Description

Technical Field

[0001] This utility model relates to the technical field of sand aggregate precooling system, specifically a sand equalization device for the upper inlet of a sand cooling box. Background Technology

[0002] A pre-cooling system for sand aggregates refers to cooling sand aggregates directly or indirectly. Direct cooling methods include vacuum and nitrogen cooling, while indirect cooling includes indirect heat transfer cooling using cold air or cold solutions.

[0003] After being screened by a vibrating screen, the sand aggregate falls into a sand cooling box. The screened sand aggregate can be spread relatively evenly in the sand cooling box, but most of the aggregate always accumulates in the center of the sand cooling box. Therefore, how to make the sand aggregate spread evenly in the sand cooling box and how to make the sand aggregate cool evenly are some of the problems that need to be solved in the current application of sand aggregate precooling system. To this end, a sand equalization device is proposed at the upper inlet of the sand cooling box. Utility Model Content

[0004] The purpose of this invention is to provide a sand equalization device for the upper inlet of a sand cooling box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sand equalization device for the upper inlet of a sand cooling box, comprising a sand cooling box inlet, two fixed seats fixedly connected to the top of the sand cooling box inlet, a linear slide fixedly connected to the rear side of each of the two fixed seats, a sliding block slidably connected to the outer side of the linear slide, a common rake rod fixedly connected to the top of the two sliding blocks, and multiple plastic rake teeth fixedly connected at equal intervals to the bottom of the rake rod.

[0006] More preferably, a motor is fixedly connected to the rear side of one of the linear slides on the right side.

[0007] More preferably, the motor is electrically connected to an external control panel via a conductor.

[0008] More preferably, the number of plastic rake teeth is twelve to fifteen.

[0009] More preferably, the structure of the plastic rake teeth is wider at the top and narrower at the bottom.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the sand aggregate falls into the sand cooling box, it forms uneven bulges. When the motor is started, the motor drives two sliding blocks to slide on corresponding linear slides. The sliding blocks drive the rake rod to move, and the rake rod drives multiple plastic rake tooth boxes to move forward. The plastic rake teeth move back and forth to sweep the sand aggregate that exceeds the upper surface of the cooling box into the gaps between the heat exchangers, so as to achieve uniform distribution of the sand aggregate in the sand cooling box. The sand aggregate enters the sand cooling box and is leveled by the sand leveling device. The leveled sand aggregate has a larger contact surface with the heat exchanger in the sand cooling box, avoiding waste of cooling capacity. The leveled sand aggregate has a more uniform heat exchange in the sand cooling box. Attached Figure Description

Two fixed seats 2 are fixedly connected to the top of the sand cooling box inlet 1. Linear slides 3 are fixedly connected to the rear sides of each of the two fixed seats 2. Slide seats 4 are slidably connected to the outer sides of the linear slides 3. A single rake rod 5 is fixedly connected to the top of the two slide seats 4. Multiple plastic rake teeth 6 are fixedly connected at equal intervals to the bottom of the rake rod 5. When sand aggregate falls into the sand cooling box, it forms uneven bulges. A motor 7 is started. The operation of step 7 drives two sliding blocks to slide on the corresponding linear slide 3. The sliding block 4 drives the rake rod 5 to move, and the rake rod 5 drives multiple plastic rake teeth 6 to move forward. The plastic rake teeth 6 move back and forth to sweep the sand aggregate that exceeds the upper surface of the cooling box into the gap between the heat exchangers, so as to achieve uniform distribution of sand aggregate in the sand cooling box. The sand aggregate enters the sand cooling box and is leveled by the sand leveling device. The leveled sand aggregate has a larger contact surface with the heat exchanger in the sand cooling box, avoiding the waste of cold energy.

[0021] In operation, this invention works as follows: When sand aggregate falls into the sand cooling box, it forms uneven bulges. The motor 7 is started, and the motor 7 drives two sliding blocks to slide on corresponding linear slides 3. The sliding blocks 4 drive the rake rod 5 to move, and the rake rod 5 drives multiple plastic rake teeth 6 to move forward.
