Description

Technical Field

[0001] The utility model relates to a joint, in particular to a joint for a centrifuge, and more particularly to a new type of joint dedicated for feeding of a centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Traditionally, a centrifuge has a connector at the head of the feed pipe to connect the material conveyor and the synchronous delivery of liquid medicine (such as flocculants). Traditional centrifuge feed connectors (such as Fig. 9 The following problems exist:

[0003] 1). It occupies a large area. Since the dosing pipe, flushing pipe and joint pipe on the traditional joint are set at an acute angle, it occupies a large space and is inconvenient to use;

[0004] 2). When the centrifuge is stopped, the liquid pressure head loss in the spiral feed chamber is large, and the material will flow back to the feed joint, thereby blocking the dosing pipe and the flushing pipe, and seriously causing contamination of the dosing and flushing pipes;

[0005] 3). As the traditional joints need to connect the dosing pipe and the flushing pipe, the pipeline layout is chaotic, which is not conducive to the installation and maintenance of the pipeline. Utility Model Content

[0006] The utility model aims to solve the shortcomings of the above-mentioned prior art and provide a new type of centrifuge feed special connector which is easy to install and use and will not cause blockage of the dosing pipe port and the flushing pipe port by materials, thereby meeting the requirements of easy use, easy installation and no blockage of the dosing pipe port and the flushing pipe port.

[0007] The utility model adopts a technical solution to solve the technical problem: the new centrifuge feed special joint comprises a sludge feed pipe, the sludge feed pipe is a curved pipe bent at 90 degrees, a conical pipe with a small outside and a large inside is fixed to the discharge end of the sludge feed pipe, a first assembly flange is fixed on the conical pipe, and a second assembly flange is fixed to the feed end of the sludge feed pipe; a dosing pipe fitting is installed on one side of the sludge feed pipe, and a flushing pipe fitting is symmetrically installed on the other side of the sludge feed pipe; the dosing pipe fitting comprises a first feed pipe arranged transversely and perpendicularly to the sludge feed pipe, a first The inlet pipe is connected to a second inlet pipe which is arranged transversely and perpendicularly to the first inlet pipe, the second inlet pipe is connected to a third inlet pipe which is arranged longitudinally and perpendicularly to the second inlet pipe, and a third assembly flange is fixed to the top end of the third inlet pipe; the flushing pipe fittings include a fourth inlet pipe which is arranged transversely and perpendicularly to the sludge feed pipe, the fourth inlet pipe is connected to a fifth inlet pipe which is arranged transversely and perpendicularly to the fourth inlet pipe, the fifth inlet pipe is connected to a sixth inlet pipe which is arranged longitudinally and perpendicularly to the fifth inlet pipe, and a fourth assembly flange is fixed to the top end of the sixth inlet pipe; check valves are installed at both the third assembly flange and the fourth assembly flange. The function of the conical tube here is to increase the output pressure of the material, so that the material speed when it is transported to the feed pipe and sprayed into the barrel of the screw propeller is faster, which can avoid material blockage; there are dosing pipes here for dosing materials (such as flocculants), so as to speed up and thoroughly separate the solid and liquid; the function of the flushing pipes here is to flush the used feed pipes and joints; the function of the check valve here is to further prevent a small amount of material from flowing back to the dosing pipe or the flushing pipe; the check valve here can only make the liquid flow toward the feed pipe, and cannot make the liquid flow back to the dosing delivery pipe or the flushing delivery pipe; the check valve here is an existing product on the market, and products from companies such as Watts Water Industry Group and Lianggong Valve Group Co., Ltd. can be selected.

[0008] Further improvement, the connection between the first inlet pipe and the sludge feed pipe and the connection between the fourth inlet pipe and the sludge feed pipe are both installed with spherical baffles, and the bottoms of the two spherical baffles are both opened with discharge openings. The function of the spherical baffles and the discharge openings here is to further prevent the material from flowing back to the dosing pipe fittings and the flushing pipe fittings.

[0009] Further improvement, a group of tapered holes with intervals and larger inside and smaller outside are opened on the spherical surfaces of the two spherical baffles. The function of the tapered holes here is to spray out the liquid medicine or flushing liquid quickly and at high pressure to avoid the material being blocked at the spherical baffle.

[0010] The beneficial effects of the utility model are:

[0011] 1). Clear layout and easy installation;

[0012] 2). It will not cause blockage to the dosing pipe and flushing pipe, and will not cause pollution to the dosing delivery pipe and flushing delivery pipe;

[0013] 3). It can increase the conveying pressure of the material, so that the material speed when it is conveyed to the feeding pipe and sprayed into the barrel of the screw propeller is faster, which can effectively avoid material blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] Referring to the attached drawings: this new type of centrifuge feed special joint includes a sludge feed pipe 1, which is a curved pipe bent at 90 degrees. A conical tube 1-1 with a small outside and a large inside is fixed to the discharge end of the sludge feed pipe 1, and a first assembly flange 2 is fixedly installed on the conical tube 1-1. A second assembly flange 3 is fixedly installed on the feed end of the sludge feed pipe 1; a dosing pipe 4 is installed on one side of the sludge feed pipe 1, and a flushing pipe 5 is symmetrically installed on the other side of the sludge feed pipe 1; the dosing pipe 4 includes a first inlet pipe 4-1 arranged transversely and perpendicularly to the sludge feed pipe 1, and the first inlet pipe 4-1 is connected to a second inlet pipe 4-1 arranged transversely and perpendicularly to the first inlet pipe 4-1. The second inlet pipe 4-2 is connected to a third inlet pipe 4-3 which is vertically arranged with the second inlet pipe 4-2, and a third assembly flange 4-4 is fixed to the top of the third inlet pipe 4-3; the flushing pipe 5 includes a fourth inlet pipe 5-1 which is horizontally vertically arranged with the sludge feeding pipe 1, the fourth inlet pipe 5-1 is connected to a fifth inlet pipe 5-2 which is horizontally vertically arranged with the fourth inlet pipe 5-1, the fifth inlet pipe 5-2 is connected to a sixth inlet pipe 5-3 which is vertically arranged with the fifth inlet pipe 5-2, and a fourth assembly flange 5-4 is fixed to the top of the sixth inlet pipe 5-3; check valves 8 are installed at both the third assembly flange 4-4 and the fourth assembly flange 5-4.

[0026] Spherical baffles 6 are installed at the connection ports between the first inlet pipe 4 - 1 and the sludge feed pipe 1 and at the connection ports between the fourth inlet pipe 5 - 1 and the sludge feed pipe 1 , and discharge openings 6 - 1 are opened at the bottoms of the two spherical baffles 6 .

[0027] A group of tapered holes 6 - 2 which are spaced apart and are larger inside and smaller outside are formed on the spherical surfaces of the two spherical baffles 6 .

[0028] Working principle of the utility model: When the material (thin sludge) is transported through the material conveying pipe 9 and reaches the cone tube 1-1 through the sludge feeding pipe 1, it can enter the feeding pipe 7 under high pressure through the pressurization of the cone tube 1-1 and be sprayed into the cylinder of the screw propeller through the outlet of the feeding pipe 7 under high pressure. At the same time, the dosing pipe 4 continuously conveys the liquid (such as flocculant, etc.) through the dosing conveying pipe 10 and mixes it with the material to accelerate the flocculation and sinking, so that the solid-liquid separation is more thorough; when the centrifuge is shut down, the liquid pressure head loss in the spiral feeding chamber is large, and the material will flow back to the feeding joint. At this time, the material is blocked by the spherical baffle 6 and the check valve 8 and will not flow back to the dosing conveying pipe 10 and the flushing conveying pipe 11, thereby ensuring that the dosing conveying pipe 10 and the flushing conveying pipe 11 are not contaminated. When the material conveying is completed, clean water is transported through the flushing conveying pipe 11, which can efficiently flush the feed pipe 7, the screw propeller and the drum. Operation, and through the action of the check valve 8 (which can only be transported outwards and cannot flow back inwards), clean water will not flow into the dosing conveying pipe 10 and cause pollution; since the discharge opening 6-1 is located at the bottom of the spherical baffle 6, the amount of material that will flow back into the discharge opening 6-1 is small (the first inlet pipe 4-1 and the fourth inlet pipe 5-1 are vertically arranged with the sludge feed pipe 1, the extrusion force of the sludge is small, and most of the sludge will flow back to the material conveying pipe 9), and the additional tapered hole 6-2 is large inside and small outside, so the amount of material squeezed into the dosing pipe fitting 4 and the flushing pipe fitting 5 through the tapered hole 6-2 is also very small (the impact of the liquid medicine and clean water can immediately flush away the small amount of material located at the tapered hole 6-2 and the discharge opening 6-1), and through the insurance effect of the check valve 8, the material will not enter the dosing conveying pipe 10 and the flushing conveying pipe 11, and cause pollution to the dosing conveying pipe 10 and the flushing conveying pipe 11 (such as Figure 8 As shown), the utility model has a clear layout and is easy to install. It will not cause blockage to the dosing pipe and the flushing pipe, will not cause pollution to the dosing delivery pipe and the flushing delivery pipe, can increase the delivery pressure of the material, so that the material speed when it is transported to the feeding pipe and sprayed into the cylinder of the spiral propeller is faster, which can effectively avoid material blockage and is worthy of popularization and application.
