Description
Affiliated technical field
The present invention relates to a kind of diplopore cooling heat radiator that is used for the baffle-type screw rod, belong to the rubber manufacturing machinery field.
Background technology
Use baffle-type screw mixing extruder processing powdered rubber comparatively general in rubber manufacturer at present.According to the textbook introduction, baffle-type screw mixing machine uses an equidistant multiple-threaded screw, is provided with a plurality of split points of being made up of longitudinal and transverse baffle plate in the screw channel, and the screw channel width all changes before and after each split point.The aspect ratio spiral shell rib of baffle plate is low, when sizing material passes through the baffle plate top of split point, be subjected to powerful the shearing, produce a large amount of heats, for avoiding sizing material generation incipient scorch, existing equipment is to get out a thermal hole that communicates with the hollow inwall of screw rod earlier, with cover plate this hole is shut surface grinding again in longitudinal and transverse baffle plate bottom.Because this thermal hole upper end is sealed, enter that cooling water in the hole can't outwards flow out, the heat exchange cooling effect is extremely undesirable, in a single day temperature is controlled and badly just the incipient scorch accident can be taken place, and sizing material is scrapped.
Summary of the invention
Task of the present invention is that design is a kind of simple in structure, practical, be specifically designed to the diplopore cooling heat radiator of baffle-type screw rod, this device is mainly by water inlet pipe 1, preceding supporting disk 2, screw rod 3, inlet opening 4, cover plate 5, apopore 6, water proof cover 7, auxiliary return pipe 8, water control valve 9, swivel joint 10, back supporting disk 11, machine barrel 12, head 13, plug 14 constitutes, longitudinal baffle on the screw rod 3, there are inlet opening 4 and apopore 6 in the lagging place, cavity is left in top, two holes, with cover plate 5 sealings, the afterbody of water inlet pipe 1 and auxiliary return pipe 8 is sleeved in the swivel joint 10, water inlet pipe 1 tail end is equipped with water control valve 9, preceding supporting disk 2 and back supporting disk 11 are used for support and fixed water inlet pipe 1 and assist return pipe 8, inlet opening 4 communicates with screw rod 3 inner chambers, apopore 6 communicated with auxiliary return pipe 8 after drilling screw rod 3 inner chambers again, and water proof cover 7 is sleeved in the apopore 6, leading section is tightened on auxiliary return pipe 8 tube walls.Described diplopore cooling heat radiator, its feature also are the final cooling water backwater path that constitutes a U-shaped like pipe between water proof cover 7-auxiliary return pipe 8 in cavity-apopore 6 under the inlet opening 4-cover plate 5 at screw rod 3 inwalls-longitudinal baffle, lagging place.
Use this device can solve the cooling heat dissipation problem at the longitudinal and transverse baffle plate of baffle-type screw mixing machine place effectively.
Longitudinal and transverse plate washer described here, adding two spacings of being separated by into and out of the water hole that do not require all longitudinal and transverse baffle plate places man-hour must be identical, but as long as finally can constitute the cooling water backwater path of the U-shaped like pipe of sealing at longitudinal and transverse baffle interior.

The specific embodiment
As shown, the water inlet pipe of this device (1) realizes that by preceding supporting disk (2) and back supporting disk (11) suit is connected with auxiliary return pipe (8), water inlet pipe (1) front end external diameter injects in preceding supporting disk (2) endoporus, have in the hole that unillustrated seal is done radial seal among the figure, cooling water can not flow back in the auxiliary return pipe (8) from its between centers cooperation place, therefore, this baffle plate be in when just starting working, in water proof cover (7) pipe not the cooling water with pressure enter.Support claw on back supporting disk (11) external diameter is stuck in the inner chamber of screw rod (3) and plays the supporting ﹠ stablizing effect, and the rear end external diameter of water inlet pipe (1) sliding fit from the endoporus of back supporting disk (11) passes, and screw front end is with plug (14) shutoff.
Longitudinal and transverse baffle plate place is drilled with inlet opening (4) and apopore (6), top, two holes is left cavity, is sealed with cover plate (5), the afterbody of water inlet pipe (1) and auxiliary return pipe (8) is sleeved in the swivel joint (10), water inlet pipe (1) tail end is equipped with water control valve (9), inlet opening (4) communicates with screw rod (3) inner chamber, apopore (6) communicated with auxiliary return pipe (8) after drilling the screw rod inner chamber again, and water proof cover (7) is sleeved in the apopore (6), leading section is tightened on auxiliary return pipe (8) tube wall with instrument.The common backwater path that constitutes a U-shaped like pipe between water proof cover (7) in cavity-apopore (6) under the inlet opening (4) at screw rod (3) inwall-longitudinal and transverse baffle plate place-cover plate (5)-auxiliary return pipe (8).
Screw rod (3) outside is machine barrel (12), and front end is head (13), and head during work (13) and machine barrel (12) are inner all to have independent cooling recirculation system to lower the temperature.
Specific implementation process is as follows: during the work of baffle-type screw mixing machine, the staff opens water control valve (9), cooling water enters water inlet pipe (1) inner chamber through swivel joint (10), flow out from water inlet pipe (1) front end exit again, because screw rod (3) front end has plug (14) shutoff, current just turn around to turn to, flow backward along screw rod (3) inwall, main current are derived the heat on the screw rod body of rod and are taken away in the flow process, and it is also vertical along mobile backward another road current that have pressure of screw rod (3) inwall from what communicate with screw rod (3) inner chamber, the inlet opening at lagging place (4) enters in the cavity under the cover plate (5), from water proof cover (7) endoporus that is sleeved on apopore (6) the inside, flow into the inner chamber of auxiliary return pipe (8) again, swivel joint (10) the change direction of installing by afterbody flows back to recovery tank (H) at last, meanwhile, also flow to recovery tank (H) by screw rod (3) inwall to the cooling water that screw rod (3) afterbody opening part refluxes.
This diplopore cooling heat radiator for the baffle-type screw rod of the present invention has the advantages such as simple in structure, easy to manufacture, that the screw rod integral heat sink is effective, can be used in the transformation and innovative design of existing baffle-type screw rod.
