suction pipes cannot suck during the rotation process, which can effectively improve the oil suction effect.

[0038] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
