Description

Technical Field

[0001] The invention relates to the technical field of latex processing equipment, in particular to a latex and coagulant co-flow device. Background Art

[0002] Whole latex is the main product of latex raw material grade technical graded rubber. Its main production process is: mixing (latex plus coagulant), coagulation, thinning, crimping, granulation, drying, packaging and packaging.

[0003] In the main process of full latex, after the latex is mixed, the concentration (dry rubber content) is adjusted, and the ammonia content is measured, the amount of coagulant needs to be calculated based on the dry rubber content and ammonia content in the latex. If acid coagulation is used, it is generally divided into two categories: coagulation acid and neutralization acid: total acid amount = coagulation acid + neutralization acid. Then, the latex and coagulant (diluted solution or dissolved solution) are mixed evenly, and the emulsion is broken (the latex loses stability) to coagulate. At present, the coagulants used for coagulation mainly include acids, salts, biological coagulants, etc.

[0004] In China and major natural rubber producing countries in Southeast Asia, the mixed latex and coagulant are mixed in a manner that the mixed latex is discharged from the mixing tank by gravity and the coagulant is discharged from the acid water tank by gravity at the same time (commonly known as the "down-tank" operation in processing and production), and the mixed latex and the coagulant aqueous solution are allowed to flow in parallel, mixed evenly during the parallel flow process and the flow in the coagulation tank, and then coagulated in a rectangular coagulation tank.

[0005] The mixing of mixed latex and coagulant in the existing parallel flow technology is based on the assumption of equal liquid level height and equal flow ratio: the liquid level of the mixed latex in the mixing tank is the same as the liquid level of the dilute coagulant solution in the coagulant tank, and by adjusting the caliber adjustment plate on the coagulant outlet pipe, the cross-sectional area of ​​the latex outlet: the cross-sectional area of ​​the coagulant outlet = the volume of the mixing tank: the volume of the coagulant tank = 10:1.

[0006] However, the existing parallel flow technology has the following problems:

[0007] (1) The viscosity of the mixed latex is affected by many factors such as season, climate, rubber tree strain, dry rubber content, preservative type and content, non-rubber components, etc., and varies greatly, while the viscosity of the coagulant solution is relatively stable. Therefore, it is difficult to discharge the mixed latex and coagulant solution in a fixed ratio and ensure that the latex and coagulant are mixed evenly.

[0008] (2) In current production, it is difficult to achieve equal liquid level and flow rate of mixed latex and coagulant solution, and latex and coagulant cannot be discharged at the same time during the tank discharge, resulting in uneven coagulation. During the tank discharge process, it is necessary to manually adjust the opening of the first valve at the outlet of the latex mixing tank or coagulant tank to control the discharge amount of the mixed latex and coagulant to meet the ratio requirements. The simplest method is to block the outlet of the mixing tank or coagulant tank with a rubber plug to reduce the discharge amount of the mixed latex or coagulant accordingly. Such operation is troublesome and difficult to achieve the purpose of uniform mixing.

[0009] (3) Uneven operation of the lower tank results in uneven coagulation quality: some clots have excessive coagulant, resulting in higher hardness, while others have insufficient coagulant, resulting in clots that are too soft, incomplete coagulation, "white water", "rotten bottom" and other phenomena. The quality of semi-finished products and finished products processed in subsequent processes is unstable and unqualified, and the product completion rate and qualified rate are reduced. At the same time, abnormal coagulation increases the difficulty of sewage treatment.

[0010] For example, a method for coagulating natural rubber fresh latex by adding coagulation liquid with double parallel flow is disclosed in patent number CN201110354448.X, which discloses coagulating fresh latex by a double parallel flow coagulation natural fresh latex system. The double parallel flow coagulation natural fresh latex system is composed of four parts: a fresh latex mixing tank, an acid water tank, a microbial coagulation liquid tank and a double parallel flow fresh latex coagulation device. The fresh latex mixing tank, the acid water tank and the microbial coagulation liquid tank are connected to the double parallel flow fresh latex coagulation device through a connecting pipe, and each is controlled by a switch. When the switches in the system are turned on at the same time, The fresh latex flowing out of the mixing tank is first mixed with the formic acid / acetic acid flowing out of the acid water tank, and the formic acid / acetic acid is neutralized with the ammonia of the fresh latex, and then the microbial coagulation liquid flowing out of the microbial coagulation liquid tank is mixed with the fresh latex, and then flows into the latex coagulation tank, and the microorganisms grow and reproduce in the mixed latex, destroy the stability of the latex and realize the coagulation of the fresh latex, and the neutralization acid of the acid water tank and the microbial coagulation liquid of the microbial coagulation liquid tank are diluted with water to the same height as the fresh latex in the fresh latex mixing tank. The output of the fresh latex and formic acid / acetic acid is controlled by the corresponding first valve, which is troublesome to operate and has a poor mixing effect. Summary of the invention

[0047] Working principle:

[0048] (1) Before the latex enters the latex mixing tank 19 and the mixed latex and coagulant are mixed and coagulated, the latex outflow plug valve 39, the coagulant plug valve 40, the latex inflow plug valve 36 and the water inlet valve 4 are in the closed state; the water inlet switch 41 and the coagulant switch 42 on the electric control box 5 are in the manual state, and the power switch 43 is in the cut-off state.

[0049] (2) When the amount of latex in the latex unloading tank reaches a certain level, the latex inflow plug valve 36 is opened, and the latex flows from the unloading tank into the latex mixing tank 19.

[0050] (3) Turn on the power switch 43 on the electric control box 5 to turn on the power, and switch the water inlet switch 41 to the automatic state. As the latex liquid level in the latex mixing tank 19 rises, the float 15 and the float guide rod 16 rise vertically along the bracket 6, and the main board 23 descends along the main board guide rod 31. Since the coagulant tank 20 is not filled with water at this time, the balance bar 3 rotates counterclockwise around the main board 23, triggering the water inlet switch 12, the water inlet valve 4 opens, and the coagulant dilution water enters the coagulant tank 20.

[0051] (4) The dilution water level in the coagulant pool 20 rises until the liquid level is first level and then slightly higher than the liquid level in the mixing pool. The balance bar 3 rotates clockwise, triggering the water inlet switch 13, the water inlet valve 4 is closed, and the water inlet stops. This process is repeated, and the dilution water level rises with the latex liquid level in the latex mixing pool 19, reaching a substantially level liquid level. Subsequently, the amount of coagulant is calculated based on the dry glue content, preservative content and other indicators of the latex in the mixing pool and added to the coagulant pool 20. The coagulant liquid level will rise slightly. Subsequently, after adding latex dilution water and defoaming water to the latex mixing pool 19, the liquid level in the coagulant pool 20 automatically follows the rise and becomes level with the latex liquid level in the mixing pool. Through the above two steps (3) and (4), latex mixing is achieved to obtain mixed latex, and coagulant dilution is achieved.

[0052] (5) Switch the water inlet switch 41 on the electric control box 5 to the manual state, and switch the coagulant switch 42 to the automatic state. Press the latex opening button 44, the electric push rod 1 26 contracts, the latex outflow plug valve 39 rises and opens, the latex flows out of the latex mixing pool 19, falls into the mixing bucket 1 through the latex outflow pipe 37, and then flows out through the flow channel 2 and falls into the coagulation tank (not marked). At the same time, the latex liquid level in the latex mixing pool 19 drops, the balance bar 3 rotates clockwise, triggering the coagulant switch 10, the electric push rod 2 29 contracts, the coagulant plug valve 40 is fully opened (100%), the coagulant flows out of the coagulant pool 20, falls into the mixing bucket 1 through the coagulant outflow pipe 38, mixes with the mixed latex, and then flows out through the flow channel 2 and falls into the coagulation tank (not marked), and further mixes with the mixed latex in the process of flowing through the flow channel 2 and falling into the coagulation tank (not marked).

[0053] (6) If the outflow of coagulant is relatively large, the balance bar 3 rotates counterclockwise, triggering the coagulant switch 11, the electric push rod 29 extends, the coagulant plug valve 40 closes to about 70%, the outflow of coagulant is relatively reduced, and the liquid level is restored to be level with the latex. If the coagulant liquid level is higher than the latex, the balance bar 3 rotates clockwise, triggering the coagulant switch 10, the electric push rod 29 contracts, and the coagulant plug valve 40 opens (100%). This control is repeated to ensure that the latex liquid level and the coagulant liquid level remain relatively level.

[0054] (7) If any abnormality occurs during operation, the latex outflow plug valve 39 and the coagulant plug valve 40 can be opened or closed manually.

[0055] (8) If two or more coagulants are mixed with latex, the components such as the float 15 and the switch assembly 9 can be expanded to achieve liquid level balance in three or more pools and uniform mixing of three or more liquids. Therefore, the parallel use of the device can control the liquid level balance and (or) uniform mixing in three or more containers.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
