Underwater pelletizer, particularly SQL series underwater pelletizer, it is the industrial chemicals with molten condition, after water suitably cools off, cuts into a kind of plant equipment of solid particle.(see figure 1).It mainly is made up of cooling feed arrangement (21), cutter sweep (16), discharge device (12), atmospheric control, electric control system.The cooling feed arrangement is made up of startup head (25), a middle thread plate (4), parking plate (5), loam cake (2), shower (3).Start and be provided with water tank (24), startup plate cylinder (23), water valve cylinder (22) (see figure 2) in the head (25).Start plate cylinder (23) and be connected in and start on the plate (1), under the gas effect, can make to start plate (11) rotation, make to start plate and be in operating position or waste discharge position (be threaded to dotted line position is waste discharge among Fig. 1).Water valve cylinder (22) links to each other with water tank (24), under cylinder action, can control cistern water supply or cuts off the water supply.Start on the plate (1) and have many deep-slotted chip breakers, its spacing and quantity are identical with hole count with spacing on the end of extruded band (26), and (end of extruded band is that the industrial chemicals such as polyester of will reaction good molten condition are squeezed into billot under certain pressure, end of extruded band (26) does not belong to stock-cutter under water, is contained in the top of the cooling feed arrangement of stock-cutter under water).One cascade is arranged at water tank (24) top, and its effect is that chemical industry billots such as polyester are cooled off.Have and the deep-slotted chip breaker that starts plate equal number, identical size, uniform distances on middle thread plate (4), the parking plate (5), its effect is to make things convenient for billot to move downward.During billot moved downward, the water of shower (3) ejection continued cooling to it.Shower water can prevent that also billot from beating.When billot arrives parking plate (5), will become outer hard interior soft billot.
Parking plate (5) guiding billot enters cutter sweep (16).
Referring to Fig. 3, cutter sweep is made up of cutting chamber (15), cutting chamber cap (6) and gear (not shown).Cutting chamber and cutting chamber cap fuse by rotating shaft (11), and the cutting chamber cap can rotate around the shaft, so that the cutting chamber cap is opened or is locked.
In the cutting chamber, preceding citation roller (8), back citation roller (19), hobboing cutter (17), stationary knife (18), left locking cylinder (20), right locking cylinder (34, not shown) are housed, a left side rocking arm (10), right rocking arm (10 ', not shown), preceding citation roller is loaded in the rocking arm of the left and right sides, and it is (14) motion around the shaft.On left and right rocking arm, adjustment screw (28) and locking nut (29) are housed, adjustment screw withstands on left and right bearing chamber (30) in the cutting chamber (30 ', not shown), clockwise turn adjustment screw, rocking arm (10,10 ') and bearing chamber (30,30 ') gap are increased, the inhour turn will make its gap reduce.Because preceding citation roller is loaded in the left and right rocking arm, so the adjusting rocking arm just can be regulated the gap between forward and backward citation roller.
Left side abnormity lock (7), right abnormity lock (7 ', not shown), a left side are housed on the cutting chamber to hold out against cylinder (9), the right side and holds out against cylinder (35, Fig. 2 in not shown), when cutting chamber cap in position shown in Figure 3, give left and right locking cylinder right-hand member air feed, left and right locking cylinder will hook cutting chamber by left hook (3) and right hook (3 ') and cover left and right sides special-shaped pin and be locked, at this moment, cutting chamber cap and cutting chamber are connected as a single entity.Then, feed gas, the left and right cylinder operation that holds out against for the left and right cylinder that holds out against, left piston bar 27 and right piston rod (27 ', not shown) will withstand left and right rocking arm respectively, at this moment, and by turn adjustment screw (28), gap requirement with citation roller before and after satisfying realizes normal pelletizing.
Under gear drove, front and back citation roller, hobboing cutter ran well.Gear has realized that the linear velocity of forward and backward citation roller equates.Under forward and backward citation roller clamping, billot is sent into hobboing cutter, tangent with stationary knife, cut out particle, send hopper by transporting water.
In sum, have only when starting plate to be in position shown in Figure 1, the water valve cylinder operation, the cutting chamber cap is locked, and holds out against cylinder operation, and stock-cutter could operate as normal.The coordination of said mechanism is to finish by atmospheric control.
The underwater pelletizer of now having produced, atmospheric control are comparatively complicated, operation inconvenience, and its typical principle is as shown in Figure 4.When gas by water-separating gas filter (41), pressure regulator (40), oil sprayer, gas enters main line, main line divides three bye-passes.Leading up to singly, automatically controlled magnetic valve (32), one-way throttle valve (33), control start plate cylinder (23) and water valve cylinder (22); Lead up to two automatically controlled magnetic valves (38), control left locking cylinder (20) and right locking cylinder (34); Third Road is by pressure regulator (37) and air gauge (36), and a control left side holds out against cylinder (9) and the right side holds out against cylinder (35).When giving magnetic valve (38) one instructions, gas enters left and right locking cylinder through two automatically controlled magnetic valves (38) and subtube, after the locking cylinder work, can make the locking of cutting chamber cap and cutting chamber.Have only after the cutting chamber cap is locked, just allow to connect pressure regulator (37), gas enters through pressure regulator (37) and holds out against cylinder (9,35), and two hold out against cylinder operation.The pelleter structural requirement has only two to hold out against cylinder operation, could adjust the forward and backward citation roller gap of stock-cutter, and after the gap mixed up, pelleter was in granular attitude to be cut.Before the pelletizing instruction issuing, give magnetic valve (32) instruction, start plate cylinder (23) this moment, water valve cylinder (22) is worked simultaneously; start plate (1) and be in the operating position; the water valve cylinder is in the water supply state, and behind the pelleter instruction issuing, pelleter can carry out pelletizing work.After pelletizing work is finished, stop the pelletizing instruction issuing, magnetic valve (32) outage, magnetic valve resets, and will make the startup plate be in the waste discharge position, at this moment, need cutting chamber is cleaned, at this moment give two automatically controlled magnetic valves (38) one instructions, left and right locking cylinder (20, (34) unclamp, the cutting chamber cap can be opened.
Owing to due to the cutting chamber structure, when locking again, pressure regulator (37) must be closed, the cutting chamber cap could safe and reliable locking.Otherwise, the left and right cylinder that holds out against always is in the state of holding out against, the cutting chamber cap holds out against under the cylinder action left and right, rotate to Fig. 5 position, at this moment, even if connect magnetic valve (38), the hook of two locking cylinders (31,31 ') still can't hook the special-shaped pin (7,7 ') in the cutting chamber cap, then cutting chamber cap can't pin, and citation roller gap, front and back also just can't guarantee.
In addition, after the cutting chamber cover lock is tight, also must pressure regulator (37) be opened again, adjust to setting pressure, hold out against cylinder operation, citation roller keeps certain interval before and after just making.At this moment, pelleter just is in granular attitude to be cut.
As seen from the above, after pressure regulator (40) mixed up, after requirement was adjusted in the gap of front and back citation roller, its working procedure can be reduced to: 1, give magnetic valve (32) one instructions, make the startup plate in running order.2, assign the pelletizing instruction, complete machine starts.3, assign halt instruction, 4, unclamp instruction for magnetic valve (38), open the cutting chamber cap.5, clean cutting chamber, 6, close pressure regulator (37), 7, locking cutting chamber cap, 8, adjust pressure regulator (37) to setting pressure.After above-mentioned 8 programs are finished, prepare pelletizing next time.In other words, each working cycles needs 8 programs.The workman must operate by said procedure, just can make pelleter be in normal operating conditions.But because pelleter work-yard of living in temperature is very high, the maloperation phenomenon appears in severe operational environment unavoidably.In the real work, once adjusted pressure regulator (37), and caused the cutting chamber cap not lock, thereby influenced chipping qualities because of the workman forgets.
The objective of the invention is to: simplify procedures, avoid the maloperation phenomenon to take place, guarantee the pelletizing quality.From the pelleter structural analysis as can be known, want to make cutting chamber locking safe and reliable, in the moment that locking cylinder is started working; hold out against cylinder and do not allow work, have only locking after, holding out against cylinder could work; like this, could guarantee that the forward and backward pick-up roll of pelleter gap immobilizes.
Technical scheme of the present invention as shown in Figure 6, atmospheric control has been done improvement, it is characterized in that, behind the main line that water-separating gas filter (41), pressure regulator (40), oil sprayer (39) are housed, the bifurcation pipeline, one branch road is equipped with two automatically controlled magnetic valves (38), is controlling the left and right locking cylinder (20,34) in the cutter sweep.Another branch road is equipped with single automatically controlled magnetic valve (32), one-way throttle valve (33), controlling the startup plate cylinder (23) and the water valve cylinder (22) that cool off in the feed arrangement, starting plate cylinder (23) in control is in the pipeline of operating position, by a threeway, connecting and leading to a shunt that holds out against cylinder (9,35).Like this, be in the operating position when starting the plate cylinder, the left and right cylinder that holds out against just is in the state of holding out against; guaranteed pelleter when pelletizing, the citation roller gap immobilizes, and when cleaning cutting chamber; start plate and be in the waste discharge position, at this moment, hold out against cylinder and just be in relaxation state.After cutting chamber is cleaned and finished, when locking, the not tight phenomenon of cutting chamber cover lock shown in Fig. 5 just can not appear again.
As seen from Figure 6, when gas enters two branch road pipelines through water-separating gas filter (41), pressure regulator (40), oil sprayer (39), one branch road links to each other with two automatically controlled magnetic valves (38), be used for controlling left and right locking cylinder (20) (34), another branch road links to each other with single automatically controlled magnetic valve (32), be used for control startup plate cylinder (23), water valve cylinder (22) and about hold out against cylinder (9) and (35).Magnetic valve (38) is received after the locking instruction, two locking cylinders (20) and (34) work.Then to magnetic valve (32) one work orders, it is in running order to start plate cylinder (22), left and rightly holds out against cylinder (9) and (35) are in the state of holding out against, like this, just guaranteed that forward and backward citation roller gap is in changeless position when normal pelletizing.When pelleter quits work, be subjected to the effect of single automatically controlled magnetic valve (32), start the plate cylinder and be indexed to the waste discharge position automatically, the water valve cylinder is in closed condition, holds out against cylinder and is in releasing orientation.Therefore, after the cleaning cutting chamber finishes, when locking again, just do not held out against the influence of cylinder, and locking that can be safe and reliable has avoided forward and backward at locking cutting chamber cap, the working procedure that need close, adjust pressure regulator (3) respectively.
Adopt atmospheric control of the present invention, simplify the structure, simplified working procedure.Working procedure is now: 1, give magnetic valve (32) one instructions, make startup plate cylinder be in the operating position, the water valve cylinder is in the water supply state.2, assign the pelletizing instruction, complete machine starts.3, assign halt instruction, complete machine stops.4, unclamp instruction for magnetic valve (38), open cutting chamber.5, clean cutting chamber.6, connect magnetic valve (38), locking cutting chamber cap.After above-mentioned 6 programs are finished, prepare pelletizing next time.Make operation sequence become 6, simultaneously, avoided the maloperation phenomenon to take place, also saved a pressure regulator, Pressure gauge and many pipelines and joint etc. by 8.
