Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of multi-purpose stove smoke exhaust, and in particular relates to a box-type multi-purpose stove smoke collecting hood. Background Art
[0002] The box-type controlled atmosphere multi-purpose furnace is a heat treatment equipment used in the field of materials science. It can perform various heat treatments such as carburizing, nitriding, carbonitriding, quenching, annealing, etc. under a controlled protective atmosphere. A fume hood is also installed above the door of the box-type controlled atmosphere multi-purpose furnace. It is used to collect the fume discharged from the door after the multi-purpose furnace door is opened to prevent the fume from leaking into the processing workshop and polluting the workshop environment.
[0003] However, the smoke hood installed above the furnace door of the multi-purpose furnace has no leakage prevention measures on the hood body and the smoke exhaust volume is fixed. As a result, a large amount of smoke rushes into the bottom of the smoke hood, and the smoke easily leaks and disperses around the smoke hood, resulting in incomplete collection and discharge of the smoke discharged from the furnace door. Utility Model Content
[0004] Based on the problems mentioned in the above background technology, the utility model provides a box-type multi-purpose furnace smoke hood, which is used to solve the problem that a large amount of smoke rushes into the bottom of the smoke hood due to the smoke hood body having no leakage prevention measures and the slow smoke exhaust speed, and the smoke is easy to leak and drift around the smoke hood, resulting in incomplete collection and discharge of smoke discharged from the furnace door.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A box-type multi-purpose furnace smoke collecting hood, comprising:
[0007] A smoke collecting hood, wherein a smoke exhaust structure is arranged on the top of the smoke collecting hood;
[0008] An anti-leakage component, which is arranged on the bottom peripheral side wall of the smoke hood;

[0010] The wind control component is arranged on the back wall of the smoke collecting hood through a socket, and the wind control component supplies air to the anti-leakage component and the blowing component.
[0011] On the basis of the above technical solution, the present invention also makes the following improvements:
[0012] Furthermore, the smoke exhaust structure includes a main smoke exhaust pipe and two auxiliary smoke exhaust pipes. The main smoke exhaust pipe is arranged on the top of the smoke hood, and the two auxiliary smoke exhaust pipes are symmetrically and obliquely arranged on the surrounding sides of the main smoke exhaust pipe. The bottom ends of the two auxiliary smoke exhaust pipes are connected to the inner cavity of the smoke hood; the inner wall of the intersection of the main smoke exhaust pipe and the two auxiliary smoke exhaust pipes shrinks toward the center of the pipe to form a necking mouth.
[0013] Furthermore, the wind control assembly includes a fan arranged on the back wall of the smoke hood through a socket, and the fan is provided with multiple main exhaust ducts, each of the main exhaust ducts is provided with an auxiliary exhaust duct, and the outlet end of each auxiliary exhaust duct passes through the interior of the smoke hood.
[0014] Furthermore, the anti-leakage component includes an air collecting duct, which is arranged on the bottom peripheral side wall of the smoke hood, and is provided with air inlet pipes with the same number as the main exhaust pipes. Each of the air inlet pipes is respectively connected to the corresponding main exhaust pipe, and a plurality of air nozzles are arranged at the bottom of the air collecting duct.
[0015] Furthermore, the blowing assembly includes air distribution pipes, the number of which is the same as the number of auxiliary exhaust pipes, each of which is assembled at the outlet end of the corresponding auxiliary exhaust pipe, and each of which is provided with a plurality of spray holes vertically upward.
[0016] Furthermore, a mounting bracket is provided on the side wall of the smoke collecting hood.
[0017] Beneficial effects of the utility model:
[0018] 1. The smoke exhaust volume can be effectively increased by setting up the main smoke exhaust pipe and two auxiliary smoke exhaust pipes; by setting up a combination of an air control component and a blowing component, after the smoke enters the bottom of the smoke hood, the wind generated by the operation of the air control component is ejected from the nozzles on the blowing component, so that the smoke in the smoke hood can be accelerated to be blown to the main smoke exhaust pipe and the two auxiliary smoke exhaust pipes. At the same time, the inner wall of the intersection of the main smoke exhaust pipe and the two auxiliary smoke exhaust pipes is configured to shrink toward the center of the pipe to form a necking mouth, so that when the smoke passes through the necking mouth, the smoke can increase the flow speed of the smoke to the upper part of the main smoke exhaust pipe, thereby accelerating the exhaust of the smoke inside and below the smoke hood;
[0019] 2. Through the wind control component and the anti-leakage component, the wind generated by the operation of the wind control component is ejected downward from the air outlets on the anti-leakage component, so as to form an enclosed wind curtain under the bottom of the smoke hood to prevent the smoke under the smoke hood from dispersing to the sides of the smoke hood.
