Description

Technical Field

[0001] This utility model belongs to the field of sizing machine technology, and in particular relates to a parallel sizing machine sizing supply system. Background Technology

[0002] During production, warp yarns are sized using a sizing machine. When sizing, the sizing machine typically immerses the warp yarns in sizing material through a sizing device or sprays the sizing material onto a sizing roller before sizing the warp yarns.

[0003] For example, Chinese utility model CN203270285U discloses a dual-sizing tank dual-sizing material supply device. By adding a sizing pipe, two sizing liquids supplied from different sources are formed. The liquids are then controlled by an electrically controlled valve to enter different sizing tanks, enabling the sizing machine to achieve differentiated sizing of two or the same warp yarns using two different sizing formulas.

[0004] However, the two sizing tanks of the existing sizing machine in the weaving workshop are supplied with sizing through independent pipelines and sizing pumps. When one of the sizing pumps fails, the machine needs to be stopped for repair and replacement, which causes the equipment to stop and seriously affects the production efficiency of the sizing machine. Utility Model Content

[0005] The purpose of this utility model is to provide a parallel sizing machine slurry supply system. By connecting a three-way valve 1 and a three-way valve 6 in series in slurry supply pipeline 1 and slurry supply pipeline 2 respectively, and using a pipe to connect the port of three-way valve 1 to sizing tank 2, and the port of three-way valve 6 to sizing tank 1 through a pipe, the system can supply slurry to both sizing tanks by the remaining slurry pump when either slurry pump 1 or slurry pump 2 fails. This solves the problem that existing slurry pumps require machine shutdown for repair after failure, which affects production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a parallel sizing machine sizing system, comprising a sizing trough 1, a sizing trough 2, and a sizing tank. The sizing tank supplies sizing to the sizing trough 1 via a sizing supply pipeline 1, and supplies sizing to the sizing trough 2 via a sizing supply pipeline 2. A sizing pump 1 is connected in series in the sizing supply pipeline 1, and a sizing pump 2 is connected in series in the sizing supply pipeline 2. A three-way valve 1 is connected in series between the outlet end of the sizing pump 1 and the sizing trough 2, and a three-way valve 6 is connected in series between the outlet end of the sizing pump 2 and the sizing trough 2 in the sizing supply pipeline 2. Port 1 of the three-way valve 1 is connected to the sizing trough 2 via a pipe, and port 1 of the three-way valve 6 is connected to the sizing trough 1 via a pipe.

[0008] In a preferred embodiment of this utility model, a three-way valve seven is connected in series between the slurry pump two and the three-way valve six in the second slurry supply pipeline, and a centrifugal pump is connected in series through a pipeline at one port of the three-way valve seven. In the first slurry supply pipeline, a three-way valve two is connected in series between the slurry pump one and the three-way valve one, and a three-way valve two is connected in series through a pipeline at one port of the three-way valve seven and the centrifugal pump. The outlet end of the centrifugal pump is connected to the first slurry supply pipeline through a pipeline, and the connection point is located between the three-way valve one and the three-way valve two.

[0009] As a preferred technical solution of this utility model, a three-way valve is connected in series at the outlet end of the centrifugal pump, and one port of the three-way valve is connected to the return slurry tower through a pipeline.

[0010] As a preferred embodiment of this utility model, a drain valve is connected in parallel to the pipeline between the slurry pump and the slurry storage tank.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model connects three-way valve one and three-way valve six in series in slurry supply pipeline one and slurry supply pipeline two, respectively. The three-way valve one port is connected to slurry yarn tank two through a pipe, and the three-way valve six port is connected to slurry yarn tank one through a pipe. This allows the remaining slurry pump to supply slurry to the two slurry yarn tanks when slurry pump one or slurry pump two fails, thereby achieving maintenance without stopping the machine and effectively ensuring the overall production efficiency.

[0013] 2. By connecting a centrifugal pump in parallel between slurry supply pipeline 1 and slurry supply pipeline 2, and by controlling three-way valve 2 and three-way valve 7, the centrifugal pump and slurry pump 1 or slurry pump 2 can be coordinated to supply slurry, thereby increasing the slurry supply speed and effectively reducing the slurry supply time, thus effectively improving the overall production efficiency.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Example 1

[0023] Please see Figure 1 As shown, this utility model is a parallel sizing machine sizing system, including a sizing trough 10, a sizing trough 20, and a sizing tank. The sizing tank supplies sizing to the sizing trough 10 through a sizing supply pipeline 101, and supplies sizing to the sizing trough 20 through a sizing supply pipeline 201.

[0024] A grout supply pipeline 101 is connected in series with a grout pump 3, and a drain valve is connected in parallel between the grout pump 3 and the grout storage tank. A grout supply pipeline 201 is connected in series with a grout pump 8, and a three-way valve 1 is connected in series between the outlet end of grout pump 3 in grout supply pipeline 101 and the grout trough 10, and a three-way valve 6 is connected in series between the outlet end of grout pump 8 in grout supply pipeline 201 and the grout trough 20.

[0025] Among them, the first port of the three-way valve 1 is connected to the second sizing tank 20 through a pipe, and the first port of the six-way valve 6 is connected to the first sizing tank 10 through a pipe. When the first sizing pump 3 or the second sizing pump 8 fails, the remaining sizing pumps supply sizing to the two sizing tanks, thereby achieving maintenance without stopping the machine and effectively ensuring the overall production efficiency.

[0026] Specifically, if the grout pump 13 malfunctions, and the grout pump 28 is working normally, the grout is transported through the grout pump 28 and the grout supply pipeline 201. The grout enters the grout trough 20 through the three-way valve 6. After the grouting of the grout trough 20 is completed, the three-way valve 6 is switched so that the grout enters the grout trough 10 through the grout pump 28 and the three-way valve 6.

[0027] When grout pump 28 fails, and grout pump 3 operates normally, grout is transported through grout pump 3 and grout supply pipeline 101. The grout enters the grouting tank 10 through three-way valve 1. After grouting is completed, three-way valve 1 is switched so that grout enters the grouting tank 20 through grout pump 3 and three-way valve 1. This ensures normal equipment operation even if one of the grout pumps fails.

[0028] Example 2

[0029] like Figure 2 As shown, based on Example 1, a three-way valve 7 is connected in series between the slurry pump 28 and the three-way valve 6 in the slurry supply pipeline 201, and a centrifugal pump 5 is connected in series through a pipeline at one port of the three-way valve 7.

[0030] In the grout supply pipeline 101, a three-way valve 2 is connected in series between the grout pump 3 and the three-way valve 1. One port of the three-way valve 2 is connected to the pipeline between the three-way valve 7 and the centrifugal pump 5 through a three-way connector.

[0031] The outlet end of centrifugal pump 5 is connected to slurry supply pipeline 101 via a pipe and a tee joint, and the connection point is located between tee valve 1 and tee valve 2. In addition, tee valve 4 is connected in series at the outlet end of centrifugal pump 5, and one port of tee valve 4 is connected to the return slurry tower via a pipe.

[0032] When grout pump 13 fails and grout pump 28 is working normally, switch three-way valve 7 to make grout pump 28 and centrifugal pump 5 form a series circuit, while disconnecting from three-way valve 6. At this time, grout pump 28 and centrifugal pump 5 are started simultaneously. By using grout pump 28 and centrifugal pump 5 to supply grout synchronously and collaboratively, the grout supply speed is greatly improved. The grout enters grout supply pipeline 101 through three-way valve 4, and then the grout is injected into grout trough 10 or grout trough 20 through three-way valve 1.

[0033] When grout pump 28 fails and grout pump 3 is working normally, switch three-way valve 7 to disconnect grout pump 28 from centrifugal pump 5. At the same time, switch three-way valve 22 to form a series circuit between grout pump 3 and centrifugal pump 5. Grout pump 3 and centrifugal pump 5 supply grout synchronously and in coordination. The grout passes through grout pump 3, three-way valve 22, centrifugal pump 5 and three-way valve 4 in sequence into grout supply pipeline 101. Then, switch three-way valve 1 to inject the grout into grout trough 10 or grout trough 20.

[0034] At the same time, by switching the three-way valve 6, the slurry supply pipeline 101 and the slurry supply pipeline 201 can be connected, thereby enabling simultaneous slurry supply to the slurry tank 10 or the slurry tank 20. For example, if the slurry is injected into the slurry tank 10 through the three-way valve 1, a portion of the slurry will enter the slurry tank 20 through the three-way valve 6, thus achieving synchronous slurry supply. By utilizing the slurry supply of the centrifugal pump 5, the slurry suction efficiency can be improved, thereby reducing the overall slurry supply time.

[0035] In addition, when neither grout pump 13 nor grout pump 28 malfunctions, grout pump 13 or grout pump 28 can be selected to supply grout in coordination, thereby further improving grout supply efficiency and reducing grout supply time.

[0036] In actual use, the centrifugal pump 5 has the following characteristics: pumping speed: 2900 rpm, pumping capacity: 14.4 m³ / h, pumping head: 6-12 m; transmission method: direct motor drive stainless steel centrifugal pump; pump rotation direction: clockwise when viewed from the suction inlet towards the motor end; motor power: 2 kW, voltage: 380V, frequency: 50 Hz, speed: 2900 r / min; electrical equipment: to be provided by the user according to the specific conditions of the workshop.

[0037] Previously, filling the sizing tank during startup took 40 minutes; with the parallel centrifugal pump 5, this is reduced to just 10 minutes, completing the sizing machine startup without altering the existing piping, thus meeting the process requirements of the new sizing material. The parallel centrifugal pump 5 replaces the faulty sizing pump for sizing, allowing for normal operation without cranking the machine. Maintenance and replacement are performed during the next cylinder startup interval. The sizing machine efficiency is not affected by the sizing pump failure, stabilizing production and improving the machine's operating efficiency.

[0038] Furthermore, it can reduce sizing quality problems caused by malfunctions in the sizing machine's own sizing supply system, thereby stabilizing product quality and improving sizing speed.
