Description

Technical Field

[0001] The utility model relates to the technical field of cooling water tanks, in particular to a cooling spray box for producing PVC pipes. Background Art

[0002] PVC pipes are formed by hot extrusion. After forming, the temperature is high and needs to be quickly cooled and shaped. In the prior art, cooling water is sprayed onto the surface of the PVC pipe through a spray pipe in a cooling spray box to cool it down. The cooling water is circulated and cooled through a chiller to achieve the purpose of heat exchange and cooling of the high-temperature PVC pipe.

[0003] At present, the spray pipes of most cooling spray boxes on the market directly spray water columns. When the water column hits the surface of the PVC pipe, splashback will occur. Therefore, the contact time and contact effect between the cooling water and the PVC pipe are not sufficient. If you want to increase the contact time, you need to reduce the spray pressure of the cooling water, which will reduce the flow rate of the cooling water, causing the cooling water circulation speed to decrease, and the cooling time is forced to increase, which is a loss of one thing while losing another. Therefore, under the premise of not affecting the cooling water circulation speed, in order to improve the contact effect and increase the contact time between the cooling water and the PVC pipe, a new type of PVC pipe production cooling spray box is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a PVC pipe production cooling spray box, which is used to improve the contact effect and increase the contact time between cooling water and PVC pipes without affecting the cooling water circulation speed.

[0007] The inner walls of the box body and the box cover are fixedly connected to two connecting plates located above and below the PVC pipe through fixing frames respectively. The two connecting plates located above and below the PVC pipe are fixedly connected through bow plates respectively. The connecting plates are fixedly connected to absorbent sponge pads wrapped above and below the PVC pipe.

[0008] Preferably, the box body and the box cover are movably connected via a hinge on the back, and buckles are provided on the front sides of the box body and the box cover.

[0009] Preferably, the arched plate is arc-shaped, and the inner diameter of the arched plate is larger than the outer diameter of the PVC pipe.

[0010] Preferably, the two water-absorbing sponge pads are interference fit with the PVC tube.

[0011] Preferably, it also includes a spray sealing plug, which is movably plugged into the entrance end of the PVC pipe.

[0012] Preferably, the end of the spray sealing plug located outside the PVC pipe is in the shape of a bullet.

[0013] Preferably, the spray sealing plug is provided with an anti-slip groove along the circumferential direction on the surface of one end outside the PVC tube.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model keeps the spraying speed and pressure of cooling water unchanged, sprays cooling water on the water-absorbing sponge pad, and the PVC pipe is transported through between two water-absorbing sponge pads. The water-absorbing sponge pad full of cooling water is wrapped on the PVC pipe, so as to achieve the effect of all-round contact between the cooling water and the PVC pipe, and also increase the contact time between the cooling water and the PVC pipe, improve the cooling efficiency, and achieve the purpose of improving the contact effect and increasing the contact time between the cooling water and the PVC pipe without affecting the cooling water circulation speed.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-6 As shown, the utility model provides a technical solution: a PVC pipe production cooling spray box, comprising a box body 1, a box cover 2 and a spray sealing plug 15, the box body 1 and the box cover 2 are movably connected by a hinge 13 on the back, and buckles 14 are provided on the front of the box body 1 and the box cover 2 for easy opening and closing, and grooves for the PVC pipe 3 to enter are provided on both sides of the box body 1 and the box cover 2, and the PVC pipe 3 enters from the left groove and exits from the right groove.

[0025] The inner walls of the box body 1 and the box cover 2 are both installed with a spray pipe 4, and one side of the inner wall of the box body 1 and the box cover 2 is installed with a connecting pipe 5 connected to the spray pipe 4. The two connecting pipes 5 are connected to the water inlet pipe 7 through a connecting hose 6. The side of the bottom of the box body 1 away from the water inlet pipe 7 is connected to the water outlet pipe 8. The cooling water circulates and cools down through the chiller, enters through the water inlet pipe 7, and flows back through the water outlet pipe 8.

[0026] The inner walls of the box body 1 and the box cover 2 are respectively fixedly connected with two connecting plates 10 located above and below the PVC pipe 3 through a fixing frame 9, which serve as a supporting frame for the water-absorbing sponge pad 12. The two connecting plates 10 located above and below the PVC pipe 3 are respectively fixedly connected through an arch plate 11. The arch plate 11 is arc-shaped, and the inner diameter of the arch plate 11 is larger than the outer diameter of the PVC pipe 3. When the PVC pipe 3 is inserted, the water-absorbing sponge pad 12 has space to deform upward and downward. The connecting plates 10 are fixedly connected with water-absorbing sponge pads 12 wrapped above and below the PVC pipe 3. The two water-absorbing sponge pads 12 are interference fit with the PVC pipe 3, thereby increasing the contact effect with the PVC pipe 3.

[0027] The spray sealing plug 15 is movably inserted into the entrance end of the PVC pipe 3. The end of the spray sealing plug 15 located outside the PVC pipe 3 is in the shape of a bullet. The surface of the end of the spray sealing plug 15 located outside the PVC pipe 3 is circumferentially provided with an anti-slip groove for insertion into the insertion end of the PVC pipe 3 to prevent cooling water from entering the interior of the PVC pipe 3 and causing pollution.

[0028] Working principle: At the end of the hot-extruded PVC pipe 3, a spray sealing plug 15 with matching installation size is inserted, the PVC pipe 3 enters from the groove on the left side of the box body 1, is inserted between the two adjacent water-absorbing sponge pads 12 above and below and transported to the right, and is output from the groove on the right side. The cooling water enters the spray pipe 4 through the water inlet pipe 7, the connecting hose 6 and the connecting pipe 5 and is sprayed onto the water-absorbing sponge pad 12. The water-absorbing sponge pad 12 will be filled with cooling water. Under the action of the water-absorbing sponge pad 12, the cooling water is fully in contact with the PVC pipe 3, ensuring the contact effect and contact time, thereby improving the cooling and heat exchange effect.
