Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a dehydration condenser for producing polyurethane stock solution. Background Art

[0002] The full name of polyurethane is polyurethane, which is a high molecular compound. Polyurethane has two major types: polyester and polyether. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam material, and has smaller compression deformation. It is used as packaging, sound insulation and filtration material.

[0003] The patent with publication number CN214861292U discloses "a dehydration condenser for the production of polyurethane raw liquid", which includes a No. 1 tube and a No. 2 tube. The mounting tube is sleeved on the outer surface of the No. 1 tube, and the No. 1 sleeve plate is connected to the inner surface of the mounting tube by a fixed plate, and a sleeve ring is movably clamped on the surface of the No. 1 sleeve plate, so that the side of the sleeve ring is fixedly connected to the blade, and the blade is blown by the blown-in water vapor to drive the blade to rotate, so that the rotation of the blade drives the cleaning rod to rotate to complete the cleaning of the inner walls of the No. 1 tube and the No. 2 tube, effectively clean the scale and improve the condensation effect. However, the device cleans the dirt after it is generated. According to the above shortcomings, the present application installs a filter before the device is used. The filter can prevent the dirt in the water vapor from entering, and can effectively prevent the dirt from appearing on the inner wall of the condenser tube. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a dehydration condenser for producing polyurethane stock solution.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dehydration condenser for the production of polyurethane raw liquid, comprising: a connecting sleeve, a first filter screen for filtering dirt in water vapor, characterized in that: a support block is arranged inside the connecting sleeve, the support block is provided with a first groove and a second groove, an inclined block is fixed between the first groove and the second groove, a pressure plate is slidably connected to the inner wall of the second groove in the vertical direction, a round rod is fixed on the top of the pressure plate, and a return spring is arranged outside the round rod.

[0006] The utility model can be further configured as follows: the first filter screen is provided with a transverse groove and a circular groove, the interior of the transverse groove is slidably connected with an L rod, and the interior of the L rod is provided with a ladder block via a telescopic spring.

[0007] The utility model can be further configured such that the number of the support blocks is two, and the two support blocks are symmetrically arranged up and down.

[0008] The utility model can be further configured such that the first filter is a HEPA filter.

[0009] The utility model can be further configured such that one end of the round rod extends to the outside of the supporting block.

[0010] The utility model can be further configured such that the bottom of the return spring contacts the top of the pressure plate, and the top of the return spring is fixedly connected to the top of the second groove.

[0011] The utility model can be further configured such that a pressing area is provided at the top end of the round rod.

[0012] The utility model can be further configured such that the pressing area is made of a soft silicone material, thereby preventing finger injuries during pressing.

[0013] The utility model provides the following beneficial effects:

[0014] 1. When the L rod extends into the first groove, manually move the L rod inside the horizontal groove. During the movement, the ladder block retracts into the inside of the L rod under the pressure of the inclined block. Then, when the L rod moves into the second groove, the pressure of the inclined block on the ladder block disappears. Then, under the action of the telescopic spring, the ladder block extends out. At this time, the ladder block will be fixed in the second groove and cannot move. This is conducive to connecting the first filter screen and the support block. Then, the first filter screen filters the dirt in the steam, which can effectively prevent dirt from appearing on the inner wall of the condenser tube, and there is no need to clean the inner wall of the condenser tube.

[0015] 2. Push the second filter into the interior of the connecting sleeve. At this time, the pressing block moves to the interior of the hollow chamber. When the pressing block moves in the hollow chamber, it will press the gas inside the hollow chamber. Then the gas inside the hollow chamber will enter the interior of the airbag along the trachea to expand the airbag. The expanded airbag can fill the gap between the second filter and the connecting sleeve, which is helpful to prevent dust from entering through the gap. At the same time, the expanded airbag can hold the second filter. BRIEF DESCRIPTION OF THE DRAWINGS
