Description

Circulating cooling system

Technical Field

The utility model relates to a plastics manufacturing technology field specifically discloses a circulative cooling system.

Background

Plastic processing operations typically include compounding, forming, joining, assembling, mechanical finishing, etc., wherein the forming step is typically accomplished by a plastic extruder. The plastic is generally in a strip shape after being formed, and enters a cutting procedure after being cooled, and the plastic is cut into particles by a cutting machine. The existing plastic cooling system comprises a water tank, and strip-shaped plastics are soaked in the water tank for cooling. Most of VOC in the strip-shaped plastic is discharged in the screw machine barrel, but a small amount of VOC remains, the VOC can be absorbed by cooling water in the water tank, and the VOC content in the cooling water is high after the cooling water is recycled for multiple times, so that the environment is easily polluted, and the physical health of workers in a workshop is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a circulative cooling system to solve the high problem of VOC content in the cooling water.

In order to achieve the above object, the basic scheme of the utility model is:

the circulating cooling system comprises a cooling tank and a cooling box, wherein a water inlet pipe and a water outlet pipe are communicated in the cooling tank, a spray header is arranged at the upper end in the cooling box and communicated with the water outlet pipe, and the lower end of the cooling box is communicated with the water inlet pipe; the upper end of the cooling box is provided with an air suction opening, an air suction pump is arranged on the air suction opening, and two air inlets are respectively formed in two side walls of the cooling box.

Optionally, activated carbon particles are provided in the cooling box.

Optionally, the level is equipped with first sieve and second sieve in the cooler bin, and first sieve is located second sieve top, and all holds active carbon particle on first sieve and the second sieve.

Optionally, the first screen deck is spherical, curved downward.

Optionally, a one-way air valve is arranged on the air inlet.

The beneficial effect of this basic scheme lies in:

in the scheme, the cooling water can be sprayed out of the spray header and falls to the bottom of the cooling box, the air pump can pump air out of the cooling box, the air flows upwards from the lower part, the flowing direction of the air and the flowing direction of the cooling water are opposite, the temperature of the cooling water can be effectively reduced, and a small part of VOC is evaporated and pumped out of the cooling box. The cooling water can contact with the active carbon granule in the cooler bin, and the VOC in the cooling water can be absorbed to the active carbon granule, greatly reduces the VOC content in the cooling water.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a cooling tank 1, a water inlet pipe 2, a water outlet pipe 3, a liquid pump 4, a cooling box 5, an air suction opening 6, an air suction pump 7, an air inlet 8, a one-way air valve 9, a spray header 10, a first sieve plate 11 and a second sieve plate 12.

Example one

The embodiment is basically as shown in fig. 1 and fig. 2:

the circulating cooling system comprises a cooling tank 1 and a cooling box 5, wherein a water inlet pipe 2 and a water outlet pipe 3 are communicated in the cooling tank 1. The cooling tank 1 is used for cooling strip-shaped plastics, the strip-shaped plastics move from left to right, the water inlet pipe 2 is positioned on the left side wall of the cooling tank 1, and the water outlet pipe 3 is positioned on the right side wall of the cooling tank 1.

The upper end of the interior of the cooling box 5 is provided with a spray header 10, the spray header 10 is communicated with the water outlet pipe 3, and the lower end of the cooling box 5 is communicated with the water inlet pipe 2. All be equipped with liquid pump 4 on outlet pipe 3 and the inlet tube 2, the liquid pump 4 on the outlet pipe 3 can take cooling water out from cooling bath 1 and carry the cooling tank 5 in, and liquid pump 4 on the inlet tube 2 can take out the water in the cooling tank 5 and carry in cooling bath 1. An air suction opening 6 is formed in the upper end of the cooling box 5, and an air suction pump 7 is arranged on the air suction opening 6. Two air inlets 8 are respectively arranged on two side walls of the cooling box 5, a one-way air valve 9 is arranged on the air inlets 8, and the one-way air valve 9 only supplies air to enter the cooling box 5 from the outside. The subsequent VOC content detection that can carry out of the gas that pumps out in aspiration pump 7 detects up to standard and can directly discharge, not up to standard can carry out next step purification treatment.

The horizontal fixed first sieve 11 and the second sieve 12 of being equipped with in cooler bin 5, first sieve 11 is located second sieve 12 tops, and air intake 8 is located between first sieve 11 and the second sieve 12, and all has contained the active carbon granule on first sieve 11 and the second sieve 12. The first screen deck 11 is in the shape of a downwardly curved sphere.

The specific implementation process is as follows:

the liquid pump 4 on the water outlet pipe 3 pumps the water in the cooling tank 1 into the spray header 10, and the water is sprayed out of the spray header 10 and then falls freely. The suction pump 7 is capable of sucking air from the cooling box 5, which flows from the air inlet 8 to the air suction opening 6, i.e., from below, in a direction opposite to the flow direction of the cooling water, effectively reducing the temperature of the cooling water, and evaporating and sucking a small portion of VOC therein out of the cooling box 5. When falling freely, water contacts with the first sieve plate 11 and the active carbon particles on the first sieve plate, then flows into the second sieve plate 12, and because the first sieve plate 11 is in a bent shape, water flow can be converged at the bottom center of the first sieve plate 11 and then flows downwards, so that the water flow is prevented from entering the one-way air valve 9. When the water in the cooling tank 5 is sufficiently gathered, the activated carbon particles on the second sieve plate 12 are soaked in the water to continuously absorb the VOC. The liquid pump 4 on the inlet pipe 2 then feeds the water into the cooling tank 1 again.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that to those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the present invention.
