Description

Technical Field

[0001] The utility model relates to the technical field of coated sand production, in particular to a coated sand cooling device. Background Art

[0002] Coated sand is a special solid particle, which is composed of a polymer, a filler and an auxiliary agent. Coated sand can be applied to the production of artificial flowers, stationery, handicrafts, food packaging, etc.

[0003] After production and processing, the temperature of the coated sand is relatively high. In order to realize the later packaging of the coated sand, a cooling device is used to dissipate the heat of the coated sand. When the current cooling device dissipates the heat of the coated sand, the coated sand is directly put into the cooling box, and the coated sand is dissipated by the rotation of the stirring blades and the cold air discharged from the cold air pipe. Since the coated sand will agglomerate after heating, and the cooling device directly puts the coated sand into the cooling box without preliminary heat dissipation, the agglomerated coated sand prolongs the later cooling time; and because most of the cold air pipes are installed above the cooling box, and the cold air pipe is easy to cool the surface of the coated sand when blowing air, it is difficult for the coated sand at the bottom to contact the cold air, thus affecting the cooling efficiency of the coated sand. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of slow cooling efficiency of coated sand in the prior art, and to propose a coated sand cooling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A bracket, a heat dissipation cylinder and a guide rod are respectively and fixedly installed on the box body. A guide block is slidably sleeved on the guide rod, and a filter cylinder for filtering the coated sand is integrally connected between the two guide blocks. A rotating shaft two is rotatably installed in the box body, and a connecting block is installed on the rotating shaft two. A mesh plate for stirring the coated sand is arranged on the connecting block. The first support plate and the stirring blades are arranged on the rotating shaft two. A second support plate and a filter screen are respectively and fixedly installed on the rotating shaft two, and a second cold air pipe for cooling the coated sand is arranged on the second support plate.

[0007] Preferably, a water tank and a condenser are respectively arranged on the box body, and a condensate water cavity corresponding to the water tank and the condenser is opened in the box body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Reference Figures 1 - 4 , a coated sand cooling device, including a box body 1, stirring blades 15, and a first support plate 12, and a first cold air pipe for cooling the coated sand is provided on the first support plate 12. Supplementary explanation, the first support plate 12 and the second support plate 13 can store cold air and discharge it into the box body 1;

[0022] A bracket, a heat dissipation cylinder 2, and a guide rod 3 are respectively fixedly installed on the box body 1. A water tank and a condenser are respectively provided on the box body 1, and a condensate water cavity corresponding to the water tank and the condenser is opened in the box body 1. Through the mutual cooperation of the water tank and the condenser, the cold water can always be kept cool during the flow and cool down the box body 1;

[0023] A guide block 4 is slidably sleeved on the guide rod 3, and a filter cylinder 5 for filtering the coated sand is integrally connected between the two guide blocks 4. The guide rod 3 is vertically arranged on both sides of the box body 1, and the filter cylinder 5 is a hollow structure with an open top. The guide rod 3 plays a role in guiding and limiting the guide block 4. By setting the filter cylinder 5 as a hollow structure with an open top, the coated sand can quickly discharge heat energy outside the filter cylinder 5 in the filter cylinder 5;

[0024] A second rotating shaft 8 is rotatably installed in the box body 1, and a connecting block 10 is installed on the second rotating shaft 8. A mesh plate 11 for stirring the coated sand is provided on the connecting block 10. The second rotating shaft 8 drives the connecting block 10 and the mesh plate 11 to rotate in the filter cylinder 5, so that the coated sand can be initially cooled and loosened in the filter cylinder 5, thereby reducing the cooling time of the coated sand;

[0025] A motor 6 is fixedly installed on the bracket, and an output end of the motor 6 is fixedly connected to a first rotating shaft 7 that is in transmission connection with the second rotating shaft 8. The first rotating shaft 7 and the second rotating shaft 8 are both vertically arranged, and a transmission belt 9 is connected between the first rotating shaft 7 and the second rotating shaft 8. The transmission belt 9 is a synchronous belt, and the synchronous belt has the advantages of accurate transmission ratio and no slipping, so that the first rotating shaft 7 and the second rotating shaft 8 can be driven at the same speed;

[0026] The connecting block 10 and the second rotating shaft 8 extend to the upper end position inside the filter cylinder 5. A locking bolt corresponding to the second rotating shaft 8 is threadedly connected to the connecting block 10. When the processing of the coated sand is completed, the locking bolt is removed to disconnect the connection between the connecting block 10 and the second rotating shaft 8, so that the filter cylinder 5 can be detached from the box body 1, and the filter cylinder 5 can be cleaned later after use;

[0027] The first support plate 12 and the stirring blades 15 are arranged on the second rotating shaft 8. A second support plate 13 and a filter screen 14 are respectively fixedly installed on the second rotating shaft 8, and a second cold air pipe for cooling the coated sand is provided on the second support plate 13. The first support plate 12, the stirring blades 15, the filter screen 14, and the second support plate 13 are arranged from top to bottom, and the filter screen 14 is horizontally arranged;

[0028] The driving of the motor 6 causes the first support plate 12 and the second support plate 13 to rotate. The first cold air pipe on the first support plate 12 can dissipate heat from the top position of the coated sand, and the second cold air pipe on the second support plate 13 can dissipate heat from the bottom position of the coated sand. The filter screen 14 can intercept the coated sand so that the coated sand will not block the second cold air pipe. By dissipating heat from the upper surface and the bottom layer of the coated sand, and then through the rotation of the stirring blades 15 for heat dissipation, the heat energy on the coated sand can be quickly discharged, thereby improving the efficiency of heat dissipation for the coated sand;

[0029] It should be noted that the specific model specifications of the water tank, condenser, and motor 6 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated.

[0030] The functional principle of the present utility model can be elaborated through the following operation methods:

[0031] Put the coated sand to be cooled into the filter cylinder 5;

[0032] The output end of the motor 6 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the second rotating shaft 8 to rotate through the transmission belt 9. The second rotating shaft 8 drives the connecting block 10 and the mesh plate 11 to stir and dissipate heat from the coated sand in the filter cylinder 5. Through the open and hollow structure of the filter cylinder 5, the heat energy on the coated sand is initially discharged outside the filter cylinder 5;

[0033] The initially cooled coated sand loosens and falls into the box body 1 through the filter cylinder 5;

[0034] Through the mutual cooperation of the water tank and the condenser, the cold water can reduce the temperature of the box body 1 in the condensate cavity;

[0035] At the same time, the second rotating shaft 8 drives the first support plate 12, the second support plate 13, the filter screen 14, and the stirring blades 15 to rotate;

[0036] When the multiple stirring blades 15 rotate in the box body 1, they can stir the coated sand in the box body 1, so that the heat energy on the coated sand can be discharged through the heat dissipation cylinder 2;

[0037] When the first support plate 12 and the second support plate 13 rotate, they respectively enable the first cold air pipe and the second cold air pipe to cool the coated sand in the box body 1, so that the heat energy on the coated sand can be discharged outside the box body 1;

[0038] When the coated sand is stirred and cooled for a certain period of time, the coated sand is discharged outside the box body 1 through the discharge port.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
